+{I'd like to start with an old game by one of the deepest positional players ever, Rubinstein. This game is not exactly unknown, but I will propose a new perspective on this game that seems helpful.  It seems to me that the key to understanding what is going on in this game is to think about black as playing noncommittal, solid moves, and most importantly REACTING to mistakes by white.  This game emphasizes the negative side of pawn moves and in many cases Rubinstein's key moves come AFTER pawn moves by white have weakened his position in some way.  And before we get into the game I would also tentatively suggest that it makes a good "solitaire chess" exercise if you're up for it.  I haven't awarded points for each move or anything like that, but if you configure your program so you can't see the moves and make a quick run through with the arrow keys, comparing your guesses to Rubinstein before you look at my notes, I think it would make the game and notes that much more valuable.} 
+1. e4 e5 2. f4 Bc5 3. Nf3 d6 4. Nc3 Nc6 5. Bb5 $5 
+{The first four moves might be out of fashion, but this move is the first to seem slightly odd.  Clearly the bishop is best on c4; because white can, and eventually will probably exchange on e5, the bishop will support the rook on the open f-file bearing down on f7 (although it is a complication that white cannot castle to do this), and the bishop cannot be challenged by ...d5.  Instead of playing the most natural move, Alapin pursues a more concrete, but one-dimensional idea.} 
+5... Bg4 6. d3 Nge7 $1 
+{There are many ways to look at this move, which seems to be clearly best if less obvious than 6...Nf6.  I would like to see it as black's first "reaction" move, against the slightly odd 5.Bb5.  After black castles and eradicates the pin, this bishop essentially stops contributing to the fight for the center, since Bxc6 can be met with a recapture by the knight.} 
+7. h3 Bxf3 8. Qxf3 O-O 9. f5 $6 
+{In this game, it seems that every time white moves a pawn, it causes him trouble.  Here he returns the bishop pair (although it wasn't easy to see what to do with it) and takes the pressure off of the center, making it easier for black to play ...d5.}

+14... c6 $1 15. Na3 
+{This is a very ugly knight.  Besides that, the crux of black's advantage is that he has the lever to open the d-file WHEN HE IS READY TO DO SO, by way of which he takes over the game.} 
+15... Qb6 $5 16. Qxb6 axb6 17. c3 
+{This creates a serious weakness on d3.  One implication is that now exd5, trying to liquidate into a slightly worse position, becomes impossible as black recaptures with a rook and puts too much pressure on the weak pawn.  Less obvious is that after black exchanges d-pawns, the square remains weak, and in fact white's entire queenside, especially the a4 and c4 squares.  This is because, with c2-c3 already played, b2-b3 creates further weaknesses.  Nonetheless, it was already difficult for white, and the idea to get his knight into play seemed reasonable.}

+17... Rfd8 $1 
+{Of course the a8-rook, since it is doing something where it is, should be the last to move.} 
+18. Rf2 Rd7 $1
+{And this is the key; black is able to take over the d-file because of his pawn lever.} 
+19. Nc2 Rad8 20. Re1 dxe4 21. dxe4 Nc8 $1 
+{And this can be seen as the second "reaction move".  Because 17.c3 created weaknesses on a4 and c4, black prepares to bring his knight within reach of those squares.} 
+22. Rfe2 b5 23. Na1 Nb6 24. Nb3 Na4 $1 25. Kf2 c5 26. Rc2 g6 $3 
+{Everything was going nicely on the queenside; black has a grip on the d-file and a very bothersome knight while white's pieces just look jumbled up, and suddenly Rubinstein makes a move on the side of the board we had forgotten all about.  It seemed he wasn't interested in playing out ...c4 Nc1 on the board yet since it gives white information before black is ready to strike.  Instead, it's time to calmly improve matters some more, waiting for white to make more concessions before black REACTS.  And ...g6 fxg6 does improve matters because now black can create a passer at any moment with ...f5.}

+{The following recent game by Nisipeanu, who made an amazing run in the World Championship in Vegas a couple of years ago, shows, at the same time, some good solid chess, and the ability to break out of normal patterns when it is advantageous to.}

+{I have to admit that I'm not well-versed in the theory of this variation with 9.Nd5 instead of 9.Bxf6, but I know enough that this move causes me to sit up and pay attention. The idea of the 9.Nd5 line, as I understand it, is that black cannot get away with challenging the knight this easily. Presumably the kingside weaknesses are too much if black is also without his dark-squared bishop. But black says: "show me".} 
+12. Nxf6+ gxf6 13. Bd3 
+{The bishop often stays put for a long time in these lines, so this isn't an obvious case of "finish development, get castled",... especially if you see how white continues! Regarding development of the bishop to d3 in general - it is meant to be prophylactic, I think, against ...d5 and ...f5, but white has to show some care in that the bishop can find itself misplaced if black gets an opportunity to play ...f5 as a sac and then start rolling the center.} 
+(13. Nc2 {seemed more flexible, but white will still have to decide what to do at some point.})
+13... Bb7 14. Qe2 
+{Keeping his castling options open, but soon he will have to choose and he will certainly go kingside...} 
+14... d5 15. O-O-O $5
+{Well I'll be damned! Actually, looking over this game a second time around, this seems very logical. If you read my notes to last week's game, you might even agree that this is a "reaction" move agaist 14...d5, the possibility of which white has cleverly kept open, but, but... the Na3 is supposed to go to the center, white is supposed to play a4 to activate the a1-rook, etc. Patterns can be useful, but they can be limiting as well. Apparently Nisipeanu is less susceptible to being limited by patterns than I am.} 
+15... Qc7 16. Nc2 O-O-O 17. exd5 
+{Opening the center and preparing some exchanges. In general, white's advantage can be expected to grow as more pieces are exchanged, because his pawn structure is better. One possible modification to note, however, is that if white keeps the knights on the board, this may prove useful to tickle the weak a6 and c6 squares around black's king.} 
+17... Kb8 18. Be4 f5 19. d6 Rxd6 20. Bxb7 Kxb7 21. Rxd6 Qxd6 22. Rd1 Qe6 23. Nb4 Rc8 
+(23... Nc6 $5 24. Nxc6 Kxc6 {might come into consideration, reasoning along the same lines as we did above, that keeping knights on the board is in white's favor. White is clearly somewhat better here too, but it looks to me that his advantage can be kept within bounds. One complication is that most pure pawn endings are probably winning for white, but I don't see how white can force this.}) 
+24. Qd3 e4 
+{I don't like this move. Black almost forces white to penetrate into the position, which he was probably intending anyway. In black's defense, it takes some calculation to see how bad this actually is.} 
+(24... Nc6 {would be my choice again, but it isn't a panacea.} 25. Qd7+ Rc7 26. Qxe6 (26. Qd5 $1 {is the machine's (Hiarcs) suggestion, and looks very hard to meet, for example:} 26... Qxd5 27. Nxd5 Rd7 28. Nf6 Rxd1+ 29. Kxd1 h6 30. Ng8 h5 31. Nh6) 26... fxe6 27. Nxc6 Kxc6 {and black is OK in this line.}) 
+25. Qd7+ Rc7 26. Qxe6 fxe6 27. Rd6 a5 28. Na6 $1 
+{The second move from white in this game to take me completely by surprise. The a6-square seems remote and unlikely, not least because the knight is nearly trapped there. For these reasons I would be tempted not to look at it at all. But after you see it, it becomes clear that 28. Na6 is the winning move, since in this case white's rook penetrates and becomes unanswerable after the slightly tricky knight exchange.} 
+(28. Nc2 {also looks pretty good, however, due to the following line:} 28... Rc6 29. Rd7+ Rc7 30. Rxc7+ Kxc7 31. Nd4 {and white wins a pawn.})

+{The following game is hard-fought, and, please bear in mind that I will get a lot of things wrong in a hard-fought game between GMs, especially since I haven't used anyone else's notes as a benchmark. Nonetheless, hopefully my impressions are interesting, if only for their mistakes... Regarding the game (from now on the caveat "as I see it" is implicit), the opening features an original rook maneuvre which leads to crushing pressure on the queenside. His opponent puts every obstacle in the way, offering a pawn to organize his pieces. White declines the pawn on the first pass and black gets a barely playable game, but after black misses his chance to break out, white goes into "technical mode" and achieves a pleasant win.} 
+1. d4 Nf6 2. Nf3 $5 
+{This could be just a move-order trick, or a signal that white is going to play one of the systems without c2-c4, for example the Torre (3.Bg5) or the Zukertort (3.e3, 4. Bd3, 5. b3,...). As a generality, if white is just going to play c4 later, I think this move loses more flexibility than it gains.  However, once you know your own and your opponent's repertoire this may not be the case. For example black cannot get a Benko proper now if white doesn't want to co-operate. This may have been what black had in mind, because he isn't happy to let white transpose to one of various standard openings, so the game goes down a relatively original path.} 
+2... c5 
+(2... d5 $5 3. c4 e6 {This is an important nuance to be aware of. By going into the QGD after white has played Nf3, black more or less avoids the Exchange variation, for example:} 4. cxd5 exd5 5. Nc3 c6 6. Bg5 Be7 7. e3 Bf5 $1 {and black has equalized.  Black is never able to get in ...Bf5 so painlessly in the QGD Exchange proper.})

+{Bravo! This is the "I'm not going to let you get back into a normal opening" move.} 
+(3... d6 4. c4 e6 5. Nc3 exd5 6. cxd5 g6 {was also possible, and would be another of the lines that aims to "punish" white for an early Nf3. At the moment, the most dangerous line against the Benoni involves an early f2-f4.}) 
+4. Bg5 Ne4 5. Bf4 Bb7 6. a4 Qa5+ $2 
+{A thematic looking idea which doesn't work, but Hebden's continuation was not so easy to foresee. It takes a lot of courage to explore these variations that are off the beaten track, and for that Degraeve gets my respect. I remember annotating some of my own games a couple years ago that reached distinctly messy positions, and it was incredible to me how many mistakes and outright blunders were made in such games. Even 450 points up the rating ladder, I suspect that it isn't easy.}

+7. Nbd2 Bxd5 8. axb5 Qd8 9. Ra4 $1 
+{This is the sting. Without this move, black is behind in development, but had good prospects with a grip on the center, and a better pawn structure. Now he is losing the fight in the center, coming under pressure on the queenside, falls further begind in development (e4 hitting the bishop), and is fighting to stay alive.}

Instead of taking the pawn, white prefers to triple pieces on the a-file and simply maintain the pressure.

+{I decided not to show any of my other games from the World Open because frankly, on closer inspection, they weren't as interesting as I had originally thought. Instead, I want to look at a very complicated win by John Nunn. The hardest part of annotating this game is to avoid just copying the excellent analysis that has already been written by Nunn himself, which I have access to in _Understanding Chess Move by Move_. Fortunately I saved some independent analysis done with Fritz after I had first seen the game and before I saw any notes, which contained several ideas that didn't exactly follow Nunn. It is doubtful I could have been as open-minded if I had seen his analysis first. In terms of possibly significant differences between the two analyses, I can point out 17...Bxf5 followed by 19...Qb4, where I went into greater detail but ultimately agreed with Nunn, and 22...Ne8, which I think is a possible improvement. By the way, my intention in presenting this game is not to topple Nunn's analysis, which I think would be quite hard. Instead it is an attempt to expand his work that considers some lines he might have just been strong enough to dismiss offhand, and most importantly it is just an excuse to introduce an awesome game to anyone who hasn't seen it already.}

+{The following game can best be described as "mind-blowing", and it has been among my favorites for a long time. Therefore, one of the first games I intended to present as a "Game of the Week" was this one. The only thing that has held me back is that it proved incredibly hard to produce competent annotations. One of the problems is the same one I mentioned last week; that I can't just reproduce Shirov's notes from _Fire on Board_ so I have to diverge or improve on them. Of course diverging is easier! In most cases, my independent silicon-assisted notes (written as a first draft) emphasized slightly different points, and yet were accurate enough to keep, at least as a framework. However, at some critical moments only Shirov's notes approached what was really going on in the position. You will see how I dealt with the dilemma on black's twentieth move; hope you find it to be a reasonable solution.  Anyway, enjoy the game.}

If you check your d   atabase, you will reach the conclusion that I played twenty moves of theory, and then my first independent move was a timid mistake that lost. However, "cross my heart and hope to die", I was playing on my own after move seven! When my opponent informed me after the game that it was all theory, I was shocked and somewhat annoyed, but, I won't lie to you, my overwhelming feeling was excitement. Wow, I had created all of these moves at the board! And this is why the game is a breakthrough, because now I know that, at least when all of the conditions are right, I can play chess at a high level. I think this confidence had something to do with my strong finish in the tournament.}

+{This game fascinated me for two reasons.  For one thing, because black appears to proceed so smoothly towards a completely dominating position around move 30.  Usually this indicates a big understanding difference between the opponents, but Beliavsky is a strong GM. What happened?... and this brings us to the second reason.  There is one move by black in this game that does not quite fit the "smooth" mold; it is absolutely dynamite.  If you are using Chessbase Reader to look at this game or something similar, put it into training mode.  I will warn you before the move you should try to guess.}

+10. Nd2
+{Also a weird-looking move but you won't even glance twice if you've played through a lot of Benoni games. Playing the knight to c4 puts pressure on d6 and frees the path for the f-pawn.}

I am not a strong enough player to guaranantee to you the move's objective value, but I can tell you this.  Creativity, and keeping your opponent off balance, wins games.  Outplaying a strong opponent like Beliavsky as completely as we shall see later is not possible if he can predict all of your moves.  So, from a pragmatic point of view, completely sound or not, look for something like this in all of your games, as it can be absolutely devastating.}

After I had completed my notes, I got a copy of Ftacnik's notes for the Informator.  He basically had two interesting things to say.  One was regarding the move 21.Kh1, which he thinks is a mistake.  I have to admit that I don't really understand his analysis, as he seems to be assuming that in any case white must play Ba4xb5, which I didn't agree with.  The second thing that was really interesting was the suggestion of 19.Be2... What do you think is the idea of that move?  That's right, to prevent 19...bxa4!  After the brilliant 19...bxa4 has been discovered, somebody finds 19.Be2, invents a logical explanation which is condensed to one sentence (if you're lucky) in the opening monographs to save space, and theory moves on.  No wonder it is so hard to understand!  The lesson is to look for the games behind the moves, and be reluctant to just accept that one-sentence explanation and be denied the pleasure of discovering what is really, actually going on with 19.Bc2.}

Well, white has played all of the right moves and, further, black has two pieces marooned on the queenside while his king is exposed.  Therefore, at first I naturally assumed that white had something.  But I can't find it!  The computers are very powerful advocates for concrete variations over generalities, and they tenaciously find resources for the material grabber.  Chess thought is already being re-evaluated in many variations (like the Poisoned Pawn, where white can no longer just "say" he has compensation), and this may be one more example.}

+1. d4
+{This game was played in the recent UMBC Open tournament.  UMBC players tend to despise this event because of the high entry fee and the fact that it is required to be considered for team selection.  Nonetheless, there is also a positive aspect to playing basically "at home", and I did well this year.  My fourth round game was probably the best.}
+1... Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5 5. Nge2
+{A perfectly well-known system, of course.  However, one of my weak points is that I have never really settled on a single main defense against 1.d4, and therefore I was already on somewhat unfamiliar ground.  The last time I had faced this move was almost a year ago against Ilye Figler, when I got crushed.  However, even after that game I had not prepared fully.}
+5... cxd4 6. exd4 d5
+{Bengston mentioned after the game that this line is out of fashion, but it was the only one I (sort of) knew.}
+7. c5
+{An ambitious move - also, not to be misleading, the normal move in this position.  Anyway the idea is that if black wants to keep the bishop then white will gain valuable tempi for queenside expansion.  In the game against Figler I had basically ignored white's idea with 7...O-O; this time I knew basically one more move... by the way, this is not the recommended way to learn theory, one move at a time!}
+7... Ne4 8. Bd2 Bxc3
+({It turns out that} 8... Nxd2 {is more highly recommended.  The following is a sample line:} 9. Qxd2 a5 $1 {An important strategic idea that never crossed my mind at the time.} 10. a3 Bxc3 11. Nxc3 a4 12. Bd3 b6 {and black appears to be making a fair fight of it on the queenside.})
+9. Nxc3 Nxd2 $6
+{This basically just hands white a pleasant position.  After I became disillusioned with 9...Nxc3 I didn't see anything else, but the situation actually should not be considered so desperate.}
+(9... Nxc3 10. Bxc3 $1 {Leads to an interesting position.  My impression during the game was that white is just better here, not so much directly due to the bishop pair as due to his queenside wedge.  The c3-bishop looms large, however, if black tries to chip away the wedge by ...b6, or pulverize it by ...e5.  After the game UMBC's chess coach, Igor Epshtein disagreed, opining that ...e5 is not crucial and black can play around the wedge, and since the bishop is not doing that much then black is happy enough to have a knight... okay, verdict?  I dunno.} (10. bxc3 b6 $5 {This is what I was originally thinking about when I played 8...Bxc3, although it is also possible to play 10...O-O first.}))
+(9... O-O {Is another approach, which seems to have theory's stamp of approval.  Black says he likes the e4-knight and doesn't want to exhange it for nothing.  Since 10.Bd3 could be met simply by 10...f5, the critical question is who benefits from changing the pawn structure.} 10. Nxe4 dxe4 11. Bf4 (11. Bc3 Qg5 {is interesting.}) 11... Nc6 12. Bd6 Re8 13. Qd2 e5 14. dxe5 Nxe5 {and black appears to be fine.})
+10. Qxd2 O-O 11. Be2 b6
+{This appears to be almost the only way for black to play.  The idea is to play 12...bc and to gain the c6-square if white re-captures with the b-pawn.  If white takes with the d-pawn, as in the game, then black gets a central majority.}
+12. b4 bxc5
+(12... a5 13. b5 {is terrible.})
+13. dxc5
+{The ambitious decision, which was easy to predict.  My opponent outrated me by about 200 points and so far he has every indication that things will go his way.  After all, I have taken a long time to play moves which are inferior to established theory.  Nonetheless 13.bc was worth a thought.} (13. bxc5 Bd7 {This was my intention during the game.  The following line is not forced, but it proves that white's idea has teeth.} 14. O-O Bc6 15. Rab1 Nd7 16. Rb3 Qc7 {Otherwise 17.Bb5 will be awkward.} 17. Nb5 $1 Bxb5 18. Bxb5 {And white is clearly better.})
+13... Nc6 $1
+{This was the crux of my idea, and it seems to be the best try.  The knight goes to e7 so it can support the center.}
+14. b5
+{Of course nothing could be more natural, and I was counting on this.  Nonetheless, 14.Rb1 should be considered for reasons that I will explain in a moment.}
+14... Ne7
+{The obvious idea is ...e5, but there is another threat that white has so generously helped me to create with his last move...}
+15. O-O
+(15. Bf3 a6 $1 {This is the point.  White's pawns are suddenly crippled in this line.  Therefore he is not able to stop ...e5.})
+15... e5 16. f4
+{After the game white explained that he had been relying on this move, which attempts to break apart my center.  Now enormous complications erupt.}
+16... Qc7 $1 17. c6 d4 $1 18. Ne4 Qb6 $1
+{I apologize for giving myself three exclams in a row... the idea isn't quite that brilliant, and I am not even certain if it is sound.  However, each move is an integral part of black's plan.  If I didn't have 18...Qb6 I wouldn't be able to gain the necessary tempo to protect d4 so I can push in the center, and the center would collapse.}
+19. Kh1
+(19. Nf2 e4 $1 {is a pretty side variation.})
+(19. Bd3 $1 {is more critical:} 19... f5 $5 20. fxe5 fxe4 21. Bc4+ Be6 22. Bxe6+ Kh8 {and the central pawns look very imposing, but a pawn is a pawn and white's position is very active.  I suspect that if you analysed deeply enough it might transpire that white is just winning here.})
+19... Bf5 20. Nd6
+(20. Ng3 {is more stable but probably better for black after 20...e4.  White has a more challenging idea.})
+20... e4 21. g4 $1
+{This move definitely keeps the position from growing stale!  Seriously, the next few moves are highly critical - will black's center collapse or will he be able to make something of it?}
+21... e3
+{Apparently forced.}
+22. Qb4 $6
+{This is the most active square for the queen.  It is true that it allows 22...Nxc6, but then the queen can retreat and everything hangs.  It appears that ultimately this doesn't work, but I admit that I have not had time to analyse this position completely, as it is clearly rich with possibilities.}
+(22. Qc1 Be6 {is very hard to assess, but probably gets preference since the game should be good for black.})
+22... Nxc6 $1
+({The calm treatment with} 22... Be6 23. Nc4 Qc7 {is also possible, and it is also hard to evaluate.  After my choice in the game the position becomes incredibly sharp but then reaches a fast resolution, which was easier on my nerves.  So after a quick check that I hadn't missed anything obvious, I crossed my fingers and played it.  It turns out that it is also best!})
+23. Qa3 d3
+{Forced.}
+24. Bf3 Nd4 $6
+{There are three main ideas behind my sack.  First, the pawns are going to try to net at least a rook.  Second, ...Nc2xa1 can pick up a stray exchange with tempo.  Finally, as Tal said once, white can only take one piece at a time.  However, these reasons are just some attempt to make conceptual sense of a random looking position.  If you really want to know what's going on, then the variations must speak for themselves, and it turns out that there was a better move.}
+(24... Bxg4 $1 {is even stronger.  Black simply gives up a single piece, and leaves white to deal with the multiple threats including ...Nc2, a loose knight, and of course the passers.} 25. Bxg4 Nd4 26. Qxd3 {There is nothing better.} (26. Nc4 Qb7+ 27. Kg1 Qe4 $1 {and black has too many threats.}) 26... Qxd6 {With advantage to black.})

+30. Qe2 h6
+{An important move in any case, so this seems a good moment to get it in.}
+31. a4
+{Possibly the next two moves are too time-consuming... in any case white soon gets into trouble.  31.Rg1 might be better although, frankly, I prefer black here.}

+35. f6 Qxg2+ $6
+{After 35...g6 I probably could have won the endgame.}

Rxa7 Rxf4 {It isn't immediately clear that this position is a win, but analysis with Epshtein revealed that white is hard pressed to meet black's simple, methodical advance.} 41. Kg2 Kg7 42. Ra8 Ra4 43. Ra7 g5 44. Ra6 f6 {etc.})
+36. Kxg2 gxf6 $2
+{Again 36... g6 was correct.  This move is somewhat inexplicable in that now 36... g6 seems more or less obvious to me.  However, during the game I became distracted analysing what happens after 36... g6 if I go for the a-pawn instead of the f-pawn, when things are less clear.  I guess I didn't appreciate the full range of possibilities.  Now the position can even become dangerous to black because white's king is more active.  The finish is played at a low level and it's a shame for such a full-blooded middle game to end as this does.}
+37. Kf3 Kf8 38. Ke4 Ke7 $2
+(38... Rd2 {was much simpler.})
+39. Rb1 f5+ $2
+{This line is at best barely drawing.  My only excuse is that I couldn't belive I was in any trouble after the nice play earlier, i.e., I thought I should be fine through inertia.}
+40. Ke5 f6+ 41. Kxf5 Rd5+ 42. Kg6 Rxa5 43. Re1 Kf8 44. Kxf6 $2
+{I was just starting to appreciate how precarious my position was when this move appeared on the board.  Instead, after 44. f5 white could have made me sweat.  Although I don't see a win, neither do I see a clear way for black to a draw.}
+(44. f5 Ra2 45. h4 Rg2+ 46. Kxf6 Rg4 47. Rb1 {is a starting point for analysis.  Again I have to admit that I'm not ready to give an opinion.  Hopefully you can forgive me and the game provides enough food for thought as it is.})
+44... Ra6+
+{And white accepted the draw.  All in all, neither of us probably deserved less... or more.}

+{He mentions at this point that the French is the refutation to 1.e4,... and you might be wondering where the hell that statement could be coming from.  Well I would just like to point out that, in serious tournament games, he has played 1.e3 e5 2.d3 d5 3.d4 many times.}

Nf6 5. exd5 Qxd5 {is the simplest way to equalize in my opinion.}) 5. Nb3 Bb6 6. exd5 exd5 {And here I think black is more or less happy anyway.  True, white has forced the IQP (which wouldn't have been possible after 4.ed5 Qd5!?), but this is a good version compared to the lines where black has to play ...Be7xc5 as two moves.})
+4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 7. Ne2 cxd4 8. cxd4 Nb6 $5
+{8...f6 is the normal main line and is in my opinion better because it challenges the center.  However, black's idea in the game should not be completely underestimated.  When one side has lots of space to maneuver it is typically thought that he has an "easier position to play" which is not true.  What is true is that he has an objective advantage because he can decide when to strike.  However, he has to make the decision over the board and this can be a very hard call to make.  If he strikes at the wrong moment he will free his opponent's pieces and hand over the advantage along with a complete psychological reversal.}
+9. O-O Be7 10. f4 g6 11. a3
+{11.Nf3 looks better as it isn't clear yet that ...Nb4 will be a problem.}
+11... a5 12. b3 $1

+12... Bd7 13. g4 $5
+{This looks OK to me.  True, white will have to be patient before a direct assault with f4-f5 is going to work.  However, this stakes out some space and prevents ...h5, so I don't see a problem.}
+13... Qc7 14. Bb2 f5 $1
+{Black finds a strong defensive resource. This immediately neutralizes whites kingside play. This is what puts question to whites early g4.}

+16. Nf3 a4 17. b4 O-O 18. Rc1 Qd8 19. Bc3 $2
+{A natural move but the wrong one.  This is actually an extremely interesting position that Dave and I analysed at some length.  I think the correct plan is Kf2!! (which he mentions), followed by Ke3, h4-h5 etc.  The move he played in the game is completely natural but it simply doesn't work.  This was hard enough to see in hindsight, and I envy the player that could see it at the board!}

+26... Rc6 27. Ne3 Rfc8 28. Nc3

+{I'm not so enthusiastic about this move.  In my opinion the position is roughly even now (the last great chance for white was 19.Kf2), and this is asking for trouble.  Of course such a move may be justified, for instance in time trouble when you need to produce a decisive result.  Even if it doesn't work and you become slightly worse, it may actually improve your winning chances by giving your opponent an obligation to avoid the draw!

After 13...Bh6 14.Ng5 Ngxe5 besides the fact that black is up a pawn, the pin is extremely annoying.  If white breaks it with 15.Be3 he also takes the pressure off of black's center and he is more or less just a pawn down for nothing after 15...O-O.  If white plays 15.Kb1 f6 16. Ne6 Bxd2 etc. forces an effective queen exchange.  However we shouldn't be too smug about the fact that white made the wrong move here.  One of the hardest things is when you have the advantage, to choose between several attractive lines and find the one which doesn't allow any counterplay, because first of all you have to see why the other moves do allow counterplay!_}

I would suggest that this is the type of game a player should work on if they are going to improve, because it will tend to bring a lot of the player's weaknesses to the fore: boredom, impatience, lack of consistency, etc.  White did good work annotating this game and if you don't see where I'm coming from it might help to go through the game a second time and try to take away a certain self-critical method that could be applied to your own games._} 1/2-1/2

+{In April, mainly out of boredom playing the same opponents over and over in regular chess, sometimes losing to them, I decided to try "internet correspondence" on itsyourturn.com. At the beginning I had to spend about a month beating some players who probably played about 1200 OTB level, but in the second round things are already getting more interesting, as in the following game.}
+1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5 Be6 9. Nbd2 Nc5 10. c3 d4 11. Ng5 Bd5 12. Nxf7
+{It was only here that I looked up the theory and learned that 12.Nxf7 was a move... it seemed more interesting than any of the alternatives so I just played it. I figured that since Svidler had played it once against Anand it couldn't be too bad, so I would just go where the currents took me and figure things out as I went. It turned out that this led to a very interesting struggle.}
+12... Kxf7 13. Qf3+ Ke6 14. Ne4
+{Before I played this I had got around to studying the position myself and I decided I liked this move better than Svidler's approach. 14.Ne4 is natural; it clears the way for the c1-bishop, the f-pawn, and it has some less obvious points as well.}
+(14. Qg4+ Ke7 15. e6 $5 {was the continuation in the extremely interesting game Svidler-Anand, Dos Hermanos, 1999. White intends to keep open the e-file and attack at any cost.} 15... Bxe6 16. Re1)
+14... Nxe4 $1 15. Qxe4
+{Since the c1-bishop is unleashed black cannot meet 16. Qg4+ anymore with 16...Ke7. Therefore, the main threat is Qg4+, Qf5+, and e5-e6, when there is a mate threat to f7 and the bishop on d5 suddenly hangs. Black's move 15...Ne7 seems like the only way to meet this threat tactically, but since it involves backing up, burying the f8-bishop and leaving the king in the center, I ought to have good compensation for the piece.}
+15... Ne7 $1
+(15... Be7 16. Qg4+ Kf7 17. Qf5+ Kg8 18. e6)
+(15... dxc3 16. Qg4+ Kf7 17. Qf5+ Kg8 (17... Ke8 18. e6 Ne5 19. Qh5+ $1 g6 20. Qxe5 {is also good for white although of course a bit more resiliant than 17...Kg8.}) 18. Qe6+ $3)
+16. Bg5 Bxb3 17. Qg4+ $1
+{This is an important intermezzo that might not be so easy to spot over the board. I didn't see what would happen but I saw that I had to play it or else I would lose my compensation for the piece, so I was still flowing with the current...}
+(17. axb3 Qd5 18. Qg4+ Nf5 $1 {is an important option that black does not have in the game. This is why I played the queen check first.}) 17... Kf7 18. axb3 Qd5 19. c4 {19.f4 immediately might be possible, but it seemed obvious to play this first. The tactical idea is just that if black leaves the diagonal then Qf3+ picks up a rook. c6 is apparently a worse square for the queen because she is actually well-placed in a centralised position; for example f4-f5 is met by just ...Qxe5. However in the game there is another important consideration that comes out; from c6 the queen makes a defense possible with ...Ng6, so 19.c4 may have actually helped black.}
+(19. f4 {deserves analysis})
+19... bxc4 $1
+{Playing this before ...Qc6 avoids cxb5.}
+(19... Qc6 20. cxb5 axb5 21. e6+ Ke8 22. Rxa8+ Qxa8 23. Bxe7 (23. Qxd4 Qd5 24. Qa7 Qxe6 25. Qxc7 {is also tempting since black's pieces look idiotic, but I don't see a clear way to win some material back or force mate.}) 23... Bxe7 24. Qxd4 Qc6 25. Qxg7 Rf8 26. Qxh7 Qxe6 27. Qh5+ Kd8 28. Qxb5 {and white is probably a lot better, since a queen trade is no longer an escape for black with three menacing passers.})
+20. bxc4 Qc6 21. f4
+{Frankly this was the only move I considered since it seemed positionally sound to push the passers ahead. Black has some serious problems to unravel before I play f5-f6 or else he will be losing ... frankly I didn't see how he could do it. If I had appreciated the strength of ...Ng6 then I might have considered grabbing another pawn here with 21.Qxd4.}
+21... h6 $1
+{Black has a well thought out defense. This move gains a tempo because of my 24th move.}
+22. Bh4 h5 23. Qh3 Ng6 $1
+{Nice, intending to meet f4-f5 with ...Nxe5. Qf5+ seems like it ought to be disruptive but it doesn't do anything and gets in the way of my pawns.}
+24. Bg5 Bc5 $2
+{During the game I was more worried about how to get compensation after 24...Be7, and probably justifiably. Although 24...Bc5 seems logical, it is probably a mistake if black cannot find any improvements on the game and 38.Rf5 is as strong as it appears.}

If I can get back material, and retain my attack?! 30.Qd3 is not the most obviously agressive move but it threatens f5-f6 and Qg6, and stops defenses based on d4-d3+.}
