Sunday, Game #1:
6W. Fisher's preferred move against the Najdorf. I had mostly played for years Bg5 here, but had little success with it OTB. I've been doing much better with this line.
7W. Bb3 is the standard line, but in Palliser's book on the Najdorf he gives the line starting with 7 O-O where if Black plays 7 ...... Ndb7? White follows with 8 Bxe6 fxe6 9 Nxe6 Q moves 10 Nd5 Nxd5 11 exd5 with the Knight anchored on e6. I got to play this against a pretty good player in the NYS Open in 2009 and scored a quick smash. This game was very much in my mind, perhaps too much as it turned out.
7B. An aggressive response by Black.
8B. A risky move by Black where 9 Re1 by White scores very well. But:
9W. If Black blocks the defense of the e6 pawn by the Bishop, the sac is a standard one in this line. Glen didn't think it was sound in the post-mortem, but it's been played 7 times in Chessbase's database with a 57% score. I think it's perfectly playable and suits my aggressive temperament.
10B. This takes the game out of book and is an error in my IMO. Black has played Qb6 in all 7 games in the database and that seems clearly superior. In virtually every line we reviewed afterwards, the Queen returns to Qb6 anyway, so Black is simply wasting a tempo.
11W. I had the prior game in mind here but:
12W. I should listen to greenpawn more ("look at checks first"😉; the intermezzo check 13 Qh5+ is much stronger. White's attack looks very strong after either Ke7 or g6 particularly the latter. Simply taking with the pawn allows Black's next an excellent defensive move.
12B. The attack is faltering now; the Knight on e6 must either be retreated (a major concession) or allowed to be exchanged.
13W. A foolish move. Sure, if Black blunders and takes the pawn, Nc7+ wins but the chances of my opponent doing that were remote. I managed to hand him back the tempo, pin the f-pawn so it can't chase the Knight out of e5 and leave a long term weakness on c4.
14W. Another poor choice. 14 Be3 or Bb2 was the only way to keep some sort of attack going. I was counting on 14 ....... Rxf8 15 Qh5+ g6 or K moves 16 Qxh7 where I have 3 pawns for the piece, but even that line leaves Black with better development, attacking chances down the f-file and a nice centralized Knight. As it is, Black has an even stronger response.
14B. White is strategically lost after this, far behind in development, on the defensive, down in material and with a weak Queenside.
The rest isn't worth much discussion; I could have legitimately resigned after the forced exchange of Queens. I set a few easily seen traps and miscalculated at the very end missing the back row mate if I took the Knight. But there wouldn't have been any real hope even if the back rank mate wasn't available. My opponent wound up tying for second, not losing a game and gaining over 100 ratings point. A nice weekend of work, but I still think in the postmortem he underestimated White's attacking chances after the sac.
Comments and opinions on the sac would be welcome.
