Red Army vs. Spartans results
First of all, this was not the best way of playing the Modern -- this is the passive kind that I see all the time on Internet chess -- Black tries to play "solid," and plays e6, d6, puts his Knights on e7 and d7, and fianchettos both Bishops. But, speaking from personal experience, this approach simply doesn't work -- I have won countless blitz games simply by being patient and then opening up the position when Black is helpless against the tactical mayhem that follows. There are three active ways of playing the Modern:
1. Play an early ...Bg4 and ...Nc6, exchange the Bishop for the Knight on f3 early, and pressure the pawn on d4. We won a vote chess game with this variation.
2. Try to improve on the King's Indian by playing ...e5 and ...f5 before bringing out the King Knight.
3. Play ...c5 and then trade off Bishop for Knight on e3, crippling Whites Pawns and then seeking to control the e4 square.
I suggest you work out these three lines for yourself and figure out what you're comfortable playing.
But that was not the reason Black lost this game, thanks to White's 11th move. 11. Nh2?! was passive and allowed Black to equalize; White should have simply moved the Bishop to d3 where it would have been on a more active square, then bring the Rooks out.
On move 16, Black made a mistake that should have lost. 16...Qe7 should have lost to the pin move 17. Nd5, which would have lost the e6 pawn since the Queen had to go back to d8. After White failed to take advantage of Black's lapse, Black made a nice move in 18...h5!, killing White's pressure on the e6 pawn and ensuring at least equality.
On move 20, Black made a pawn break that was actually pretty interesting. The problem was that he could have captured the f-pawn for free. Sometimes it happens -- it doesn't occur to people that 1900 players make mistakes as well. White gets the pawn back with 21. Bxh5, only to have Black's queen come into the game with 21...Qg5 with tempo.
Black is still OK, but fell victim to routine thinking on move 21. Around 99% of the time, moves like 21...dxe5?? are automatic. But not this time -- Black ignored a pin that cost him the game. 21...Rxf4 would have held the balance because after 22. exd6, Black had 22...Bd4+ and Qxd6. This is the sort of thing that separates the men from the boys -- the strong players are the ones who are able to think outside the box and see the 1% positions when moves like ...dxe5 are losing moves.
We finally get on the board against the Spartans.
First of all, Karpov's namesake comes through in his first game against uuffoo:
But White had to follow up energetically, and failed to do so. Best would have been 9. Re1 O-O 10. Nxe5, when Black has dubious compensation for the missing pawn. That was a direct consequence of his third move, which set him back in development.
But from moves 9-17, Black plays excellent chess as he punishes White's premature Bishop pin by driving it back and establishing a bind on the King side. This bind is what will win the game for him, though not without a lot of twists and turns.
On move 18, Black starts to dither -- first, he locks his Queen Rook in with 18...Rfb8, allowing White to grab a pawn as compensation -- had Black played the correct 18...Rab8, that would not have happened because he can simply regain it with ...Rxb2. The difference is that after ...Rfb8, the King Rook has to guard the Queen Rook which is still on a8. But once he moved it there, he should have left it there -- Black has fair compensation for the pawn after 20...Be7 21. Qxf6 Bxf6 22. b3.
White tried for too much with 23. Qxc7?!, which allows Black some serious counterplay. Not only does he still have his blockade on the King side, his Bishop is able to support it with the pin on f2. Therefore, he did not have to fear the loss of a second pawn with 25...Bb6! 26. Qxe5 Qxe5 27. Nxe5, because his Rook dominates the 7th rank after 27...Rc2.
After missing that promising pawn sacrifice, Black was worse; White could have played 29. Nc6, which would have killed Black's counterplay and boxed in his Rooks. But his 29. Nf3? was the beginning of the end as his Knight was no match for the onrushing Black pawns. His best chance for a draw was to bail out with 31. Bxf4 gxf3 32. gxf3, but after hesitating once (31...Bf7?), Black rushes in with his pawns and wins a Rook and the game.
There was nothing wrong with 9...Qf6 and 10...Qg6 (as I thought during the game) because Black has to castle Queenside to avoid White's planned King-side onrush. The real error comes with 11...Qh5, after which the Queen becomes a target and Black must lose material. 11...f6 would have left him with a bad but tenable position as he would have created a flight square for his Queen and completed his development with 12...Nge7.
The second blown chance was when he played 21. Bxa6? Instead, he could have played 21. Qxe4, pinning the Knight and setting up a double attack. Black has to move his Knight to b4 or the Queen or Knight will drop. Then, White plays 22. Qg4, when both the Knight and g7 pawn are hanging. After 22...Nd5 23. Qxg7, White is much better since there is no secure place for Black to put his King.
The third mistake and losing move was 23. gxf3?? 99 times out of 100, that is a routine recapture. But in this case, the Bishop on a6 is hanging. Therefore, White had to throw in the check with 23. Bb5+. Then, he has time to capture the Queen and enter a better ending.
