This was a complex and interesting game, which Black did not deserve to lose. Learning when one has to stop trying to win a position is a very important and difficult lesson.

1.e4 c5 2.c3 d6 3.d4 Nf6 4.Bd3 Nc6 5.d5 Ne5 6.Bb5+ Bd7 7.Bxd7+ Qxd7 8.Bf4 8.f4 Ng6 9.Qe2 e6 offers Black counterplay, but White is OK. 8...Nxe4 9.Qe2 9.Bxe5 dxe5 10.Nf3 f6 (or the dynamic 0-0-0) is fine for Black. 9...Qf5 10.Bxe5 Qxe5 11.Qb5+ Kd8

White has gained a lot of space with his c and e pawns. Now he needs to consolidate those gains, and begin an attack on one flank. The queenside is a quicker target for attack, and black can quickly aim 4 pieces at the c5 pawn after ...b6. White should prepare b4.

14.Rfe1 [14.Rab1 or 14.Rfb1 prepare b4 directly. A tricky 14.a4 is even possible: 14...b6 15.b4! Qxb4 16.a5! traps the black queen.] f6 [ Much better is 14...b6 15.cxb6 axb6, when black has nearly even chances with further counterplay against the center based on ...c5.] 15.Bd3 [15.Qg6 is even stronger, leading with the queen and then lining up the bishop behind it.] Nf8 Inconsistent play. Black should take the e5 pawn, as his last moved indicated. 16.Ne2 b6 More important is blocking the weakened kingside by 16...f5. Black has more chances for this maneuver in next four moves. 17.Nf4 a6? [ Another inconsistent move as Black fails to use his pawn breaks. 17...bxc5 18.exf6 Bxf6 picks off a pawn, then White attacks 19.Nh5 with a complicated game.] 18.Ng6 White plays to trade off pieces defending opponents king. [18.b4 Qxb4 19.Rab1 Qa5 20.cxb6 with queenside play is an alternative. 20...Bb7] 18...Nxg6 [18...bxc5 19.Nxe7+ Rxe7 20.dxc5 favors White, but Black should play this way as he forces a favorable exchange while maintaining his kings defense.] 19.Bxg6 Rd8 20.Nh4? White has a good idea - moving his pieces closer to the black king. But he fails to take into account the discovered attack on this loose knight. [ stronger is 20.b4 Qxb4 21.Rab1 attacking safely on the queenside.] 20...Qb4 [20...f5! blocks the white bishop and threatens the h4 knight 21.Nf3 bxc5 and Black has a very reasonable game.] 21.Bh7+ Kf8 22.Qg6 [22.Ng6+ Kf7 23.Nxe7 Kxe7 24.Qg6 is quicker.] 22...bxc5 [22...Qxd4 is better but 23.Qh5 Bxc5 24.Ng6+ Ke8 25.Nh8+ Kd7 26.Qf7+ Be7 Black holds on but white has many attacking resources remaining, such as 27.Ng6 or 27.Rad1.] 23.Re3 Not worried about losing a few pawns on the queenside, White lifts his rook and keeps going after him on the kingside! [A good alternative goes 23.Qh5 Qxd4 24.Ng6+ Ke8 25.Bg8 a key maneuver which White uses in the game.] 23...Rd7 [23...Qxb2 24.Rae1 Qxd4 25.Rg3 Qxh4 26.Bg8 mates or wins queen.] 24.Rg3 [24.Nf5 Qxb2 25.Rae1] 24...Rb7 [24...Bd8 25.Qh5 Rda7 26.Ng6+ Ke8 27.Ne7+! g6 28.Nxg6 Rxh7 29.exf6 wins] 25.Bg8!!
