I thought it's not possible yet - I was wrong, the computer much prefers Black here.} 18.exd5 (18.e5 d4 {counter attack!} 19.exf6 Nxf6 20.Ne5 Bxg2 21.Kxg2 dxe3 22.Qxe3 Nd7 23.Qg3 b5 24.cxb5 axb5 25.Nxb5? (25.Rbc1 Nxe5 26.fxe5 b4) 25...Qb7+! {These are the usual tricks that are involved in the b5 break. Black's pieces suddenly eye the king with nasty double attacks.}) 18...exd5 19.cxd5 Nxd5 20.Nxd5 Bxd5 {with a great position}) 18.Rbd1 Bc6 19.a3 {One of the kibitzers later wondered about this move. "You should play at the side where you have the advantage." Houdini likes it though so there was some deeper purpose.} (19.h4 b5 20.cxb5 axb5 21.a3 d5 {These pawn breaks are all very annoying for White!}) 19...b5 (19...Nhf8) 20.g5 {interesting play} (20.cxb5 axb5 21.d4 {It's important to understand that in this position cxd4 is BAD.}) 20...h5? {Well, I really need to understand these pawn storms better. } (20...b4 21.axb4 cxb4 22.Nb1 hxg5 23.fxg5 Nc5 24.Nbd2 e5! {very complicated position. e5 looks best but it's dangerous for Black now.} 25.h4 Bb7 26.Bh3 Bc8 27.Bf5 Nf8 28.h5 Nfe6 29.h6 Nf4) 21.b4 (21.cxb5 axb5 22.d4 b4 (22...cxd4 23.Nxd4 e5 24.Nxc6 Qxc6 25.Qxb5 Qxb5 26.Nxb5 {and White is much better.}) 23.axb4 cxb4 24.d5) 21...bxc4 22.dxc4 g6 23.h4 Nb6 24.Rb1 Bf8 {with the idea to get the bishop to g7} (24...Nf8 25.Nd2 Nfd7 {hmm, this looks better!}) 25.Qd3 d5 {an almost instant reaction} 26.exd5 exd5 27.cxd5 Nxd5 28.Nxd5 Bxd5 29.Qc3 Rc8 (29...c4 {This was surely an idea although I didn't want to defend the pawn for the rest of the game. On the other hand this looks better than what happened in the game!} 30.Ne5 (30.Rbd1 Bg7 31.Ne5 Bxg2 32.Kxg2 Nf8) 30...Bxg2 31.Kxg2 Bg7 {This is a very tactical position!} 32.Rbd1! {only move} (32.Rbc1??

My idea here was to rather increase the pressure and get the queen to another diagonale. After winning the pawn I thought White will just push the c-pawn and it will be very dangerous for me.} 39.Rxf4 Qxf4 40.c7 (40.Nf3 Qg4+ 41.Kf2 Ne6 42.Qe5 Nf4 43.Rc3 Qg2+ 44.Ke3 Ne6) 40...Qg4+ 41.Kf1 Qxh4 {hmm, it looks as if Black has enough time here. The c-pawn is no immediate threat.}) 39.Ne2 Ne6 {The poor knight finally comes to a good square again.} 40.Qf6?? {I think my opponent underestimated the danger. Of course it's tempting to put the queen there but his pieces are too uncoordinated and there is no real attack.} Rxe2 {Surprised looks at the faces of the kibitzers - this move was unexpected and turns the game.} (40...Rd2 {Even better than the text move. We looked at this with a couple of other players. Black has huge pressure and White is busted.} 41.Kf1 (41.f5 Rexe2 42.Rxe2 Rxe2+ 43.Kf3 Qh2 44.Qxf7+ Kxf7 45.fxe6+ Kxe6 46.Rf1 Qg2+ 47.Kf4 Qg4#) 41...Rdxe2 42.Rxe2 Rxf4+) 41.Rxe2 Nxf4+ 42.Kf3 (42.Kf2 Nxe2 43.Qxd8+ Qxd8 44.c7 Qc8 45.Kxe2) (42.Kf1 Nxe2) 42...Nxe2 43.Kxe2 Qh2+ 44.Qf2 {This was probably the best try but it's still lost.} (44.Kf1 Qh3+ (44...Qh1+ 45.Kf2 (45.Ke2 Qg2+ 46.Qf2 Re8+ 47.Kd3 Qxf2 48.Kc4 Qf4+ 49.Kc5 Re5+ 50.Kd6 Qd4+ 51.Kc7 Re7+ 52.Kc8 Qa7 53.c7 Qa8#)) 45.Kg1 Qg3+ 46.Kf1 Rd2 {and soon with mate}) 44...Rd2+ 45.Kxd2 Qxf2+ 46.Kd3 Qg3+ 47.Kd2 Qc7 {Simple plan. Blockade the pawn, then create a free pawn on the king side.} 48.Rc4 Kf8 49.Kd3 Ke7 50.Kd4 Kd6? {this doesn't really work, the king has to change places with the queen.} 51.Kd3 Ke7 52.Ke4 Kd8 53.a4 Qe7+ 54.Kd5 Kc7 55.Kd4 f6 56.gxf6 Qxf6+ 57.Kd3 g5 58.hxg5 Qxg5 59.Kc3 h4 60.Kb4 h3 61.Rc5 Qxc5+ {White resigns} 0-1
