Bxa6 Rxa6 15.Qe2 Qd5 16.Qc2 h6 17.Nd2 Rc8 18.Rfd1 Ra7 19.Nc4 N8d7 { 20.Bxh6! is a surprising way for white to win a pawn because if 20...gxh6 21.Ne3 traps the queen.} 20.Nxb6 $6 {White swaps off his best piece and brings black's knight to a better square.} 20...Nxb6 21.Rd3 Bf8 {This move for white and the next one seem to lose time - better to play 21...Rac7 immediately.} 22.Rcd1 Kh8 23.Nc1 Rac7 24.Ne2 Qe4 25.f3 {25.R3d2 offering to simplify is a better way to limit black's advantage.} 25...Qh7 26.Qb2 Nd5 27.Bf2 Be7 28.g3 Qf5 29.Kg2 h5 {The computer is keen on ...c5 bringing black's pieces to life on this move and for a few subsequent moves. Instead black tries to weaken white's kingside first.} 30.R1d2 Kg8 31.h3 Qg6 32.Kh2 Qf5 33.g4 $6 {Don't open the position on the side where you are weaker is a good rule to remember!} 33...hxg4 34.hxg4 Qh7+ 35.Kg2 Qg6 36. Bg3 Bg5 37.f4 Qe4+ 38.Rf3 Ne3+ 39.Kf2 Nxg4+ {White has won a pawn and still has a strong attack.} 40.Kg2 Bh6 {40....Be7, aiming to reroute the bishop to the g1-a7 diagonal, is better.} 41.Ng1 Ne3+ 42.Kf2 Nd5 43.Re2 Qf5 44.Kg2 c5 $1 {Finally the breakthrough!} 45.dxc5 Rxc5 46.Qd4 Rc2 47. Ref2 Rxf2+ 48.Rxf2 Rc2 49.Ne2 g6 $1 {A good move to activate the bishop.} 50.Kf3 Bf8 {50....Qh5 wins a piece immediately.} 51.Qa7 Qd3+ 52.Kg4 Rxe2 53.Rf3 Qf5+ {54.Kh4 Qh5 is mate.} 0-1
