Black has an annoying initiative on the queenside.} 17.c4 Qa5 18.b3 Nd4 19.Qd1 {The queen sortie to h5 didn't really do very much except waste two moves. However, my opponent now thought for a long time over his next move and was getting short of time.} f5 20.Bd3 fxe4 {This brings my bishop into the game.} (20...f4 21.Nd5 f3 {This looked dangerous, maybe what my opponent was thinking about.}) 21.Bxe4 Ra7 {Preventing the perpetual.} (21...Rab8 22.Qh5 g6 (22...h6 23.Qg6 Rf6 24.Qh7+ Kf7 25.Nd5) 23.Bxg6 hxg6 24.Qxg6+ {draw by perpetual}) 22.Nc2 Rf4 23.f3 Nxc2+ 24.Qxc2 Qc5 {My opponent offers a sacrifice of his h-pawn. I declined it after some thought, a decision which puzzled him, but I wanted to keep the game quiet and try and build up against d6. Psychologically this decision, along with his time trouble, may have contributed to his later mistakes.} 25.Qf2 Qc7 26.Rd1 a5 27.Rxd6 {Winning a key pawn.} Bf7 28.Qd2 g6 {A blunder. I had already been thinking of playing g3, and now my opponent unprotects f6 and loses the exchange.} 29.g3 Rxe4+ 30.fxe4 a4 31.O-O axb3 32.axb3 Qc5+ 33.Kh1 Ra3 {The position was lost already, but my opponent effectively resigned by playing this move. It allows mate in 7.} 34.Rd8+ Kg7 35.Qd7 {A nice easy win to start the day. This was the double-round day, so this gave me time to go and eat lunch and rest before the afternoon round.} (35.h5 {This is the mating line. The threat is h6 mate.} gxh5 36.Qg5+ Bg6 37.Rd7+ Qe7 38.Rxe7+ Kg8 39.Rf8+ Kxf8 40.Qf6+ Kg8 41.Qg7#) {#r} 1-0
