It is a failing of mine that I get too confident too quickly when a position looks promising. I should know by know, after countless hard-fought games of chess, that things can change very quickly.} Nbd7 13.O-O O-O 14.Nd2 b6 15.c4 Ne8 16.Be4 g6 17.g4 {This move greatly weakens my kingside. I should have been patient and played more slowly with something like 17.g3.} (17.Bh6 f5 18.Bxf8 Bxf8 19.Bf3 e4 20.Bxe4 fxe4 21.Qxe4) 17...Bg5 18.Nf3 (18.f4 exf4 19.Bxf4 {Black's king is clearly safer here than White's king.}) 18...Bxe3 19.Qxe3 Ng7 20.Qh6 {I thought about this move for ages, convinced that I had a wining attack after 20...f5.
