{584MB, Fritz11.ctg} 1.c4 Nf6 2.Nc3 e5 3.g3 d6 4.Bg2 g6 5.d3 Bg7 6.Nf3 O-O 7.O-O Nc6 8.a3 h6 9.Bd2 a5 10.Rb1 Be6 11.b4 axb4 12.axb4 e4 13.Ne1 {(BvR) Seems too passive to me. Black not only opens up the long black bishop diagonal,but also has the option to dominate the e-file later.} exd3 14.exd3 Bg4 15.Qc1 Kh7 16.b5 Nd4 17.f3 Be6 18.Kh1 Nd7 {(BvR) Perhaps 18...d5! was stronger, but the text move looked more natural to me.} 19.f4 Nc5 20.Be3 Qc8 {(BvR) Not the best move,but I got confused by the various possibilities. Decided to focus on swapping the white bishops, leaving white's king more vulnerable for an attack. However, 20...Re8, pushing along the e-file,probably would have been the preferred option after all.} 21.Nd5 Bh3 {(BvR) 21...Re8 , threatening Nb3 would have been better} 22.Rf2 Bxg2+ 23.Kxg2 Re8! 24.b6? Ncb3 {(BvR) It took me more than 30 minutes to decide:I knew that Nb3 the crucial move, but which one;preceeded by c6 or after white's queen move? My thoughts went in circles, and I moved one of the horses to b3 at random (my score-sheet shows only 24..Nb3, but I could have played 24...Neb3 instead of 24...Ncb3). It didn't matter,as Kevin responded with Rxb3?} 25.Rxb3?
