[Event "BCC Championship"] [Site "Kevin's office"] [Date "2016.06.11"] [Round "7"] [White "Kevin Perrin"] [Black "Bas van Riel"] [Result "0-1"] [WhiteElo "1607"] [BlackElo "1884"] [ECO "B30"] [Opening "Sicilian: 2...Nc6 3.Nc3 Nf6"] 1.e4 c5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bc4 d6 5.h3 e6 6.O-O Be7 7.d4 cxd4 8.Nxd4 a6 9.Nxc6 bxc6 10.Bf4 d5 11.exd5 cxd5 12.Bd3 O-O 13.a3 Bb7 14.b4? {White is asking for trouble, as this weakens his queen side (BvR)} Rc8 15.Ne2 Nd7 16.Ng3 e5 17.Bc1 e4 18.Be2 Bf6 19.Ra2 Qc7 {Black's plan is to increase the pressure along the c-file, to reduce white's options of counter-play, and create trouble on the rook on a2 via d4 and Bd5. The plan is reasonable, but the execution is not flawless.BvR)} 20.Nf5 Nb6 21.Bg4? {When playing 20..Nb6, black miscalculated the possible and strong reply by white 21.Bb2 believing that 21...Qxc2?;22. Bxf6,Qxa2 would have won the exchange. In fact, white would win after 23.Nh6, gxh6;24.Bxc8 and black will be checkmated! In hindsight, I hope that I would have seen this continuation, and replied instead with 21...Bxb2; 22.Rxb2, g6 and 23..Rd8, still with very good chances (BvR)} Na4 22.Bd2 d4 {22...d4!? Perhaps 22..Qc4 would have been more direct but certainly more complicated (BvR)} 23.Nxd4 {Black perhaps could have tried 23.Ng3 with options of 23...e3 or Qc4 (BvR)} Bxd4 24.Bxc8 Rxc8 {Black now is winning with two bishops for a rook (BvR)} 25.c3 Nxc3 26.Bxc3 Qxc3 27.Ra1? Qxa1 28.Qxa1 Bxa1 29.Rxa1 Kf8 30.Kf1 Rc2 {#R} 0-1
