(29) Orton,P (1602) - Van Kemenade,J (1709) [B07] Dyfed closed (4), 31.10.2011 [Kemenade] 1.e4 d6 2.d4 Nf6 3.Nc3 c6 4.Nf3 Qc7 5.h3 Nbd7 [5...e5 avoids the next move] 6.Bf4 [6.Be3 Abhishek-Dzhumaev, Commonwealth Ch 2010,1-0] 6...e5 7.Bh2 Be7 8.Bd3 [8.Qd2 Gehrmann-Tuertmann,Ger ch Seniors 2008,1/2-1/2] 8...h6 9.Qd2 a6 10.a4 Nh7 11.0-0 Ng5 12.Nxg5 hxg5 13.Be2 f6 [13...exd4 14.Qxd4 Ne5= ] 14.d5 c5 [14...a5!? ] 15.a5 Fritz13 considers this a Wh win, but the Bl position is still resilient 15...Nf8 16.Na4 Ng6 17.Nb6 Rb8 18.Qd1 Nf4 19.Bg4 Bxg4 20.Qxg4 Rh4 21.Qf3 Kf7 22.Bxf4 gxf4 23.Ra3 Rbh8 24.Qe2 g5 25.f3 Bd8 26.Kf2 Kg6 27.Nc4 Wh still has a space advantage, and a superior N to Bl's bad B, but it is not at all clear how Wh could break in. The only attempt is to play b4 at some stage, but this may also liberate the Bl pieces. 1/2-1/2
