1.d4 d5 2.Nf3 Nf6 3.g3 Bf5 4.Bg2 e6 5.O-O h6 6.a3 {c5 is by far the most popular move here. (RJ)} Nbd7 7.Nc3 c6 8.Ne5 {Taking it right out of book. Perhaps Kevin intended resolving the doubling of his e pawns by a subsequent e4. (RJ)} Nxe5 9.dxe5 Nd7 10.f4 Bc5+ 11.Kh1 h5 {I couldn't resist this. The White king looks to me to be very vulnerable. Both my programs pick h5. (RJ)} 12.b4 Be7 13.e4! {Best (RJ)} Bg4 14.Bf3 Bh3 {Given that this only has any point if followed up by the dubious h4, better would be 14........Bxf3. 15. Qxf3  h4. (RJ)} 15.Rf2 h4?! {Both my engines recommend this. However, interestingly, after White's next move, the stronger program changes its mind and gives White an edge. As I took my hand off the pawn I, too late, saw g4. (RJ)} 16.g4! {The explanation for Stockfish 7 changing its tune is probably it sees that Black's bishop is in trouble. I immediately felt my whole game plan now changed to the task of saving it. Incidentally,
 any attack Black may have had has disappeared. (RJ)} a5! {Best. Not with the idea of winning the b pawn, but to get Black's King's bishop to c5, where it can take the White knight if it goes to g1 to attack the bishop. Nevertheless, both engines give White an advantage of about .8 now.(RJ)} 17.exd5? cxd5 18.bxa5? {Be3 (RJ)} Bc5? {But the immediate Qxa5, attacking the white knight, is better. White now has the edge again. (RJ)} 19.Rd2! {Aiming to get at its prey on h3 via d3. (RJ)} Qxa5 20.Rd3 f5 {With the aim of getting a knight for the bishop after d4. (RJ)} 21.exf6 Nxf6 22.Be2 {g5 was even stronger (RJ).} d4 23.Rxh3 dxc3 24.Qd3! {Very strong. Aiming for g6. (RJ)} Kf7 {Qb6 is better. (RJ)} 25.f5 Rad8? {Qa6. (RJ)} 26.fxe6+ Ke7 27.Qg6 Kxe6 28.Bc4+ {Crushing. g5 was also pretty good. A nice, sharp game by Kevin after an aborted early attack by Black.  Kevin is hard to stop when he gets open lines and can exploit the dynamic possibilities in a position. It was a little comfort to me that the key losing move - 15.....h5 is recommended by my quite strong engines, which change their minds after they saw White's reply!(RJ)} {#r}
