1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.f4 Nf6 5.Nf3 a6 {O-O is more usual (RJ)} 6.a4 {To prevent b5 and create a space for the white-squared bishop, so it can stay on the a2-g8 diagonal. The most popular move on Chessbase (RJ)} O-O 7.Bc4 {Not favoured by my engines or Chessbase. (RJ). Bd4 and Be2 are the most popular moves. (RJ)} Nbd7? {Nxe4! was much better, according to the engines and Chessbase.(RJ) We are now out of all book lines. (RJ)} 8.O-O c5 9.a5? {e5 (RJ)} b6? {In post-game analysis we felt that cd was necessary here. The engines agree. Black is now already in trouble. (RJ)} 10.e5 dxe5 {Ng5 was a little better. (RJ)} 11.dxe5 Ng4 12.Ng5 b5? {Nh6 (RJ)} 13.Bd5 {Better is Bxf7! (RJ)} Ra7 14.Qxg4 b4 {Best} 15.Qh4 {One of those happy positions where everything falls into place. Moving away from the discovered attack by the bishop; it just happens that doing so gains a tempo by threatening mate. (RJ)} h6 16.Nxf7! Rxf7 17.Bxf7+ {f5! is best. (RJ} Kxf7 18.e6+ Kxe6 19.Re1+?! {Having drawn the black king out into the open, the engines say the best move is 19.f5! If 19....gf  Stockfish 7 gives the surrealistic, incredibly complex line  20. Be3!  Kf7  21. Rad1 Qf8  22. Qc4ch  Kg6  23. Nd5  Ne5  24. Qc5  Rd7  25. Nf4ch  Kf7  26. Nd3,  - pretty unlikely to be played by 2 humans(RJ)} Kf7 20.Ne4 Qc7 {Nf6 is better (RJ)} 21.f5 g5? {Nf8.(RJ)} 22.Bxg5! {Taking advantage of the weakness of Black on e6. If Black recaptures, White's knight will control the game from there after the check. (RJ)} Bb7 23.Bxh6 Bxh6 24.Qh5+ {Unnecessary finessing. (RJ)} Kg8 25.Qxh6? {Too timid. 25. Qg6! Bg7  26. Ng5 (RJ)} Bxe4? {Qe5 (RJ)} 26.Rxe4 Nf6 27.Qg6+ Kf8 28.Rh4 Ng8 29.Rh8 {#r}
