Engine: stockfish 8} 1.e4 h6 2.b3 e6 3.Bb2 b6 {Already an interesting pawn pattern} 4.Nf3 Rh7 5.d4 Be7 6.Bd3 Rh8 7.d5 Bf8 8.c4 Bb7 9.O-O Nf6 {It was about this point that I though if I could sac the knight on f7 after Ne5 but couldn't find anything.} 10.h3 {keeping the pesky knight out after a possible e5} Bc8 11.Nc3 {With the idea of bringing the knight to  the kingside} d6 12.e5 {Engine gives dxe6} dxe5 13.Nxe5 exd5 14.Re1 {+8 according to engine} Be7 {Blocks the discovered check and the possibility of winning the queen after sacrificing the knight and bishop} 15.cxd5 Kf8 16.Bc4 {Could have sacrificed the bishop on g6 winning a piece or exchange if taken
(engine gives +4.1)} Nbd7 {Harrison resigned almost immediately after playing this move as after Nc6, white will win the queen} 17.Nc6 {[Example]} Qe8 18.Rxe7 Qxe7 19.Nxe7 Kxe7 {White would have had a queen to a rook} {#r}
