Here’s a Stonewall Attack for your enjoyment. 1.d4 d5 2.e3 e6 3.Bd3 Nf6 4.Nd2 Bd6 5.f4 Nc6 6.c3 Ne7 7.Nh3 0–0 8.0–0 Bd7 9.e4 dxe4 10.Nxe4 Ng6 11.Nxf6+ gxf6 12.f5 exf5 13.Bxf5 Bxf5 14.Rxf5 Kh8 15.Qh5 Rg8 and now our diagram.

A post WWII amateur game. An instructive miniature. Armitage - Reese (C80)UK Army v Navy, 1946. 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0–0 Nxe4 6.Re1 (Better is 6.d4, but this is tricky)6...Nc5 7.Nc3 (Better is 7.Bxc6) 7...Nxa4 8.Nxe5 Be7 9.Nd5 0–0? (Now would be a good time to bring the knight back so it can go to e6 to block the e-file. 9....

This is a win with one decisive move at the outset that is best.

This requires calculation. Be careful!
