Nimzo style

As promised, this week a victory by chess aficionado Dominic Lawson, former editor of The Spectator. Dominic’s distinguished opponent was Peter Lee, who has been British champion in both chess and bridge — a unique achievement I believe. The following is a fine Nimzowitschian game, not least in the amazing versatility of the Black knights. Notes based on those supplied by the winner.

15 … Ng4! 16 Bxc7 16 fxg4 Bxe5 much better for Black. 16 … Nxe3 17 Re1 Nxf1 18 Bd6 0-0 19 Rxe7 Bf6 20 Rxb7? Best was probably 20 Re1 though after 20 … b4! the best White can get is a rook and rook versus rook, bishop and bishop ending which must be winning for Black.
