This game, won by Janowski years ago, ended with a pretty quick mate because his opponent’s reply to his first move was not the best defensive move. If he had played the best defensive move, it would have taken Janowski a lot longer. I worked that out, too, and it led to mate by virtue of a very extended and instructive kingside attack. It’s a long line, but worth playing over.

The short mate was pretty, but don’t forget to go through what might have been. There a loads of side variations to that, but I put just the best main one in. 1.Bxg6 Qxh4 1...Qxg6 2.Rxg6+ Nxg6 3.Qg5 Rf7 4.h4 Kh8 5.h5 Nf8 6.g4 Bd7 7.Rg1 Ra3 8.Qf4 Ne6 9.Qb8+ Nf8 10.Qg3 Ra8 11.g5 Re8 12.Qc7 Be6 13.Qf4 Nd7 14.Rb1 Nf8 15.Kg2 Bc8 16.g6 hxg6 17.hxg6 Rd7 18.Rh1+ Kg8 19.f7+ Kg7 20.fxe8N+ Kg8 21.Rh8+ Kxh8 22.Qxf8# 2.Bf7+ Kxf7 3.Rg7+ Ke6 4.Re7#
