Black to play and win
Black played 1..Bh2!, met by 2 c4; what next?
PTR Hodges v BE Siegheim 1906
Following Purdy, ignore the threat, and think what you would do if the threat could not possibly be executed. So, examine all biffs, 1…Qb2, 1….Nf2 and 1…Qf3!, and see that the latter one leads after 2 gf to 2…Bh3 mate.
