It’s Your Move: daily chess puzzle #234

Black to play and win

Hennings v Barczay, Sarajevo 1969

Solution

Not to hard today, perhaps; but it took me a long time; most of a twenty minute dog walk before the solution came to me, and then I felt I should have solved it earlier.

1…Qh5+! (which I suspect I saw immediately, but equally immediately rejected it) and if 2 Nh5 gf+ 3 ef d5! (the point) prevents the Pf7 from queening, so that the Pd3 wins the game.

I think I fell into the typical trap of rejecting moves without thinking: a natural human process; once again, Purdy’s examine all biffs would have helped solve it faster.
