It’s Your Move: daily chess puzzle # 81

White to play and win

(A tough one)

Teschner v Hecht, Berlin 1964

Solution

This one took me a while, since whilst some moves are obvious, there is one key, hidden, point to find. Purdy’s concept of jump-biffs would help.

Firstly, 1 gf has to be played, else Black can close the position, gain space, and has the advantage. 1…Qf6 is forced, when 2 de Be5 3 Nd5!!, or 2 Nd5!! cd 3 de is equivalent:

and white ends a pawn up, with the safer king.

Black could try to mix things, playing (1 gf) 1…e4 2 Qb3! putting maximum strain on Black, and after 2…Qf6[] 3 Rg7+ Kg7[] 4 Qb7:

4..Rd8 5 Ne5 Be5 6 de Qe5 and White is better, with Houdini saying winning, though at my level there is easy scope to lose.
