It’s Your Move: daily chess puzzle # 96

Black to play and win

Uhlmann v Yanofsky, Tel Aviv 1964

Solution

This one took me a good while- half a dog walk- before it dawned on me that I was missing something simple. 1…Be5! is a natural biff, aiming also at 2 Bf4 mate, but it took me a while to see that after 2 Rd7+[] Kany 3 f4[] that after the pawn is captured, Black can take the now LPDO Bb6. I had missed that the B was a LPDO once the rook has moved.

In Purdy's terms, examine all biffs and looking for pins, nets and ties, is the key here. The White King is in s net, and the White Rook is tied to defending the Bb6.
