White to play and win

Szabo -Polgar, Budapest 1968

Solution

(firstly, not one of the sisters, but Istvan Polgar; also, Megabase says 1968 but Teschner says 1969; I have gone with Chessbase).

White needs to find a way to fork/discover, and the biff 1 Bd7! is the trick.

Then Black can either play on the exchange down, or capture, 1…Nd7, when 2 Qc8! diverts the Queen:2…Qc8 3 Ne7+ Kg7 4 Nc8 and White emerges a clean exchange up.
