Test your chess: Reitstein problem 83

White to play and win

AN Rubinsztein v RT Spencer 1964

Solution

I am not sure if Purdy's maxims apply in the endgame, but of course they can be help. Here, with the passed d pawn, 1 Bg5+! was immediately obvious to me, deflecting the King. The bishop is poisoned, if it captured the d pawn advances, but after 1…Kf7 this still happens, 2 d7, and the pawn promotes.
