Test your chess: Reitstein problem 193


White to play and win


M Hennings v W Berson 1987



A nice puzzle. After seeing that 1 Qa4 or 1 Ra3 are too slow, and similarly that 1 Rd4 doesn't do anything, I switched to making 1 Na7! work.


The first point is that 1…Ka7 2 Qa4+ Kb8 3 Ra3 the game is over.

Or, if 1…Qa5, 2 Ra3 Qc5 3 Qa4 Qc5 4 Nc6+ Kc8 5 Nd4 + –

So black's best is to try to prolong the game with 1…Rc7 2 Nc7 Qc7 3 Qa4 and the N escapes, or if 3…Qb6 4 Ra3, when since Rc8 is impossible (the Na7 looks at c8) then white will play c3, pushing the Nd4 away, and then Nb5, and will regroup and win.
