Test your chess: Reitstein problem 223
White to play and win
Slightly cooked, so worth spending some time on. Reitstein's rubric was 'If, as White, you had reached this favourable position you would soon realise that if given the chance your opponent could return some material by 1…Ne5 for counter play. So you have to force home your advantage without delay, as Kirby did.'
KF Kirby v M Bleiden 1949
Solution
Reitstein's hint is a big steer to 1 Rf7, and this is indeed the move which was played. The game continued 1..Qc6 2 Raf1 Qh6 3 Qf5 1-0. However, isn't 1…Ne5! a natural try, since whilst the Qc7 is LPDO, so is the Qd3? Stockfish confirmed that the position is level: 2 Qh7+ Kh7 3 Rc7 cd 4 cd Nc4.
So strange that Reitstein didn't mention it, and also strange that black didn't play it, though of course it might have been a time trouble position.
Stockfish has a nice move following the above position, which I will post separately in a moment.
So, since I saw 1…Ne5, it wasn't hard to see 1 Qf5 or 1Rf5! which is the move I chose, and is also the engine's choice. One nice point is that 1 Rf5 Kg7 2 Rf7+!!
2…Kf7 3 Qh7+ Ke8 (say) 4 Raf1 and the fact that the Qc7 is LPDO and there is a jump biff Qf7-c7 in the position means it is game over.



Am I missing something? In your first solution diagram, Black has just played 4…Ne5-c4, so it is White’s move. But in the following article, the same position is given but with Black to move (and the suggestion Na5-c6).
I’m wondering if what you and Stockfish were considering was the continuation 4…Ne5-c6 5.Ra1-f1. Or …
Jonathan: I have corrected the diagram in the following post. Thank you for pointing out the error.
