Test your chess: Reitstein problem 145

Another fine example of the necessity to examine all checks, captures and threats.

White to play and win

AA Ponelis v K Morris 1963

Reitstein’s rubric says that black played the prosaic 1…Bf2 and won, and asks his reader to look for something more telling. With this clue, 1…Bf3+!! has to be tried (a Purdy player would look at it, following examine all biffs) with their not being many lines.

Firstly, 1 Rf3 loses the LPDO queen by 1…Qe1: again, a Purdy player would note in the initial position that white’s Q is a LPDO and that there is a jump biff Qh4-e1 (so the Rf2 is pinned).

Next, 1 Kf3 Qh3+ 2 Ng3[] Nd4 mate. Or 1 Kg1 Qh3, and white is helpless with the Rf2 being pinned; and K elsewhere leaves the Rf2 en prise.
