Friday chess puzzle 16: the solution

van Scheltinga vs Stahlberg, Chess 1950

Last week's Friday chess puzzle from Van Scheltinga vs Stahlberg, Amsterdam 1950, generated a lot of interest.

White has just played Bd5, apparently catching Black's knight on e6 in a pair of deadly pins, but Stahlberg found a forced win for Black:

Most of you spotted the first couple of moves without problem:

1 ... Rxd5; 2 Rxd5 Qb7

and then after 3 Qg2, Black doesn't play 3 ... Nf4?? which loses to 4 Rd8!, but instead wins by a lovely queen manouevre:

3 Qg2 Qb1+; 4 Qg1 Qe4+; 5 Qg2 Qxg2+; 6 Kxg2 Nf4+ winning the rook, and Black emerges a piece up.

Congratulations to Paul Devisser, Chris Wardle, and 'averageplayer', amongst others.
