Daily chess puzzle

Today’s problem is from 38 years ago, when I was at Cambridge University. I have been visiting my alma mater this week.

As has been my custom on this blog for a while, I adopt the style of only saying which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.

Black to play

Allan Beardsworth v Nick Wall, Cambridgeshire Championships, 6/12/1981

Solution

1 Rg4! and White wins; alas, I played 1 Rf4, but Black didn’t play the only move, 1…Rd1+, winning, instead playing 1…Be3:

and now 2 Qh7+! Kh7[] 3 Rh4 mate.

FEN

6rk/5p1p/1pp2PpQ/p2rq1P1/P3p3/1P5P/2n1N1R1/5RK1 w – – 0 31
