"J Healy V T Donohue, London - 1976. The game is hardly out of the opening, but white (to move) already has a promising attack. How did he force a quick and brilliant win?"
Following on from my original post nearly a month ago, today we have another John Healy problem. It's a Leonard Barden chess column, I'm guessing from the Evening Standard, which I found reproduced at thegrassarena.net.
