Maciol-Gormally, Canterbury, British Championship 2010, round one, position after 31....Rf8-e8.
White, who is outgraded by 240 points, is winning. Indeed, the game lasts only one more move. White made his 32nd move - and then resigned.
My attention was drawn to the position by a comment - don't click on the link yet! - on the English Chess Forum, from Alex Holowczak, that White's 32nd
was probably the worst move on the board.Try finding it yourself before you look. But, you know, he's right. It was.
