Resigning in error

Anyone who plays chess will know the feeling of reaching a winning position, only to screw it up and to lose the game instead. So far so normal, and the cliché about ‘snatching defeat from the jaws of victory’ can apply to any sport. But chess offers a far more piquant anguish, unavailable in most other endeavours. Even among chess players, only a tiny minority will experience it. Directly resigning in a winning position – that is the stuff of nightmares. It sounds ridiculous – why would you ever do that? All it takes is to overlook one crucial resource, and it happened last week to one of the best in the world.

    The diagram position below is taken from an online game played in the Champions Chess Tour. Nakamura, rook for bishop ahead, has just offered an exchange of rooks on the g-file.

Champions Chess Tour Knockout, May 2025

Carlsen plays his trump card, clearly planned a few moves earlier: 32…Bg4! From the video stream, it is evident that Nakamura has not seen that coming, and 33 Rxg4 Qxf3+ is catastrophic. He holds his head, gestures in despair and resigns 25 seconds later. Just after the game finishes, Nakamura checks the game with his computer, only to be confronted with the brutal truth that his position was actually winning. The cold-blooded 33 Rfg3!! wins, since 33…Bxh5 34 Rxg8 is mate. 33…Rg5 is a better try, but 34 Qe8+ Rg8 35 Qf7 should win. Nakamura has to smile, no doubt sensing the absurdity of his error.

That lucky break handed Carlsen a 3-1 victory over Nakamura, and he went on to dominate the final match against Maxime Vachier-Lagrave, winning 2.5-0.5. The first game was particularly elegant.
