White to move
It is checkmate in two, but White played nine more moves before losing on time. White had 3.8 seconds: enough for two good moves. Black had 6.3 seconds remaining, and was down to 0.3 when White's time expired. Clearly White outplayed Black, but White was found wanting in basic checkmate skills.
After 52.Qg5 Kc5, White missed a checkmate in one. A no point through the last nine moves was White more than three moves from checkmate.
