GM Gawain C B Maroroa Jones (2616) mated GM Sergei Tiviakov (2653) in 37 moves in round 2 of the Pall Mall Masters blitz in London, with 5 seconds on the clock.
It turned on 33...Ng8, played with 1:06 left. Stockfish wanted 33...Qb6. Before the knight move it counted only a small edge for White (+0.50); after it, a win (+6.12). 34.Qh5+ came straight back, then 35.Qh7+, 36.g4 and 37.Qh8#.
Maroroa Jones played the last two moves with 7 and then 5 seconds on the clock.
Go back to 33...Ng8 and see how the queen got in. Then play the position on against the engine.
