Two minute game, with eight second increments
I obviously didn't foresee Black's Rook sacrifice, after which it's mate-in-two, as follows:
a) 27.fxg3 Qxg3+ 28.Kh1 Qh2#
b) 27.Kh1 Rxh3+ 28.Kg2 Qh2#
c) 27.Kh2 Rg2+ 28.Kxg2 Qh2#
This opponent played a very good game. But I avenged myself in the re-match...
