Simon Thorhallsson from Iceland (black) had fought for a long time against Collin Colbow from Germany, without much hope.
White just made the seemingly decisive 71.Rg6-g5. The threat is Rf3-f8 with mate. But Simon found the last chance – he sacrificed the queen with 71…Qh4†! and whites only options was 72.Kxh4 and stalemate!
