| White to move. |
White wins easily after 107.h6! Qd7 108.Qe5+ Kg8 109.Qg7+! Qxg7 110.hxg7 Kh7 111.Kh5! Kxg7 112.Kg5. Instead of that he made a natural-looking move:
107.g5?? The passers are marching together! Yet, this move is a terrible mistake as now the white king is too exposed and White no longer has the option of going into a pawn endgame with one pawn left.
107...Qd7 108.h6 Kg8 109.Kh5 Qf7+ 110.Qg6+

| Black to move. |
110...Kh8! 1/2-1/2 (because 111.Qxf7 is stalemate!)
What (many people) missed is that both players made an additional mistake – White could win by playing 110.g6!, while Black had to play 109...Qd1+! 110.Kg6 Qd6+ 111.Kf5 Qc5+ 112.Qe5 Qc2+ =.
