What's the best move?

White to move.

Position is after 31...exf3+. The game is between F. Niro & D. Gregoryev, Eastern Open, Washington D.C., 1996.

Your choices are:
a. gxf3
b. Kxf3
c. other

Answer and analysis:
Best is b. 32.Kxf3 with a dead draw after 32...h5 33.Kf4 g6 34.h3 Re7 35.Kg5 Kf7 36.g4 (1/2-1/2).

a. 32.gxf3? loses after 32...Re7+. For example, 33.Kd3 g5 34.Ra2 Kf7 35.Kc3 h5 36.Kb4 g4 37.fxg4 hxg4 38.Rc2 f4 39.Rg2 f3 40.Rxg4 f2 41.Rf4+ Ke8, etc. (0-1)

c. Any other move will lose because once the king steps aside, White has the choice of f2 or fxg2. One or the other will win easily in every situation.
