You'll need to feed the whole game history therefore instead of just the position to probably get the same move(of course it is also possible you won't ever get the same move because of different hash entries). Anyway it's needless to talk about ...f3(=) because it draws like most other moves too, what every better player can see(read my other post). Regrettably the original poster omitted the pgn, thus we cannot see where the _real_ blunder was, if it hadn't lost on time at all. Guenther
