One of the tricks:
what's your output for white pawn on a5, black pawn on h2, black king
somewhere, say on c1 and the board is 8*8.
What will you output? What do you think about
1. a5-a6 h2-h1Q
2. a6-a7 Qh1-a8!

In fact, I have found out this trick.... Safe Bird (USU) 30 Oct 2002 15:33

Try to think about the position like
White pawn: c5
Black pawn: b6
Black king: a5
WHITE WINS (with c5-c6!)

White pawn: c5
Black pawn: b6
Black king: e5
WHITE WINS (with c5:b6!)

or

White pawn: c4
Black pawn: b5
Black king: a4
BLACK WINS

Aha, and don't forget about following:
White pawn: c4
Black pawn: c3
Black king: c2
WHITE WINS

White pawn: c5
Black pawn: c2
Black king: c3
WHITE WINS

More samples needed :-) ?

Aha, the last of them.... i get"BLACK WINS" Safe Bird (USU) 30 Oct 2002 15:40

In fact, I have found this kind of state, and wrote it on a paper. But I forget to put this kind of code into the program....:) Safe Bird (USU) 30 Oct 2002 15:42
