8/8/8/8/Q2B3k/5pp1/4K3/7q w - - 0 9
White : Ke2, Qa4, Bd4
Black : Kh4, Qh1, f3,g3
White to play
I tested this endgame in a module match Fritz10 - Rybka and on hand.
Every time Fritz10 wins with Black and draws with White.
It is very difficult for a human being to prove that Black wins.
But 90% I believe it.
What do you think about this endgame ?

With W to play, 1. Bd4-e3+ is mate in 4, isn't it? Is there a typo in
your position?
Black to play, 1...Qh1-e4+ seems to win,if you avoid the tricks.

No
It is White to play but the White King e2 is in check by the pawn f3 so 1.
Bd4-e3+ is illegal !
