I have spent some time analyzing the position are you sure it is a win for black?

I guess I am getting horrible at chess

Depth 34 was reffering to the engine analysys. I'm not too bad at chess (it depends upon your standards!), but I haven't put a parcell of brain cell into the position. When I got your reply, I swith away from FireBird To StockFish 1.6.2:

[d]5rk1/5p1p/6p1/p2P1bP1/2p5/q1P1Q3/6BP/4R1K1 w - - 0 1

00:59:26.7 -0,88 24 1781521146 Qd4 a4 d6 Be6 Bc6 Rd8 d7 Qe7 h4

For now it looks like white is down a pawn (depth 25).

Edit: Down half a pawn: 01:29:05.5 -0,56 25 2665558461 Qd4 a4 d6 Be6 Bc6 Rd8 d7 Qe7 h4 a3 Re2 Rb8 Kf2 Qd8 Kg3 Qf8 Kf3 Rd8 Kg3 h5 Kf2 Kh7 Bb5 Qh8 Qxh8+ Kxh8 Bxc4 Rxd7 Bxe6 fxe6 Ra2 Ra7

As Albert said, It appears drawing. I haven't invested time in it but from first impressions I too think it's drawing.

Albert, you fell for his trap by responding, and now I too have fallen... :oops:

I take it that Rybka 4 has not been released yet.

I take it you don't see 28 zillion threads screaming Rybka 4 is out.
