[Ovyron]

Rybka can't offer draw, it was the GUI.

[kgburcham]

I thought that is what I posted Uly.

[Ovyron]

But Rybka isn't asking the GUI for anything, the GUI decides to do it itself.

[kgburcham]

Ok Uly can't you see I am Tapping Out?

[Uri Blass]

It is clearly a search problem

Rybka with clear hash can see advantage for white and 51...Kf7 instead of 51...Kf8
