Interesting endgame

[Alex Holowczak]

This game happened online, and this stage was reached: 8/7p/pK3p2/6k1/P5P1/2P4P/7b/8 b - - 2 50

The person who did it was disappointed to only draw with black, but after playing through it afterwards, we still can't find the win for white.

Obvious tries included winning the pawns on h3/g4 and trying to sack the Bishop for a pawn, but white always seemed to have enough compensation to steal a draw.

Is there a win for black here?

[James Coleman]

If one does exist, I can't see one! I thought ...h5 might work but The best I got for Black was a drawn Q+B v Q ending.

[Nick Murphy]

Rybka 4 with the Turbobases (all 5 and some 6 piece tablebases) can't find one.

It's moved away from h5 and now suggests Kf4 - but still no win...
