About the only thing wrong with BGB is VERY pessimistic backgame evaluations.

In Response To: Here's the position (Frank Berger)

Unfortunately, it is a Whopper to pass this as the cubeful take equity is a bit less than -.9 !

XBG used to have similar issues with backgame evaluations but I think it is improved now. I do recall given this exact position to Xavier and maybe he used it for training. Anyhow, we'll see how XBG and others do with another basic simple well timed backgame tomorrow.

Frank, if BGB can improve it's evaluation of backgames, you'll have a better product since I fear that the cube errors will matter and that fear of backgames may cause it to play too safely.
