Hello guys (and dolls),

i recently analyse a lot of my games with gnubg, usually i understand his moves and decisions, but now he "said" something very strange.

In the following almost similar positions (sorry for the text jumps, i dont know how to get them straight, just enter the position ID in gnubg and you will see the correct position) he has different decisions, the only difference is that in the second position there is an x-man on the bar, and strangely enough he consideres this position better for x. Who can explain me why??
