Anyone who still has tiger 12.0 should be able to confirm this. I have >gambit2.0 and tiger 14.0, but as ive posted before i prefer tiger12.0. What I am trying to ask is this: 1. from the original position, does CT understand that trading all the rooks is bad? IE a 5-6 ply search should let it see the rooks coming off. And after that PV/score is displayed, does it show white is winning? 2. After playing the moves that trade the rooks off, there are no pieces left. It is pretty easy to search to 20 plies here, and that is more than enough to see that white queenside majority turning into a white outside passed pawn. Does it realize the outside passer is winning? If it doesn't realize white is winning after searching just deeply enough to see the pieces coming off, then it is going to have trouble in these kinds of endings, which are pretty common. If it does realize white is winning in case 2, that means it probably understands the outside passer, or at least it knows that one side having a passer is probably winning. The more interesting question is "does it understand that the white majority is _also_ winning if there are no pieces left, because the majority will turn into a distant passer later in the game"???
