I hope that with Cannes/WSOB/Bob Koca hype that people still want to see bg problems posted, these got very few views in relation to anything else. I'll post another set but if ppl aren't interested in them I'd rather know and not waste my time posting them.

Here OtB I thought rather quickly that it was D/P after either play and was hoping to buy a free roll by not exposing my jugular. It didn't work, but again, it didn't matter to me, it was D/P either way so might as well try for the free roll. The problem is GNU evaluates the upcoming T/P decision as a rather large take on 2ply giving me this big error. It corrects itself in the rollout but I'm stuck with an error I think is unfair, for lack of a better term.

The score (after 3 games) is: Neil_Kazaross 3, Stick_Rice 1 (match to 13 points)

Move number 22: Stick_Rice to play 25
