XG weaknesses?

In Response To: XG weaknesses? (Timothy Chow)

It has a slight bias in favor of slotting in the opening.

I've heard that about rollouts based on gnubg 2-ply, but not about gnubg 2-ply evals themselves. I haven't studied that at all, but on the two money game examples that I just tested, 2-ply does not seem to have a bias in favor of slotting. They were 21 ($ ahead by 0.003 according to gnubg 2-ply) and 51S-21 (gnubg 2-ply plays 24/21, $ is behind by 0.027).

In fact, I thought that part of the pro-slotting bias of 2-ply based rollouts might be due to an anti-slotting bias of the 2-ply evals.
