In Response To: xG evals + rollouts + quirk (Robert-Jan Veldhuizen (Zorba))

That's a lot of numbers to swallow, so I made a quick overview below. xG is definitely NOT a dressed-up GnuBG, as it behaves clearly differently among different settings.

xG evaluations 3/4/5-ply and xG roller all close to each other. Pretty close to GnuBG's 2-ply evaluation too. They all show a bigger pass than GnuBG's rollout.

The xG rollouts on various settings (xG ply-notation) show an interesting picture:

1-ply checker play rollouts: closer to too good, even bigger pass, but only slightly higher cubeless.

2-ply checker play rollouts: lower cubeless, ND close to evaluations, much smaller pass, very close to GnuBG's rollout result(!)

3-ply checker play: this is unexpected, not sure what to think of it. Cubeless much higher, ND much higher, DT way higher. Double Whopper to take, and borderline Too Good.

BTW: I turned Jacoby off, as I always do for money. Certainly for rollouts I think it gives better and more interesting results. This could be important for the ND value.
