In Response To: Evaluations (Mislav Radica)

Long GnuBg rollout agree with XG Roller but XBG 3ply evaluations is almost same with it's 3ply rollout (although not the longest one). Anyway, such swing with 0.150 equity from GnuBG 2ply evaluation and 2/2 ply rollout is realy something! Btw, what is XG roller? Truncated rollout?

The score (after 0 games) is: Woolsey 1, Readers 2 (match to 5 points)

Move number 3: Readers to play 65
