IMHO you miss that Yace has only 50.26% totally against Aristarch with White, thus 49.61% is only marginally off. I see much more suspicious stats for it (only selected chunks > 150 games): *Yace as White* (avg. 50.26%) AXX: +289 =185 -363 ( 45.58% in 837 games) A1X: +81 =59 -108 ( 44.56% in 248 games) *Yace as Black* (avg. 41.20% A01: +59 =130 -185 ( 33.16% in 374 games) B1X: +36 =31 -101 ( 30.65% in 168 games) BXX: +171 =126 -309 ( 38.61% in 606 games) I guess one has to look closer into the exact lines of those openings.
