The 32S-51S-43Z-43 position of this thread is the fourth entry below ("21pt"); the rest are variants. The first column tells us how White's anchor has been altered, with everything else remaining the same.
24pt [@ H24]
23pt [@ H75]
22pt [@ H4]
21pt [H @49]
20pt [H @18]
18pt [H @110]
The XG2 rollout results (5k trials, 3-ply checker with roller cube) are nacbrac'ed in the second column, and detailed below. It's interesting to ponder the fluctuating margins as White's anchor becomes more advanced.
