Here is the "agg" (bot aggregate) of four positions:

52D-32 [D S12 Z43]
54D-32 [D S5 Z23]
32D-32 [D=Z S14]
43D-32 [Z D12 S52]

Key: D = Down (13/11 13/10), S = Split (24/21 13/11), Z = reverse split (24/22 13/10). Error sizes are in thousandths; for example, "[D S12 Z43]" means that D is best, S is -.012 and Z is -.043.

Currently, for 52D-32, we have Snowie [D S8] 31k and GnuBG [D S24] 5k only. The latter rollout needs extending and we do not yet have XG data. For more info on the other three positions, click on the links provided.

In the progression of the four positions below (upper left, upper right, lower left, lower right), D starts out as best with Z being clearly wrong. As the opponent's blots get closer and/or increase in number, Z (reverse split) gains until it pulls even with D in the third position and overtakes it in the fourth:

52D-32 [D S12 Z43]

54D-32 [D S5 Z23]

32D-32 [D=Z S14]

43D-32 [Z D12 S52]

Again, here is a summary of the progression:

52D-32 [D S12 Z43]
54D-32 [D S5 Z23]
32D-32 [D=Z S14]
43D-32 [Z D12 S52]
