32Z-64 [H R32 S40 P63]


Three alternatives (on 32Z-64)? Z seems unjustified, desu ne? I guess S, R, and P are all available; "I don't know what to do, so I'll shut my eyes and pretend it's the opening roll". But S looks too big, despite the 6-duplication, and I don't care to play behind White's split with P. That leaves R, which would be my second choice.

I really hope hitting is right.

Your prayers have been answered. I have two rollouts; both are 5k and the first isn't even with a live cube, but it's good nuf for guvmint work.

Snowie .. [H R38 S49 P66] 5k
GnuBG .. [H R26 S32 P60] 5k

Key: H = Hit (13/3*), R = Run (24/14), S = Split (24/18 13/9), P = Point (8/2 6/2), Z = reverse split (24/20 13/7). Error sizes are in thousandths. Number of trials ("k") is in thousands, rounded down. For example, [H R26...] 5k means that H is best, R is -.026, etc., after 5000+ trials.

It is instructive that for 32Z-64, P is fourth best and a blunder compared to H. Though it is "only" .031 behind R and .023 behind S, compare with 43S-64, which is diagrammed below and only two pips different, where (by bot aggregate) P is best and edges out R by .007 and S by .024.
