Hi all,

can someone please explain me the following numbers (a shorter rollout makes it obvious that the bug isn't restricted to the standard errors):

posID: a9skAAzHeTsAAA matchID: MBkgAlAACAAA

Cube analysis
Rollout cubeless equity +0.566 (Money: +0.566)

Cubeful equities:
1. No double +1.010
2. Double, take +1.079 ( +0.070)
3. Double, pass +1.000 ( -0.010)
Proper cube action: Too good to double, pass (12.3%)
Rollout details:
Centered 1-cube:
0.779 0.016 0.000 - 0.221 0.008 0.000 CL +0.566 CF +1.010
[0.019 0.001 0.000 - 0.019 0.000 0.000 CL 0.014 CF 0.442]
Player ace owns 2-cube:
0.783 0.015 0.000 - 0.217 0.007 0.000 CL +1.198 CF +1.079
[0.001 0.001 0.000 - 0.001 0.000 0.000 CL 0.004 CF 0.005]
Full cubeful rollout with var.redn.
1296 games, Mersenne Twister dice gen. with seed -715772175 and
quasi-random dice
Play: world class 2-ply cubeful prune [world class]
keep the first 0 0-ply moves and up to 8 more moves within equity 0.16
Skip pruning for 1-ply moves.
Cube: 2-ply cubeful prune [world class]

Why is the standard error for Centered 1-cube (cubefull) at 0.442?

Ciao
