50.69% was with 2ply evaluations, it will take some time to reproduce 
the experiment :-).

In the output with --q1 :

# X - 504  O - 496 (50.40+%) (262 121 117)

The 50.4% gross result is unbiased, right ? But estimating the variance is 
not clear to me. Compared to the plain random dice there must be a 
additional term close to (121+117)/500, something like that.
