In Response To: Money Cube #2 (Stick)

Knowing White's back checkers split would have an enormous effect I thought this cube would be clear but still wasn't worried about the take and would have snatched it up pre rollout. Still against my nature to give up something with this much play left in it. I'm probably going to play this position out a bit until GNU shows me its high win % and crushing gammon wins.

Move number 3: gnubg on roll, cube decision?
