In Response To: A more complicated backgame position to test yourself and BOTs (neilkaz)

Just not enough play to take this one. It seems GNU's eval is good here, how are other bots?

The score (after 0 games) is: opp 0, neilkaz 0

Move number 4: neilkaz on roll, cube decision?

Pip counts: opp 176, neilkaz 136
