In Response To: Another routine boring 3 pt match holding game cube (neilkaz)

GNU gets this wrong on 2 and 4 ply. Snowie gets it wrong even after a mini-rollout. XG does a decent job here with only 3 ply getting it wrong and other plies and XG roller getting it right.

Clear error to not cube here and big mistake to drop, noting my lack of spare on the 8 pt can be uncomfortable.

The score (after 0 games) is: Opp 0, neilkaz 1 (match to 3 points)

Move number 3: neilkaz on roll, cube decision?

Pip counts: Opp 121, neilkaz 102
