FWIW, here's XG's rollout. I can't imagine that it's best to do anything other than make the full prime. XG says that play is a quintuple whopper. Does anyone think XG gets this right?

BTW, I didn't bother to fully roll out all the options.

		White is Player 2 score: 0 pip: 59 Unlimited Game Jacoby Beaver pip: 184 score: 0 Blue is Player 1
