In Response To: 1&3 Backgame #2 (Ian Dunstan)

The only conclusion I'd draw from this rollout is that breaking the midpoint is probably not the right idea.

		White is Player 2 score: 0 pip: 136 Unlimited Game Jacoby pip: 232 score: 0 Blue is Player 1
XGID=-a--A-B-B---dB---cBcbbC-C-:1:1:1:21:0:0:1:0:10
