In Response To: ROLLOUT 1-4-5 backgame - Hit one, hit two, hit none? (ah_clem)

It's not fair to extrapolate AtS or $ game rollout win % and say flatly that the play that won the most games there would also be the dmp play. It often is, of course, but the computer is not playing the checkers out the entire game like it's dmp so it's no surprise that it doesn't always hold true.

While if I really cared what was ultimately best I'd do a rollout with higher settings due to the potential complexity of the position but I don't care so here's a regular settings dmp rollout.

		White is Player 2 score: 0 pip: 187 1 point match pip: 127 score: 0 Blue is Player 1
