In Response To: DMP 11 (Chase)

Over the board, I played the "automatic" 8/7(2)* 6/5(2)*. XGR++ dinged me for it, preferring 8/7 6/5(3)*. The difference was only 0.002, but the top choice surprised me enough to run a quick and dirty 2ply/3ply rollout, which had XG's odd-looking play better by 0.011. So I fired up a more robust rollout, then posted the position here to see if QF was enough to put 8/7 6/5(3)* on anyone else's radar. The rollout is too close to call, and I'll not burn any more cycles on it, but I still find the result interesting. A NMS rollout, included below for comparison, is more definitive and prefers the "default" play.
