In Response To: More Pitt DMP Play (Stick)

More DMP play which seems to fascinate me of late. Another thing I've already mentioned that fascinated me this weekend were the amount of overlooked plays. I was watching this match and kibitzing with Perry Gartner. We both preferred 23/18(2) 8/3(2) and set up the position shortly after the match (along with a few others). Later that night I fed the position to GNU to see that not only the player in question, Chuck, had not even considered what is possibly the best play, but afterwards myself and Perry didn't even consider it!?

It's much easier to see all the candidate plays when it's presented as a quiz problem, esp. if you read others' responses first, but OtB plays sometimes elude us, perhaps another factor why the bots will remain stronger than the humans.

The score (after 0 games) is: user 0, gnubg 0 (match to 1 point, post-Crawford play)
