In Response To: LV Round #5 Play #2 (Matt Cohn-Geier)

I was not afraid of the blot left behind on 21/13 8/4(2). What I didn't like was that it didn't address the timing issue. I would rather bring all 15 of my checkers bearing against his 5 point. However, Kit will be leaving me a shot if he throws a 6, making the 17 point gives him a bit more time to throw doubles, and it fails to improve my board. A 4 point board will be a weapon in the future.

GNU again charged me with a significant error, rollout reduces it, but convinces me that I made the wrong play.

The score (after 4 games) is: Kit Woolsey 2, Matt Cohn-Geier 5 (match to 15 points)

Move number 17: Matt Cohn-Geier to play 44

Kit Woolsey	112
Matt Cohn-Geier	141
