In Response To: Vegas SJ - Munitz Cube (Stick)

I was questioning myself a bit by like the 5th game where I was trailing 6-2 (and quite happy about not being down 10-2). My cubes kept feeling so borderline but every one of them I thought was an actual cube. Here I figured that at an even score I would have held off but even being down a couple of points would turn this into a cube.

The score (after 0 games) is: gnubg 4, user 2 (match to 15 points)

Move number 3: user on roll, cube decision?

gnubg	126
user	139
Position ID: zJ2DAyCY2ybgAA Match ID: cAngAUAAEAAA
