In Response To: Hmmm.. I thought this was one of the more interesting decisions I had all weekend *NM* (neilkaz)

OTB I cubed this as a 2 is crushing and may lead to a G and if I miss a probably get another shot and there may be some sequences where Perry rolls something really sick at some point and I am losing the match. GNU 2 ply hates my double, and 4 play didn't like it either and even 3 ply doesn't care for it.

Perry liked my cube, but he scooped of course and after missed this shot and a later 2, I was recubed for match. I'll post that interesting and mathematically oriented position at the top of the main list.

The score (after 0 games) is: Perry Gartner 1, neilkaz 0 (match to 9 points)

Move number 11: neilkaz on roll, cube decision?

Perry Gartner	58
neilkaz	106
