In Response To: 13 off, should I have cubed a roll earlier? (neilkaz)

With Perry being able to handle most 6's by not closing me out, I was pretty sure to not recube at this score. He'd played this endgame very well so far and I was sure he wasn't passing.

The score (after 0 games) is: Perry G 1, neilkaz 4 (match to 9 points)

Move number 2: neilkaz on roll, cube decision?

Perry G	61
neilkaz	26
Position ID: 7W4XAAABAAACAA Match ID: cAkgARAAIAAA
