In Response To: 3 pt match cube action (neilkaz)

OTB noting my opp's cubeless and gammonless TP AtS is 30% rather than 25% for money, I was happy to cube this. My opp passed quickly and for a moment I wondered if I should've cubed last roll as I'd lost my market. Then I came to my senses since no matter how many G's I win, my opp always has a take here if he can win 40% of the time. Clearly I felt he can win at least 35% so I then was happy to win a point.

In reality and as Weaver showed posting a similar position, my position isn't as good as I'd thought. I do have only 9 checkers in the zone and the 8 pt and 2 pt don't work that well together and I have 3 checkers back. My opp survives often enough to win at about 40% of the time.
