Chuck's 22 DMP roll revisited

Posted By: Timothy Chow
Date: Saturday, 12 December 2009, at 9:33 p.m.

A little while ago, Chuck Bower posted a position with 22 to play at DMP. I thought I would try rolling out the same position for money. I was not surprised to see my play of 11/9(2) 6/4(2) being ranked high for money, but I was somewhat surprised to see how strong 24/20 6/4(2) continued to be for money. I suppose Blue's strong front position compared with White's very weak board is a big factor

Below are the rollouts, first with the cube in the center, and then with Blue owning the cube.
