This was a game that I was playing against GNU a couple of months ago. At the time I played 7/5(2) 3/1*(2). When I went back to look at the position again recently, I couldn't remember what I had played and I decided that either 13/11(2) 8/4 or 8/4 7/5(2) was preferable. The rollout favors 8/4 7/5(2). Attacking isn't that bad a plan and definitely wins more gammons, but since Blue has escaped everything and has a substantial race lead (and White's forward position is pretty strong), there's a lot to be said for just bringing everything home safely and attacking later if it can be done so with no risk.
In Peever's position we still had a straggler and our opponent had lots of good rolls; here we afford to bide our time.
