OTB & RO

In Response To: Recube action? (John O'Hagan)

XG recubed me in this position. Pass makes the score 11a-7a with ~30% MWC using Neil's Numbers. If I take and auto recube to 16 before my next roll, my takepoint is then this same 30%. Auto recubing is premature of course so the true takepoint is a bit less than this.

Can I win close to 30%? I broke Blue's rolls into 5 categories: 1) 6s. 2) Board closers. 3) 55. 4) Anything else and fan. 5) Anything else and I roll a deuce. I came up with about 30% wins in these categories and took. The XG RO agrees with R/T.

Recubing does reduce Blue's gammon value but I think it's correct because the bad sequences (3 & 5 above) are pretty bad for Blue. 3 is obviously bad since Blue has to give up his 6-point but 5 is even worse: 62 & 22 enter and make a 6 prime while 52 & 42 enter and hit loose on the 2-point.
