Last time Paul did not play 2 up an made a mistake, this time he plays 2 up and makes mistake too. The difference is that here he has a good plan B, while the previous leaving a blot on the 9 point with a 34 was unnecessary in view of the two-up candidate-move. |

Black does not need to hit a blot in the outfield, but he needs a robust position. The more checkers on the 8 and 6 points, the more robust the position. Points will come. |

Snowie 3 ply evaluation seems to be wrong here. It says 13/4(4) is best, but a mini rollout of the resulting positions after the actual 6/4(2)* 13/11(2) and the Snowie 14/11(4) turns to 0.070 in favor of the actual move. A lot. Black has lots of approaches here. He can play for undoubled gammon if white fans. He can double white out in a simple racing position. He can double white in for a gammon match winner. Positions where it is often difficult to conceive the doubling window. In fact the undoubled gammon for black is not such a big miss (1 away 6 away crawford would be a near gin). The 9-to-5 approach is to play for undoubled gammon and reconsider in the final racing phase. |
