In Response To: Rollout - Really? (David Montgomery)

I did a shorter rollout and it gave 9/3 9/4 as probably better than 18/7 but clearly not best. It loses a few gammons with no compensation.

If fact, the blot on the 23 point is totally useless for now when the action is in the outfield, and when the 13 and 15 points are cleared White is likely to be well stocked with spares.

1. Rollout 23/18 9/3 Eq.: -0.385

0.381 0.026 0.001 - 0.619 0.020 0.001 CL -0.227 CF -0.385

2. Rollout 18/7 Eq.: -0.475 ( -0.090)

0.370 0.030 0.000 - 0.630 0.056 0.002 CL -0.288 CF -0.475

5. Rollout 9/4 9/3 Eq.: -0.444 ( -0.059)

0.379 0.043 0.000 - 0.621 0.069 0.004 CL -0.271 CF -0.444
