In Response To: 53P-21S-65 and 53P-41S-65 (Taper_Mike)

For 53P-44B-65, the position that started this thread, we now have three rollouts confirming that splitting is narrowly correct in a choice that is tied according the Ballard-Weaver scale.

53P-44B-65

[S R17]	'<=5	Dmitriy
[S R2]	"<=20	Nack
[S R4.2]	"<=62	Mike

My rollout for 53P-21S-65, Dmitriy’s 1st variant, is given below. Running is best by a hair. Essentially, running and splitting are tied. We still do not have a rollout for 53P-41S-65, Dmitriy’s 2nd variant. If you have a rollout of that one, or any of the other positions in this thread, by all means, please post them to this thread (and/or send them to me). Thanks to all. Mike
