In Response To: Position of the Day 08-28-25 - Rollout (Stick)

As I always wonder with positions that have the potential to be backgames or somewhat complicated, will a stronger rollout produce different results? The answers is almost always no. Not only in the ranking of plays but the absolute equity of the plays remains virtually the same. In short, it is rare we ever need to waste our time/our CPU cycles to do high level rollouts but we'll continue to do it anyway.

I stopped this rollout before it was anywhere near stat sig for which play is better because I only wanted to be sure it was in the ballpark of the regular rollout. It is so moving on...
