Position of the Day 07-19-25 - Lift? - Rollout

In Response To: Position of the Day 07-19-25 - Lift? (Stick)

Both who responded went with the lift so we didn't really discuss which non lifting play would be correct but it's probably obvious to most of you that /14 is best as it leaves [66 44 33] as covers instead of just [66 55]. Also playing I imagine a minor roll is a few return shots from the bar if we are hit with [62] and just the checker being closer in general so that next turn we are more likely to get it into direct range.

With that out of the way a good question becomes what's the cube action after either play + fan? Those rollouts are below.

XGR+ and weaker all thought this was a clear take. XGR++ agreed with the full rollout.
