Cube Action AtS

My OTB approach for 4 or higher cubes when leading in such scores is to consider sending it if the take is in question or I know it is a pass. Otherwise, unless I know the % well, I do not want to give my opponent an easy 4 cube with strong 8 cube potential. Incorrect non- doubling can lose small equity while incorrect premature doubling can cost tons of equity.

In the specific position and score, I know that the TP for 100% efficiency (=live cube) is ~13%. The efficiency for the position at hand seems extremely high, so I would guess the effective TP to be ~14%. Looking at the position, we have a clear money pass, but without much calculation, I would guess that White has at least 15%, and probably more. Therefore, the take is so clear that I rather not send the cube. If Blue gets fortunate and gets a 6 prime, just enjoy the gammon leverage on the 2 cube and try to get a second checker.
