Your sixth roll cube position (shown in the left-hand diagram above, which btw can also arise via 54S-11e-F-65S-F-C) looks like a powerful double. With an 11-pip lead, stronger board, and White already on the bar, there must be many MLS (market-losing sequences).

I offer the commonly arising (fifth roll) variant in the right-hand diagram, which has the identical pipcount with inferior checker placement (essentially 8/6 instead of 13/11). Is it a double?

For your follow-up position diagrammed below, where Blue has tacked on 52D to his already strong position, it appears that one of the many MLS has occurred. Double/Pass.
