Stellar, you make some interesting points (as usual). Yet, it still seems to me that your approach (i.e., just calling the flop raise rather than 3-bet and lead the turn) is based on a few possibilities that are not especially likely.

Specifically:

(1) the chance that MP is slow-playing with a 10 or 88 in his hand;
(2) the chance that UTG will raise the turn with a worse hand, and make us fold incorrectly;
(3) the chance that MP will shed his loose/passive skin (and remember, OP said her was mostly passive both pre and post-flop) and try to represent trips on the turn.

Yes, one of these situations might occur, but I think it is more likely that they won't.
