How do you weigh the benefits of set hunting here? I just don't know how to factor in the BB's call. Easy fold if the BB doesn't call since the CO is so short. Since effective stack size is now my stack size, does that change things (even if I was at a full 100BB stack?)? I'm thinking no since we are less likely to double through the BB since he just called and may very well be set hunting himself and fold on the flop.

I'm fairly new to the table, so no read on either villain in this hand yet, though they seem to be loose in the 27-32% range over less than 30 hands.
