I b/f turn here for sure and b/f river if called and checked to.

I don't see why we'd ever not want to go for 3 streets if value here. Only flushes really beat us and he'll likely make it very obvious he has one in this spot. We really don't need to pot control or induce bluffs on this turn because his range is pretty much polarized to a few hands that beat us (flushes/sets), but mostly Qs and weakers hands with some showdown value that he'll likely continue to pay us off with.

I think checking this turn not only gives a free card that could kill our action or our hand, but misses out on value vs a range we are still way ahead and will pay us off quite often.

The beauty of b/f at these stakes is that noone ever really c/r's the turn as a bluff because they see our line as strong. Therefore, it should in theory be very easy to cut our losses and fold if we are raised at any point here.
