How do we feel about hero's 3! on the flop? Obviously we have a ton of equity, but do we want to be isolating ourselves against the Btn at this point?

My guess is it depends on how often we expect MP1/MP2 to take 2 to the face.

button's range is very wide here, I have great equity vs. him and would have been happy for the other 2 to fold for 2 more, but if they call that's not too bad either, no one liked their hand enough to raise the first time around.

3B! runs the risk of shutting out you customers which is a bad idea. value wise in LLHE.

Also leading at this flop is questionable. you would much rather check raise/ lead or flat and semibluff/ or raise a pat. however your range is wide so you must be willing to play against players who think that you may be protecting a pair w/ a good kicker.

as played you should probably just call the raise and bet any rag on the river.

getting flushed over isn't all the uncommon it happens. hopefully you can minimize the damage and still get some value from a goof who turned or flopped a set and decided to now go off.
