It's such a weird line for the HJ to take that I really don't have a good handle on what his range is.  I have to imagine that the HJ's range is mostly hands that he was originally trying to trap with.  AK, AA, KQ, maybe some two pair combos.  I think KK also makes sense.

The BTN can be pretty wide here I would think--raising a lot of his value hands (though he would perhaps sometimes flat sets) and also a decent number of semi bluffs and even perhaps hands like A9ss.

Given that range, is it better to simply call and try to get more money in on the turn?  Or is it better to just ship the flop?

My thinking at the time was that the BTN is unlikely to continue to barrel his airy hands into two players, so because it looks strong no matter what I do it's better to just ship it in on the flop and try to get the HJ to call with his "trappy" range that we are crushing.

Thoughts?
