Hero ???

Not much information on UTG player, but the button has been super aggressive. And by aggressive I mean calling with a wide variety of holdings and raising with top pair, strong draws, etc. He's also aggressive by his betting actions as well. He's constantly slamming chips onto the felt and whenever he folds he tends to hit some portion of the dealer (face, hand, etc.)

As for the hand, I expect a lot of 9x, 7x to continue, but two pairs and sets to raise on the flop. Is this a spot to just get it in or check to see what my opponents do?

Don't like both of them calling on the flop but given those stack sizes I can't see folding either. With an over pair and an SPR of 3 on the flop there just isn't much that can be done.

If you are confident button will bluff/semi-bluff if checked too then checking is OK. Mostly I would rather just shove. You don't want to give the T9/87 type hands a free card. If one of them has a set your losing your stack anyways.

Yes to the all in. You have less than a pot sized bet left. Make them pay to see the river card. If you check and V bets $400, are you going to fold? That answer should be no, so you might as well make the bet yourself.

I think you nailed the continuing and raising range. My vote is to GII.

GII is the only correct play unless you are a supernit

GII super standard here. You will run into it a fair amount of the time but it is bleeding $ not to jam.
