Yo, so this is a hand from the MSPT 1100$ main a few weeks ago. I don't think we are supposed to say peoples names actually but the dude has won this and many other big events in minnesota. (His name rhymes with stu, Im pretty sure a few of you know him) Anyways, dude is a 3/4/5 betting machine with polarized ranges and im wondering how you extract the most money of out a player like this… 

SO, I have literally played 1 hand in this tournament and i just opened (2.25x from button and the blinds folded) the blinds are at like 100/200. I have a 20k and some change stack villain in question is at about 13.5 maybe less. 

He opens the pot for 550 utg+2, the guy next to me in MP calls I look at Red AA and raise to 1575 folds back to villain who makes it 2775 mp guy folds I call.

Flop is 10 8 7 with 2 spades he bets out 1,475 I raise to 3k and he folds.

The questions i have here are both p/f and flip 

Are you ever 5 betting here pre? 

On the flip do you just flat or is a raise good here? 

I mean the guys range mostly consists of big pairs here 88+ and suited and connected cards I would say 67o+ 34s+ (i seen a showdown where he had 35s in pot he 3 bet already) So its very possible he has some of that and is just throwing out some type of blocking bet and if he has an overpair to the board i gotta think im stacking off here right? 

But i loose all opportunity for him to barrel so its kind of a weird spot. Or else im a total fish… either way
