About 50 left out of 165 starting field with top 21 paying. Lot's of good regs left but plenty of weak players and fish also. I had only been at this table for 1 level having just been moved here. Was short stacked but doubled up when I jammed 19bbs over a LAG's open, and have been on a rush of hands recently and have taken down 3-4 pots in the past 1.5 orbits.

500/1000 - 100 ante, 9 handed

Hero 48k stack opens to 2600 from UTG+2 with AKcc.
Villain 70-80k 3 bets to 7k from the HJ
Hero?

Reads on villain. He doubled recently after a big spew where he got in with a bad flush draw and gut shot on the turn. He also has been limping and flatting raises from various positions. Seems loose, that one hand I saw led me to believe he's prone to spazzing. I have no info on his 3-betting range.

I decided to flat and take a flop. I'm not looking to get it in this deep so 4-betting I would have to fold to 5-bet shove. I'm confident enough post flop that I don't wanna do that. Thoughts on pre-flop?

Flop: As 4s 2h

I check (I think this is standard?)
Villain bets 7k with little hesitation
Hero?

I think check-call is probably standard? He 3-bet pre so his range shouldn't hit this board very often in a way that beats us.

I decided to check raise to 14k to try and get it in verses a random spazz hand of his. FWIW I actually meant to make it 18k but misclicked! I'm thinking we could get it in here vs any big draw or weaker ace (AQ, AJ) possibly even QQ or KK.

Villain shoves. I call because that was the plan and we're really only beat by one combo. He shows up with the one combo of AA and I'm busted in a 100k pot. Sick cooler just about any way I play it. Anyone with thoughts on how to play differently not looking at results? I hate going broke with 50bbs like this because it's such a valuable stack with so many weak players. I was peaking and on a rush and all of a sudden walking away wondering what just happened.
