1/2 nl at a small casino, mostly locals. Game is super loose with lots of straddling and limping.

Villain: Old white guy, a regular. TP but is willing to gamble as shown in the two hands below. Also mostly a tournament player.

Relavent hands:
V limps in MP in a straddle pot, young Asian nit to his left with only 30bb raises to $25, folded back to V who shoves. Nit calls with KK. V has AJs and sucks out.

V limps again, this time with AdKd and just calls the button raise of $25. Button bets $30, V x/r ai. Button only had $100 to start hand, calls with JT.

Hero??

The first hand I put him on is AKs. I think if he has a set he will raise the flop for protection. KK and TT also unlikely since he didn't raise pre and I have blockers. Could have QJs ? AK is the only hand that made sense given previous history. The raise was also so big it looked like he was trying to protect his hand, but then why no raise on flop?

I think you have to call him.

Yeah I think this is a pretty easy call. You didn't raise pre and you're play on the flop and turn doesn't scream two pair, I could see him making this moving especially with AKs. No draws have gotten there just yet.

There's no made flushes or draws. Given the history, you have to call.

Did we double straddle?
Super -EV...

And screw that rake if you're paying 7 at $40...

Flop and turn both seem a bit small, but call it off once he shoves.

Fold pre

Super duper fistpump snap call. Reads kind of matter here with regarding whether I high five the dealer or just kind of shrug call. How loose is he pre? 63s in his range? How about T6s? From your hand histories though, I'm loving this spot:

1. He plays draws aggressively, and there's a lot of them out there. QJs, 45s, other pair + FD combos.
2. The hand started with 34bb effective. Top 2 is the nuts.

Bet a bit more OTT so that the river is a more comfortable shove. We be playin for stacks here yo.

Don't double straddle. Bet bigger on turn, always bet bigger on super draw heavy boards, sizing of 75-100 is fine imo. As played it's a call, if he has a set well that's just variance bud.

I think the two relevant hands makes him seem looser than he is. Another reg at the table said V's AJ call was unusual for him. As I said, he is a tight passive player. He would limp but mostly with premium hands.

Given that, I don't think he can ever have 45s, 63s, T6s or other small connectors/FD. I think his entire range is AKs, QJs, 66, TT, and KK. That would give me about 45% equity so a call would be right. But after those two hands he really tightened up and he didn't seem like the type of player to risk a lot of money on a pure draw.
If we take QJs out of his range, it drops to less than 30% equity. I'm calling $250 to win ~$450, so almost 2:1, not enough to call. QJs might be in his range but I think he has AK of spades way more.

I would fold preflop.

As played:
I would call for two reason

1. Based on the information you gave us about villian (mostly tourney player and TPTK is a good hand in tourney), as stated earlier, he does have some gamble in him.

2. If my plan preflop was to to take a chance and get into this OOP with this horrible hand, get lucky, and flop a straight or top two, I am betting every step of the way and am ecstatic that someone decided to go all in.

If he turns over trips or a straight draw and hits it, then next time, I will know not to get involved OOP with this weak of a hand!

If anyone was wondering, I did call and he turned over TT.
Also for clarification, I was in the double straddle (I know, bad!) and checked my option after V limped. If he had raised I would've insta mucked.
