Nitty fold or correct thought process?

This hand has been playing on my mind a bit because I can’t work out if this is stupid or not.

Live cash game. £1/£1 blinds at local casino.

I’m not a regular player but I play a bit and I like to learn about the game.

9 man. Villain opens to £6 (pretty standard for the table) UTG+1, one caller in mid position, then folds round to me in the cut off.

The villain had been very quiet, not played many pots and had folded to 3 bets preflop a few times. The caller had been trying to see lots of flops, lots of calling preflop, so I had him as loose passive.

Villains stack was approx £130 when the hand started.

I had about £250.

I have AKo (suits aren’t important for the action)

3 bet to £20.

Blinds fold, villain calls, other caller folds.

The fact that the villain didn’t fold meant I put him on quite a strong starting hand, as he had folded to 3bets previously. So I’m thinking big aces (although I have blockers for this), pairs 8/9+ and maybe suited broadways. Don’t think his range consists of much else. I’m assuming he 4bets QQ+.

Flop comes A Q 9 on a rainbow.

Villain checks, I bet £30 into £48. I had not been throwing loads of chips around, the table had been quite loose aggressive in general and in those circumstances I generally tighten up a bit and try to value bet my hands.

At this point the villain shoves. £110 into £78.

This completely took me by surprise. Not too many decent draws out there (only J10) which seemed unlikely for him to call a 3bet out of position, based on his previous play.

I think for a while then fold. I just couldn’t see any hands I was beating at this point, I just convinced myself he had either flopped a set of 9s or AQ hit two pair. I couldn’t see him doing this with air, and the only hand I’m beating really is a weaker ace or chopping with AK.

I also have a general rule that I never go all in with one pair if raised, because you are usually behind.

The villain showed me AJ 🤦🏻*♂️.

Based on the stack sizes and the size of bet, mathematically I should be calling this I think. But in a vacuum, I think you are usually behind?

Or is this just a snap call? And I’m just a nit, that doesn’t know what he’s doing?

Any thoughts would be appreciated.

Thanks

I reposted this in correct section. New to the forum, can’t seem to delete 🤷🏻*♂️

Nothing wrong with the way you played it...I also would have folded. There were too many possible hands that had you beat...live to fight another day, and you will be successful in the long run.

I think that with the range that you put him on, a fold is the correct play. I would have only been able to call if I had some read on him that lead me to a call. I don't think that this is to nitty.
