NL16 AA 3bet pot

You have a little sample of hands, but 69/0 seems a passive fish too me.
With that stats, I think he called you with an overpair or a flush draw, but it smells to me as a draw.

On the river, i would play check/call if the betsize was not too big.

He has 5$ remaning in a pot of 12$.

I would push the river to potentially get called by any pair. If you check then x/f as he is a passive fish and he will only push with flushes here.

In case he had it this time move along Sometimes the fish wins as well.

Btw I dont know whether or not this is your standard 3bet size, but consider 3bet oop a little bit bigger 9-10bb versus a 2x open, otherwise you opponent will get great odds to play IP with a marginal hand.

In this hand with a bigger flop cbet you can easily push the turn and get called by any pp. (maybe even FDs if he has no fold button)

Hi guys

Thank you for the analysis.
I made river push and he had 99..

Yep, that is my std 3bet size vs 2bb open but from now I will increase it to 9bb
