Preflop and flop look good. On the turn I would be betting larger for value. You have a very strong hand so put some money in. This is a hand I also want to go bet bet bet with and going small on the turn doesn't allow you to get all the money in without overbetting.

The river lead is gross. Any info on villain would be great. Him taking a x/c x/c line with a flush draw seems a little unbelievable unless he's the really passive type. But if he's passive he probably doesn't have a lot of low suited hands pre and maybe not even a lot of suited broadways. Luckily he should have very few flushes combo wise either way.

I think AQ might be too strong to fold here so I'd click the call button.

I much prefer a bigger bet size on the flop. OOP a lot of micro stakes villains will check call any weak kicker Ax on the flop and the turn then folding the river a lot of the time. Betting bigger on the flop and turn ensures you maximise value from this part of the range, while the number of hands he will check call the river remains small.

As played I'm folding the river. It's probably exploitable but I can see a 2NL player slowplaying a set this way as well as having JT and a flush. Is he really playing A9 this way?
