You need to bet way bigger OTT. Donking flop is also fine.

As played he's gonna have JTs, 99 here almost always. I don't think he would raise 2pair here with this size, so I think its a good fold.

I would bet bigger OTT. The fold is fine vs this sizing imo.

Leading flop multi-way with weak players in pot..... Your stats are kind of meaning less after 26 hands.... And like the others said bigger is better on turn :) nice fold on river

Overbet is even better i think than this small size bet on the turn. So bet bigger like min 60% of the pot, but close to pot usual. He does represent JTs, 99 as a value range like 7 combo so not that much combo. His push is a ~pot size raise so he need to have ~33% of bluffs in his range, to make U indifferent like ~3,5 combo ~4 combo. Your really small turn bet makes that fold thougher and really exploitable I think, but it's okay versus the population because he's maybe never bluff in that spot.

Consider playing 33,55 by leading huge on flop.. try to build the pot when you are multiway OOP..
As played..On TURN street -- you have to charge Top pairs + draw's and charging should be expensive for them... close to 90% pot bet. and even over bet sometimes it's a good idea.
