Preflop
I can be on board with both 3-betting and flatting, but if I 3-bet, I want to make it larger like 20c rather than just 17c. His VPIP/PFR are very high, and this does make me want to 3-bet more, since KJs is then almost a 3-bet for value. 15 hands is a very small sample though, so be carefull to not overadjust in general.
Flop
Great flop for you obviously, and this is an extreme way ahead way behind situation. He either have AK, KQ, K6 or 66, and then you are way behind and drawing to only a few outs. Or he is way behind, and most of his hands are pretty weak. Like 77-QQ, AQ, AJ etc. You are not going to win stacks against that kind of hand, and you want them to stay in the pot, so you definitely dont want to blast it.
You could actually go for a trap here and check behind hoping to induce a turn bluff or get some light calls from him later. But a small C-bet is also fine. However if you bet, you need to bet an amount, that actually matter. 4c into 37c is just silly. If you keep it below half pot, I think, you will get plenty enough calls at 2NL. So maybe bet 15c but not just 4c.
Turn
The Q on the turn is actually not a great card for you, since it puts pressure on 77-JJ, which should be a somewhat significant part of his range. There are some gutshots, that developed though, and AQ now has a strong second pair. So I definitely think, you still need to bet for value, but once again I would keep it on the smaller side.
Once again you take the small bet sizing to far though betting only 10c into a pot of 45c. I would bet something like 20c in this spot. When he check-raise you, its difficult to say, what it really mean, because your sizing looks so weak. So I think, he can have a decent amount of bluffs here, or he could be raising AQ for value thinking, he has the best hand. For that reason I would just call and give him the chance to fire another barrel on the river.
Instead you move all in, which is a massive overbet of almost 2 times the pot. This is the main mistake in the hand. When you make a move like this, you need to ask yourself, which hands he can call with, that are worse than yours? And the answer is pretty much none. If he has the AQ and is raising for value, then this action is certainly going to make him reevaluate, how strong he think, his hand is. And of course he is going to snap fold all his bluffs.
Results
This is a bit of a cooler, and even if you had sized your bets better, its not unreasonable to get stacked, when you have trips in a 3-bet pot. However you played in a way, where you would only win a small pot, if he had a hand worse than yours, and this is, what is going to kill your winrate in the long run.
