Top Pair vs 3Bet on villain 38 VPIP

Good fold. Unless you have stats/reads that show the villain is hyper aggressive post-flop, this is a standard fold. Often high VPIP players are passive, and only play aggressively when they have a good hand, so that alone doesn't give much information.

Looks good. Maybe a check behind on the turn for pot control could also be valid option.

4-5bb isolation preflop, u are missing quite a lot by not isolation with higher sizings. U are also giving others great spot with lower sizing to jump into spot with marginal hands due to implied odds from fish.
On flop again bigger sizing. Same on turn. Fold seems ok without reads/more info about opponents.

With strong hands /top pair good kicker absolutely is vs fish/ i would suggest bet/bet/bet big sizings at least 3/4 of pot.

I raise 4bb preflop, as played Imho :nh:, turn is a nice bet fold for Baluga:banana:

Pre ok.
Flop size is too big for sure and exploitable.
Turn is a trivial fold, you have sets, AQ, AK and JT. I'd also check that turn with AJ, don't see any point in betting again where there are no draws basically.
