Going through some hands from the past that I've written down. Sorry as I did not note any reads. I've written a few assumptions that were likely.

Hero button 30,661: tight aggressive image

Villain1 hj 48,424: likely was opening and raising limpers a bunch from late position

Blinds 500/1,000 100 ante
8 handed

Preflop 650
utg limp
mp1 limp
V raise to 1,250
H 3b to 2650 A5
blinds & limpers fold
V call

Flop 6,550 A85
V check
H bet 3,000
V raise to 6,000
H call (decided to flat and let him continue with worse hands. or should I have raised?)

Turn 18,550 K
V bet 8,000
H ? (continue to just call, or get it in here?)

Your blind sizes are wrong, I assume its 150/300 with a 50 ante to make taht preflop pot size and the action make more sense. With those stack sizes 3b alot bigger, closer to a full 3x, around 2.75 imo. Again, with stack sizes bet 2/3 pot or slightly less (to induce) imo, just shy of half seems an awkward sizing. As played I'm inclined to flat flop raise, either jam turn or flat and call off or bet good rivers thin for value...if the flush comes in im really not sure and would be villain, bet size and timing dependent (which tbh also affects whether im jamming turn or flatting).

Rethinking it I'd rather bet flop slightly smaller and make a 2.5x 3b if he raises/ call 4b or 5b get it in or if he flats the small bet bet substantially larger on non-flush turns.

Sorry was looking at a different hand I wrote down.

Blinds 150/300 25 ante

If the villan is that active I can fine with the 3 bet but make it bigger
Just shove the flop over his C/R

yeah shove turn as played
