Hand converter just doesn't work, i pasted them from my hud but no dice.

UTG -

HJ: 57$ (32/18 one of the better aggressive regs)

CO -
BTN -

SB -

BB (hero) 57+ Ts9s8d7h

utg limps, HJ makes it 2,25, folded to me, i make it 7,5 utg folds, hj calls

FLOP:4c2d7c i bet 10,5 he calls POT = 36,75

TURN: Ac i decided to bet/call 7$ but he ruined my plans by just calling

River 4o check/check he flips K654

Should i have made it larger on the turn???

2nd hand
headsup against very aggressive fish (very sure he is a fish)

Hero 200$ KQJ8

Villain: 200$

So he makes it 1.5 i make it 4.5 he calls

Flop: 769r i check he bets 4.5 i call

Turn: 4o I check he bets 18$ i make it 59.5$ he calls after stalling a bit

River 6 and i check fold

But what if river was a blank, we've got just under a pot sized bet and i remember making this play against a reg awhile ago where i just went all in on river and got snapped by the nuts. It's an easy call with the nuts against a c/r on turn on a rainbow board. I would be all for going all in if the board would've had a flushdraw out but i don't know about this. Should i still do it against fish for fold equity? Or is it likely enough he'll fold against a half pot bet that we shouldn't pot and running into the unlikely scenario that he slowplayed the turn?

I'm sure some of you will say this is a spewy play but i like to make it sometimes so...
