Reads:
Villain was unknown. I've been new to the table and had only seen one hand, where he limped KTo late, called two bets with absolutely zilch on a lowcard board, to scoop a ten on the river and win. So that looked donkish, but this was a small pot. I don't have any stats or more of a read.

Pre:
I try to collect the dead money and hope to take the pot down right away. My thinking is that a raise from the SB looks pretty strong here when only UTG can have a real hand. I am prepared to let it go if UTG pushes or be very careful if he calls.

Flop:
With Villain in CO calling I put him on some PP most of the time, maybe some suited stuff. So do I c-bet? My thinking was that even if he likes to call a lot (as indicated in the one hand I saw), he will have a harder time when the pot gets bigger. I am still repping a monster, so he should fold anything but a set.

Probably this is all standard and I just fold now and go on. But I am curious if I did something stupid.

imo this is a small PP most of the time. I think I C-bet, but there is no need to C-bet this high. make it about 90 or 95, fold to the raise obv.

cbet $99.95 to flabbergast him. then shove turn.

You have 202$ to call in a 629$ pot, so you need only 32.11% of equity (not sure of my maths).
Against a range of 22-JJ, AQs, AJs, JTs, QJs, 54s, AQo, AJo (very wide), you have only 31.901% of equity...

So, pot/call or check/raise all-in or check/fold or bet less/fold.

i think this is pretty standard,
villain most likely just caught lucky on the flop and your play is going to take the pot down +67% of the time so it will immediately show a profit. Dont worry about this time him catching good, if he made a play, power to him, you still only have about 24% to improve over his pair hands that haven't made sets yet. Dont sweat it and just move on to the next hand.

bet like 80 or shove or just c/f or crai, just dont do what you did

agree with everyone else... smaller c-bet imo.

seems like he should have a pair so betting less is just gonna make it less likely that he actually folds it

bp/call, shove, or check behind, betting small makes him call or do what he did....

I would lean on betting exactly pot or shoving
