50NL: KK, villain c/c flop+turn then bet out on ace river

[flyingtriangle]

I had only been at this table a short while, no real reads on villain yet. I've seen him take down a few pots without showing his hand, and I've seen fold after putting money in when he encounters some resistance, so prior to this hand I'm inclined to believe he is a smart player and a bit on the tight side.

I'm pretty sure he hasn't been calling my bets this whole time with ace high. I was worried he might have something like AJ, but it seems like if he'd hit two pair, he'd bet less and hope for a call. I was also thinking he might have had 33 or 44 and slow played his set.

Is it +EV to call here? Would anyone be thinking about raising?

Gotta look at your bet sizing postflop.You are giving villain huge odds every street.I wont be thinking about raising the river-ever.The only hands that will call you down are the hands that you are beat.
33,44,JJ,AJ,QJ.It looks like villain is taking a pretty strong river line.
Ill most likely fold with given tight reads and pretty strong line.

river is definitely a fold. call/fold is big spew!

as it's a dry sidepot I don't mind the small bets on this uberdry board vs a reg/half decent player, but without any real reads I think just bet big anyway.

[ATOTHEC101]

your post flop bet sizing is terrible, bet almost double on both flop and turn, as played river is a fold.

I think all advice is pretty futile because I can't imagine that you can beat / built a roll for 50NL by playing this way.

You probably need to play much lower first.

I understand the problem with my bet sizing here and I agree that it was all wrong post flop. I think I was looking only at the size of the side pot when deciding how much to bet instead of the size of the pot as a whole, otherwise I would have probably bet about double what I did on the flop and turn.

your flop and turn bet-sizing suck balls.
river fold and never play kings this poorly again
