No particular reads on villain.

Effective stacks are $500

Preflop: Hero has 66 on BTN

MP raise to 15, villain (CO) call, Hero calls

Flop ($45): K6 3: MP check, villain bets $25, Hero raise to $90, vMP fold, villain calls

He never has KK and I think he almost always comes over the top with 33. I think his range here is almost always FDs or 45.

Turn ($180): K6 3 K
Villain bets $50 Hero raises to $100, Villain calls

I boat up. $50 bet screams FD looking to get good odds, so I think that's still mostly his range. I gotta think any Ks left in his range come out firing bigger here. 33 makes sense but like I said, I think he re-raises sets on flop.

My raise sizing here is obviously bad, I had some reasons for it at the time but looking back it seems unjustifiable.

River ($380): K63 K 3

Villain leads out for $90 Hero ????

Snap call? Am I ever good here? Is he ever bluffing?

Call. If he actually has a K here, he's giving you fantastic odds. You have to call.

If he bet half the pot, then you have a real decision.

if he's bluffing, what hands is he trying to get me off of?

river is whatever, your turn play is awful. Raise should be 150-200, minimum.

agreed 100%. i dont know what i was thinking.

No, you're probably almost never good on the river. But still call. Call because you screwed up on the turn so badly that you need to to feel the pain to remind you never to make such a horribly sized raise again.

(FWIW, I think Ac3c, 4c3c, 5c3c, 6c3c are all in villains range as blocking bets; maybe 63 too -- this fact alone makes it a call).

Honestly, I might just shove turn. At this point, you want to get paid from trips, not from flush draws. And most villains can't fold a K here. Shoving saves you from feeling disgusted when a 3, 9, T, J, Q, K, or A peels on river and villain shoves into you.

His atrocious sizing makes this not a sick spot, you have to call. It is a sick card tho... sizing this small def means there is a chance you're good IMO. he may have something stupid and just doesnt know how to procced with it, like tens or something.

This was my thought. Villians terribad bet sizing makes me think he is probably very fishy, and that plus the great odds your getting makes this an easy call.

Actually dont mind turn sizing, if villain is drawing dead, no need to scare him away.

River is a sigh-snap call. Dont think too much. Imo he bets bigger with K-X, but at the same time his donk on turn after being c/r'ed is worrying/indicative of him having some KQ/AK's. Still call tho
