Calling flop raise was horrendous, especially from a tight passive player.

You were probably shown a bluff after you folded, and it prompted you to post this HH, but know that the real question that would benefit you isn't whether to call river.

Fold to flop raise. As played fold river.

Not sure about your read, I know what passive and spastic mean but they're kind of opposites so I'll ignore them. What could a tight player have here that you beat on this river? All I can think of is 98s that flopped a GS + two overs + bdfd, but a tight player would often fold that UTG + 1 pre-flop when facing a raise. His line looks a lot like a pocket pair 77-JJ that flopped an overpair, got scared of the K on the turn, and then bet for value when you checked turn and river. Don't know what to make of the overbet, but we lose to a lot of his bluffs here as well.

yeah tight-passive and spasstic are kind of counter intuitive.

Not crazy about opening ATs UTG.

Hate flop call, if we were IP here I don't mind floating with BDSD+BDFD and 2 overs if he have a good read sometimes. but a reverse float with this is just bad, your almsot always checknig the turn and hoping to get a free card on the river.

Now the river comes:

Can we get him to fold better then A-hi? well probably not, he probably doesnt bet this river thinly.

Will he be bluffing here and can we hero call him? there MAY be some bluffs in his range if hes spastic, its not uncommon guys will bluff raise flop IP light but at the same time if hes overpotting river I need you to give me a reange where there are 33% hands better then A-hi here.

I feel like this is alot of FPS going on in this hand

His line is weird, but there are not a lot of bluffs for him to have other than pure air. This is probably value-spaz.

called flop raise with Ace high, and BD FD/SD only vs tight-passive player that called your PF raise from EP?

His raise screams an over pair to the 6 if not a set, probably an over pair because a set bets that K.

Why didn't you turn your hand into a bluff on the turn or river if not both?

AP, it's a fold and move on spot.

focus on college, not poker

What is happening here?

Fold the flop.
Fold the river.

Calling the flop is just so bad.
If for some reason you really think that he is FOS on the flop then 3bet, don't just flat.
But really, just fold.

You evaluated him as passive player so fold flop. The whole point of cbetting light against a passive is the fold equity.

As played I feel the villain played really weird and a bluff catch might be warranted (78 is the most of that range), however not to the 120 size. I feel villain shows a lot of ak, kk or aa here, as he would not usually 3bet cold pre immediately. The action is consistent with those three hands.

This is one of those situations where the river decision doesn't even matter, because you should literally never be here.
