ak overcards vs light river bet

[daven]

villain is loose and fishy - range is about atc based on the three orbits I've watched him at the table so far.
Turn wasn't good for me so I checked behind.
River gotta call, right?

I was thinking against some opponents it's better to raise, against others it's better to call.

If he folds 22-99 to a river raise I would go ahead and make that raise.

Yeah I usually just call these cuz sometimes they're air but a ton of the time it's like, T7 or 5K.

yeah I'm just calling, i'd be much happier if the flush hadn't come not because I think he has the flush but I'd expect a lot more air in his range. I guess a raise is ok to rep the flush and I would def be raising if i had a small bet w/ weak hand or block/fold read.

if you had a pair this is a call a lot more than you think (eg even 77)
Also, this might be a call a lot too, there isnt necessarily a need to raise
