To compensate for a bad river call, a bad turn fold?

[Entity]

Villain is TAGlike but is wayyyyyyyyy too tight (17%VPIP, 7%PFR). Has not seen a showdown yet.

i like, i think he missed a limp re-raise with a big pair or flopped a set (somewhat less likely), what else does a 17 vpip limp utg with?

i think 55 may be the only hand that you still beat.. which still has loads of outs.

i had a similar hand where a tight player limped UTG. he held 88 and flopped a set.

Quite a fold, but I think its ok. You're probably going to have to call a river bet also, and I don't think you're good 1/4 of the time against this villain.

On the other hand, you might have 5 live outs...
