[NL100] I can't fold this set can I ?

[Frelled]

On the river, I know there's a 4 straight but there's no way I can give him credit for that is there ?

I figured his range for the push could include 2 pair, an under set and maybe even busted flush draws and I felt compelled to call.

Villain is loose passive. 45/5/0.4

This is a no-brainer. Easy call.

[Acein8ter]

Don't tell us he had pocket 4's...

[early325]

No.

[tannenj]

how many hands are those stats over?

i'd probably fold this if your sample is reasonable.

Stats are over about 1000 hands.

Thing is, he's soooo passive it seemed highly likely he had a 4. I just couldn't see how.

Afterwards I figured a hand like 4h6h would've been possible but it turned out even that was giving him too much credit.

Obviously I lost but was I suprised when he turned over 4c7c.

My real question is, given he's so passive, is a fold reasonable or are there enough hands that I'm beating, that would play like this, that make the call +EV ?
