River raise, can\'t fold to 3bet.
 

Villain has been frequently checkraising the turn against me and others, but has been showing down winners for the most part. He also loves to slowplay. Checked every street in late position with 77 on 557 board until the river.

How's the river raise given that I will never fold to a 3bet from him?

Looks fine to me, he quite possibly had two smaller spades. I think your 2nd-nut flush is worth a value raise.

i like it as well. If he has the K[img]/images/graemlins/spade.gif[/img] so be it. This is less likely since he just called pf though.

Could capping ever be correct here?

It's good. You have to raise. Calling a 3-bet is closer but I think he'll loss his mind with some junk often enough.
