nut flush on paired board vs. superrock

[sluttysteve]

villain is 18/0/0.33 over 30 hands, small sample, i know. turn line is questionable, but given how the hand played, is this an instacall on river or can i consider folding?

bad turn check cause pot's 3-way so villains thinking it's more likely someone has a flush and checks it thru. then when you lead the river and get raised you can make an easier tough decision. plus your bet on the river is pretty weak so maybe he's trying to bump you off summin tho it looks like he boated up.

You really think CO is limping with AA/88/77? Not me. His stats are definitely weird, though, but over 30 hands they don't mean much.

Btw, pot the turn. River is whatever. You need to bet the whole 25, and then the raise calls itself. As it stands... call.
