25NL - trips faces river raise from good player

[Prodigy54321]

CO is a solid multitabler..might be 2p2 and I think he was following around the same donk that I was for a while [img]/images/graemlins/tongue.gif[/img]...he is at 19/10/1.6

I am so confused by his line though..I couldn't figure out what he could take this line with..I wouldn't expect him to check a set on the flop let along the river..a flopped straight is possible, but again...I can't see him slowplaying like this...

then again, I can't see him raising this river with anything worse than I have...

thoughts?

Yeah, that's a pretty funny spot- I guess A6 is your worry, any other 6 and your good for a chop obv- just expecting to chop with 65.
