25NL - Top 2 pair on monotone flop line against decent player

[Prodigy54321]

decent may be an understatement..I haven't been paying excellent attention to him, but from what I have seen...he plays well...he is 25/19 over about 300 hands

couldn't figure out what the hell he could have here..

I hadn't seen him call down in a hand like this before..he was always raising or folding...raising big at that when he flopped a set or something

on the river, I was going to put out a bet and fold to a raise...then errr...I dunno, I checked to induce a bluff [img]/images/graemlins/tongue.gif[/img] but I was clueless here..I payed to see what he had [img]/images/graemlins/tongue.gif[/img]

any thoughts?
