$25NL noob - line check pls

Not much of a read - villain is 15/7/2 over about 200 hands, and he probably has me as 14/10/3 or thereabouts over same sample size. $1 was villain's standard opening raise. How's my line, and is my turn call here standard or spew?

I suppose he could have been slow playing Kings, but just as likely he has the nut flush draw and is trying to scare you out. I think he's got one of the two but I'll pay him if he's got me set over set. If he raised 4 BB with a 4-6 or 6-8 I reload and take what's mine back plus add him to my buddy list.

"15/7/2 over about 200 hands" qualifies as more than "not much of a read"

That said, this is a standard call anyway. Two taggs, no bets on the flop, he's not putting you on all that much strength even with the turn raise. He could still have QQ, JJ, TT, AdQd or just think you're completely full of it since you didn't bet the flop.
