Strange hand after flopping straight

[xcrack999]

Villain is 34/8/2.5 after about 80 hands. A typical semi-LAG, and my note on him says, "slowplays too much." Is it an easy call on the river? I just didn't see what he could have that I was beating. Thanks for the help.

I call here. Would he slowplay hands like w/J9, J10, 910? You say he slowplays too much but does that mean that he has been waiting until the river to pop a raise when he has position or has he been calling flops, raising turns w/strong hands. He could have Q8 which has to be your only real worry as you would expect a raise from KQ preflop. I would also assume he would raise TT, 99, and JJ preflop here as well. I call here and hope to see two pair but you have to just roll with the punches if you are shown Q8.

I would call and expect to see 2 pair or a set.
