Edit: Fixed topic title

So this is like the 4th or 5th time me and this dude are getting into a blind battle this session. So far I've CRAI'ed the turn on him with an overpair and he called with a combo draw, and in another hand I checked the rivered nuts to him hoping he would bet but he checked behind instead with TPGK (doh). He's a good player post flop. I tried to be a little tricky here but I think it backfired on me and now I'm in a tough river spot. Call this or not?

Neither of you are blinds... False advertising....

And, I prolly fold the river..

1) There should be a raise somewhere in this line. Turn is best IMO.

2) I call.
