Checkraise river for value?

[MTBlue]

Standard 2+2 tag three bets light etc etc. Never really played a big pot against him. Not interested in the flop or turn comments. Sometimes I bet sometimes I call sometimes I checkraise. Turn I think I've got 11 outs here alot.

Betting the river isn't an option b/c the villain has never seen me bluff a river like that. The river bet size froze me up. I haven't played enough with villain to know if he is capable of slim value bet in this spot.
