counterfeited 22 vs LAG, is a river bet worth it?

[Lurker4]

Villain here is a LAG, something like 67/33/1. I was planning on c/r'ing the flop. Is a river bluff worth it here vs a LAG? On the one hand, his range includes some hands w/out a A or K, but on the other hand, he might not need A or K high to call here.

Prima 5/10 (6 max)
