AA played passively vs. fish

[zook]

Villain is a major fish. 52/0 over ~100 hands, will bet when checked to, likes to try to steal pots, will showdown marginal hands but I haven't seen him play for stacks. I put him on Kx here, but possibly air. AK and I'm getting his stack, weaker K's I'm not sure. How do you like my passive line and what's your play? Plan for the river?

c/r's all in

Flat call. If he has a King he only has 2 outs. I'll go for a check-raise on river.

c/r allin turn. passive player seems to of come to life on a dry board so i think he thinks hes goot here,if you think he'll fold to your c/r (fold TP)then call turn-shove river is good.
