100nl | AKs - Shall I go for turn c/r here?

[Ratamahatta]

Villains stats are something like 35/25/1.5 but he have been playing very tight. I stole his blinds very often and he didn't play back at me.

I wanted to crai on the flop but he checked behind. Can I crai turn now? I think turn bet will look like a bluff after flop check and crai looks much stronger.
