I'll go out on a limb here and say I think you played it fine postflop. As everyone else says cap pf duh.

Postflop though, that checkraise is almost never a set and is usually something like KK or another very strong one pair hand like AJ. Given that and that you raised the deuce on the turn that made a flush draw (and look very suspicious) I think the cap is fine. When you cap a street it gets you a very honest reaction on the next street. If he bets you should probably just call, had he checked you would bet of course.
