AF = 13!!! wow.

I cant see an agressive player checking the turn and river with a set or better, something like 98 or 87 would have probably raised somewhere as well.

Is put out a small value bet around $8.00 so that TT, JJ, T9, A9 etc. will look you up.
The only way id check behind is if your image is manic enough that he feels you wont check behind the river - allowing him to CR the river.

Since my river bet is 1/2 pot it might look like a bluff so Id probably call a CR.
