$100 stacks, 100nl 6 handed. new table, no reads. edit - assume villain is a floating type (could call flop with 22+, gut shot, etc.)

what do you think of the turn play, and what if the turn was instead?

I have :As: :Ks:

I raise UTG+1, BTN calls.

Flop $8.5, heads up

I check, he quickly checks

Turn $8.5

I bet $6, he pauses and raises to $18, I quickly raise to $40...
