Hi all. I'm playing in a hand and don't know if the player is floating me or not. I was multi-tabling and the guy had just sat down.

Scenerio:

Hand: AhQh
Position: CO
Game: NL50

Everyone folded to me and I raised to $1.75. The BB called. The pot now has $3.75.

Flop comes Jh 8c 2h.

He checks and I bet $2.75. He thinks a second and calls. The pot now has $9.25.

The turn comes the 8s.

Now, I only have Ace high really but I do (if he doesn't have a set or just made trips) have 15 out or I have 9. I'm wondering if the best play here is to bet the turn as well or to check and take a free card and evaluate the hand on the river?
