I'd say you don't have draw. Because, if you have one, you'd check the flop, get the button to bet and try to get the fish in the pot. By leading out you might get the pot headsup with the fish.

I think a made hand, and you are afraid of possible draws so you bet out on the flop. On the river you don't slow down, so I think you can beat two pair. You would probably muck A8 and A4 preflop against a tight TAG OOP. That leaves 88 and 44.

As a sidenote, I also like this line as a total bluff vs. a scared TAG. However, a fish is in the pot and this would be a very bad spot to bluff.

So my guess: 44.
