I'm having trouble deciding what action to take when I have a strong hand on the flop and am raised. I'm not sure if this scenario addresses my questions perfectly, but maybe it will generate some discussion that will.

50NL full-ring, 100BB stacks, no reads. Two limpers and you raise to $3 in the CO. Button calls everyone else folds.

Flop - Qh 9h 3d (pot = $7.75)

You lead for $6, Button raises to $16. What's your play with...

1. 99
2. AhKh
3. AdAc
4. JhTh

Feel free to tweak the scenario of you think it will make for a more interesting discussion.
