A7o steal in CO vs. LP CC'ing BTN

[neurotiq]

Button is really loose-passive (42/13/1.06).

My first hand at the table, I post in CO. I'm dealt A[img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/club.gif[/img]. All folds to me, so I raise. Button cold calls. Both blinds fold.

I c-bet, button calls. I'm not putting him on a queen, since he probably would be raising in this spot.

I c-bet again. He calls. Now I'm not putting him on the ten, either, as I think he would've raised there.

I check. He bets. I...?

I'm kind of tempted to call in this position. Although it's possible that he had a ragged queen that he didn't want to raise with earlier, I think that villain's range is big enough that it might be profitable to call (possibly to a chop) on two pair with top kicker. I'd be curious to hear what you think.
