Top pair weak kicker and a suited board - Now what?

[Hotrod0823]

Last night after the 2 table SnG with the 2+2 posters I played a 10+1 10 dollar SnG and had an interesting hand that came up and busted me out.

First off the table was loose and I really had to hold back to avoid playing too loose and tried to stick to my "normal" game without my normal "steal" raises from Middle or Late position. I was playing tight and hoping to see the table numbers dwindle.

Well Dwindle they did at the 50/100 level we were down to 5 players and I found myself in 3rd with about 2000 in chips. I had only played a few hands upto this point and was quietly gathering chips.

Now the hand in question:

On the button with A[img]/images/graemlins/spade.gif[/img]2[img]/images/graemlins/spade.gif[/img] (2000 in chips) Blinds 50/100: I raise to 500 and only the SB calls.

Flop: A[img]/images/graemlins/club.gif[/img] 10[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/club.gif[/img]

SB checks to me. [img]/images/graemlins/confused.gif[/img] What did she have? She was calling a lot of hands but not being aggressive. I didn't fear a check raise all-in (she had me covered by about 300). I decided with 1100 in the pot I was going to bet. I didn't want to give a free shot if she was on a draw. A pot sized bet was 1100 so if I was going to bet the pot may as well push all 1500 in. If she has the flush so be it. My intention is to get a fold right here. She folded to one of my big bets on the flop earlier.

No such luck! She called with Q10x and takes me out when my pair of Aces doesn't improve.

1) Was my PF raise a mistake or a standard play in this situation or is it a mistake to try and steal against a loose caller with A2s?

2) Was my play for the pot a mistake post flop? If she had a flush would she bet it? Or check it hope for a blush from me? But if she was on a draw I have to bet my top pair-correct? Is the best play to check it and fold if she bets on the turn? Is a 1/2 pot bet more reasonable? It leaves me with chips and I can fold to a reraise.

3) How good was her call? (other than the fact she was ahead) With bottom 2 pair and this board she was calling 1500 into a 2600 pot.

Thanks
