QQ post flop ?

[snapfc01]

u raise 5x bb with QQ and get a call... do u always bet out? if so pot? b/c that is usually 1/3 of your chips and the pot will be too big to get away from... do u do a 1/2 pot bet if an over card hits? i don't think you can check if any a or k falls... seems too weak for me. just wondering people's thought on playing it...
