folded to QQ in early/middle position, raise 4xBB. Button, BB both call. Flop AQQ, BB checks, Hero???
My thoughts: If I didn't have a queen but did have Ax or high pair then i'd be raising 2/3 pot to test the waters. So should I be doing the same with quads? I think that check-raising will cause an insta-fold from most hands other than AK and AA, and check-calling looks mighty suspicious - and then what would I do on the turn?
