How do you know?

Hi All,,

First I wish to thank Railbirds.com, and all involed for everything they do, my game has improved leaps and bounds from what I've learned here.

One problem I have is pocket pairs! I never seem to read this correctly and get my two pair taken down all the time by pp's

Early in a tourny, table's has been loose as hell .., I call with AQ suited from mid poss. with 1 in before me, CU min rasies ..all fold, i call .. AQ2 flop. 2's following suit I check, thinking I'm gonna reel one in, CU min bets, I raise, get called, turn 5, now I have 4 hearts, small bet .. I call ... forgot the river but it wasn't a heart.

now I'm into the pot heavy .. he pushes, I'm thinking #$&*@$, and maybe this is where I messed up, I call all in, didn't have much left.

You might have guessed by now .. pp2's

where did I go wrong????
