Limit Raises

I'm new to No Limit, but the biggest problem I'm having is getting raised small with a decent but not great hand. Th structure is the .25/.50 PP game. For example I hold Qh9h in the BB bet the pot ($3) on a Qs 8s, 2c flop and get raised ($3). Or, raising pre-flop with As, Ac getting 2 callers. Bet $9 at a Qc Jc 2h at $9 and getting check-raised to $18. If there were no draw, its a pretty easy fold. But my limited experience seems to indicate its 50-50 between a draw and a hand I can't beat. Advice wanted.

you need to judge your opponents and decide what they may have. also you need to mix up your play so they dont take shots at you. some of those times you look them up and some play back at them. if you dont you are a piece of cake to beat.

but if its really 50 50 then you should probably fold, especially out of position. but if you are wrong on your 50 50 guess you may not be able to beat the game.
