I find myself running into trouble, in situations like this a lot. First off should I raise A9s UTG in a six max game? I would definately raise AT, but A9s in borderline for me.

I bet the flop, but feel like I have to bet the turn to charge the potential flush draw (I know my bet is way too small, that was me not paying attention to the pot size), villian would definately call w/ a flushdraw on the flop here.

Then when we reach the river I am splitting w/ the Aces except for AK, AQ, AJ, and I feel like I need to call anyway given the stack sizes (villian has less than 1/2 pot) and I might get him to fold something that splits with me.

How should I play these situations?
