I was playing .01/.02 NL on pokerstars last night and at a table for about 30 minutes was catching a good string of cards (with the exception of a loss with cowboys against AA) but I don't mind a loss like that. However had a string of tough beats at a table earlier and at the new table, I guess I had that image of I only raise with good hands because alot of people folded when I raised? Anyway a new guy sits at the table for about 5-10 mins and is playing pretty loose from the begining. He got called on a few bluffs, so I'm in the small blind I get thrown I raise to .08 bb folds and the new guy calls UTG.

Flop comes I bet .12 and get called
Turn bet .12 get called
River bet .12 get raised .20

Now I was fairly confident he was chasing a flush but was playing so loose since he sat down figured he might be bluffing again. I call he has . I know it's fairly common at ML tables but is there anyway to get people away from chasing a flush?

Also just wondering how alot of you guys play a big ace when you're in the blinds say A,J or better?
