Raise harder, pre and post flop. If 5BB gets 3 callers, try 6-7. Make them pay till they cry, bleed and are scared to be in a pot with you. If the loose player in your example raises before you reraise with AK, isolate and punish his weaker cards.

Loose tables have higher varience, it comes with the terratory. Stay tight and as long as they are drawing against you, if you keep hitting hard with made hands and you will make money, its an undeniable fact.

You cannot read the cards of super loose players but you can read there betting patterns, what they do when they hit their 2 pair or draw. Don't try to read their hand, just their overall strength. Rate your hand out of 100 and then rate how how you think they feel about theirs and see how you go. Remember, just because the 3rd flush card hits it dosen't mean they have it.

If confidence is a problem and your getting gunshy, try dropping down a level untill it comes back.

Or if all else fails try Counterplay, the whole thing might be a bit too tight for 6-max but there are some quality ideas to beat these types of games.
