The preflop raise is fine. One commented it leaves you with a bloated pot multiway. This is a situation that A10 hates but 66 loves. Your hand is EASY to play against 3 or 4 players; just check and fold unless you hit a set or weird over pair. Against 1 or two players you can bet the flop and take it down most of the time.

That being said, when you hit gold on the flop go ahead and bet it. Your opponents will put you on AK and pay you off.
