I played a number of sit & go tourneys this weekend and had pocket aces about 6 times. I played each a bit differently due to position and chip stack, but I lost on all of them to rivers. I generally push a good pre-flop raise to eliminate some fisherman; however, some folks will call anything with anything. Example, I was first position and raised 3xBB, everyone folded to the button and he re-raised me about 8xBB, I raised all-in he called. Cards were turned, I had AA he had J-5o - won on the river with 3 jacks...
