I would donk or c/r the flop. You should be trying to get stacks in. A good line in this spot is stack-a-donk: lead flop, c/r turn, shove river. When you're way ahead, worry more about getting the money in than what he might call with. If he folds, you probably weren't going to win alot anyway, but you can't waste legitimate chances to stack people, esp at 10NL where everybody's on semi-tilt anyway.
