In general, I don't like it. Can't be sure which of our outs are clean, and it's still early in the tourney - no reason to take a big risk at this point. He tried to push you off your c-bet with TPTK (which he called a raise with ATo and way overvalues TPTK hands - definitely worth noting)...let him have this one.

But, if you're going to go the route you chose - might as well push the flop.
