Lead the flop. This line is so obvious.

Your check-raise doesn't "look like a bluff," neither does your river push. If I were playing against you I would assume you were a fish trying to be "tricky" and put you on something like what you had.

You have to realize that in poker, your opponents expect you to try to decieve them, and have in their minds a certain way in which you'll go about it. It's your job to do the opposite, which in this case, is leading out on the flop (which has a number of benefits aside from concealing your hand).
