I think you need to bet the flop so that people with gutshots and backdoor flush draws dont get the odds to take one off. If you get raised on the flop, you will have given them the wrong price, or drive them out. You should only checkraise the flop if you can expect the button to 3 bet and clear the field for you. I think its right to checkraise with a draw there to build the pot...
