Cold call pre-flop.
Check back flop without more information.
Bet turn and it sounds like you can do it for 3 big reasons: you want to get value from AK type hands, you want to induce K9s type hands that didn't continue on the flop to check-fold, and to go to war if you're check-raised.
Like others have said, your bet size to accomplish all this on the turn doesn't have to be large.
An interesting idea is that now that you've checked back the flop and plan to bet this turn with hands this weak that you may want to tweak what used to be your flop betting range
