I usually go about 2/3 pot.

I think checking the flop is really awful in these scenarios. If you absolutely must have some slowplay in your world, check the turn if it comes with no draws. This is good because obv. you aren't letting draws in for free, and every single donk in the world loves to pressure someone who cbets then checks. Then you can raise the sucker when he stabs at your 'weakness'. I think this line is way better than checking flop.
