Yep, pretty much the "Dirty Dozen" drill, based on how in the movie they had to talk through their attack plan. Then the Major alters one condition and they have to respond. Which is better, to memorize the plan or to be simply familiar with it and ready to adapt to change?

I liken the mindset difference to regular chess and speed chess. In regular chess, the opponents can study the board and determine every series of moves to their outcomes, then decide which move will lead to a set of most favorable outcome possibilities. This is the way computers are programmed for the game. In speed chess, you can't think through all the different move sequences like that, so you have to develop pattern recognition and strategic tendencies and use those "tells" in your favor. Being an advocate of Chaos Theory, I have little faith in pure chance. The reason is there are always subtle influences that tip the odds one way or another. It is almost intuitive how our minds can perceive and process these little influences if we learn to trust our instincts.

In any case, I think you've just got to practice by incorporating that intuitive process into your life more. Become a keen observer for one, then try and see what is coming, even in mundane situations. Pretty soon you will be thinking like that all the time, and then when critical moments pop up you can be a bit more prepared to think your way through the process.
