you can cut the thing in two, so how he decided to plan A then if the plan don't go well, you can display his have hidden plan B. Cannot work on every single action taken but can be interesting. Also, if you want to hide his plan you must let some info in the chapter. For example, if you want him to do, have hidden cart, they must be told somewhere, like if he got a tailed beast in captivity before making him reveal it on the battlefield. Hiding completely something is not good since it will look like plot armor (can work one time, but not many or it will lose its impact).
