Judo is an art of deception, you must learn to program your opponent on one thing, then surprise them with something else, it’s called “creating patterns”.
Attempt one type of technique, twice or thrice until your opponent starts to believe that they have you figured out, once they start anticipating the same technique, go for another one and you will surprise them.
It sounds simple, but the difficulty of deceiving and faking remains in having to create patterns in your opponent’s head, and at the same time, it remains in having to read what your opponent is doing, and also figuring out the patterns they are creating in your mind.
You have to be a multitasker judoka and do both things simultaneously, decyphering your opponent’s patterns and creating your own. That’s the difference between a high-level judoka and an average one.
