Techniques are sold but in reality they are only virtual training drills which portray and attempt to portray a sort of perception of principles to combat solutions.
So you have a training partner in the form of equal novice, advanced practitioner or even a respectful instructor. You have techniques to train with and a face to lose! The intricate interaction between the training partners is the key to success. The ability to communicate and understand the key components of the training drills and their limitations is of the essence.
One - Attacker is in the kicking range and you are executing the toreador defense. You timely evade any possible kick by moving to unexpected angular side position evading any possible attack and start with a chain of side kick followed by back hand strike finishing with elbows and knees.
Alternate scenario - Attacker is kicking a front kick to where you would move as he watched you before demonstrating your defensive move. Well this is why Jujitsu masters are in a habit not to use the same direction technique in each demo fearing from students wit.
Two - Attacker is executing front kick and you are executing inside defense vs. kicks... Attacker know you will advance in your defense because you have demonstrated it beforehand, and is lunging short to meet you as you move in, kicking you after the defense.
Three - You are executing outside defense vs. front kick starting with your arms in crossed position You move diagonally to cover the dead spot of your hip where your crossed arms do not reach, blocking with your rear hand while your front hand moves close to your attacker for the counterattack.
Four: Your attacker is doing a side kick and you are doing outside defense. However, your attacker is crossing in the front which makes it difficult for you to slide your fist behind his knee for a block. Well if he kicks like that he can only generate blocking force which will materialize only if met with your kicking force. Therefore you need to just keep moving forward for counter attack in any way possible.
Five: Attacker is projecting a front kick but is lunging and switching it to a roundhouse. If you did not manage to deflect his ankle horizontally, your inward move and your back hand crossed over your shoulder will provide sufficient defense.
You can always block all kicks with block kicks. However you need to master blocking with your arms as well. These techniques or more precisely drills will instill the efficient approach to any solution.
Many students got hurt by their instructor with no explanation. That lead them to fear of attacking with correct distance and force. The same underlying culture is inherent among training partners as well. It is important that instructors not hurt their students. At times, instructors are afraid to lose face, and must counter attack to show that the technique work. A better way is to explain that to the student before hand, and if needed prove it to them while wearing boxing gloves, or letting students wear shin pads. The idea is to prevent a culture of mythical training that is far of reality!
