"In effect, Chi Sau gives us the ability to "see" things about the opponent's attack that our eyes cannot see, to 'read his/her intentions' at a neural level, thus accelerating our potential to respond effectively. Practising 'Chi Sau' with 'soft force', or with pre-arranged sequences, unrealistic counterattacks from impossible situations, and the implementation of 'rules of engagement' (such as no attacking to the head, etc.). totally contradict the purpose of the exercise. This is not to say that we have to try to bash our training partner at every opportunity, but that we need to make the drill as close to reality as possible. In combat, if we clash with an opponent, force will be applied, especially the enemy (after all, he/she is trying o hit you!) Therefore, in Chi Sau practice, we need to apply forward force, with an intention to attack if and when an opening occurs or an attack succeeds. The energy used should be flexible, like compressed rubber, not stiff-like solid steel, with firmness and not tension. This approach should begin with the 'single-hand' exercise (Dan Chi Sau) and continue on through to the Gwoh Sau or 'free-attack' stage. Only in this way, free of restrictions and with an emphasis on attacking the man rather than 'chasing the arms', will the Chi Sau drill bear any relevance to real combat."
