Here are a few of the many Fighting Principles used in Sendo-Ryu Karatedo:

1) Finish your attack when your opponent starts his attack.

2) Use high positions, which are easily changeable and help you
     to counterattack in a shorter time.

3) Try avoiding your opponents attack rather than blocking
     them, leading the opponent to make senseless attacks.

4) Don't stop attacking unless your opponent is down.
