However the rules still work remarkably well applied by only one partner. Fighting fair with uninformed or unwilling partner is more work and less satisfying but you will still get results. Also,your partner will pick up fair fighting skills from your example, just as untrained singers and dancers benefit from performing with more experienced artists. Even if your partner resists the concept of fair fighting, you will still have the same advantage over your partner that the Tai Chi master has over the street brawler. So study the rules thoroughly, and follow them with care.
