Well basically here is the scenario. New Tkd master arrives in town and challenges the only other tkd school master because he thinks he can do a better job. Scheduled full contact match with basic rules. Everyone has time to prepare. The winning master invites any willing student to come learn with the best.
So, is this a hypothetical scenario or did it actually happen?
Whatever. There are unanswered questions here. Since I get the feeling that this is a hypothetical, here are some considerations that make such scenarios rather silly:
What are the ages?
If master A is old enough to be competing in seniors and master B is still young enough to be competing in the same age range as guys from eighteen to twenty, master B has an advantage in a tournament scenario. They put those age divisions in for a reason.
What are the genders?
If one is a gent and one is a lady, this generally provides the gent with a size, weight, and upper body strength advantage. Just as with ages, there are reasons why they have a mens and womens division in a tournament setting, though I feel that as long as weight, age, and relative skill are close, gender is less of a factor.
What are the weight classes of the masters in question?
This is the biggie. Are the close in weight or is master A built like Dolph Lundgren (6'5, 235 pounds, 5% bodyfat) and master B built like Yip Man (5'something, 102 pounds soaking wet)? This would be the most significant factor aside from age.
Do either masters have any serious injuries?
If master A has blown out his knees or has severe back problems from from, say a car accident, he or she may be a wonderful teacher but will no longer be competative as a tournament fighter.
