Ronki: what bad outcomes (specifically, not just 'it isn't done that way') would result from you training at the same club as someone you want to fight against again? - They may not agree to fight you later since they train at the same club? - They will know how you fight from seeing you train/sparring with you so will have an advantage? (You would have the same advantage over them though.) - Something else? And more to the point: is it worth not training at all, to avoid that outcome, given that you say that despite there being 10+ clubs in your area, all of them have at least one person you want to fight against again training there? Note that not training at all will also result in you not fighting any of those guys again. Even if training at a particular club would prevent you from fighting some of those people again, it would allow you to compete in general still. Even if for some reason you really cannot fight against anyone who trains at the same club at all (are there explicit rules against this?), surely not every single person you want to fight again trains at every one of the clubs? I.e., you could pick a club and train there, losing the ability to fight, say, 30% of those people in the future, but you'd still have the 70% of them who don't train at that club.
