Recently, a couple of friends and I got to arguing over how well BJJ would work in a sword fight. Now, I know that avoiding confrontation with an armed opponent is always the best idea, regardless of how much grappling training I have. I'm under no delusions: I want to avoid confrontation whenever possible. However, my friends own a few practice foam swords, and are interested in a challenge match where I go unarmed and one of them gets a foam longsword. Other than a couple SCA events, they are mostly untrained, so it's not like I'll be up against a master swordsman or anything like that. My question is this: what tips and techniques should I keep in mind to make my BJJ as useful as possible in this scenario? Is there any chance of me coming out on top, or is the sword just too much of an obstacle to overcome? If I can close the distance and force things to the ground, it'll be over pretty quickly. Between me and that goal is a long pointy metal (or in this case foam) thing, though. Any advice?
