Did my first gi bjj tournament today. I won my first and third fights with americanas from side control. My second fight I lost on points, 2-0, fucking takedowns. Throughout the second match I was holding my opponent in the lockdown (by eddie bravo). In the process he tweaked his knee and had to pull out. Is this a legit 1st place or is it tainted? If it were an intentional knee tweak I would feel shitty about it, but an incidental injury from rolling? I just don't know.
