Inverted kimura

"Jiu-jitsu is chess." This lesson is proof that the old cliché is correct. Renzo attacks Leo Tunico's left arm with a kimura -- check! To escape, Tunico opens the half-guard, repositions himself and uses his right arm to try to block. Renzo then announces checkmate: He abandons the left arm and, with an inverted kimura, attacks precisely the arm that Tunico was using to help the other. Check out this brilliant move.
