I was trying to think about this from a puzzle/optimization problem P.O.V. and not propose a topic that can devolve into a pissing contest or style vs style debate but I was wondering what people thought are the MOST VERSATILE submissions in grappling. Versatile meaning they can be applied from lots of positions, so like guard, sidemount, mount, backmount, standing, etc etc etc, without losing points on efficacy and success rate. So if you can hit a heelhook from literally anywhere with 1% success, I wouldn't consider that versatile for the purposes of this discussion. My top 2 are: Straight Armbar - can be done reasonably easily from...mount, side mount, knee on belly, bottom full guard, back mount top, and also standing as a flying armbar (not very high percentage, imo, but I think it could be amongst good fliers so I won't exclude it, I don't do flying stuff so idk). Kimura - can be done reasonably easily from...side mount top, 1/2 guard top, 1/2 guard bottom, full guard bottom, standing as counter to rear body lock, north-south, knee on belly so that's ~6 vs ~7, and that's just off the top of my head, what I've seen, what I can do. Anyone else have ideas to add?
