The mantra "position before submission" is a great rule of thumb when you first get started doing jiu jitsu, but after a few years, some of the rules in question can be bent or even broken. Side control is an especially dominant position, and giving it up to go after a leglock might seem like a silly thing to do, but under the right circumstances, leglocks from the top of side control can be a very effective attack. Further, they can often catch a very savvy opponent off guard. Here are some simple and not-so-simple attacks you can use from the top of side control. As always, make sure you understand the rules of your gym before trying to go for these while rolling. With proper caution, these can definitely be integrated into your game.
