Osvaldo Augusto Queixinho teaches a new technique in this Gameness Free Instructional Video that can be used whenever your opponent attempts to sweep you from guard. Osvaldo is wearing his competition Gameness AIR blue gi in this video, and his training partner is wearing his white Gameness Pearl 2013 gi.
When in your opponent’s guard, they will attempt a sweep where they grab your collar and sleeve, and use their legs to roll you onto your back. This technique is a counterattack from this sweep, and begins as your back hits the mats. Once you hit the mat after your opponent finishes the sweep, keep your arms straight to ensure that your opponent does not manage to make it into a mount position and get on top of you. This will result in you losing the opportunity to complete this counterattack technique.
From this position, bring your knee up the middle until it is between the legs of your opponent. With your outside arm, control your opponent’s other leg with an over-hook. This will prevent your opponent from both closing the space between you, and from freeing his/her leg from the hold.
Slide your grip down from the calf of your opponent, down to his/her ankle. With your outside foot, move it up until it is pressing against your opponent’s hip, and over their leg. As you can probably tell from here, the counterattack is going to be a straight ankle lock. Push your opponent away with the leg in his/her hip until they fall backwards. Ensure that you maintain your grip on the ankle. To complete the submission, make sure your opponent cannot come back up on top of you, roll to the outside, and straighten your back.
This submission will put pressure on your opponent’s ankle and force him/her to tap out.
