Last night's class started with the Back sweep. This is a good one to use if the opponent stands up out of your guard. As the opponent stand up, maintain a tight guard until he drags you underneath him. Hook the back of his ankles with your hands as you release your legs, dropping your shoulders to the ground as you bring your knees together. Your legs should now be resting on top of his thighs, near his hips. Now, pull on his ankles as you thrust your feet forward and then down. The opponent should go right over. For those that have seen my tournament video, this was the sweep that I did there, FWIW.
Ideally, you should release your grip as the opponent is falling, and follow him over, ending up in mount. I have a hard time with that still.
Next was the Front sweep. This is for when the opponent stands up, but leans over you trying to pin or stack. After getting a grip on his elbows, release your guard and put your feet on his hips, and start to stretch him out. Many times, the opponent's reaction will be to push in and re-establish the stack or pin. As he comes forward, pull him forward and down as you elevate his hips, getting his feet off the ground. Now (having already isolated his elbows to make it difficult for him to post out), roll back over one of your shoulders, ending in mount. The key is to roll tightly, not kicking the opponent off you. If there is any space during the roll, the opponent will be able to escape the mount.
Last was the cross-lapel choke from mount. Mount is actually not one of my favorite positions to work submissions from, as it is hard to stay balanced when doing them. The choke works by taking one hand across the opponent's body, to the opposite side lapel (ex: your left hand to opponent's left lapel). The hand grabs palm up. Your other hand goes on the same side, behind his head, grabbing his collar with your thunb in, palm down. Now quickly loop your elbow to the opposite side, going behind his head, ending with your arms crossed in front of his neck. Lean your head down, while pulling your arms to your chest to complete the choke.
My instructor gave us a good tip about using our knee to load one side of the opponent's chest when leaning over to set up the choke. It did make it more difficult to escape from underneath when the top guy did that. It also help with balance, since you can come up on the ball of the foot as you lay your knee against the opponent's chest. This allows you to post out on that foot, in case the opponent tries to sweep you to that side.
He also gave us a good tip about "curling" your arm (to drive your elbow in the opponent's chest), when doing lapel chokes. Very uncomfortable for the guy on the bottom. It does help raise the opponent's head, to facilitate going for the back of his gi.
Did OK with the active drills, focusing on standing guard passes this time.
Rolled with one of the other white belts, where I was "Johnny Foul" (unintentional, LOL) for the first match. Got an OK double leg takedown on him right away, but ended up in his guard. I immediately postured up, sitting back, and went to combat base (one knee up, between his legs). Except I ended up catching him in the sack as I brought my knee up. DOH!
After profuse apologies on my part, we resumed the match. I was later able to catch him in what I thought was a guillotine, while in his half-guard. Turns out it was more like a neck-crank, and he was a bit stiff and sore from that.
We also had some od the more experienced guys in class coaching us, which was pretty cool. I sometimes will get dominant positions, and then blank out, not knowing what to do next. So, it was helpful to have someone yelling "UNDERHOOK! PULL HIS HEAD DOWN!" Etc. We did a lot of reversals on each other, LOL. Fun stuff. Felt almost like being in a cagematch.
