What is S Mount?

[xnfx]

Can anyone tell me what the S Mount is, what's the theory behind it, its uses etc? I heard something about it, and I'm trying to get more info on it.

Thanks!

I've always considered the S-mount to be more of a transition position but some people use it as a variation of the standard mount. Basically from the standard mount position, swing/slide your left knee up into your opponent's right armpit. Then bring your right leg around sliding your shin past your opponent's left armpit so that your legs form an S.

S mount for armbars

The purpose of S mount is a setup for an armbar. From the mount position you bring, for example, you left knee up to the head, trapping his right arm. Then your right leg under the left arm, facing forward, bottom of you foot facing away form you. Thats the "S" position. This will allow for a quick transition to the armbar on the opponents right arm. You can also pivot quickly and switch you legs completely opposite and attack the other arm. Your weight is resting on the opponents chest, making it hard to bridge out, and you have both legs and one hand to use for base. My number one attack from the mount is using the "X" choke to set up the "S" mount and swing for the armbar. If the opponent defends well on the arm I am attacking, I pivot the "S" mount to the other side and get that arm.

Very effective especially when the guy on top has weight! When you are on the bottom and the guy on top has this mount (with control of your sleeves-it is very bad!)

Thanks guys!
I'm still having a hard time understanding the descriptions, although I think I have an idea. Anyone happen to have a picture of this?

As a transition, it looks like step four of this technique.

So you're leg that you swing up to be the top part of the "S", does it go under or over the opponents arm? Also, does it need to be all the way under his head?

The way I like to use it is a counter/reaction to my opponent's bridge/upa. If he bridges to my right, I move to the left. My left knee goes to the side of his head, by necessity, under his arm/shoulder. My right ankle slides up under his far shoulder. He ends up 3/4 on his side, facing away from me, and I'm in a very good position to armbar, choke, or even roll into a triangle choke.

My knee isn't under his head, but tight to it.

The image in the photo is the position in transition. If you were looking at it in isolation, it could be the guy in white has shifted his weight off of the head-side knee (from the position I described above) and has started the movement to swing that leg up for the armbar. In reality he's using it in a slightly different way.

Another S-Mount

BJJ instructors like to have different names for things. The S-mount described above was taught to me as "S-mount" and "High mount".

What J-J. Machado and Royce Gracie demonstrate in their respective books as an S-mount is a transition from side-control to mount. The move is acomplished by brining the legs to a kesa gatame position, posting the top leg, and swinging the bottom (extended leg) in an arc over the opponent's head, so that you end up mounted. The path of the leg moving from side-control, through the base switch, to mount, describes an "S".

This is a good no-gi armbar also, since without the GI and the in the mount the attacks are limited.
