■Half guard and beyond
DHC System's Masahiro Iwasaki's "Half Guard Principles" sold 400 copies in the first 24 hours after its release. The second edition, the Deep Half & Reverse Half edition, is now complete.

The theme of this tutorial is the "Deep Half," which is synonymous with Masahiro Iwasaki, the founder of DEEP HALF CLUB, and the "Reverse Half," which is derived from it.

The previous book, "Fundamentals of the Half Guard", explained the structure of the half guard and covered the basics in detail, with a focus on keeping the ball and controlling the opponent.

The biggest difference between the half guard and the deep half guard is that the deep half guard can only happen if you intentionally go for it yourself. It is difficult to pass from the deep half guard, but it is also a difficult position to control or sweep your opponent.

In this tutorial, Iwasaki explains how to disrupt your opponent by controlling the two axes: forward/backward and up/down.

How to trap and grasp the opponent's legs, the position of the left and right hands, how to take the lapel and how to apply force - each technique is explained in two axes.


■ If you want to be an intermediate or advanced skier, you must prepare for the deep half
Deep half is a special position, and once you are in the position, it is impossible to break through without knowing the release procedure. Also, there are few people who use it, and it is difficult to gain sufficient knowledge through practice in the gym.

However, if you are aiming to be an intermediate or advanced athlete, you cannot avoid the technique of passing from the top.
Even if you don't use the deep half yourself, this instruction manual will be useful as a strategy guide.


■ The meaning behind the two sides
This instruction manual includes offensive and defensive exercises for two positions: deep half (front) and reverse half (back).

The reverse half, which is the second half of the book, explains how to develop from the deep half position to the point where the opponent straddles your head. These two positions should be learned at the same time, and are an advanced version of the deep half.

In the reverse half offense and defense, scrambles are likely to occur, and you can learn the techniques to control the difference between winning and losing. If the top opponent avoids the deep half and gets over, there are many points where scrambles can occur, such as a stalemate and the timing to get over again from there, so you need to carefully control your opponent and win.


■ Generous provision of special skills
It also includes the bridge sweep, which is Iwasaki's specialty, and the "Iwasaki Sweep," which combines the opponent's action to defend against it.

The Eel Lock is the only joint lock that can be performed directly from deep half wrestling, and is also effective in no-gi wrestling, and can be performed from deep half wrestling with low risk.
This is a must-see technique for anyone learning the deep half.

This is the definitive instructional video for deep half and reverse half in Japan.
I hope you will learn the essence of this and apply it to your daily practice.
