Hae Sul 2: Gae-Baek drop takedown

In General Choi's books the double arc hand block is portrayed as catching a frisbee or throw pillow -- something that got a chuckle out of me the first time I saw it. Here I'll analyze the first time the movement appears in Gae-Baek and get something else out of it. The set is:

• Front stance rising block 
• Maintaining stance, low block
• Maintaining stance, double arc hand block
• Lift and bring in front foot to bending ready stance A

Of note, this is the first time in the ITF forms that a bending ready stance is not followed by a kick. In my club we tend to turn an extra 45-degrees as we perform the stance, in preparation for move 9.

A common interpretation for the last two moves is a two-handed "push" followed by a sweep. To avoid retreading old ground here's a different application, shown in the combined gif below:

Details:

• Assume an opponent grabs you. Use the rising block as an upward strike to their jaw (not in the gif) as you grab a hold of their wrist with your reaction hand.
• Use the low block to crank their arm
• Continue the crank into the double arc hand block. The top arc hand strikes the opponent's jaw
• You can use the bending ready stance as a knee strike to the back of the head, but the interpretation I like is stepping behind your opponent and dropping to one knee, throwing them to the ground.

There are a couple other uses for the rising block. In the form you move backwards into it: it could be that your opponent is doing a grab-and-punch to the head and you are defending (a rising block, properly used, makes a good round punch defense). Another option is that your opponent is doing a double grab, and the rising block is breaking one of the grabs. Something similar is shown in the images below.

Left: rising block against a round punch. Right: rising block and low block against a double grab.
