Grab your opponent's armpit in Sanda competition?

Sanda is a regular competitive sport. He wants to throw you, and you still have time to catch him, which means

He didn't move properly, or you fell down without reaction time. He dumped you. It should be your first time.

How to resist falling, all falling methods are to shift the opponent's center of gravity, so resisting falling is to try to stabilize.

Center of gravity, if you have the chance, you can punch him with hook or flat hook.

You can scratch his armpit, but it's really better to hit him in the ribs or hit him in the head.

Wear gloves in Sanda competition. I don't know how you tease him, but it's kind of funny. It could be him.

I think you don't respect him, or he is ticklish. In short, you should train well and prove yourself with your strength in the future.

It's gonna be okay.
