When you use your raising block to block my forearm, since my elbow joint is free, I can bend my arm and drop my elbow on your chest. old saying said, "An elbow strike can be worse than 10 punches."I block your punch, you push my arm up higher. Now you have both arms up and I only have one. From this point, I can step behind you and shove to topple you over, because your center of gravity is very high, I can strike with my other hand, or there's all sorts of things I can do with my knees and feet towards your exposed legs, groin, and ribs.
In the following clip,
- He throw a right "fake" punch.
- His opponent uses right raising block.
- He use left raising block to raise his opponent's raising block.
- He then drop right elbow joint on his opponent's chest.
His high center of gravity give him a chance to drop down with his elbow strike. His opponent's raising block helps him to set up his elbow strike nicely.
