Morote-Tsuki is the double punch of Karate. It involves simultaneus punches to chudan. It torpedoes your guard and has a very limited range of application (such as using one punch as an hard block, which can lead to injury). This technique is more of an exercise and shouldn’t be attempted in combat.
