Tech-chasing

Tech-chasing is the act of following or predicting an opponent's tech in order to attack them before they can respond. Because a character's tech animations have small windows of vulnerability before a character can shield, sidestep, dodge, or attack, it is possible to read the direction of a player's tech and punish the lag with an attack, jump-canceled grab, or projectile.

Some characters are able to incorporate tech-chasing into a chain grab sequence. A classic example is Captain Falcon's up throw against fast-fallers. After he throws, Captain Falcon can gain another grab by successfully tech-chasing his enemy. A well-known example in Brawl is Snake's down throw. During the animation he lays his opponent on the ground and after the throw is over, if he can predict his opponent's roll, he can tech-chase them into another grab. Tech-chasing is much easier to do on characters with short tech rolls (such as Olimar) than those with long tech rolls (such as Zelda).
