Tiger Knee

The Tiger Knee, also known as "Tiger Thrust" or "Tiger Knee Crush" in Street Fighter IV, is one of Sagat's special attacks in the Street Fighter games.

Description
Executed in a similar way to that of Tiger Uppercut (except for the Street Fighter II series, where the player must input a diagonal half-circle forward motion) with a kick button used instead, Sagat jumps forward and rams into the opponent with his knee, hitting twice.

Origin
The move is based on an actual Muay Thai move (Flying Knee) and, in the original Street Fighter, it actually resembled a realistic Flying Knee attack.

Tactics
It can be used as an anti-air, combo ender, or as a far punish; in Street Fighter IV, it has armor breaking properties and its EX version has quicker recovery. However, if the opponent blocks, Sagat will be left wide open for counterattack.
