Pushback

Pushback is a mechanic in Street Figther Games

Description
Pushback is used in Street Fighter games for a number of reasons that can include:
 * Make attacks negative in terms of Frame Data safe on block, on the example Ibuki's sweep is -7 in Street Figther X Tekken but the pushback makes it hard to punish. Especially if the attack is blocked at the upper end of it's range.
 * Prevent Infinites. Pushback is used on attacks that are positive on hit to force the comboing character to use a different longer range attack that is usually not as positive.
 * Reduce Pressure, a prime example is Cammy's jab in Street Fighter X Tekken was capable of pressuring enemies for a very long time due to positive safe data. In the latest patch, the 2013 version, it was given a rather high amount of pushback on hit and block to reduce effeciveness.
