A term which came from the Virtua Fighter community, but, for various reasons, including David Sirlin's Web Articles/Book on Playing to Win, it has
spread to all fighting games.
Yomi is a
Japanese term meaning "Knowing the mind of the opponent", and is essentially an intangible asset required in fighting games. It's the ability to know what your opponent is going to do, and act appropriately. Whether you achieve this by "conditioning" the opponent to act one
way, and then acting in another way, or simply
work your way into the head of your opponent, yomi is just that: the ability to know what your opponent is going to do.
I got owned by an insane Akuma rushdown. He kept hitting me with
flip throws and
flip kicks, so I decided to shut him up with a wake up Shoryuken. He parried it and punished with a Raging Demon! Talk about yomi.
