If you want to learn how to execute certain moves, or to counter others,
like almost everyone would say is; learn from experience (Or if it's a specific
mod, then you could search for a teacher). If you are a Yellow belt
and are losing to black belts, the difference is not just skill, but experience.
Play more and develop your own game-play.
There are a large variety of mods and modes, having a tutorial that would
correspond to the game-play of all of them is not possible, so the tutorial provided
is a general tutorial that covers the basics of moving your character.
Having a tutorial for each of the dozens of mods is also an impossible endeavor,
as everyone plays differently in every mod. It would be too difficult or impossible
to create a default game-play to show all the newbies how to play every specific
mod, as this is overall a game of strategic skill.
