There is one special move in every stance.
The blue special/lunge: crouch + forward + attack
The backstab: back + attack when the opponent is behind you.
Blue swings are chainable, so you can do pretty neat combos.
The yellow special (a.k.a the blender, death from above = DFA , the butterfly etc.): forward + jump + attack while keeping your aim at the opponent.
Yellow backslash: same as the blue backstab
You can chain attacks... and execute 3 random swings normally.
Red special (a.k.a death from above = DFA): attack + jump when your swing is halfway done.
Red backsweep: same as the yellow & blue moves.
Chaining is a bit tougher. (Only 2 swings normally.) But you can chain 3 swings with little effort : f.ex forward + forward + left & forward
Forward + left & forward + forward won't work though. Experiment with it and you'll figure it out.
Hope this helps get you goin'
