-Spacing with True Pivot and Foxtrot:THANK YOU PHANNA!
What is it:
Foxtrot(Part 1 and 3): Initial dash animation that results in some sort of sliding stop for each character.
True Pivot(Part 2): For a very small amount of time during a pivot (turning your character around to face the other direction) it is possible to initiate anything that you want (smash attack, jump, shield, crouch as if you are standing in the neutral position normally.
How it works: When you initiate a foxtrot, quickly press the same direction followed by the opposite direction. The timing is easiest with Marth so try practicing with him first. So basically, you will see Sonic slide forward, stand straight up and then turn the opposite direction and slide again.
Assume forward is right and backwards is left. IF you started by standing still and facing the right the timing is:
1.........2...3
Forward............ Forward....Back
If you wanted to do this over and over again the timing would be
F.........F....B.........B...F...........F....B
1........2-3............4-5.............6-7
As you can see the timing gets consistent once you do the initial movement. Be patient.
Use: I know... you're thinking: There's no wavedashing in brawl, stop trying to include it dNES. Well, honestly... this is probably the closest thing we have. All characters can do it, but for some it's better than others. Sonic's amazing grind (foxtrot) distance allows him to really bail out of a tight situation only to turn around and instantly take the offensive. For a character with bad priority this is pretty viable. I personally come back with either a grab or a dash attack but honestly it's up to you. Just remember that you can't do EVERYTHING from a foxtrot. You can however do the following:
spin dash (pop) (w/ or w/out shield cancel)
grab
dash attack
usmash
you can even roll forward (but not backwards)
Prior to this technique, grinding really wasn't anything more than a fancy way to release a dash attack or spin shield. Now though, you can really control just how far you move with that second foxtrot. The timing of the first is too short, plus you want to get out of there so you can avoid the attack. With grinding though, you can cover even more distance as you come back towards your opponent. Usually you will find yourself sliding past your opponent if you miss, so sometimes you need to ease off on the foxtrot by just barely changing directions.
*You don't see me being to precise (applying grind) with this in most of my videos. That's because I'm online and the input lag is usually too large to make these fine corrections with the grind. Intead it's easiser to try and control the initial force of the second foxtrot.
