Lemme dig into my cache of borrowed knowledge. This is what I asked Taj:
1. How do you deal with pressure? It seems like unless you're playing Fox or the like, there's always going to be a character faster than yours, especially in matchups like Marth against Falcon. How do you go from being on the back foot to setting up an offense?
This is what he answered:
1.) Stay calm, try to read their movements, and find some kind of pattern or tell in their attacks. If they're just laying on the pressure, but waiting until you bite on their dash dances, then wait for that tell and assume they're going to move away and adjust your attack to cover their escape. Otherwise, using moves that force the player to slow down, or reconsider what they're doing are great ways to take the offensive. As Marth against Fox, usually moving into Fox with well spaced aerials or dashing down tilts, slowly forcing him into a corner works pretty well.
Against Falcon, kinda the same thing, but without a projectile to spam and a longer dash dance, so you just have to adjust accordingly. Usually with Fox, you have up throw pressure when you finally catch him, but Falcon you usually have to rely on tech chases, which is fine.
