About retreating to platforms:
I've seen this strategy in a few matches where you retreat to the platforms when in a bad spot, play patient from there on and use your threat zones from the platform to force the opponent to respect your landing when going back to the main stage. Ideally you would be able to go from disadvantageous positions back to neutral this way. This seems particularly applicable if you gave up space to increase your chance to win neutral but are cornered now, because compared to other disadvantageous situations, there is less of a risk of getting hit while going to the platform.
So far, I've mostly seen Fox or Sheik do it, but I think it is a very general concept, and Marth, while not as good at using platforms, should also be able to use it against characters that aren't as good as threatening the platforms or not as fast. I could imagine that it is at least somewhat useful against anyone but Fox and Marth.
About shield:
I've been wondering what the key criteria that decide when shielding is more acceptable and when not. Obviously there are these situations where you are in a bad spot and have to shield to avoid getting hit, but I'm talking about shield being an important neutral tool.
My biggest concerns were getting grabbed and not having any cues, which, if registered, allow to move out of shield for free. Most characters generally want to use attacks with low enough cooldown so that moving out (WD OoS, for example) on reaction can already be caught by an immediated followup attack, so that would be problematic.
The character that shielding would be most useful against, according to that logic, would be Peach, because she is slow, has little grab range, and while float-cancelled aerials are good on shield, they aren't available immediately again and you can move out on reaction against jab, down-smash or down-tilt.
I've also seen people having success with shield against Fox players by using preceding movement or even a turnaround and shield DI, to make late aerials hit early on shield and shieldgrab them, or shieldgrab crossups because you are facing the other way all of a sudden. I'm still unsure if this is actually an important tool in the matchup or exploiting bad play from Fox's side. My guess is that Fox shouldn't use dash short hop aerial as much anyways, and that there are also timing differences, but Fox players are also forced to use these aerials from time to time, so it might be good as a rare mixup.
Thoughts about this?
Thanks for answering my questions all the time, I feel like it helps me to develop my understanding of the game
