How about some anti-chain grabbing advice, because I'm pretty sure you play falco:
(btw, I'm only pretty sure about these, so if anyone wants to correct me that would be great)
vs. Marth
0-7%, Marth doesn't have a true chain grab on falco (as long as you don't DI). If he tries to forward throw > regrab, I believe
you can shine before he regrabs.
8-18%, Marth has a true chain grab on falco, but if you do slight DI behind him (about +/-20 degrees from straight up) it can be really difficult to regrab you. Try DI'ing so that you would land directly on Marth's head.
19%-28%, Marth has a true chain grab on falco, but ONLY if he does a pivot regrab. If he tries for a regular regrab, and you don't DI, you should be able to shine just before he grabs you.
28%+, If you don't DI, Marth has no true regrab.
vs. Peach
40%-100%, Should be a true chain, so you're pretty boned. Try mixing up your DI, or if you're on a map with platforms, try DI'ing towards one.
100%-120%, If she's still going for a chain grab after 100%, I'm pretty sure if you don't DI that you can shine before she regrabs you.
