You just B-Aired.

[Geou]

And it either whiffed slightly in front of your shielding opponent, or it hit their shield. What are all of the options you have now?

There's obviously the classic F-Smash, where if they went for the shield grab they'll be eating a nice fire explosion to the face.

You could go for another short-hopped B-Air to continue the shield pressure, but I think this option is a little weak.

You could run in for a grab/pivot grab, which works well as long as they don't expect it and attack you/grab you first.

Anything else?

Dair

SH Double Bair

Stop attacking them and retreat

U-air, is another good aerial to use (d-air is more useful, harder to Shieldgrab), Cape is semi-good gives you a bit of upwards momentum, and you reverse them if they go for a Grab.

Would up B be another good option?

Either what Monk said, or run away throwing out a reverse fireball to cover my ***.

if you whiff a Bair...up-bing could work but if they powershield the first hit they can shield through the whole thing and then you would be wide open...so I would say it's viable just not always trustworthy
