Asus2 guitar chord
An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.

How to play Asus2
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
Asus2 has 6 of them, on the middle four strings, strings 5-4-3-2-1, the top four strings, the bottom four strings, strings 6-4-3-2 and strings 6-5-4-3-2, from the 2nd fret up to the 4th — every inversion the chord has: A in the bass and E in the bass. The one to learn first is the A shape at the 2nd fret, which is the easiest grip here.
Start with x02200 — no barre and 3 open strings. 2 of the 11 shapes here sit in open position. 4 of the 11 need a barre. Together they cover the neck from the 2nd fret to the 14th.
