Bsus2 is B, C# and F# — B with the third replaced by the second.
It sounds open, and neither major nor minor. With no third it works over either quality, which is why strummed parts lean on it.

| B | C# | F# |
|---|---|---|
| 1 | 2 | 5 |
Suspended — it hangs until something moves.
Also written B2 or B suspended 2nd. The same chord either way; which spelling you meet depends on who wrote the chart.
Bsus2 in root position puts B in the bass, which is the chord as it is spelled: the note it is named after underneath everything else.
6 of Bsus2’s 8 common shapes do this: x24422, 74467x, 7xx677, 799x79, x-x-9-11-12-9, x-14-11-11-12-14.
Start with 74467x — no barre and low, at the 4th fret. None of the shapes for Bsus2 uses an open string, so every one of them is movable; the lowest sits at the 2nd fret. 4 of the 8 need a barre. Together they cover the neck from the 2nd fret to the 14th.
