How to play F♯dim7 on guitar

Shape 1, 2-0-1-2-1-2, reading from the low E string on the left:

Lay your index finger flat across the 3 strings from the D string to the B string at the 1st fret.
Middle finger: low E string, 2nd fret (F♯).
Ring finger: G string, 2nd fret (A).
Pinky: high E string, 2nd fret (F♯).
Let the open A string ring (A).

Only part of the finger needs to press here, so flatten just the tip section across those strings and keep the rest of the hand relaxed.
If an open string sounds dead, a fingertip is leaning on it. Come down more on the tips, with your knuckles bent.
This shape uses your pinky. It feels weak at first; press with the tip and let the finger stay curved.
