[quote=”lee_UK”]Index finger holds down the A string on the 2nd fret, your little finger holds down the D,G and B strings on the 4th fret, you just press your little finger across those 3 (DGB strings) together, and then only play those 4 strings, thats the easiest way to play a B chord.[/quote]

I agree but I use my ring finger across the D-G-B strings. It is basically the “A” chord moved up the neck 2 frets. You can move this finger positioning up and down the fretboard to make many other chords. It is a great tool for your inventory of chords.
