For the G chord there are two fingerings listed.
The one in black is recommended. The one in red should be
avoided if at all possible. The one in black may seem more
awkward at first only because you are using your 4th finger,
which is your weakest finger. There are plenty of guitar
players that use the red fingering. One good example for
not using it, is switching between a G and a C chord. It is far to much work to use the red.

is not touching the first string.
