With or against the grain of the grass

[dkerby]

When chipping or pitching from heavy grass would you
change the hinge action for with the grain of the
the grass as to against the grain of the grass.
What is the best hinge action for the two shots?
Would you use "club in palm of hand" for the shots?
Seems like the longer swing to get the ball out of
heavy grass requires the club to be in the fingers of
the grip. Is this correct?
