Two-handed backhand
On the left hand your base index knuckle and heel pad will be on bevel #7 (or #3- blue colors).
Right hand base index knuckle and heel pad will both be placed on #2 (or #6- feel the bumps- this is also the continental grip).
The two-handed backhand is often easier to learn than the one-handed so many people use it. It offers great stability and control for players.
