What has a head but can't move
COINS HAVE A HEAD AND THEY CAN'T MOVE IT.
When you stop and look, you can always see me; if you try to touch you can't touch me; I can't move, but as you near me, I will move away from you. What am I?
I play chess, I am the best, I will only move faster but there is be one skill I can't master.
Who am I?
