Covering (Defensive Strategy)
If a single checker is left uncovered the opponent may land on the checker, thus removing it from the field of play. This is known as “hitting”. When an opponent lands on a single checker, it is removed from the board. The checker is temporarily out of play until it can re-enter the game. Therefore, in order to avoid having the opponent land on single checker (and thus temporarily remove it from the board), at least two checkers must occupy a point (typically termed “covering”).
