 Defensive strategies are often employed to slow down game play or force opponents to make difficult decisions, such as throwing a blocker bag that rests in front of the hole.This forces an opponent to either slide through the blocker bag to reach the hole, throw another blocker behind the bag, or attempt a riskier airmail shot over the bag (throwing directly into the hole without touching the board).An uncommon version of scoring also includes a 2-point option.
