is a one-way force, either towards the "home" side (where the team has their bags/kit), or "away". Other forces are "sideline" (force towards the closest sideline), "middle" (force towards the center of the field), "straight up" (the force stands directly in front of the thrower – useful against long throwers), or "sidearm/backhand" if one wishes their opponents to throw a particular throw. Another, more advanced marking technique is called the "triangle mark". This involves shuffling and drop stepping to take away throwing angles in an order that usually goes: 1) take away shown throw "inside" 2) shuffle to take away 1st pivot "around" 3) drop step and shuffle to take away 2nd pivot 4) recover. However, this marking technique is typically used to block long throws as well as force a certain side. Match-to-match The simplest defensive strategy is the match-to-match defense (also known as "one-to-one", "person-to-person", or "man defense"), where each defender guards a specific offensive player, called their "mark". This defense creates one-to-one matchups all over the field – if each defender shuts out their mark, the team will likely earn a turn over. The defensive players will usually choose their mark at the beginning of the point before the pull. Often players will mark the same person throughout the game, giving them an opportunity to pick up on their opponent's strengths and weaknesses as they play. Poaching Poaching is a term used to describe one or more players temporarily leaving their match up to strategically cover space in an otherwise person-to-person defensive scheme. Typical areas covered might be deep space (to defend long throws aimed at scoring quickly), near handlers (to narrow throwing lanes, making throws more difficult), or leaving players who are less likely to get the disc to help cover other areas of the field that are more likely to be directly attacked (such as moving closer to the disc when the disc is trapped on one side of the field). A common occurrence of poaching is when a player is accidentally open in a dangerous position. In this situation, it is common for another player to temporarily cover him defensively to avoid a fast score. This is common when the deepest person of the defense sees someone running past him, without a defender catching up to him, and it might be considered obligatory to run and cover the player open deep.
