“If you’re new to World Chase Tag, here’s how it works”: QUAD - The playing area (in the UK, the old-school name for a playground is a quad). EQ (EVASION QUALITY) - A hypothetical value representing how much protection an obstacle (or area on the Quad) provides for the Evader. The higher the EQ, the more the protection. DTR - Or “Disputed Tag Review”: the chaser or evader can request a DTR when they feel that the referee call is incorrect. HERDING - A technique used by the Chaser to corral the Evader into areas of the Quad that will make it easier to make a Tag REVERSE HERDING - A technique used by the Evader to draw the Chaser into areas on the Quad that are harder to make a Tag THREADING - Diving or sliding though a tight space on the Quad, like through the Ridge or Loading Bay IDLING - A technique used by the Evader to hide behind a high EQ obstacle and waste the Chasers time / run down the clock while expending the least amount of energy SPIKE - A Chase that lasts less than 5 seconds TAILING - A technique used by the Chaser where they follow the same path as the Evader (generally considered an inferior strategy). SUDDEN DEATH CHASE OFF - A Sudden Death Chase-Off consists of two 20 second Chases where each team gets to Evade. The team that gets the longest Evasion Time wins. If a winner is not decided after one round of Sudden Death (for example, if both Chases end in an Evasion), the process is repeated.
