Appeals Committee. Disputed situations in tournaments.

Shevanisian, you are fundamentally wrong. Here's how it works: either you play the endgame well, or there's simply no point in meticulously planning chains or calculating moves. This is especially true for HL+U templates, which you often play yourself. If you don't want your opponent to spend a long time thinking, either concede or offer them a plan for winning (this isn't a joke; some people actually do this). Or simply suggest saving the game before the Final Battle. Rushing a player during the Final Battle is, frankly, just bad manners.
