No one likes unfinished matches, but sometimes games get interrupted and cannot be finished in a timely manner. Especially in money games, no one wants their reserves tied up waiting for an opponent to reappear. At the same time, everyone wants to ensure that they get full equity, reflecting the current score and position in each game.
GridGammon developed the automatic match resolution (AMR) system to handle this situation. If you and your opponent cannot complete a match within a reasonable period of time, AMR will determine how rating points and/or cash stakes should be awarded.
Complete information about how AMR works is available on the GridGammon AMR page.
