ACCA Challenge Match Ladder System

This is an ongoing system. Anyone on the ladder can challenge within +/- 4 positions of their current position. The two opponents should agree on time and place, then email Charles (for a mass emailing) or mass email themselves allowing all of us to meet online to view the match, cheer, kibitz and chat.

The matches will be best of 4. Currently, the TC is G/14+1 allowing 4 matches in 2 hours. Colors will alternate and the lower ranked opponent gets white in the first match. Challenger must win to move up and the win moves the lower ranked opponent to 1 position above the higher ranked opponent. A draw doesn't change the rankings. Any program on the list that hasn't challenged or been challenged in 12 months will drop 1 position.
