What is Double Chess?
Double Chess, or Bughouse, is an exciting, fast-paced chess variant – played in teams of two, with pieces exchanged between the two boards. We’re excited to host a one-night double-chess tournament at ACC this year!

Format:
5-Round Swiss (double rounds, switching colours)
Team Seeding / Pairings:
Swiss pairings, using the average rating of the two-player team. In each team match, top-rated plays top-rated.
Time Control:
Game in 5 minutes (flat, with no increment)
Rules of Bughouse:
There are several variations of Bughouse Chess. In this tournament, we will be allowing pawns dropped on the 7th, drop-checks, and drop-mates. Pawns may promote (although they can’t be dropped on the 1st or 8th ranks), but captured promoted pawns go back to being pawns.
Touch Move:
The games will be played with standard tournament rules of touch move and release move. Reserve pieces are “touched” when they make contact with an empty square.
Communication:
In keeping with the spirit of Bughouse, players may communicate; however, they may not directly help each other. Legal communication is limited to:
– requesting a piece – “Need knight!”
– requesting avoiding giving piece – “No diagonals!”
– recommend stalling / remind partner of clock situation
Under no circumstances may players feed their partners moves or ideas, which could be as elaborate as “take twice on f7, check on h6, then g7 and mate” or as simple as “check (him)!”
Entry fee / Prizes:
There will be a nominal entry fee of $5/player or $10/team, equal to our usual casual drop-in price. (Entry is free for current ACC members.) There are no cash prizes, but we will provide trophies to the winning team!
