Bughouse chess

Template:Infobox Game Bughouse Chess, Doubles Chess, Siamese Chess, or Tandem Chess is a variation of chess played with two teams of two people with two chess boards.

Team members sit beside each other playing opposite colors. Each player plays his opponent as in a standard chess game except that when pieces are captured they are given to the teammate. The teammate can then decide to place the captured piece almost anywhere on the board in place of a regular move (as in shogi). Team members have to work together, and against a clock, to win. The first board to lose decides the match and if a draw occurs on one board the entire game is a draw.

There are two main variants of Bughouse Chess: Bughouse and Tandem Chess. The main difference is that in Tandem Chess, one cannot use pieces to check or to mate. Also, in Tandem Chess one cannot place pawns on the 1st, 7th or 8th rows if playing white or on the 1st, 2nd, or 8th rows if playing black. In Bughouse anyone can drop any piece anywhere except for pawns on the 1st or 8th row.

Both Bughouse and Tandem Chess use chess clocks to prevent players from waiting indefinitely for a piece (waiting for pieces is considered perfectly acceptable, see Bughouse strategy below). Tandem Chess is usually played with 5 minutes per player, and Bughouse 3.

Though opinions vary about this, it is generally accepted that at least some form of discussion between teammates is allowed. Any Bughouse variant allows players to ask their partners to capture a specific piece for them.

Bughouse strategy

One of the main ingredients of any bughouse game is time. It is not uncommon for one player to completely stop moving because he knows that any move he makes will result in him getting mated the next move. It is even possible for this to happen on both boards. For example: I am one move away from checkmating my opponent, so he is not moving. However, my teammate is also not moving because any move on his part will result in checkmate. The game now turns into a game of sitting, called a 'Sitzkrieg' (after the German for Sitting War). The game is now decided by whether my teammate or my opponent has the most time left on their clock, because if either runs out of time he will be forced to move and will immediately lose.

Another very important aspect of Bughouse is player communication. It is customary to announce any big gains or losses ("rook in 3!") and to ask for specific pieces while listing their result ("pawn is rook!"). If you do not do this you might very well find that your partner loses because he was unable to plan ahead for any incoming pieces.

Where to play

There are two main alternatives for playing bughouse: Over the Board (OTB) or online. OTB simply means the four players are playing face to face at the same table. OTB bughouse is often played at large chess tournaments between rounds or at chess clubs. Online bughouse started around 1996 when the variant was added to Internet chess servers. Since then the vast majority of matches have been played online.

The most popular place to play online bughouse is the Free Internet Chess Server: FICS (http://www.freechess.org). The most popular client program for playing online is Thief, which was written by a strong bughouse player. Other clients such as XBoard and Winboard also offer nominal Bughouse support.

It’s also possible to play bughouse on the Internet Chess Club: ICC (http://www.chessclub.com). However both the quality and quantity of bughouse matches there is lower than on FICS. ICC is a commercial venture which currently has a membership fee of $50 US per year.

For those who prefer peer-to-peer or local area network (LAN) games, the Net Blitz 2 (http://www.netblitzchess.com) bughouse client is freely available for download.
