    Bughouse and Tandem Chess

    Introduction

    Bughouse Chess, and its close relative Tandem Chess, are played around the world under a number of different names: Exchange Chess, Pass-On Chess, Double Bughouse, New England Double Bughouse Chess, Siamese Chess (for Tandem Chess), and Tandem Put-Back. In the Encyclopedia of Chess Variants, Pritchard estimates that Bughouse was created in the 1960s. (I remember having played Bughouse in a Dutch chess club at around 1970.) The game has since became quite popular, with tournaments being heald consistantly up to the present time. There is even a Bughouse Newsletter, but I do not know the address. (Perhaps a reader can supply this information.)

    We will begin with the more popular Bughouse Chess and then discuss the rule changes that distinguish the older Tandem Chess variant.

    Setup

    Two Orthodox Chess boards are set up for four players as follows:

    Team B
    Player 3

    Team A
    Player 1

       

    Team B
    Player 4

    Team A
    Player 2

        Player 1 forms a team with player 2
    player 3 forms a team with player 4.

    Pieces

    The pieces are the same as those used in Orthodox Chess.

    Rules

    The game is played by two teams of two players each. This requires that two chessboards be placed side by side with partners sitting on the same side of the table (see above). For each team, one player plays with white pieces and the other plays with black.

    Each pair of contestants plays an Orthodox Chess game which has a special feature: All captured pieces are given to ones partner. Once received they become reserve pieces which can be dropped onto an empty square on the board to be used as ones own. This is done in lieu of a board move. (Compare Shogi.)

    There is one restriction on drops: A captured Pawn may not be placed on the 1st or the 8th rank.

    A Rook dropped onto either Rook home square is considered not to have moved; so one may castle with such a Rook. A similar rule applies to a Pawn dropped onto the second rank: The Pawn inherits the two-step-move option along with the risk of en passant capture.

    You may not advise your partner, but you can ask him to capture a certain piece that you need: 'Partner, I really need a Knight'.

    A gentleman's rule: In an unclocked game, a player may not delay his move beyond the time that it takes for his partner to make three moves. (This rule discourages the practice of perpetually delaying one's move in the hope that one's partner will capture a much needed piece. The rule is unnecessary, however, in a clocked game, as stalling in the presence of a clock is self-defeating.)

    The game may be scored in either of two ways, depending on prior agreement:

    1. The first mate or overtime (when using clocks) decides the match.
      
      
    2. The first mate or overtime (when using clocks) does not decide the match, and play continues on the remaining board. Captives in hand may still be dropped, but there is no way to acquire new captives. Once the remaining game is completed, points are counted as follows: 1 for a win, 1/2 for a draw, and 0 for a loss. The team with the most points wins. If teams score 1-1, the match is a draw.
    Note: A check by a line piece can be voided by dropping a captive between the checking piece and the King, whereas a check by a Knight cannot.

    Clock-play rules

    Bughouse is best played with clocks and with little time per player (e.g., 5 minutes). Clocks should be positioned so that all four players can see them clearly.

    One may not inform one's partner that his opponent's time is up (flag has fallen).

    There is no proscription on exactly when you must hand your partner the captured piece; it may be done before or after you hit the clock.

    Tandem Chess rules

    Rules are the same as for Bughouse Chess, except for the following ammendments:

    1. One is not allowed to give check or mate with a drop.
    2. The match continues until both games are completed.

    Bughouse per e-mail

    E-mail Bughouse requires only two players (North and South), as each assumes the role of a single set of partners. The game is played as follows:

    1. South begins by moving a white piece.
    2. North replies by moving a black piece followed by a white piece.
    3. South replies by moving a white piece followed by a black piece.
    4. Etc.

    This type of play gives the e-mail game a kind of 'synchronous' effect which the face-to-face version lacks. This serves to makes it yet another chess variant.

    2011-04-09 (zzo38) A. Black Verified as (zzo38) A. BlackNoneThe one with 'Bughouse per e-mail' should instead be called 'Synchronous Bughouse', since this is game that can also be played without mail or email, but is also the way to play the Synchronous Bughouse game over the slow communication channel by two players only.

    Here are some Bughouse variants by me: 1. Some possible turn variants (they can be played by 4 or 2 players, and it's possible to play these with GC): a. In each turn, player must move one piece on both boards (in any order), possible to make one or two drops. b. Player must chose one of boards to move or drop piece on it. c. Turn order: p1 moves/drops on b1, p2 moves/drops on b1, p2 moves/drops on b2, p1 moves/drops on b2, p1 moves/drops on b1... Turn variants, of course, have no advantage that original bughouse have: it can be solved. But even normal chess was not solved yet, and these will not be solved soon (if someone will try to solve them, of course). 2. Kings can be captured and dropped (it's still not allowed to castle trough check). Team loses when it have no kings (when it have king(s) in reserve only it also loses). 3. You gives captured pieces to opponent's teammate! In this game, there is no material advantage. Perhaps, it's better (for balance) to move black on one of boards first. 4. This variant was probably already invented before me as one of these many regional variants: pieces can be dropped only to starting squares of pieces of same kind. 5. Bughouse, combined with it's own 2-players variant Crazyhouse: after each capture, player must chose to give captured piece to teammate or leave for himself (probably, it's better to play it with shogi-like set). 6. And most unusual variant: Bughouse, combined with Alice chess! When piece moves, it appears on another board without changing sides (see Alice chess rules for details)! Of course, it's better to play this according to one of turn variants above, but it's possible to play with normal bughouse rules to: piece appears when move on corresponding board is finished, if square is occuppied, piece on that square gets captured (it's possible to capture king, and it's team loses).

    In Russia this variant is commonly known as Swedish chess (i don't know why, maybe, it was brought to USSR by Swedish players). Naming is, of course, not important, with one expection: i don't like name 'Siamese chess'! Siamese chess is Makruk (Makruk, of course, also can be played in Bughouse style, as almost any other chess or checkers-like game)!

    And who is inventor of Bughouse? Looks like, it's inventor is unknown. Interesting, did he knew about shogi when invented this?

    In my high school chess club back in the 1970s we used to play this with multiples of 4 players--up to 16 players. You pass pieces to your right and the player on the right end throws them to the player on the left end.

    It's a great game for a whole chess team to play one fast exciting game.
