Answer 2

If you want to be your best at chess,do not play bughouse.Ask anyone who is in to chess,you will find most say do not play bughouse.

Answer 3

Monkey's sorta got it right...it's played with clocks (everyone gets 5 minutes to make all their moves). And you play to checkmate. Usually then you have two people about to be mated just sitting there waiting (on opposing teams) till one or the other's flag falls. Some people stay that you're not allowed to stall like that, but...I don't really know how they could enforce it.

Answer 4

There are 4 people total. Each pair playing a different color (if you are black then your friend has to be white, if your opponent has to be white then and your friends opponent has to be black or vise versa). When you capture your opponents pieces, you can give them to your partner to use (since you capture white pieces and your friend is playing white). You can use one turn to put a piece on the board after that your turn is over. The winner is the side that has the most points worth of pieces captured wins (queen=9 points, rook=5points,, knight and bishop=3 points,, and pawn=1 point).

Answer 5

Bughouse is a chess variant played on two chessboards by four players in teams of two. Each team member faces one opponent of the other team. Partners sit next to each other and one player has black, while the other has white. Each player plays the opponent as in a standard chess game, with the exception of the rules specified below.[2]


[edit] Captured pieces
A player capturing a piece passes that piece to the partner. The partner keeps these pieces in reserve and may, instead of playing a regular move, place one of these pieces on the board (as in Shogi and Crazyhouse). Pieces in reserve or on deck may be placed on a vacant square, the exception being pawns which may not be dropped on the first and last rank. Dropped pawns may promote, but convert back to pawns when captured. In play over the board, a promoted pawn can be put on its side to indicate promotion.[3] A pawn placed on the second rank may move two squares on its first move. The reserve or stock should be kept in front of the board, always visible to all players of the game.


[edit] Clock and completion of a move
Bughouse chess is usually played with chess clocks to prevent players from waiting indefinitely for a piece. Clocks are placed on the outside so that each player can see both clocks. At the start of the game, the players with the black pieces start the clocks simultaneously. Bughouse is usually played using clock move, which allows touching of pieces. A move is completed only when the clock is pressed. Touch move is practised to a lesser extent.[4] When used, it applies to pieces in reserve as well; they are considered dropped after contact has been made with an empty square.

Bughouse can be played without a clock, but then there is usually a rule preventing a player waiting for pieces (stalling or sitting) indefinitely. One rule states that players may not delay their move beyond the time that it takes for their partner to make three moves.[5]


[edit] End of the game
The match ends when either of the games on the two boards ends. A game is won when one player gets checkmated, resigns, forfeits on time or when an illegal move is made in which the offending side is caught. The match can be drawn by agreement or when two players run out of time simultaneously. Depending on (local) rules threefold repetition applies, in which case the reserve of pieces is not taken into account.[6]

Alternatively, when one board finishes, play can continue on the other board. In this case, pieces in reserve can still be dropped, but no new pieces are coming in. The outcome of the match is then decided by adding the score of the two boards.[5]


[edit] Communication
Partners are normally allowed to talk to each other during the game. They can for instance ask for a specific piece, for more trades, ask to hold a piece, suggest moves or ask their partner to stall. Shouts like "Gimme a knight, it mates!" or "Queen at any cost!" are common, and can lead to seemingly absurd sacrificial captures on the other board. It is however not allowed to physically act on the other board.[7]


[edit] Variations
Bughouse comes in many variants, especially in the way drops are handled. Examples include:[8]

Pieces cannot be dropped with check and/or checkmate. This variant is not uncommon in Europe and is sometimes referred to as tandem chess.[9][10]
Pieces can only be placed on the player's half of the board.
Play continues until both games are complete.
Kings can be captured and the game continues until one team has all kings on the board.
Pawns cannot be dropped on seventh (and sometimes sixth) rank.
Pawns may be dropped on the first rank.
It is possible to play the game with just two players (one per team) by having each player move on two boards. Analogous to simultaneous chess, this way of playing the game is referred to as simultaneous bughouse. It can also be played with just one clock by playing the boards in a specific order (WhiteA, WhiteB, BlackB, BlackA) and pressing the clock after each move. This variation is suitable for play by mail.[11]

Bughouse can be played with three or more boards. The game is played in exactly the same way as normal bughouse with boards placed with alternating colours and two players and one clock per board. On capturing a piece however, the player has to decide which player of the team will get that piece. In three board bughouse chess the middle player is the key since he gets material from two boards, but has to decide how to divide the captured pieces.[12]


[edit] Strategy

[edit] Material
In chess a minor material advantage is important as when material gets exchanged, the relative advantage becomes larger. Because new pieces come in, there is no endgame play in bughouse and material is therefore less important. It is common to sacrifice pieces in bughouse while attacking, defending or hunting down a certain piece which the partner requires.[12]

A scoring system to evaluate material is to add up the piece values of the material on the board. In chess, when a pawn equals one unit, a bishop or knight is worth about three, a rook five and a queen nine. These values are a consequence of the difference in mobility of the pieces. In bughouse piece values differ because pieces in reserve essentially have the same mobility as they can be dropped on any vacant square.[13] The pawn relatively gains importance in bughouse chess, its very limited mobility does not handicap reserve pawns. Pawns can be dropped onto the seventh rank, one step away from promotion, which again adds to their importance. Long range pieces like the queen or the rook lose relative value, due to the constantly changing pawn structure. They are also more likely to be cornered in.[14] A valuation system often applied to bughouse is pawn=1, bishop=knight=rook=2 and queen=4.[15]


[edit] Coordination
Captured pieces are passed on and thus what happens on one board, influences what happens on the other board. It is therefore natural for team members to communicate during game play. A common request of an attacking player would be "trades are good", while players in trouble would ask their partner to hold trades with "trades are bad". Equally a player can request a piece e.g "knight wins a queen" or ask to hold a piece e.g. "rook mates me".[16]

Another common situation in the interplay between the two boards is a player not moving, also called sitting or stalling. This can happen in anticipation of a certain piece or at the request of the partner. Suppose a player is under heavy attack, and an additional pawn would mate him. When the partner cannot prevent giving up a pawn on the next move, sitting is the only strategy. It would of course be perfectly logical for the attacker to sit as well, waiting for a pawn to come. The situation, where diagonal opponents sit at the same time is known as a "sitzkrieg" (after the German for sitting war). The difference in time between the diagonal opponents will eventually force one party to move. This diagonal time advantage is more important than the difference on the clock between opponents on the same board.[17]

Apart from this active communication, a good bughouse player tries to coordinate silently by keeping an eye on the other board and adapting moves accordingly. This can mean as little as glancing at the other board before trading queens, or as much as playing an opening adapted to the other board.[18]


[edit] Attack and defense
Attacking the king can mean checking the opponent but also controlling vital squares around the king. It is an essential part of bughouse gameplay. From a player's perspective, attacking the king has important advantages as opposed to defending or attempting to win material:[19]

Because of the possibility of dropping pieces, successful attacks in bughouse can quickly lead to checkmate.
The attacking player has the initiative, he is the one who controls the board, while the opponent is left to react. This has also important consequences for the other board.
It is easier to attack than to defend. A defending mistake can have bigger consequences than an attacking mistake. Thus, the defender needs to be more precise, which in turn can lead to a time advantage for the attacker.
It is common to sacrifice material to build up, or sustain an attack. Characteristic for attacks is the so-called "piece storm", where a player drops piece after piece with check. Contact checks, those that force the king to move, are especially important. They can be used to drive the king into the open, away from its defenders, while it prevents the opponent of putting new material on the board.[20]

Partner communication is essential in a good defense. When one partner is under attack, the other partner should be aware of which pieces hurt most. Sitting strategies might be necessary, and it is therefore important to play the defense fast. Accepting a sacrifice can be lethal. On the other hand, it results in the attacker having a piece less to play with, with the defender's partner having a piece more. Sacrifices therefore give the partner of the defender an opportunity to take initiative.[21]


[edit] Opening
There are significantly fewer bughouse openings than there are chess openings. Many chess openings create weaknesses which can be easily exploited in bughouse. It is for instance not recommended to move pawns other than the d and e pawn.[22] Bughouse openings are generally geared towards dominating vital squares and fast development. Captured pieces become available after the first few moves and it is important to develop at this stage as there is often not enough time to do so later. Development also helps to defend against early piece drop attacks.[23]

In typical chess openings, kings castle. For all but expert players, this is generally not recommended in the opening stage of a bughouse game. A castled king is trapped on one side of the board, and is therefore inherently harder to defend. There are also fewer escape routes possible.


[edit] Notation and sample game

Example bughouse game.The algebraic chess notation for chess can be used to record moves in bughouse games. Different notations for piece drops are possible.[24] The internet chess servers FICS and ICC use the at-sign @, as in N@f1 (knight drop at f1), Q@e6+ (queen drop with check at e6) or P@h7 (pawn drop at h7).

Because of the fast pace in which the game is played, bughouse games are rarely recorded in games played over the board. With the arrival of online chess it has become possible to systematically record games.[25] The format in which this is done is the bughouse portable game notation (BPGN), an extension of the Portable Game Notation for chess.[26] Software, such as BPGN viewer can be used to replay and analyse bughouse games.[27] Below is an example bughouse game in the BPGN format.

[edit] Where to play

[edit] Over the board
Little is known on the history of bughouse, but it seems to have developed early 1960s.[28] It is now quite popular as a diversion of regular chess in local chess clubs throughout Europe and the US.[28][29] Grandmasters such as Levon Aronian, Joel Benjamin, Yasser Seirawan, Andy Soltis, John Nunn, Jon Speelman, Sergey Karjakin, Michael Adams, Emil Sutovsky and Michael Rohde have been known to play the game.[28][30][31][32][33][34]

With the absence of an International Federation, competitive over the board bughouse is very much in its infancy. There is also no world championship. A few countries do organize bughouse tournaments within the national chess federation. Examples include:

The yearly international chess festival Czech Open in July features the Czech republic bughouse championship.[35]
Yearly, USCF organizes bughouse tournaments as part of the National Junior High (K-9) Championship and the National High School (K-12) Championship.[36][37]
Other tournaments are organized privately:

One of the largest international bughouse tournaments is the yearly tournament in Berlin.[38] Going into its sixth edition, it is popular among top players from FICS. Grandmaster Levon Aronian took part in the 2005 edition of the tournament and took the second place with his teammate Vasiliy Shakov.[39]
Since 2000 there has been an annual bughouse tournament in Geneva, attracting the best European players.[28][40]

[edit] Online
Bughouse can be played online at chess servers such as FICS and ICC since 1995.[41] Fics is currently the most active server for bughouse, attracting world's best players. These include Levon Aronian, Maarten Aronsson, Igor Bjelobrk, Jeremy Keller, Kazim Gulamali, André Nilsson, Peter Minear, Linus Olsson and Justin Tan.[42]

The game is played online in the same way as over the board, but some aspects are unique to online bughouse. In games over the board, communication is heard by all players, while in online bughouse it is usually done via private messages between two partners. This makes communication a more powerful weapon. It is also easier to coordinate as the second board is more visible on the screen than over the board.[43] The time aspect is altered due to existence of premove and lag. The latter can influence the diagonal time difference significantly, and it is good sportsmanship to restart the game when this difference gets too large.[44]

ICS compatible interfaces particularly suitable for bughouse include Thief and BabasChess. They have the ability to display both boards at the same time and store played or observed games, they also have partner communication buttons and a lag indicator. Special Xboard compatible engines have been written that support bughouse, examples are Sunsetter, Sjeng and TJchess.[45][46][47] Although much faster than humans, they lack in positional understanding and especially in coordination and communication, an essential skill in this team game.[
