Bughouse is an excellent 4 player variant that can be played with a different number of players, or (as a Bughouse variant) even a greater number of boards & sets than just two, if desired. Fwiw, I've seen on internet chat sites talk that Bughouse is hard for engines, as there are two boards & sets + drops, multiplying the possibilites compared to standard chess. If ever one of the two boards has a player sitting (refusing to move), however, the computer may then have an advantage if playing against a human on the remaining board (provided that person doesn't already have a big advantage).

From the wiki entry on Bughouse: "A valuation system, first suggested by FICS-player Gnejs, often applied to bughouse is pawn=1, bishop=knight=rook=2 and queen=4."

Any volunteers to create Game Courier preset for 2-player bughouse, like described in 'Bughouse per e-mail' section? Looks like a fun game!

The 'Bughouse Chess' book is now in print and copies can be ordered via amazon.de and bookstores. For more details see http://www.bughouse-book.com !

This site unfortunately is getting out of date, it for example still links to my old d2d4.de page which doesn't exist anymore for years now. I have mailed months ago about this.

There are many regional rules in this game. In our part of Germany and in Poland there is an interesting rule considering pawn promotion (called 'Grabschen', roughly translated taking away: If a pawn reaches the last line, the enemy team gets it, but the player owning the pawn promotes it by taking a figure of the partners enemy board. This leads to many tactical possibilties, like taking an checkmating figure (or the one that covers it) away. Besides that, we play our 'Tandem' without checkmating by dropping a figure, but with checking, and the first win ends the round.

we play htis game at lunch at my school every day. during exam week when we had a 2 hour lunch break we got 9 boards going at once. i t was crazy. the boards in the middle had more pieces available to drop than could fit on the board!! also, our rules of ending are different. you play to when the king is taken. then if your king is taken in bughouse our partner has 3 moves to mate his oponent to make it a draw not a loss. and in 3, 5, 7, 9 board etc game, when a king is captured i is passed to the middle so that if one of your partners gets maited, he can use the turn that he owuld normally have right before being taken to dtop another kind somewhere else. (those king dropping rulaes are very lax as someone once dropped their extra king to mate their opponent!!)

About pawn dropping: we have the rule that a pawn CAN drop in the first rank if agreed at start, and the fixed rule that a pawn can NOT drop on the 6th, 7th or 8th ranks. And only 'original' pawns have the 2-ranks starting movement. <p>Besides that, we also used to play four or six boards in a row. White pieces are always at the left, and pieces always move rightwards. Pieces from the last-right board used to be thrown to the first board causing curious jokes, for example about Queens' underwear while it's flying. <p>About kings, we used to end all boards when first king is checkmated.

I've played a bughouse-type game with 3 boards. The students who started playing it in the lobby of my dorm started out with about 4 or 5 people playing bughouse. This attracted attention and drew more people from the dorm in the next few days. Once there were at least 6 people, another board was brought out and they started playing 'crackhouse' (it was addicting like crack). The central board was the board for the more advanced player, and winning on this board would win the game for that team. The other way a team could win is if the 2 side boards are won for a certain team. The time limits were different for the central board than they were for the side boards. The central board was given less time, I think. But this would mean that timers were unnecessary for the side boards. I don't remember exactly how timing worked. Captured pieces from the sides moved towards the center, and captured pieces from the center went to either side depending on which player the central player decided needed the piece more. Kings were capturable (a captured king on the central board would end the game), and when a captured side king moved to the central board, the king in hand could negate a piece in hand from the opponent in the central board. Both pieces were removed from the game. This rule could be changed to something like 'king in hand can remove an opponent's piece on the board (except king), but not while in check'. The king in hand rules were not set in stone. It got pretty crazy. I played this game instead of studying for finals last year. Looking back, that was a bad decision. <p>I have to credit Nick for this game. He said that he and some friends invented it. If only I could remember his last name...

Bughouse has many regional rules, but most of the rules given on this page do correspond to the international and widely accepted ones. For tournaments you need to be a little more precise about the handling of some potential problems, but here I would just add that : - I never heard about 'serious' bughouse played without a clock or at a time control exceeding 5 minutes per player and per move. - Verbal communication between partners is always unrestricted, and is the absolute spirit of the game. So you can advice (or flame) your partner. And I advice everybody to keep an eye on the publishing of Georg's book, which will probably be the definite saying about bughouse !

<p>Please take a look at <a href='http://www.bughouse-book.com'>bughouse-book.com</a> <p>Imagine Anand,Leko, Kramnik and many of the other top chess players collaborating on one book ! Well that is what we did for bughouse chess - with many of the top internet (and European and US-gatherings) players contributing to create the first true bughouse book. <p>Coming 2005 ...

The way I play it, the player gets 1 minute for each move, if s/he exceeds that time limit, the opponet removes a pawn (or lowest value piece possible) and gives it to his partner. The player has now forfitted his move.

The way that I have always played Bughouse is that: A. Drops can only be done on your half of the board, B. No dropping as to check the king, C. First player to mate and his partner win. Rule A seems to take a little of the potency of drops away, but it's not that hard to move to the other side of the board.

I have also heard of this variant of chess being called transfer chess.

Hi! Good page, but the links are a bit outdated. Check out: thebugboard.net, bughouse.info for some good links and software to download. Also if you want to play bughouse or crazyhouse online The freechess server freechess.org is the place to be! the link http://www.bughousechess.com/ mentioned on the page does no longer exists.

The one thing I would correct is that in bughouse, you must press the clock before you pass the piece. Because your turn is not effectively completed until you press your clock you could still do something else (as is the case in blitz when touch-move is not in play). I have seen more than once what happens when in over-the-board someone takes a piece and then doesn't press his clock: the opponent may try to move but the player could claim, 'But I haven't pressed my clock yet.' Of course, in over the board play, if you press your clock you don't necessarily have to pass the piece...especially if you are playing with 5 people and the loser is out! Otherwise the page looks good! -LittleKarpov (Rated 2005 on FICS)

I'm an A-player (rating 1919) and the page is correct. Sam is not.

In real bughouse you are able to place a pawn on the first rank. What you need to do is to look into this game more and get the right facts.
