This reddit page has plenty of good advice, and mentions a (strong player's) opening repertoire (section "My Opening Systems").
Basic setup: 1. d4 ... 2. g3 ... 3. Bg2 ... 4. h3 ... 5. Nf3 ... 6. Bg5 ... 7. 0-0 ... 8. Nbd2
Themes: Solidify and fortify your king before you attack. h3 is an important move so ...
I found two sources. For fans of the USCF they have produced their US CHESS SCHOLASTIC BUGHOUSE RULES but not a grown up version that I can find.
The rather more serious Czech federation holds an annual bughouse championship in conjunction with their regular national championships as part of an annual chess festival. They publish their formal rules here.
Tempo is king in bug house for castling. By definition, unless your castle makes a immediate threat somehow, you have lost 1 tempo. In other words, it is at least one more move until you improve or gain position to attack.
If it takes your op 2 or more moves to make a threat, then you have a +1 tempo gain and it might be worth it.
If you are under immediate ...
In bughouse there are no formal rules, since bughouse isn't exactly a formal game :)
But from my experience, the two most common ways to deal with this are:
A player counts to 10 after moving, and his opponent has to move before he reaches 10.
You are only obligated to move once the person sitting diagonally from you (your opponent's partner) moves.
For an opening to be good in bughouse, it needs to incorporate both boards. Timing, material trades, attack/defend all have a huge influence. On top is predictability. If you know what the ops will try, then you may come up with a counter.
For example, 3 ... KxN is playable by black if there are limited material and a huge flood does not come on board. If ...
Yes, you take the same formula and do absolutely the same calculations. Elo formula has very little to do with chess (except of it is used to calculate rating in chess). You can take any event that has win/lose/draw and apply elo formula to calculate the rating.
In bughouse you play in a team of two, so you will end up with a rating for a team.
Sacrificing a piece on f7 (via Nf3-g5-f7 or e4, Bc4, Bxf7) creates a hole on f7 which can later be filled by a parachuting piece. This can be quite effective particularly if you have paratroopers ready from your partner's game.
https://www.youtube.com/channel/UCcKXwA_lo3Zpz3_Mc-WVLtw is the YouTube channel of Helmsknight. She is a strong player who plays with Nakamura, Seirawan, and many other high rated players. Interesting is that all these players tend to castle before starting an attack.
Just like normal chess, starting an attack on this (these) square(s) is often a good ...
Not having a governing body for bughouse, the rules are a little informal.
Per the Wikipedia article:
Depending on (local) rules threefold repetition applies, in which case
the reserve of pieces is not taken into account.
If you think about it, if the available pieces were taken into account, first, with no scoresheet, it would be really hard to prove,...
It is certainly believed by many that castling is a "bad" move in bughouse (and if king side castling is weak, queen side in my experience can be much worse). But I have seen world class (2500+) BH players castle either side, probably more commonly k-side.
One of the chief ways in which a castled king (on the king side) is attacked is via the H ...
Since there isn't much material out there to study, the best way is to play with better players. Of course, studying tactic problems is great for chess and the variants. FICS (free internet chess server) is probably where the best Siamese (bughouse) players are.
It helps if you have some opening systems worked out (since in Siamese being ahead on the clock ...
The way I've played it is an alternative. The rule is that you can't stall for more than three moves of your teammate (so if your teammate has made his third move since your last you must move before he can move again).
Of course this still isn't a good role for serious competition because you do need a kind of gentlemans agreement so that you don't have ...
Providing that teams are not fixed, Elo (and Glicko too) does not fit your needs, because it's designed for 1-on-1 matches only.
You need something that manages both team performance and players' rating, as TrueSkill or rankade, our free-to-use rating system. Here's a comparison between aforementioned ranking systems.
This reddit page has a ton of information, coming from a strong player.
Excerpts (z means "crazyhouse") :
The standard rules apply: develop your pieces, control the center, and get your king to safety. But there are some opening ideas uniquely emphasized in z:
Flank pawns should usually be kept where they stand in the opening. ...
according to engine, the italian game is good, and the best reply to the italian is 3...d6. In crazyhouse, avoiding the fried liver is important for players of all level cause crazyhouse give white big attacking chances!
Bughouse really doesn't. What can help you is shogi. Shogi is similar to chess but with complications that start almost immediately and become much more crazy than in chess. The reports that I have had from multiple players who went from chess, to shogi, back to chess is that the chess tactics suddenly seem exceedingly easy when you return.
To speculate for ...
In general, in a bughouse game, one of the players in the team attacks while the other team member defends. Thus, when the defender gets attacked, the attacker sacrifices a lot of material. This material goes to the other team member (attacker), who can the use the material to fuel their attack. Thus, the defender loses (or saves) the match. Defensive ...
FWIW, I am not a good bughouse player, but that may be more due to my poor blitz play.
It is better to be aggressive and attack in Bughouse, If you are attacking on both boards, you will likely win, and yet, both white and black have to be concerned with defense, as dropped pieces can start an attack out of thin air. The best defense is a good offense even ...
I think any strategy has to be based on the strengths and weaknesses of the players in a much more pronounced way than in the 2 person game.
Here is an example strategy where one player is a strong tactician and the other a strong positional player.
Generally speaking a piece in the hand is worth more than a developed piece particularly to a fine tactical ...
There is no pairing program which can do what you want. No program exists to change the partners every round according to the previous results. Pairing programs also try and avoid pairing players or teams which have played before.
Exactly how the partners would vary and how you would decide who had played whom is not clearly defined in your system. Your ...
In general it's a good idea, but to every rule there are exceptions. For example, if your opponent's king is safe (such as from castling) and he has lots of pieces around defending, sacrificing the knight on f7 may not be a good idea.
As the question you linked indicates there is a way to run bughouse engine games via FICS using XBoard/Winboard, which I also explained in my answer to a related question.
However, if all of your engines are anyway running locally, that is neither very convenient nor an efficient way of running such matches, since the server communication in principle is ...
Here is a rule that I think works:
Every piece you capture can be dropped by your partner only after his/her next move.
This prevents the situation you mentioned. Of course, it is still possible to reach a situation where each team has the turn at one board but does not want to move, but the specific problem you ask about would be mostly eliminated.
Well, since the values of pieces in bughouse chess depends severely on the position type (e.g. a queen is often useless) you may want to stall/not play immediately when you're waiting for a specific piece to complete your strategy in general, not necessarily to win you a piece or gain some specific advantage.
E.g. you may have noticed experienced bughouse ...
I don't think nf3 is bad at all but the multiple moves to sac on f7 is using up too many tempi and also giving up a knight is different than saccing a b. i think against any team over 1500 or so a team on which white plays this opening would lose pretty consistently. a tempo is a very valuable thing in standard chess and probably more valuable even in BH.
1. Nf3 is a bad move in bughouse. Nf3 intending to Ng5, Nxf7 is not good because this idea can be easily refuted.
1. Nf3 e6 2. Ng5 Qf6 3. Nxf7 Qxf7
Place the knight on g6, Qe7, pawn on f7, Kd8 and Black king is surprisingly safe.
There are many other good options for White such as 1. e4.
