FISCHERANDOM CHESS GENERATOR
  position #  random
FEN: brkbnrqn/pppppppp/8/8/8/8/PPPPPPPP/BRKBNRQN w KQkq -

How to Use This Page
  • This page is used for generating a random position to play Fischerandom Chess. Every time you reload this page, or press the new position button, a different position will appear. Just set up a chessboard based on the diagram above, find an opponent, and have fun.

Quick Rules for Fischerandom Chess

  1. Fischerandom Chess is played with a normal chess board and pieces. All rules of Orthodox Chess apply except as otherwise noted.
  2. The initial configuration of the chess pieces is determined randomly for White, and the black pieces are placed equal and opposite the white pieces. The piece placement is subject to the constraints:
    1. the king is placed somewhere between the two rooks, and
    2. the bishops are on opposite colors.
    3. pawns are placed on each player's second rank as in Orthodox Chess.
    There are 960 such configurations.
  3. Castling, as in Orthodox chess, is an exceptional move involving both the King and Rook. Castling is a valid move under these circumstances:
    1. Neither King nor Rook has moved.
    2. The King is not in check before or after castling.
    3. All squares between the castling King's initial and final squares (including the final square), and all of the squares between the castling Rook's initial and final squares (including the final square), must be vacant except for the King and Rook.
    4. No square through which the King moves is under enemy attack.
    The movement of the King and Rook during castling should be easily understood by players of Orthodox Chess:
    1. When castling on the h-side (White's right side), the King ends on g1 (g8), and the rook on f1 (f8), just like the O-O move in Orthodox chess.
    2. When castling on the a-side (White's left side), the King ends on c1 (c8), and the rook on d1 (d8), just like the O-O-O move in Orthodox chess.
    3. Sometimes the King will not need to move; sometimes the Rook will not need to move. That's OK.
  4. The object is to checkmate the opponent's King. Have fun!

Apr-06-14  Bob Loblaw: Here's an excellent video demonstrating the moves in Aarima (with some hot jazz in the accompanying audio track). http://www.youtube.com/watch?v=Tjwi...
Apr-07-14  morfishine: I have a blast playing Chess960 over at <ChessCube>. The fun never ends!
Apr-07-14  JustAFish: I like Fischer Random, I'm pretty sure that it will never replace the traditional setup- not because computers will play it out, but precisely because traditional chess has so much theory.

The way I see it, chess- that is, traditional chess- is not one game, but an entire ECO volume of different games. This is a cultural legacy that has been built up over the centuries.

When two players sit down, they mutually perform a dance and end up "deciding" to play a game called "Sicilian Moscow", "Ruy Lopez- Marshall Gambit," "St George Opening" or "VanGreet" or whatever... Each of these games has a different flavor and and progresses along different lines.

Part of the "dance" of a chess game is the skill of steering the game into these "sub-games" that a player knows how to play well.

Throwing 960 into the mix dumps all of this "culture".

Apr-07-14  randomguy181: nit picking?? the point I'm trying to make is that if you are going to call something random then let it be completely random. If it turns out that both sides have 2 light or dark squared bishops then so be it
Apr-07-14  SirRuthless: Its not called "random." It's called "Fischer random." The point of the game is to remove opening memorization as an advantage and prevent the solving of the game from the front end. The fun of FR is that as you move into the middlegame the game becomes just like the chess you know. There is no reason to mess with the bishop color distribution. Even if chess gets solved, 960 wont be for a while longer and even if it is, no one is going to remember the best strategy for every opening configuration, especially if it is a much shorter time control than classical.

  Sneaky: <randomguy181> You're welcome to make a new variation of chess adhering to your ideas, allowing for two bishops on the same color or the king that's not between the rooks. I'm skeptical it will be much fun, but nobody's stopping you from giving it a try.

Bobby explicitly explained in his radio interviews that Fischerandom was intended to preserve the spirit of the game of the chess. That means that we always have one bishop of each color, and that castling is, to some degree, a move that gets the king out of the middle and help connect the rooks. Without those basics principles preserved, the game would scarcely resemble the chess we all love.

  Sneaky: <Throwing 960 into the mix dumps all of this "culture".> ... <I completely agree.> I agree as well.

But there are some who think abandoning this culture is a good thing, and they have a point as well. In any case it's nice that we now have a way to temporarily abandon that culture, just for the fun of it.

  Penguincw: 2 random questions I have about Chess960.

The first one has to do with castling rules. In standard chess, when castling takes place, the king can not be in check, castle through check or into check (along with other rules). However, for Chess960, is it possible for the rook to land in "check".

For example, take the following position:

For example, if the game opens with 1.e4 b6 2.Qd3 Ba6 3.Qg3 h6, is 4.0-0 here legal? I'm not saying it's a good move, but I'm asking if it's legal.

After 3...h6

Also, with this generator, is it possible to go from FEN to position number? Thanks. :)

Nov-05-14  FairyPromotion: <Penguincw> The position you gave is a transcendental chess position, and not a 960 one, since the starting position of pieces do not mirror each other. I'll assume you meant the white rook to be on on a1 and the bishop on c1, mirroring blacks position, while the black queen is on f1, and the king is on g1, mirroring whites position. Otherwise your variation doesn't work.

Now to answer your question, to my understanding the castling on the position after 1.e4 b6 2.Qd3 Ba6 3.Qg3 h6 is legal, as the king does not pass through the attacked f1 square. The rooks movement is irrelevant AFAIK, just like in regular chess. *

*- Ok, as I was typing that I remembered that my GUI <Arena 3.0> has the Chess 960 option. I played the line, and it allows castling in that position. :-)

As for your second question, I don't think that's possible with this generator, nor there is a standardized numbering for starting positions in Fischerrandom. Here the position you gave is #27, while in my GUI it's #437.

Hope this was helpful! :-)

Yes. When I saw the position given on the board, I just changed a couple of white pieces, without changing any black pieces. :)

< Hope this was helpful! :-) >

Yes it was. Thank you very much. :)

  zanzibar: I just popped over here after reading Daniel's post on threading, I didn't even know this forum existed.

<perfidious: Having one's bishops on the same colour seems a mite silly.>

Just for the record, since no one else commented, FischerRandom requires the bishop's to be on opposite colors.

(I don't play it, well hardly ever, but I remembered that about it, and double-checked wiki.)

Mar-11-16  chess959: We now know that some people intentionally misdescribe chess960 as a chess variant. What could be the main reason for this?

And if the purists are so insistent that chess 960 is not “real chess”, why did we let computers rule the analysis of classic chess (SP518)? When did that become acceptable?

Mar-27-16  SetNoEscapeOn: <chess959: We now know that some people intentionally misdescribe chess960 as a chess variant. What could be the main reason for this?>

If a game doesn't have the exact same rules as classical chess, it is considered a variant. This is merely a definition, not a condemnation.

  RookFile: What I would like to see is, each side could set up his men, except the pawns, any way he wanted to, but had no knowledge of how his opponent was doing the same until the game started. It seems to me this is closest to how real armies prepare for battle.
Oct-30-16  Sissafischkasp: I'm just new to "Fischer's Random Chess." I found it interesting, mathematically. Ordinary chess position 5,362 possible chess positions or 8,902 after two ply moves each. 71,852 different possible chess positions, or 197,742 total positions in just four moves. After five moves there arises 809,896 different positions. What about six and seven moves? Ad infinitum, really. And "Fischer's Chess Random?" Mathematically, how many possible positions will there be in first five move of both white and black color?

  Jambow: I enjoy playing 960, Fischer Random or what ever it is called, and seemed to do better than at classical chess relatively speaking.

  flimflam48: I have a horrible feeling that computers are effectively wrecking chess...since any position can be analysed to the 'nth' degree...and being human, we tend to go with the computer's analysis nearly all of the time instead of going with our own 'gut' feeling...this may happen to chess 960 as well as classical chess.
May-13-17  BlindBlunder: Full support to RookFile. Moreover, that idea may be generalized: https://www.chess.com/forum/view/ch...
May-14-17  morfishine: I like <RookFile>'s idea too, almost as much as I like Chess960.

Whats funny is how some people question if Chess960 can even be called "chess"

Of course it can

Here's a News Flash for you: The current game of chess, lets call it "standard chess", is WAY different than the original format; so any offshoot is of course "chess" or another form of "chess"

  paulalbert: I was not aware of the recording of Bobby explaining Fischer Random chess above. It is certainly a simple, articulate explanation. As he says, learning the rules is easy. Actually I have never played Fischer Random. After 65 years, I am still trying to play the conventional set up with more expertise than I have currently, but at 74 years of age ( same as Bobby would have been ) I am running out of time.
