FISCHERANDOM CHESS GENERATOR
  position #  random
FEN: brknnbqr/pppppppp/8/8/8/8/PPPPPPPP/BRKNNBQR 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!

Feb-15-18  morfishine: Standard setup is symmetrical. Chess960 setup is almost always asymmetrical (though the same pieces still must be opposite each other). However, it is possible with the random setup that the standard setup results! A minimum # of rules guide the 960 setup, for example, each side must have a DSB & LSB (ie: pure random setup could result in 2 LSB's or 2 DSB's).

Players are forced to rely on their talent and creativity (instead of rote memorization of opening lines)

  alexmagnus: <Players are forced to rely on their talent and creativity (instead of rote memorization of opening lines)>

If 960 becomes the standard, this "advantage" will quickly go away and players will memorize 960 theory. It's 960 times more? So what? Modern theory grew by more than that in the last century - think of it, in Nimzo'a times they could cause controversy by playing a novelty on move 3.

Also note that most games in MC vs Naka were not decided in the opening but in the endgame. The role of the opening is overrated by players and spectators alike

Feb-15-18  Monocle: <Absentee: <Monocle: <Absentee: The pieces are as uncoordinated as they are in the classical starting setup, the difference is that you're used to it.>

Since when is piece coordination determined by how familiar you are with the position?

Feb-15-18  morfishine: <alexmagnus> The standard setup is one of the 960 possible initial setups. Similar themes still exist between standard & 960, for example, controlling the center with pawns and smooth/quick development. Personally, I have a lot of fun playing Chess960
Feb-15-18  zanzibar: <drleper> Yes, it seems rather clear by the light of day that 960 needs XFEN or SFEN for castling under certain circumstances.

But regular FEN can be used to truncate any 960 game's movelist beginning, as I said last night. The assumption is that all the subsequent moves are legal. It's not a big issue, and doesn't have much functionality, so no need to belabor it.

For people wondering about the difference between S-FEN/X-FEN/FEN castling rights - I think this page is useful:

https://www.chess.com/clubs/forum/v...

Anyways, thanks for setting me straight on the issue.

Feb-16-18  drleper: <zanzibar> Seems like a misunderstanding, no worries. There doesn't appear to be much discussion about S-FEN online for some reason, but I only have experience with ChessX which is using X-FEN.

  Joshka: To really mix things up, why not have players play with different positions, and have them pulled at random!! Say Player A will be using position 49, Player B will be using 251!! Also, they only get to know the starting position one minute before game time!!!
Feb-16-18  Spectator123: ... and let them play blindfolded, also when shown starting position! :-)

  beenthere240: How about they play blindfolded WITHOUT being shown the starting position? The arbiter would tell them if a check had occurred, a piece had been taken, or if a move was illegal.
Feb-16-18  alfamikewhiskey: Of the possible positions, RKNNBBRQ is the "oddest" imo.

  casaschi: @chessgames.com contrary to the earlier statement in this forum, pgn4web supports chess960 as you can see in this demo: http://pgn4web.casaschi.net/chess96...
Feb-18-18  savagerules: In Game 11 of Naka-Carlsen the first move was 1. 0-0 0-0. Both castled on the first move! At any rate I think this match was more interesting than a bunch of Berlins or Guioco Pianos or something.

Feb-19-18  Marmot PFL: Thought the idea of 960 was to put the players on their own to the maximum so letting them prepare before the game with computers kind of defeats the purpose.
Feb-19-18  morfishine: <Marmot PFL> UR correct, Chess960 forces the players to rely on intuition instead of ream after ream of opening data

Thats the fun of it

  chancho: <I think the Fischer Random (or Chess960) match against Hikaru Nakamura (who won the last Mainz unofficial World Championship back in 2009), held at the Henie Onstad art gallery in my former home-municipality Baerum, was a great success and well beyond what I had expected.

The games, where a new piece set-up was randomly generated among the 960 possibilities for every second game to allow one white and one black each before moving to a new set-up, turned out to be rich in chess content, highly interesting and surprisingly taxing compared to classical chess by posing new and demanding challenges from move 1.

The match was hard fought, and while it took us some time to learn to absorb new structures, and both continued to be tempted to transform the positions into known classical structures throughout, especially the third and fourth day revealed such non-classical piece placement that we were consistently forced to enter pristine positional structures.

I hope there will be more such events in the future also at top level. Still, it will be a relief to return to classical chess in my next event in April.

Maybe some of the ideas seen and pursued in this match will serve as inspiration for me also in classical chess.

We played four days of slow rapidchess (each player having 45 minutes for 40 moves plus 15 minutes for the rest of the game) and 8 fast rapid-games on day 5 with 10 minutes + 5 seconds increment per move.

Starting with three hard-fought draws on day 1 and 2, the next 5 games were decided. I played quite well in game 4 and despite his stubborn defense I managed to win in the end.

He simply didnít have time to find all the only-moves in the tricky queen ending.

Nakamura as expected tried to complicate and avoid quiet positional struggles and sometimes accepted being worse out of the opening.

His clever defense and tenacious resourcefulness kept him in the match.

I could have taken a clear lead after four days but didnít claim a draw in time with rook and bishop against his rook in game 8.

Frustrated after squandering a won position, I lost my head, as could probably be seen by the higher pulse Ė we had heart rate monitors which I think is a great idea Ė and the unreal time loss was my involuntary additional contribution to chess as performance art taking place in the Dag Alving photo-art exhibition, partly about chess history, surrounding the match.

I had a 9-7 lead and was able to forget bygones and focus on having fun the last day.

Managing to hold the queen versus rook and pawn ending in game three yesterday was psychologically important, maybe even decisive. I won game four, and was happy to secure match victory by winning game 5 as well.

Iím not sure Iíve played more than 5 rapid games in one day before.

The energy level dropped dramatically, and we even started to make serious mistakes in well-known structures and endings.

I won 14-10 in the end and that is a decent result. Non the less, I think both of us could play better, and I already look forward to new Chess960 challenges in the not too far future.

The match was covered live by main channel NRK, and Iíd like to thank everyone involved for the great event!!

I don't consider it to be "Chess". But then, I also consider online chess to be a variant.

  Dionysius1: What about generating a random chess starting position but changing the object of the game to returning the pieces (excl pawns) to the classical positions? One could use advancing the pawns to create a protective barrier to make captures difficult, in which case the game ends.

  cro777: The World Fischer Random Championship is now officially reconized by the International Chess Federation (FIDE), the governing body of international chess competition.

Prior to 2019 FIDE did not recognize a Fischer Random world champion or sponsor regular tournaments in the format. But this year FIDE has granted the rights to host the inaugural FIDE World Fischer Random Chess Championship cycle to Dund AS (which organized the 2018 unofficial Fischer Random world title match between Classical chess champion Magnus Carlsen and recognized Fischer Random ace Hikaru Nakamura), in partnership with Chess.com.

The WFRCC Cycle is a biennial event, and consists of the online qualification and physical final play. (For the first time in history, a chess world championship cycle will combine an online, open qualifier and worldwide participation with physical finals).

Arkady Dvorkovich (FIDE president): "It is an unprecedented move that the International Chess Federation recognizes a new variety of chess, so this was a decision that required to be carefully thought out. But we believe that Fischer Random is a positive innovation: It injects new energies an enthusiasm into our game, but at the same time it doesn't mean a rupture with our classical chess and its tradition. It is probably for this reason that Fischer Random chess has won the favor of the chess community, including the top players and the world champion himself. FIDE couldn't be oblivious to that: It was time to embrace and incorporate this modality of chess."

  cro777: FIDE World Fischer Random Chess Championship 2019.

Massive open online qualifiers have been completed and we have six players emerging victorious:

Wesley So, Ian Nepomniachtchi, Peter Svidler, Vidit Gujarati, Vladimir Fedoseev and Iranian prodigy and speedster Alireza Firouzja.

https://www.frchess.com/news

In order to integrate classical and Fischer Random histories, three players will be joining them: Fabiano Caruana and Hikaru Nakamura (in the quarterfinals) and Magnus Carlsen in the semifinals.

The online quarterfinals begin October 4. The venue for the semifinals and final will be Norway's Henie Onstad Art Center, located just outside Oslo, which hosted the remarkably successful pilot event, the unofficial title match between Hikaru Nakamura and Magnus Carlsen in 2018. As mentioned earlier, for the first time in history a chess world championship cycle is combining an online, open qualifier and worldwide participation with physical finals.
