Chess960 Explained!

  • 7 years ago · Quote · #1


    What is Chess960?

    Chess960 (also called FischerRandom) is just like regular chess... except that the starting position is shuffled to include 960 different possible positions! So you can throw out your opening book, but keep your opening principles. You play the same, but you just have different placement of pieces on the starting row.

    The only change in rules is that castling is funky - when you castle, the king/rook end up in the same position as when they castle in regular chess (king on g-file and rook on f-file for kingside, king on c-file and rook on d-file for queenside).

    The 960 comes from the number of different possible starting positions where there is a rook on each side of the king and where there are bishops of opposite color.

    To start a 960 game, go here: and under Advanced Options choose Type: Chess960. Or, find a game here:  ->

    I was playing my first game in chess 960 and after my opponent made his 15th move a second king magically appeared on my back rank.  I couldn't move it but I couldn't move any pieces onto that square.

    Question -- just started a game. Inside the game (on the playing screen) my opponent and I are both listed as 1200, as we are both virgins to Chess960 that is good. Seems as if our ratings will be kept distinct from our Online games.... but... the game is still listed on my Online Games page and on that page my opponent and I show our same online chess ratings.

    So... how do ratings work for Chess960? Are they kept separate or not, from Online?

    Will there be 960 Team Matches and Vote Chess eventually do you think? I see there are already tournaments going... but for the groups, it'd be interesteing. I just tried to see if I could set something up for one of the groups I admin and not yet possible.

    Hi guys,

    This is a great variation on standard chess.  You will like it, I do.  There are otb tournaments and a world champion for this variation.  Years ago, I played a variation of this variation which was called transactional chess.  In that game both back ranks were scambled differently from each other.  That meant that games had to be played as doublets against each opponent.  Both players played one game as white and one game as black.  That was a blast!

    Watch your backrank.

    Can you tell me which of your teams set up the match? I'd like to message your team Admin and ask how s/he set it up.

     Of course it is, but this makes you think about your opening moves. Very tactical.

    I think it's nice for a change. The only annoying thing can be to get your bishops developed. 

    Yes, after only playing part of two games, I can see that is problematic. I also gather that all of the old rules (avoid knights on the rim, don't bring Queen out early, castle a.s.a.p., etc) may not necessarily hold the same weight as in standard chess. Already I have seen (mostly in my opponent's stronger play, not only in my own) that an early Queen development, for instance, can be beneficial, especially as it can help tie down your opponent's pieces (bishops esp) to their back rank... and depending on where the knights are at the initial set up, developing a knight on the rim may well be the right move.... I'm finding the interplay between following all the old rules of thumb and needing to be creative and open very entertaining!

    I'm finding gaining (or losing) tempos key in the opening as are the threats of spoiling castling. I have I think four games on the go. I'm really enjoying them. :)
