  Variants


There are several variants of this game, all are different from the now played and said traditional chess.
Some of them are played on different sized boards, some of them on non-quadratic boards, there are some variants which are played with different pieces, and of course always with different rules.

Actually the Fischer Random (Fischerandom, FR, FRC, Chess960, C960) variant is supported in the club.

Bobby Fischer (Robert J. Fischer) the earlier chess world champion worked out this variant in 1996.
It's played on the same board with the same pieces as the traditional chess, only the order of the pieces is different.
Pawns are located on the 2nd and 7th rank, pieces on the base rank as well, but their order is different, random. It's not sure, that the rooks occupy the corners of the boards, it's possible that other pieces will take place their.
It's sure that both players have bishops on different colors, and the kings are located between the rooks (so they can castle). Ensuring the same chances black starts with the mirrored setup.
The learned opening rows, variations are less important here, because the pieces are on different squares, and there are 960 different initial setups.

Fans of the Fischer Random chess say, here creativity and talent is more important than memorization and analysis of opening moves.

If you believe or not it's up to you, the chance is given, you can play server based correspondence Fischer Random chess games in the E4EC.
The next pictures show all the 960 different initial positions of the FRC variant.
You can see the white pieces only, pawns don't change, and black has the mirrored setup.

Positions 80 - 159
Positions 160 - 239
Positions 240 - 319

There are many very good articles and rule translations on the web, you can start e.g. here if you want: http://en.wikipedia.org/wiki/Fischer_Random_Chess.

Nevertheless this chess variant is a widely accepted one. The first world champion is the Hungarian Peter Leko from 2001.

ELO Rating

Muscler An ELO rating is the result of statistical calculations designed to measure the playing strength of players. These methods were developed by Arpad Elo and are named after him. The ELO system is in almost universal use and has been further refined by others, notably Glicko, but is still named after its creator.

In devising the ELO scale, some premises were used that are worthy of note. It was decided that a rating of 2000 would be the equivalent to scoring 50% in a US Open Championship. It was also decided that a player's rating would never be negative.

Importantly, the standard deviation was fixed at 200 points. This means that if a player's true strength is 1500, he will score around 68% of his results within the range of 1400 to 1600 (as measured by performance formulae). Another result of fixing the standard deviation at 200 points is that it also defines playing categories. For example, most International Masters and Grandmasters are in the 2400 - 2600 category, most national masters in the 2200 - 2400 category. Those in the 2000 - 2200 category are called Experts, or Candidate Masters.
