Players can enter tournaments organized by the club. To protect serious
players, new members cannot enter tournaments immediately after their
rated games need to be
finished to be considered as a serious player and to be able to enter
tournaments. Normally finished games are those that end in checkmate,
stalemate, a draw agreement, a valid draw claim, or resignation. Friendly, deleted and
time forfeited games don't
count into this value.
When a player enters for a tournament, those of their games which
belong to already entered players are started. Their other games in
that tournament are waiting until the corresponding player enters.
When a tournament fills up, another tournament is started automatically
with the same parameters. This ensures that in each rating class, in
each (future) types there is always a tournament which is open for
Players can enter for more tournaments until they have enough free game
slots. This is 16 initially and raises by 2 with each normally finished
games until 100.
Players can play other games simultaneously that are started by
challenges or pairing, until
the above criteria are met.
Each won game is worth 1 point, a draw 0.5, a lost 0. The winner of a
tournament is the player who collects the most points. In the case of a
tie, the Sonneborg-Berger formula decides the winner. When the last
game finishes in a tournament, the entrants get result announcement and
the tournament closes.
All tournaments are time controlled.
Now all of them run in 10/30, so 10 moves must be taken in 30 days. The
ceiling is 40 days. This means all their games run in that time
control. Later another tournaments may come with either faster (e.g.
5+1) or slower (e.g. 10/50) time controls. External organizations'
tournaments can run under different time control.
The vacation policy applies
to tournament games. Players can announce their planned vacations, or
when they are in trouble, the automatic vacation protects their games
Currently, the following types of tournaments run:
Ratings are recalculated after each finished game immediately by the chess server. This is the standard
elo rating calculation implemented by the Glicko
method. Except those games where the club's Regulations don't apply. These game are
not rated by the club.
- Class based 7 player single round-robin: These tournaments are class based, this ensures that players can play others around the same rating. These classes are shown in the table on the right. In this tournament 7 players play one game with each other entrants in alternating color. This means the maximum number of simultaneous games is 6 for one player.
- Multiclass 9 player single round-robin: Players of three neighbor classes can enter for the same tournamets. This ensures, players can play others with higher rating difference.
Multiclass 6 player double round-robin, Fischer Random: Three neighbor classes belong to these tournaments, but here all players play two games with each opponent, once as black, once as right. The games run under the rules of the Fischer Random variant. A tournament like this means 10 simultaneous games for each entrants.
Invitation based 15 player single round-robin: This is almost the same as above, external organizations use this type with 15 entrants. Players according to their previous results are allowed to enter for these tournaments.
There is no prize in club level tournaments, but they give good play
opportunity and appreciation for the winners.
About 800 years after the birth of Christ, chess was well known in the Arabic World. Al-Adli was the greatest known player of that age until 847. He was the closest friend of the caliph, a poet, and a minister-like official.
The game was a bit different than the modern chess we know. The initial setup was the same, as well as the king, the knight and the rook. The queen was the weakest piece because it could move one square and in diagonals only. Bishop moved in diagonals, but only two sqares, and could jump over pieces, didn't attack and didn't defend the nearest four squares. Pawns could move one step only and there was neider castling.
The server calculates a reliability factor for each player according to their actions in the past few weeks.
This value is influenced by many different things, for example if their settings are correct, if they had a timeout in a game, or if they have unannounced vacations, etc.
The value is always between 0 and 10.
New players start at 3.5.
After they set up their basic settings such as the country code, gender, real name, birth year, this value goes up to 5.
If they successfully start few games and also finish them in order, without timeouts, silent vacation, the value raises around 6.
As they finish more games, and as the time goes without any problem with them, the value still raises.
Players with many months of membership and with a lot of games and without any problems can go over 9.
This may help players to find the right opponents, and may give them an approximate view about their future opponents, without personally knowing them.
Protecting serious club members, players with too low reliability (less than 5) can't enter for new tournaments.
