Tournaments
Players can enter tournaments organized by the club. To protect serious
players, new members cannot enter tournaments immediately after their
registration. 5
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
entrants.
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
from timeout.
Currently, the following types of tournaments run:
- 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.
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.
There is no prize in club level tournaments, but they give good play
opportunity and appreciation for the winners.

ELO Rating
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.

Strict mode
Saying the truth, mis-writing a move in correspondence chess can be fatal for the game.
But it depends, if the miswritten move is still valid or not fully valid. For example if the check mark (+) is missing, our opponent can reject the move, and can send it back to us for correction.
But if we have two knights, one can move to e4 and the other one can move to e5, mis-writing 12.Ne4 to 12.Ne5 can be fatal, and there is no way to proof we wanted to move the other knight.
This is a problem, that can be solved in server based correspondence chess, that this club offers.
By default the server is very indulgent in accepting moves, it accepts invalid moves if they are still unambiguous, adds check and capture marks, doesn't require the move number, etc. This is for reducing the number of rejected moves, but it results that some miswritten moves are not rejected, and are accepted as a different move.
Those players who manually compose their move messages, and therefore sometimes miswrite their moves may find the StrictMode setting useful.
If they turn it on, the server will accept only fully valid, complete moves exactly as shown in the next example:
Move 1234 12.Nd2-e4
In strict mode the server requires the move number, one dot as white and three dots as black, the piece letter (even at pawns), the from square, the capture mark or hyphen, the target square, and the check mark if needed. If any of these parts is missing, or the whole move is invalid the server rejects the move.
This way the chance that a miswritten move can be valid as an other move is lowered quite dramatically.
