Time Controls

Players can use more different time controls in the club.
10/30 - This is the default time control. Club level tournaments and games by pairing use this one. Here 10 moves must be taken in 30 days. Clocks start with 30 days, the thinking time is always subtracted from them, but another 30 days are added at every 10th move. The maximum the clocks can show is 40 days.
10/40 - This is a bit slower time control. 10 moves must be taken in 40 days, the addition is 40 days, and the maximum is 50 days.
10/50 - More slower, 50 days for 10 moves, 50 days addition at every 10th move, the maximum is 65 days.
5+1 - This is a faster one. Here the clocks start with 5 days on them. The used up thinking time is subtracted also, and 1 day is added at each move. The maximum is 30 days here too.
The server manages the clocks, it calculates the thinking times, adds, subtracts, and does everything. Records everything in the game logs.
If a clock runs out of time, the player will be considered as being on an unannounced vacation. If it elapses also, he'll loose the game, the opponent can claim result.

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.
