# Tourneys management

The tourney is clearly the primary element of the whole system, everything has been designed to allow an easy and fast management of these events.

The tourneys window by default does not show future tournaments: to see them, reset the filter applied to the date field.

## Menu actions

In addition to the standard actions the menu at the top contains the following items:

Tourneys management

Details
  Opens the management window of the selected tourney.
Competitors
  Opens the Competitors fixup window that allows the correction of the competitors of old tourneys.
Replay again
  Allows duplicating an existing tourney, expecially handy on teams events: it basically clones a tourney on the current date, with all its competitors; just be sure to update the description, maybe adjusting the date of the event!
Download
  Downloads an archive of the selected tourney’s data.

## Insert and edit

Each tourney has a date and a description of the event and there cannot be two dictinct tourneys in the same date associated to a single championship.

The location is optional.

The duration and prealarm refer to the length of a single round, and are expressed in minutes. They will be used by the The alarm clock window. window.

A tourney may use a particular rating: in such a case, the first round is generated accordingly with the rate of each player instead of using a random order.

The pairing method determines how the pairing are done at each new round:

`Ranking order`
  the `serial` algorithm will try to pair a player with one of the players that follows him in the current ranking order, for example the first with the second, the third with the fourth, and so on;
`Cross ranking order`
  to delay as much as possible most exciting matches, the `dazed` method is more elaborated: it takes the players with same points as the pivot, and tries to pair the first with the one in the middle of that series, the second with the middle+1 one, and so on.

The delay top players pairing, meaningful only when the tourney is associated with a rating, determines how many rounds will use an higher priority for the Glicko rate of each competitor over the net score in the ordering used by the pairing method.

Note

SoL uses five parameters to rank the competitors:

1. points
2. bucholz
3. net score
4. total score
5. Glicko rate

Before playing the first round the first 4 values are all zero, so only the fifth is crucial. At the beginning of the second round, all winners have the same score and the same bucholz, thus the net score become decisive.

From the point of view of rounds generation, for the beauty of the game it is generally desirable to delay as much as possible the matches between top players: to this end it is sufficient to give an higher priority to the Glicko rate, moving it to the third place, after the bucholz and before the net score.

The value assigned to this field controls how many turns shall be generated using this different sorting criteria: the default value of `1` means that it will be used at the end of the first round to generate the second one; a value of `0` instead inhibits this delay and therefore only the first round is determined by the Glicko rate, from the second onward it becomes irrelevant. Values higher than `1` have an impact less and less significant, because from the third round on the points and the bucholz become more and more predominant.

The phantom score is the score assigned to a player in the matches against the phantom player, when there are an odd number of competitors. By convention these matches assign a score of 25 to the player but there may be cases where a different score is more appropriate, for example when the number of competitors is very low and winning 25—0 would be an unfair advantage.

The responsible is usually the user that inserted that particular tournament: the information related to the tournament are changeable only by him (and also by the administrator of the system).

The finals is the number of finals that will be played. It can be either left blank or it must be a number between `0` and `2` inclusive: in the former case, finals will be handled manually, that is SoL won’t generate final matches but the results shall be reflected by adjusting the final prizes. A value of `0` means that there won’t be any final, `1` means that SoL will generate one single final match for the first and the second place, with `2` SoL will generate two final matches, one for the first and second place and another for the third and fourth place.

The final kind determine the kind of finals that will be played:

`Single match`
  the `single` kind will create one single round, with a match between the first and the second ranked competitors and, if finals is set to `2`, another one pairing the third and the fourth ranked competitors
`Best of three matches`
  the `bestof3` method will create at most three rounds, the final is won by the competitor that wins at least two of them.

As soon as the final scores of all these rounds are entered the prize giving operation to assign final prizes is performed automatically.
