# Rules for the ACP Women Series 2015

**I. Purpose**

The ACP Women Series (ACP WS) is a tournament circuit organized by the ACP (Association of Chess Professionals), which regroups the most important tournaments in the world where women take part during a one-year chess season. Players taking part in these events gain points according to a ranking system devised by the ACP. Special prizes will be awarded to the best players, once the season is over (see point V.) .

**II. Dates**

The 5th ACP WS take place from January 1st until December 31th 2015. A tournament is eligible for the 7th ACP WS if the date of its first round is included in this time span.

**III. Concept**

- Events played at both classical and rapid time-controls will be counted, albeit with an inferior coefficient for rapid events compared to classical ones. Classical events are those where a player has at least 90 minutes (regardless of possible time increments) to complete the game. Rapid events are those where a player has at least 15 minutes (regardless of possible time increments) to complete the game. Blitz tournaments will not be part of the ACP WS.

- A complete list of tournaments included in the ACP WS will be published on the ACP website (www.chessprofessionals.org) and updated as the season unfolds.

- Updated players’ rankings will be published on the ACP website (www.chessprofessionals.org) and shall appear within a week after one of the ACP Tournaments is over.

**IV. Events**

Events counted in the ACP WS can be of the following formats:

A.Individual women tournaments

B.Individual mixed tournaments

C.Team competitions

**A. Individual women tournaments**

- Individual women events counted in the ACP WS can be held according to the following formats: round-robin tournaments (RR), Swiss systems (Opens) and knock-out tournaments (KO).

- Individual tournaments of the ACP WS fall into 6 different levels according to their strength (R).
Level R 1) F 2375-2400 2) E 2400-2425 3) D 2426-2450 4) C 2451-2475 5) B 2476-2500 6) A 2500 and over **R**is determined as follows:**For RR tournaments****R = Ra**where Ra = average Elo rating of all participants;

**For Open and WS tournaments****R = (3xR1+2xR2+R3) / 6 + 45**if the total number of players in the tournament is 90 or more

where R1 - average Elo rating of top 10 players in the starting list,

R2 - average Elo rating of the next 10 players, from 11 to 20, in the starting list,

R3 - average Elo rating of the next 10 players, from 21 to 30, in the starting list;

and

**R = (3xR1+2xR2+R3) / 6 + N/2**if the total number of players in the tournament is under 90

where R1 - average Elo rating of top 1/9 part of all players in the starting list,

R2 - average Elo rating of the next 1/9 part of all players in the starting list,

R3 - average Elo rating of the next 1/9 part of all players in the starting list,

N – total number of players.

**For KO tournaments****R = R ¾**where R ¾ - average Elo rating of top ¾ of total number of players.

In case some or all participants of a KO tournament have qualified from an open, the following criteria have to be taken into consideration: the level of the qualifying open (determined as described above) will prevail if it turns out to be higher than the level of the final KO tournament.

- Within one level, ACP points are distributed using different coefficients, according to the type of tournament and the number of rounds. For the detailed tables of the ACP WS Points System for individual tournaments, see Annex 1.

- Any stage of any closed individual national cup or championship cycle (classic or rapid), whose strength ( R ) is less than 2376 but more than 2300 according to the ACP Points System, will be granted level Fn and counted with a coefficient 0,5 assuming that level F has coefficient 1. If R is less than 2300 the event will not be counted.

- Open tournaments played with less than seven rounds will not be taken into account.

- The ACP Board reserves itself the right to refuse counting a tournament, in case the results appear particularly suspicious. This will avoid pre-arranged tournaments influencing the final players’ rankings.

- In the event of circumstances unforeseen in paragraph IV, the ACP Board shall decide on the matter at hand. Decisions from the ACP Board are final.

**B. Individual mixed tournaments**

- ACP points will be awarded according to the rating (Elo) performance and the place taken in a tournament. Tables of the ACP WS Points System for individual mixed tournaments can be found in Annex 2.

- Women players will be able to gather ACP points only in tournaments which are part of the ACP Tour. The list of these events can be found at www.chessprofessionals.org . Other events will not be considered for the ACP WS.

**C. Team competitions**

- Several very strong team events will be taken into account. These can include international and national competitions.

- Only individual performances are taken into account; the results of teams are irrelevant.

- For her performance to be rated in the ACP WS, a player must have played at least 5 games in a certain event.

- ACP points will be awarded according to the rating (Elo) performance. Tables of the ACP WS Points System for team competitions can be found in Annex 3.

**V. End of season**

- A player has to be an ACP member for 2012 in order to have her results counted in the ACP WS. The deadline for membership renewal will be announced by the ACP Board in due time.

- The best eight players at the end of the season will be awarded money prizes. However, if the ACP succeeds in finding special sponsors, a Final Tournament will be organized. Money prizes would, then, be awarded according to the results of this Final Event.

- In case of tie for the money prizes or the qualifying places, the following tie-break system will be applied:
- The player who obtained her ACP points in the least number of tournaments will finish ahead.

- If the number of tournaments taken into account is equal for several players, the player who finishes ahead is the one who scored the largest number of points, once the worst tournament of each player is withdrawn from the calculation; if it is not enough to make a difference, the next worst result is withdrawn, etc.

- If point “a” and “b” don’t break the tie, a drawing of lots will have to take place.

- The player who obtained her ACP points in the least number of tournaments will finish ahead.
