Although Vega has been designed to be very intuitive and easy to use it is recommended that the user reads this manual and tries to simulate a few tournaments in order to learn all of its functions The user must have some knowledge of the rules of the Swiss system and its implementation in Vega in order to properly manage pairing There are occasions when manual pairing is required The Vega web site contains a screencast demonstrating specific tasks 1 1 Document Conventions Graphical labels referred to in the text are marked using bold text Transition during menu navigation is marked using an arrow File Exit Parameters to be substituted by the user are marked with lt angled brackets gt 1 2 System Reguirements Vega runs on Linux and Windows operating systems from Windows XP onwards fitted with a hard disk and a graphic card capable of supporting a resolution of 800x600 A printer is recommended for the display of pairings and results during tournaments although in principle Vega could be used without it Vega will print only ASCII files HTML output can be printed from the browser but there is little control over page breaks Vega may run even on a USB pen drive 1 3 Installation Windows version Vega comes in the self extracting archive VegaSetup exe To install the program just double click on the icon program and follow the instructions Please do not install the program in the folders Desktop or Documents

9. Although this adjustment introduces some asymmetry between the front and the back cycle it avoids the streak of three consecutive whites or blacks Still the 1 plays four times with black in a five round span conversely N 1 plays four times with white Rotating tables If we exclude the first round each player plays once with white and once with black every two rounds It is the first round that complicates matters and makes somebody start the first two rounds with the same color Also it creates problems in double round Round Robin as shown above The idea is to move the first round in the middle of the round robin Or more precisely in the middle of pairs of rounds lt 2K 2K 1 gt For instance let s look at our 10 round example after excluding round 1 we have 4 pairs of rounds 2 3 4 5 The following Appendix relies heavily on a document authored by FIDE Arbiter Roberto Ricca 3 FIDE handbook C 06 Annex 1 Berger Tables for Round Robin Tournaments For a double round tournament it is recommended to reverse the order of the last two rounds of the first cycle This is to avoid three consecutive games with the same colour 46 6 7 and 8 9 We could move round 1 exactly in the middle And in order not to break the original Berger tables we just rotate it In other words we start with the original round 6 then 7 then 8 then 9 now round 1 and then round 2 round 3 round 4 round 5 Let s call it a Rotate 6

Each of the floaters is paired with the player having the highest R if possible having the opposite due color If there are more than one player with equal R the player with the lowest ARO is chosen 9 Final remarks The list of AROs should be published after each round to make it possible for the players to calculate the pairings on their own A situation which cannot be directly resolved by using the given instructions the referee should proceed wisely and impartially in the spirit of the basic principles outlined above 53 Appendix E Vega and the Dubov System The description of the FDS FIDE Dubov System in Appendix D states that in the Dubov system the player with a higher ARO will play against a player with a low rating and vice versa The preliminary tasks done by an arbiter before producing a pairing using such a system are the following 1 Calculate the Average Rating Opponent ARO of each player 2 Determine the due color of each player as in chapter 1 of the FDS 3 Put each player in a score group according to his score and due color With respect to the other Swiss systems the Dubov system requires more preliminary work if the arbiter is not helped by a computer In contrast the subsequent pairing is much easier to perform than other Swiss systems Standard case chapter 6 FDS Let s examine first the standard case i e that for which in a score group the number of white and black players is the same The next p
