The play/draw analogue in chess is white/black, and it is fairly easy.Quote from Thursdayisgod »The LGS I play it runs a monthly modern 1k of almost exclusively local guys, very few travelers, considering pushing for a coalition for using the chess p/d system, anyone have experience/advice for running an event with that system?
Here is fide's document on how to do pairings: https://www.fide.com/component/handbook/?id=85&view=article
The article is a bit technical but gives you all the information you need. Here is some of the most important:
In the first round the colour assigned to player No.1 shall be decided by drawing a lot. All other odd numbered players in the top half of the initial list shall receive the same colour.
The difference of the number of black and the number of white games shall not be greater than 2 or less than –2.
A player shall not have the same colour three times in a row.
After pairing two players’ colours shall be assigned based on giving descending priority to:
giving both players their due colour
equalizing the numbers of black and white games played before
alternating the colours of both players regarding the first difference of their colour history going back from the previous round to the first round.
assigning his due colour to the player with the higher SB
assigning his due colour to the player with the higher Buchholz, and so on."
It's a bit hard to explain how to do it by hand in text form, but with any chess tournament organizing software you can do play/draw assignments and pairings automatically.
To summarize: Start the event by seeding all players (randomly given no ELO or other score to seed with) and randomly assigning player 1 the play/draw. Then, each odd numbered seed also gets the same allocation, and the even numbers the opposite. Then the pairings just need to be readjusted every round so that you follow the alternating play/draw system (5.4) while keeping each player in their SCORE GROUP (i.e the group of players who have the same score).
