Preparations for Tournament at CCA

Making preparations for the 3 Player Chess Tournament this weekend online and at the CCA in Glasgow.

I'm looking for an appropriate existing tournament system to use or to hack.
After a quick Google search on Chess Tournaments, this is the set of assumptions that I am starting out with.

Tournament systems are competitive mechanisms. They are very rarely authored. They do not credit their inventors. They have the authority of law. They determine and regulate the levels of competition between a community of players. They seek to balance the rewards for winners against the despair of the bad player to heighten the drama, sustain the tournament and to find the best man. Step on the head of the guy in front to get a look at the pot of gold at the end of the rainbow.

Tournament systems promoted by groups like the US Chess Centre sell on the "sophistication" of their mechanisms.

"The USCF developed, and is constantly modifying, a sophisticated rating system for its members. By playing in tournaments, players earn a rating, which rises each time a player wins, and falls each time a player loses. The rating of the opponent is the major component of the formula."

The main elements are:

Rounds- a pre agreed number of games to be played by each player
Ratings- this affects pairings of players
Scoring - lose=0 draw=1/2 win=1
Byes and withdrawals- dealing with non-programmatic tendencies and Asymmetry in the group of players.
Tie-breaks- when players share the same scores
Awards ceremony- where every competitor receives some recognition but the winner receives the most

These elements are what influence the health of the chess players' data body.
