2015 Peoria City Championship Details and Pairings updated 03/24/2011

(Actual pairings are at the bottom of the page.)


Once again it's time for another Peoria Championship. 


This year the games are scheduled every other week beginning April 6th.  See the schedule here.   The games will be played on Monday night at HyVee unless the players involved agree to other arrangements before that night.  Signed Score sheets indicating the winner should be turned in for possible publication and tournament records. PGN files will be accepted (encouraged) in place of the hand written score. Please indicate if you would not like your games annotated for the GPCF web site.


The format is a little unusual, so let us explain how it all comes together.


12 qualifying players are divided into 2 sections of 6 players each. Each section plays a round robin and the section winners then meet in a match to determine the winner.

Assigning Players to Groups A and B.


Our goal is to have two reasonably even groups based on average rating. We do this by first selecting players in order of their rating and assigning them to group A or Group B.


For the first two players, we arbitrarily assign the highest rated player to Group A and the second to group B. So Group A received the highest player in position 1 of the six selections.


If we continue to alternate Group A and Group B (ABABABABABAB) in this way, then, for each of the six selection pairs, Group A will always get the higher rated player. To make it more fair and even out the ratings between the groups, we instead allow Group B to have the higher rated player in every other pair of selections (ABBAABBAABBA). This guarantees a more even and fair spread of players between the two groups.

Assigning Players Games and Colors.

This year we have simply used our computer software Swiss-Sys version 9 to make the round robin pairings using the built in randomizer.



If there is a tie between the top two players for a group, the two players will play another game, this time with colors reversed from their original encounter. If three players tie, the two lower rated players play a play in game with reversed colors and the winner then faces the highest rated player of the 3, again with colors reversed. If there are 4 tied, play in games are 1v4 and 2v3 with winners meeting, again all games are with colors reversed. If there are 5 ties, players 4 & 5 play in to the 4 player field and the winner plays 1. If there is a draw in the first playoff game, another game is played, again reversing colors. If that too is drawn, 2 more games are played at G30+5 and another 2 possible games at G5+3. If ties remain thereafter, a coin flip or other random selection is made with both players present. The G30 & G5 games will all be played in a single meeting.


The Finals Match.


The winners of the two groups meet in a final match. It takes at least 2 points and a lead in score to win the match. Possible scores are 2-0, 2-1, 2.5-.5, 2.5-1.5. If the score is tied at 2-2, we again go to a possible 2 games at G30+5 and 2 games at G5+3, played in a single meeting. The higher rated player receives White in the first game, colors are alternated thereafter.

Ratings Used.


All ratings are the most current available, taken from the rated events, often more recent than the latest published rating.


So here are this years pairings.
