The document outlines the rules for Baldwin High School's chess club ladder competition. It describes the initial Swiss-style tournament (SLQ) to determine initial ladder positions. It then explains the monthly Ladder Board Meetings (LBM), including how games are paired and how ratings and rankings are adjusted based on results. Challengers can improve their ranking by beating higher-ranked opponents or drawing against them. Exceptions apply if challengers are on the same rung or directly below their opponent. Players must defend their ranking at least once a month.

Swiss Ladder Qualifier (SLQ)
The first competition of the year will be a Swiss Pairing System Tournament to
determine initial ranks on the club’s Ladder Board. Initial placement will be
according to ratings after the SLQ. The ratings will be calculated based on games
won, lost or drawn and the appended SLQ Ratings Table. All players are rated 1200
initially and re–rated at the conclusion of each round of the SLQ.
The Tournament Director will announce when the SLQ will be held. For
example:

Ladder Board Meetings (LBM)
After the SLQ, there shall be at least one Ladder Board Meeting (LBM) per
month. For the first round of each LBM, matches will be arranged on a first–come–
first–served basis. In the second round, all the higher ranked players from the first
round select their own opponents. Subsequent rounds will be paired by a lotto system
(all players put their name in a box, names will be selected from the box at random
and two at a time for pairings). Every game will affect the Club Rating, but not
necessarily the Ladder Board Ranking. LBMs will consist of games of one time
control announced by the Tournament Director. The time controls may be G/5, G/10,
G/15 or G/30 (please see the attached Rating Tables). LBMs will start with a general
meeting of the club membership on an as–needed–basis.
Your LBM Responsibilities
At Ladder Board Meetings, the Tournament Director will announce the time
control.
It is the responsibility of both players to logon to USChessLive with the screen
name bhs + first name + last initial. No foul language will be tolerated online or off.
Chess is a sport, kindly adopt the attitude of a good sportsman.
The responsibility of the Challenger is to set–up the match by clicking on the
opponent’s screen name and specifying only the time control. Choice of color will be
randomized.
Upon conclusion of the game, it will be the responsibility of the Opponent to
print–out a score of the game and give it to the Tournament Director.

Ladder Rules
Change of Club Ratings
Ratings will be adjusted after each Ladder Board Meeting based on games won,
lost or drawn using one of the attached ratings charts. Ratings do not influence ranks
except in the initial SLQ.
Change of Rankings
There will be no penalty when losing or drawing a match for the higher ranked
player.
There will be no award when winning a match for the higher ranked player.
If the lower ranked player, the challenger, wins the match, this player will be
awarded a new rank half–way between the current rank and that of the opponent.
If the challenger draws the match, this player will be awarded a new rank one­
quarter–way between the current rank and that of the opponent.
If the challenger losses the match, this player will not be awarded a new rank.
EXCEPTION1: If the challenger is on the same rung of the ladder as the
opponent, then winning the game causes the two players to swap ranks. Further,
drawing the game will cause the challenger to assume the rank directly below the
opponent!
EXCEPTION2: If the challenger is ranked directly below the opponent,
then winning the game causes the two players to swap ranks. Further, drawing the
game will not cause a rank adjustment!!
EXCEPTION3: If you do not defend your position on the ladder board at
least once a month, your rank will be reduced by the number of months that you have
not defended your rank!!!
Ladder Board Set–up
Every player will have an index card on the Ladder Board with their name,
club rating, rung, rank, date of last defense, and W–L–D–T record (wins, losses,
draws, total number of games). These cards will be arranged with the higher ranked
players on the top on a bulletin board in Room 429:
Rungs Ranks
A: 1
B: 2 3
C: 4 5 6
D: 7 8 9 10
E: 11 12 13 14 15…
