Week 5 Pairings

Week 5 will be played on Monday, January 5 at Bellevue High School.  (Note the change in location, to facilitate the make-up match already played.)

WEEK 5 PAIRINGS (Seed in brackets; score in parentheses)
WHITE Result BLACK
Interlake A [1] (18.0) Interlake D [12] (11.5)
Redmond [2] (14.0) Bellevue [7] (10.5)
Eastlake [8] (10.5) ICS [6] (10.5)
Overlake [4] (9.5) Interlake C [5] (10.0)
Skyline [11] (9.0) Interlake B [3] (10.0)
Issaquah B [13] (5.5) Issaquah A [10] (9.5)
Bothell [14] (3.0)  1 – 4* Mercer Island [9] (8.5)

*Match played Monday, December 15 at Mercer Island High School due to transportation logistics for Bothell High School on Monday, January 5.

Pairing issues were numerous.  Normally, only the teams towards the very top or very bottom have significant pairing issues.  In this case, because of the number of close results, there were also issues in the middle.  Here are the notes:

  • Interlake A [1] and Redmond [2] have already played in Week 3 and cannot be paired again.  Interlake A plays against the third-place team in the league, Interlake D [12] (!).  Since Interlake D has already had three whites; they must play black.
  • Redmond [2] gets one of the teams in the fourth-place tie.  They have already played ICS, so the highest-seeded team remaining is Bellevue [7].  Both teams had the same WBWB color pattern, so the higher seed alternates.
  • ICS [6] and Eastlake [8] is the natural pairing of the teams remaining.
  • Interlake B [3] and Interlake C [5] are the two teams at 10.0, and they played each other previously.  Interlake B has already played each of the next two teams in line also, and gets Skyline [11].  Skyline has already had three blacks; they must play white.
  • Interlake C [5] gets Overlake [4], the team next in line.  Both are due White, but Interlake C has had their second-to-last white more recently than Overlake did.
  • The lowest team that Bothell [14] hasn’t played is Mercer Island [9].  The lowest team that Issaquah B [13] hasn’t played is Issaquah A [10].

As announced on Monday’s e-mail, blitz tiebreaks will decide if there is a tie for who qualifies for the round-robin and who doesn’t.  The only exception will be if both Mercer Island (now at 12.5, but won’t be present on January 5) and Overlake (cannot be present on January 12) both are involved in the tie.  Since both teams can’t be present on the same date, computer tiebreaks will break the tie in this instance.

KingCo Playoff Information

As we get closer to the playoffs, a few key pieces of information for players and coaches alike to be aware of:

  • Interlake C and Interlake D will not participate in our playoffs this year, as State Team regulations prohibit them from qualifying for state.

Championship Round Robin

  • The top four teams remaining (there is a possibility one or both of Interlake C and Interlake D could be in the top four) will qualify for the State Team tournament on Friday, February 27 – Saturday, February 28, and will play a round-robin for the following three weeks.
    • If teams faced each other during the regular season, their colors will be reversed in the playoffs.
    • If teams did not face each other during the regular season, their colors will be paired using the format for determining colors for the Swiss.  The colors for the round-robin will be posted before it begins.
    • Teams will be seeded #1-4.  Tiebreaks will be decided by blitz if they determine who will qualify for the round robin.  If the tie only determines seeding within the round robin, computer-based tiebreaks will be used.
    • The first round of the playoff will feature 1 vs. 4 and 2 vs. 3.
    • The second round of the playoff will feature 1 vs. 3 and 2 vs. 4.
    • The third round of the playoff will feature 1 vs. 2 and 3 vs. 4.
    • Total game points from the round-robin will determine the top four places in KingCo.  The KingCo champion is the team that has the most game points in this round robin.

State Qualifying Bracket

  • The remaining eight teams will be placed into the bracket.  Of these eight teams, four will qualify for State.
  • Teams will be seeded #1-8 based on their regular season finish, with #1 being the best seed.  Ties for a seed will use computer-based tiebreaks.
  • Colors for matches will be the reverse of any regular-season matches between the two teams.  If the two teams have not played, colors will be determined by the colors that would be appropriate if the teams were paired using the Swiss System.
  • The bracket will feature three rounds of chess.
  • In the Bracket Quarterfinals, the following matches are played:
    • Match 1: Team 1 vs. Team 8
    • Match 2: Team 2 vs. Team 7
    • Match 3: Team 3 vs. Team 6
    • Match 4: Team 4 vs. Team 5
  • In the Bracket Semifinals, the following matches are played:
    • Match 5: Winner of Match 1 vs. Winner of Match 4 (winner qualifies for State)
    • Match 6: Winner of Match 2 vs. Winner of Match 3 (winner qualifies for State)
    • Match 7: Loser of Match 1 vs. Loser of Match 4 (loser cannot qualify for State)
    • Match 8: Loser of Match 2 vs. Loser of Match 3 (loser cannot qualify for State)
  • In the Bracket Finals, the following matches are played:
    • Match 9: Winner of Match 5 vs. Winner of Match 6 (winner will receive the 5th place trophy at state; both teams qualify for State)
    • Matches 10 and 11: The Loser of Match 5, the Loser of Match 6, the Winner of Match 7, and the Winner of Match 8 will be re-seeded by regular-season standing.  The highest-seed remaining will play the lowest-seed remaining, unless these two teams faced each other in the Bracket Quarterfinals; in this event, the highest-seed remaining will play the second-lowest-seed remaining.  The other two teams remaining in this group will play.  Both winners will qualify for State.  Both losers will not.
    • Match 12: Loser of Match 7 vs. Loser of Match 8.  (Neither team qualifies for State.)
  • Some of you may recall needing a fourth round in the bracket last year; that was because only three bracket teams qualified for State that year.

Computer-based Tiebreaks

These tiebreaks will be used in situations where only seeding is determined, in this priority order:

  • Head-to-head.  If more than two teams are tied, this tiebreak is won by the team who defeated each of the others in the tie or lost by the team who lost to each of the others in the tie (a head-to-head sweep).
  • Modified strength of schedule.  Calculated by taking the game points earned against a team and multiplying by the number of game points that opponent earned, summing the results for all five rounds.
    • Example:  ICS, Bellevue, and Eastlake are all tied for fourth place after four rounds.  Eastlake has not played either of these teams, so a head-to-head sweep does not apply.
    • ICS scored 5 points against Issaquah B (5.5 points), 1 point against Redmond (14 points), 1.5 points against Bellevue (10.5 points), and 3 points against Overlake (9.5 points), so their tiebreak score would be (5.5 * 5) + (1 * 14) + (1.5 * 10.5) + (3 * 9.5) = 85.75.
    • Bellevue scored 5 points against Bothell (3 points), no points against Interlake A (18 points), 3.5 points against ICS (10.5 points) and 2 points against Interlake D (11.5 points), so their tiebreak score would be (5 * 3) + (0 * 18) + (3.5 * 10.5) + (2 * 11.5) = 74.75.
    • Eastlake scored no points against Interlake A (18 points), 3 points against Skyline (9 points), 2.5 points against Mercer Island (8.5 points), and 5 points against Bothell (3 points), so their tiebreak score would be (0 * 18) + (3 * 9) + (2.5 * 8.5) + (5 * 3) = 63.25.
    • As it stands now, ICS would win this tiebreak.  Bellevue would be second on this tiebreak.  Keep in mind that each of the four opponents listed above would earn points in Week 5, changing these totals.
  • Match points.  Whichever team has scored the most match points (1 point for each match with 3 or more game points, 0.5 point for each match with 2.5 game points, 0 points for each match with 2 or fewer game points) will have the best tiebreak.
  • Strength of schedule: Just like the above, but does not take into account your team’s result; it sums the points earned by your opposition.  Known in more formal chess circles as the Solkoff.
  • Most blacks.  The team that has the higher number of games with the black pieces will advance.
  • Coin flip.

Blitz Tiebreak Protocols

This tiebreak will be used if one team (or multiple teams) will advance while one team (or multiple teams) will not advance.

  • If there are only two teams in the tiebreak, the team with the higher seed will get to pick their color White or Black and will play that color on boards 1, 3, and 5.  If the blitz match is tied 2.5 – 2.5, the match is considered to be won by the team that played Black on boards 1, 3, or 5.
  • If there are more than two teams in the tiebreak, colors will be assigned by lots and the teams will play a round-robin blitz tiebreak.  Total game points will determine who advances.

*Match was held between Interlake C and Issaquah C and is used as a placeholder result due to Interlake D’s late entry into the league.

Week 4 Pairings

Week 4 will be on Monday, December 8 at Issaquah High School.  Games take place in their Black Box Theater.  Just a reminder that no food or drink (including water) is permitted inside the theater space.

WEEK 4 PAIRINGS (Seed in brackets; score in parentheses)
WHITE Result BLACK
Interlake A [1] (13.0) Interlake C [5] (10.0)
Interlake B [3] (9.0) Redmond [2] (10.0)
Interlake D [12] (8.5) Bellevue [7] (8.5)
ICS [6] (7.5) Overlake [4] (7.5)
Issaquah A [10] (6.5) Skyline [11] (7.0)
Mercer Island [9] (6.0) Issaquah B [13] (3.0)
Bothell [14] (3.0) Eastlake [8] (5.5)

Most of the pairings follow standard conventions, but a few notes for the pairing aficionados:

  • Interlake A [1] (13.0) and Redmond [2] (10.0) already played in Week 3 and cannot play again during the regular season.
  • Issaquah B [13] (3.0) and Bothell [14] (3.0) already played in Week 2 and cannot play again during the regular season.
  • We have two cases of schools getting a 3-1 color split:
    • One occurs in Interlake D versus Bellevue in Match 3.  Both teams had the WBW colors, and one team needed to get a third white.  I did check to see if moving a team up or down a table could potentially mitigate this; the problem is that both Redmond (in Match 2) and Overlake (in Match 4) both had the same color alignment.  By convention, the higher-ranked team alternates.
    • The other is with Issaquah A and Skyline in Match 5, this time with one team getting three blacks.  In this case, Issaquah A had already played black in consecutive weeks (in weeks 2 and 3), and by conventional pairing rules is prohibited from having three in a row of the same color.  (Skyline had black in weeks 1 and 3, and will be getting white in week 5.)
