4545 Team League: Season 6

There are several reasons why a pairing might not end up being played, including scheduling difficulties, a lack of available replacements, or one of the players not showing up at the start time!↩︎

The number of games played in this statistic can differ from the number of games played in the season, as it excludes games where the result of the pairing was later changed to a forfeit win or loss.↩︎

Note that these performance ratings only account for account games played on a specific board, so they differ in this respect from the performance ratings published on the Lichess4545 rosters page.↩︎

“Plus” score = played wins - played losses. Also, these season scores exclude any unplayed games, forfeit results or byes.↩︎

A game’s total clock time is the sum of both players’ move times from move 2 onwards.↩︎

For these statistics, a played opening line is termed a gambit if it arises from an opening or variation that’s commonly associated with one side sacrificing some material in the opening (in return for compensation) and the side that played the gambit actually sacrificed material in the game (for at least 5 consecutive half-moves before move 16). In particular, the list of gambit openings isn’t restricted to named gambits; it also includes for example the Marshall Attack in the Ruy Lopez, the Budapest Defence, and several variations of the Two Knights Defence in the Italian Game. However, this approach excludes games where a side decides to gambit material when not playing a traditionally gambit-associated opening. Yes, those should be considered gambits. But they’re not here.↩︎

Qualifying “gambiteers” are ordered by number of gambit games played before percentage score.↩︎

Archbishop of Accuracy: this is for the player with the lowest average centipawn loss (CPL) over all games. Note that this calculation isn’t based on Lichess’s ACPL figures. It excludes moves played in the first 10 moves of a game and moves with a centipawn loss < 150 in decided positions. These are considered to be positions with an evaluation greater than or equal to +300 centipawns for one side. All evaluation data is sourced from Lichess server analysis. To be eligible, players must have played at least five games in the season. David Award: the player whose opponents achieved the highest percentage score across the season, excluding games against the player. One’s opponents must have played over 20 games (against others) to qualify. Suggested by Tranzoo. Egalitarian Award: intended for the team whose players performed most similarly to each other. First, I compute all players’ relative performance ratings – the difference between their actual performance rating (using FIDE’s method) and their initial rating. Then I group all players by team, and give the award to the team with the lowest standard deviation across its players’ relative ratings. Suggested by Silkthewanderer. Gambit Guru: most gambits played while scoring above 50%. MVP Award: minimum 5 games played. Rookie Award: minimum 4 games played. Saved by the Bell: Excludes moves made in positions with an evaluation of under +300 centipawns from the mover’s perspective. Ordering is determined first by # moves played with under 5 seconds remaining, then by least time remaining in such conditions, then by worst eval faced. Slingshot Specialist: the player with the highest total rating gap between their opponents and themselves when only considering wins against opponents rated at least 50 rating points higher.︎↩︎

The season performance ratings presented in this report may differ slightly from ratings published on the Lichess4545 website, but both calculations are based on FIDE’s preferred method, and both exclude unplayed games such as forfeit wins/losses and scheduling draws.↩︎

Season ACPL here excludes the first 10 moves of a game, all zero-CPL moves played in zero-evaluation positions, and moves played in positions where one side has an advantage of +300 centipawns or greater that aren’t mistakes or blunders.↩︎

I award “comeback points” for each game that a player won after their opponent had an advantage of at least 300 centipawns, according to Lichess’ server analysis. The scoring is rather simple. A win after suffering an evaluation disadvantage of more than 6 pawns earns 1 point. A win after being down by 3-6 pawns earns 0.7 points. A draw after being down more than 6 pawns earns 0.5 points. A draw after being down 3-6 pawns earns 0.3 points. Then the points are added up.↩︎

Excludes moves made in positions where the mover had an objective advantage of +3 or greater. Players are first ordered by number of moves made with 5 or fewer seconds remaining, then by least time they had left (across all qualifying moves), and finally by the worst objective evaluation they faced (again across all moves).↩︎

For example, this report excludes from its analysis all games of less than 5 plies (half-moves), games that ended in a disconnection or by “cheat detected”, games that were aborted, and games that started from a custom position.↩︎

However, players who were banned from the Lichess4545 leagues after finishing a season in the top three places are still shown with a podium place in that season’s report.↩︎
