Season report: LoneWolf (U1800) Season 19

The forfeit rate is the percentage of pairings that didn’t result in a game being played.↩︎

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.↩︎

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

Currently, gambit openings are identified by the presence of the term gambit in the opening name assigned by Lichess. This is admittedly an imperfect approach as it excludes certain openings that should also be considered as gambits such as the Marshall Attack.↩︎

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

Archbishop of Accuracy: lowest average centipawn loss (ACPL) over all moves played, as determined by Lichess’s server analysis. Minimum 100 moves played. 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 the figures given by the Lichess4545 website. Both figures are based on FIDE’s preferred calculation method and exclude unplayed games (such as forfeit wins/losses and scheduling draws.↩︎

Both the statistic and the name of its associated award – the David Award – were suggested by Tranzoo.↩︎

Originally suggested by Lou-E. This table shows players ranked by the size and number of comebacks achieved over the course of the season. For this purpose, the size of a comeback has been defined as the difference between a player’s final score in a game (0, 0.5, or 1) and the worst evaluation during the game that they faced (which is then converted into a rough win probability for their opponent). For example, if I were to win a game after Lichess’s server analysis gave my opponent a 75% chance of winning in a certain position, then I would have earned 1.75 comeback “points” from the game. My opponent of course would have earned zero points. If the game had been drawn, I would have instead earned only 0.75 comeback “points”.↩︎

Statistic suggested by Silkthewanderer.↩︎

Excludes moves made in technically winning positions, defined as $\tt eval \le 300$ (from the mover’s perspective). Players are first ordered by number of moves made with 5 seconds or fewer remaining, then by least time remaining in such conditions, and finally by worst eval faced.↩︎

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.↩︎
