Standings
Still perfect
Teams that have taken both match points in every round (the heavy line) and teams simply never beaten (the thin grey one), of 189 in all. The counts halve every round, so the scale grows with the square root; every count is written in. A team that sat out a round leaves the heavy line and stays on the grey one.
After round 11, no team is left on a perfect score; 2 teams unbeaten. Point at a round to name the teams that fell there.Tap a round to name the teams that fell there.

Up the rating ladder
Every finished game by the average rating of its two players, in steps of 100: how often it was decided, how White scored, how accurately both sides played (Lichess’s accuracy, analysed games only). The grey rule is the whole event; steps with fewer than 30 games are hollow.
The numbers

Which openings won
A bar per family: White’s wins, the draws, Black’s wins. The tick is the family’s score for White, the grey line the event’s; a tick right of it, and White did better than usual. Framed in red, the best for White and the best for Black of the families with at least 20 games. Each round keeps its 25 most played families, so the rarest are counted short.
