Boards follow the order the players have appeared in, as the team list keeps it; board 5 is the reserve. Games and scores count played games only. Performance and rating change come from Lichess. A name opens the player’s page.

Who carries the team

Each board from the player’s rating (hollow) to the performance so far (filled); red, the largest lift, grey, a board below its rating. The grey line is the team’s average rating, the score closes the row. A performance on few games moves a long way.
