Left out of the statistics: FM Mashala Kabamwanishi – John Costello — the broadcast did not record the moves that were played. The result 1–0 stands (verify, 27 Sep: board 85.2 Kabamwanishi – Costello scored 1-0 (chess-results agrees) but the relay's moves end 52. Kxe3 with Black +8.42 and 24:14 on his clock, after a run of moves that swing the eval by fifteen pawns; the relay mis-registered moves).
Played, per the official results: Abon Arelong – Lesly Nompavos ended 0–1; the broadcast marks it unplayed and has no moves (chess-results, round 11, board 103.3).

moves of opening

moves of endgame
Averages per game, with the phases split as Lichess splits them. 85% of the games reached an endgame; the first capture came on move 7.1 on average.
| Endgame | Reached | At the end |
|---|---|---|

A rook endgame has nothing but kings, pawns and rooks left; the others likewise, as the Lichess puzzle tagger defines them. A game can pass through several types, so the first column adds up to more than the games.
Each band runs from the games that reached the endgame to those that still had it on the last move; the rest went on into another type. One scale for both columns.
