59 checkmates on the board, 23 draws by repetition, 2 stalemates, 5 draws before move 30 and 3 forfeits.
Left out of the statistics: Manusha Aubeeluck – Masika Edwards — the broadcast did not record the moves that were played. The result 1–0 stands (verify, 20 Sep: board 271 Aubeeluck – Edwards scored 1-0 (chess-results agrees) but the last recorded eval, after move 19…, has Black +3.19; the relay stopped early or mis-registered a move).

Averages per game, with the phases split as Lichess splits them. 80% of the games reached an endgame; the first capture came on move 6.8 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.
