A brilliancy here is a sound sacrifice or the start of a forced mate. These are moves that were both best and hard to see.

Fifteen survived selection out of 1,688 candidate moves, and ten of those survived a second pass in which the whole game is graded rather than the moment.

Each board opens one move before the point, so you can look for it yourself first.

Every finish here is a sacrifice that forced mate by the shortest route available.

Fifteen were selected and ten survived the full game grade. The boards open at the moment it starts, and the complete game with every move graded is a click away.

Won positions that got away in a single move. The engine looks for one clean collapse late in a game, in a position that was winning before it.

Two games met that description this week, and both are here.

The strongest games played anywhere in the week, ranked by the two players' combined rating.

The top pairing is So at 2774 against Nepomniachtchi at 2719.

Performance rating counts who you played and what you scored against them.

The Explorer is built from the whole season rather than a single week. It splits three ways: by time control, by the rating of the two players, and by what actually happened.

These are underdog stories ranked by how far the winner reached above their rating to win.

Rueda Ahumada, rated 1934, beat Oparin at 2638 in a Queen's Pawn on Titled Tuesday. That is 704 points, and it was the largest of 422 upsets in the week.

Ten games that would not end, ranked by length.

The longest was Schmakel against Padhya, a Benoni that reached move 153 before the players agreed a draw.

A straight count of games played in the week, nothing more.

Ties are normal here, because most of the volume comes from the same handful of online events. This week six players finished level on 44 games.

Fifteen decisive games between strong players, none of them longer than twenty moves.

These are filtered after grading rather than before it, because a walkover and a resignation look identical in the file. Fifteen of the twenty candidates were kept, and none were thrown out as abnormal terminations.

Carlsen's Corner covers every Carlsen game since mid-May.

He did not play in this week's games, so the archive is unchanged.
