The win probability is the winner's chance of winning before the game, taken from the rating gap between the two players. The change is the winner's rating movement; the loser moves the same amount the other way. A game where the winner's pre-game probability was below 30% is marked as an upset (5 in this period). Jigo, no-result, default wins, handicap games, and games involving amateurs or foreign players do not move ratings, so no probability or change is shown for them.　Black and White are marked only for games whose colours were published, with BlackWhite.　The “last 5” column shows the two players' head-to-head results, oldest first, with this game at the far right. ○ = the winner of this game won, ● = lost, △ = jigo or no result, － = decided by default.

Players with at least 2 games between September 11, 2026 and September 17, 2026, ordered by how far their rating moved. “Before” is the rating going into the period; “after” is the rating following their last game.
