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 (6 in this period). Jigo, no-result, default wins and handicap games do not move ratings, so no probability or change is shown for them. Amateurs are rated together as a single pooled entry. 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.

Tournament names are shown in Korean, as the Korea Baduk Association writes them, unless an English name is known.

Round names are translated from the Korea Baduk Association's wording; those we cannot translate are left in Korean.
