Event: 2026 Clutch Chess: The Legends

How this was compiled: Checked on 13 September 2026, after the 12th and final game. Results, time controls and starting positions were read by us from the official Lichess broadcast PGN. The Clutch score was recalculated by us using the 1, 2 and 3 points per win published by the Saint Louis Chess Club, and matches the 8.5-3.5 reported by Chess.com at the end of day two; the winner is confirmed on the event's official page. At the time of checking, none of the sources consulted had published the final score in text. The moves 36.Re1 (game 9) and 26...Nf3+ (game 11) were measured by us with a local Stockfish 19 at depth 22, and undefended pawns in the starting positions were counted with python-chess.

The essentials in a few lines

• Topalov beat Kasparov 16-8 at Clutch Chess: The Legends in Saint Louis, with six wins, two losses and four draws across twelve Chess960 games, according to the official broadcast PGN; the Saint Louis Chess Club confirms Topalov as the winner.
• In Clutch Chess a win is worth 1 point on day one, 2 on day two and 3 on day three. On a plain count the match would have ended 8-4; the weighted 16-8 is exactly double.
• Each day used one drawn position. On day one no pawn started undefended; on day two, b2 and b7; on day three, with the knights in the queenside corners, a2, b2, a7 and b7.
• Measured by us with Stockfish 19 at depth 22: in game 9, Topalov's 36.Re1 took the evaluation from -0.08 to -8.66 and Kasparov won; in game 11, Kasparov's 26...Nf3+, played with 17 seconds on the clock, took it from +0.24 to +5.18 and Topalov won.
• The prize fund was $144,000: $70,000 for the winner, $50,000 for the runner-up and $24,000 in per-win bonuses of $1,000 on day one, $2,000 on day two and $3,000 on day three.

The score, day by day

The format, created by Maurice Ashley, is built against the early lead. A Sunday win is worth three Friday wins, so a match that reaches the final day with a five-point gap is still arithmetically open. This one was: after game 9, which Kasparov won, the gap fell to two points, and after the draw in game 10 it was still two, with two three-point games left.

Game 11 settled it. Topalov's win took him to 13 against 8, and the last game could be worth no more than three. Game 12, also his, only widened the score. Across the match Kasparov won twice, in game 4 (blitz) and game 9 (rapid); every other decisive game went to Topalov.

The proof that the scoring did not change the match is in the plain count. Six wins and four draws give Topalov 8 points; two wins and four draws give Kasparov 4. Clutch scoring turned 8-4 into 16-8: the same ratio with bigger numbers.

The three drawn positions

Our Chess960 guide recommends one count before the first move: how many pieces defend each second-rank pawn. Run on the three positions of this match, it gives very different answers. On day one no pawn started undefended. On day two, b2 and b7: the bishop on b1 sits behind its own pawn and does not protect it. On day three, a2 and b2 on one side and a7 and b7 on the other, because knights on a1 and b1 do not reach the squares directly in front of them.

In the four games of day three, the first piece out was not a central one. In three of them White brought a knight out of the corner by move four, always to b3, and in three Black did the same by move five. With knights in the corners the worst-placed piece was obvious, and neither player needed theory to work that out.

Counting undefended pawns reads the position; it does not predict the result. Topalov won games in all three positions, Kasparov in the first and the third.

Game 9: three swings and a last error

Game 9 was the least stable of the match. Topalov had a winning position and gave it back with 23.c7, which moved the evaluation from +3.14 to +0.38. Three moves later it was Kasparov's turn: at -4.24, 26...Bxg3 returned the advantage and left -0.32. The draw that seemed to be taking shape lasted until move 36.

The last error was the only one nobody gave back. With the rook leaving f1 for e1, the f2 square was no longer covered, and f2 is where the black bishop's diagonal to the king on g1 ran. 36...Bb6+ forced 37.Nd4, the two black rooks on the second rank gave 37...Reg2+, and after 38.Kf1 they collected the bishop on d2 with 38...Rxd2.

There was no opening theory in that game or in the other eleven, which was the point of the match. The errors that decided the last day were the kind every rapid player knows: a rook that stops covering a square and a check played because it was forcing. Chess960 removes preparation from the game; it does not remove the clock.

The move that closed the match: 26...Nf3+

Blitz players know the move: short of time, a check is the move that needs no calculation, because the reply is forced. The trouble usually comes one move later. After 27.Kg2 the knight on f3 went to d2, then b3, then back to d4, the square it had started from: four moves to return home while White played 27.Kg2, 28.Rc1, 29.Rc3 and 30.c5, hitting the bishop on b6.

The scoreboard made this error dearer than any other in the match. Before game 11 Topalov led 10-8. The win was worth 3 points and took the gap to 5 with only one three-point game left: the match was over before game 12 began.
