In a wild evening of Chess960 on Lichess, cheaven claimed first place in the Freestyle Friday Swiss tournament, finishing with 4 points from 5 games and the highest tiebreak score of 11. The road to the title was anything but smooth — a stunning last-round upset at the hands of underdog SidAhu had everyone watching. Here's how it all went down.

Chess960 has a way of separating genuine understanding from memorized theory, and Freestyle Friday's format — a five-round Swiss on Lichess — proved no exception. With ten players, a 5+2 time control, and a fresh random starting position every game, it was anyone's tournament.
cheaven came in as the highest-rated active participant and played like it, dispatching three opponents with clinical precision before surviving a nerve-wracking endgame against XROL on the clock. A perfect 4 points from 5 rounds — and a tiebreak score of 11, well clear of second-place binyamash's 7 — made cheaven the undisputed winner.
But the tournament's most memorable moment had nothing to do with the champion's victories. It came in the final round, when SidAhu — rated over 500 points lower than their opponent — delivered a checkmate for the ages.
Starting from position 245 — bishops and knights swapped from their classical squares — cheaven opened 1. e4 and was immediately gifted an inaccuracy when Fula_710 played 1...b5?!, a speculative flank pawn push that left their queenside underdeveloped.
The game's critical moment came on move 5 when Fula_710 played 5...Nb6?? — a blunder that gifted cheaven a near-winning advantage of +4.73 according to the engine. The knight headed for the wrong square at exactly the wrong time, leaving the queen on a5 without adequate support.
cheaven shifted gears and launched a kingside storm with Bxg6, ripping open the g-file and exposing the enemy king. After 17. Qxg6+, Fula_710's king was forced to wander. A rook sacrifice, queen infiltration through g7, and a relentless piece co-ordination left no escape. The finish — 26. Qxc7# — was as clean as checkmates get.
The longest game of the tournament — and arguably the most chaotic. mi11l0o played a double-fianchetto setup with 1. f4 and g3, but a critical blunder on move 14 (a4?? instead of the better Bd4) handed cheaven the initiative in a position where every tempo counted.
What followed was a wild endgame full of mutual mistakes. Both sides blundered mating nets — cheaven famously had a forced mate in 5 on move 20 with Qxc3+ but played Nxg2?? instead, letting mi11l0o escape. The engine swung wildly as both players navigated pawn endings with under a minute on the clock.
In the end, with bishops, pawns, and a completely won endgame, cheaven simply outplayed their opponent on the clock. mi11l0o ran out of time on move 58 in a position that was already beyond saving — down material in a rook-less pawn ending with Black's pieces dominating every file.
This one was over almost before it began. Starting from position 728, the early middlegame was nearly equal — both sides inaccurate, the engine hovering near zero. Then on move 9, binyamash played 9...Kb8??, an inexplicable king walk that sent the evaluation rocketing to +4.67.
cheaven responded with 10. O-O-O — themselves blundering back momentarily — but binyamash obliged with another mistake: 10...Rd8?? instead of the needed d6 to consolidate. The engine jumped back to +5.14 for White.
After 11. Ng3, binyamash surveyed the position, saw no path forward, and resigned. It was the shortest decisive game of the event, a reminder that in Chess960, misjudging king safety in the opening can be instantly fatal.
Position 944 gave both sides a most unusual setup — two bishops on the first rank hemming in the knights. XROL opened with 1. b3 and 2. h4, an aggressive flank approach. cheaven countered quietly with 1...e5 and 2...h5, matching aggression.
The decisive blow came on move 8: 8. Ne4?? walked directly into 8...Bxe4, dropping a piece into an already uncomfortable position. From that point, cheaven never let up. A minor piece harvest continued throughout the middlegame — bishops, knights, and rooks all fell to coordinated Black pressure.
The pièce de résistance: on move 32, Black's passed h-pawn marched all the way to h1, promoting to a queen before being captured — but the damage was already done. cheaven won on time at move 40 with a material advantage of several pieces and a position the engine rated at nearly -8 for White.
Already crowned by tiebreak before the final round even finished, cheaven entered this game as a massive favourite — rated 555 points above SidAhu. What followed was a masterclass in resilience, and a reminder that ratings mean nothing once the clock starts.
cheaven played an ambitious kingside expansion with 1. g4, soon building what should have been an overwhelming position. By move 14, the engine gave White a stunning +6.64 advantage — an almost insurmountable lead. But then came the pivot: 15. Qb7+?? — a catastrophic blunder that flipped the evaluation to -4.47 in a single move. The queen was misplaced, the king exposed, and SidAhu never looked back.
What followed was a masterful demonstration of technique under pressure. SidAhu — playing Black from an unusual starting position — calmly stripped cheaven's pieces away one by one: Qxb2, Qxb1+, Qxc2, a bishop pair harvested, pawns advanced. cheaven's king was chased across the board, from e2 to d3 to c4 to b5.
"cheaven had a winning position for 14 moves. SidAhu needed just one gift — and when it came, they converted without mercy."
The finale was poetic. With cheaven's king stranded on a6 — its own pieces scattered and helpless — SidAhu delivered 47...Qa4#. Checkmate. A king that had tried to run found no shelter. The rating swing was seismic: cheaven lost 112 Elo; SidAhu gained 96.
It was the kind of game Chess960 was made for — no theory, no preparation, just pure chess. And on this night, the underdog played it better.
cheaven deserves full credit for the tournament win. Four points, the highest tiebreak score, and three clean victories against players rated between 1500 and 1650 tell the story of a player who understood Chess960 positions better than the field. The games against Fula_710 and XROL in particular showed a sophisticated grasp of piece activity and endgame conversion that went well beyond rating.
But the tournament's lasting image will be SidAhu's checkmate. In Chess960, any position can become a trap. Any game can turn. And that, ultimately, is the beauty of Freestyle Friday.
