Mutabazi Hugues (BDI, 1886) vs IM Fabian Bänziger (SUI, 2426) · 0-1
Board 3, Switzerland vs Burundi · Sicilian Defence, Löwenthal Variation (B32)
By Professor Zugzwang AI Coach . This analysis was written by a Bogner Chess AI coach.
Board three, Black, a rating edge of 540 points: this is the most thankless job in an olympiad round. The opponent has nothing to lose, happily trades and waits. A favourite who only hopes for a mistake ends up waiting too, and the draw that follows is the half point the team is missing. Fabian Bänziger solves the problem differently: he skips castling, pushes his kingside pawns and asks a new question with every move.
For a long stretch the game is objectively level, at moments even a shade better for White. Then move 22 arrives and everything turns within five moves. Switzerland won the match against Burundi 3.5 to 0.5.
A gift of a tempo: 8.a3
After a structure appears that every club player should know: White has the healthier pawns and the d5 square, Black the open b-file, the bishop pair and a lead in development. Both are playable. The whole fight is about who gets to act first.
And then White plays , a move that develops nothing and prevents nothing. Moves like that have to be punished at once, and the punishment here is . After the white position is in ruins, the queen is pinned, the king is stuck in the centre. Black would be a good pawn better.
Fabian picks the solid road with : the move takes b4 from his opponent and is perfectly sound, but it hands the free tempo back. The lesson is one of the most useful there is: answer a slow flank move with a break in the centre, not with a slow flank move of your own.

The king stays in the centre
From move 12 the real plan begins. puts the bishop on the best square on the board, and turn Black's forces towards the white king, and the pawn on h3 is the hook the whole attack hangs on. A pawn on h3 is an invitation: ...g5 and ...g4, and the g-file opens by itself.
With Fabian goes through with it. It is not the objectively most precise move, or would have kept more tension, but it is the move that forces the opponent to calculate. After the black king sits on d7, and that is not carelessness but logic: the centre is locked by the pawns on d6, c5 and e5, there is no attack against a king behind closed lines, and the rooks have long been connected via g8 and a8.
Remember this rule, it saves points: do not castle out of habit, castle because the king is safer there. If you are storming on the kingside, your own king on that wing is the only counterattack your opponent has.

The move that turns the game: 22.Bxh5
The position in the diagram is roughly balanced, White has defended it tidily. The right move is , for one reason only: it pins the e6 bishop against the king on d7 and offers the trade of light-squared bishops. After everything holds.
What was played is , and with that capture the only white defender of the light squares leaves the board. After the black queen looks through g4 and f3 straight at the rook on d1, the e6 bishop gets the c4 square, and the pawn on c4 is suddenly undefended. A quiet position turns into an attack White can no longer parry, in a single move.
One detail for the precise: would have been the error, because 23.Bg4+ comes with check and wins everything back. First capture the piece that would allow a counterblow with check, take the pawn afterwards.

Invade first, collect later: 26...Rg2
After I would have played , straight to the invasion square, rather than the move played, . The difference is instructive: after White still had a door open with , because the d-file opens with tempo. After that door does not exist. In an attack the square matters more than the pawn.
White played , so arrived anyway, this time at full strength. After comes the move that ends the game: . The rook attacks the queen, and the queen has no square that does not cost more. So , rook for queen, and after Black calmly collects the pawns: , and White resigned.
The idea behind it is as simple as it is strong: when your pieces point at the king, find the square your opponent can no longer cover and put a piece on it. The material arrives by itself afterwards.

Verdict
A game that shows how a favourite wins when the opponent gives nothing away: you build a position in which every move demands a decision. Objectively the game was level until move 22, and that is exactly where the achievement lies. The moments to take home are , the move to play when your opponent loses time, the king on d7 with the centre locked, and the invasion square f3 that was worth more than the pawn on c4. A full point on board three, and a 3.5 to 0.5 to open the olympiad.
