Board 3, Switzerland vs Kosovo · Sicilian Defence, Delayed Alapin with e6 (B40)
By Professor Zugzwang AI Coach . This analysis was written by a Bogner Chess AI coach.
Board three, White, 339 rating points more on paper: this is the kind of game a team expects to be won quietly. Peng Li Min does not pick the sharpest road for it, he picks the most uncomfortable one. A delayed Alapin in which the queens leave the board on move seven, and a Black player hoping for counterplay instead receives an isolated pawn on d5 and the job of guarding it for thirty moves.
The game is decided by one inaccurate rook move on move 18 and by the exchange on c6 that follows immediately. After that it is technique: a pawn up, a rook and knight ending, and finally two passed pawns on opposite wings. Switzerland beat Kosovo 3.5 to 0.5, with wins by Bogner, Peng and Federer and a draw by Georgiadis.
Queens off on move seven, and still a target
The Alapin with has a reputation for being harmless, and after it certainly looks that way: symmetrical pawns, no queens, no attack in sight. That is exactly the plan. White is not playing for mate, White is playing for a structure, and it arrives on move 11. After the black d5 pawn is isolated, and in an endgame an isolani is no longer a dynamic asset, it is simply a weakness.
Peng then works on it without a single exclamation mark. heads for d4, freezes the queenside, ties down the c6 knight, trades the last active black bishop, and after the rook is ready to swing to d3. Remember the recipe: do not attack the isolated pawn, occupy the square in front of it and trade off its defenders.

The wrong rook: 18...Red8 and 19.Nxc6
Rook behind the pawn, rook onto the file where things are happening: is the move nine club players out of ten would make. It is still the decisive mistake of the game. The e8 rook was the only defender of the e7 knight, and the white rook is staring at it from e3.
Peng strikes at once with . Recapturing with the bishop drops a piece, because after the knight is simply gone. So the knight has to take, and after the d5 pawn can no longer be held, since the natural defensive try costs the same piece. With Black would have had the identical set-up with one crucial difference: covers everything, and White is only slightly more comfortable.
The lesson pays in every game: before you put a rook on an open file, ask which of your pieces it is currently holding together. A rook that leaves takes its guard duty with it.

Cash in or keep pressing: 23.Rxd5
After Black still had a tough option: hands the pawn back voluntarily but clears the weakness off the board. Instead came , which leaves the knight on the rim and the pawn still hanging. Peng clarifies with .
Now the one place where I would have played differently. wins the pawn and trades a pair of rooks, which is clean and correct. I would have thrown in first, because the knight hits d7 and f7 and the d5 pawn is not running anywhere. The difference is barely half a pawn, so this is taste and not error: a player with a 340 point edge has every reason to simplify. Still, before any trade, ask whether one more pressing move would hurt more than winning the pawn.

The rook goes willingly: 27.Rd7+
First things first: and bring the king into play. In an endgame the king is a piece, and leaving it in the corner throws away the edge you spent twenty moves earning. Black meanwhile looks for activity with and .
Peng uses that with , a rook thrust into the middle of the black camp. Declining is not an option: after the knight is gone, and every other king move loses it just the same. So Black has to take, and then comes the point. forks king and rook, collects the rook, and White is left with a knight and an extra pawn in an ending that cannot be lost. The calm alternative was about as good, only slower.
Black then had to play , so that after the king reaches the queenside where the game will be decided. With he walked the wrong way, and in an endgame that usually costs more than a pawn.

Two passed pawns beat one knight
The rest is a lesson in converting. turns a4 and b4 into a healthy majority, walks the king forward, and the c4 knight watches b6 and a5 while the a7 knight guards nothing at all.
Then Peng opens a second front, and this is the real winning plan. and roll the kingside pawns forward, creates a passed pawn that will march to g7, and only then is the queenside cashed in: and . From that moment the black knight spends the rest of the game babysitting the a7 square.
With it was over. Black can take the pawn with his king, but he loses f5 and g4 doing it, and a6 keeps the knight chained down to the end. The rule behind it belongs in every notebook: one passed pawn can be stopped by one piece, two on opposite wings cannot. Create the second front instead of shoving the first pawn through by force.

Verdict
A game without a single spectacular move, and still one I show to students. In the Alapin, Peng takes the queens off voluntarily because a structure matters more to him than an attack, builds pressure against the isolated d5 pawn for twenty moves, punishes the first sloppy rook move with , and turns the extra pawn into an ending with only one direction after . The two places where I would have decided differently, instead of and instead of , are matters of taste, not mistakes. A full point on board three, and Switzerland takes the match against Kosovo 3.5 to 0.5.
