{In an event where Fabiano Caruana racked up seven victories, it's hard to
pick just one game to annotate. Yet this game helped Caruana both distance
himself from a charging Carlsen and hand Firouzja a second straight defeat
after a phenomenal start.} 1. d4 {Caruana has an increasingly diverse
repertoire. Perhaps in order to 'hide' his openings in anticipation of the
Candidates, in his earlier games with the white pieces he chose 1. d4 (against
So, round 1 and Anand, round 8), 1. e4 (Yu Yangyi round 3 and Dubov, round 7),
and 1. c4 (van Foreest, round 5). How was Firouzja expected to pinpoint his
opponent's first move?!} Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. h3 O-O 6. Be3 Nc6
{Firouzja plays a relatively rare line and catches Caruana by surprise. 6.. .
e5, 6...c5, and even the other two knight moves are far more popular.} (6... e5

when after either 8...c6 or 8...e6 9. Nf3 Nxf3+ 10. Bxf3 Nd7 has been seen.
Black will consider taking the knight on c3 with the prized fianchettoed
bishop to ruin the queenside pawn structure, but White has a nice spatial
advantage.} c6 (8... e6) 9. Nf3 Nxf3+ 10. Bxf3 Nd7) 8... Ned7 9. g4 {[#]
Caruana throws his pawns forward, trying to punish his opponent's youthful
exuberance. White seizes space in the center and on the kingside, whereas
Black has a lead in development. The major downside for White is that hasty
expansion regularly results in a pawn structure prone to collapse.} c6 10. Nf3
cxd5 11. cxd5 b6 {Firouzja blitzes out a novelty. On the surface this looks
like a terrible move. After all, Black voluntarily cedes control of the c6
square and appears to be strategically lost. But Firouzja studied the opening
in depth and uncorked an important - and very necessary - piece sacrifice,
collecting a number of pawns in the process.} ({The strong British GM Gawain
Jones obtained an overwhelming advantage after GM Antonios Pavlidis tried}

attack, and so is the white king. White is completely lost.}) 20... Bxd4 21.

Black's pieces swiftly come alive. A great example of a position where piece
quality takes precedence over piece quantity.} (22. Qxd6 Qf6 ({It's possible
that} 22... Qxd6 23. Rxd6 {was reason enough for Caruana to avoid entering

In a critical moment, Firouzja makes an extremely logical move, but one that
puts him permanently on the defensive. The objective evaluation - with the
assistance of an engine on - might not instill fear, yet the path forward
becomes clearly easier for White, who has a beautiful blockade and control of
the light squares. Importantly, Black has to push his kingside pawns as a
defensive maneuver, which opens his monarch to a swift attack.} (27... a5 28.
