Nakamura wins with 1.Nh3; Nepo to face Carlsen

"This one time," said Nakamura to the camera as he did not stall a game out on time

Hikaru Nakamura reached the Speed Chess Championship Semifinals after defeating Fabiano Caruana 18.5-8.5 while playing a buffet of unique first moves: 1.c3, 1.h3, and mostly 1.Nh3 with White and 1...a6, 1...h6, and 1...e6 (followed by 2...a6) with Black. Ian Nepomniachtchi beat Arjun Erigaisi by just one point, 15.5-14.5, to set up a World Championship rematch in the Quarterfinals against Magnus Carlsen.

The score on between the two American champions was quite evenly matched in blitz. Fabiano Caruana led their head-to-head by one point, but it was virtually even. Curiously, they hadn't met in the SCC for six years.

After both commentators marveled at Hikaru Nakamura's peak bullet rating (3570, what?!), Korley aptly summarized the task that befell Caruana in this match: "If Fabiano wants to take this, he's gonna have to do his work early," suggesting that Caruana needed to take the lead in the blitz because he was not exactly the favorite in the bullet segment.

As it went, Nakamura led by three points at the end of the 3+1 blitz segment. From there, we saw the Nakamura bullet train roll once again as he stretched out the margin by another seven points.

5+1: Nakamura 4.5-3.5 Caruana

From his first game, playing 1.c3 in the opening, it was clear that Nakamura's opening bingo series was not over. He was up against one of the world's most prepared players, and so playing offbeat moves from the first move was more likely to be an actual match strategy than a publicity stunt. (It does still make for great content though.)

Caruana won the first game after the 5-time SCC champion missed the tactic 30...Rd1!, and the white position crumbled immediately.

Had Caruana been more attentive to mistakes such as this one, and been just as incisive in converting the advantage, he would have had a much higher score later on in the blitz segments. He left too many points on the table later on by missing such wins.

Of course, that is easier said than done!

Nakamura won the next two games in a row to take the lead. Then, in Games 4 and 5, we started to see the contours of Caruana's tilt take shape.

In Game 4, he was absolutely outplaying Nakamura and had every objective and practical chance to win. But then he allowed his knight to get trapped and lost the game. In the clip below, you can see Nakamura look at Caruana's camera in disbelief.

Nakamura then should absolutely have lost Game 6, where Caruana failed to convert the advantage of two extra pawns. The 2018 world championship challenger walked into a threefold repetition by accident.

Caruana nicely won Game 7, where even having an extra bishop in the endgame did not make the win easy. It looked like he was losing control with under 10 seconds left, but the reigning U.S. champion sailed through the storm and attained the full point.

With a draw in the last game of the segment, they concluded with the closest score they'd have for the rest of the match.

3+1: Nakamura 5.5-2.5 Caruana

The previous segment was Caruana's best, and it slowly went downhill from there as the time controls became faster. The points he left on the table certainly came back to haunt him, and Nakamura showed no mercy in the games he pressed for victory.

In the first game, they reached a position that Caruana should theoretically never lose. With Black, he had four pawns against a piece. Because White had no pawns left, Black could even blunder all four pawns away and it would still be a draw.

Unfortunately, there were still rooks on the board as well and you can't get away with blundering a rook!

Nakamura was again dead lost in the second game—his king was just a single move away from annihilation. It was another point left on the table and another instance where a win for Caruana may have changed the psychological trend of the match.

In the following position, Korley instantly blurted out the winning move 37.Rxb7, without seeing the engine. Naroditsky later agreed that under normal circumstances, Caruana would have played it instantly—but the psychological trend of the match played a role.

Hesitation crept in, and Nakamura thrived on the indecision. Instead of being checkmated, Nakamura traded queens and escaped into an opposite-colored bishop endgame. Another half-point saved from what we can in good conscience call a dead lost position.

Nakamura won two consecutive games before playing out what is now the longest game in SCC history. It took 204 moves of shuffling in a drawn rook endgame to drain the match clock—as Nakamura explained later, from his perspective, a legitimate match strategy to decrease the number of games in the match when he's ahead.

By the time Nakamura won his fourth and last game in the segment, even Caruana smiled as he dropped a full rook and was suddenly down five points in the match.

Caruana won the last game of the segment. It was a 25-move miniature and an opening disaster for Nakamura, who was finally punished for playing 1.e4 a6 with the black pieces. But it was still little consolation, as Caruana entered the bullet segment with a four-point deficit.

1+1: Nakamura 8.5-2.5 Caruana

As predicted before the match, the bullet portion was where Nakamura shined most. Out of 11 games, there was one draw.

If one was hoping for a Caruana recovery, the first game was a bad omen. Nakamura still had 57 seconds on his clock after winning, meaning he played the whole game making almost all of his moves in under a second.

After a draw, Caruana won his first bullet game—with a bishop and outside passed a-pawn against a knight in the endgame.

Nakamura won the next six games. The second game in that streak was, in one sense, the most crushing because Caruana found a great (and winning) tactic with 18.Bh6!. But after Nakamura's 18...g6, he played the natural 19.Bxf8, missing the strong response 19...gxf5! with tempo.

In a span of two moves, White went from having a winning attack to losing material.

Caruana's only other win came in the last game, but the match had been finished for quite a while already.

In the interview, Nakamura shared some interesting insights. Asked about his—how shall we say—unique opening choices, he reminded us that he's not the only one to play like this: "There's a certain former world champion who does the same thing, maybe not as often," hinting at Carlsen who plays all sorts of adventurous first moves.

He also shared that he stuck with 1.Nh3, instead of 1.c3—which he only played one time—because he was "worried" Caruana may have spoken to Levon Aronian during a break "and come up with something to do against it."

Oh, and who's the best bullet chess player besides Carlsen and Nakamura? He says Nihal is a contender, but "without a doubt" Ding Liren.

Nakamura earns $6,740.70 and Caruana makes $1,259.30 by win percentage. In the Semifinals, Nakamura will play the winner of Vachier-Lagrave vs. Nihal.

Nepomniachtchi 15.5-14.5 Arjun | RO16

Robert Hess and Benjamin Bok commentated on this match.

Replay all the Nepomniachtchi-Arjun games on chess24.

Two-time world championship challenger Ian Nepomniachtchi was not originally one of the 16 players in this year's SCC, but he was a last-minute replacement after Ding Liren's last-minute withdrawal from the event.

A few weeks ago, Nepomniachtchi, with a post on social media, showed he was feeling a bit left out. Just as Ding was a last-minute replacement in the 2022 Candidates Tournament—and, in a sense, in the 2023 world championship (for Carlsen)—we see the tables have turned.

Since then, his recent tournament victories have been quite a statement. He won Division II of the Julius Baer Generation Cup two weeks ago. This week, he won the early Titled Tuesday. His match victory over Arjun on Thursday was perhaps another statement: Carlsen, you're next.

Nepomniachtchi led the head-to-head encounters with Arjun on by more than double Arjun's score.

20-year-old Arjun, the Indian no. 5, won the 2022 Junior Speed Chess Championship. Nepomniachtchi was predicted to be the favorite, although juniors are always improving and can be unpredictable, as we saw in this match.

SmarterChess predicted a slight advantage for the world no. 2 in the two blitz time controls. It was sort of correct; Nepomniachtchi only won the 5+1 segment by one point, and the other two were tied in score.

5+1: Nepomniachtchi 5.5-4.5 Arjun

The first segment was a seesaw of momentum—a statement that would actually describe the entire match. Arjun took an early lead, but after a close struggle, Nepomniachtchi finished the segment ahead by one point.

Nepomniachtchi won the first game after his speedy play—having nearly two minutes against 30 seconds—provoked a decisive mistake. One game later, though, he laughed and took a sip of tea as he resigned on move 13.

Arjun took a one-point lead in the next game, but it didn't last; one erroneous decision instantly shortened the life span of his king.

Arjun then lost on time in a position where he had a winning advantage, but after a draw, he brought the score back to the balance by using two minor pieces to outplay a rook in the endgame.

The last game allowed the Russian no. 1 to take a one-point lead before the next segment. With Black, he played the thematic break in the center, 29...d5!, followed by 31...fxg4! sacrificing the exchange. Although Arjun tried his best to confuse the situation, Black broke through without any delay.

3+1: Nepomniachtchi 5.5-5.5 Arjun

A significant lead (of more than two points) remained elusive for both players for the rest of the match. Just as one won a game or two, the other would return the favor. They made a draw in the first game, but the next 10 were decisive.

The first four of those decisive games were black wins, alternating between each player. The very first win for Nepomniachtchi in this segment was a shocking one. Arjun grabbed an undefended knight in the center of the board—as if, to pick up a dollar bill, running onto train tracks. Nepomniachtchi played the last move of the game with a sinister grin.

Back and forth they went. Nepomniachtchi had just taken a two-point lead by winning the fourth of those consecutive black wins, but then he disconnected and lost on time. Arjun won the next game with the white pieces, the first of four consecutive white wins.

In that game, the Indian prodigy first found the knife-like 25.Bd5! to begin the king hunt. He chased the black king from the kingside all the way across the board to b7.

One more beautiful game was Nepomniachtchi's last victory with the white pieces. He sacrificed the exchange for total control with the dark-squared bishop; in reality, it can hardly be called a sacrifice. The bishops, raking across the chessboard in the final position, are a sight to behold.

GM Rafael Leitao breaks down the details from start to finish in the annotations below.

The last two games ended with a black win for each player, including a dramatic finish that went in Nepomniachtchi's favor.

With 23.Qh4?? Arjun, behind the white pieces, created a mate-in-one threat. Both players were ready to deliver checkmate. And yet it was Black's turn.

That meant the 3+1 segment of the match ended in a tied score—meaning Nepomniachtchi was up by only one point heading into the bullet games.

1+1: Nepomniachtchi 4.5-4.5 Arjun

Another hard-fought segment decided the match only in the final game, which Nepomniachtchi won. We were a game away from entering the second overtime this season.

After two draws, Arjun broke the ice by winning three consecutive games and taking a two-point lead. He won a piece in the first game, won on time in the second, and he found some nice geometry to win the third.

LPDO means Loose Pieces Drop Off. This concept was quite relevant in that third game, where an undefended rook left the board.

And then, true to the way this match had been going, Nepomniachtchi won two in a row himself to even the score.

Then came a draw. There was one bullet game left. A single win here meant winning the match, and a draw would take us to overtime. The game turned on the position after Nepomniachtchi's 26...h5.

Nepomniachtchi takes home $4,550 for winning the match and Arjun receives $1,450 by win percentage.

The bracket currently looks as follows, with Hikaru Nakamura and Wesley So the two players already through to the Semifinals.

There's another double-header on Friday September 15:
