On the electronic scoreboard in Samarkand, after Round 4, the line for the United States women's team stopped at 15/16. Four boards per round, four rounds played, sixteen board points on offer, and they dropped exactly half a point. I sat with that number for a long while, not because it is beautiful — 93.75 percent of available board points is a level even the strongest national teams rarely touch after four rounds — but because it is almost impossible to verify. No player names. No pairings. No individual game cited. No opponents named. A single aggregate score sitting alone, exactly like a move lifted off the board and handed to strangers to guess.
What made me write this piece is not the number itself but the way it was packaged. The original I read carried a headline about the US women's team in Samarkand, while the entire body was a promotional description of Daniel King's Najdorf opening-video update. Two stories, two completely different levels of reliability, glued under one label. A skimming reader would assume the US women's team is winning with the Najdorf. Nobody wins with the Najdorf as White.

Samarkand and the board-point trap
Team events are a different sport from individual events, and this is where I want to linger longest. In an individual tournament, when a strong player wins repeatedly, you know exactly whom they beat, with which colour, and how the game opened. In a team event, board points are a collective unit of measure: a win is worth 1 point, a draw 0.5, a loss 0. A four-board team can score a maximum of 4 points per round. The US women took 15 of a possible 16 board points across four rounds, meaning that in 16 games played they won 15 and drew 1.
Arithmetically, that is an outstanding start. Informationally, it is a hollow shell. I do not know which board drew, which player drew, whether the draw came with White or Black, and most importantly — against whom. A draw against a 2600-rated opponent is a completely different signal from a draw against a 2300. The same half point, two opposite meanings.
In eight years of recording from the floor, I learned one principle: early-tournament board points are always inflated by the schedule itself. Team events pair by seeding coefficient, so Rounds 1 and 2 are usually where the strongest teams meet the weakest in the field. If 15/16 was accumulated across four rounds, it is very likely most of those points came from the first two — where the rating gap between boards can reach 200 to 300 Elo, enough for a 2500 to crush a 2200 without breaking a sweat.
I once wrote about another women's national team at an Asian team event that led after three rounds with 10/12 points, then lost two matches in a row against the two highest-seeded teams. The early number was not wrong. It simply had not answered the question fans actually care about: how good is this team when opponents stop standing still?
And this is the line I repeat every time I read a beautiful scoreboard: defence is not about massing pieces, it is about re-establishing space, square by square. Applied to a scoreboard, points are not class — they are the output of a pairing. Fifteen and a half points says the US women have not lost a game. It does not say they will win the next two rounds, when the schedule turns to teams with all four boards rated above 2450.
The Najdorf update: real value and advertised value
The other half of the original piece is where the genuine professional value sits, even though it was placed in the wrong slot.
Daniel King has updated his Najdorf opening-video set, and the description lists fairly specific branches: 6 h3 e5 7 Nde2, 6 Bc4 with English Attack ideas, 6 Be3 with ...a5, 6 Be2, and early f3 setups as well. For a Najdorf player on the Black side, this is not an unfamiliar catalogue. These are precisely the branches any serious player must have an answer to, because they appear in every major tournament.
To restate it clearly: the Najdorf is a principal Sicilian system, reached after 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6, named after Miguel Najdorf. It is one of the most heavily analysed openings in the entire history of chess. Anyone who has sat down with the Najdorf at 2400 level or above knows the feeling: you open a database, see the branch you play already has forty thousand games, and the sideline you were considering already has three thousand with a 52 percent win rate for White.
In other words, this is well-tilled ground. The value of a video update lies not in inventing something new — which is nearly impossible — but in re-ordering priorities for the student: which branches to memorise first, which can be skipped, and where the engine assessment has shifted since the original release.
What I rate highly here is the update structure rather than a remake. The original remains usable on its own, and the update supplements what has gone stale. For an opening product, this is commercially sensible design, because it does not force previous buyers to pay again from scratch. But it must be said plainly: the source material contains not a single metric by which to verify the quality of the recommended lines — no ACPL, no win rate, no frequency of appearance in recent elite games. With no data, all that remains is a sales pitch.
Where the blind spot sits
Where I disagree with the packaging is the new ideas label. In opening chess, new ideas have a very short shelf life. A branch advertised today can be refuted by a single elite game within three weeks, after which it becomes just another line of data in the database. Buyers are not purchasing truth; they are purchasing a snapshot in time.
One thing I always remind myself: no tactic is ever old — only the way you read the game can expire. The Najdorf update is not wrong, but if a student treats it as a fixed rulebook rather than a framework to re-check against the current engine, it will go stale exactly when they trust it most.
With the US women's team, the blind spot is even clearer. The 15/16 figure slides very easily into a they-are-dominating narrative, and that narrative will be tested over the next two rounds. If they meet a team with four evenly matched boards and the result is 2-2, the entire first impression collapses in an afternoon. That is not a paradox — it is the nature of team chess.
There is one more thing I want to state directly: I once spent half of 2026 rebuilding a prediction model for the opening rounds after the shutdown, and the biggest lesson was not that the model got 7 of 10 games right. The lesson was that early-tournament data always tends to tell the story the reader wants to hear, not the story that is happening. I threw out half my old dataset that year, and since then I have added a fixed section to every analysis, called data limits — where I state plainly what in a given number cannot be verified.
For Samarkand Round 4, that section would read: no player names, no pairings, no seeding coefficients, no colour distribution, no publication date. A list of blanks longer than the number itself. A scoreboard can lie, but the sequence of pairings behind it cannot.
What to watch
The next two rounds will answer the real question. If the US women hold above 75 percent board points against the highest-seeded teams, then 15/16 is no longer a lucky start but a statement about squad depth. If they drop a 2-2 match, the story flips entirely.
With the Najdorf update, the test is elsewhere: whether the lines 6 h3 e5 7 Nde2 or 6 Be3 ...a5 show up in elite games over the next two months. If they do, the product earns theoretical credibility. If they do not, it is only a pretty snapshot.
And the question I leave for myself, and for the reader: when a beautiful scoreboard and an opening update are packaged under one headline, are we reading news — or reading a sales page written in the shape of news?
