Taimanov, Møller and the Move Sequence That Exposes a Chess Course

Winter in Saint Petersburg, January, the Neva frozen into a long grey mirror stretching to the horizon. I sat in front of the screen, a cup of tea long gone cold, and in my inbox there was a familiar notice: a new chess course had just been released. The title hit my eyes first — Svitlana's Smart Moves, The Taimanov Sicilian. Sixty minutes. One opening. One presenter. I opened the material, mostly out of professional habit after nearly half a century of reading chess, and then I stopped.

The move sequence given in the description was: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.e5. I read it a second time. Then a third. White's first move was e4, which is true of most open games. But Black's first move was e5, not c5. And anyone who has ever held the pieces in a Sicilian Defense knows one simple thing: the Sicilian begins with 1...c5. The Taimanov Sicilian, the name printed in bold on the title, begins with 1...c5 and then 2...e6. The move sequence before me did not pass through the c5 square even once.

That was the moment I realised I was reading a mistake. Not a small typo one could overlook. A mistake of identity.

To understand why this deserves an article, a little context about the names involved is needed.

Mark Taimanov was a Soviet Grandmaster, and also a concert pianist. He belonged to a generation of players for whom chess and music did not exclude each other but nourished each other. The Sicilian variation attached to his name, 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6, is a solid, flexible system that has appeared at every level of competition for decades. It is not a wild opening. It is the opening of people who know exactly what they want, accepting a tight structure in exchange for endurance.

Evgeny Sveshnikov was another Russian Grandmaster, the man attached to the Sveshnikov Sicilian. In the course material, Sveshnikov is cited as a player who used the line in this course with very good results. And John Møller was a Danish player, the man attached to the attack named after him in the Italian Game.

Three names. Two entirely different opening worlds. One course standing between them.

That is why I stayed seated in front of the screen that winter afternoon. Because when an educational product misnames itself, the question stops being about a single course. It becomes a question about how a small industry — the chess-teaching industry — operates. And as someone who has followed chess since 2026 as a player and then a tournament organiser before moving into media, I realised I had seen this pattern many times, only it had never been exposed quite so clearly.

Let us begin by identifying what that move sequence actually is. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.e5 — this is the Møller Attack, a sharp line within the Two Knights Defense. Even without starting from the Italian Game, a player can reach this position through a different move order in the Scotch Game: 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Nf6 5.e5. This variety of move orders is a fascinating feature, showing that the Møller is not a dead end but a junction lying inside several classical systems.

The technical heart of the matter is this: the move 5.e5 is not merely a pawn advance. It is a declaration. The pawn steps forward to claim space, attacks the knight on f6, and immediately creates tactical tension that forces Black to react. White accepts structural concessions — the d4 pawn has been captured, the position may leave long-term weaknesses — in exchange for attacking chances. It is a calculated gamble, and the Møller name is attached to it not by luck but because its viability has been proven across decades.

Black has several sound replies, and the course material lists three main directions: 5...d5, 5...Ng4 and 5...Ne4. These are not three equivalent branches of one position. They lead to three positions of fundamentally different character.

5...d5 leads to a closed centre, a positional struggle in which Black grabs space and White must find compensation through piece activity. It is the coolest direction, built on defence and counterattack.

5...Ng4 creates direct pressure on f2, opening an attacking race between the two sides. The knight leaps out, threatening the sensitive squares around the white king, and the game can become a contest of speed.

5...Ne4 leads to a semi-open situation, where the black knight settles on an outpost and seeks counterplay.

Three directions. Three different psychologies. A sixty-minute product claims to cover all three. This is the point where I want to linger a little longer, because the structural differences between these three branches typically demand a substantial volume of analysis. A closed-centre branch, an attacking-race branch, a semi-open outpost branch — each has its own network of variations, its own tactical patterns, its own typical mistakes that club-level players need to be warned about. Compressed into sixty minutes, one should expect an outline-level sketch, not a deep excavation. That is not a fault. But it needs to be said plainly.

The material's description of the line as sharp is entirely accurate. Its claim that Black cannot easily equalise also has a basis. At grandmaster level, those statements hold. But between grandmaster level and club level lies a gap that many courses sold to improvers rarely spell out.

Let us talk about the club player. The material positions the course as suitable for this group, and calls the opening relatively easy to learn. In terms of memorisation, that is true. Sharp sequences tend to be highly forcing, with few choices, making them easier to remember than sprawling positional systems with hundreds of small branches. But there is a paradox anyone who has sat at a real board knows: easy to learn does not mean easy to play, and in this case the two even pull in opposite directions.

A sharp opening places the entire burden of calculation on the player holding the pieces. When you play a slow system, you have time to think, to adjust, to make a mistake and still recover. When you play a forcing system, you enter a narrow corridor where every move must be precise. The opponent can step out of the book with an unexpected move, and then you stand alone in a position you do not fully understand, because you learned it as a sequence of moves rather than as a structure with logic. The course material itself admits this in one line: problems are being posed that over the board might prove very tough to solve. That is a discreet confession of asymmetry. White gets to attack, but the practical difficulty falls on both sides depending on who steps out of preparation.

And here the story leaves the board and enters the market. The transfer market is where people sell the future to buy hope. I always thought that sentence was true of football until I realised it is just as true of the chess-opening market. A chess course sells you a future: the future of a player with a weapon in hand, with an opening plan that forces the opponent to think. The buyer pays to buy the hope of becoming more dangerous. That is a reasonable transaction, as long as both sides understand what they are exchanging.

The problem lies in the identity of the goods. When a course carries the name Taimanov Sicilian but its content is the Møller Attack, the buyer searching for Sicilian material is led elsewhere, while the buyer searching for Italian Game material may never find the product. In a market where discoverability decides sellability, this is a double loss. The seller loses the chance to reach the right audience, and the buyer loses time walking through the wrong door.

Having followed chess games and chess products for many years, I have found that discrepancies of this kind are rarely random. They tend to reflect a market logic: a familiar name sells better than an accurate one. Taimanov Sicilian is a widely recognised brand, attached to a legendary Grandmaster, attached to memories of major tournaments. The Møller Attack, though no less rich in history, is little known outside specialist circles. Forced to choose between two names, commercial pressure tilts toward the one that sells more easily. That is why I believe this mislabelling is not an oversight but a symptom. It shows that the chess-opening industry operates by brand logic more than by technical logic, and that has consequences beyond a single product.

Once you see this, you view the chess-course market with different eyes. Sveshnikov is cited as a credibility anchor, and that is entirely understandable — using a famous Grandmaster to confirm an opening's value is a standard marketing technique. But when the material says he used the line with very good results, the question becomes: results at what level, in which tournaments, across how many games. That is not a nitpick. It is a question about reliability. Club players have a right to know whether that endorsement came from the big stage or from smaller events, because the practical applicability differs enormously.

Sveshnikov, after all, was a Soviet and Russian Grandmaster peaking around 2580 classical Elo, and a recognised Sicilian specialist. That a player like him occasionally played sharp lines in the Italian Game and Two Knights is entirely plausible stylistically. It is said that what belongs to a sharp, concrete Sicilian specialist can also appear in a sharp Italian opening. The argument sounds coherent. But coherent does not mean proven.

Here I want to pause at what I consider the most important point of this whole story, and it concerns neither Taimanov nor Sveshnikov. It concerns the reader.

An empty stadium — memory remains. I once wrote that sentence in 2026, when the stands were deserted and I sat alone in my Saint Petersburg newsroom, listening to the wind moving through the empty rows. Back then I learned that chess, like football, does not need spectators to exist, but it needs memory to have meaning. And the memory of an opening is built from real games, from real decisions made at the board, not from names pasted on to make things sell.

When the stadium no longer holds a ball, memory begins to score. In chess, when the moves no longer match the name on the title, the learner's memory begins to record defeats whose cause they cannot understand. They learned the correct move sequence. They did exactly what the course instructed. But they do not understand why the correct move is correct, because the product did not teach them the identity of the system — it taught them a brand instead of a structure.

There is one more aspect I want to raise, somewhat counterintuitively. People tend to think a naming mistake is a small problem, fixed with an edit. I do not think so. A naming mistake in chess education is a cognitive problem, not merely an editorial one, because the name shapes how the learner organises knowledge in their head.

When you learn an opening under the name Taimanov Sicilian, your brain files it in the Sicilian drawer. It is linked to 1...c5, to characteristic defensive structures, to a network of memories of Sicilian games you have watched. When you actually play the Møller sequence beginning with 1...e5, you are playing an open game, but your memory has stored it in the Sicilian drawer. This mismatch creates a silent cognitive disturbance. When the board opens in the e5 direction, you do not have the matching memory patterns ready, because you were never taught that you are in the Italian Game. You learn correctly but file it wrongly.

This is why I believe the episode deserves to be recorded as a small milestone in chess-education history. It is a case study in what happens when commercialisation overtakes accuracy.

I do not want to end with an indictment. The people who make chess products are workers in a brutally competitive market, where the ability to attract attention decides survival. No one stays up late to mislabel a product they care about. But precisely because of that, consumers need to be equipped with a filter. And the filter begins with a very simple question anyone can ask before buying a chess course: does the move sequence in the title actually match the move sequence in the material.

As I write these lines, the Neva is still frozen. The chessboard on my desk is still set, a white knight on f3, a black pawn on e5. It is the position of an Italian opening, not a Sicilian Defense. There is nothing wrong with the Italian Game. It is a great opening, with a rich history and sharp branches powerful enough to hurt any opponent. But it needs to be called by its own name.

And perhaps, in an industry where memory is the primary raw material, calling an opening by its correct name is also a way of respecting the people who created it. Mark Taimanov was a Grandmaster and a concert pianist. John Møller was a Danish player with an attack named after him. Both deserve to be remembered for exactly what they left behind. Memory never takes a red card, but it also does not forgive names placed in the wrong drawer.

From here on, I think every club player can draw something larger than the story of a sixty-minute course. It is this: when you choose an opening weapon, do not choose the name that sounds familiar. Choose the structure you genuinely understand. An opening called by its correct name will teach you how to think. An opening called by the wrong name only teaches you how to trust blindly.

And in a long winter in a northern city, when the chessboard is the only companion still awake with you, the only thing that truly matters is that you understand which move you are playing, and why.
