In a small chess club at the end of an alley on Petrogradsky Island, in the middle of winter, I once sat for a long time watching a man close to seventy place his black d-pawn on d5 as his very first move. 1.e4 d5. He did not hesitate. He had played that move for four decades, and the board in front of him always looked like a familiar room: cramped, dim, but with a seat he knew exactly how to find.
After that game he told me something I have never forgotten: “I don't need to win the opening. I only need not to lose there.”
This winter, the online chess-training market has released a product built on exactly that spirit: a 60-minute video course presenting “an idea in the main-line Scandinavian Defense” for Black, delivered by IM Andrew Martin, FIDE Senior Trainer. The promotional copy places Magnus Carlsen's name right next to the title, along with the claim that the world champion has used the idea to win games.
No opponent is named. No date is given. Not one line of engine evaluation appears. And that is where the real story starts.
The Scandinavian Defense, also called the Center Counter, is the move 1...d5 against 1.e4. It is one of the oldest recorded replies to 1.e4: the position appears in the Göttingen manuscript, one of the oldest surviving chess documents, dated to roughly the end of the 15th century. The name “Scandinavian” is tied to the Danish and Norwegian players who brought it into top-level practice, with Bent Larsen the most frequently cited; later, Sergei Tiviakov was the grandmaster most closely associated with the system for decades.
Structurally, Black trades the central pawn immediately. After 2.exd5, Black has two main directions: recapturing with 2...Qxd5 and accepting that White will gain development with tempo, or 2...Nf6 and regaining the pawn with the knight. In the most common branch, 3.Nc3 forces Black's queen to choose a square: 3...Qa5, 3...Qd6 or 3...Qd8. Each queen square creates a position with a completely different personality. On a5 the queen pressures the queenside and keeps invasion chances; on d6 it is more flexible but easier for White's developing moves to target; on d8 it is the most modest option, conceding nearly all tempo but keeping a healthy pawn structure. Behind that, Black's plan usually follows a familiar template: ...Nf6, ...c6, ...Bf5 or ...Bg4, ...e6, ...Bd6, ...Nbd7.
That template explains why the Scandinavian thrives at club level and fades as the level rises. At club level, a clear plan is worth more than a small space advantage. At grandmaster level, a small space and development advantage is exactly what gets used to squeeze an opponent over the next forty moves.
Based on my experience covering games at club events and opens around Saint Petersburg, I would argue the Scandinavian is one of the rare openings in which an amateur can reach a “not bad” position on memory alone. But precisely for that reason, it is also the opening most likely to lull a player to sleep. When the board empties, memory starts scoring — and at club level, memory often scores more than people expect.
The first thing to state clearly about the 60-minute course: the promotional material names no concrete move. Not one line of variation, not one game reference, not one branch. The phrase “an idea in the main-line Scandinavian” could mean 3...Qa5, could mean 3...Qd6, or could mean a whole system built around the ...Nf6 move order. These branches are not the same in character, in skill requirements, or in risk. A buyer cannot know what he is buying until he clicks pay.
In chess publishing, that kind of promotion is normal. But it sets a clear limit: without a move order, the objective strength of the system cannot be evaluated. Everything that follows can only be a judgment about method, not about a variation.
Three claims in the introduction deserve to be separated and examined: “simple and very solid,” “Black's life becomes easy,” and “it is doubtful whether White can get an advantage.” This is marketing language, not a theoretical conclusion. There is no engine check, no database statistic, no sample game for the reader to verify. In chess, an unsupported claim can still be true — but it cannot be confirmed, and those are two very different things.
The interesting word is “solid.” In practice, the solidity of an opening is rarely a property of the moves themselves. The solidity of an opening does not live in the move; it lives in how many of the opponent's sidelines the player has answered. A system is solid only for the player who has prepared for every transposition, and becomes fragile the moment the opponent steps outside the book.
In the main line of the Scandinavian, the claim that “White can hardly get an advantage” needs careful reading. The mainstream theoretical consensus at the top level does not say White is held to a draw; it says White keeps a small space and development edge, not enough to win automatically but enough to play on for hours. The distance between “White cannot win” and “White has no advantage” is the distance between a technical fact and an advertising line.
The second issue is format. Sixty minutes is an introduction format, not a repertoire format. A Black player who wants to use the Scandinavian seriously must have answers to 2.Nf3, to 2.d4, to 3.Bb5+, to 3.Nf3, to the 4.d4 branch after the queen leaves d5, to transpositions into Caro-Kann-like structures, and to games where White declines the d5 pawn to keep the centre. No 60-minute video covers all of that. That does not make the course worthless; it simply means the product is a starting point, not a suit of armour.
Behind the technical claims sits a perfectly reasonable commercial argument. Club players do not buy theory; they buy a reduction in the number of decisions they must make in the first fifteen moves. A system coded into a few simple plans has higher practical value than a system that is objectively stronger but demands thirty hours of study. That is why short formats exist, and why they sell.
And Carlsen's name? Magnus Carlsen has played almost every opening at some point in his career, usually to avoid an opponent's preparation rather than to prove a system's theoretical worth. The fact that a world champion used an idea in one game says nothing about whether that idea suits a 1400-rated player. But in marketing it is a very powerful trust anchor — and a trust anchor always pulls attention away from the analysis.
The biggest blind spot here is not in the opening. It is in the question the buyer is trying to solve. In club chess, most points are lost after move twenty, not in the first ten. A good opening course can still be the right answer to the wrong question, and the buyer will not find out until he loses a game in which he played the opening perfectly.

The promise of “playing with confidence the same day” is the riskiest line in the entire pitch, because confidence arrives before competence. A player who finishes 60 minutes will enter the next game feeling he understands, then stop calculating exactly when calculation matters most. At the same time, the label “solid” can quietly become a licence for passivity. I have watched too many games in which Black played the Scandinavian by the book for fifteen moves, then lost on move forty-one because nobody taught him how to convert “solid” into “winning.”
And the last, small but persistent blind spot: in chess, authority is the weakest form of evidence. A coach with a FIDE title and a world champion who once played a move are two real facts, but neither replaces an engine check and a sample of games large enough at the target player's level.
The true value of 60 minutes is not the opening system it delivers. It is the habit it starts: the habit of sitting down after every game, writing out the line the opponent chose, and answering the question nobody else will answer for you. An opening repertoire only matures when the player begins to edit it himself. An old bird understands that landing is also a way of flying — and in chess, landing means learning slowly.
The chess course market is where people sell the future to buy hope. If a system were truly solid, would it need to borrow the name of a world champion to be believed?
