Last Thursday I reopened a game on an online server I have been tracking for months. It lasted eighteen moves. Black's second move was 2...d5. White answered 3.exd5 in under two seconds, purely on reflex. By move eighteen White was out of material, and in the chat window nobody mentioned the second move. I rewound three times — not to find the losing move, which sat somewhere in the middle, but to see clearly the moment a pawn was given away on move two and nobody called it by its right name.
That is why I stopped at the Elephant Gambit this time.
ChessBase has published the latest entry in its "Tips for Beginners" series, part thirty-one, with "LiveBook" in the headline. The product is a sixty-minute video by Andrew Martin building a Black repertoire after 1.e4 e5 2.Nf3 d5!?. This is the Elephant Gambit, also known as the Queen's Pawn Counter-Gambit, generally filed in the ECO C40 region — a King's Pawn opening that turns hard away from every mainstream branch. Martin is an English International Master and a long-standing ChessBase author. His name on the cover surprises nobody. Neither does the fact that the publisher both promotes and sells its own product. What is worth discussing lies elsewhere.
I read the piece three times, listed every information point, and counted. There are seventeen. Fifteen of them are the writer's opinions: "underrated", "surprise weapon", "aggressive", "early initiative", "tricky lines", "unorthodox", "ideal for young players and club players". There is no engine evaluation. No sample game. No rating data. No price. No publication date. The only measurable quantity is sixty minutes.
I am not writing this to tear down a product. I am writing because I have read a great many opening introductions built on exactly this template, and I know what the template does to a club-level reader: it sells them a feeling and lets them pay for it with losses they cannot explain.
The Elephant Gambit is a pawn, called by another name
The board on move two offers a very simple geometric fact. After 1.e4 e5 2.Nf3, Black plays 2...d5 and puts a pawn where White can take it at once. After 3.exd5, Black is a pawn down. There is no complicated contention, no tactical device hiding it. The pawn leaves and does not come back on its own.
The position then splits into four familiar branches. 3...e4 — the Paulsen line — drives the white knight off f3 and opens lanes for Black's pieces. 3...Qxd5 recovers the pawn with the queen, paying with an early queen that becomes a target. 3...Bd6 develops a bishop before the centre is settled. 3...Nf6 develops a knight but leaves the d5 pawn standing alone. Four branches, four ways of spending, all beginning from the same debt.
Mainstream theory and engine practice treat all four the same way: White is considered comfortable, often clearly better, with accurate play. White keeps the pawn, or returns it in a position with a superior structure. That conclusion has been stable for decades. It is not my discovery.
Tactics never lie; readers simply misread them.
So where does the real value sit? It sits in what the introduction calls "surprise", and what I would call a cost recovered in the opponent's time, not in the position.
The refund works like this. Your opponent sits down with twenty minutes on the clock and a memory full of mainstream lines. You play a move that is not in that memory. They must calculate from scratch, and while calculating they spend time, spend confidence, occasionally spend a move. You trade a pawn for those minutes. In three-minute blitz, that is a reasonable trade. In a four-hour classical game, it is a trade that nearly always loses, because the opponent has time to find the truth — and the truth sits on move three.
This is where the introduction quietly contradicts itself. It tells a story about surprise while the headline celebrates "LiveBook" — ChessBase's own online database, the tool any opponent can open to check the win-loss record of 2...d5 in thirty seconds. The publisher sells surprise with one hand and the instrument that destroys surprise with the other. I have tracked opening products for years and have rarely seen the contradiction stand so plainly.
Sixty minutes is a tour, not a repertoire.
A complete Black repertoire for an irregular gambit, done properly, needs several hours of material: four main branches, the sidelines, the lines where White declines the pawn, model games at several levels, and the most important part — what to do when the opponent does not walk into the trap. Sixty minutes cannot hold all of that. It holds a survey: a few model lines, a few pretty traps, a few encouraging words.
Runtime reveals the real audience. Someone buying a sixty-minute opening product is not a player preparing for a major tournament. They are playing for pleasure and want something interesting to carry into an evening game. If that is true, judging the product by asking whether it holds up at 2700 level is asking the wrong question from the start. The right question is whether it is good for a player between 1200 and 1800 Elo.
To that question my answer is yes — with one condition.
A disclaimer written in seven words
Near the end, the writer concedes that, used "with discretion", the student will "rack up the points". I read those words more often than any other line in the piece.
"If used with discretion" is a working disclaimer. It concedes, discreetly but plainly, that the opening is not a daily weapon. It has to be rationed, put away between serious games, taken out as a surprise once against a specific opponent and then put away again. Play it three games running against the same person and the second game is a different game entirely.
And here is the blind spot the introduction never touches: it says nothing about what to do when White declines the pawn. At club level, that is the most common response of all. White may not know the theory, but White knows a simple principle: do not grab a gift before you understand why it is being offered. Spend sixty minutes learning a system built on the assumption that White will take, and then White does not take, and you are standing inside an opening you only half know.
I remember falling into exactly this trap as a young player in Hanoi. I memorised a defensive system the way you memorise a poem — without understanding why each move stood where it stood. When my opponent stepped off the poem, I lost my nerve and lost the game. These days, when I reconstruct those games, I reconstruct them through geometry rather than memory: which piece controls which square, which square is empty, which piece needs to travel through that empty square. One game, two ways of reading it, two outcomes.
Sometimes, to understand the game, you have to stand in silence longer than others can bear.
Part of me wants to defend this product harder. I know the feeling of a club player walking into a game with a set of lines the opponent has never seen. I also know the feeling of being treated as someone who cannot read a mainstream opening. For a player between 1200 and 1800 Elo, many games are decided not by opening knowledge but by which side loses composure first. The Elephant Gambit attacks that composure directly. Measured in that unit, it has real value.
But I cannot defend it with data, because there is no data to defend it with. No sample game, no win rate, no evaluation. An opening product may be sold on inspiration, but to be verified it needs games, and those games are not in the introduction. Martin's involvement is a positive signal — he has a long teaching record. It is also a non-independent one: the same publisher promotes, sells and endorses the product.
People say girls know nothing about tactics. So I write for them to read.
If you are considering this product, here is how I would test it. Open ChessBase's online database or the Lichess opening explorer, type 1.e4 e5 2.Nf3 d5 3.exd5, and look at the win rates at your own rating level. Do not look at the aggregate — it is dominated by games at very high levels. Look at the 1400 to 1800 band, where your opponents actually live. If Black still scores regularly there, the product has a basis. If not, you are buying a feeling.
Then test it in the environment it was designed for: an online blitz session, not a classical game. Record the results. If you win, replay the game and ask whether you won on the position or on your opponent's clock. If you lose, replay it and find where the pawn went.
That is the whole story of the Elephant Gambit, contained in one question every irregular opening has to answer: what are you trading a pawn for, and does it still exist by move fifteen? Andrew Martin's sixty minutes may give you an attractive answer. The board will give you the true one.
