Svitlana's Smart Moves: An Anti-Bayonet Weapon for the King's Indian, Sourced from the Olympiad

Berlin: Every few months the chess opening-theory market produces a product claiming to have found a reliable counter to a popular White set-up. The latest instalment of the ‘Svitlana’s Smart Moves’ series belongs to exactly that category, and its target is White’s most fashionable weapon in the King’s Indian Defence, Mar del Plata variation: the Bayonet Attack, 9.b4.

As described, the product is a video-based opening repertoire built around model games from the Olympiad. The central recommendation is unambiguous: against 9.b4, Black should play 9...a5 rather than the mainstream 9...Nh5. The argument runs that after 9...Nh5 the game enters a forcing, calculation-heavy sequence dominated by engines, whereas 9...a5 steers Black into strategic, slow, long-range positions — the kind of terrain where human judgement matters more than memorised lines.

The technical background

The Mar del Plata is one of chess’s sharpest two-front systems: White expands on the queenside while Black storms the kingside. The Bayonet (9.b4) has become White’s main modern weapon over the past two decades, aimed at seizing queenside space to blunt Black’s kingside attack. Black has two principal answers: 9...Nh5, the theoretical main line with forcing sequences involving ...f5 and ...Nf4, and 9...a5, a rarer, more strategic alternative.

One clarification is necessary, because the product’s title calls this the ‘King’s Indian Attack’. Technically the King’s Indian Attack is a separate system built on 1.Nf3, g3, Bg2 and d3. What is discussed here is the King’s Indian Defence, Mar del Plata (1.d4 Nf6 2.c4 g6 ... 6.Be2 e5 7.0-0 Nc6). That is not a trivial distinction: in a search-driven market, the terminology error can attract the wrong buyers and confuse the right ones.

The gap between claim and evidence

Most importantly, every technical claim in the product traces back to marketing copy rather than to independent review or database output. No engine evaluation is given, no game counts, no results percentages, no named model games. The paired assertions — ‘objectively equal’ and ‘dangerous for White’ — are a familiar device in opening literature: they calm the buyer’s fear of a refuted line while simultaneously promising practical upside. Both can be true at once, but the material offers no evidence for either.

Likewise, the claim that ‘computers do not understand these positions’ is the weakest technical link and is now dated. Since the adoption of NNUE-based evaluation from 2026, engines have improved substantially in closed, manoeuvring King’s Indian structures; the trope that engines misjudge locked positions belongs largely to the 2026–2026 era. The article even contradicts itself within a paragraph: it says computers struggle here, yet concedes that after 9...Nh5 ‘computer analysis becomes important again’ — implicitly accepting that engine mastery is the norm and that 9...a5 is the escape from it.

Scope: one branch of a large tree

The most practical limitation is that the product addresses exactly one White branch, 9.b4. In the Mar del Plata, White retains fully independent and still popular options on move nine — 9.Ne1 and 9.Nd2 — plus earlier deviations such as 8.Be3 and 8.Re1. A Black player adopting the Mar del Plata therefore still needs separate answers to all of those. The product is not flawed in itself; the flaw lies in the perception that ‘an antidote to the Bayonet’ equals ‘a complete Mar del Plata repertoire’.

Who it is for

The target segment is in fact well defined: players who reason rather than memorise. That is a genuine and underserved category, since the market is crowded with memorisation-heavy repertoires. It is the product’s most honest strength — audience fit rather than novelty. Notably absent, however, are the presenter’s name, title, rating, or record of having played 9...a5 in serious classical games. For a repertoire product, that is a real credibility gap.

The Olympiad branding

Using Olympiad games as model material is sound in principle: deep fields, high stakes, fully public game scores. But there is a selection bias — in team matches a draw is often sufficient, producing less critical, more result-oriented play. A repertoire built primarily on team-event games should be cross-checked against individual elite events. Moreover, no game, round, player or year is cited anywhere: the Olympiad functions here as decoration, not as analysis.

The competitive landscape

The product occupies a narrow but defensible niche: it does not compete with complete King’s Indian repertoires but seeks to complement them at one busy node. Its commercial logic depends on how often the Bayonet actually appears in the buyer’s practice. The structural threat is format — static DVD and video series are being displaced by subscription-based, continuously updated, database-linked repertoires, and a single-line product has a short relevance half-life. If the line becomes popular at rating level, White players will prepare specifically against it, eroding the ‘few concrete lines’ advantage.

The expectation gap — the most under-priced risk

There is a subtle contradiction. The product promises fewer forcing lines, hence less calculation and more strategy. Yet the same material states that such positions demand long-term planning and tactical alertness. In practice, strategy-heavy, non-forcing positions demand more judgement from weaker players, not less — under time pressure that is precisely where club-level players haemorrhage advantage. Marketing that promises ease and delivers difficulty is the commonest source of backlash in niche products.

Risk and conclusion

Overall risk is low-to-medium. There is no safety, integrity or governance exposure; competitively it is teaching material, not in-play assistance, so anti-cheating rules are not implicated. The genuine risks are epistemic and commercial: unsupported technical claims, a narrow scope easily mistaken for a complete solution, and the ordinary decay rate of static opening advice. A second, less discussed risk: 9...a5 is not a novelty — it has appeared in practice before, so the product’s value lies in consolidation and explanation, not discovery.

The verdict: a low-stakes, technically plausible but evidence-free product whose real strength is audience fit, not theory. Players who already own a complete King’s Indian repertoire and want a structured, comprehensible option against the Bayonet may find it a useful supplement. But before adopting it in serious play, 9...a5 must be independently verified against a current engine and a live database. The title’s ‘King’s Indian Attack’ wording should also be corrected, since it misdescribes the product’s subject.
