ChessMom returns, but the real story is 9...a5: the line that sidesteps the Bayonet with strategy

I tagged 640 games before I understood the bedroom. In 2026, I was an assistant coach at a small academy in Mymensingh. By day I taught chess; by night I wrote match reports for bdnews24.com. In the Premier League, Police, Navy and Biman teams hired Indian guest grandmasters for their top boards. I did not tag those games by results; I tagged them by pawn structure and endgame type. After building a file of 640 games, the bedroom itself became the board. Since then I never open a piece with a headline, but with a position. The headline says ChessMom is back, promising to support mothers on and off the board. But once the DVD cover is opened, there is no mother inside. There is the Mar del Plata. That branch of the King's Indian Defence where Black plays 7...Nc6 and both wings erupt. White's most fashionable weapon is the Bayonet Attack, 9.b4. This DVD promises to teach 9...a5 against that attack. That gap between headline and content is front-page news for me—not just chess news, but marketing news. Why does the Bayonet Attack feel so threatening? In the King's Indian, Black first gives up the centre and later strikes with...e5. In the Mar del Plata, after 7...Nc6, White roars on the kingside while Black counters on the queenside. White's 9.b4 arrives like a thunderbolt. The move interferes directly with Black's ideas. In the main line 9...Nh5, the game suddenly opens, a long chain of forced moves follows, and computer analysis becomes essential. Anyone who studies this line knows: 9...Nh5 means swimming in a sea of memorisation. This DVD proposes something completely different. With 9...a5 Black announces: I am not playing your war. The move starts a struggle for queenside space, keeps...b5 in the air, and most importantly, avoids the forced stream. According to the producer, this line has very few concrete variations; the positions are sound and strategic. In other words, less memorisation, more understanding. Here I stop. Because next to this claim, there are no numbers. Batumi taught me to read dossiers like weather reports. Working with Bangladesh's support staff at the 43rd Chess Olympiad, I built files on the board-one habits of every opponent. My rule: a claim without numbers is emotion. In the entire analysis of this DVD, there is not a single engine evaluation, no ACPL, no win percentage, no database sample. To me, that is a huge empty square. Comparing the main line 9...Nh5 with 9...a5, one thing is clear: this is not a claim of objective superiority, but of practical comfort. In 9...Nh5 the play is sharp, the calculation is hard, and one mistake can turn the game upside down. In 9...a5, there is no such forced sequence; Black gets time to understand the opponent's plan. For players who lose hours in open, complicated lines, this is indeed a path. But that this path is as strong as the main line is not proven. The producer says objectively the chances are equal, and if Black knows the plans, things might quickly become dangerous for White. I have read that sentence in many repertoire DVDs. There is another claim: computers often do not know how to handle the arising complex strategic positions. That makes me smile. Modern engines play closed King's Indian positions very well. When the academy shut down in 2026, empty halls sent me to online boards for noise. I tagged games from Chess.com blitz marathons and Leonine Chess Club's online events, and I saw that engines do know where to stand in these positions. "Computers do not understand" is no longer a technical observation; it is the language of marketing. I borrowed broadcast grammar until it became a scouting tool. After watching Russia's World Cup coverage in 2026, I changed the way I wrote chess previews. That tool works here too: I will not call 9...a5 new. It is a known sideline. Search the databases and you will see it has been played against the Bayonet before; for a long time it has existed as an alternative to the main line 9...Nh5. So this DVD is probably old theory in a new wrapper. Where does the ChessMom title come from? The headline has no relation to the content. "Supporting mothers" and 9...a5 in the King's Indian do not sit at the same table. My suspicion is that the title belongs to a branding campaign, while the real identity of the DVD is secondary. This is a data-quality problem. A buyer may think this is special material for mothers; in reality, it is a regular repertoire DVD aimed at club to IM level players. The sample grew until the room disappeared. In 2026, watching Tokyo's empty seats and the Euro's condensed graphics, I built a spreadsheet for every game of the National Championship from 2026 to 2026. I saw that after the school circuit died in 2026, participation fell by more than half. Seventeen years, 2,600 rated games, two corporate patrons—that is Bangladesh's chess ceiling. This DVD is not the solution to that structural problem. Teaching a sideline does not produce a grandmaster; a school circuit and a budget do. Still, for those who play Black in the Mar del Plata, 9...a5 is an important practical option. I am not criticising it; I am accounting for evidence. The claim "chances are equal" has no move data beside it, no engine run. Any player who wants to play 9...a5 should verify the line with an engine and check games in their own database. Five minutes of verification is worth more than a five-hundred-taka DVD. For me, the question lies elsewhere. Until this DVD produces trustworthy data against the Bayonet, it remains a teaching tool, not proven theory. ChessMom's return is good news, but mothers will not be on the chessboard—9...a5 will be, under the engine's silent verdict. The real thing to watch is when White's counter-antidote arrives. For those in Bangladesh thinking of buying this DVD, one final word: buy it, but with open eyes. The promise of the headline and the reality of the board are different. However cunning a line may be, the real weapon against the Bayonet is proof, not marketing.
