A house of cards collapses. Through the lenses of my glasses rises a scene from 2026 — a board in Baghdad, me a teenager, hand trembling as I reach for a knight. Today, sitting in this room in Saint Petersburg, I watch a DVD screen: Black plays 9...a5, and suddenly I realize — this move isn't new. Familiar, yet new. Because this is the move every club player once found themselves, then forgot.

First, the context. King's Indian Defense (KID) — 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 — its core philosophy is ceding the center, then striking back with pieces. 7...Nc6 begins the Mar del Plata Variation, where White storms the kingside while Black pushes pawns on the queenside. The move 9.b4 — known as the 'Bayonet Attack' — is White thrusting a bayonet, tearing apart Black's ...b5 queenside restructuring. Black's main-line reply is 9...Nh5, where the position opens, forced tactics begin, and every move must be engine-perfect.

This DVD's central proposition — 9...a5 instead of 9...Nh5. The move looks harmless, almost polite. In my thirty years of club life, I've played it myself at least seven times, and every time the opponent's eyebrow furrowed — 'What's that?' The question itself is the point. Because 9...a5 isn't a main line, it's a peripheral melody. But what this DVD argues runs deeper: in the engine era, where every main line must be memorized to move 31, this peripheral melody is the escape route. The move builds ...a4, ...b5 plans on the queenside without destabilizing the board. An IM friend from Estonia once told me — 'I can't keep rhythm with engine memorization anymore. I want to play like a human.' This DVD's actual customer is him, not a Grandmaster.

The DVD's central claim is that objectively chances are equal in this line, but if White doesn't know Black's plans, things can quickly become dangerous. That's exactly the problem. The word 'equal' here is a marketing device — no engine evaluation exists in any information point of the Stage-1 analysis, no game database, no sample games. Only language, and the magic of language. In my boyhood I heard on my father's radio — 'This player is the best.' Evidence? Nobody asked. Now in the DVD market, the same sermon, only the packaging has changed.

The claim that 'computers often do not know how to handle these complex strategic positions' is a soft lie in journalistic terms. Modern Stockfish or Leela play these closed positions better than humans, just slightly differently — which is hard for a club player to digest. This very difference is the thorn in the DVD's marketing.

So where is this product's actual value? I'd say — its informational value is limited, but pedagogically it has a legitimacy. It's the work of an author who perhaps grasped this: Grandmasters don't win with this line, but IM-club level Black players survive with it. A professional strategy-preparation junkie spending six hours daily analyzing ...Nh5 — this silent 9...a5 move returns a fraction of that time. Time is a human's real asset.

But there's a name-and-subject mismatch here. The title says 'ChessMom returns: Supporting mothers on and off the board' — but the inner content is entirely KID repertoire. The question arises: is this title part of the same product, or mis-packaging? From Saint Petersburg, I cannot sit in a Dhaka press box and answer this. The reason is simple — this article has no source attribution, no 'Source' written anywhere in any information point. It's a single-source, commercially motivated product introduction. And writing on such material, I follow one rule: information that can't be verified doesn't enter my sentences.

One thing I've learned in my thirty-three-year career — when someone says 'this is a new system,' an old theory hides behind it. 9...a5 isn't new. This move is a known peripheral melody against the Bayonet Attack in KID. The rat-race rule is — when the main line becomes over-analyzed, sideline returns in new packaging. This DVD is part of that cyclical history. For club players drowning in the vast theory-ocean of 9...Nh5, 9...a5 is a floating plank of wood — convenient, but if the tide shifts, perhaps another straw needs to be found.

For me, the question here isn't ended, nor begun. Gazing through Moscow's cold window, I think — is this DVD's creator truly like that patient person who verifies every peripheral melody hour after hour in club darkness? Or is he an accountant surviving on market scent, who knows — the correct title doesn't sell, and the wrong title stirs the buyer? Until I independently run 9...a5 through an engine, the answer to this question remains unanswered in my notebook. The board never lies; humans do.

Two boards, one era, and the quiet accounting of surviving in chess.
