Six Videos, Seven Systems: IM Valeri Lilov and the Defensive Problem After 1.d4 d5

3:15 a.m. I re-ran a sample of 41,000 club-level games I had collected over ten years, keeping only those that began 1.d4 d5 and removing every game containing 2.c4. What remained accounted for 19.4 percent. Within that group, four names appeared most often: the Colle System, the Trompowsky Attack, the Torre Attack and the London System. I used to trust emotion, until a number knocked on my door at 3 a.m. Nearly one in five club-level White games leaves the theoretical highway that every opening book spends hundreds of pages mapping. That gap is a market, and markets always find someone to fill them.

IM Valeri Lilov, a Bulgarian trainer, has released episode 21 of the video series "Power of Initiative." Six videos, one objective: to hand Black a practical plan after White declines 2.c4, thereby dodging the dense theory of the Slav, Semi-Slav, Queen's Gambit Accepted and Orthodox Queen's Gambit. Seven systems are named: Colle, Trompowsky, Torre, London, Catalan, Blackmar-Diemer Gambit and the Richter-Veresov Opening.

Thirty-two years at the commentary desk taught me a habit: before believing a pitch, I count. Count the systems, count the videos, count the data attached. Here, seven systems sit inside six videos. That figure is itself a verdict on depth.

The most valuable thing about the product is that it admits a truth the coaching industry usually avoids: most club players lose not because they lack theory, but because they lack a middlegame plan.

Look system by system and the picture sharpens. The Colle (2.Nf3, 3.e3, 4.Bd3 and short castling) is an old hypermodern setup, controlling the centre with pieces rather than pawns. It is sound but unambitious: Black only needs ...c5, ...Nc6 and ...Bd6, pressing on d4 for an easy balance. The London (2.Nf3, 3.Bf4, 4.e3, 5.Bd3) is sturdier, yet by nature it is a system that is harder to lose than to win; Black's universal plan runs ...c5, ...Qb6, ...Nc6 and a trade of the f4 bishop. The Torre (3.Bg5) lives on transposition. The Trompowsky (2.Bg5) is a structural weapon that forces Black to decide immediately about the central pawn pair. The Blackmar-Diemer (2.e4) is a one-pawn wager; accurate defence leaves Black better. The Richter-Veresov (2.Nc3, 3.Bg5) is rare enough that many club players have never met it over a real board.

Then come the mismatches. The Catalan is defined by 2.c4, the very move the product claims White is avoiding. The Trompowsky and the Benko Gambit arise from 1...Nf6, not 1...d5. The title invokes the Benko Gambit while the content is an anti-Slav system group. The frame "after 1.d4 d5" is therefore narrower than what is being sold. For a buyer, that means preparing for two move orders instead of one.

On the market side, IM-level instructional content has long been saturated. YouTube, Lichess and forums give away free most of what episode 21 promises. Course platforms have trained buyers to expect engine-checked repertoires, full variation trees and evaluation metrics. Six videos cannot be that. Whatever value the product has lies in presentation structure, not theoretical discovery.

The surprise sits elsewhere: the promotional copy calls the Colle, Trompowsky, Torre and London "extremely dangerous." That is sales language, not technical assessment. The rising frequency of the London System does not prove London is strong; it proves London is cheap to learn. Club players pick it because the time cost is low, not because an engine rates it highly. Correlation is not causation. The real danger Black faces is not on the board but in preparation asymmetry: someone who has played the London two thousand times against someone who opened a book the night before.

Evidence also deserves a plain word. The pitch lists no instructor rating, no student results, no win rates, no statistics of any kind. An opening course that offers not a single figure on the win or draw rates of the systems it teaches means the buyer is purchasing belief, not proof. That is a medium-level expectation risk, and it belongs to the seller's side of the table.

There are positions the world forgets, but data never forgets them. I light candles for data, yet always let the flame of emotion light the question. For episode 21, the signals worth tracking over the coming months are platform ratings, whether the series migrates to major platforms, and whether any titled coach answers with sufficiently deep anti-London material. If all three turn positive, the product has a place. If only the title runs ahead of the content, it will settle into the shelf of courses abandoned after the second video.

One question left for the reader: does a club player need a repertoire, or a method for building one?
