Late at night, I reopened a batch of blitz games on my computer. The same script, over and over: White pushes 1.d4, follows with 2.Nf3, then 3.Bf4. Black answers one move at a time — ...d5, ...Nf6, ...e6, ...c5 — with no thread tying those moves together. Fifteen moves in, White has built a structure where every piece has a job, while Black simply waits. I rewound the opening, muted the sound, and watched only the squares change colour with each move. When the stands are empty, you hear the grass crunch underfoot. That is real football. The same holds on a chessboard — strip away the commentary and one thing becomes clear: Black did not lose because White was strong, but because Black did not know what kind of game was being played.
After 1.d4 d5, the move 2.c4 drags both sides into an ancient forest: the Slav, the Semi-Slav, the Queen's Gambit Accepted, the Orthodox Queen's Gambit. This is the densest theoretical region in modern chess, where databases run decades ahead of the players. Plenty of club players choose to step off that road. They do not play 2.c4. They build systems whose first fifteen moves can be played from plans rather than from memorised variations.

It is a fairly crowded family: the London System with Bf4, the Colle System with e3 and Bd3, the Trompowsky with an early Bg5, the Torre Attack with Nf3 and Bg5, the Catalan with g3 and Bg2, the Blackmar-Diemer Gambit with its e4 pawn sacrifice, the Richter-Veresov with Nc3 and Bg5. Different shapes, one intention: refuse the theoretical battle.
Into that exact niche steps IM Valeri Lilov — introduced as a Bulgarian trainer — with a six-video series inside the "Power of Initiative" programme, episode 21, promising Black a practical plan against each of those systems. The product title mentions the Benko Gambit.
Drawing the shape onto the board
Based on my experience tracking these games, most club players lose to these systems not because they lack variations, but because they cannot see the geometry of the position. The London System opens with Nf3, Bf4, e3, c3, Bd3, Nbd2. The subtlety is that the bishop comes out to f4 before e3 closes the diagonal. White builds a pyramid on d4-e3-c3 and parks the bishop outside the pawn chain. Black's counter-plan, therefore, is not to hunt for a brilliant move but to find the right trade at the right moment. ...Bf5 or ...Bg4 to remove the f4 bishop; ...e6 followed by ...Bd6 to offer another trade; ...c5 to strike at the base of d4; and ...Ne4 or ...e5 to occupy the hole. If Black succeeds in trading off the f4 bishop, White's entire attacking scheme evaporates.

The Colle System runs e3, Bd3, Nf3, 0-0, Nbd2, c3. The bishop on d3 — what analysts habitually call the "Colle bishop" — stares straight at h7. Black answers with ...c5, ...b6, ...Bb7, ...Nbd7, ...Qb6 to press against d4, and a well-timed ...e5. The Colle's weakness is tempo: White spends three moves on e3, Bd3 and c3, handing Black freedom in the centre.
The Trompowsky Attack plays Bg5 very early, challenging the f6 knight and disrupting the pawn structure. In exchange, White commits the bishop before knowing what Black will build, may have to retreat it, and if Black knows the ...Ne4 and ...c5 setups, White is the one conceding the centre. The Torre Attack is the quieter version, often transposing into familiar territory.
For a product teaching defence, three facts are worth weighing. First, six videos cover seven systems — on average less than one video each. That is an orientation map, not a complete repertoire. Second, the claim that these systems are "extremely dangerous" arrives with no win rate, no engine evaluation, no figures at all. Third, the Benko Gambit in the title does not arise from 1.d4 d5 at all — it comes from 1.d4 Nf6 2.c4 c5 3.d5 b5, an entirely different road. That name is there to catch searches more than to describe content.
The blind spot sits with the buyer
Tactics never lie; only the reader misreads them. Here, the easiest reader to mislead is the buyer.
The "extremely dangerous" framing is a sales device. Seen plainly, the London System and the Colle System are solid but unambitious — at the top level, the London is often a drawing weapon, and the Colle is almost absent from elite events. The real danger level depends on the quality of Black's preparation, not on the system itself. The product is selling a solution to a problem whose urgency it helped manufacture.
There is another gap around authority. Valeri Lilov is named as a "Bulgarian trainer", but no Elo rating, no tournament record, and no named students appear in the introduction. For club players, IM-level material is appropriate and widespread; for anyone building a repertoire for competitive play, the distance between an IM and a GM is a real distance.
To be fair, the product's structure fits its audience: one system per video, plans rather than variations, exactly what club players need. But take the simplest arithmetic — seven systems divided by six videos — and the depth is unlikely to rise above the introductory level.
What is worth carrying forward
Next time an opponent opens 1.d4 and then 2.Nf3 without 2.c4, resist asking "what is the trap here". Ask instead: which square did White just leave bare? The London exposes the f4 bishop, the Colle exposes the centre, the Trompowsky exposes the bishop's retreat squares. A single move can be the answer to every doubt — and it can also be the question turned back on us, if we stand still long enough to read it. A repertoire is a filter, not a cure. What is worth paying for is not a list of variations, but the ability to see the square before the opponent occupies it.
