Avoiding 2.c4 to Dodge the 'Theory Tax': IM Valeri Lilov's Six Videos and a Name Out of Place

On Thursday evening I sat in a coffee shop on Nguyen Chi Thanh Street in Da Nang, watching two young players set up a board. White pushed 1.d4. Black answered 1...Nf6. The game slid into a familiar lane: 2.Bg5. Nobody around the table mentioned the Slav, the Semi-Slav, or the main lines I once stayed up nights transcribing. They chose systems. They did not choose theory. The next morning I clicked a link. The headline read: an interview with Timur Turlov. The entire body concerned something else: six instructional videos by IM Valeri Lilov, a Bulgarian coach, for Black against non-critical 1.d4 systems. The name Turlov never appears once in the content. That is the detail I held onto longest, longer than the chess itself. To understand why those six videos exist, look at what club players call the theory tax. After 1.d4 d5, the move 2.c4 opens the Queen's Gambit family. Black can choose 2...e6 for the Queen's Gambit Declined, 2...c6 for the Slav and then the Semi-Slav, or 2...dxc4 for the Queen's Gambit Accepted. Each branch is an enormous body of literature, running dozens of moves deep, with thousands of lines recorded in databases. For a club-level player, the price of learning all of that far exceeds the time available. So they dodge it. Instead of 2.c4 they play 2.Bf4 of the London System, 2.Nf3 followed by e3 and Bd3 of the Colle System, 2.Bg5 of the Trompowsky, or 2.Nc3 with Bg5 of the Richter-Veresov. These are plan-based openings, not memory-based ones. The phenomenon is real and durable at the amateur level. The problem lies in how it was packaged. The article labels this group of players as not very ambitious, a phrasing that mildly insults the exact audience the product targets. On the teaching side, Valeri Lilov is introduced as an International Master. Within FIDE's lifetime title system, International Master is the second-highest rank, below Grandmaster. An IM is a credible reference at club level, though not at the level of elite preparation. The source material supplies no rating, no tournament record, and no sample games. The course's strongest selling point is its promise: a relevant plan for Black against each opening. Six videos, eight or more systems. That ratio already says something about depth. A Grandmaster programme usually devotes an entire course to a single system. Here, each topic most likely receives one compact plan, easy to remember and easy to apply in amateur games. Plan-based openings demand a different kind of memory. Learners do not recall move sequences; they recall structures. But when Black must prepare for eight systems inside six videos, the burden shifts from memorisation to classification. The learner has to work out which system they are in, and that identification is often harder than executing the plan itself. Look at the move orders and the line between marketing and scholarship becomes clearer. The Colle System runs 1.d4 d5 2.Nf3 Nf6 3.e3. The Richter-Veresov runs 1.d4 Nf6 2.Nc3 d5 3.Bg5. The Blackmar-Diemer is 1.d4 d5 2.e4. Those three fit a 1.d4 d5 frame. But the Trompowsky is 1.d4 Nf6 2.Bg5, and the Torre is 1.d4 Nf6 2.Nf3 followed by Bg5. Neither passes through 1...d5. And the Catalan, 1.d4 Nf6 2.c4 e6 3.g3, contains precisely the move 2.c4 that the article says White is avoiding. That looseness reflects a taxonomy built for promotion rather than for editing. I still keep the habit of slowing down broadcast footage to count every stride between the hurdles. With chess I do the same: I lay the moves side by side, read the order, and ask which move must come before which. People talk about speed, but I find time — time to understand an idea, and the time an opponent does not have. When I built the Vén màn tốc độ video series about Nguyen Thi Oanh in 2026, I learned that one sufficiently concrete technical detail can pull an entire larger story up with it. Drawing back the curtain on speed, I met a whole generation running. On the board, that generation runs too, but it runs with moves, and in a very different way. From the sandpit runway to the virtual arena, the homeland of sport has no borders. A 1400-rated player in Da Nang and a 1400-rated player in Sofia face the same question: after 1.d4 Nf6 2.Bg5, what do I do on move twelve with twenty minutes left? A database will not answer for them. It tells you what others played. It does not tell you what to play. That is why courses of this kind still have a place. They do not sell lines. They sell plans. The way a polymath reads a board sits in the same place: reading sequence, rhythm, and the gaps between moves, rather than reading moves in isolation. The counter-intuitive angle sits here. Every technical claim in the article may be right or wrong, and that matters far less than something else: the integrity of the source. The headline names a man who appears in none of the body's information points. Several claims are attributed to no source at all. Every statement favourable to the product comes from the author or from the seller. It could be an editorial error, a portal stitching one article's headline onto another article's body. It could equally be sponsored content, where a financially weighty name sits in the headline to anchor a brand while the body promotes a product. Both roads lead to the same place: a reader clicks for an interview and receives a sales pitch. There is a subtler blind spot. Calling system players unambitious assumes that main-line theory is the only measure of seriousness. Those players are not avoiding study. They allocate their study time differently. In one week, a working amateur can memorise three plans, or read half a chapter on the Semi-Slav. The first choice wins more games. What deserves watching is not any particular set of six videos, nor the identity of the name above the headline. What deserves watching is whether chess instruction keeps the boundary between teaching and selling. When headline and content drift apart, the loser is the beginner, the person who spends money and time looking for a decent plan. What I take back to that coffee shop next Thursday is a question: in your own game, can you state your plan in a single sentence?
