Dejan Bojkov: Material Imbalances deciphered: The True Value of the Pieces

Review by Prathamesh Mokal

What matters more, the nominal value of pieces or the relative value? Every chess player faces this basic problem of choice, especially during the transition from beginner to intermediate phase. The problem of choice gets more complex during the transition from intermediate to advanced level of play. Grandmaster Bojkov gives some wonderful instructions and guides you in this DVD to help you make a better choice in your game.

Every beginner is taught the nominal value of pieces, for example nine points for the queen, five for the rook and so on. But as you progress further many crucial decisions in your games are based not on the nominal value of pieces, but the relative one. The queen may nominally have one point less than two rooks but with the opponent’s king exposed, its relative power increases substantially. Judging the correct relative value of the pieces in situations with material imbalances is a very complex task which makes even masters falter at times. The only way to get better here is study and practise.

Grandmaster Dejan Bojkov, former Bulgarian Champion and trainer of former Women’s World Champion Antoaneta Stefanova, presents a very interesting mix of classical and modern examples to explain the various subtleties related to a select few material imbalances. The DVD mainly covers the following imbalances - Three Minor Pieces versus Queen, Two Rooks versus Queen; Rook, Minor Piece and Pawn versus Queen; Two Rooks versus three Minor Pieces; Rook versus two Minor Pieces and so on. According to the author he has tried to cover those imbalances which are seen quite often and which are very close to each other. Also they are those imbalances that do not give immediate decisive advantage to any side. He states clearly, that the area of study being vast, it is not possible to cover all imbalances in a five hour DVD. Therefore he recommends DVDs by authors like Mueller and Ziegler to study the other imbalances that are not covered in his DVD.

Bojkov introduces every imbalance in the best way possible, with the most instructive example.

There are a whopping forty-one instructional videos apart from the summary and test positions. With every example comes valuable advice and knowledge of subtle points. For example, at one stage the author apprises the viewers, “Technically speaking, the queen is usually equal to two rooks, although 5+5=10 for the Rooks is greater than 9 for the queen. Usually the queen can hold the fort in the middle game, but as the endgame approaches the rooks become stronger. So naturally with two rooks versus queen you should try to aim for the endgame.”

There is also some interesting trivia in the DVD. For example Bojkov explains: “Did you know that queen versus rook, piece and pawn is also called ‘Lasker compensation’? The reason is that in 1925 it was Lasker who first used it convincingly against Ilyin Zhenevsky. I was given the question in the University exam for going into National Sports Academy. One of the assistants asked me, “What is Lasker compensation?” I was lucky since I had seen the book on Lasker few days ago in which this compensation arose.” A modest recollection!

Here is an instructional extract from the DVD:

At the end, the author presents six test positions in interactive video format. The test positions are clearly related to the material already discussed on the DVD. The supplementary database has a few more examples and studies pertaining to the topic.


The customary interactive training that includes video feedback corresponding to the move you choose.

I don’t know if it is the topic, the author or the examples, but the lessons do not get dry anywhere! I enjoyed the full DVD including the test positions wholeheartedly. There are a couple of amazing studies as well as many complex middle game positions. The last test position was the toughest one for me and I messed it up.

A small extract from the author’s summary of this DVD will put light on its instructional value. Bojkov says, “Three minor pieces versus queen or two minor pieces versus rook usually prevail if the conditions are right, when pieces have time to occupy strong posts or outposts. Then the pieces have a chance to slowly build threats, mostly against the pawns. And then the queen or the rook finds it hard to defend such targets or pawns.

There is no doubt in my mind that if the knowledge from this DVD is firmly entrenched in the viewer’s brain, there will be a substantial increase in the understanding of the game and eventually in the level of play. Although the DVD is classified in the ‘advanced players’ section in the ChessBase Shop it has something useful for all levels of players, except for complete beginners. It is both entertaining and instructional. A must buy!
