GM Adrian Mikhalchishin is a well-known figure in coaching circles, with many years of experience as the author of numerous ChessBase publications and as a coach and second to famous players. In his ChessBase series "Master Your Technique", he focuses on various aspects of converting positions through sound technique.
In the third volume, he covers the following topics:

While the tactical section covers motifs such as cross-pins and backward moves, the chapters on endgame technique and sacrificing for activity deal with situations in which things become concrete and there is no turning back. When a position requires dynamic play in order to convert an advantage, or precise knowledge of theoretical endgames to assess whether a winning idea will work, these chapters are exactly the right place to look.
For this review, however, I would like to focus on the chapter on heavy pieces.

As Mikhalchishin notes in his introductory text, rooks and queens are powerful pieces – but only when they work together. This section of the course therefore focuses on coordinating the major pieces in order to exploit their strategic potential and to assess and plan how an advantage can be converted.
The concepts Mikhalchishin uses for this purpose are "Control the Open File", "Infiltrate the 7th Rank", "Attack with Heavy Pieces", "Play Slow", "Queen Endgame", "Exploiting Weaknesses" and "Support the Passed Pawn".

The chapter about the heavy pieces
In keeping with Markos’ article in ChessBase Magazine #231 on evaluating open files according to their "length" (see review), I particularly like the choice of games here and the motifs involved in the fight for the open file. To illustrate this, I would like to present the game Shirov–Hou Yifan from the 2013 FIDE World Cup in Tromsø, supplemented by textual annotations:
As can be seen, some of the analyses are quite extensive. This is one of the strengths of the course. You are presented with a wealth of ideas that you can incorporate into your own studies. One minor drawback, however, is that some of the analyses contain errors and either have not been checked or have been taken from outdated sources without critical review.
Conclusion
Overall, I like the course. As in the previous volumes, it presents and explores a wide range of ideas. Although the way the course is presented – particularly the explanations and pacing – could still be improved to appeal to a broader audience, the many game examples nevertheless offer plenty of instructive material for training and studying various aspects of practical technique.
Overall Rating: ★★★★ 4/5
Highly recommended!
