MASTER'S TACTICAL CORE
600 Real Games · 600 Key Training Positions · 50 Tactical Themes · 2,400 Training Moves · Stockfish 18 Verification
A comprehensive chess tactics training course by International Master Sergey Germanovich Kolesnyak, developed within the educational framework of the Higher School of Grandmasters and World Champions.
This volume presents 600 carefully selected tactical positions derived from 600 authentic chess games, combining historical chess practice, systematic calculation training, and rigorous Stockfish 18 verification.
The central objective is to develop independent tactical thinking: the ability to recognise critical features of a position, identify tactical opportunities, calculate accurate continuations, and make sound decisions without hints.
Rather than treating chess tactics as a collection of disconnected puzzles, the book connects each training exercise with its original historical game and the practical decisions made by the players.
What This Volume Includes

• 600 authentic historical source games.
• 600 precisely documented training positions.
• 600 seven-half-move training solutions.
• 2,400 training moves by the side being studied.
• 50 tactical themes organised for systematic study.
• 579 historical training solutions retained.
• 21 confirmed Stockfish 18 corrective solutions.
• 20 alternatives verified through repeated comparative engine analysis.
• One additional correction established through a forced mating sequence.
• Complete historical game records preserved as the documentary foundation.
• Engine-verified calculations using a consistent evaluation methodology.
• The three-level educational method: Knowledge → Independent Thinking → Practical Application.
• Integration with the ChessMasterPro training methodology.

50 Tactical Themes — A Systematic Approach to Calculation
The volume explores a broad range of essential tactical mechanisms, including:
Double attacks, knight and pawn forks, pins, skewers, discovered attacks, discovered checks, double checks, deflection, decoys, overloaded pieces, interference, line clearance, intermediate moves, quiet moves, mating nets, sacrifices, pawn breakthroughs, tactical defence, perpetual check, stalemate resources, and forced transitions into favourable endgames.
The exercises are organised by tactical theme, allowing readers to recognise related mechanisms in different practical situations and progressively improve their calculation skills.
Historical Authenticity and Stockfish 18
Every training position is derived from an exact historical chess position.
The original game and the move actually played remain preserved in the book. Stockfish 18 serves as an independent analytical verification instrument rather than a replacement for human chess understanding.
Of the 600 positions, 579 retain their original historical training solutions. In 21 confirmed cases, separate corrective training continuations are provided after rigorous comparative verification.
A corrective solution is admitted only when evidence demonstrates a stable improvement of at least 0.40 pawns for the side to move, or when a forced mating sequence establishes the correction.
This approach preserves historical authenticity while ensuring that the electronic training material follows verified analytical standards.
From Tactical Recognition to Independent Thinking
The educational process follows a structured sequence:
Understand the Position → Identify the Tactical Mechanism → Calculate Independently → Verify the Solution → Apply the Knowledge
Readers are encouraged to analyse each position before revealing the answer, formulate their own calculation tree, and explain the tactical justification behind the chosen continuation.
Every solution contains seven half-moves, including four decisions by the training side and three replies by the opponent.
Knowledge → Thinking → Practice
The course applies the three-level educational methodology of the Higher School of Grandmasters and World Champions.
At the first level, players acquire an understanding of tactical mechanisms through structured study and visual examples.
At the second level, they solve targeted training exercises independently and develop their calculation abilities using the ChessMasterPro platform.
At the third level, acquired knowledge is tested in practical play, followed by analysis, correction, and systematic repetition.
This creates a continuous learning cycle in which mistakes become new opportunities for targeted improvement.
Who This Book Is For
Designed for ambitious club players, chess coaches, advanced students, tournament competitors, and anyone seeking to strengthen practical tactical calculation, this volume provides a structured training system based on authentic chess history and verified analytical solutions.
The objective is not simply to memorise combinations, but to develop the ability to recognise tactical opportunities, calculate accurately, and make independent decisions under competitive conditions.
Study the position. Recognise the pattern. Calculate the variation. Find the move. Apply the knowledge.
