Calculation & Visualization Training

A structured training course in calculating forcing lines and visualizing positions without moving the pieces. The exercises start short and grow longer and harder across the course, and every one comes with a worked solution that shows the full line and the replies that had to be checked.

What the course covers

The workbook is organized into the parts below. Each part explains its ideas first, shows them in annotated examples, and then gives training positions with worked solutions.

  1. How to calculate

    A simple method for working through variations: list candidate moves, start with forcing moves, check every reply, and assess the final position.

  2. Visualization basics

    Exercises in seeing the board without moving pieces: square colors, diagonals, knight routes, and following short sequences in your head.

  3. Short forcing lines

    Sequences of checks, captures and threats a few moves deep, where every reply has to be found and answered.

  4. Longer calculations

    Positions that need deeper and wider calculation, including quiet moves in the middle of a forcing line and defensive resources that are easy to miss.

  5. Holding the position in your head

    Exercises that give a position and a sequence of moves in writing, and ask you to assess the final position without setting it up on a board.

  6. Mixed training sets

    A final run of exercises that mixes every type, arranged in increasing difficulty, each with a fully worked solution.

Preview of an explanation page: Forcing moves firstA workbook page from the explanations. When you calculate, look at checks, then captures, then threats. Forcing moves limit the opponent’s replies, which keeps the number of lines small enough to work through accurately. Key idea: For every forcing move, list all of the opponent’s legal replies before going deeper, not just the obvious one. At the end of a line, stop and look at the final position again before you decide it is good.FIANCHO CHESSCALCULATION TRAININGEXPLANATIONForcing moves firstWhen you calculate, look at checks, thencaptures, then threats.

Who it’s for

  • Players who see the right ideas but lose track of the position a few moves into a line.
  • Players who want structured, progressive exercises instead of random puzzles.
  • Players who are comfortable with the basic tactical patterns and want to go further.

Who it isn’t for

  • Beginners still learning the basic tactical patterns. Tactics Fundamentals comes first.
  • Players who want quick puzzles to solve on screen. These exercises are meant for slow, careful work.
  • Anyone looking for video lessons or personal feedback. This is a self-study workbook.
