It is very important that you have mastered exercises 1-7 before starting on this exercise. For exercises 1-7 visit the chess exercises page.
Without looking at the board, tell all the squares controlled by:
- a knight on c6
- a knight on f3
- a knight on b2
- a knight on c5
- a knight on h7
(adapted by Herman Grooten)
The following thought process which is recommended by Karpov and Mazukevich is used to detect the important features of an arbitrary position in order to devise a plan that conforms to the positional assessment derived by using this thought process.
This thinking process is based on 7 criteria in which the White position is compared with the Black position.
1. What is the material balance?
2. Are there any (direct) threats?
3. How is the safety of both Kings?
4. Pawn structure questions:
a. Where are the open lines and diagonals?
b. Are there many strong squares?
c. Who is controlling the center
d. Who has more space and where on the board do they have it?
5. Which pieces are active and which are not?
Training applications:
Go through the questions out loud while doing middlegame positions based on Stoyko Exercises. The idea is to practice “talking out loud” with the list in front of you so that when you are in real game mode the questions will be asked subconsiously.

It is very important that you have mastered exercises 1-6 before starting on this exercise. For exercises 1-6 visit the chess exercises page.
Without looking at the board, tell all the squares controlled by:
- a knight on c3
- a knight on e2
- a knight on f6
- a knight on d4
White to move
1. Material: White is up a pawn, that is about to Queen. But White cannot defend it.
2. King safety. White’s King is pinned to the light squared bishop. Black’s King is in no immediate danger.
3. Activity: Black’s rook is more active, and his bishop is not pinned like White’s.
4. Pawn structure. White has the better pawn structure on the Kingside, and has a passed pawn on the Qside.
Biggest threat for White is 1…Rxa7 losing the passed pawn and heading into a draw.
Problem is that White cannot defend the pawn with the rook since the rook is lost with either 1.Ra8 or 1.Rc7.
Candidates:
Highlight text for answer:
1. Rxc6+ {the most forcing move} Kxc6 2.a8=Q Rxa8 3.Be4+ {Wins the Black rook due to the skewering of the King and the Rook}
This content was buried in a post for Kotov’s Method for Chess Improvement, and since it is such an important chess improvement tool, I figured I would promote it to its own post.
Stoyko Exercises
from Dan Heisman’s Exercises page
A summary of Stoyko exercise:
1) Find a fairly complicated position
2) Get out a pen/pencil and paper
3) You have unlimited time
4) Write down every (pertinent) line for as deep as you can see, making sure to include an evaluation at the end of the line. This will likely include dozens of lines and several first ply candidate moves. Evaluations can be any type you like:
a) Computer (in pawns, like +.3)
b) MCO/Informant (=, +/=, etc.)
c) English (”White is a little better”)
5) At the end state which move you would play and it’s “best play for both sides” line becomes the PV
6) When you are done, go over each line and its evaluation with a strong player and/or a computer. Look for:
a) Lines/moves you should have analyzed but missed
b) Any errors in visualization (retained images, etc.)
c) Any lines where you stopped analyzing too soon, thus causing a big error in evaluation (quiescence errors)
d) Any large errors in evaluation of any line
e) Whether the above caused you to chose the wrong move
etc.
It is very important that you have mastered exercises 1-5 before starting on this exercise. For exercises 1-5 visit the chess exercises page.
Without looking at the board, tell all the squares controlled by:
- a bishop on b2
- a bishop on b7
- a bishop on a5
- a bishop on h4
- a bishop on d4
- a bishop on c4
For exercises 1-4 visit the chess exercises page.
It is very important that you have mastered exercises 1-4 before starting on this exercise.
Without looking at the board, tell all the squares controlled by:
- a bishop on g2
- a bishop on g7
- a bishop on e5
- a bishop on b7
- a bishop on d2
- a bishop on c5
Previous Exercises:
- Exercise 1
- Exercise 2
- Exercise 3
For exercise 4, using the board look at all of the squares controlled by:
- the f1-bishop developed to e2 (place only this bishop on the board)
- the f1-bishop developed to d3, c4, b5
- the f8-bishop developed on e7, d6, c5, b4
- all remaining bishops as above
Then, without the use of the board repeat the exercise again visualizing the squares controlled by the bishops above.
Perform this exercise for 2 sessions or until you feel comfortable.
After mastering exercise 1 and exercise 2 you are ready to move on to the third chess board visualization exercise.
Using the board look at all of the squares controlled by:
- a knight on c3
- a knight on f3
- a knight on c6
- a knight on f6
Then, without the use of the board repeat the exercise again visualizing the squares controlled by the knight on f3, c6 and f6.
Perform this exercise for two sessions or until you feel comfortable. You should also repeat exercise #2 until you are extremely comfortable performing it.
Remember it is important to build upon fundamentals, and exercise # 2 is an important building block in developing chess visualization skills.
