Lesson 3 - Pieces' Value, Attack and Threat: Solutions To Exercises

Below are the solutions to the exercises of this lesson.

Questions

1.
What is the relative value of:
a) a bishop? 3
b) a rook? 5
c) a pawn? 1
d) a Queen? 9
e) a knight? 3
   
2.
In a material perspective, is it a good move to capture:
a) a bishop for a rook? No
b) a knight and a pawn for a bishop? Yes
c) two bishops for a knight and a rook? No
d) two rooks for a Queen? Yes
e) a rook and two pawns for a knight and a bishop? Yes
   
3. Using this diagram, give the name of the squares where white pieces are attacked: c3, d4 et g5
Which white pieces are attacked?
   
4. Using this diagram, give the name of the squares where black pieces are threatened:c5, e5 et d8
The pawn on e5 is threatened since White is attacking it 2 times (with the pawn on d4 and the knight on f3) and it is protected only 1 time (by the knight on c6).
Which black pieces are threatened?
   
For questions 5 to 9, you must find the threatened piece and indicate the method you have to use to eliminate the threat.  To identify the method, use the following letters:
a) moving   b) blocking   c) capture the attacker   d) protect the threatened piece
 
5.
Diagramme pour la question 5

White to move:
a) Which square the threatened piece is occupying? h1

b) Which method must be used? b (blocking)

c) If the method is "moving", indicate the square on which the piece must be moved.  Otherwise, indicate the starting square corresponding to the piece used for blocking, capturing or protecting: White can block by moving the d4 pawn to d5. He can also move the f2 pawn or the g1 knight f2 to f3.
Note that White cannot block by moving their f1 bishop to g2 since Black will then be able to capture it and the threat will still exist and unstoppable (ending up loosing their bishop and rook for free...). Same situation for the e2 pawn: if it moves to e4 to block the path, Black could capture the pawn with the c6 knight, White will then capture the knight back with their own knight on c3 and finalle the b7 bishop will capture the white knight renewing the threat on the h1 rook. Black would gain 1 extra pawn in this exchange.

Diagramme pour la question 6

Black to move:
a) Which square the threatened piece is occupying? f6

b) Which method must be used? a (moving)

c) If the method is "moving", indicate the square on which the piece must be moved.  Otherwise, indicate the starting square corresponding to the piece used for blocking, capturing or protecting: moving the piece on h5, e4 or e8

   
7.
Diagramme pour la question 7

White to move:
a) Which square the threatened piece is occupying? g2

b) Which method must be used? c (capture), b (blocking) or d (protecting)

c) If the method is "moving", indicate the square on which the piece must be moved.  Otherwise, indicate the starting square corresponding to the piece used for blocking, capturing or protecting: protecting their bishop by moving the Queen to e2 or moving their King to f1 or f2.

Or: capture the attacking piece with the bishop on g2 or the knight on c3.
The threatened piece is not required to stay passive and it can capture the attacking piece...

Or: blocking the threat by moving the g1 knight to f3.
This solution is not recommended though as it will require the knight staying on the f3 square otherwise the bishop on g2 would be vulnerable (the knight is "pinned"). White would then have a less dynamic position than Black. In order to free up their knight, White would need to move their rook from h1 to g1 on his next move inorder to protect their bishop and allow the knight to get out of the pin..

Diagramme pour la question 8

White to move:
a) Which square the threatened piece is occupying? d7

b) Which method must be used? d (protecting)

c) If the method is "moving", indicate the square on which the piece must be moved.  Otherwise, indicate the starting square corresponding to the piece used for blocking, capturing or protecting: moving the knight to the b6 square
Note that the knight cannot go on the e5 to protect the pawn since it would get captured by the black knight sitting on c6...

 
9.
White to move:
a) Which square the threatened piece is occupying? e5

b) Which method must be used? a (moving)

c) If the method is "moving", indicate the square on which the piece must be moved.  Otherwise, indicate the starting square corresponding to the piece used for blocking, capturing or protecting: moving on the g6 or f3 squares
