Lesson 3: Rook and Bishop (master the lines) ♟️
Today you are going to learn two pieces that act like "rays" across the board: the rook and the bishop. When you understand these two pieces, chess starts to make sense: straight lines and diagonals.
✅ What you will achieve today
- Know exactly how the rook moves.
- Know exactly how the bishop moves.
- Understand the most important concept: a piece blocks the way.
- Do a mini-practice to "see" attacks and defenses.
1) The Rook: moves in a straight line
The rook is a "straight line" piece. It moves along ranks and files. It is especially strong when there are open files and the board is clearer.
Rook movement: it can move as many squares as you want horizontally or vertically, as long as there are no pieces blocking the way.
Golden Rule: pieces block
If there is a piece in front of the rook, the rook cannot jump over it. It can only capture it if it is an enemy and is directly in its path.
Common mistake: wanting to move the rook "through" a piece. In chess, only the knight jumps (we will see this in Lesson 4).
2) The Bishop: moves diagonally (and always on the same color)
The bishop moves diagonally. There is a very important detail that many people learn late: each bishop always stays on the same color.
Bishop movement: it can move as many squares as you want diagonally, as long as there are no pieces blocking the way.
🎯 Key detail (very easy to remember)
If your bishop starts on a white square, it will live on white squares for the entire game. If it starts on a black square, it will live on black squares for the entire game.
3) Today's Mini-Mission (5 minutes)
This practice is super useful because it teaches you to "see" attacks and defenses on the board.
- Place a rook on d4.
- Place a pawn (any color) on d6 (in front of the rook).
- Question: Can the rook attack the d7 square?
- Answer: No, because the pawn blocks the way.
- Now remove the pawn from d6. Does it attack d7 now?
Answer: Yes, because the line is open. - Repeat the same with a bishop on e4 and a pawn blocking the diagonal (for example on f5).
The bishop moves diagonally and cannot jump over pieces. If a square is occupied, its advance is blocked.
The rook can only move when it is unblocked. It moves in a straight line and cannot jump over pieces.
4) Next Lesson
In Lesson 4, you will learn about the two most "unusual" pieces for beginners:
- The knight (it's the only one that jumps).
- The pawn (it moves one way and captures another).
Note: In this chapter, we are still not using the notebook. The notebook will appear when we start to look at games or sequences of moves later on.
