A rook takes a loose bishop
Try first: Is the bishop protected?
Rxa6
Capturing piece: White rook on a3
Target: Black bishop on a6
The bishop has no defender. The rook can take it without losing the rook.
Think before you take: protect your pieces and choose captures that pay off.
A capture takes an opponent’s piece. A safe capture is one that follows the rules, keeps your king safe, and does not give away more material than it gains in an immediate exchange. A piece that nobody protects is called hanging (or loose).
| Piece | Pawn | Knight | Bishop | Rook | Queen |
|---|---|---|---|---|---|
| Approximate points | 1 | 3 | 3 | 5 | 9 |
The king has no material point value: you must never make a move that leaves your king in check. Piece points are a quick guide, not a complete rule for every chess position.
Try first: Is the bishop protected?
Rxa6
Capturing piece: White rook on a3
Target: Black bishop on a6
The bishop has no defender. The rook can take it without losing the rook.
Try first: Can a knight take a bigger piece?
Nxe5
Capturing piece: White knight on f3
Target: Black rook on e5
Knights jump over squares. No black piece can recapture the knight on e5.
Try first: Follow the open diagonal.
Bxf4
Capturing piece: White bishop on c1
Target: Black knight on f4
The c1–d2–e3–f4 diagonal is clear, and the knight is undefended.
Try first: Which way can this pawn capture?
dxe5
Capturing piece: White pawn on d4
Target: Black bishop on e5
Pawns capture diagonally. The bishop is undefended, so the pawn wins three points of material.
Try first: Which white piece is loose?
Rxb4
Capturing piece: Black rook on b7
Target: White bishop on b4
The b-file is clear and no white piece protects b4. Notice that Black is shown at the bottom.
Try first: What happens after the pawn recaptures?
Rxd6
Capturing piece: White rook on d1
Target: Black queen on d6
Black can recapture the rook with the c7-pawn. White wins a queen (9) for a rook (5): a four-point material gain.
Opponent’s reply: cxd6.
Try first: Who guards e5?
Bxe5
Capturing piece: White bishop on b2
Target: Black knight on e5
Black’s f6-pawn can recapture the bishop. Each side loses a three-point piece: an equal exchange, not a free knight.
Opponent’s reply: fxe5.
Try first: Is the pawn on d5 truly free?
exd5
Capturing piece: White pawn on e4
Target: Black pawn on d5
Black can recapture with the c6-pawn. Both sides lose one pawn, so it is an equal material trade.
Opponent’s reply: cxd5.
Try first: Where can the black knight land?
Nxd2
Capturing piece: Black knight on e4
Target: White rook on d2
The knight jumps to d2 and captures a five-point rook. No white piece can immediately take it back.
Try first: There are two captures. Which one is safe?
Nxh5
Capturing piece: White knight on f4
Target: Black bishop on h5
Nxh5 wins an undefended bishop. Qxd5? looks tempting, but the c6-pawn guards d5 and can take the queen.
Tempting mistake: Qxd5? cxd5 would lose the queen for a pawn.
Key message: Free capture = gain material without a recapture. Equal trade = win and lose equal value. Favorable exchange = win more value than you lose.
Read the board before opening hints or answers. For an exchange, count the points won and lost.

Compare the value of the bishop and rook. Can Black’s king legally take back?
Correct move: Bxg7.
Bxg7 takes a rook (5). Black can reply ...Kxg7, but the bishop costs only 3, so White gains two points of material. Expected recapture: Kxg7.
| Time | What to do |
|---|---|
| 0–7 min | Quick recap: legal captures, pawn diagonals, kings cannot move into check. |
| 7–15 min | Introduce hanging pieces, 1–3–3–5–9 values, LOOK → CHECK → COUNT. |
| 15–31 min | Model E1–E6 on boards; ask students to predict the recapture. Scan E7–E10 as short group challenges. |
| 31–49 min | Students solve P1–P8 in pairs or independently; P9–P10 for quick finishers / homework. |
| 49–57 min | Mini-game: play from a normal chess starting position; students must say “who guards it?” before every capture. |
| 57–60 min | Ask 2–3 exit questions; assign remaining puzzles as homework. |
Puzzles 9–10 are extensions, not essential for finishing the 60-minute class. The file includes all 10 for follow-up practice.
Demonstration: Point to the target, trace the capture, then give Black or White the next move. Ask, “Can anyone take it back?” Draw attention to the yellow origin/target highlights and the orange move arrow in the worked examples.
Important distinction: “Protected” does not always mean “do not capture.” Winning a queen with a rook is favorable even if a pawn recaptures. Equal bishop-for-knight trades are fine but are not a material win.
Coaching warning: A king never gets a material score. Real games also involve checks, mates, and tactics; piece-counting alone does not guarantee a good move.
