81 problems, grouped by attacking pieces.
Unlike basic mates, the key move is often a sacrifice. Not a gift — you give a piece to open a line, block a rescue, or keep the attack from breaking.
Study this after you know basic mates. Here you practise one question: after the sacrifice, can I still mate?
- Tell a sound sacrifice from a losing one
- Calculate both branches: they take, and they refuse
- See when a sacrifice opens a line, blocks a rescue, or buys time to attack
- In real games, sacrifice only after you have calculated — not because the book likes sacrifices
Don’t give a piece yet. Look at the whole board:
① Which piece would you give? What do you lose?
② What do you gain — a line, a blocked rescue, or a check that stays on?
③ If you don’t sacrifice, does the attack break?
Sacrifice only when you can answer: without it, there is no mate.
Every sacrifice has two sides:
① If they take it, can you still check / mate?
② If they refuse, is the offer a feint that forces them elsewhere?
③ After the sacrifice, which piece leads, which piece helps?
If you only see “give a piece, then check” and skip their defence — the problem is not done.
The book is ordered by piece combo, not by mate length. Go in order:
- Chariot + pawn, chariot + horse — few pieces, the idea of the sacrifice is clear
- Chariot + cannon, then with a pawn — sacrifice to open a cannon line or build the net
- Chariot + horse + cannon — the main part (37 problems). Don’t rush
- Chariot + horse + cannon + pawn — last
In each chapter: understand a few kinds of sacrifice. You need not memorise every move.
1. Calculate first. Open the line only when truly stuck.
2. Each time you sacrifice, ask: if they take, what is left? If they don’t?
3. When done, retell: which piece, for what, and why refusing the sacrifice kills the idea.
81 problems is not many. A few you understand beat finishing the book on autopilot.
