The Difference Between “Solving Puzzles” and “Training with Puzzles”
There is a fundamental difference between spending 2 hours rapidly clicking through Lichess puzzles and spending 45 minutes working seriously on tactical problems. The first develops superficial pattern recognition. The second develops real calculating ability, which is what you need in a game.
Pattern recognition is useful — it lets you quickly spot a fork or a pin. But below 1800 Elo, the main cause of tactical defeats is not “I didn't see that it was a fork”. It's “I saw the fork but I didn't calculate all of my opponent's replies”. Real tactical training works on that exhaustive calculation.
How Many Puzzles a Day?
The answer depends on your method. If you do 50 puzzles in 30 minutes, looking for the answer fast: limited value. If you do 10 puzzles in 30 minutes, calculating every variation before you click: excellent training. Quality matters more than quantity.
A Method for Mate-in-2 Puzzles
Mate in 2 is the simplest and most fundamental form of tactical puzzle. It develops two skills at once: seeing the weak squares around the enemy king and reverse thinking (starting from the mate you want and working back to the first move).
The solving method
- First identify the direct mates: is there a piece that can give mate immediately? If so, can it be played? If not, what obstacle is preventing the mate?
- Identify the available checks: list every move that gives check on the first move. For each, calculate your opponent's replies and check whether a mate in 1 follows.
- Look for quiet moves: the strong moves in a mate-in-2 don't always give check on the first move. Sometimes the first move creates a mating threat so strong that the opponent has only one reply, and that reply allows a direct mate. These “quiet” moves are the hardest to find.
- Check all the opponent's defences: before declaring a solution, check every possible reply by your opponent to move 1. A single unchecked move can invalidate your solution.
The 8 Fundamental Tactical Themes
Puzzles fall into recurring themes. Knowing these themes doesn't replace calculation, but it directs your search. Here are the 8 themes every club player must master:
| Theme | Description | Pieces involved |
|---|---|---|
| Fork | One piece attacks two enemy pieces at once | Knight (classic), pawn, queen |
| Pin | A piece is immobilised because moving it would expose a more valuable piece | Rook, bishop, queen |
| Discovered attack | A move reveals an attack by a piece standing behind | All pieces |
| Double check | Two pieces give check at the same time — the king must move | A specific discovered attack |
| Absolute pin | A pin against the king — the pinned piece cannot legally move | Rook, bishop, queen |
| Interference | Cutting the line of an enemy piece (rook, queen, bishop) | Varies |
| Deflection/Decoy | Forcing an enemy defending piece to leave its protective square | Often by sacrifice |
| Overloading | An enemy piece performs two defensive duties — force it to abandon one | Often queen or rook |
Advanced Training: Mate-in-3 and Mate-in-4 Puzzles
Once you have mastered mates in 2 (that is, you regularly solve them in under 60 seconds), move on to mates in 3 and 4. These puzzles develop a crucial skill: calculating a tree of variations.
The calculation tree technique
Picture your calculation as a tree in which each branch represents a line of play. The trunk is the current position. Each fork is a possible move. The method:
- Identify the “candidate moves” (usually 2–4 moves that seem relevant)
- For the first candidate, calculate all of the opponent's replies to the first move, and for each, the continuations to a position you can evaluate
- Repeat for the second candidate, and so on
- Don't jump from one branch to another without finishing it — this is the main cause of calculation errors
The Mistake of Premature “Pruning”
“Pruning” means stopping the calculation of a branch because it looks bad. The problem: if your evaluation is wrong, you miss the right continuation. Engines explore far more branches than humans do. To improve, try to check one extra enemy reply in each session.
