5 Chess Tactics Every Player Should Know: Forks, Pins, Skewers & More

Grandmaster Chess Editorial Team

Below roughly 1600 rating, most games aren't decided by deep strategic understanding — they're decided by who spots (or misses) a tactic first. Learning to recognize these five patterns will win and save you more games than any opening theory.

1. The fork

A fork is a single piece attacking two or more enemy pieces at once, forcing your opponent to lose material because they can only save one. Knights are especially dangerous forkers because of their unusual movement — a knight fork on a king and queen (a "royal fork") is often decisive.

How to spot it: Before every move, ask whether the piece you're about to move — or any piece already on the board — attacks two valuable enemy pieces simultaneously.

2. The pin

A pin happens when a piece can't move (or shouldn't move) because doing so would expose a more valuable piece behind it to attack. An absolute pin involves the king — the pinned piece legally cannot move at all. A relative pin involves any other piece — it technically can move, but doing so loses material.

How to spot it: Look for enemy pieces lined up on the same rank, file, or diagonal, with your bishop, rook, or queen able to attack along that same line.

3. The skewer

A skewer is the reverse of a pin: you attack a valuable piece that must move, exposing a less valuable piece behind it to capture. The classic example is attacking a king with a rook or bishop along a line, forcing the king to move and revealing a piece — often a rook or queen — that can then be captured.

How to spot it: Same setup as a pin (pieces lined up on a rank, file, or diagonal), but check which piece is more valuable — if the front piece is worth more, it's a skewer, not a pin.

4. The discovered attack

A discovered attack happens when you move one piece out of the way, revealing an attack from a different piece behind it. It's powerful because the piece you moved can also make its own threat — you effectively get two attacks in one move. A discovered check is the most dangerous version: moving a piece out of the way to reveal check from another piece, while the moved piece is also free to capture something.

How to spot it: Look at your own pieces that are blocking a rook, bishop, or queen's line toward an enemy king or valuable piece — moving the blocker can create the discovery.

5. The double attack

A double attack is a broader category: any single move that creates two simultaneous threats the opponent can't both address. Forks are a type of double attack, but the pattern also shows up with pawns (attacking two pieces on adjacent diagonals) and queens (threatening both a piece and checkmate at once).

How to spot it: After making a candidate move, count how many real threats it creates. If it's only one, look for an alternative that creates two.

How to train tactical vision

  • Solve puzzles daily, even just 10–15 minutes. Tactical pattern recognition is a trained skill, not raw talent.
  • Play against AI at a level slightly above comfortable, since it will punish missed tactics more consistently than a weaker opponent. Try the Intermediate or Advanced AI once forks and pins feel natural against Basic.
  • Review your own games specifically looking for missed tactics — both ones you missed for yourself and ones your opponent missed against you.

Frequently asked questions

What's the difference between a pin and a skewer? In a pin, the more valuable piece is behind the pinned piece. In a skewer, the more valuable piece is in front and forced to move, exposing the piece behind it.

Are forks always with knights? No. Any piece can fork — queens and pawns fork frequently too — but knights are especially effective because of their unique jumping movement, which is harder to anticipate.

How do I get better at spotting tactics quickly? Consistent, repeated puzzle practice is the single most effective method. Pattern recognition improves with volume more than with theory study.

Put these patterns to the test in a live game — play the AI or try local pass-and-play and watch for these five shapes on the board.
