Chess Tactics: Forks, Pins, Skewers and More

Strategy is the long-term plan; tactics are the short, forcing sequences that win material or deliver checkmate right now. Most games below club level are decided by tactics, not strategy — so this is where beginners improve fastest.

Why tactics matter more than openings early on

You don't need a deep opening repertoire to win games as a beginner — you need to stop dropping pieces to simple tactics, and start spotting them yourself. Every tactic on this page follows the same underlying idea: find a move that creates two threats at once, so the opponent can only deal with one of them.

The fork

A single piece attacks two (or more) enemy pieces at the same time. The opponent can only save one, so you win the other. Knight forks are especially dangerous because knights attack awkward squares that are easy to overlook — a knight landing on a square that attacks both the king and the queen is one of the most common ways games are decided at club level.

The pin

A piece is pinned when it cannot move (or shouldn't) because doing so would expose a more valuable piece behind it to attack. There are two kinds:

• Absolute pin — the piece behind is the king. Moving the pinned piece would be an illegal move, since it would leave the king in check.
• Relative pin — the piece behind is not the king (often the queen). Moving the pinned piece is legal, but usually loses material, so it's pinned in practice even though not by the rules.

Pins are usually created with a bishop, rook, or queen attacking along a line — and they're often the setup move for a bigger tactic, not the whole tactic by themselves.

The skewer

The reverse of a pin: a more valuable piece is attacked first, and when it moves out of the way, a less valuable piece behind it is captured. A common pattern is a rook or bishop attacking a king, forcing it to move, and winning the piece that was hiding behind it.

Discovered attack

Moving one piece out of the way reveals an attack from a different piece behind it. Because the moving piece can also make its own threat at the same time, discovered attacks often create two threats in one move. A discovered check — where the revealed attack is check — is especially powerful, since the opponent must deal with the check first, giving the moving piece a completely free move elsewhere.

Double attack

A broader term for any single move that creates two threats at once — a fork is a double attack made by one piece; a discovered attack is a double attack made by two pieces working together. Recognising "does this move threaten two things?" is the single most useful habit for spotting tactics.

Back-rank mate

A checkmate pattern where a rook or queen delivers mate along a player's own back rank (rank 1 for White, rank 8 for Black) because the king has no escape square — its own pawns, usually left unmoved in front of it, block every square it could step to. This is one of the most common ways beginner games end, and the standard defence is simple: give your king a little "luft" (an escape square) by pushing one pawn in front of it once the position has settled.

How to actually get better at tactics

1. Solve puzzles regularly. Pattern recognition is built through repetition — chess.com and Lichess both have large free puzzle libraries.
2. Before every move, ask: "what does this move threaten, and what does it allow?" Most tactical blunders come from missing an opponent's threat, not from failing to find your own.
3. Look for undefended pieces. Most tactics work because something was left undefended, or defended by only one piece that can be removed or deflected.
4. Check every move for checks, captures, and threats — in that order — before deciding on a quieter move. This habit alone catches the majority of tactical opportunities.

Frequently asked questions

What's the difference between a fork and a double attack?

A fork is a double attack made by a single piece attacking two targets at once. "Double attack" is the broader term and also covers tactics like discovered attacks, where two different pieces create the two threats.

What's the fastest way to improve at tactics?

Solving tactics puzzles daily, even just 10–15 minutes, builds pattern recognition faster than almost anything else in chess improvement.

Why do knight forks work so well?

Because a knight's move pattern is unlike every other piece — its attacked squares are easy for both players to misjudge, so forks involving knights are missed more often than forks by other pieces.
