Relative Pin Chess Trainer: Examples, Replays & Practice

A relative pin is a pin where the pinned piece may legally move but doing so exposes something more valuable behind it. The move is legal, but the consequence is usually material loss, mate, or a decisive positional collapse. Start with the Pin Pressure Adviser, then solve Xie Jianjun vs Yu Lefu to feel the difference.

A relative pin can be broken legally, while an absolute pin cannot be broken if moving the pinned piece exposes the king to check. The practical question in a relative pin is whether the hidden target is worth the risk. Compare the quick definition table with the Oren vs Dyner and QGD trap cards.

Yes, a relatively pinned piece can move because the king is not necessarily exposed. The danger is that moving may lose a queen, rook, defender, mating square, or key pawn. Use the Practice this position button on each trainer card and test whether moving the pinned piece survives.

A relative pin is powerful because it turns a legal move into a bad choice. The defender may be allowed to move the piece, but moving it abandons the target behind it. Use the Reveal answer panel on Xie Jianjun vs Yu Lefu and name the target that collapses after the first move.

Bishops, rooks, and queens create relative pins because they attack along diagonals, files, and ranks. Knights and pawns cannot create line pins, although they often exploit pinned pieces. Use the model diagrams and identify the line piece before replaying the solution.

Knights, bishops, rooks, queens, and pawns can all be relatively pinned if moving them exposes a more valuable target. Knights are especially vulnerable because they cannot slide along the pin line. Use Capablanca combination and Petroff opening mistake to compare knight-related pin pressure.

No, the hidden target can be a queen, rook, mate square, defender, pawn, or open line. The value of the pin depends on what is lost after the pinned piece moves. Use Nimzovitch vs Nielsen and Karaszev vs Klamen to see pins based on squares and pressure, not only queen wins.

The easiest practical example is Xie Jianjun vs Yu Lefu because the first move removes a defender and the follow-up is forcing. It shows that the pinned side can move legally but still cannot solve the bigger tactical problem. Start there, reveal the answer, then replay the line.

Exploit a relative pin by increasing pressure, removing a defender, decoying the target, or switching to the hidden weakness behind the pinned piece. Do not assume the pinned piece is helpless until you calculate its best resource. Use the adviser’s material setting and then practise the recommended FEN.

No, capturing immediately is not always best. Sometimes you should add pressure, improve a piece, or force the target behind the pinned piece onto a worse square first. Use Capablanca combination and Oren vs Dyner to compare buildup with immediate action.

A decoy drags a queen, rook, king, or defender onto the wrong line so the relative pin becomes stronger. The tactic works because the target behind the pinned piece becomes easier to attack. Use Oren vs Dyner and Lasker vs Ayala to study decoy-to-pin patterns.

Deflection removes a defender from its job so the pinned piece or hidden target becomes vulnerable. In many combinations, each forced capture makes the next pin stronger. Use Rubinstein combination and Bronstein vs Goldenov to see deflection supporting pin pressure.

Yes, a relative pin can lead to checkmate when the pinned piece guards an escape square, blocks a line, or protects the mating defender. The target behind the pin can be a mate square rather than material. Use Nimzovitch vs Nielsen and Supercool Nimzovitsch to see pin pressure feed the king attack.

A partial pin is a pin where the pinned line piece can still move along the line without fully abandoning the target. Queens, rooks, and bishops sometimes have this resource. Use the practice buttons and check whether the pinned piece has a safe line move before assuming it is trapped.

Yes, a queen can be relatively pinned if moving it exposes mate, a decisive rook, or another tactical target. Queen pins are often practical rather than legal because the queen still has many possible moves. Use Lasker vs Ayala and Oren vs Dyner to see queen-related pin pressure.

Yes, a pawn can be relatively pinned when moving it opens a file, diagonal, or mating square. Pawn pins near the king are especially dangerous because one pawn move may expose a decisive attack. Use the adviser’s king attack option and then review the dark-square examples.

In a pin, the restricted front piece is attacked because a more valuable target sits behind it. In a skewer, the valuable front piece is attacked first and must move, exposing what is behind it. Use the comparison section, then follow the InGuides link to the skewer trainer.

A fork attacks two targets at once, while a relative pin restricts one piece because moving it exposes a hidden target. Forks are about simultaneous attack; pins are about line restriction. Use Capablanca combination because it shows how fork and pin pressure can overlap.

A discovered attack moves your piece to open a line, while a relative pin restricts the opponent’s piece because of what sits behind it. The moving side and the restricted side are different. Use Petroff opening mistake to see how discovered-check ideas can combine with pin pressure.

Defend by moving the hidden target, blocking the line, trading the pinning piece, adding defenders, or creating a stronger counter-threat. Because the pinned piece may legally move, counterplay is often possible. Use QGD trap after Nxd5 to practise the defender’s resource.

Ignore a relative pin only when the exposed target cannot be punished or your forcing sequence is stronger. It is a calculation decision, not a rule. Use QGD trap after Nxd5 and ask why Black can move the apparently pinned knight.

Unpinning means removing the restriction on a pinned piece by moving the target, blocking the line, trading the attacker, or creating a tactic that makes the pin irrelevant. Good unpinning often happens with tempo. Use the adviser’s defend setting and test your answer in the sparring board.

Beginners often check whether a move is legal but forget to ask what it leaves behind. Relative pins punish that exact blind spot. Use the Reveal answer buttons and say the hidden target aloud before checking the solution.

The pin may have been only cosmetic if the hidden target was protected or the move created a stronger threat. Relative pins are not legal cages, so they must be calculated. Use QGD trap after Nxd5 as the reminder card before assuming a pin wins.

Identify the line piece, pinned piece, hidden target, and forcing moves. Then check the defender’s captures, checks, blocks, and counter-threats. Use the Pin Pressure Adviser and select your goal to get a focused calculation route.

Look for a long-range attacker, a front defender, and a valuable or decisive target behind it. The best pins also limit the pinned piece’s safe trades and counterplay. Use the model cards from Xie to Karaszev as a five-position scan drill.

Yes, opening pins are common when a bishop or queen pins a knight to a queen, rook, or central target. The pinned piece may move, but doing so can lose development or material. Use Petroff opening mistake and QGD trap after Nxd5 to compare opening pin decisions.

They are most common in middlegames because more pieces and targets remain on the board. They still matter in endgames when rooks, passed pawns, and key defenders line up. Use Capablanca combination for an endgame-style pressure example.

Practise by solving positions where you must decide whether to add pressure, capture, decoy, or ignore the pin. The key skill is judging consequences, not just naming the motif. Work through the trainer cards, reveal the answer, replay the solution, then practise the FEN.

After relative pins, study absolute pins, skewers, forks, and double attacks. The same line-geometry and loose-target ideas appear across all of them. Use the InGuides links and the tactic course callout after finishing the trainer.
