Knights vs. Bishops.

In chess, the standard point system assigns a value of 3 points to both bishops and knights. However, this simplistic valuation does not always reflect their true worth in a game. The relative strength of these pieces depends on various positional factors such as board structure, piece activity, pawn formations and endgame scenarios. In this article, we will explore how bishops and knights can have more or less value than the basic 3 points assigned to them.

Understanding the Standard Valuation

The reason bishops and knights are both valued at 3 points is because on average, they contribute equally to a game. However, their strengths and weaknesses are very different:

• Bishops move diagonally across the board, covering long distances quickly.

• Knights move in an L-shape and can jump over pieces making them uniquely powerful in closed positions.

Despite their equal nominal value, context is key in evaluating their effectiveness in a given position.

When Bishops Are More Valuable Than 3 Points

1. Open Positions

In open positions where there are few central pawns, bishops thrive. Their long-range movement allows them to influence both sides of the board simultaneously. This often makes a bishop stronger than a knight in these scenarios.

Example: In an open Sicilian or Ruy-Lopez Exchange variation, the bishop pair (two bishops working together) dominates knights because of their long-range power.

2. The Bishop Pair Advantage

A single bishop may be roughly equal to a knight, but two bishops together (often called the bishop pair) can be significantly stronger than two knights or a knight & a bishop. The two bishops complement each other by covering all squares whereas two knights lack this flexibility.

Example: In endgames, the bishop pair can be worth up to 7 points, since they dominate knights & restrict the enemy king’s movement.

On an open board, the rook only has 2 available squares left! The two bishops, along with the king are capable of controlling the rest.

Here’s the main 2 bishops vs 2 knights difference. In this position, the two bishops keep an eye on the kingside as well as the queenside. The bishop is a long-range piece so it can play on both sides of the board at the same time!

3. Endgame Superiority

Bishops tend to be more powerful than knights in endgames due to their ability to control distant squares. In positions with passed pawns or pawn races, bishops are often superior because they can stop a queening pawn from a distance whereas knights struggle to cover long distances quickly.

White’s double bishops are controlling the board. The b7 and f7 pawns are under attack. And once the knight leaves the d7 square, the bishop is ready to go to f8 & destroy the kingside pawns.

When Knights Are More Valuable Than 3 Points.

1. Closed Positions

In closed positions, knights outperform bishops. Because bishops are limited by pawn structures, they can become passive when blocked by pawns. In contrast, knights can hop over obstacles and remain active.

Example: In the French Defense or King’s Indian Defense, knights often outshine bishops due to the pawn chains restricting diagonal movement.

As you can see, the position is closed and white’s bishop pair is very limited – both due to their own pawns and also because of Black’s. They don’t have open diagonals, and there’s no opportunity for them to pressure or attack a weak pawn in black’s position.

On top of that, the knights have many outposts, and as we know, these make for excellent squares to place them.

2. Outpost Domination

A well-placed knight on an outpost (a strong central or advanced square protected by a pawn) can be worth more than a bishop. This knight exerts pressure and cannot easily be dislodged making it an incredibly powerful piece.

Example: A knight on d5 in a Sicilian structure can be worth as much as a rook due to its strong positioning and influence.

3. Forking Power

Knights have a unique tactical strength: forks. A knight can attack multiple pieces simultaneously, creating devastating tactical opportunities that are not available to bishops.

Example: A knight fork between a king & queen can decide a game instantly, making it far more valuable than its standard 3 points.

Exceptions and Special Cases

1. Minor Piece Imbalances

• A bishop and knight combination is often stronger than two knights.

• A single bishop may sometimes be inferior to a knight if the bishop is trapped behind pawns of its own color.

2. Middlegame vs. Endgame

• Knights tend to be stronger in the middlegame, where the board is still cluttered.

• Bishops tend to be stronger in the endgame, where they can dominate long-range.

3. Influence of Pawns

• Pawns that are locked or form a closed structure favor knights.

• Open pawn structures favor bishops.

Final Thoughts: The True Value of Bishops and Knights

While chess assigns bishops and knights an equal value of 3 points, real-game situations often show that their value fluctuates based on position and strategy. Understanding these nuances can give you an edge over opponents who blindly follow point values without considering positional factors.

Key Takeaways:

• Bishops are more valuable in open positions and endgames.
• Knights shine in closed positions and outposts.
• The bishop pair is worth more than a knight and bishop combination.
• A knight in an outpost can be as strong as a rook!
• Tactical opportunities (forks, sacrifices) can shift the value of either piece drastically.

This write-up isn't a comparison of both pieces, neither a guide on how to use which piece on what stage, This is just a mere insight based on my limited experience and study of what piece you would wanna give more importance to based on the situation on the board, which piece to save up, which piece is or isn't worth trading off. Ultimately, the value of bishops and knights is dynamic, not fixed. The best players adjust their evaluations based on position, structure, and strategic needs rather than blindly following point systems. By mastering the subtle strengths of each minor piece, you’ll take your game to the next level.
