You will learn this rule from several illustrative examples, including the games of Bobby Fischer himself, in which he has implemented this golden chess rule and won games easily!

Check out the below examples and find the best move.

Example 1: Which Black Piece to Trade?


White to play
Example 2: Is Rb2 a Good Move for Black?
Black to play

In Example 1, White decided to trade off bishops. Afterward, White moved their knight to h1. And suddenly Black played Nxh3 and the f3-knight is hanging.

As a result, Black won a pawn and destroyed White’s pawn structure.

In Example 2, It’s Black’s turn to play. Black attempted the move Rb2, attacking pawns on the second rank. However, White has a simple checkmating plan involving moving the pawn to h5, followed by queen to g7. Black ends up in a hopeless position.

Bobby Fischer’s Golden Chess Rule:

From what I can see, when people lose games like these, they often believe they need to solve more tactical puzzles or find a way to avoid blunders.

But the reality is there’s a common pattern. White had a piece in Black’s half of the board.

The queen on f6 is the most advanced piece and is putting pressure on Black’s position. It’s ready to create some checkmating threats.

Bobby Fischer’s Golden Chess Rule: If you see an opponent’s piece in your half of the board, you need to neutralize it.

It’s always useful to ask yourself, “What is my opponent’s most active piece?” and try to neutralize it.

You can do this by exchanging it or attacking it.

Going back to the previous examples, Black’s most active piece on White’s half of the board is the knight on f4. As long as it stays there, it will create some unpleasant threats.

It makes sense to think about ways to neutralize this knight. White could play Nf2, offering an exchange of knights.

If the knights are traded, White’s position would become completely safe.


The overarching principle we’ve learned today is Bobby Fischer’s invaluable rule: neutralize your opponent’s most active piece to minimize threats and optimize your position on the board.

As we’ve seen through multiple examples, applying this rule consistently can not only prevent blunders but can also set the stage for a successful counter-attack.

This rule is simple yet effective, making it a powerful tool for chess players of all levels.
