How do I spot a fork in the middlegame in classical chess?

What is a crushing fork in a chess puzzle?

A crushing fork is a tactical shot that wins major material or creates a decisive position by attacking multiple pieces at once. It usually comes with tempo, such as check, and often exploits an overloaded defender. These puzzles reward careful scanning of forcing moves.

Why is king safety so important in a London System puzzle?

The London System can create strong piece coordination, but if the king is exposed or the center is unstable, tactical shots appear quickly. King safety matters because checks become more powerful when escape squares are limited. That is why many London System middlegame puzzles feature forks and discovered attacks.

How do I find the best move in a tactical game review?

Start with checks, captures, and threats, then compare which move creates the most forcing pressure. In game review, ask whether a move wins material, overloads a defender, or traps a piece. The best tactical move is often the one that combines several of these ideas.

What should I look for when a piece is overloaded?

An overloaded piece is defending more than one weakness at the same time. If you can attack both responsibilities with one tactical idea, the defender may fail to protect everything. This is a common theme in winning combinations and decisive material gain puzzles.
