How do I spot a fork in a chess puzzle?

Look for one piece that can attack two or more valuable targets on the next move. Forks are easiest to find when the opponent has loose pieces, an exposed king, or a tactical weakness created by the last move. In a chess quiz, always scan checks, captures, and threats first.

What is a decisive material gain in classical chess?

A decisive material gain means you win enough material that the position becomes clearly favorable, often by forcing trades or exploiting a hanging piece.
