How do I spot a discovered check in a chess puzzle?

Look for a piece that is currently blocking another attacker’s line to the enemy king. If moving that piece creates a direct check, the move may be a discovered check. These are especially dangerous when the hidden attacker is a queen, rook, or bishop with strong line control.

What is a double check in classical chess?

A double check happens when two pieces attack the king at the same time, usually through a discovered move. It is one of the strongest tactical motifs because the king must respond to both threats at once. In practice, that often leaves only king moves as legal replies.

How can I improve at mate in 2 puzzles?

Start by scanning for checks, captures, and threats in that order. In mate in 2 positions, the first move is usually forcing and the second move finishes the attack. Train yourself to calculate the opponent’s only legal responses before choosing a candidate move.

What is the difference between a fork and a discovered attack?
