Stop Blundering in Chess: Daily Blunder Check Puzzle

The best way to stop blundering in chess is to check every move before you play it. Blunder shows you a move you’re thinking of, and you decide whether it loses anything.

How to play Blunder

1. You see a position from a real game, and an arrow showing a move you’re considering.
2. If the move loses nothing, tap It’s safe.
3. If it does, tap every piece you’d lose after it, including the moving piece itself if it lands somewhere it can be taken, then confirm.
4. After each answer you see why, with the attackers and defenders drawn on the board.
5. There are three moves, from easy to hard. Most right wins; ties go to the faster time.

Tips

• First ask whether the square the piece lands on is safe: what attacks it there, and what defends it?
• Then ask what the moving piece was defending before it left. That is the classic blunder.
• Check for lines the move opens: a piece that moves out of the way can uncover an attack on something behind it.
• Remember pawns can’t move back. A pawn move can leave a square that will never be defended again.
