Before making any move, quickly check if your chosen move allows captures, checks, or tactical shots from your opponent. A 5-second scan can save games.
Look for unprotected or under-defended pieces (yours and your opponent’s). The saying “Loose Pieces Drop Off” is one of the fastest ways to understand blunders.
Imagine your opponent’s best reply before you play your move. Always account for checks, captures, and threats they could play immediately.
Blunders often happen under time pressure. Save a buffer of a few minutes for critical positions and avoid rushing when the stakes are highest.
When you already have a winning advantage, aim for safe simplifications rather than complex tactics. Don’t give your opponent unnecessary chances.
