Most blunders happen because of one of the following issues, or a combination of them:
- Overlooking Opponent’s Threats – You didn’t pay full attention to what your opponent had in mind.
- Ignoring the Downsides of Your Move – You didn’t consider the consequences of your move, such as leaving a piece undefended.
- Weak Visualization Skills – You didn’t fully foresee how your move would affect the position.
- Lack of Board Awareness – You didn’t keep track of the overall position, particularly pieces influencing the board from a distance.
- Poor Tactical Skill – You didn’t see the tactical continuation because you weren’t sufficiently familiar with the pattern.
