3 Key Takeaways


Your game shows a tendency to make moves that weaken your position and/or allow your opponent to gain the initiative. A recurring theme is premature attacks that ultimately lose tempo and hanging pieces.

Here's what to focus on in your next game:

Develop with Purpose: Ensure your moves not only develop your pieces but also control important squares, threaten the opponent, or support your pawn structure. Ask yourself "What does this move do*?"
