🎯 Tips & Strategy — Chess
- Control the center with your pawns early — e4 and d4 are the strongest opening moves.
- Develop your knights before your bishops — knights need more moves to reach their optimal squares.
- Don't move the same piece twice in the opening — develop all your pieces first.
- Castle early to protect your king and connect your rooks.
- Always think about your opponent's threats before making your own move.
