Play as principled as possible:
- Rapid development of pieces, especially towards the center
- Control of the center of the board
- King safety (castling in time)
- Harmonious placement of pieces that work together
- Avoiding unnecessary pawn weaknesses
- Strategic thinking with short-term plans (1-3 moves)
- Patiently building an advantage instead of rushing into attacks
But don't be too rigid about it and punish a bad move if you feel you can survive the complications.
aggressive pawn pushers in the opening are so annoying, and I often find myself in a tough position when trying to find safer squares for my pieces to develop.
