Chess visualization is the secret weapon of Grandmasters. Can you calculate moves in your head without seeing the pieces? The ChessFlow Blindfold Trainer helps you master this skill.

This tool offers two powerful modes: Color Vision (identifying square colors instantly) and Knight Vision (calculating Knight jumps without arrows). Regular practice with these drills will significantly improve your board awareness and tactical calculation.

Training Modes:

• Square Color Drill: Quickly identify if a square (e.g., e4) is Light or Dark.
• Knight Vision: Find every possible square a Knight can jump to from a random position.

How to Use This Trainer

1. Select Mode: Use the tabs to switch between "Color Vision" and "Knight Vision".
2. Color Vision: A square coordinate (e.g., g5) will appear. Click "Light" or "Dark" as fast as possible.
3. Knight Vision: A Knight will appear on the board. Click all the squares it can legally jump to. Once you find all of them, click "Next Round".

Practice this for 5 minutes daily to see a noticeable improvement in your calculation speed.
