# Current Task
Working on chess piece recognition with the updated ML model that includes empty square detection.

# Recent Changes
1. Empty Square Detection:
   - Handle empty_dark/empty_light classes
   - Exact class name matching
   - Proper error handling

2. Position Validation:
   - Allow moved pieces

   - Piece count tracking

3. Error Handling:
   - Better error messages
   - Clear logging
   - Fixed optional unwrapping

# Next Steps
1. Recognition Tuning:
   - Fine-tune empty square detection
   - Adjust confidence thresholds
   - Improve position validation

2. Model Training:
   - Add more empty square examples
   - Include different board styles
   - Improve piece variety
