5. Advanced Timing Modes
The FCXJTU Digital Chess Clock Timer offers several advanced modes for varied gameplay:
5.1 Bonus Mode
In Bonus Mode, a set amount of time is added to a player's clock after each move. This is often used in competitive play to prevent players from running out of time.
5.2 Delay Mode
Delay Mode introduces a short delay before a player's clock starts counting down after their opponent makes a move. This allows players a brief moment to consider their next move without consuming their main time.
