It helps you improve by giving you hints during the game. There are 3 types of hints you can use:
- Color alarms for the current position if you have a winning move, if there is only one good move to play, if you played computer recommended move or if you played a bad move.
- Engine score for the current position (with or without color hints)
- One or more engine variations for the current position (with or without color hints)
Chess Coach can also be used for analysis while kibitzing online games with GUIs that don't have engine analysis feature (BlitzIn) or if the engine analysis is disabled by the GUI (e.g. when you are logged in as guest on Playchess).
