Outstanding. Most novel feature: auto-adjusts to your skill level (if you want it to). Another clever feature is a speedometer-shaped meter that lets you know if your current position is stronger or weaker than your opponents. Finally, this app incorporates a very strong, highly adjustable chess engine. As a possible downside, recognize that this app does not provide a platform for 2 human players to play each other.
