93/100

tChess Pro is widely regarded as one of the best chess apps ever made for the iPhone, striking a perfect balance between professional features and an accessible interface. For beginners, it’s a revelation; unlike most engines that just make random blunders to be 'easy,' tChess Pro uses specialized algorithms to simulate human-like play, making the lower levels feel much more educational.

For experts, the strength of the engine is formidable—over 380 ELO points stronger than many of its competitors. The Analysis Mode is world-class, providing real-time feedback on the best moves and current winning probabilities. The inclusion of an integrated 'Learn Chess' e-book and a massive 75,000-move opening library makes this a complete chess school in your pocket. Whether you're playing online matches or studying master games, tChess Pro is a powerful, elegant tool that justifies its 'Pro' moniker.
