Obviously the best Chess platform on Android. That's not saying much, even a dog pile has a top turd. It's not that bad though. My complaint is Casual mode is too easy. The AI constantly falls for the opening 4 move Kings Bishop & Queen+Queens pawn checkmate. On the flipside ,pro mode is far too brutal.. with no happy medium, a journeyman player like myself gets turned off of this app quick... good news I love the 3D setups, would like to see more Staunton styles and colors added.
