“Invincible: The Games of Shusaku,” John Power’s classic and widely-acclaimed masterpiece on one of the greatest go players who ever lived is now available in SmartGo Books. Originally published by Kiseido, the SmartGo Books edition of Invincible “includes the complete text, games, and diagrams of the print edition, painstakingly converted to digital format,” SmartGo’s Anders Kierulf tells the E-Journal. “And it takes full advantage of the digital medium – be prepared to experience this classic in a whole new way.” Features of the new edition include the ability to replay moves in figures and diagrams, play out your own variations, fewer moves per figure, with the appropriate text for each figure, and inline diagrams for move sequences embedded in the text. Best of all, the new edition’s portable accessibility on iPad or iPhone means Invincible — at an introductory price of $19.99 – can now always be with you. SmartGo Books is a free app for the iPad and iPhone available on the App Store. Check out free chapters of over 30 go books and purchase those you like using in-app purchase.
