Joachim Bondo released an iPhone version of his mobile chess game Deep Green [App Store]. The $4.99 Chess game was originally released for Apple's Newton platform in 1998.

John Gruber, a fan of the Newton version, describes the iPhone release (Gruber is a bit of an interface fanatic):

To be clear, this is not a port but a complete rewrite, with the same attention to detail, graphics, simplicity, and fun that marked the Newton version. For example, Deep Green for iPhone lets you move pieces either by drag-and-drop or by tapping a piece, then tapping the square you wish to move it to. (The tapped piece jiggles while waiting for you to tap the destination square.)

Deep Green also lists some notable features for Chess fans:

  • Play against engine or human, or engine vs. engine
  • Adjustable engine strength
  • Concentration setting allows the engine to play more like a human
  • Manual board setup
  • Playback game (forward/backward, animated replay, drag slider)
  • Take back moves (undo, all the way back to start)
  • Clean and beautiful user interface

    Awesome! I loved Deep Green on my Newton; great to see old Newton classics like this and Deep Space Newt resurfacing.

    OK, I have been desperate for a good chess app, bought almost all of them, and I began to wonder if developers are simply unable two understand three basic requirements:
    - there is only one screen resolution for the iPhone - it cannot be that hard to layout an application accordingly - just shrinking/stretching apps originally made for other devices is not good enough
    - the begin and end of a chess program is the chess engine, if it is no good, then all 3D views, skins, sound and video gimmicks will not make it a good program ever
    - the only features a chess app really needs is good ergonomics, a clear layout, usable touch controls, undo, auto-save, option to show captured pieces and an option to start with a custom game state

    So far only Chess Genius was close to that goal (except for the screen being too crowded at times and the rather ugly layout), Chess Genius, Caissa and Gameloft's Chess Classic had good engines, but the latter is a design nightmare on the iPhone and Caissa's screen is screaming for a stylus.

    Deep Green is easily the best (unless you really need the chess clocks and teacher function in Chess Genius). The layout just asks to be licked, the engine is strong and all essential features are just there without cluttering the screen. A piece of beauty. I would rate it the number 1 choice for experienced players and a close number 2 (behind Chess Genius) for beginners.

    surely will check it out

    btw you spelled Deep Green wrong in the second line ("deep greep")

    'Chess with Friends' allows iPhone-to-iPhone games that are ongoing.

    Make a move, then whenever the other person has a free second, they can make their next move, and so on.

    It's free. I don't know why you'd want any other chess game.

    Chess with Friends.

    I've got quite a few board games including chess apps. All the free ones (ehhh in my opinion) plus tChess and a couple others. Chess with friends is totally diff kind of game...poor for real-time play.

    Some things that make tChess a better game: chess clocks, a move list, reverse/forward buttons on the bottom toolbar to scroll thru the game (I love this), and an analysis mode. It also displays legal moves which helps learning too.

    Deep Green doesn't let you save and name a game. and then it doesn't let you load saved games. It's definitely pretty, but tChess Pro offers more.

    @marv, what a helpful comment, thanks for that! I've been looking over the App store chess games and had pretty much decided on Chess Genius. I know it won't be perfect, but I'm a chess novice and your comment helped me to shore up my decision to go with Chess Genius.

    Anyone else got any good strategies?
