    Default Release: Abaia (chess program)
    Hi all,

    I've just released a beta version of Abaia, the strongest chess program for the iPhone so far. This is still just a beta: It is not quite feature-complete, and has a few rough edges. There is still no handicap mode, the program always plays at maximum strength.

    Installation instructions and the URL to the Cydia repository can be found at the link above. An App Store version will be released under the name "Glaurung" in a few weeks.

    Smile Wow!
    Consider me completely stunned.

    First, there should be a thousand people here thanking you. What you've done is utterly impressive.

    I have Chess Genius and it plays a pretty good game. But Abaia is a better program in nearly every way. First, the chess set looks better. Second, this program is stronger and much more aggressive. Third, Abaia seems to adhere better to Apple's UI standards. And, fourth, it's FREE. Wow.

    I haven't seen a single rough edge yet.

    I pitted my jailbroken iPod touch 2G running Abaia against my wife's non-jb touch 2G running Genius. Genius did manage to win one of three games, but only after having been outplayed as White until Abaia made one mistake in the late middlegame. The other two games were all Abaia. And watching the relative evaluations was enlightening: Abaia's was nearly always far more "aggressive" in that it showed the potential of a brewing attack far more.

    The first game between them was truly amazing in that Abaia sacrificed a pawn on the queenside for a very long-term kingside attack, even after the queens had been exchanged. The attack was pursued steadily and patiently for seemingly dozens of moves before it paid off. Simply incredible for a program playing on a handheld against the previous king of the hill -- and both programs were set on their 3-second-per-move level!

    I saved the game score; if I knew how to get it to my PC I'd enter it here. It's really something.

    So, ultra-kudos and mega-thanks to you!

    EDIT: Here's the score of the first game vs. Chess Genius, both on (separate) iPod touch 2G units, 3 seconds-per-move level:

    Hi Tord,

    I can't thank you enough for this wonderful release! This is by far the strongest engine out there. I tested it on an iPhone 3G with firmware 2.1, and it crashed couple of times, but this does not take a bit away from its beauty!

    Thank you so much!

    Mihailo.

    Hi. Not sure if you're collecting data for future development. I ran into this big problem:

    I played several games successfully. After the seventh game, I decided to quit ( having lost 0-7!). I hit the home button when the announcement that black had won was still showing. I thought that this might be a mistake but thought little of it. When I started it up again to have another go at it, it crashed back to the homescreen without ever starting up. I uninstalled it, rebooted, reinstalled , and I get the same results wheever I try to start it up. It's like I'm permanently stuck with an automatically crashing program

    I'm an iPhone 3g running fw 2.2

    Of course I am -- thanks a lot for reporting this problem!

    Shouldn't matter, you made no mistake. The program should be able to handle this, of course.

    When I started it up again to have another go at it, it crashed back to the homescreen without ever starting up. I uninstalled it, rebooted, reinstalled , and I get the same results wheever I try to start it up. It's like I'm permanently stuck with an automatically crashing program
    If you can't start the program, even after multiple attempts, the only explanation I can see is that the preferences file has somehow gotten corrupted. If you delete it, the program should work again. If it is not too much of a problem, I would appreciate if you could e-mail me the preferences file before you delete it, in order to help me find out exactly what went wrong.

    The preferences file is named com.glaurungchess.abaia.plist, and is found in the directory /var/mobile/Library/Preferences/ on your iPhone.

    Best wishes,
    Tord

    Yes! It worked! I also kept the file for your review. But, I don't know how I'm supposed to obtain your e-mail in order to send it to you. Let me know what to do next.

    You'll find my e-mail by pressing the "Options" button, scrolling to the bottom of the menu, and choosing "About/Help".

    Version 1.0.1 is now available, and upgrading is strongly recommended. Several important bugs are fixed, and the program is much more stable and reliable than the 1.0 version.
