Whoops, looks like I was announcing new versions of tChess on the Facebook page and forgot to update this page.
The new version of tChess (version 1.9.0) was just released this morning and it adds a major new feature:
the ability to play games with other people over the Internet via my own proprietary tChess server.
This feature should be much easier to use and much more reliable than the old system
of playing online games via Game Center.

tChess version 1.8.3 just became available for download on the App Store. This release supports the iPhone 6/6+
display resolutions natively. It also includes a major new feature,
which displays a graphical overview of the current game within seconds.
To my knowledge, tChess is the only mobile chess app with this feature.
December 3, 2013
tChess version 1.8.2 is now available. Many users have asked for a quicker way to access the list of turn-based
Game Center games, so the new version allows customization of the main toolbar (via the "Interface" tab of the main menu)
and the ability to add a Game Center button. The new version also has support for certain PGN files with unusual formatting
and fixes a crashing bug that occurs with iOS 7.
September 26, 2013
tChess version 1.8.1 is now available. In an attempt to make tChess look more like a native iOS 7 app, its background
color was changed to white in version 1.8. Many users did not like the new look, so an option has been added
to change the background color to black. This option can be found in the Appearance menu (Interface tab).
September 18, 2013
tChess version 1.8 was just released to the App Store. It now uses the PGN format to represent games internally,
which is the biggest single change to the app since it was released almost 5 years ago. This gives tChess the ability
to handle arbitrary PGN tags and multiple annotations,
Numeric Annotation Glyphs,
and variations (including recursive variations!) per move.
The look of tChess has also been updated to match Apple's new design language for iOS 7.
June 27, 2013
tChess version 1.7.5 is now available on the App Store. It might have the highest number of user-requested features
of any tChess update ever.
Headline features include: the ability to play Game Center games between tChess Lite and tChess Pro (recently made possible
by Apple), the ability to send messages to your Game Center opponents, a self-play mode, printing (via AirPrint), and more.
February 19, 2013
tChess version 1.7.4 is now available. The headline feature for this release is
iCloud support, which effortlessly keeps your entire PGN file library
synchronized between all of your iOS devices. This release also includes many other new features, mostly
related to managing PGN files, which you can read about in the update notes.
September 27, 2012
tChess version 1.7.3 is now available on the App Store. It adds specific support for iOS 6 and the iPhone 5's new
4" screen size, among many other new features that are listed in the update notes.
March 27, 2012
tChess version 1.7.2 has just been released. It adds support for the new iPad's retina display
along with smoother 2-D graphics and an optimized 3-D engine that's over 3 times faster. The biggest
improvement for most users will be the redesigned menu system, which combines the Actions and Settings
menus (that tChess has had since version 1) into one Settings menu with tabs, so it's better organized
and easier to use.
November 7, 2011
tChess version 1.7.1 is now available on the App Store. The biggest change is that it is now
fully translated into German, French, Japanese, Korean, and (simplified) Chinese.
October 12, 2011
iOS version 5 is now available and so is tChess version 1.7. tChess was on the leading edge by being the
first iOS chess game to support real-time Game Center and is now the first iOS chess game to support
turn-based Game Center play (new for iOS version 5!). Another new feature is the oft-requested ability
to view annotations in PGN files, with the bonus that you can also edit the annotations via the
full-screen move list UI. Additionally, tChess is debuting its first foreign-language translation, German.
September 1, 2011
The next update to tChess is ready to go but requires new features that are only found in iOS 5.
Hopefully the rumors are correct and iOS 5 will be released in September.
In other news, tChess is featured in Apple's latest iPad TV commercial, titled "Learn":

Version 1.6 of tChess is online now and may be the biggest update yet!
Ever since the first version of tChess over two years ago, customers have
been asking me for the ability to play others online, and that's now possible
with tChess's new Game Center feature!
Also included in this major update is support for the iPad 2's dual core A5 processor.
I developed my multi-processor search algorithms back in 2002 and this is the first time
I've made them available publicly. Very exciting!
Another new feature is the extended opening library.

tChess version 1.5 has been submitted to Apple for review and will be available
soon. This is the biggest update to tChess since its original release! tChess
now lets you specify an ELO rating to adjust the computer's difficulty, and it
has a new "Profile" feature that allows you to play rated games against the
computer and track your progress. tChess Pro also has a new PGN Database feature
that allows you to download and view databases of chess games (in standard PGN format).
September 23, 2009
The new version (1.4) of tChess is on the App Store now.
Both Lite and Pro get the captured pieces display, and a fix so the toolbar icons
return to their intended size in OS 3.
A new feature in Pro is the ability to Copy & Paste games in standard
PGN format, making tChess Pro one of the (very) few apps that can import games.
September 15, 2009
The next version of tChess (1.4) is currently in testing to make sure it works well
on OS 3.1, 3.0, and older versions of the iPhone OS. The update has many new features,
including the much-anticipated display of captured pieces.

January 1, 2009
Happy New Year!
December 7, 2008
Good news! Both tChess Lite and tChess Pro are in the Top 100 Paid Games list.
November 15, 2008
tChess Lite just went up on the App Store! It's a version for casual players
who want an inexpensive yet high-quality chess game, and don't need the
enthusiast features or maximum engine strength of tChess Pro.
November 9, 2008
I just played a 10-game match between tChess Pro and another chess game on the iPhone,
Caissa Chess. tChess Pro scored 90%, which means tChess Pro is over 380 ELO points
stronger than Caissa Chess.
