I am gradually rolling out version 6.1.1 of Chess for Android to Google Play.  Besides some internal cleanup and refactoring, the major new features are: simple FICS client (see details at Connecting Chess for Android with FICS ) improved electronic chessboard support (DGT/Certabo/Millennium) rudimentary DGT chess clock support (shows moves) The FICS interface is simple, in line with the design philosophy I have always followed so far.  Despite the simplicity, the client is fully functional, and I have started to enjoy playing online over an actual chessboard myself. Hopefully others will find the combination of an electronic chessboard and online play just as enjoyable! A big thank you to my testers! Writing a client from scratch was a non-trivial task, and took a long time. Having awesome testers was extremely helpful during the initial development. Any remaining bugs are mine, of course. Please send me the details if you find one.

It took me a bit longer than planned, but I finally finished the alpha version of a FICS (Free Internet Chess Server) interface in Chess for Android. Either play directly on a phone or table, or first connect to an electronic chessboard (DGT, Certabo, and Millennium) to play over an actual chess board with people online. To connect to FICS, long press the notation window in Chess for Android to open the extended menu. Then select "Connect to FICS" and login as a guest or using your register username and password. The formula string can be used to filter out match requests. For example time >= 5 & inc = 1 only accepts games with at least five minutes start time per player and exactly one second increment per move. The formula syntax is explained in more detail on the FICS help page. Once connected, your username or temporary guest name is shown at the bottom of the screen. Match requests that pass the filter are shown in a dialog with the player names and ga...

I am rolling out version 6.0 of Chess for Android, through the usual Google Play channel . The new features include: Two new sets of chess pieces by Maurizio Monge (who very kindly gave explicit permission) Ability to enable/disable saving engine annotations in the PGN file Opening the draw/resign dialog now requires tapping one king then the other Simpler permission model for "older" Android versions The last change, adding bluetooth and network permissions, is needed so that pre-api23 versions of Android can also connect with electronic chessboards over bluetooth or with remote chess engines over a network socket (the latter is also needed for an upcoming FICS client I am working now). From api23 onward, users can selectively enable or disable such permissions. Pre-api23, however, it was an "all-or-nothing". Changes like this have unfortunately the danger that some users will uninstall, but in the long run I believe I can better serve the full customer ba...

I just released version 3.3 of Chess for Android, available at Google Play or as direct download . The new features include: Ability to modify filenames of regular and tournament games. Information on network status during socket setup. In the older versions, regular games and tournament games were alway appended to, respectively, the files games.pgn and tour.pgn on SD card. The new feature allows users to change these defaults through a "Change pathnames" menu. The pathnames can even include subdirectories, provides these directories exist.   The second feature displays information on the network status during socket setup (mobile connection, Wifi, etc.). In the version without network permissions (the default on Google Play), a proper warning message is shown instead.  

As a follow-up on the previous posting and for users that want to experiment with a remote chess server without setting one up themselves, I have, very temporarily, set up a remote chess server with various engines at ports  2000  through  2005  on  aartbik.dyndns.org . Simply type this hostname and one of the ports in Chess for Android and let me know if you were able to connect!

I have received several questions on how to connect Chess for Android running on an Android device (e.g. a phone) as client to a remote chess server (e.g. a powerful desktop), so I decided to write a small document with detailed instructions. What you will need: The server software from Bernhard Wallner's chess utilities , suited for your server's operating system (if, say, your desktop runs Windows, you will need to download the Windows version). You do not need to download the client software in this case. The network enabled version of Chess for Android . On the server, start the engine server software, and construct a new row for every engine you want to run remotely. Assign a name, port number, and select the full path to each engine binary (an executable that runs on the server). You can also supply command line options for starting the engine. Check the active checkboxes and click start when done. This yields something similar to the screenshots below. Here, I have s...

User PJ+ at the OpenChess forum implemented a nifty client utility that converts Chess for Android to a client for a remote chess server. To make this work (assuming you already have a remote chess server running at some hostname and port), simply do the following steps. Download the version of Chess for Android that grants network permission to its UCI clients (the default version at the market does not do this for obvious security reasons). Download PJ+'s client-android-cli utility. Construct a file, for example uci_client , that contains the single line ./client-android-cli <hostname > < port > for the hostname and port of the remote chess server. Copy 2. and 3. to SD card, then install these from SD just like the first-time install of UCI engines. Finally, the single line file uci_client can now be imported as any other UCI engine, and will connect to the remote chess server. I tried this method myself connecting Chess for Android as client to a remote c...
