Chess for Android 2.9.4

-
I just released version 2.9.4 for Chess for Android, available from the Android market or as direct download. This version introduces the much requested "infinite analysis" mode for an imported UCI engine, in which the engine reports its analysis of positions without actually making moves. To enable this mode, change the level to free play, as shown in the following screenshots.




If an UCI engine is imported, its analysis of the current position will appear below the board. The user can freely play through previous games or make new moves. When at the end of a game still in progress, pressing the ">" button will play the best move found by the UCI engine. Changing the level, or unloading the UCI engine will exit the "infinite analysis" mode.

Although the feature may seem simple, it was actually far from straightforward to implement, also because not all UCI engines behave the same for the "go infinite" command. Please let me know if you encounter problems or if you have suggestions.

Checkers Move Generation

-
I was able to make a small improvement in the checkers move generator (written in Java for the Android SDK). The following table shows run times of several perft depths before and after optimization when run on the emulator (which should mimic actual run times on the phone quite well). DEPTH #LEAF NODES ORIGINAL OPTIMIZED TIME TIME ==================================== 7 179740 2.9s 1.9s 8 845931 14.2s 9.7s 9 3963680 66.3s 45.6s 10 18391564 294.6s 208.7s P.S. Runtimes for a C++ checkers move generator on a 2.2 GHz Core 2 Duo are given at my checkers page .

Connecting Chess for Android to a Remote Server

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

Connecting with the DGT Board

After all the fun I had connecting Chess for Android with the Millennium  over Bluetooth, I was curious if I could provide similar support for the DGT electronic chess boards. Some of these have Bluetooth capabilities, most use USB connections, and some older models, like the one I have, still use the RS-232 connector. To my pleasant surprise, by combining the original serial cable of DGT with a USB-to-serial cable and a female-USB-to-USB-C cable, I was able to get an actually working connection between my DGT board and my tablet or phone. Next was implementing support in Chess for Android. Luckily, DGT kindly shared the protocol documentation with me, and after a fun weekend of hacking, Chess for Android now proudly supports DGT electronic chess boards as well.
