DoubleCheck 1.1 for Android

-
I compiled Lucas Braesch's DoubleCheck 1.1 for Android (ARM) and put it on the UCI Engines for Android website. The engine works reasonably well in Chess for Android. However, because the UCI command movetime is not implemented yet, it plays almost instantaneously, making matches to determine its strength less useful at the moment.

Optimal settings depend heavily on the actual device as well as on the particular chess engine; on a single core CPUs should be 1; hash size of 32MB and TB cache of 8MB usually perform well. Limit ELO is only supported by a few engines, and reduces the playing strength up to the given ELO.

THank you for your CFA because I can play many oponents (engines) and so different styles.Very functional game.i think for the future you will make it to run an .exe engines.I realy wanna test TheKing chess engine ( the engine behind Chessmaster) and the other main chess features.

I am glad you enjoy Chess for Android. Note that .exe files are Window binaries. Android devices typically run only ARM or x86 binaries. See UCI for Android for some background. You could try to convince Chessmaster to release an Android version ;-)

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.
