OpenChess

I just released version 2.8 of Chess for Android, available from the Android Market or as direct download.

New features include:

• (1) full PGN support (clipboard import/export, file load/save),
  (2) improved layout for xlarge screen sizes (api 9 and up)
  (3) bug fix in draw detection after FEN import

To load a game from a file in PGN format, long press the notation window, select "Load Game from SD", and navigate to the file. This opens another window with all the actual games in that file. Simply scroll and select to the desired game. Very large PGN files may take a while to download (or even run out of memory), but the idea here is that future versions will be able to navigate quickly between successive games. I have tried to make the PGN parser reasonably robust (it accepts sloppy SAN for instance), but certain non-standard constructs are rejected. Please let me know if you encounter bugs though.

thanks aart. tested it with a big pgn file ... worked well.

tested it with a database of 1795 games and it worked without problems.

Thanks, Aart! Good effort.

Screen layout is much better.
Pgn works too. I wish there was more feature (Study-mode on/off as in SCID, the arrow button to go to the next game in the Pgn database etc)

Well noted, but writing a PGN parser was a necessary first step....

my favourite wish feature is still a tournament feature.
so that i can watch the engines play in a tournament against each other.

that way i would not need to transport a laptop or netbook with me.

Version v2.8.2 of Chess for Android adds the ability to set the number of processors for UCI engines that support SMP.

Since earlier attempts to get consensus on a standard way to define this in the UCI protocol failed, I simply look for "Cores", "Processors", "Threads", and "CPUs" in the UCI engine options, and then send the proper value using the recognized option name (please let me know if you would like to see other option names).

For the interested, the new UCI setup layout can be seen on this page.

this is marvellous aart. i can now run chess programs with 2 cores, and let them play eng-eng matches against others on my android tablet pc.

i could not do this with my mobile
