Chess for Android v3.0
Postby AartBik » Tue Aug 30, 2011 6:26 pm
Chess for Android v3.0 is available from the
Android market or as
direct download.
New features include:
(1) The possibility to play engine tournaments from both sides of any external book in PGN format, as explained in this blog posting.
(2) Layout and formatting improvements in the UCI analysis output window. Light grey board color.
(3) Relaxed FEN parsing to accept non-standard, but frequently occurring omissions in the FEN string.
(4) Ability to view simple cross-table while tournament is in progress (>> button).
Opening Test Suites
To eliminate the
effect of opening books, it is a common practice to test the strength of
chess engines by letting them play from both sides of a pre-selected
set of opening positions. Earlier versions of
Chess for Android already supported the option to play engine tournaments from both sides
of 50 positions of the built-in book (yielding 100 games total between
each engine pair). The upcoming 3.0 release will add the option to play
both sides of
any external book in PGN format, such as the famous "
Nunn Positions" (published by GM John Nunn) or the "
Silver Opening Suite" (published by Albert Silver).
To use this feature, long press the notation window, and select "UCI
Engine Support", followed by "Engine Tournament". Then select the "all
games from both sides of external book".
This
will open a file navigation window, starting at the root of the SD
card. Navigate into the directory and file of the desired opening suite.
This will prompt a confirmation window with the number of opening lines
in the suite.
Finally, invite a number of UCI engines to the tournament, and the
tournament will start automatically, where each engine will play each
other engine from both sides of the given opening suite.
