Arasan Test Suite

arasan12.epd contains a set of 238 chess problems, drawn from a variety of human and computer games. They range in difficulty, but most are non-trivial and some are quite hard. This is the latest version of the test suite. Some positions in this file are "avoid move" positions where there is a bad but superficially tempting move. The testsuite was last modified 15-Aug-2010 (adding some positions and modifying one).

You can browse the test positions online here and also can download them in a single file via this link:
