Arasan Test Suite

arasan14.epd contains a set of 175 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 03-Mar-2012.
