# This is a collection of blunders of GNU Go in Stefan Mertin's private
# 13x13 - Computer Go tournament in 2001 (see
# http://www.geocities.com/comp_go/13x13.html). I think they should be
# quite useful as tests. 13x13-positions are specific as problems, and
# they are quickly evaluated both by GNU Go and by us when maintaining.
# (And of course, these are games against some opponents we would like
# to beat :-) )
# I also added a few test cases where GNU Go played right in the game,
# but went wrong in a replay by a newer version (3.14 / 3.15).
# -Arend
# Most of the variations in the sgf-files are due to Stefan Mertin.
