# attack.db - pattern database for finding tactical attack moves
#
# The tactical reading functions try to capture by attacking
# on the immediate liberties plus certain caps and backfilling
# moves. This database is intended to find additional attacking
# moves. Notice though that these patterns doesn't help the
# tactical reading to find attacking moves later in a move
# sequence but only at stackp=0.
#
# See patterns.db for a specification of the current database format.
#
# Since these patterns are matched during make_worms() it doesn't
# make any sense to use classifications such as X and O. No other
# classification is useful either except A since we only have
# tactical attack moves here.
#
# The semantics of these patterns are that the move at * is tried as
# an attack of each X string in the pattern. The patterns are matched
# with either player as O.
