# (Abel)
# 1. This PGN file is originated from crafty site, named gm2600.pgn.
# It is a carefully selected collection of games of grandmasters
# over 2600 ELO points from different openings.
#
# 2. Don't attempt rebuilding if you don't have enough memory, this
# would result in sllllllow rebuilding.
#
# 3. Not noarch, db format depends on endianess of machine
#
# 4. Only sjeng opening book for normal international chess provides
# sjeng-book, for other chess variants this virtual package is NOT provided

# probably I'll build book for phalanx in the future too

# Totally 1562649 positions, multiply it by 36 byte and that's
# the amount of memory needed to sort the buffer in one pass.
# It's not much, so assumes such amount of memory is already
# available.  Otherwise please tune -b option. Using the exact
# number of positions seems to segfault for me, while num+1 is fine.
# DB building time increases exponentially(?) when memory available
# decreses.
#
# Since this file records grandmasters' games, include more
# move to give more variability (50), instead of using the
# default value (80) which includes only better gameplay.
# Only includes common moves would be uninteresting.
