I have no idea how anything I said had anything to do with crafty.  Because we
do have a Hydra sitting around to test out in our homes we go by what e believe.
 Based on what I have read here including posts by Chrilly and results of games
Hydra has played in the past I believe Hydra to be much stronger than Rybka or
any other known chess entity at this time.  I hope to see Zappa take that crown
in the future though.
