      Arasan 5.4     Arasan 6.0    Horizon beta
f5   378 seconds.   272 seconds      1 second
Bf5   40 seconds    140 seconds     30 seconds
f4   114 seconds     89 seconds      6 seconds

Most of the positions you have listed in the past have been too hard for
Horizon, but this time they seemed easy. AMD 1.67 GHz, 64 MB hash

Thanks for posting the positions I always save the ones Horizon can't find.
