Maybe it's the best at faster time controls, but I'm not convinced it's best at
long time controls. I continue to have problems with it at long analysis times
(several hours) in infinite mode. The analysis dwindles to only two half-moves
output after awhile. Also the time between successive outputs is unpredictable
and a higher multiple than desired. Fruit 2.2.1 or Shredder 9.1 are much
friendlier for long analysis, at this point...
