In the aforementioned Albillo 01, Junior goes quickly to "depth=63" (or so) and then stops the search. Thus I concluded this is the max depth (and since we know that for Junior 'depth != ply', I suppose Junior's max depth is <60). Of course I may be jumping to conclusions. >I remember from looking at the selective search of Fritz that fritz can have >selective search depth of 50. IIRC the highest I saw was like 53 or 55, but never 60. So no "mate in 30" to be expected from Fritz... --- Shep
