I was surprised that Fritz6 saw b5!! in 36 sec. and Deep Fritz took 42 sec.! Depth of Search was 20 plies deep set at 25 plies max. You'ld think Deep Fritz should have seen it first, with it's improved endgame knowledge. Maybe it has to do with only having a single cpu? Don't know? However, I beat them both! I saw b5 almost instantly. But that was based on knowledge, no search required. I guess you'll have to take my word on that;) Thanks for these positions Sune, many are quite interesting!
