Good discovery! The bug seems to be deeper i suspect, since Fritz 8 (i haven't analysed with 9 because i don't have it) evaluates black's position as slightly better -actually as almost drawish) even after Kg8 or Kh7. So i suspect Fritz 9 would evaluate Kg8 or Kh7 as around 0.38 so it plays Ne5 as this looks to Fritz as drawish too. That means it doesn't understand the position. What if you force the moves 1...Kh7 2.Rh1+ Kg6 3.Rg1+ Kf7 4.Rf1+ Ke6 +- Does Fritz 9 shows now a big advantage for black? If my suspicions are correct and with a comparison with F8 evaluation, i believe that even in this position that occured, Fritz 9 will believe that it is still a draw. So now Frans Morsch has to try to understand what is the "problem" behind this position, because as such position exists, there may be (many) others with the same bad behaviour for Fritz 9 and this is the actual problem..... After 1...Kh7 2.Rh1+ Kg6 3.Rg1+ Kf7 4.Rf1+ Ke6 +- [D]1n1r4/1p1n4/2p1k3/8/3B4/8/4K3/5R2 w - - 0 5 > >Michael
