I will definitively not get it, but DF has been the second toughest opponent to Naum 4.0 after Rybka. I believe that the final score might be in between Jeroen and Graham 21.5 - 18.5
There is actually one that have been closer. Zappa Mex II lost with the tiniest of margins: 19½-20½ against Naum 4. So third toughest opponent so far.
Are you planning to test the latest version of Thinker which should be even stronger than this one here:
Next up will be Naum 4.0 Q6600 - Deep Junior 8 Q6600.
Why match it against a weaker version of Deep-Junior when Tony already matched it up against Deep Junior 10 Q6600 . Did you already matched versus Rybka 3 256 MB Athlon 1200 MHz:?:
