It is truth that part of the machines are deterministic but there are many versions of Fritz6(Fritz6a,Fritz6b,Fritz6c... and you need to check the right one to know) There was also another >game posted which ended in a win for black after move 23.It began with >1.e4 d5 2.exd5 h5 3.Bb5+ c6 4.dxc6 Nxc6 5.Nf3 g6 6.0-0 .Once again it is >impossible to see how fritz6 chooses 6.0-0 since 6.d4! is the move that is >actually played.It is intersting to note that many other software programs >also choose 6.d4 in this particular position.However the most shocking example >in my opinion is the game given the Title "THE MORNING DANCE" it is played >at a time control of Blitz in 30 for each side.It begins with >1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qe3 Nf6 5.Nc3 Bb4 6.Bd2 0-0 7.Bc4 Bxc3 >8.Bxc3 Nxe4 9.0-0-0 Nxc3 10.Qxc3 Qg5+ 11.Rd2 Qxg2 12.Bd5 Qf1+ 13.Rd1 Qxf2 >14.Nh3 Qf5 15.Rhf1 Qe5 16.Qc4 Qe3+ 17.Kb1 Qxh3??

(the same kind of results were also obtained for other programs >too numerousto list here). It proves nothing. It is known that the first version of Fritz7 was not good and this is the reason that they upgraded it.
