Are you sure about it?
Stefan told me that one of the things that he worked about was tactics.

My chessmaster6000(ss=10) needed some hours to avoid Qxb4
[D]r3rb1k/6p1/p2p3p/1ppb4/PB6/5NRP/1q3PP1/1B1QR1K1 b - - 0 1

I think that Fritz will also have problems with this position and my
only program that can avoid Qxb4 is Junior5.9 (and I guess that also Junior6a).

I do not see 6-0 in the games that you posted but only draws against Fritz6b and
Junior6a.
It is a disappointing result after the impressive result in WMCCC.
