Does Deep Fritz 10 do well against Rybka2.3.2amp?

[bigo]

I played a Six Game match between Deep Fritz 10 using the Fritz10 book
And Rybka2.3.2ampx64 using a 2600ctg book I created out of games of human Grandmaster 2600 and up. Both computers played on Dual Core Machines of similiar speed, Deep Fritz 10 won the Match 3 3.5 to 2.5
I know its only a few games but It looked like DeepFritz was simply positional outplaying Rybka.

There are a lot of things that could explain this:

- Giving too much hash to the engines.

- Ponder On.

- Wrong Setup

- Deep Fritz 10 got lucky.

There's no doubt Rybka 2.3.2a is stronger than Fritz 10.
