Hi Mr. Uri Blass,
[translation from French by software]

I even come at the moment to read your message.
Just one precision: I did not declare that there was 100% of similarities
between Fruit and Rybka!
I just said that I noted many similarities...
Let me show you one of them:
I said that regularly Rybka and Fruit 2.1/Toga II 1.0 have the same evolution in
their discovery of the moves (PV). The difference is that Rybka find the serious
solutions quicker. For example:

[D]4r1k1/1b4pp/p7/1prP3q/2P1B3/5P2/P3Q2P/3RR2K w Bg6 - 0 1

After 3 proof, Rybka find cxb5, then it leaves it for Bg6 for a short moment and
returns to cxb5. At the end it choices Bg6 definitively.
Fruit 2.1/Toga II 1.0 have the same attitude, but they delay to find Bg6! ...
and there are many other examples.

My objective is not to criticize the n°1 Rybka, but my question is why so many
similarities. Other testers also noted some comparisons with their evaluations,
that I confirm in several positions.

Best regards,
Orlando
