Happy new year!

Now that you have made this step, it's time to start wondering if Rybka is
really doing something entirely different and new and has such a huge
evaluation, or if we should see Rybka as a Fruit-like engine but with some of
Fruit's weaknesses solved, and if it's really not doing anything really special.

How much stronger do you think Fruit would get with a better kingsafety and a
better extension system, and some evaluation holes plugged? As strong as Rybka?

And why is Rybka's endgame so spectacularly bad in some situtions (but fine in
others)? Is Vincents preprocessing theory correct? Was Vasik lazy regarding
those issues?

Something else entirely?

Aaah, the joy of questions to which we will probably never get a reliable answer
:)
