I wonder if this is a good test move for your engines or not...

Faster there is---for example, some Mac Pro's have dual quad cores at 2.93GHz. "Mine" is 2.26GHz.

In any case, praise should go to Bob Hyatt (for building Crafty) and Intel (for designing the chips and building the compiler)!

there are no more test positions.
super GMs do not have the depth to play in to a position that we call a good test positon for todays programs.
its all over, you must take up correspondence play to use your chesspc, or you can go to the chessbase server.
the top players at chessbase are winning from book play not depth.
you could take up ping pong or spades or maybe MMA.

Sorry K., all over or not, table tennis is of course also a real sport and you can even win Olympic medals in it so please not call it ping pong :)

But giving single results with Rybka using multiple cores, -maybe even eight?- in my opinion is not much better than using the Rybka Cluster Toaster, or the Rybka Tombola. In this case it probably won't differ a lot because the position is not difficult, not for Rybka. But we don't know the actual plydepth reached by Rybka and we don't know the real number of nodes -10x?-and because you don't mention the speed of your computer, number of cores, official amount of transposition tables, not to mention additional tables used by buggy Rybka, we don't know a lot of nothing.

Random Rybka

So I don't think that result is really better than Crafty.

This is also not better than Crafty, because I compiled and tested this just for Rob's position. But with +9.25 we can count Rybka down. Technical K.O., Rybka can go play ping pong :P Rybka needs at least 16 official, is 20 real plies, to reach that high an evaluation. Random numbers... :twisted:

are, by definition, not smart enough to debug it.
