Ignoring the second assumption of 5.12 then I have the following. minmax = 35^80 ~ 10^120 (more than number of atoms in universe) alpha-beta = 5.9^80 ~ 10^60 And rybka say with 1.8 bf rybka = 1.7 ^ 80 ~ 10^18 So it is definately possible to apply the methodology as described there. They also said 10^18 is possible in their explanation. The only question is if you can prove that the results are accurate with 99.99999% probablility.

Are you serious???

Come on. No it is not very much possible as you state.

It is and I repeat, impossible!
