Hello Vael!

I am not going to include any 6-men Triblebases. Even though they are not the same as Nalimov, I still feel that if Ivan should have access to any kind of 6-men bases, then Rybka should also have access to 6-men Nalimov (which it doesn't and won't have).

Thanks for the settings!

I understand..but i see already a difference,these last IvanHoe's 50 serie are special build to use these new bases and play stronger!
You let also play Rybka against Houdine..and there are more engines who can't use end tablebases!
And they play against each other..i would prefer the best settings for each engine or what they can use to play better!

Always great to follow your live broadcasts!

The brand new Ivanhoe B50tA takes on Rybka 4,

Seems a rash decision: the current Ivans are not better than Rybka 4, even in Blitz...

I agree with you on the most part.

So therefore I will download the full 6-men Nalimov as well as the full 6-men Triplebases.

Happy now?

People want to see Ivanhoe, I give them Ivanhoe.

Always something, isn't it?

Fair enough...

One big difference full 6-men Nalimov = 1.2 TB and full 6-men Triplebases = 108GB so that's about 10 times smaller

JP.

[ernest]

full 6-men Triplebases = 108GB .

6-men ShredderBases are supposed to be 40 GB (but they are not out yet...)
