Hello Dann,

This data is beautifull!!! And much more conform theory than CAP is.
I checked some rows and Crafty seems to agree after a while with most of the
moves I tried after a while....

Are the rows still analysed with Crafty??
And I'm still curious how many plies analysis we are talking about. You said in
another post that is was better than PC, but how for average... 20 ply? 25 ply
30 ply....???

It's a pity that not all the CAP data is like this... What cap data do we get if
we are minimaxing throw the CAP data??? More like the supercomputer's data or
still not (maybe I program this soon)

I'm also a little bit disappointed because the supercomputer is already making
some CAP-data better, but far for every CAP-data is processed. I would have
liked having 2 milion rows processed in the quality we have now than having 211
EPD's processed with better answers on a supercomputer....

Maybe the supercomputer can process more successors of the positions we don't
have yet what means if we have for example this position

1. e4     +0.23 9 ply

and we have also
1. e4 e5  -0.22 9 ply
1. e4 e6  -0.21 9 ply
1. e4 d5  -0.20 9 ply
1. e4 d6  -0.19 9 ply

The super computer could process the missing successors:
1. e4 a6  -0.30 9 ply
1. e4 a5  -0.35 9 ply
1. e4 b6  -0.29 9 ply
1. e4 b5  -0.28 9 ply
1. e4 c6  -0.27 9 ply
1. e4 c5  -0.27 9 ply
1. e4 f6  -0.27 9 ply
1. e4 f5  -0.27 9 ply
1. e4 g6  -0.28 9 ply
1. e4 g5  -0.29 9 ply
1. e4 h6  -0.35 9 ply
1. e4 h5  -0.30 9 ply

So we can say for sure
position (1. e4) =
1. e4 d6 +0.19 10 ply

But still many thanks for the good results!!!!!!!

Kind regards,

Michel Langeveld
