I had mentioned this a while back.  Some tables are indexed to retrieve 8 bit
scores, others require 16 bit scores.  It is hard to predict which is needed
prior to building the table.  On a couple, Eugene missed with his guess and we
had versions of egtb.cpp that used 8 bit when 16 bit was required.  It will fail
every time.  Try the latest Crafty.  If it fails, the files are corrupt.  If
not, you are just stuck until the commercial guys get the latest egtb.cpp code
so that the last batch of tables will work correctly...

The .tbs files were duplicates that were in the tbs directory also.  I have
cleaned this up...

One thing I would like to see is a little consistency from Vincent.  IE why is
he even asking about the Nalimov tables?  IE, in the past he has complained:

1.  That f***ing idiot Nalimov can't write code.

2.  Nalimov egtb code is "buggy"

So why would he want to use them?

And then he _always_ mentions his egtb generator that is faster, uses less
memory, does less I/O, compresses better, etc.  So why wouldn'e he use his own
stuff?

Also Eugene's generator is threaded, and he runs it on a numa box, so it can't
work.  :)
