We already have _every_ table of the pawnless varieties.  For two pawns, he
needs the 1-pawn
cases, correct.  However, my response to Uri was about a _seven_ piece ending he
had listed,
if I understood his post correctly.

You'd think that Eugene has the correct files or else he couldn't generate the
tables.  :)
