First of all, Hiarcs (or any other Chessbase product) does not use ANY 6-piece
tablebases at this time.

>(R+p vs. B+P)?

At the present time, this can't be generated by ANYONE. (With the possible
exception that Stiller did this one, but I don't think he did.)

I think the generator might be included with Hiarcs.  You can generate any
5-piece (Kxx vs. Kx) ending with it, provided you have enough RAM.  The 5-piece
endings with pawns require 512MB, and those without pawns can be built with
'only' 256MB (with some disk paging).

Alternatively, you can download all 5-piece endings (and some 6-piece) from Bob
Hyatt's FTP site.  The generator is also there, if it's not included on the
Hiarcs CD.
