Yes, it was played on the same machine. Permanent Brain was *on* for
HIARCS. I don't know what HIARCS can or cannot do on the Macintosh...
Then again, I don't know what MacChess can or cannot do. This was not
meant as an encounter between equals. I bought HIARCS for its reputed
chess-smarts. I use MacChess because of its solid Macintosh look and
feel. HIARCS cost me $135 US plus. MacChess is free. HIARCS' hash table
size is fixed. MacChess enjoys the luxury of a 32MB transposition table.
In the eight games I've refereed between them, HIARCS has won three,
MacChess, none. Is the contest fair? I doubt that it *can* be fair. That
not the point of this exercise.

Wim has added nearly 8,000 moves to the opening book and more knowledge
of simple endings. One might have to play an awful lot of games
(perhaps) to notice. :-)
