After I bought WM-Paket 2001 (actually an old friend of mine bought it in Munich
for me), I asked Stefan  Meyer-Kahlen by e-mail about what to expect from Triple
Brain's analysis, as I was thinking of using it to analyse my own games. He told
me that if I had a Dual machine it would be better, because each engine could
use 1 processor. He did not mention any memory or hash tables issues (I think
that if someone is using a Dual he's got plenty of memory too...).

I used to run Triple Brain at my local FICS chess server, jogo.cex.org.br.
Scores were not bad, but unfortunately I gave up because of auto-232 and time
management (could not play games with fast time limits, because Triple Brain
would loose on time - I had to set a high increment, i.e., 7 seconds or more,
but no one wants to play an internet game with these increments! ). Most used
set-up that time was Shredder 5 + WbNimzo2000b:

Blitz: 2213 (RD 242.7) (win 2) (loose 1) (draw 0) total= 3 games
Standard: 2334 (RD 164.7) (win 12) (loose 0) (draw 2) total= 14 games

I think that now with a Dual machine, Shredder 7 + Ruffian would be a very tough
opponent, though I don't have any games to prove what I'm saying... :-(
