HARRY SCHNAPP TRIBUTE (4CPU)

Intel Xeon X5430x2 Octal
ChessGUI
256mb hash each core used
3-4-5 piece tablebases
Ponder off
HarrySchnapp.cgb book (limited to depth of 8 moves)
40 moves in 29 minutes repeating (adapted for the CCRL)
All engines 64-bit where available
4 cycles 36 rounds

Harry's generic opening books are among the finest (some would say the finest) for engine v engine testing.
This tournament is my tribute to Harry and a way of showing my appreciation for his efforts. You'll note that I'm using the final book that Harry produced for ChessGUI.
