Here is the current SSDF list, modified like that:

   1 Fritz 7.0 256MB Athlon 1200 MHz         2741   30   -29   574   64%  2636
   2 Shredder 6.0 Paderb  256MB Athlon 1200  2727   34   -32   467   65%  2619
   3 Chess Tiger 14.0 CB 256MB Athlon 1200   2721   33   -32   487   63%  2627
   7 Junior 7.0  256MB  Athlon 1200 MHz      2689   29   -29   593   58%  2632
   8 Rebel Century 4.0 256MB Athlon 1200 MHz 2684   33   -32   475   63%  2586
   9 Hiarcs 8.0  256MB Athlon 1200 MHz       2671   28   -28   624   55%  2638
  11 Gandalf 4.32h  256MB Athlon 1200 MHz    2652   34   -33   430   54%  2624
  21 Crafty 18.12/CB 256MB  Athlon 1200 MHz  2613   30   -29   561   53%  2593
  29 Nimzo 8.0  128MB K6-2 450 MHz           2555   22   -22   984   50%  2554
  38 SOS  128MB  K6-2 450 MHz                2517   18   -19  1428   45%  2551
  40 Chessmaster 8000  128MB K6-2 450 MHz    2515   44   -45   251   45%  2548
  41 Goliath Light  128MB K6-2 450 MHz       2506   24   -24   857   42%  2564

I looks like Ruffian could join the SSDF Top-10 if it's 40/2h performance is
similar to 1+1. OTOH, it may miss the 10th place (of the non-modified
ranking)when DF7 and Tiger 15 join the list too. Currently Shredder 5.32 is 10th
with 2669.

Btw. I've just did my Quicktest (24 tactical pos.) with Ruffian 1.0.0 and it
ranks between Hiarcs 7.32 and The King 3.12d/sel.10, IOW among the best
combinators. This proves excellent search techniques IMO. It holds the 5th rank
in my results for P3/700 and Athlon@1.2 GHz each (which include F7 NoMMX and
various Nimzos on top ranks, and are usually more or less different from game
performance ratings).

Top 8 QT results from Athlon@1.2 GHz, 256 MB Hash:

		 F7 NoX	S.Hund**Ki312d	Nimzo8  Ruf100	Hia732	Fri7.8	CT14.0
------------------------------------------------------------------------------
         GUI	 H732	S.Hund	CM8000	F7	WB 426	F7	F7	F7
    version etc. NoMMX	(255)	Sel.10  SH.NCD	(128?)			(192)

  speed rating*  209	187	191	190	183	176	189	163
------------------------------------------------------------------------------
QUICKTEST RESULT 399	387	381	380	373	366	359	333

 *) the speed rating is dependant on the solving times
**) S.Hund = Donninger program similar to Nimzo 7.32/-8 (no compatible engine)
