Subject: Collector's Corner..Res-Deep Sjeng 1.8 VS.Saitek Sparc 4MB

Author: Steve B

Other Results are starting to trickle in for the Resurrection

in Germany they are reporting the Res-Fruit 05  leading against the Tasc R30
v2.5

in the UK another Res owner was reporting a lead in a match for the Res-Fruit 05
over another Tasc but the match seems to have been prematurely aborted


the Res has four engines so for  a change of pace i played a game pitting the
Res-Deep Sjeng 1.8 against the Saitek Sparc module

as is well known, the Sparc program was the last and strongest program written
by the now happily divorced husband and wife Spracklen programming team ..

the  Sparc was released in 1992 and ran on a 32 bit Risc Processor at 20 Mhz
with 1 MB Dram for the Hash Tables
a very rare upgrade was offered by Saitek to increase the Dram to 4MB
the  Sparc 1MB was rated 2225 Elo
there is no known rating for the Sparc 4MB but after some discussion with
knowledgeable collectors it appears the extra 3 Dram would increase the rating
to perhaps 2275

i tried a longer then usual(for me) time control of Game/90min  instead of
Game/30min to enable the extra Dram to come into play


Since the Sparc has to be considered the heavy underdog i gave it the white
pieces

in the game, the Sparc  was out of book by move 10 and the Res did not Castle
in the middle game the Sparc typically achieved ply counts of 7-8 with the Res
clocking in at 8-9

in the endgame the Sparc reached 9 ply and the Res 11

as it turned out , the game simplified into a Rook and Pawn endgame which should
have enabled the Sparc to make full use of its extra Ram

[D] 1n1r3r/1p2kp1p/p3pp2/1P5R/P1RP1BP1/7P/5P2/5K2 b - - 0 29

here the RES has a totally defensive position with all of its pieces on the back
rank while the Sparc has all of its pieces actively posted

..29.Rd7 30.Rh6 axb5 31.axb5 Rd5 32.Bxb8 Rxb8 33.Rc7+ Rd7 34.Rxd7+ Kxd7


[D] 1r6/1p1k1p1p/4pp1R/1P6/3P2P1/7P/5P2/5K2 w - - 0 35

35.Rxf6

i think the Sparc had a winning endgame  here but blows it with the wrong
capture
the Sparc thought for over 3 minutes wanting to play Rxh7 but then switches and
takes the F pawn
i cant help thinking that if it captured the H pawn creating a passed H  pawn
and sticking the Res with the doubled F pawns that the game would have ended as
a win for Sparky

Qd5    1/2-1/2

FINAL POSITION

[D] 7Q/8/5p1K/3qk3/6P1/8/8/8 w - - 0 56

both computers were returning PV's of less then .05 and both had ample clock
time so i called an end to the hostilities

even though i think the Sparc tossed away a potential win it played pretty good
for a program 13 years old
