Virtual Chess 64

[Don Getkey]

Curious to see how my kids Nintendo 64 stacks up to some of the best PC chess
programs, I rented "Virtual Chess 64". N64 uses a 64-bit RISC CPU, clocking at
93.75mhz.

I was not impressed with "Virtual Chess 64", which I believe actually uses the
highly regarded VirtualChess II engine.

Graphics are bad, has virtually no game stats, other than clocks and an
evaluation bar/meter. It has "levels" of play, but it can not tell you any
time controls that go with the levels. Apparently they are seconds per move
based levels.

Level 3 allowed an average of 5 seconds per move, which is the setting I used
to test VC64 against several computers/platforms. The literature stated that
VC64 was able to search at an average rate of 3000nps. Surprisingly slow I
thought. A P90mhz PC would run VCll at around 7000nps, oh well, we shall see,
I thought.

Turns out VC64 is rather slow by todays PC chess standards. It actually uses
up time while still in it's book if that's any indication to you!

Not wanting to run the risk of losing to a kids video game in front of my two
sons, I chose to immediately bring out the "big gun" in the house, my
"Evergreen WinChip C6 200mhz MMX" PC. It was readily apparent that VC64 was
way out of it's league virtually nomatter what program I used!

CM5000,CM4000,CM3000,Rebel9,Rebel8,Rebel7,Rebel6,Rebel Decade
2.0,Fritz4,Fritz3,MCP5,GnuChess3.21 without opening book, SiberianChess, Arasan
3.5, and Necromancer, all had their way with VC64. All that is, except for
Microsoft Chess, which seems to be the worlds weakest chess program nomatter
how fast it runs.

Not wanting to demoralize the Nintendo fans in my house, I quickly explained
that the "test games" were not very fair, and that if I should use my aging
486SX/33mhz 12Mb RAM laptop, things would be far more fair; in fact as close to
equal platforms as can be had in this test.

My laptop generally runs most chess programs at around 3000nps, the same rate
as claimed by VC64.

Surprisingly, VC64 did do a little/lot better, giving Rebel9 some trouble
(again), managing a draw, and then losing to Rebel Decade 2.0, MCP5, and the
bookless GnuChess 3.21!

*I wonder why the Rebel clan seemed to have more difficulty handling VC64?
(Rebel9 200mhz, narrowly escaped a certain draw for the win in the previous set
of games.) VC64 reacted much more intuitively to the Rebel programs as well.

The first game you see below is actually the last one I played against VC64.
Kind of a, "let me show you kids what a real chess program can do game".

I kick started ye ole 386SX/16mhz 2.5Mb RAM PC, and lit the pilot light to
start MCP5. As each square began to light up in sequential left to right 1
second intervals, MCP5 was a go, and rates itself a respectable 2165 while
hitting only 700nps! (Game was drawn)

Conclusion? Virtual Chess 64 is for kids. However, even they thought it was
lacking in playable fun. Unfortunately, VC64 is but a shadow of it's former
self, i.e. the highly vaunted champion VirtualChess ll.

The Nintendo64 system though more closely related to Deep Blue than my PC, is
woefully lacking the speed to compete with anything faster than a 486SX/33mhz.
Well, unless your using that retard of chess programs, i.e., Microsoft Chess
a.k.a. "Ziggurat" that is.

1. e4 ... ;King's Pawn Opening. The King's Pawn
;opening move is both popular and
;logical. It controls the center, opens
;lines for both the Queen and the Bishop,
;and usually leads to an open game in
;which tactics, rather than slow
;maneuvering, predominates.
... e6 ;French Defense. The French Defense
;accepts a certain lack of mobility in
;exchange for resilience and solidity.
2. d4 ... ;French Defense / Normal. White must
;either now or later take this step:
;control of center, quick-opening lines.
... d5 ;French Defense / Classical 2.d4 d5. This
;is the strong point of the French
;Defense: capture it, bypass it, but
;don't ignore it!
3. Nc3 ... ;French Defense / Paulsen Variation.
... Bb4 ;French Defense / Winawer Variation. The
;popular Winawer Variation breaks up
;White's Queenside Pawns and leads to an
;unbalanced position with Black often
;castling long.
