Subject:  Chess-Playing Software
This area is undergoing major revision. Hopefully, enhanced reviews will
appear shortly. The strength of chess-playing software is highly
dependent on the hardware it runs on (all software discussed is for
programs available for MacOS are noted). Here is a method to approximate
strength differences for the same software running on different hardware
(source: _Computer Chess Reports_).
Computer Chess Reports now analyzes its software on a 486/66 or 486/50.
The 486 machines are expected to have a 256K cache, 386 a 64K cache and
386 sx no cache. Please note, most new, stronger programs require a 386
faster to run.
The following table to adjust ratings, appeared in the Volume 5, number 1
issue and was compiled by IM Larry Kaufman:
Pentium 90 MHz +65
Pentium 66 +50
Pentium 60 +40
486 DX 50(DX2-66) 0
486 DX4 100 MHz +20
486 DX2 50 MHz -25
486 DX/SX 33 -35
486 DX/SX 25 -60
486 SX 20 -80
386 DX 40 -80
386 DX 33 -95
386 DX 25 -120
386 SX 25 -140
386 SX 20 -160
386 SX 16 -180
286 16 MHz -180
286 12 MHz -205
286 10 MHz -245
286 8 MHz -265
8088 10 MHz -320
8088 8 MHz -340
8088 4.77 MHz -385
Processor "Chess MIP's"
8088 Speed in MHz divided by 19
80286, 1 wait state Speed in MHz divided by 8
80286, 0 wait states Speed in MHz divided by 6
80386, no cache memory Speed in MHz divided by 6
80386 with cache Speed in MHz divided by 4.7
80486 Speed in MHz divided by 2.3
(Note that math coprocessors--used before the 486--don't change the
since chess programs don't use floating point arithmetic at all.)
Now, if a program has a given rating on a 1 (Chess) MIP machine, this is
to adjust the rating for other MIP's (interpolate between points):
MIP: 0.25 0.5 1 1.5 2 3 4 6 8 12 16 24 32 48 64
Adj.: -180 -87 0 47 80 124 154 195 223 261 287 323 347 379 402
For example, a program running on a 10 MHz 8088 (0.5 MIP's and -87
will be about 272 USCF rating points weaker than the same program running
a 33 MHz 80386 (no cache: 5.5 MIP's and +185 points).

Subject:  Database Software
Chess databases store games and information about games, and can
and recall that information in a variety of ways. The "big four" of
databases are Chess Assistant, ChessBase, NICBase, and Bookup. You can
purchase data disks for each of these databases. NICBase and ChessBase
game-oriented,Chess Assistant is position or tree oriented and Bookup is
opening-oriented. Each has its strengths and weaknesses. A good (but
review of these programs was written by Eric Schiller and appeared in the
Sept. 1990 _Chess Life_. A more current review was written for the APCT,
Jon Edwards has volunteered his e-mail address for information:
email@example.com. At this time, I believe each of these
programs can interface with Fritz, Zarkov, HIARCS, and Chess Genius.
A saved postion can even be retrieved by ChessMaster 4000.
A saved postion (epd format) can even be retrieved by ChessMaster 4000.
The next version of ChessMaste 5000 is expected to be able to have a
integration with the database software. Reviews will be incorporated and
expanded here as I more fully
evaluate the programs.
Chessbase for Windows Chess Assistant now have an expanded review
and improved coverage. Deja Vu, Bookup, Nicbase and others will follow,
as available. Sincere thanks to both ICS and ChessBase USA for making
programs available for evaluation.

a standalone research database or in conjunction with most popular
and chess processing programs. Data is accessible from ChessBase,
Chess Assistant, Nicbase, Bookup and others. Macintosh and Windows
versions are available. Since this is in a Foxpro based database, Foxpro
or Visual Basic or Microsoft Access may also be used to develop your own
program or set up features you would like to use. A new version is
by the end of summer, a discounted upgrade to the new version will be
available. Yearly CD database upgrades are expected to be available at
less than $100 per year. National Master Eric Schiller designed the
database project, which was implemented by John Crayton of
J.H. Crayton & Associates.
The games supplied on the CD are not annotated. Games can be
if they are on your hard disk rather than the CD, by inserting comments
wherever you wish. All fields are editable, including the game itself,
which is stored in a Fox Pro memo field.
A broad range of games from early excursions by Greco to events of
