<H2>1. What is Deja Vu Chess Library?</H2>
   Deja Vu Chess Library is a CD-rom containing over 350,000 chess games in a 
FoxPro-based database, including a powerful search engine. It can be used as 
a standalone research database or in conjunction with most popular playing 
and chess processing programs. Macintosh and Windows versions are available.

<H2>2. What kind of games are included?</H2>
   A broad range of games from early analytical excursions by Greco to June 
1994. Most of the games are from professional chess events, but there are 
many examples of correspondence play (over 17,000) and about 10% of the 
collection is from Open and amateur events.

<H2>3. What kind of searches can be performed?</H2>
   Search by player, event, year, result, number of moves, specific sequences 
of moves, openings (both ECO codes and by name) and any and all combinations 
of these (including Boolean searches).

<H2>4. What programs work with DejaVu data?</H2>
   Virtually any program that accepts ASCII or PGN import, including 
ChessBase, Chess Assistant, NICbase, Zarkov, Hiarchs, Kasparov's Gambit, 
Chessmaster, Chess Genius 3, Gazebo, Bookup. Some programs require a 
conversion utility for PGN import. We supply a converter for ChessBase.

<H2>5. What export formats are supported?</H2>
   ASCII, PGN, Kasparov's Gambit, Figurine notation (USCF standard), Bookup
and FoxPro/dBase.

<H2>6. What hardware and software do I need?</H2>
   A CD-rom player, 3 Megs of available hard disk space, and 4 Megs of RAM, 
with Macintosh or Windows operating systems. You do not require FoxPro, since 
a runtime version is part of the Deja Vu application.

<H2>7. Suppose I want to put all the games on the hard disk, to increase speed?</H2>
   Then you need 210 megs free hard disk space, but it is more efficient just 
to copy the games you are interested in from the CD to the hard disk, and if 
you have a fast CD drive you can work from that.

<H2>8. Can games be imported?</H2>
   Not onto the CD, of course, but you can build an unlimited number of files 
on your hard disk or on floppies. We accept PGN format for import.

<H2>9. Are any of the games annotated? Can annotations be added?</H2>
   The games supplied on the CD are not annotated, as that would violate many 
copyright laws. Games can be annotated, 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.

<H2>10. How do the features of DejaVu compare with those of programs like ChessBase and Bookup?</H2>
   Deja Vu is a game collection, and you are paying for the games. The 
interface, with its search mechanisms, is free. It is intended to be used 
with other programs, not compete with them. The unique aspect of Deja Vu is 
that the games can be used with almost any program. You can even import them 
directly into Microsoft Word, Excel or Access. It is a true Windows/Mac 
program, with copy and paste functions via the clipboard. It does not have 
position search/compare features, built-in replay options, or other advanced 
chess playing functions. 

<H2>11. Suppose I now use one of those programs and switch to another later?</H2>
   That is one of the advantages of DejaVu. You can purchase whatever tools 
you like in the confidence that your game collection can still be used with 
both your old and new programs.

<H2>12. Is it copy protected?    </H2>
   Of course not. And our generous license permits you to use the program
and the games in any way you wish, other than simply repackaging 
the data and reselling it as a CD collection, or reselling substantial 
portions of it unaltered. But if you want to pull out games and publish them 
in books or magazines, or annotate them and sell them in some electronic 
format, that is fine. If you have a large hard disk on each of your machines, 
and want to copy the collection to both machines, that is also fine.

<H2>13. What about upgrades?</H2>
   We anticipate issuing an updated CD each year, with a very substantial 
number of new games and additional older games. The upgrade price will be 
under $100 per year, barring unforseen economic upheavals in the US economy. 
Right now we anticipate at least 100,000 additional games in the 1995 disk, 
which will be available in the summer of 1995. We will also include a new 
interface with many new features.

<H2>14. So why buy it now?</H2>
   You get the first version right away, and the upgrade path will be cheaper 
than buying version 2.0 as a standalone.

<H2>15. What about updates between version upgrades?</H2>
   They are free, and sent automatically to all registered users.

<H2>16. So how much does it cost?</H2>
   List price is $349. Resellers may adjust the price at their discretion.

<H2>17. Where do I get it.</H2>
   We work through most major resellers, including the USCF(New York), Chessco
(Iowa), and CB Software (London). You can also order direct from Chessworks 
Unlimited at 1-800-700-1242, or via fax (415) 712-0720 or via Internet 
(chesswks@hooked.net or Chessworks@aol.com.

<H2>18. What about technical support?</H2>
   As with all Chessworks products, unlimited toll-free telephone support, 
and electronic support is available at the addresses listed above (#17). We 
usually answer the phone between 11 am and 11 pm Pacific Time (2 pm to 2 am 
Eastern Time, or 7 pm to 7 am GMT). We do prefer e-mail when feasible.

<H2>19. Where can I get my hands on a demo?</H2>
   Our FTP site has a full working demo, with only the Import function 
disabled, and including only a small set of games. 

   ftp.netcom.com in the directory ftp/pub/chesswks/DejaVuDemo

Use anonymous login, and provide your e-mail address when prompted for a 
password. Be patient! Netcom is infamous for its inability to handle a lot of
anonymous logins. That's one of the reasons we are moving to another provider
in the spring of 1995.<Br>

<H2>20. How do I keep my database up-to-date between releases?</H2>
   You can import PGN files, available freely on the net. We will be placing 
many games in our ftp site too. 

<H2>21. How much overlap is there between DejaVu and the one offered by Chess 
Assistant? </H2>
   Quite a lot, of course, but there are significant differences. For 
example, we have over 1800 Blackmar-Diemer gambits, they have about 50. We 
have better coverage in the 1920s and 30s, they are better in some other 
years. Obviously to the extent we have games they don't, they have games we 
don't, since each collection is about 350,000 games. In 1994 you may find 
that one collection better fits your needs than the other. In the future, I 
expect the collections may grow closer to each other. The most significant 
difference is probably the 10% amateur games that Deja Vu contains, since the 
Chess Assistant disk is more Grandmaster oriented. We make a detrmined effort 
to include large numbers of gambits and unorthodox openings in our collection.

<H2>22. Are ratings included?</H2>
   No. We plan to develop a companion database with ratings, and link them to 
the players. It is our belief that the ratings found in existing databases 
have too many errors, and are based on so many incompatible rating lists, 
that they have no value.

<H2>23. Who designed and implemented Deja Vu?</H2>
   National Master Eric Schiller designed the database project, which was 
implemented by John Crayton of J.H. Crayton & Associates.

<H2>24. Where can I get more answers?</H2>
   Just e-mail us. E-mail to chesswks@hooked.net is usually the fastest path.
