I posted a query to this list, asking if anyone has had experience with
this chess computer, then listed info from the web site. I received the
computer last night, and here are my initial findings. I'll list the
info from the site again, with my comments after each one:
This luxury state-of-the-art chess computer will give you the feeling of
The cabinet, and dark squares are walnut, and the white squares are
The chess pieces are boxwood.
The Novag Citrine MODEL #1032 chess computer has the most recent state of
the art technology using a H8/300H RISC Processor.
A comment: On low skill levels, this computer plays an excellent game,
and the processor is very quick at coming up with surprising moves.
It has been specifically designed for the truly elite chess player.
The Novag Citrine is the most powerful, quickest thinking, highest rated,
and most elegant chess computer available in the world.
Comment: It is a very impressive looking chess board. It has a very
nice finish to the squares, and the Staunton pieces are just a touch
smaller than the chess set you got if you took the beginner's chess
course from Hadley. The bishops aren't as conically shaped as I would
like, although they are distinct, and it is a personal preference.
. Estimated rating of 2330 Elo
Comment: Well, after a bit of play, I now know what that indicates. It
will beat the snot out of you! Heh heh heh.
. 81 LED's - four in each corner of the squares on the chessboard
Comment: You can feel these LEDs, so you know where the squares are, and
a light probe will detect them. More on this in a bit.
. Wood chess board
. Chessboard chassis, and dark squares are walnut, and the white squares
. Chess pieces are boxwood
Comment: This is a nice chess set to leave sitting on a coffee table for
display. When a friend came over and saw it on my desk, he said, "Wow!
That's a beautiful set! Really looks nice and classy!
. Chess board size is 11 3/4 inches x 11 3/4 inches
. Hand carved wooden chess pieces with 2.5" King
. The King measures 2 1/2 inches tall
. RISC Processor H8/300H
. Program Size 56K Byte ROM (Read-Only-Memory)
. RAM: 3K Byte RAM (Random-Access- Memory)
. System Clock Speed 20 MHz
. Power Consumption 450 mW max.
Comment: This computer does not operate on batteries, so you could not
play chess while traveling. Nor is it noisy enough to be heard in a car,
bus, or plane. It is for home use only, unfortunately.
. Opening Book appr. 24,000 halfmoves
Comment: It does have a very wide selection of book openings that it
selects at random, based on your first move if you are playing White, or
it will select one at random if it is playing White. It's first move is
not always the same.
. Separate detachable LCD screen has a six character alphanumeric display
with a chess clock, shows moves and a full range of game information,
also allows insight into the computer's thinking process and verifies
. Separate detachable LCD screen chassis measures 3 1/2 inches x 2 1/4
inches, and the screen measures 1 3/4 inch x 3/4 inch
Comment: The computer works the same whether this LCD unit is plugged in
or not, so I play without it. But it does have a very clear and sharp
display according to what the friend said about it.
. PC interface cable (included) allows the game to be followed on a
. Save and print games or connect to www.playwitharena.com which will
allow you to play UCI programs and convert games to pgn.
Comment: This is a serial port cable, not a USB. All of the information
on the LCD display will show up on the computer screen, along with a
board layout so that other people can see the game in progress if you
have a big screen. I haven't tried playing other chess engines through
this machine, and I'm not really into that sort of thing, so don't know
how often I will be using this capability of the machine.

. Auto-sensing of moves on sensory board detects the location of chess
Comments: The way it works is this: There is a magnet in the base of
each chess piece that will attract a switch that is positioned under each
of the board's squares. Pick up a piece, and the switch is released.
Place a piece on a square, and the switch is lifted. This is how the
computer keeps track of the board position. However, the magnets are not
strong enough to hold the pieces in place if you are scoping out your
move on the board. I solved this by placing strip magnet material with
adhesive backing, cut to the size of the squares, on each square of the
board. It was easy to center them using the 4 LEDs in each corner of the
squares as a guide. The men now stick to these strip magnets, and the
switches are still able to be activated or deactivated by placing or
removing pieces on the board as the game progresses. Playing against
this machine is just like playing over-the-board chess as far as piece
movement is concerned.
. Super strong chess programs capable of beating over 99% of all chess
Comment: I don't know about beating that percentage of players, but I do
know that it hasn't lost yet, and it was set to think about it's next
move for 5 seconds at the level we have been using. This is one of the
levels of casual play.
. 64 Levels for every type of player -
8 Tournament Levels: All moves are pre-set which have to be played within
a fixed time, i.e. 40 moves in 120 min.
8 Average Time Levels: Enter the average response time per move for the
8 Sudden Death Levels: If you or the computer exceed the specified time
control, the game will be declared lost.
8 Fixed Depth Levels: The computer will only compute up to the depth
8 Analytical Levels: These levels provide deeper searches for more
8 Novice Levels: 1 ply search with limited capture search.
8 Beginner Levels: 2 ply search with limited capture search.
8 Fixed Mate Levels: The computer will find the shortest mate up to the
. Solves problems up to Mate-in-8
. Mate Announcement up to Mate-in-8
. Depth search up to 18 half moves
Comment: As you can see, it has a very wide range of skill levels and
types of time controls. I did beat it on the first novice skill level,
and could see a marked difference between that one and the next novice
level, so you certainly can use this computer to sharpen your play by
selecting the right skill level for your ability.
. Setup mode allows you to enter a special sequence of moves, i.e. a
particular chess opening or moves you found in a chess book
I haven't tried this using a light probe as of yet, but plan to, mainly
out of curiosity.
. Switch sides with computer before or during a game
. Take back move function - take back up to 112 half moves
. Trace forward move function - use this function if you wish to trace
your moves forward again after having taken them back
Comment: This can be done using a light probe, and is not that hard to
keep track of as you take back or retrace moves.
. Force the computer to immediately make the best move it has found so
Comment: You should let it think for at least 5 seconds to come up with
a good move. Using a timer, I allowed it to think for 30 seconds, and it
played very strong chess.
. 2 player mode will referee 2 human players
Comment: It was fun playing against another human, using the computer as
a referee. We made a few illegal moves, and it showed our errors. The
timer also ran out when we played a sudden death game set to give each of
us 5 minutes to complete our game. I'm just not that fast of a player.
. Saves game in memory for future use
Comment: It will save a board position if you turn the power switch off
but leave the machine plugged in. It also saves the style of play you
set, as well as the skill level. However, if you unplug the machine, all
. Autoplay will make the computer play itself
Comment: I doubt if I will use this feature much, although it was fun to
see it play for both sides for a while on a high skill level, while we
tried to figure out what it's next move would be.
. Sound on/off
Comment: You can turn the beeps off for silent play, but, of course, as
I am blind, I rely on the beeps to play.
. Requires A/C adapter, included
. Includes Free 3 Year Classic Chess And Games .com Warranty
More comments on the men and board: To start a new game, just set the
pieces on their initial position, and the machine know that you are
starting a new game. You must use the pieces that came with the machine
on the sensory board in order for the computer to determine it's next
move. Right out of the box, a blind person cannot play this machine
without difficulty, as the pieces will move easily. The magnets I placed
onto the board solved this problem, though, as previously mentioned.
Part of the reason they move so easily is that they have felt bottoms.
Overall though, once modified slightly, and with a light probe handy just
in case you run into problems, this machine is very usable by a totally
blind person, and I think I'm going to be using it for a long time in the
future. One more note on the men is that, at least for now, I have
wrapped a trash bag twisty around each Black piece for tactile
