I) GENERAL DESCRIPTIONS
Congratulations on the purchase of your NOVAG AQUAMARINE RISC II computer. You will be able to verify its
surprising strength and the wide range of functions and possibilities. If you are impatient to try out your machine we
suggest you read the “quick instructions” paragraph and play a few games at level 1.
Playing with the NOVAG AQUAMARINE RISC II is simple compared to other chess computers. In any case, we
recommend that you read the general instructions before starting a game. In the general instructions, each section is
independent of the others, so you don't have to read everything at once.
The NOVAG AQUAMARINE RISC II works with 6 alkaline batteries of 1.5V type (AA) that are not included with
the machine. To insert the batteries, open the compartment on the back of the machine and insert the batteries
according to the +/- signs. A fresh set of alkaline batteries provide approximately 60 hours of operation.
The adapter can be purchased separately from the machine with the importer's reference. Use only the adapter
specified for your machine, the use of another adapter invalidates the warranty.
Please connect the adapter to the mains before plugging in the machine.
The NOVAG AQUAMARINE RISC II has C-MOS type memory that retains the last position of the board. You must
make sure that the machine has batteries or that you have the adapter connected to the network, otherwise you will
lose the contents of the memory.
II) QUICK INSTRUCTIONS
1. Before you start playing, place the pieces in opening position (the white pieces on rows 1 and 2 and the black
pieces on rows 7 and 8) of the chessboard.
2. The switch is located on the upper right side of the machine.
3. Press the NEW GAME key and you will hear three beeps. “00:00” will appear on the screen. You can now
make your first move for White.
4. To set a specific game level, press the LEVEL key and then click on a square with a piece (for example square
A1 corresponds to level 1, A2 to level 2, etc.). If you do not adjust the level, the machine will play at the last
level it played before. (In this case, do not press the GO key mentioned below next.)
2

5. Once you have adjusted the game level, press the “GO” key to exit LEVEL mode. After this you can introduce
White's first move. Simply press the piece you are going to move and then the square you want to move it to.
At that very moment the machine starts up and responds more or less quickly depending on the level of play or
if it is in the opening book where you don't have to think.
Once the machine decides its move, a beep will be heard and some lights will come on that serve to indicate in
which row and in which column is the piece of the machine that it wants to be moved. After pressing this box,
the machine will mark the destination position in the same way. Consequently, your piece should be moved to
this new square by pressing it as usual. White will then play, proceeding as described above.
In the event that you want to go back a move, wait until it is your turn, press the TAKE BACK key and undo
the corresponding movement on the board following the steps indicated by the computer. In the event that a
capture has occurred, the computer will indicate on the screen which piece has to be replaced (you can see the
symbols of the pieces in the VERIFY section).
If you want to go back another movement, repeat the process by pressing the TAKE BACK key again.
III) GAME FEATURES
a) making a move
Simply press the piece you are going to move and then the square you want to move it to.
To castling, move the king first, skipping the square where the rook will remain. Then move the tower also by
pressing. When you promote a pawn, you will have to indicate the piece you wish to promote by pressing one of the
keys with the appropriate symbol. To cancel a wrong move before you finish entering it, press the CLEAR key.
b) eating a piece
If the computer indicates a move to a square that is occupied by an opponent's piece, it means that a capture will be
made. Press the piece that is going to capture, remove the piece to be eaten without pressing, and leave the eating
piece in its place by pressing the square. In case of eating on the go, do not forget to remove the eaten pawn.
c) Impossible and illegal movements
The NOVAG AQUAMARINE RISC II is programmed according to the international rules of chess and neither
accepts nor makes illegal moves. If you try to make an illegal move, the LCD will show “Err” and beeps will sound.
You can then make the correct move.
d) Castling
To castle, indicate only the movement of the King, which is the one that moves first by jumping one square, and then
introduce the movement of the Rook always pressing.
The NOVAG AQUAMARINE RISC II accepts and performs castling in suitable positions.
Note: It is illegal to castle when the king is in check or if it passes through a square that is
attacked by an opposing piece.
3

e) eat on the go
If you wish to capture en passo, you only have to indicate the square from which the pawn starts and to which it
goes, as if it were a normal movement. Always remember that you must remove the captured pawn from the board.
f) Promotion and subpromotion
When you are going to crown a piece, the message “Pro?” will appear on the LCD.
You will choose the piece you want to crown by pressing the key with the appropriate symbol. When the computer
crowns, it will show you the piece you have chosen on the screen.
If you didn't have time to see it, you can use the VERIFY key to find out the selected part.
g) Boards
The NOVAG AQUAMARINE RISC II announces a position that corresponds to tables with the LED marked
STALE.
h) Check and Checkmate
If the computer checks it, it will light the CHECK LED. In the event that it was checkmate, the MATE LED will
also light up.
If you check the computer, this will not be specified in any way.
The AQUAMARINE RISC II can announce dunks in 8 moves.
IV) SPECIAL FEATURES
1) NEW GAME key
By pressing the NEW GAME key, a new game will start. The previous game will be canceled and in the
computer's memory all the pieces will now be in the starting position.
Press the NEW GAME key each time you want to start a new game. The level of play will remain unchanged.

- 5-
2) LEVEL key
Your NOVAG AQUAMARINE RISC II has 7 game modes with 8 time controls each. To adjust the NOVAG in any
of the game modes press the LEVEL key. Each time you press it, you will advance to the next group (and you will
see on the LCD the symbols: tr = tournament level, At = set average time level, Sd = starting level at..., Fd = fixed
depth level , An = level of analysis, EA = level of new player, in = level of mate in ...). Once the game modality has
been decided, to program the level you must press the corresponding box with the help of a piece. (Mode and level
can be chosen directly by pressing the corresponding box: The column corresponds to the category and the row to the
level.)
Example: If you want to adjust the AT 4 level, press the LEVEL key repeatedly until the LCD shows
“At 1”, and press box B4 (to enter n° 4). On the LCD you will see “At 4” indicating the level that is
selected.
A faster alternative is to press the level key once and then the B4 box.
To indicate that the level selection operation has been completed, you must press the GO key.
You can change or just check the game level at any time during the game as long as it is your turn to play.
Note: When you turn off the computer, when you turn it back on the game level will have been maintained
invariable.
AS A GENERAL RULE, THE OLDER THE MACHINE HAS, THE BETTER IT WILL PLAY.

Description of the levels:
•Tournament Level Trl-Tr8:
For games with tournament time. All movements are predetermined at a fixed time (eg 40 movements in 120
minutes).
Level 8 is the strongest. If you exceed the determined time, you lose the game. This modality is the most natural
of the game, since it is the form normally used by chess players. If you consider yourself a good player it is
advised that you try level 1 or 2 at first.
•Average Time Level Established Atl-At8:
The NOVAG AQUAMARINE RISC II will make thoughtful plays with an average time equal to the one selected.
This modality is used to give a determined time to the machine to solve a problem.
•Starting Level In... Sdl-Sd8:
The machine has to finish the game in a previously established time. If this time is exceeded, the game is lost. The
clock counts down and will alert you with three beeps that the time has exceeded. In any case, if you want to
continue the game, you can do it out of time, but in the judgment of the machine you will have already lost. The
computer clock will continue to run. This is the only level in which the times appear on the screens at the
beginning of the game. (In the others it appears 00 00 00 00 ).
•Level Dc Depth Given Fdl-Fd8:
Important to prevent the machine from analyzing more than desired if it is intended to be weakened on purpose:
In this mode children can play using the first levels, such as FD1, FD2, etc. The computer will only search to a
certain depth.
•Analysis Level Anl-An8:
This category is the continuation of the previous one and in AN1 it deepens 9 half-plays. In AN8 he deepens 16
half-plays. As in this last level, in most of the positions, it would take an excessive amount of time, this
combination can be used as an infinite level: in this case, the play will be observed with the screen while the
machine thinks and it can be made to play by pressing the GO key.
•Eal-Ea8 New Player Level:
In this category the NOVAG AQUAMARINE RISC II will not think during the opponent's time. The computer
will think only a half move except when it comes to considering a capture attacked and defended by many pieces.
In this case, he will limit his reasoning to a specific number of half moves (a half move is a move of one color, for
example E2-E4,E7-E$ would be 2 half moves, one by White and one by White). black). All new player levels are
very quick to respond. If these levels are too difficult for a beginner, you can use the ones listed above; SD1, SD2
series, etc.
IF YOU HAVE DIFFICULTIES BEATING THE MACHINE, IT IS RECOMMENDED TO TRY AS SOON AS
POSSIBLE AT LEVEL SD1 OR TR1 IN COMBINATION WITH EASY AND RANDOM 4 MODES. In this way the
machine is weakened in a more "natural" way than in the SDI, SD2, etc. levels
Note: All levels can be changed with EASY (section 19). In this mode the computer does not
think while you do. In this way, another series of game levels lower than the previous ones are achieved.

3) Mate's Resolution function
The NOVAG AQUAMARINE RISC II can solve most mating problems in 8 moves, even those that require castling,
en passant capture, or promoting pawns. Press the NEW GAME key. Before starting the search for the mate, it is
advisable that you use the VERIFY key to check the position and make sure that the side that is going to make the
mate is the same one indicated on the LCD. If not, press the COLOR key to change sides.
To select the level of the checkmate in ... press the LEVEL key, then select the number of moves for the checkmate
with the boxes G1 to G8.
Press GO once to exit the function, and Go again to have the computer begin the search.
If the computer has not found a solution, the message “no nE” will appear on the LCD. In this case what happens is
that the solution DOES NOT EXIST and the problem is confused or the mate is done with more moves. (You can try
repeating the problem by increasing the level).
screens
While the NOVAG AQUAMARINE RISC II is searching, it will show you on the LCD the plays it is considering,
and a series of very useful information that will rotate as follows:
a) Time consumed.
b) First move considered in the main line.
c) Second movement of the main line.
d) Third movement of the main line.
e) Position evaluation, eg 9 99 means an advantage of 9.99 pawn units, if the - sign appears, it means that the
machine considers that your position is inferior.
f) Search depth (d 6 means it is searching up to 6 half moves).
g) Moves to be calculated (26 30 means that there are 26 moves out of the 30 possible ones still to be calculated,
with the search depth indicated above).
h) Time elapsed in this move
4) GO key
The GO key is used to enter a command or to exit the special functions SET UP/ VERIFY/ SET LEVEL/
AUTOPLAY/ SOLVE MATE.
These functions are explained in their respective paragraphs.
In addition, the GO key is used to:
•So that the NOVAG AQUAMARINE RISC II thinks the move for the side that has to move, even in REFEREE
mode.
•To interrupt the calculation of the move and force it to move immediately. In this case the machine will make
plays lower than the programmed level.
•To change color during the game. Wait until it is your turn to move and press the GO key. The computer will now
think the move for this color while you play the other side from now on.
•To make the computer play against itself. This can be of special interest at a certain point during a game, each
time you press the GO key the computer will think up the move for the color it's turn to move.
•To accept the HINT (see HINT).
•5) REFERENCE key
•In this mode, you turn NOVAG AQUAMARINE RISC II into a chess referee,checking the legality of moves
made on the board, the computer will not respond to yours

plays. This is very useful to make the machine play a certain opening: making the first movements, the machine is
directed in the desired direction and immediately afterwards it leaves the mode with the referee, thus ensuring that the
machine continues playing the line that it wants to study. .
The LCD will display "rEF off* when REFEREE mode is not engaged and "rEF on" when REFEREE mode is
engaged. The first press shows you the current status of the REFEREE. A second press (within two seconds after the
first press ) changes the function.
6) HINT key
The NOV AG AQUAMARINE RISC II can advise moves if you are not sure how to continue a game. When it is
your turn to play, press the HINT key and the computer will show you what it currently considers to be the best move
for the side that has to move, the move will be reflected on the LCD. You can accept the move that the machine shows
you by pressing the GO key at that moment, or make your own move regardless of what the LCD shows.
IF YOU USE THE HINT-GO SYSTEM, WHENEVER YOUR MOVE MATCHES THE ONE RECOMMENDED
BY THE MACHINE, YOU SHOULD MOVE YOUR PIECE WITHOUT PRESSING .
If you press the HINT key while the computer is thinking, it will show you on the LCD the best move calculated up
to then: AT HIGH LEVELS OR WHEN PROBLEMS ARE GIVEN TO THE MACHINE IT IS VERY
INTERESTING TO OBSERVE IN THIS WAY HOW THE MACHINE FOUND SUCCESSIVE PLAYS .
Press CLEAR to return to LCD rotating information. The recommended move is the best possible one calculated by
the NOVAG AQUAMARINE RISC II at the game level in which it is selected.
7) TRAINING key
This function is to help the new player:
Priiger step:
When it is your turn to move, press the TRAINING key and the computer will show you on the LCD the square of
the first piece that can make a legal move.
If you continue to press the TRAINING key, the NOVAG AQUAMARINE RISC II will teach you all pieces with at
least one legal move.
Second step:
Once you've decided on a part, press GO. If you now press the TRAINING key each press of this key will teach you
the squares to which that piece can make a legal move.
Third step:
Press the Go key to accept the play that the computer is advising you.
If what you want is to do a different movement, execute it in the usual way.
If you want to go back to Step 1, press CLEAR key to clear the LCD and press TRAINING to go back to Step 1.
8) TAKE BACK key
The NOVAG AQUAMARINE RISC II allows you to go back up to 138 half-moves to allow you to rectify what you
consider to be a bad play or poor line of play.
Wait for your turn to play. Press the TAKE BACK key and execute the movement indicated by the machine by
pressing the squares: the computer will guide you to undo the moves.

board with its initial in English. Press the box when depositing it.
Note: If you select the COLOR or SET UP modes to alter the position of the pieces, all moves made in the game up
to that point will be erased from the computer's memory. If there are no movements registered in the memory
of the machine, the LCD will reflect the message "bE G"
9) TRACE FORWARD key
This key is used to advance moves after using the TAKE BACK key or the RESTORE function. Each press of
TRACE FORWARD will “advance” one move in the computer's memory. When you have reached the last position
registered in memory, the LCD will show the message “En d”
10) COLOR key

b) Press: NEW GAME , CHANGE COLOR and GO :
The machine will make the opening for the white pieces.
The COLOR key can be pressed at any time during the game, switching sides, which leads to an illegal move as one
side will make two moves in a row. All movements recorded up to this moment will be deleted from the computer's
memory. It is recommended to press COLOR twice in succession when you want to reset the time counters to time the
solution of any problem. After exiting SET UP mode, you should choose the color to move by simply pressing the
COLOR key.
11) CLEAR/CLEAR BOARD key
This key has several uses:
-In SET UP mode clears the board of pieces.
-If there are messages on the LCD such as “Ran”, “Esy” etc. you can delete them by pressing this key.
-To exit this mode press the GO key.
12) VERIFY key

NOVAG will go back its move and make the next best move that it has evaluated, as long as it is not excessively bad.
This function is only activated if at least 1 move has been made.
17) EASY key
The NOVAG AQUAMARINE RISC II always uses the opponent's time to think about your answer, sometimes it
answers immediately (even when the move seems difficult) because it has guessed your move and has already thought
of your answer. To deactivate this benefit, press the EASY key. When you are in this mode, you will see “Esy on” on
the LCD and when you disconnect it, you will see “Esy off'. This key will toggle between the two modes each time
you press it. Using this key doubles the levels converting them into a lower category.

Note: You can use the additional function TRACE FORWARD to replay the entire game.
THIS IS VERY USEFUL TO OBSERVE A GAME OR POSITION THAT THE MACHINE HAS PLAYED IN
AUTOPLAY AT A VERY HIGH LEVEL. In this way you can observe plays of a high level without the need to wait.
19) RANDOM key
Every time you turn on the computer, the game style of the machine is to choose the move with the highest value (in
its internal calculations), once the opening has finished. In order to provide more variety to the games by pressing the
RANDOM key the computer will randomly choose a move from a list of possible moves with a relatively similar
evaluation. There are several levels of randomness (rAn 1/2/3/4). The “rAn 1” level is the least random and the one in
which the machine plays the best. Only in the event that you are repeatedly studying the same variant, it may be
interesting to use the RANDOM mode. It is advisable to remove the modality as soon as the machine makes a variant
with respect to the previous game.
TO PURPOSELY WEAKEN THE MACHINE USE RANDOM 4 together with the EASY key.
20) AUTOPLAY
The NOVAG AQUAMARINE RISC II can play against itself, this can be interesting to observe a whole game or for
the computer to analyze a problem all night putting a high level without getting boring waiting.
Press LEVEL AUTOPLAY and select the option you want, the LCD shows “Aut ”, “dEn” if it is in autoplay or
demo. The difference between the two is that in AUTOPLAY mode the computer stops when a game ends, while in
DEMO mode another game starts again.
Press GO and the NOVAG AQUAMARINE RISC II will start playing against itself on the level you are on. All the
movements are executed automatically by the computer and you can follow them by recording them on your board.

RESTORE followed by TRACE FORWARD.

D) Chess Rules
I. GENERAL INFORMATION
1. The two opponents play alternately. White always start.
2. With the exception of castling, a move consists of transferring a piece from one square to another that is empty or
occupied by an enemy piece.
3. The only piece that can jump over others is the knight. All the others must have a free path in their movements.
4. When a piece moves to a square occupied by another enemy, a capture occurs, so the latter will be withdrawn,
leaving the first in its place.
5. If, as a consequence of a certain movement, the king is attacked, in such a way that it could be captured in the
next move, then the king is said to be in check. Then there are only the following possibilities:
a. Move the king to an unattacked square.
b. Block the path that connects the enemy piece with the king.
c. Capture the piece that is attacking the king.
If none of these alternatives are possible then the king is in a checkmated position and the game is lost.
II INDIVIDUAL MOVEMENTS
1. KING
Except for castling, the king can move a single step in any direction. But the destination square cannot be attacked by
the enemy pieces.
Castling is the only move in which two pieces move:
a. First the king moves by jumping one square to the right or left.
b. Then the rook moves jumping over the king and leaving it in the square that the king jumped before.
Castling can only be done if the following conditions are met.
a. There is no piece between the king and the rook.
b. None of these empty squares are attacked by enemy pieces.
c. The king is not in check.
d. Neither the king nor the rook have moved since the game began.
2. ROOK
The rook moves vertically or horizontally in all directions and jumping over the squares you want if they are empty.
3. BISHOP
It moves similar to the rook but diagonally.
4. QUEEN
You can make the moves of the rook or the bishop as you wish.
5. KNIGHT
It moves making “L” shapes in any direction. It must skip any square that is around it and stay right on the following
ones observing the following condition: if the square of origin was black it must go to white and vice versa.
The squares around the original position can be occupied by other pieces since the knight is the only piece that can
jump over it.
6. PAWN
This is the only piece that can only move forward and that when it eats it does so differently from its movement. In
effect, he eats diagonally, moving a single square forward and to the right or left.
When you first move, you can skip one square but after that you only move one square at a time. AJ Hegar in the end
the pawn becomes any other piece the player wants except another king.
When a pawn has advanced three squares from its original position, if a second pawn from the opposite side advances
two squares, passing through the square attacked by the first pawn, the latter can capture the second and for all
purposes it acts as if the second pawn had moved. moved a single position staying attacked by the first.
This operation is called eating a! step.
III. TIPS AND TRICKS
-The value of the pieces depends on the position but in general it is considered that if the pawn is worth 1, then the
knight and the bishop are worth 3, the rook 5, and the queen 9.
-Try to control the center of the board and remove the pieces as soon as possible.
-Castle as soon as possible.
-Don't be discouraged by the contrary.
