*PRINT BOARD (Key H8) -  (immediate  action)

Pressing this key will send the current position to the interface.

35.

*GAME RATING (Ver/Set Key)

By using this feature you can ask your NOVAG SAPPHIRE II to rate your game according to the FIDE ELO rating
system.

Press the OPTION I/II key

 once

 and then press the Ver/Set key to obtain the  current rating.

The SAPPHIRE II will assign you with  1400 ELO points (shown on the LCD as 

[rt 1400]

) to start with and your rating

will be adjusted  whilst you are playing games.

To operate this function proceed as follows:

 

To exit the RATING function:  

Press the  GO key .

 

To reset the RATING function to 1400 ELO points:  

Press the  CLEAR key.

 

To rate a  game:  

Press the key with the Pawn symbol. A game can only be rated under the following conditions: the

SAPPHIRE II must have resigned or there must be a draw or mate condition, otherwise you will hear 3 beeps and the

[Error]

  sign will be displayed.

 

To offer a draw : 

Press the key with the Knight symbol. The SAPPHIRE II will only consider a draw based upon

your current rating and score. You can only claim a game as a draw position  after 20 moves have been played. The
LCD will show  

[rEJECt]

 if a  draw is not accepted.

 

Resign a game: 

Press the key with the Bishop symbol to ask the  SAPPHIRE II to rate this game as a losing game.

Note:

 To qualify for a game rating the  SAPPHIRE II must play one and only one side (black or white) and no moves

            to be  taken back are allowed.

The rating system used here is similar to the US Chess Federation two tiered formula. These first tier is suitable for new
players and enables rapid advancement.

The first tier formula:

Win:

(((PELO x G) + (OELO + 400)) ÷ (G + 1))

Draw:

(((PELO x G) - (OELO + 0)) ÷ (G + 1))

Loss:

(((PELO x G) + (OELO - 400)) ÷ ( G + 1))

New players only stay in this tier for the first 20 games then they move up to the second tier which will stop the dramatic
changes and stand to settle down to the actual rating.

The second tier formula:

Win:

(PELO - ((OELO - PELO) x  .04) + 16)

Draw:

(PELO - ((OELO - PELO) x  .04) + 0)

Loss:

(PELO - ((OELO - PELO) x  .04) - 16)

Note:

  "PELO":    

stands for Players ELO.

           "OELO":

stands for Opponents ELO and

           "G":

stands for number of games played

B.      OPTION II KEYS.

The following functions can be accessed by pressing OPTION-I/II

 twice

 followed by the appropriate key.  Pressing this key

again within 2 seconds will toggle between OPTION-I or OPTION-II functions.

36.

HASH TABLES (Key A1)

The default  mode is [

hASh

≡≡≡≡

] which means Hash Tables on.

Using Hash Tables is a technique which allows the computer to search much deeper into many positions, especially in the
end game.
