  min value     1  
  max value     500  
4.9.4.11 Pins
  parameter type     integer number  
  default value     100  
  min value     1  
  max value     500  
4.9.4.12 Bishop Pair
  parameter type     integer number

4.9.4.13 Chess Knowledge
  parameter type     integer number  
  default value     100  
  min value     1  
  max value     500  

Chess Knowledge above 100 will result in more accurate positional play but a lower search depth. Chess Knowledge below 100 will result in less accurate positional play but a higher search depth.

4.9.4.14 Attractiveness
  parameter type     integer number  
  default value     101  
  min value     1  
  max value     500  

Attractiveness above 100 will result in more spectacular play and values below 100 will result in more boring play.

4.9.4.15 Attacking
  parameter type     integer number  
  default value     100  
  min value     1  
  max value     500  

Attacking above 100 will result in more tactical positions on the board. Attacking below 100 will do the opposite (avoid tactics)

4.9.4.16 Strength of Play
  parameter type     integer number  
  default value     100  
  min value     1  
  max value     100  
4.9.4.17 Draw Contempt Factor
  parameter type     enumeration  
  default value     0.00  
  allowed values     -1.00  
       -0.50  
       -0.25  
       0.00  
       0.25  
       0.50  
       1.00  
       1.50  
4.9.4.18 Selective Search
  parameter type     integer number  
  default value     100  
  min value     1  
  max value     500  

Selective Search above 100 will result in faster search by aggressive pruning techniques. Selective Search below 100 will result in a slower search but search is more reliable.

4.9.4.19 Search Technique
  parameter type     enumeration  
  default value     NORMAL  
  allowed values     NORMAL  
       
       RISKY  
       Risky Search typically will speed-up the search
       with 15-20%. Risky Search takes a bit more risk
       than the default search and is almost without
       any negative side effect. You can safely set
       Rebel to this value.
       
       OVERNIGHT  
       Overnight Search is very useful for correspondence
       players or for people who often use a chess program
       for long analysis up to 24 hours or more. The
       problem with most chess programs (previous Rebels
       included) is that after some time (15-20 minutes)
       the search kind of blocks and becomes slow as a
       snail due to a full hash table. The result is
       that a new main-variation can take ages.
       
       Overnight Search solves this problem and you may
       expect better results in the end. Overnight
       Search will limit several extensions to
       reasonable margins as Overnight Search assumes
       that tactics (if present) will be found anyway.
       As a result Overnight Search typically searches
       3-4 plies deeper while you are sleeping. Also
       the hash table use by the program is tuned for
       this option.
       
       DEEP  
       Deep Search will look for deep tactics.
       Rebel most of the time will find a combination
       1 ply sooner.
       
       DEEPER  
       Deeper Search will look for deeper tactics. Rebel
       most of the time will find a combination 2 plies
       sooner.
       
       DEEPEST  
       Deepest Search will look for even more deep
       tactics. Rebel most of the time will find a
       combination 2-3 plies sooner.
