The Search depth submenu
This menu contains twelve predetermined lookahead
levels to choose from.
The following table describes these levels:
Midgame  Exact score  Win/loss/draw

6  14  16

12  18  20

20  22  24

24  26  28

The Midgame value is the lookahead in midgame positions,
the Exact score value is the stage (number of empty squares)
where WZebra determines the precise outcome of the game assuming
that both players play perfectly.
Finally, the Win/loss/draw value is the stage where WZebra
determines if it wins, loses or draws assuming perfect play.
In addition to these preset levels there are the following special settings:
 Userdefined level

Here you can define the playing level by giving the
Midgame, Exact score and Win/loss/draw parameters
as described above.
 Time dependent

This will make WZebra determine the lookahead itself using the settings
from the Time submenu.
 Solving (Win/Loss)

WZebra will determine who is winning by following all move sequences
to the end of the game.
Warning: This takes excessive amounts of time unless the number
of empty squares is less than 30.
The typical use of this setting is when analyzing a game, not when
actually playing against WZebra.
 Solving (exact)

WZebra will determine the exact score with perfect play from both sides.
This is even more timeconsuming than Solving (Win/Loss) and can
usually not be performed in reasonable time unless the number of empty
squares is at most 2728.
