Terra can be set to resign, offer draws and accept draw offers when the board situation is the right. In some theoretical draw situations like K vs K, K+B vs K, Terra will claim draw and just stop he game whatever value you have set to the draw option.
In order to resign, offer/accepting draws the following rules are followed by Terra.
Resign only if (resign=1 and ...):
If any of these rules are not fulfilled Terra will not resign
Rule 1: No draw offer/accept before move number x (40 right now)
Rule 2: No draw offers until y moves if one offer already
is made. (decent behaviour)
Rule 3: No draw offer/accept if it's a table base move
and material is ahead. (not yet implemented)
Rule 4: No draw offer/accpet if opponent time is very
short and mine is not
Rule 5: No draw offer/accept if any of the z previous
moves had a score above contempt
Rule 6: No draw offer if the computed move
have a score below s (decent behaviour)
Accept a draw offer only if:
The same rules as above except 2 and 6.
In Terra.ini there are three items that affects draws and resigning.
