is off, Sigma Chess will not think during its opponent's time. This

Sigma Chess tries to predict your next move and starts analyzing the resulting
position. In case you should happen to play the predicted move, Sigma Chess
can respond quickly and thus save time on its own clock.

option is on, Sigma Chess is non-deterministic, i.e. it will choose randomly
among equally good moves.
