If the time controls are X+Y where X is the initial total time of the game
(min)and Y the increment per move (sec) and you are using Y as an operator time,
then it should work approximately well because the increment is not supposed to
be used by the engine but by you.
The problem is when the operator time does not exist (computers are connected
together) and the increment is supposed to be used as thinking time. Tiger does
not know how to do that correctly.
Actually it always considers Y as operator time (positive or negative).
