I think the simplest way to do time management is to always assume that there
are X number of moves left in the game. So if you always assume there are 30
moves left in the game, you will always use 1/30th of the remaining time. If
there is an increment, add that to the time for each move. That way you will
play faster and faster as your time gets lower. There are probably better ways,
but more complicated, and this works fine.
const int moves_left = 30;
int GetTimeForMove () {
int time = (time_left / moves_left) + increment;
return time;
}
