In the ST:TNG episode, it was about a chess-like game, so even if you had all the information, still you could lose making no mistakes. But in real life, having all the relevant information is something that may be pretty uncommon. Specially when dealing with other people (players or not) making decisions, maybe in a future, maybe based/influenced or not on how you decided to move, or involving things that you don't know that you don't know. So you make the best decision based on the information you have available, and the end result may end poorly because things that you didn't know, or that didn't happen yet, or because unpredictable agents deciding and acting along the way, will develop.
