Fundamental theorem of Investing:)

Every time you play a hand differently from the way you would have played it if you could see all your
opponents' cards, they gain; and every time you play your hand the same way you would have played it if
you could see all their cards, they lose. Conversely, every time opponents play their hands differently
from the way they would have if they could see all your cards, you gain; and every time they play their hands the same way they would have played if they could see all your cards, you lose.

at the same time, knowing about something is not the same as knowing something:)
