How do I stop guessing in Minesweeper?

How do I stop guessing in Minesweeper? Avoid unecessary guesses. Instead of opening three squares in a row open the yellow squares first so you have time to react if the middle square is a mine. If you open the middle square you need to make another guess. The fourth strategy opens the blue square to eliminate the guess.
