It is true that Pick A Corner led to the choice of choosing a Whammy when it was first introduced, and said concept stayed in place for 11 months actually, from March 84 to February 85, when the left side of the board was reshuffled.
But as far as Go Back Two Spaces and Advance Two Spaces go, those squares never led to Whammies... on classic Press Your Luck.
When Whammy debuted in 2002, the first two episodes taped (they were aired toward the end of the first season run) actually had a bit a quirk to them. If you looked carefully, when the 2nd batch of Whammies was added to the board during Round 1, the Advance Two Spaces square at the bottom of the board could have actually led to a Whammy! The combination of squares DID pop up on the board, and stayed that way for the next round or two of spins before Advance was changed to a Whammy itself. And even though it was never actually hit in either of the two shows, the fact that it was possible probably caught someone's attention, which is why the order of the squares and Whammies was redone so that such a mistake wouldn't happen forevermore after that.
Strange, yes, but it's true. I can make a screengrab if you want.
