Square Signatures?

I was reviewing some older forums of mine and I came across this one. It then occurred to me that "Harry the h-pawn" has become as well-known in contemporary chess culture as many players. Who was the original person to come up with "Harry the h-pawn" - was it GM @Ginger_GM (Simon Williams)? I nominate the h2 square in his honor. Does anyone else have any good "square signature" ideas?

Deep Blue should get e6. Deep Blue sacrificed a knight on e6, which was a dramatic piece sacrifice. That game was critical in 1997 becaues Deep blue and Kasparov were equal. Kasparov describes this piece sacrifice when describing his four most famous games in an video interview with the New Yorker, which is available on YouTube. The link is below, and the time in the video is 5 min 40s.

You've got to have Kasparov on there somewhere. Where do you think he belongs?
I agree, Kasparov should be included. Of course, one purpose of this forum is to convince ME - who goes where and why
Clearly, coming up with only one square is tough (for anyone) but there is really no "wrong" answer; I am curious to hear the reasoning given as to why ...
If I were to give Kasparov a square, I'd have to spend some thought on which square and why. Perhaps I'd give Kasparov the f5 square because of the 1980 (Baku) game between Garry Kasparov and Maia Chiburdanidze, where 18.Nf5 is an excellent Knight Outpost that rules over everything.
Probably I can think of a better Kasparov square/situation with more thought (but that was a REALLY nice place to plonk the Knight)
