Red Squares

Sort:
VULPES_VULPES

In this thread, when I say "red squares", I'm referring to a square on the chess board on which a chess piece gets captured.

So I thought of an interesting inquiry: what is the most common red square? Or in other words, on which square have pieces died the most often?

What do you think?

Probably d5 because of the Queen's Gambit.

I feel like we shoudl get a programmer to input a database of games and display the red squares by pictograph.

d4 because of all the Sicilians, plus so many open games.

Panzerkampfwagen_V

It's always d4 or d5.

The 4 center squares

d4, d5, e4, e5

Interesting. I'll try to do that as soon as I get the time. Hopefully tomorrow or some such.
