We all know that the "center" comprises of the four squares that are in the very middle of the board - d4, d5, e4, e5.
Keeping this in mind, which are the central pawns, exactly, apart from the ones on the d and e files? Do they include the c, d, e and f pawns? Also, if a pawn not on a central file captures a piece and comes one file closer to the center, is that pawn a central one now, too?
