Your pawns are all male?
Nothing in the image or title implies the gender of the pawn or that all pawns are the same gender though… they might be all female or mixed, none of the options are gender specific.
I never understood what the Rook was supposed to represent. Everything else has a rough analog to actual battle. But castle towers are notable non-mobile.
Originally, the rook symbolized a chariot. The Persian word rokh means chariot, and the corresponding pieces in Oriental chess games such as xiangqi and shogi have names meaning chariot. Persian War Chariots were heavily armoured, carrying a driver and at least one ranged-weapon bearer, such as an archer.
Modern ones are akin to siege towers is my take.
In German they’re called “Turm” which literally translates to tower…
I suppose siege towers would make sense, however I’ve never seen a chess set that didn’t have them look like a castle. (Which could be one reason they look like that, so castling actually produces a castle)
Pawns are all just temporarily embarrassed Queens.
How does a pawn become any of the others?
You cannot promote to King or Pawn. As such, your statement is wrong and i feel betrayed.
I’d love to watch someone try to do this at a tournament. Just swapping out their pawn for an extra King with a deadpan expression.
Oh, just like real life.
