King & Queen = Royalty.
Two bishops = Clergy
Two knights = Chivalry
Two rooks = ???
8 Pawns = Peasantry.
The 4 Rooks are placed on the corner of the board to weigh it down
so it does not fly way.
Try it.Set up the board for a game. Remove the 4 Rooks and the board
starts to float about the place.
That is why inlaid boards where invented to stop the board from floating about
when the Rooks were exchanged.
If any of you try the no Rooks experiment and your set drifts out the window
and is lost forever. Then you cannot sue me.
Cannot think of a term for Rooks (but I will).
I name my Rooks 'Pinky & Perky' if Pinkie can clearly see Perky after
10 moves then I know I'm doing OK in the opening.
See...You don't need opening books
...aim to get Pinkie shaking hands
with Perky on the d & e files. You will be OK.
I also have names for all my pawns, but that is for another thread on another day.
GM Jonathan Rowson calls his d-pawn 'Delroy' and often mentions him in print.
Check out 7 Dealdy Sins and his brilliant book Chess for Zebras.
All chess players are stark raving mad.
Going out will be back with a term for the Rooks...hopefully.
