As a 'returning to chess' player, I am slightly 'foggy' on some rules.
Currently playing long-distance with my son in Chicago (I'm in N.Y.)
I appreciated your site refreshing me on promotion of pawns. I was under
the belief that you could only 'promote' to a previously 'lost'
piece.
Now that I believe I understand that promotion can be to any piece other
than a pawn (not a piece) or a king, my question: How is the newly
promoted piece identified on a board? (lacking a replacement from
previously 'lost' pieces)
