So are you saying the move of giving up ones Queen as Bobby did..its amazing he won? The article said he picked up several pieces by doing that..Stop..don’t have to answer..I’m talking out of my comprehension level. LOL
Sacrificing a Queen is extremely rare for obvious reasons...but Bobby was beyond mere mortals when facing the board. Not advised for anyone seeing only a normal number of moves ahead. But in principle, to view castling as a defensive maneuver is incorrect, or at least incomplete.
It joins the power of the rooks in a tremendous magnified force projection across a large swath of the board, most notably the center. It will often occur at the point that you or your opponent is prepared to launch a major offensive - a kill shot, or to get to the end of the game. It’s like waling off your enemy and covering your assault forces. It happens before you strike.
