Hi @juanmolina, brot This is precise and conclusive:
"But in general what is sought to give checkmate."
This is a compelling argument, the question is who will you give checkmate to?
The world system is undergoing great changes, I believe that there are things far beyond what one expects, beyond what one can see, that are defining what is happening and what will happen, and the common citizen has no idea about it.
This is what theorists call "the world order." It is an open secret.
The checkmate is always given by those who have the best technique and take advantage of the "oversights" of their opponent.
Thanks for your valuable comment, dear friend.
