all chess is empty and meaningless
Reminds me Saudi Arabia's Grand Mufti's "The game of chess is a waste of time..."
Logically fallacious, you are utilising a false analogy which is so far removed from the original premise as to be considered absurd. Stating that chess is empty and meaningless is not synonymous with saying that its a waste of time.
In Arabic language these words are same: meaningless = waste of time!
well let me think of a few very simple ways. you can hide a tablet in the bathroom and periodically check the moves there. you can use earphone spies and so and so on.
you can go Boris Ivanov and hide the tech in a huge pair of training shoes (sneakers to our American cousins)
thatsrather primitive way of cheating lol unless shoes smell awafully
when asked by an arbiter to remove them he claimed just that, that his socks were smelly and he would rather keep his training shoes on. He lost the game.
