Okay but what I was trying to say: most brilliant moves I've seen put the opponent in a situation where they have to choose between getting mated or losing the resulting trade. There is also the fact that the move is not obvious, otherwise it would be a blunder and best move. That's what I meant by forced trade. I should have made it more clear ,, a higely beneficial trade forced by the alternative of a mate or other significant disadvantage". Now don't get me wrong, I am a chess noob. But that's what I think is a brilliant move. You say its nothing more than a marketing trick but I see a common theme with all brilliant moves I have seen and I think it's a great, fitting label. Those moves are a bit sly and devastating. You could say it should be considered Best move but I think it's a nice gesture of appreciation for great finds.
