hmmm... I am not sure if the two concepts really square. The thing is they don't see the exal table, and their candidate moves don't eval positions in 0.1 increments. So they cannot be sure if their weaker move will result in 0.1 or 1.0 advantage down the line. Maybe you are referring to playing off book continuations of known openings? Those kind of fit your comment. Though, those moves are heavily prepared before the games and advantage there is results of pre-game strategy, rather than a tactical decision to throw off/confuse the opponent. Anyway I think we are splitting hair at this stage
