If you’re playing a game against someone and you want them to mess up, ask them how exactly they’re playing so well.
It seems just a insignificant thing to say while you’re in the middle of the game. But, in their mind something is happening. As soon as you ask that, their mind will process the question and they’ll overthink it.
They will start to fail more often and give you an advantage. If you’re not really a sports person, you can use this.
Of course, you can always actually try to improve your game. That’s better on the long run.
