"You sit at the board and suddenly your heart leaps. Your hand trembles to pick up the piece and move it. But what chess teaches you is that you must sit there calmly and think about whether it's really a good idea and whether there are other, better ideas"

In this quote, Stanley Kubrick uses the game of chess as a metaphor for life. He explains the extreme emotions that can arise when faced with a decision, represented by the gamer's heart leaping and hand trembling. However, he also highlights the value of remaining calm and believing things through before making a move. This is a valuable lesson that chess teaches us - to carefully consider all alternatives and possible effects before taking action. It advises us to not let our emotions cloud our judgement and to constantly pursue the very best possible result. Kubrick's words serve as a pointer to approach life with a tactical and thoughtful mindset.
