There might be a connection in terms of creativity. Chess requires creative thinking in terms of strategies, and novels and fiction books are all about creative storytelling. If Lisa is involved in all three, she might be using the creativity from one area in the others. For example, she could be writing a fictional story about a chess prodigy, or using the strategic thinking from chess to create interesting plot twists in her novels.
It's possible that Lisa is a chess player who gets inspiration from novels and fiction books. The complex strategies in chess can sometimes be related to the complex plots in novels. She might find parallels between the two and use that to improve her chess skills or just for enjoyment.
There could be. Maybe Lisa likes to read novels or fiction books about chess. In some novels, chess can be a central theme, like in 'The Queen's Gambit'. So if Lisa is into such things, there's a connection there.
