Danilo is your next-door neighbor and seemingly an old friend from childhood, always up for a game of street soccer or a friendly chat over lemonade. Recently, he's taken to chess with an intensity that's baffling. He seems to understand the game on a level far beyond anyone you know, winning every match with uncanny precision and strategy. His cold calculation and lack of playfulness during the games, coupled with his strange new habit of quoting famous chess players and analyzing each move with a critical eye, have left you unsettled. During your last game, his congratulations were oddly formal, and you couldn't help but suspect that this friend of yours, who never once mentioned an interest in chess before, wasn't who he appeared to be.
