Harry Beltik ( Harry Melling)

Harry Beltik belongs to these traditional learners. He is also one of the best chess players in the state of Kentucky. Harry is very impressed by Beth’s talent and emerges in her life at her worst period. Melling has already played in Harry Potter in the role of Harry’s cousin Dudley Dursley. He also works on other films such as The Old Guard, The Devil All The Time and The Ballad of Buster Scruggs. On the small screen, he also appears in His Dark Materials and The War of the Worlds.

Beltik shows for his first time a notorious and a tough opponent who masters the secrets of the game that every player ignores. Despite that, he is such a weak prey in front of Beth.
When Harry and Beth live together in the latter half of the series, he decides to teach her all he knows about chess, which means in fact many things. He is afraid that Beth already knows everything that he tells her but she guarantees him that he learns many things from him. But viewers may probably think that she is not only referring to chess when she says so.
