I have to write a short essay on a movie called the seventh seal and I was wondering about a certain part that interested me and that would be where he is playing chess with death can any one give me some help with this... like what does it mean... and ect to it why does he keep doing it and so on please

He keeps doing because death is a spirit that is alive. Therefore, it's also in Harry Potter and the Deathly Hollow. It's means that he's playing with a spirit. Hope you got it and it's hard to explain.
