Twilight loves playing chess, a new game that is rising popularity in Equestria. After playing several times with other ponies and Spike, she is confident in her ability as a chess player to play in the tournament in Canterlot after Rarity suggests it to her.

Before Twilight even embarks on this adventure, she says in her mind... Chess is only a game and it should never be taken literally.

Well, what would happen if she changes her mind after some "persuasion" from the game?

Oh, you may need to look at a layout of a chess board to know how this story works. :)
