Using chapter length to establish pacing. I like it when faster, more intense moments are in short chapters. I read faster this way as well. I also like when the author throws in longer, more descriptive chapters to help me establish the world in my head.

Currently reading the ToG series, & there were a series of one page chapters scattered throughout the book in the POV of a character who was possessed by a demon. Just a half page of rambling thoughts. I like how it captures the helplessness & swiftness of his suffering, only to be stopped short by the continuation of the plot.
