I’d always wanted an excuse to use square focusing of theatre lanterns in a lighting design and Chess The Musical gave me a very good reason. All of the downstage specials were focused in a grid of two rows of five squares using 10 SL 15/32s from front of house. My hat is off to Martin Pretty of the Hexagon staff who did all of the hard work on Bridge 2 getting the SLs in place first time.
This kind of focus meant the cast had to be well forward (pretty much on the front edge) of the box to be lit and there was a distinct but tiny shadow at the edge if they moved sideways between boxes. So accuracy in hitting marks (and explaining them) was needed. But the effort was worth it with a lot of encouraging comments.
