Structured Play

Set me free in a cube,
with gestures to promote,
I like a trim list,
perked up with promise,
give me strict instructions,
and with the others,
we will surely prove as bread.
With a list I am free,
who wants to rely on whim,
or beginner's luck,
or set those chips tumbling
amidst concerned looks,
from across the baize.
Going by gut is wild
when it works,
but free in a cube,
with a list,
I am free with
the weight of a mistake.
