I've been working through Polchinski on my own, and I have a really basic question. How would one derive equation 2.4.1? What does it even mean to write the stress tensor with the new indices z and z-bar? I thought this was obvious, but it isn't working out for me.

clarification: this is not a homework problem, and it is not for a class.

got it. wow, forgot to lower indices. there is nothing deep here, as i had originally suspected.
