Abstract:	We characterize dyadic little BMO via the boundedness of the tensor commutator with a single well-chosen dyadic shift. It is shown that several proof strategies work for this problem, both in the unweighted case and with Bloom weights. Moreover, we address the flexibility of one of our methods.
