Abstract: I will review an exact AdS3/CFT2 duality, relating the tensionless string on AdS3 x S3 x T4 with minimal (k=1) NS-NS flux to the symmetric orbifold of T4. I will then explain how switching on R-R flux can be described, from the symmetric orbifold perspective, in terms of a dynamical spin chain, and how this picture is reflected on the worldsheet. The special features of the construction are likely to play also a role for the worldsheet description of the string dual of free N=4 SYM in D=4.
