Abstract
Local supersymmetry enhancement (LSE) is a formalism intended to identify information needed to describe microstates of supersymmetric black holes that are realised as brane systems. After illustrating the relationship between LSE and black-hole microstates with the F1-P system, we review two possible strategies to apply the LSE mechanism to get microstates of three-charge black holes. While the former leads to microstates that break the spherical symmetry of the horizon, microstates built from the latter preserve it, and are numerous enough to account for (at least) a finite fraction of the M2-M5-P black-hole entropy.
