We introduce an infinite game characterizing various types of sigma-porosity for Souslin sets in terms of winning strategies. We use the game to prove and reprove some new and older inscribing theorems for sigma-ideals of sigma-porous type in locally compact metric spaces. This is based on a joint work with D. Preiss and M. Zelený. |
