Accelerated Dragon vs HyperAccelerated dragon

Sort:
Kapivarovskic

Does anyone know any good (preferably free) material - video or written - explaining the different subtleties and nuances between the accelerated and hyperAccelerated dragon?? I know they are similar and can transpose but I am not talking about the move order, I know that. But I was wondering what going for one or the other allows in terms of possibilities to explore in your advantage for both white and black that the other opening wouldn't allow?
