Black to play

This is the late stages of a sharp variation in the Sicilian Najdorf, where white's last move was to retreat the bishop with Bg5-h4. In these positions, white aims for opening up blacks uncastled king by pushing the pawns g, f and e. The strongest effect is usually gained from pushing g2-g4-g5-g6, which forces black to weaken the light squares around the king (f7, g6 and e6). White also has ideas of f4-f5, e4-e5 and even sacrificing a knight on d5 or f5 to open blacks king. But it is blacks move and black has ideas too, right?
