Black already has both knights, a queen and a dark-squared bishop developed, and the light-squared one is ready to join the party. White has only the light-squared bishop developed since they wasted a ton of tempos by capturing material (and also deactivated their knight). Black can go 8...Bg4!, bringing a new piece to the attack. From now, there are a couple of variations: 9. Qd3 - the most natural move. After that White can go 9... Nxd5, and after 10. 0-0 Nb4 11. Qd2 Nbxc2 Black will regain the lost rook with a bonus. 9. Bf7+. White realises that after 9. Qd3 the bishop on d5 will be captured and removes his bishop with check. Here Black has the only move 9... Kf8!. Now White has to go 10. Qd3 but after 10... Be2! 11. Qh3 Qxe4 Black is winning. If White instead of 10. Qd3 decide to go 10. f3??, Black can go 10... Nxe4! with a totally won position. 9. f3?. Here Black can just simply go 9... Nxd5, and if White takes the bishop on g4, after 10... Qxe4 White will lose.
