Rybasov Gambit
8... Bg4!
Black has attacked White's queen.
9. f3?? isn't the best move for White in this position as Black can safely take the bishop on d5. The bishop on g4 can't be captured because after 10. fxg4?? Black will go 10... Qxe4! with a forced checkmate.
9. Qd3! is a much better option. But after that the bishop on d5 will be captured.
So Black often chooses 9. Bf7! to remove their bishop from the danger with check. Black has to go 9... Kf8! and after 10. Qd3 Be2 11. Qh3 Qxe4 (or 11. Qg3 Nxe4) Black has got an overwhelming position.
