What is the Gajewski Gambit?

Hello, I'm trying to create a study on the Ruy Lopez and I've stumbled across the Gajewski Gambit, in the Chigorin Variation which is quite rare but extremely well-scoring for black.

What's the theory/main ideas for both sides and how should white refute it?

11. exd5 e4 12. Bxe4 Nxe4 13. Rxe4 Bb7 14. d3 Bxd5 15. Re1 Re8 16. Bf4 c5 17. Nbd2 This should do, In the resulting position it is hard for black to prove his compensation

What about 11. d4, declining the gambit?

11.d4 is good too but you have to be very precise to get an advantage
