Sicilian exchange sacrifice

Today I played with a strong ukrainen player. I played him a few days ago with the same colour. We played a draw in a long game. I analysed the opening deeply and found an improvment. 

I decided to play a6 in the alapin to prevent the Bb5 pin, so my c6 knight can attack the d4 pawn.

I undermind his center with f6 to open the f-file and the long diagonal.  After exf6 Nxf6 I moved my knight to h5 to open the f-file and the long diagonal. In the same time I left the defense of the d5 pawn. He attackede the d5 pawn with Qb3, but missed a strong counterplay which led to a nice exchange sacrifice:
