B5 is advance, pawn takes is exchange.

actually is the engine does not understand long turn benefits. 

The gambit is for black.

Why isn't the "Midnight Gambit" in the chess com opening database? - Chess Forums - Chess.com

This forum topic contains the mainlines for advance and exchange.

I wonder how often you're gonna face this as Black, because many times they'll play Nf3 or Bf4
