This move is the best as 4. Bb3 dxe4 5. fxe4 and white's kingside is awkward. Black must now play 4...Nxd5 as other moves signifies that they are down a pawn. However, 4...Qxd5 is just an obvious blunder that is only played to make jokes and memes. The best line according to Stockfish is 4...Nxd5 5. d3 Bc5 6. Bxd5 Qxd5 7. Nc3 Qe6 8. Qe2 Nc6 9.
