The game can be found below. Stockfish and Komodo both play 6 Nd5, a move not found at the ChessBaseDataBase, but it can be found in the “Big Database” (https://www.365chess.com/opening.php?m=11&n=145265&ms=e4.e5.Bc4.Nf6.d3.Bc5.Nc3.O-O.Bg5.d6&ns= which contains games played by players of all levels. The CBDB contains mostly games played by titled and/or higher rater players. For what it’s worth, Fritz 17 @depth 27 would play 6 Qf3) 6…c6 7 Bxf6 Qxf6 8 Qxf6 gxf6 9 Nge2 a5 (9…b5 was played in the game Arnaudov vs Enchev below) 10 a3 (10. g4 was played in the game, Genzling vs Bjornsson, below)
