Traxler Counter Attack e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 Bc5 5. Nxf7 Bxf2+ 6. Kf1 Qe7


1) Chess.com computer at Level 10 plays 5. Nxf7. Theory recommends 5. Bxf7. Which line to follow in my game in tournaments? Please advice as I am confused now.

2) After analyzing the game with computer of chess.com it suggests 4. ... Bc5 as Blunder. The best move suggested by it is 4. ...  d5. Again confused as I know that this theory is Traxler Counter Attack and another is going for main line of Two Knights Defense. Kindly give your valuable suggestion. I played this game just now with play computer option of chess.com without login but as a guest. Waiting for your valuable answers. Thanks in advance
Bxf7+ is definitely the way to go in practice in my opinion. I have done quite a lot of analysis with stockfish on Nxf7 and am not at all sure it is better for white despite the computer evaluation early on.

Bxf7+ almost certainly is a lot better for white and is a lot simpler to learn which is important for a repertoire choice against an unusual line (most people won't have the guts to play Traxler!)
