1. e4 e5 2. Sf3 d5

Hi!

I've got an computer player which often plays 1. e4 e5 2. Sf3 d5

but I can't find an eco number for this opening. Its nearly philidor, but you know all "nearly" is in chess mostly just the same like "far away" 

but I find it astonishing that there seems to be no eco nr. I personally thougt there would be a number for every possible (central) move. 

what is the best answer? d3 generates problems with changing queens, exd5 e5-e4 forces moving away the knight, Nxe5 seems also not good, because after Qe2 the knigh has no good place to go. What do you say?

C40 Elephant gambit, the best and most popular move: 3. exd5 (ev=+0.8, SF9+, d=32).

Ok, didn´t know it! Nice. Interesting what comes next. Will have a look. Thank you! But one thing: what means SF9+, d=32 ?

SF9+ = Stockfish 9+ (chess engine), d = depth of the analysis in plies. U can use it here (for the analysis and preparation, not directly in your games, it will be considered as cheating) : https://www.chess.com/explorer

I would never cheat, I swear by mr. trump

no, relly, thats not my idea of playing the kings game. thank you for the explanation.

It's called Elephant gambit.

It's not correct, but positionally makes sense, following the modern treatment 3.exd5 Bd6.

GM Shaw claims an advantage for white after 4.d4 e4 5.Nfd2!?, but the position is certainly complex.

It's difficult to have doubts about white's advantage.

man just stop using your like you are presently doing in our game kid; and the way you talk you obviously know nothing; so pathetic

Black gives up a pawn for some to delay white's development (Becouse 4.Qe2 is forced if white doesn't want to give up the edge.

@Yigor @pfren I think it actually is difficult to find white's advantage. The engine can say whatever but I like black's bishop pair and centralized queen (hits a2 and g2 nicely), also white hasn't castled and has to be careful of Re8 and other ideas.

Hey, Mr Loudcolour: I´ve enough of your accusations! I lost a game against you, you lost a game against me. That´s live! You made a horrible mistake at move 16, I got a knight for free. And if you would do the analysis tool, you would see, that we both made a lot of smaller and greater mistakes. By the way: you needed much more time than I did, so, who had more time to cheat with another computerhelper, hm?

3. exd5 is the best move? May someone explain why 3. Nxe5 is inferior?

Just compare the two lines.

In the 3.Nxe5 line, it is white's turn to play, and the material is equal.

In the 3.exd5 line, same structure, but white has an extra pawn at d5, and it's Black's turn.

Which one do you prefer?

We already said that some prefer in the 3.exd5 line the move 5.Nd2 to 5.Ne5, but this has little to do with your question.

Thanks IM. I have the habit of Nxe5 coz it's effective against Latvian Gambit.

I only ever see it in blitz from weak players, so I don't know much about the opening. As far as I know, black's big trick is just a skewer on the e file, and as long as white avoids that he just much better.
