4. Nxd4 or O-O


That's the Blackburne Shilling, not the Evans gambit. More than a few threads in the forums...

Ah, I should have clarified. I understand this was not Evans Gambit, I just stated that as reasoning for my opening moves. I have just seen Nd4 a lot instead of Bc5 so was just wondering what people thought about it.

Oh....Well if white doesn't know the trap and gets greedy, there's a world of hurt waiting for him. I think Nxd4 followed by castling is the usual plan though and black is just behind.

Nxd4 is better as O-O seems premature to do.
It ruins pawn structure after 5.Nxf3 6.gxf3
6.Qxf3 is a legal move I think...
Everything is good against Nd4, even Nxe5 but if u want to get an easy advantage :

Is white's Queen glued at d1 or something?
Both moves are good, but I prefer 4.Nxd4 exd4 5.0-0 with c2-c3 and grabbing the center to follow (#7). Black usually tries to keep the pawn at d4, but here 5...Bc5? isn't possible because of the mini-combo 6.Bxf7+ etc.
Exactly what I said, I just didn't mention the f7 trick, good to see I think like an IM

I will shock some people now as i did with my oponents
This is interesting, let me see what stockfish says

No, you can go to personal analysis and see the variants with evaluation, the premium member have access to guided analysis FMK
Looks like it transposes into the Traxler. It’s pretty much the line regardless if you take the bishop or not.

Not at all, this is completely different than the Traxler, in the Traxler, the bishop sac is with the black pieces, which matters except if White loses a tempo and the same position occurs. This is completely different

Also the opponent knight is not on f7 or g5, and not a lot is going on in terms of messiness of the board
It looks like a reversed Traxler, due to the sacrifice and knight check. It is completely different, I agree, but it has similar themes.
