Does this have a name? It's like the Fried Liver but starts out as a scotch

I have never seen this one played before. It starts out as a Scotch, but then white sacs the knight like in a Fried Liver without the bishop. Does it have a name?

Beyond the Scotch opening, it's a mistake by White followed by a blunder by Black so wouldn't arise often enough to have a name.

Are you claiming the Fried Liver Attack itself is not a mistake then? That seems like what you are implying.

4 Ng5? Be7 leaves you a pawn down for no compensation.
6...d5 leaves you a piece down for no compensation.
6...Ke8?? is a blunder that runs into checkmate.

It's unsure what you're calling the "Fried Liver Attack". This is not a name of any known opening. The Nxf7 sacrifice in the Two Knights Defense is called "Fried liver", but without the "attack" part. And it's not a mistake, it's the best move or close enough.

I am not saying the opening in the original post is the Fried Liver. I am questioning the Fried Liver because it has a name, and the opening in the original post supposedly DOESN'T have a name. Couldn't we use the same logic and say that a move in the original post also could be part of an opening?

We would have to conclude that the Fried Liver Attack satisfies some standard qualification. If it is the knight attacking as you are suggesting with Nxf7, then why can't we also say Nxf7 in the original post also signifies an attack?

@6

"the opening in the original post supposed DOESN'T have a name" ++ Because it is just bad. "

"a move in the original post also could be part of an opening?" ++ No, because it is a sequence of mistakes.

Why can't Ng5 and Nxg7 be a sequence of "mistakes"? Are we splitting hairs saying it would at worst be a sequence of "inaccuracies"?

You don't need to go to the lengths of the Fried Liver Attack to find named openings to avoid. Fool's Mate is named after all. You could try naming your opening but it wouldn't catch on because it involves too many mistakes and blunders from both players.

As far as I'm aware there are no commonly named openings which include mistakes from both players but I'd be happy to be proven wrong.

Ng5 is one of the two best moves in the Two Knights defence even at Master level, see here. Nxg7 isn't a move in the Fried Liver Attack but if you mean Nxf7 then that is the best move and means that Black will have a difficult match if they're not well prepared. We can't consider either of these to be mistakes. It's even a bit of a stretch to call Ng5 an inaccuracy.

@8 In the original post 4 Ng5? loses a pawn for no compensation and 5 Nxf7? loses a piece for no compensation. Those are clearly mistakes. 6...Ke8?? is a blunder that runs into checkmate.

@10 In the Two Knights' Defense 4 Ng5 is playable, though most grandmasters prefer 4 d3 now.
In the Two Knights' Defense 5...Nxd5? is considered bad and 6 Nxf7 or 6 d4 are considered refutations of 5...Nxd5?

That was a typo, I meant Nf7. I wasn't replying to you. See I quoted the person I was replying to. Their train of logic is probably different than yours. I was trying to work with their logic. So, if YOU (no one else) is saying that they are not mistakes, then what is YOUR view on the original post?

This is not collective thought people. Each person comes to the table with their own thinking.

Where is the "compensation" in 1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Na5? Polerio.

@13

In the Polerio black has ample compensation: 6 Bb5+ c6 7 dxc6 bxc6 8 Be2/Bd3 and black drives back Ng5. White has a pawn, but black has better development, and open files and diagonals.
In their World Championship Match Carlsen played 3...Nf6 and Nepomniachtchi refrained from winning the pawn with 4 Ng5 and instead played the tame developing move 4 d3. So both Carlsen and Nepomniachtchi must have been of the opinion that black has enough compensation for the pawn.

Ok, thanks Optimissed. There is another thread I made where I have included a master game on what I am referring to as piece activity. Let me know if that is rubbish too.

When white play ng5....I've had that position exactly 244 times, I've won 159, lost 79, so a 65.2% win rate, lichess database shows after ng5, the most common response is h6, after knight sac, king takes, bishop check, ke8 is still the most played moved, even if black plays the best move which is kg6, you're only down 1.8pts on the engine, not even a full piece because of your position, it is however a bit of cheap trick only suitable for speed chess, definitely not rapid chess, and definitely not past intermediate level. It's just called a Scotch gambit trap.
