is the fried liver good (going for the fork)

why isn't anyone answering me!

There are much more variations of defence in the Fried Liver rather than those of attack, I believe. Using Fried Liver may work against low rated players, but surely it is not the best decision to use it against more experienced ones.

I thought that it's specifically after 5..nxd5 that you can call it the fried liver and by then it's already bad for black. Perhaps you mean 4 ng5.

If so, I think it's good but also the most demanding of white's good options. I would rather learn 4 d4 or 4 d3

You can use the vicious Traxler counterattack to totally rip apart the fried liver.

4. Ng5 is NOT the Fried liver attack.

The Fried liver is specifically the knight sacrifice in this line:

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5? 6. Nxf7

Of course, 5. - Nxd5? is a silly mistake, and only beginners will play that.

Maybe the the 4. Ng5 move should get a catchy name, so people stop calling it by a name that it isn't. I suggest "Not Fried Liver".

No, it does not work anymore because they might play a move not in that video

Well, for starters, this is not the Fried Liver.  That is the main line Two Knights Defense and is equal.

The Fried Liver only occurs after the idiotic 5...Nxd5? By Black, after which 6.Nxf7 is the Fried Liver Attack.

4.d3 and 4.d4 are both stronger than 4.Ng5 because of 4...d5! 5.exd5 Na5! Which equalizes completely.

Honestly, as white in the two knights, I prefer 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.d3, where white usually can keep the extra pawn in they fend off the attack. I've had success at the 1900 level with this line. I say Ng5 is good from an objective standpoint, but it is pretty risky.

A pawn is a pawn. 4 Ng5 d5 5 exd5 Na5 and let black prove his compensation.
Most modern day grandmasters as black avoid to lose a pawn with 3...Bc5.
Many modern day grandmasters as white do not grab the pawn and develop 3...Nf6 4 d3.

Bd7 is bad for Black, the main-line Na5 is his best try but even there it doesn't completely "equalizes": what we have right there is an interesting position where Black has to prove his compensation and he has to be really direct and know his theory well if he doesn't want to have a lost endgame! Maybe it should end in a draw but in human practice both sides have something to play for and I believe the positions teach you a lot in Defense if you're White and in attack if you're black. I would play both sides but with a small preference to White as I'm very materialistic

I think the traxler is not that good because I used to play it (not on chess.com) and I did not know what to do after the bishop sacrifice if they just moved their king. in the video I watched they did not tell you

Fried liver happens after 6.Nxf7. Before that is some variation of the knight attack. The most common way to stop it is by not entering the fried liver line, and instead of recapturing the e5 pawn with the knight you play 5...Na5, which usually goes  6.Bb5+ c6 and follows 7.cxb6 bxc6.... and black is down a pawn but with compensation for better development, initiative and more active play. Which is kind of funny because white wants to go super aggressive and attack but ends up trying to defend the extra pawn.

The OG fried liver after 7...Ke6 white is usually better but  is playable for black, especially if you know what you're doing because if white doesn't play correct and let black equalize then black is a piece up.

The traxler is more of a trick than anything, there are variations where you can even take the bishop on f2. if white knows what you're doing then you're probably lost, but there's still some poison to it

Also worth mentioning some cool sidelines after 5.exd5 is the Ulvestad where you reply with 5...b5 attacking the bishop or the Fritz variation 5...Nd4 . They're not as good as 5...Na5 but  you can get your opponent off-guard and equalize or even get a better position if white misplays it.

the fried liver is usable in bughouse and crazy house and low rated players but thats about it

Hard to figure out what you're talking about. The fried liver is good, even according to the engines.

its only good in other variants

As I said, it's hard to figure out what you're talking about. I'm talking about the fried liver, not about other variants.

6. Nxf7 is the best or second best move according to the engines.

no, but an alexandrian liver sandwich is unreal you have to try it

isn't that like a sub sandwhich
