King’s Gambit

It may be a good opening for mindless white attackers, but if they run into somebody that defends it well they will lose by a pawn in the end...actually I heard that Fischer discarded it as being "unsound".

ooopppsss....now I see, the people that like only are only good at baby chess....it only works well in short time controls.

Fischer isn't God, after he lost to Spassky he tried to refute the King's gambit, and failed. GB has something to say about this in his section on the "Fischer defence", which he dismisses with no praise: "This rather odd position offers White good attacking prospects."

Here is the Fisher Defence

The key move here is 3. ... d3 to stop  4. Ne5 (as in the Spassky win...) 
:

King's gambit is my favorite opening against 1. ... e5 as White. Against Fischer defense 3. ... d6, in particular, I've been playing 4.Qe2, for about 8 years. How can stupid questions arise as for "King's gambit - refuted/not refuted"? If it were an incorrect opening - it would have been proved hundreds times already, especially after the monster strong chess engines with 3100+ ELO appeared. But alas, even those 3100+ ELO monsters ARE NOT ABLE to prove that the King's gambit is incorrect or more than that - refuted

ddddd

Why is KG your favourite opening? I'm still unsure about it. Steinitz's consideration seems a sizeable black mark against it. How do you get over that one pawn advantage against players of your standard? I'm doing quite well in 15:10 at the 1400 level probably because beginners aren't used to it! Maybe it is still used by GMs because it has a similar shock value?

Why 4. Qe2? The standard 4. d4 seems better by "normal development" considerations (pawns on d and e control centre) and usual KG considerations - black bishop threatens to take back pawn.

Firstly, about the King's gambit in general - I am not Nakamura, and not Ivanchuk, and not Carlsen - but look - the three above mentioned super GMs play 2.f4, although not that often, but they do play 2.f4, and not only they (I mean the players above 2700+) - ask them, why they play King's gambit  Obviously because this opening is quite playable, even at the GMs' level.

Secondly, as for 4.Qe2 in the Fischer defense, - I do not assure that the queen move 4.Qe2 is better or worse than, say, the more popular 4.Bc4 or the main move 4.d4. I just want to say that as for the key position in the main line after 4.d4 g5 5.h4 g4 6.Ng1 Bh6 (6. ... Qf6 is of almost the same strength as 6. ... Bh6, and it may simply come to the same positions with different move order) - I prefer to play it as Black, not as White - that's just my personal impression, especially after having worked on that variation with Komodo 10 and Stockfish 8 (but even without help of strong chess engines, it had been quite clear to me that Black's position was more pleasant than White's in that line). I do not say that White loses after 6.Ng1 Bh6 - but it costs really much efforts for White to maintain more or less equilibrium, but of course tastes differ. Besides the 4.d4, 4.Bc4 and 4.Qe2, White also has a number of playable ways, for example 4.Nc3, 4.d3, or 4.b3.

The matter is that I not so seldom play the Pirc defense (1.e4 d6) as Black, and after 1.e4 d6, when my opponents (sometimes) play 2.f4, I am happy to respond with 2. ... e5, and in 9 of 10 games in this case the Fischer defense of the King's gambit arises. In other words, the Fischer defense is my main weapon as Black against the King's gambit, although I myself am very fond of playing the King's gambit as White. As for 4.Qe2, this is less studied, but really interesting to elaborate and to play as White. Just saying - in several blitz games, after 4.Qe2 g5 5.Qb5+ ... 6.Qxg5, - for very unclear reasons, Black resigned at once 

But of course, the idea of 4.Qe2 is not to eat up the pawn on g5 after the automatic 4. ... g5 

Looking that up in Burgess, I see it's the start of the "Modern Defence". Burgess says Black's idea is to return the pawn, killing white's initiative, then early castle and develop quickly.

Modern defence:

I didn't recognise your reference to "the Bird". I should study Burgess more .   He mentions "Bird's Opening" 1. f4, but let's discuss that in another thread... and stick to King's Gambit here. So... what would be a good response by White to the Modern defence? Could you publish your game here, NotSoStupidGM?

In the position after 4.ed Nf6, interesting are 5.Bc4 and 5.c4 (there are also 5.Bb5+ and 5.Nc3, but ..... tastes differ)

I imagine that the KG is not refutable without memorizing realms of theory so I don't bother. There are easier ways to get a playable game against this opening than just accepting and going into all those concrete positions.

In case White is prepared - he will get playable positions, regardless of whether Black knows the theory or not ...

I don't know if there's a refutation or not... I leave that question to the theoreticians. 

Uh... no?

Summary of thread so far: Posts #1 and #2 introduce KG, KGA, and KNGA. In #3 Logar presents plausible moves 3... for black. 3... d6 is main line.

Worth much pondering: #14:  Spassky vs Fischer 1-0. This illustrates the main line for White and Black, and caused Fischer to look for a better line for Black, with uncertain results, see #27: Fischer defence

#28 #3:  Shachfan presents interesting alternatives to main line Fischer defence, worth pondering by Experts, I suspect.  I'll play mainline for now, and try to remember to return N to home?! 

#33 introduces the Modern Defence. Take that pawn!?

Shorter summary: #26 Go Spassky! #33 Take that pawn!

Back to the questions: How should White proceed to attack after the Fischer defence?

You would think I would say, "It's bunkum?"  You apparently don't read my posts: I seldom do so without checking the claims out first.

According to the Opening Explorer, Black wins more master games than White, 43% vs 38% after 1 e4 e5 2 f4 exf4.  But after 3 Nf3 g5, it's now only a 1% advantage: 44% Black wins vs 43% White wins, while if Black plays 3...d6 (Bobby Fischer's recommendation in his famous article "The King's Gambit is Busted") the Black advantage rises to 50% vs 35%.  After 3...g5 there are several White variations where White wins more than Black.  Consequently, the databases show Black has more trouble if he plays moves that don't give the pawn back.

Every game I use King's gambit as white.

Love kings gambit I would recommend anyone to at least try it. In your puzzle Zlyphrr 5.Bc5 is a clear loss of tempo which black cannot afford. After this mistake white is clearly better.

Kings gambit can be fun, but I think 2...exf4 3.Nf3 d5 easily equalizes, and there are so many possible good ways of dealing with this gambit...
