after 10.Qf2 Qxf2+ 11.Kxf2 Ne7! 12.Nb5 Kd8 13.Bxf4 a6 14.Nc3 Nbc6 15.Rd1 white seems to have full compensation for the pawn.

Hi Brabo, yes that's the solution - great!

Without deep analysis of this line the engines are initially deterred by 10.Qf2 g3, which turns out to be great for white after 11.Qxf4.

Many thanks.

After 10.Qf2 g3 11.Qxf4 g2+ 12.Qxh4 gxh1(Q) black is a rook up but the engine coolly plays 13.Kf2 and doesn't see any rescue anymore for blacks second queen. The Kingsgambit is definitely not boring. I doubt very much that I would see all this in advance when playing unprepared a standard game.

This analysis has of course nothing anymore to do with OTB chess as I expect chance is close to 0% such lines can occur in normal practice.

I think 8 Nf5 can be nicely met by 8...Bxf5 9 exf5 Nc6, when 10 Bb5 is neutralized by 10...Kf8! - Black's King seems pretty safe here, and I don't think White's manages to make it to the Queenside. e.g. upon regaining the pawn with 11 Bxc6 (11 Qxg4 Nxd4) 11...bxc6 12 Qxg4, there is 12...h5 13 Qf3 and now the annoying sequence 13...fxg3 14 hxg3 Bxc1 15 Rxc1 Qg5!, when it looks like Black has a clear advantage either in the ending (after 16 Qf4 Qxf4 17 exf4) or the middlegame, where White's King looks to be in danger.

I have come across a problem for white that I cannot solve.

After 1.e4 e5 2.f4 exf4 3.Nf3 d6 4.d4 g5 5.g3 g4 6.Nh4 Bh6! the best I can do for white is 7.Nc3 Bg5 8.Ng2 f3 9.Nf4 h5 10.h4 Bf6 11.Be3 c6 12.Qd2 Bg7 13.O-O-O Ne7 =+

Any improvements for white?


Did you look at 8 Nf5 - ?

Your analysis in The Fascinating King's Gambit still holds in my opinion. But instead of 11.Ng3?, White should play 11.Qd2! intending 11...0-0 12.Qg5. When the queens are exchanged, there is not the slightest reason why Black's fewer pawn islands should be a factor. White's center may well be more important. A refutation of the King's Bishop Gambit this Black line is certainly not.


And I've now just blogged about that:

Jon, I'm not hugely familiar with the theory here. Did either of these two games challenge Shaw's analysis?


More that they added to it a bit, and they were my first games with the Quaade (tsmenace is my handle), so I thought I'd share them. The first one refers to Shaw page 169; the second to Shaw page 140 – 5...Nc6! etc is his line, and it's pretty equal.

I had a brief look at "1.  e4 e5 2.  f4 exf4 3.  Nf3 g5 4.  Bc4 Nc6 5.  O-O d6 6.  d4 h6 7.  c3 Bg7 8.  Qa4 Bd7 9.  Qb3 Na5 10.  Bxf7 Ke7 11.  Qa3 Kxf7 12.  Qxa5"

and one idea that popped up is 12...Kg6!?

Black has the bishop pair, a slight space advantage and better development, plus that White is left with the wrong bishop and pawns on c3+d4, which makes the light squares a potential long term weakness.

White has an extra centre pawn and potential counter-chances vs Black's king.


So, consolidating the king with 12...Kg6 should have a higher priority than trying to strike back with 12...c5.

I don't remember if we've discussed Kg6, but if it hasn't been mentioned before you could start a new thread for it, if you're interested?

Edit: After a closer look, I think 12...Kg6! is at least an edge for Black.
The good news is that Shaw's strange line vs my mainline is still okay for White. I prefer the Bd3-idea, but your Qd2-g5 also looks okay, though I'd prefer to have the queens on the board.


An interesting alternative to investigate earlier on might be 8...a6!?, which is ignored by Shaw, but seems to be favoured by Stockfish. The first point is that 9.d5 is met by 9...Bg4! and now if 10.dxc6?!, then b5! favours Black. If instead 10.Na3! b5! 11.Nxb5 axb5 12.Qxb5 Nge7 13.dxc6 Black ends up temporarily a pawn down, but with good compensation in terms of better placed pieces, open lines and - possibly soon to come - increased pressure on whites queen side pawns.

Just a joke. You guys have comminted a crime not quoting Gustaffson who was the first one who proposed this ...Kg6 novelty!


12...Kg6 is also given by Shaw (although he arrives at the position after 10...Kf8 instead of 10...Ke7, but after 11.Kxf7 that doesn´t change anything). He credits Gustafsson for the suggestion and states that it looks good after 13.Nbd2 Ne7, or 13.g3 fxg3 14.hxg3 c5!?

I can guarantee that the rumours are true! I was going through these lines here and suddenly when i hit upon ...Kg6 i had a memory flash and i was sure that i had seen this before somewhere.... So, i said to myself "let me check Gusti..." and i was right!
