  computer chess guy: It appears 16. Qc4 is losing (although this is not easy to see), but White could have escaped with 16. f4. After .. Bxf4 17. Qe2 Bxh2+ 18. Kxh2, Black's best is to aim for perpetual check with Qh4+. (16. d4 also appears =).

  An Englishman: Good Evening: The ultra-risky Ulvestad Variation (5...b5) isn't supposed to work, but if White doesn't find 6.Bf1,h6; 7.Nxf7,Kxf7; 8.dxc6,Bc5; 9.Be2 Black can win in excellent fashion. The defense 16.f4 is remarkable and hard to find even in pre-computer correspondence play.

  morfishine: Black launches a sizzling attack that leaves Burger ground down. Well done!
Dec-17-12  Balmo: I haven't done any computer analysis but can't white just take the knight on d5? Ok, he loses the queen but after ...bxh2, Kxh2, Qxd5 Nc3, White looks ok to me.
Dec-17-12  Dionysius1: I would have thought so - surely W has time to marshall his extra pieces against B's efforts to get a mating net with rook and k-side pawns to support his Q. No computer analysis available here either though.

  Abdel Irada: <Balmo>, <Dionysius1>: On 16. Qxd5, Bxh2; 17. Kxh2, Qxd5; 18. Nc3, Qxf3, we seem to reach one of those positions where, even in the absence of immediate mating threats, the defender can't make his material advantage count.

As a Traxler specialist, I used to look at a great many such lines, and almost always found that White's backward development, incoordination and exposed king gave Black a tremendous long-term practical positional edge.

In this case, given the placement of the white king and kingside pawn structure, it looks very hard to meet Black's plan of ...f5, ...f4 and ...Rf5.

Mind, I haven't looked at this in any really searching way, nor have I recourse to an engine. But based on what I did examine, I think White is lost in the variation you suggest.

Dec-17-12  Balmo: In the line discussed above, after 18...Qxf3, maybe White can try 19.a4 with the idea of Ra3? Looks like a good way to activate. Black does have decent compensation, but White can surely claim an advantage if he can untangle...

  Abdel Irada: <Balmo>: After 19. a4, Black has time for 19. ...Rd8, with the threat ...Rd4 followed by ...Rh4, and if White plays 20. Nb5 to prevent this, then the rook goes to d5 and h5 instead.

Your last sentence is true, but first White must untangle, and therein lies his Nemesis.

All of this is very familiar. At one time, in the early 1980s, I began to compose a book on the Traxler and the Marshall Attack (under the provisional title _Opening Fire_), and particularly in the former, positions like this were commonplace.

The vexation for White is that he simply never has time to organize effective counterplay. Most of his pieces are still sitting on their home squares on the queenside, and getting them activated before Black brings home the attack (or, in some lines, starts the kingside pawns rolling) turns out to be an insurmountable challenge.

Now, I can't claim certitude. There may be some line whereby White can find more effective play than I've seen for him so far. But his prospects don't seem sanguine.

Dec-17-12  MountainMatt: 14...Rb5??????? This is why I'm really starting to hate chess. What does this move accomplish, other than losing a perfectly good rook? I suppose that, since black won, it must be some ultra-masterful part of the grand winning plan, but I sure as &@#!@ don't see it.

I guess I'm just dumb.

  FSR: I still like my pun, "Frying Burger," better. This was no mere flip.
Dec-17-12  DrChopper: I think by doing Rb5, black gain a tempo for his combination. White must not give the chance for the rook to go on the g or h file, so he must waste some development to block it. By taking the rook, the queen must move again to be able to protect the g or h file, so he can't develop again. White wasted so many move for his queen that he didn't have any other pieces available to defend himself or to attack.

Not at all. 14...Rb5!? is a shocking move, and I have no idea whether it's best. Note that this was a correspondence game. Black was able to spend many hours analyzing his 14th move, and he probably did so; one doesn't lightly hang a rook. My guess is that he first analyzed 14...Nd5 15.d3 and was annoyed to see how White's queen on the fourth rank thwarted many of his attacking ideas (e.g. ...Nf4, ...Qh4, and ...Qg5+, which White can meet with Qg4). So he got the crazy idea of 14...Rb5, sacrificing a rook just to draw White's queen a little further away from the king-side, analyzed both moves at great length, and decided that 14...Rb5 was sound.

Great Game, Pun Meh

Dec-18-12  rwbean: If White plays 18. d3, then the next few moves are all forced on both sides: 18... Qg5 19. Bxf4 Bxf4 20. Rg1 Qh4 21. Rg3 Bxg3 22. Qxh4 Re1+ 23. Kg2 Bxh4. What's the assessment of that position?

  HeMateMe: I'd say it was a zwei burger, with all 'da fixins.
Dec-18-12  MountainMatt: <FSR> Thank you sir. I've been falling victim to some outrageous, successful sacrifices by my opponents lately, which is why seeing 14...Rb5 WIN rankled me so. *sigh* If only I were a Vulcan...

  Castleinthesky: Toasted Burger Buns?
Oct-12-13  rwbean: I looked at it some more with Stockfish 4 and was surprised.

14... Rb5 is actually a mistake because it only leads to a draw after best play by White, whereas 14... Qc8 leaves Black with an advantage (+1.33 after 41 ply: 14... Qc8 15. Kg2 Qf5 16. Rg1 Rfe8 17. d4 Qg6+ 18. Kf1 Qh5).

The right way to draw is with 16. d4 because 16. f4 as suggested in one of the lines by computer chess guy can be met by 16.... Nxf4 17.Kh1 Qh4 (-2.67 after 38 ply).

Then Black has an easy win in the game with 17... Qh4 instead of 17... Re8 which seems to lead to a drawn position with 18. d3 as I wrote above.

I'm not sure 7... h6 is the correct move; 7... Qd5 might be better.
