Brian Wall on Chess!




It's true, I did not ask permission to Brian Wall to publish his part, but I publish on this blog because it is very interesting ... I think! Comments are from Brian.

{This is what Zach played against Hartsook in a slow game. GM John Nunn in
SECRETS OF PRACTICAL PLAY and IM Pfren on the lively Latvian Chess.com thread
insist 3 Nc3 wins with no muss or fuss. Pfren even called the Latvian Gambit
"stupid". Pfren was interested in refuting the Gambit with a minimum of time
and energy. I get this tude a lot with Jack Young's Fishing Pole. They can't
enjoy the ideas, just get me out of here as soon as possible. IM Jeremy Silman
calls idiots who won't listen to how unsound their gambits are "rapists",
meaning they write meaner and meaner comments the more you refute their analysis.}
fxe4 4.Nxe5 d5 5.Qh5+ g6 6.Nxg6 hxg6 {Jack Woehr mentioned 6 ... Nf6 but David and I don't like this line}
7.Qxg6+ {7 Qxh8 looks dubious for Black but hordes of Latvian afficiandos, Hartsook
included, are willing to play this. I tried it out with Rybka 3 and the results
were interesting. It was very easy for White to get in trouble or lose any advantage. Very scary for White even if it wins.}
Ke7 {This was the subject of 1878 George Brunton Fraser analysis. David played 7
... Kd7, lost 4 pawns for a Bishop and the ensuing endgame. A nice performance
by Zach. I believe Clyde Nakamura prefers 7 ... Kd7 or cites analysis of those
who do. I don't know which move is better but I was trying to improve on the Bekkedahl-Hartsook game.}
8.d4 {On 8 d3 Bh6 is OK but 8 d4 Bh6 is not OK due to Qe5+ later %08DA}

Jesus Daniel SEGURA (1)




This is the first game played by a Latvian Gambit fan, Jesus Daniel Segura T. from Colombia. During this monthhe attended an open in Ortega. The opening was successful for him and his game is very interesting. The second one will be published in another post. Good job Jesus Daniel!

ANALYSIS LAT07-33

  After 1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qf7 6.Ne3 c6 7.d3 exd3 8.Bxd3 d5 9.O-O Bd6 (as we know, this is a critical position. Black has tried most of reasonable moves, but apart of 9..Bc5?!, only text move come close to be satisfactory). 10.Re1 Ne7 11.Nexd5 (initially first player tried 11.Nc4 which guaranteed some initiative, although Black may be able to pick his way through the minefield and draw, thus White attention has turned to this way of assaulting Black’s solid centre) 11..cxd5 12.Nb5


  White has translated his lead in development into an attack. Most opponents will not last long in such a position, but even if they know the best moves they will still stand worse. This is a highly tactical position and it is easy for Black to make fatal missteps 12..0-0 (moves as 12..Kd7??; 12..Qf6?; 12..Bxh2+? or 12..Bf4?! are not sufficient either) 13.Nxd6 Qxf2+ 14.Kh1 Bg4 15.Qd2 Qf6 (The exchange of Queens isn't good: 15…Qxd2 16.Bxd2 threatens Rxe7 and Nxb7, but the big point is White's lead in development and Black's weaknesses such as e6; also 15..Qh4 is answered by Strautins move 16.b4!, White prepares to bring his Bishop to the a1-a8 diagonal, whilst at the same time b4-b5 can be a useful resource – see analysis in previous article, by transposition -; and finally Destrebecq recommendation 15..Nbc6 is replied by 16.Qxf2 Rxf2 17.h3 Bh5 18.Nxb7 – analysis. Test move 15..Qf6 was first played in a game Downey-Melchor, cr. 2nd.. LG WCh., 1997) 16.Qg5 (another possibility is 16.Nxb7 Bf5 17.Qg5 Bxd3 18.Qxf6 Rxf6 19.cxd3 Ng6 20.Bg5 Rb6 21.Nd8 Nd7 22.Re8+Ngf8 23.Rf1 Nf6! =) 16..Nbc6 (and not 16..Qxg5?! as it was played in noted game) 17.Nxb7 (or 17.Qxf6 Rxf6 18.Nxb7 Ng6 – better than 18..Rb8 19.Nc5 Ng6 20.c3- 19.Bg5 Rf7 20.Nc5 Nb4 21.a3 Nxd3 22.cxd3 h6) 17..Qxg5 (now is more correct) 18.Bxg5 Ng6 19.Nd6 (it could be tested 19.Bxg6 hxg6 20.h3 according Stefan Bucker: e.g. 20...Bf5 21.Nd6 Rab8 22.c4 dxc4 23.Nxc4 or perhaps 20...Nb4 21.Re7 Nc6 22.Rc7 Rac8 23.Rxc8 Bxc8 24.Nd6 Bd7 25.Kg1 Rb8 26.b3 Rb6 27.c4, the doubled g-pawn is a handicap, any combined R+B attack on g7 would be almost fatal and pawn a2 is difficult to attack, a7-a5-a4 hardly possible. In spite of the opposite bishops White has substantial chances) 19..Nb4 20.h3 Nxd3 21.cxd3 Bf5 22.Rad1 (22.Nxf5 Rxf5 23.Be3 maybe is slight advantage as White looking  for an endgame where often Rook+Bishop is better than Rook+Knight. Also is possible to test 22.Rac1) 22..Rab8 23.b3 (or 23.Rf1 Bd7 24.Rxf8+ Nxf8 25.Rd2) 23..Bd7 24.Be3 a6?! (24..Rf6 25.Bc5 a6) 25.Rf1 (25.Bd4!) 25..Ne7 (probably is better 25..Rxf1+ 26.Rxf1 Bb5) 26.Bc5 Nf5 27.Rfe1 Rf6 28.Nxf5 Rxf5 29.g4 (29.Re7!? Rf7 30.Rde1) 29..Rf8 30.Kg2 Rc8 31.b4 Re8 and soon – move 42- game finished in draw Melchor-Trofimov, cr. e-mail, 6th. LG WCh. final, 2010/11


  This game has been of a great importance if it was not the Black has to worry about a knight sacrifice on d5 one move before!!: 10.Nexd5! cxd5 11.Nb5 and now 11..Qd7?; 11..Bf4?; 11..Bf8? or relatively best 11..Bc7 of a recent game is illustrative: 12.Re1+ Kd8 (I add 12..Kf8? 13.b3 with attack) 13. Bg5+ Nf6 14.Be4! (I. Terenin, 2011; 14.Bc4 looks promising, but disables c2-c4 option, so after 14..Be6 15.Bxd5 Bxd5 16.c4 Kc8 - or 16..Nbd7!? - 17.Bxf6 Bf3! etc. Melchor-Sakai, cr. e-mail, 5th. LG World Ch., sf. A, 2004/05, 1/2-1/2, 36 or 15.Rxe6!? Qxe6 16.Bxd5 Qe5 17.Bxb7+ Nbd7 etc. with a very complicated game for both players - you can continue analyzing this great line! -) 14..Re8 (14..Be6 15.c4 crushes Black center) 15.Bxd5 Rxe1+ 16.Qxe1 Bxh2+ 17.Kf1 Qe8 18.Qxe8+ Kxe8 19.Bxf6 gxf6 20.g3. Igor Terenin ask if Black can hold this position. First impression is that he can't due to much less active pieces and weakness of his kingside pawns.

   Well, according my own experience it’s reasonably easy to increase the advantage: So, 20..Bxg3 21.fxg3 Kd8 22.Rd1 Nd7 23.Kf2 (23.Kg2) 23..a5 24.c4 h6 25.Rd4 f5 26.Nd6 Kc7 27.Be6 Nb6 28.Bxc8 Nxc8 29.Nxf5 Ra6 30.Kf3 and White won a difficult ending in Melchor-Borrmann, cr. e-mail, LADAC thema Final, 2010/11

ANALYSIS LAT07-34

  After 1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qf7 6.Ne3 c6 7.d3 exd3 8.Bxd3 d5 9.O-O Bc5?! (it was always been the first line that was tested) 10.b4! (Stuart James, November 2005), we know is being a true massacre in last games. The key line, at the end of the article, is quoted in red

                                                           POSITION 10.b4!   

  This is the known new idea to fight against 9..Bc5 instead of "old" 10.Na4 rehabilitated after 10..Bd6 11.c4 Ne7 12.cxd5 cxd5 13.Nc3 0-0! (or 12.Nc3 0-0! 13.cxd5 cxd5).
  Now Black can take the pawn or decline it. The point is that if 10…Bxb4 11.Ncxd5 cxd5 12.Nxd5 seems to give White very dangerous, perhaps winning compensation as has been shown in many games so far. Thus, let's me considerer 10…Bd6 as the “best” defence for Black ("The life or death of this line" according Jeremy Silman point of view).

** 10…Bd6 and now:

A.1) 11.b5 Nf6! (11…Ne7 12.bxc6 bxc6 13.Nexd5! seems strong: 13…cxd5 - if 13...Nxd5 Silman give 14.Re1+ Kf8 15.Bc4 and now 15..Be6 16.Rxe6! and Nxd5 with a powerful attack A.M. - 14.Nb5 and now old Fritz8 gave 14...Be5!? 15.f4! Bxa1 16.Nd6+ Kf8 17.Nxf7 Kxf7 with complicated position so Black isn’t doing badly as far as material goes; Silman analyzes 18.Ba3 not a bad move, but I prefer 18.c4! and Black has still a playable position though a tough's one. American player also note 14..Qf6 15.Bb2 Qxb2 16.Nd6+ Kd7 17.Nxc8 but I don't see any thing !, after 17..Rxc8 yes indeed Black position is ugly but still playable, he has an extra piece only for one pawn !? Probably are betters 17.Rb1 Qf6 18.Ne4 or 17.Nf7!? Rf8 18.Qg4+ Ke8 19.Nd6+ Kd8 20.Nxc8 Nxc8 21.Rab1 - A.M.-) 12.bxc6 (12.Nf5 Bxf5 13.Bxf5 0-0 - A.M.-) 12...bxc6 13.Nexd5?! (I prefer any other move though Black will play soon the castle and get the equality - A.M.-) 13...cxd5! (13…Nxd5 14.Re1+ gives White more than enough for the sacrificed piece, Silman) and White have not anything.  

A.2) 11.Nexd5 cxd5 and now the order of the moves is very important, so we have the following possibilities:

  A.2.a) 12.Nb5 Bc7 (12...Bxb4?! of Rosenstielke-Koudelka, cr. e-mail 5th. LG World Ch. final, 2005/06 one of the first games with this variation, is very risky. Now 13.c3 a6 - 13...Bf8 14.Re1+ Kd8 15.Bc4! Nf6 16.Bg5 - 14.Qa4 axb5 15.Qxa8 Bd6 16.Re1+ Kf8 17.Ba3; but I suggest as very interesting 12...Qd7!? - A.M.-) 13.Re1+ Kf8 14.Nxc7 Qxc7 15.c4 Nd7 unclear.

  A.2.b) 12.Re1+ (best) 12...Ne7 and we are transposing to the next chapter under B.3; if instead Black retreat his King, he will have admit a powerful attack:
* 12...Kd8 13.Bc4 (or 13.Be4) 13...Nf6 14.Bxd5 Qh5 15.Bf4 Qxd1 16.Raxd1 Bxb4 17.Bxb7+ Nbd7 18.Bxa8 Bxc3 19.Re3 as Melchor-Paiva Moreira, cr. e-mail LADAC thema sf. 1, 2008
* 12...Kf8 13.Bc4 Nc6 (13...Nf6 14.Nxd5 Bxh2+ 15.Kxh2 Ng4+ 16.Qxg4! Bxg4 17.b5 Be6 18.Ba3+ Ke8 19.Rxe6+ Kd8 20.Be7+ - also 20.Rae1- 20...Kc8 21.Re4 with attack, Hiarcs10) 14.Nxd5 until here Rosenstielke-Rouzaud, cr. e-mail 5th. LG World Ch. final, 2005/06 another of the first games with 10.b4, and now besides of game's move 14...Nf6? 15.Nxf6+ Qxf6 16.Bb2 +-, is a bit better 14..Be6 15.b5 or 14...Rb8 15.Bb2 b5 16.Bb3 but with a clear advantage and dangerous initiative for White in both lines.

B.1) 11.Re1! is by far the most critical response:

CRITICAL POSITION

11…Ne7 12.Nexd5 cxd5 13.Nb5 0-0 14.Nxd6 Qxf2+ 15.Kh1 Bg4 16.Qd2 and now so both 16…Qxd2 17.Bxd2 and 16…Qh4 17.Bb2 are terrible, Black must to choose 16…Qf6 and paradoxically we have transposed to a very known line from another move order (9...Bd6 10.Re1 Ne7 11.Nexd5! cxd5 12.Nb5 0-0 13.Nxd6 Qxf2+ 14.Kh1 Bg4 15.Qd2 Qh4 with the Strautins' idea of 16.b4! preparing to bring his bishop to the a1-h8 diagonal, whilst at the same time b4-b5 can be a useful resource) 17.Qg5! where Black’s getting stomped. Some examples:

  B.1.a) 17…Qxa1? 18.Qxg4 is simply winning for White, 18...Nbc6 (18..Qf6 19.Bg5 Qxd6 20.Bxe7 Re8 21.Bxh7+ Kxh7 22.Qh5+ Qh6 23.Qxe8 +- analysis by Viljams Strelis and also played in Sireta-Zaniratti, cr. e-mail 5th. LG World Ch. gr. F, 2002

  B.1.b) 17..Qxg5 18.Bxg5 Nec6 19.b5 Nb4 20.Be7 Rf2 21.Bh4! Fritz8 (or 21.Rf1 of Strautins, V)

  B.1.c) 17..Nbc6 - relatively best - 18.Qxg4 Qxd6 and now:

* 19.Re6 Qxb4 20.Qxb4 (20.Qh3 Ng6 21.Bg5 Qc3 with a small plus for Black (Borrmann-Gnirk, cr. ICCF thematic, 2000/01) 20...Nxb4 21.Rxe7 Nxd3 22.Ba3 Nf2+ 23.Kg1 Ng4 24.Rxb7 Rf7 is equal according Hiarcs10
* 19.Bd2 Bf7 (19...Ng6? 20.Re6 is worse) 20.Re6 Qc7 Melchor-Gnirk, cr. ICCF thematic, 2001/02 and now instead of game's move 21.b5?! Ne5 etc. I myself suggest 21.Rae1 Raf8 22.Bc3 with advantage.
* 19.Bb2 (the natural move and by far the most played at present) 19...Rf7 20.a3 (or 20.Qh3!? h6 21.a3) 20...Ng6 (if 20..Raf8 21.b5 Nb8 - 21...Nd8 22.a4 with idea Ba3- 22.Be5 Qd7 23.Qxd7 Nxd7 24.Bd6 Re8 25.Re6) 21.Re6 (also 21.Bf5!? Qf4 22.Be6 Qxg4 23.Bxg4 with advantage, played by John Elburg in two of his games) 21...Qf4 22.Qh5 with advantage was played three times with wins for White in all cases    

  Since all this is obviously unplayable for us, Latvian fanatics!, few years ago I myself had placed my hopes on Black’s last possibility: 11…Ne7 12.Nexd5 cxd5 13.Nb5 Bxb4 (instead of 13…0-0).

BLACK’S “LAST” HOPE

  White now has three ways to play the position:

  C.1.a) our hands slipped with 14.Nc7+ Kd8 15.Nxa8 Bxe1 16.Qxe1 Nbc6 when Black’s King will always be a source of discomfort, but White’s Knight is trapped and in many lines won’t get out alive. White’s chances are probably better, but it’s by no means clear how big that advantage will turn out to be. 17.Bg5 (17.Rb1 b6 18.a4 Bb7 19.Nxb6 axb6 20.Rxb6 Nc8 21.Rb1 and now, instead of 21...Nd6 which after 22.f3 leaves White with some compensation for the sacrificed piece according Jeremy Silman, I suggest 21..h6 avoiding Bg5+, or even 21..Re8 or 21..Ba8!? and Black is resolving their problems !). In this point, Silman only analyzes 17...Be6 proposing 18.Rb1!?, 18.Qe3!?, and 18.Bh4!?, but I would suggest 17...Bd7!? as more accurate and even totally best !. We see:

* 18.Rb1 h6 (18..Kc8?! is dangerous 19.Qe3 Nf5 20.Qf4 Be6 21.Qa6 menacing Ba6!) 19.Bxe7+ Qxe7 20.Qxe7+ Kxe7 21.Nc7 Kd6 22.Rxb7 Ne5 23.Bb5 Rc8 24.Bxd7 Kxd7 25.Na6+ Kd6 26.f4 Ng6
* 18.f3 h6 19.Bh4 g5 20.Bg3 Nf5 21.Nc7 Nxg3 22.Qxg3 Qf6 23.Re1 Nb4 24.Ne6+ Bxe6 25.Qd6+ Kc8 26.Qxb4 Rd8
Of course it will have many other lines all need to be analyzed though I don’t have the time to do the position justice – perhaps a reader will find something? ...).



  C.1.b) 14.Bd2 (!) (If 14.Nc7+ doesn’t lead to a serious advantage, then this simple and safe move should be enough.) 14…0-0 15.Bxb4 Nbc6 (15…Qxf2+?? 16.Kh1 leaves Black’s pieces hanging to threats like Bxe7 and/or Nc7. Silman) 16.Bxe7 Nxe7 17.Nc7 Rb8 18.Qe2 Nc6 (18...Ng6 is weaker 19.Nxd5 Bf5 20.Bc4 Kh8 21.Bb3 Rbe8 24.Qf3 Ne5 25.Qf4 Ng6 26.Qc7! –A.M.-) 19.Nxd5 Bf5 20.Bc4 Kh8 21.Ne3 and a forced series of moves has left White with a solid extra pawn, analysis by Silman again. After 21...Be6 22.Rad1 etc. this series of moves was tested in Melchor-Elburg, cr. e-mail, 2008, where White has a small advantage.

  But in this point, for instance after 21..Be6 22.Rad1 Rbe8 Hiarcs11 only give a slight advantage!; in fact, it must be better for White, but Black has chances to exchange the queenside pawns and draw the resulting 3 vs. 2 on the kingside situation as is usual in other lines as 10.Na4 Bd6 11.c4 Ne7 12.cxd5 cxd5 13.Nc3 0-0 or 3.Nxe5 Nf6 4.exf5. Another chance is in 20th. move if White try 20.Bxf5 Qxf5 21.Rad1 (Elburg-Melchor, cr. e-mail, 2008) and now not logical 21..Rbe8 so 22.Qxe8! ( I. Terenin ), if not 21...Qg6 or 21...Rbd8; perhaps even 19...Bd7!? preparing Rbe8 and personally I like for White this position than Silman’s previous one, but Black is solid and he has solved the worst of it.   


  C.1.c) 14.Rb1! played first time in Schmid-Domingo, FICGS e-mail, 2009 and quoted at http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1194567910/30 by Igor Terenin seems ruinous for Black so Rook on e1 is safe ( if not Nd6+). For instance, a game Melchor-Paiva Moreira, cr. e-mail, LADAC thematic Final, 2010 continued: 14..0-0 15.Rxb4 Qxf2+ 16.Kh1 Nbc6 17.Be3 Qf6 18.Rf4 +- (decisive advantage) 18..Qxf4 (18..Bf5 19.Bxf5 Nxf5 20.Bc5) 19.Bxf4 Rxf4 20.Nc7 Bg4 21.Bxh7+! Kh8 (21..Kxh7 22.Qd3+ Bf5 23.Qg3) 22.Qc1 Raf8 23.Bd3 etc. (1-0, 39 moves)

The Latvian gambit by Karlis Betins

From the book on the
KEMERI TOURNAMENT, 1937
Translation from Latvian to English by
Kon Grivainis/Val Zemitis

  The Latvian Gambit is an opening, where black after 1 e4 e5  2 Nf3 responds with 2...f5. This name to the opening was granted by FIDE because of the widespread research that was done in Latvia. Although in some variations positional type of play takes place, the Gambit has the chief characteristic that usually after a few moves a complicated, combinatory game starts. Often black manages to overcome his difficulties with various tactical swindles. Strategic considerations often disappear and tactics dominate. Often white is about to win, when black finds saving resources. The main disadvantage of the Gambit however are, first, that in many variations white has a considerably superior development, and second, that black cannot avoid variations that lead to a forced draw. But, as a draw by black is theoretically acceptable, the Gambit has its value.
   
What are the Gambit’s prospects? Will its only value be as an academic discussion by theoreticians, or will it be usable not only in correspondence play but also in over‑the‑board play? The answer will be forthcoming once the theory is better understood. Until that happens players may feel unwilling to commit themselves to unknown, risky variations and select instead the well known, safe openings, of which there is no shortage. So below I will introduce the reader with those finds that have come forth in the forty years since I commenced my research. That research I started because around year 1900 chess theoreticians, in particular the well known GM Dr S Tarrasch, were doubtful as to the manner in which the defense is to be organized in the Spanish game and its four knights variations, because the previous years results clearly showed that white were better of, and black’s choice of this opening was quite risky. That made me get started in searching for alternate defenses to the Spanish 2 ... Nc6. I did not like the Russian defense 2 ... Nf6 either, so my thoughts turned to 2...f5, which the available theory had rejected as insufficient and not worthwhile discussing. ‑ Here I should add, that the doubts about the solidness of the Spanish game proved baseless and it is as sound as ever.
  
The first research into 2 ...f5 was unpromising and only shear persistence  revealed that many of the prevalent objections were quite baseless. I also became aware that I had undertaken a big task indeed and to fathom all the complications required endless hours. When asked why I persisted, I can only make the comparison between going for a walk on a well paved road, as against  choosing a mountain path instead: many of us choose the latter. There is also the satisfaction of mastering a particularly difficult subject.

In practical play the gambit has shown good results to date, particularly in correspondence chess. This was particularly so in the correspondence match between the Swedish Chess Federation and the Seniors klub of Riga. The present chairman of the Latvian Chess Association prof. Dr Arv. Kalnins made the initial contact in 1934, on which the Swedish Chess Federation agreed to play 4 games (later a fifth one was added) with the white pieces, using different variations. Separate Stockholms klubs were chosen with well known Swedish masters in the forefront. The Seniors klub selected a committee to conduct the play. Under my leadership the klubs best players of prof. Dr. A. Kalnins, architect P Dreimanis, A Kannenbergs and composer Emils Melngailis went into battle. After 2 years play the result was surprising: Riga won three games, while the other two games were drawn! Of course, that does not mean that in the “Latvian Gambit” we have found the only answer to the moves 1 e4 e5 2 Nf3. On the contrary, I accept that that the solid 2 ... Nc6 is certainly not a worse answer. Of course, this cannot be finally answered by superficial comments or casual analysis in various publications, as is unfortunately happening.

 The following theoretical variations should by no means be considered as final, but rather as a try to establish the gambit as a serious and sound opening, presenting the main variations and tested lines on which the idea of the gambit rests in an organized manner.    



What did they think about LG

WHAT DID THEY THINK ABOUT THE LATVIAN GAMBIT  
    by Frantz Destrebecq

Its always an advantage to exchange the pawn of your King’s Bishop against the King’s pawn of your opponent; because by this way your King’s and your Queen’s pawn can occupy the center of the board. Moreover, in castling on the Kingside, your rook can come into the action from the beginning of the game. — Philidor, 1749.

According to K Betins, who I am inclined to believe, this move is perfectly playable. Actually, I don’t know any refutation of it. — Aaron Nimzowich.

This counter-attack is more violent than any other; therefore she is more easily refutable. — Reuben Fine

Practice showed that, despite of the first impression, the Latvian Gambit is not easy to refute, and in some cases Black even get good attacking chances. — Paul Keres

The Black counter-attack on the White center is premature and generally leaves White with a considerable advance of development. — Fred Reinfeld

Although the actual judgment of theory favors White, it is not easy for them to refute the opening of Black. — Alexei Suetin

 ... one of the most infamous openings of Chess. — Tim Harding

In the Latvian Gambit Black’s King lands on d8 60% of all games, on d7 25 %, and in the remaining 15% Black only loses in the endgame. — Kenneth Kirby

The best thing about the Latvian Gambit is that it is not as bad as its refutation. There are a couple of lines that give White a small advantage, but no more, — Jonny Hector


 ....if the LG is playable in correspondence chess, where the antagonists have access to theoretical works and further, where both White and Black are themselves experts on the opening, then how much more effective it will be over-the-board with the clock ticking away? The Latvian Gambit is the practical opening par excellence.”  — Tony Kosten

Betins, Karlis (also known as Behting), 1867-1943.
“Father of Latvian Chess”, he devoted almost his whole life in studying 2..f5, and found innumerable ideas about this opening. It is largely thanks to his efforts that the opening starting with 1e4 e5 2Nf3 f5 was renamed from “Greco Counter Gambit” to the “Latvian Gambit” by FIDE in 1937.
  He started publishing his analysis in 1909 in a St-Petersburg newspaper and published many articles subsequently. He was the leader of the Latvian players during the well known postal match between the clubs of Riga and Stockholm (1934-36). He also composed some studies. He died March 28. 1943.

Bilguer started to write it, and after his untimely death his work was completed by Von der Lasa. The first edition was published in 1843, then followed 7 other issues: the sixth was (1880) supervised by Schwede, the 7th (1891) by Schallop, and the eighth in 1916 by Schlechter. Finally two more revisions were published: by Mieses in 1921, and by Kmoch in 1929.

He was also a chess writer and chronicler. His book “Vom ersten Zug an auf Matt!” (published in 1957) was a great success. He was interested in the Latvian Gambit and introduced several new ideas, especially the important line 9.. c6! (around 1953) in the Keres variation (3Bc4 fxe4 4Nxe5 Qg5 5d4! etc.).

    For this index we have selected the names of the players who had some influence on the development of the LG, by writing a book or booklet, or as inventors of a variation, or as organizers of tournaments, etc. Especially we selected many players of the past. But of course many other contemporary players worked on the LG, or played it systematically (especially in corr. games); we can mention Harijs Gabrans, Eriks Krustkalns, Jurijs Arhipkins, Viljams Strelis (all latvians), Nikolaj Kampars, (USA), Ernst Grobe (Germany),  Wolfgang Stamer, Kurt Stummer (+), Fritz Borrmann (all germans), Alejandro Melchor (Spain), Thomas Svendsen (+,Switzerland), Graham Clarke (England), Sture Nyman (Sweden) etc.


 This list is not exhaustive and certainly we forgot many names!
