The Nightingale Gambit etc. (C70, C20, C60): Bombs

 The Nightingale Gambit etc. (C70, C20, C60): Bombs 

 

(by Yury V. Bukayev) 

 

 

In this our analytical investigation we’ll consider the enough strong attack which is common for some different opening systems (the Nightingale gambit – C70, the Woman Player’s Luck opening – C20 and the Popov variation – C60). 

 

Part 1: The Nightingale gambit (C70) 

 

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 b5 5.Bb3 Na5 6.Bxf7+!? [This variation of the Spanish game (Ruy Lopez opening, C70) has a traditional name “the Nightingale gambit”.] 6…Kxf7 7.Nxe5+ Ke7 8.Nf7!? Kxf7 9.Qh5+ g6! [9…Ke7?! 10.Qe5 Kf7 11.Qd5 Ke8 12.Qa8, and White has an advantage] 10.Qd5+ Kg7! 11.Qxa8 

 

1. 11…Nc6  

[The modern chess opening theory considers this line as “Black has a large advantage”, as the proof of a weakness of White’s move 8.Nf7.] 12.c3! AN [This move makes 8.Nf7 playable and, moreover, makes it enough good.] 12…Nf6! [12…Ne5 13.Qd5! (White plans to save the Queen by Qd5-d4-e3 if it’s necessary.) 13…Qf6 14.0-0! Ne7 15.Qd4 Nec6 16.Qe3 with a complicated fight.] 13.d3 [13.f3?! Ne4! 14.fe Qh4!; 13…Ne5 14.Ke2! with a complicated fight; the gambits 13.d4!? and 13.0-0!? are not bad, and the position is unclear in both cases] 13…Ne5! 14.Bg5! with the unclear position. Thus, the ways 14…h6 15.Bxf6+ Kxf6! 16.0-0! (or even 16.Ke2!?) and 14…Be7 15.Ke2!? lead to a complicated fight with unclear positions. [The “natural” move 14…Nd3?? is a mistake: 15.Ke2!. White wins. For example: 15…Ne5 16.f4! d6 (with the idea 17.fe?? Bg4!) 17.Bf6!. After 14…h6 15.Bf6 Kf6! 16.0-0! the “natural” move 16…Nd3? is a mistake too: 17.Qd5 Ne5 18.Qd4 Ke6 19.f4 Nf7 20.f5; 19...Nc6! 20.f5.] 

 

This defence no.1 in our analysis shows also that “the Nightingale gambit” isn’t a true gambit, in fact. Of course, White can choose another move instead of 8.Nf7 (analogously to the Queen’s gambit accepted where White can choose not 3.Qa4 Nc6 4.e3), but “the Nightingale gambit” isn’t a true gambit in this case too (analogously to 2.c4 after 1.d4 d5). Moreover, it isn’t even a pseudogambit: two minor pieces and one Rook with two pawns have only an approximately equal material value. 

In fact, we can receive a related true gambit (C70) in the Chase variation (3…a6 4.Ba4 b5 5.Bb3 Na5) after 6.d4 exd4!?: it is 7.Bxf7+?! AN. The name “the Chase variation” has a lot of synonyms (Taimanov variation, Norwegian variation, Norwegian defence, Wing variation, Accelerated counterthrust variation etc.), but it is the most correct of all used names, its best translation into Russian is “вариант «Погоня»”. [Thus, the name “the Accelerated counterthrust variation” isn’t very good, because the Bird’s defence 3…Nd4 is more accelerated Knight counterthrust and because the Exchange variation 3…a6 4.Bxc6 is also Black’s accelerated Pawn counterthrust in comparison with a-Pawn counterthrust in the Yanish gambit (Jaenisch gambit) 3…f5 4.Nc3 fxe4 5.Nxe4 a6!? AN, for example (here after 5…a6!? the position is unclear).] We suggest the name “the Chase First gambit” for 7.Bxf7+?! (its translation into Russian is “первый гамбит варианта «Погоня»”). Its consideration isn’t a topic of this investigation. 

Moreover, this defence no.1 in our analysis shows also the bright example of Wilhelm Steinitz’s fighting strong King in Open Games, and it is “centralized” (Ke1-e2) not as a result of an opponent’s check in some cases. 

  

2. 11…Qg5!? AN  

[Several other moves are possible too, but this move is the most dangerous for White besides 11…Nc6.]  

1. 12.Qxc8 Qxg2! 13.Qxd7+ Be7! 14.Rf1 Qxe4+! 15.Kd1 Qf3+! 16.Ke1 Qe4+! = 

B) 12.b4 Bb7! [12…Qg2? 13.Bb2 Kf7 (13…Nf6 14.Bf6!) 14.Qd5 with 15.Rf1 (White stands better).] 13.Bb2+  

B1) 13…Kf7 14.Qa7 Qxg2! 15.Rf1 Qxe4+! 16.Kd1 Qf3+! [16…Qg2 17.Re1 Bf3 18.Kc1 Nc6 19.Qe3. White stands better.] 17.Kc1 Qe2 [17…Nc4 18.Bh8! Qe2 19.Rd1, and White stands better.] 18.Rd1 Bb4 19.Qe3 with the unclear position. 

B2) 13…Nf6 14.Qd8!  

x) 14…Nc6 15.Qxd7+! Ne7 [15...Be7 16.0-0! with the advantage] 16.Qd4 Nc6 17.Qxf6+ Qxf6 18.Bxf6+ Kxf6 19.c3 Ne5 20.f3! with the advantage. 

y) 14…Bxb4 15.Qxd7+! =. 

 

Part 2: The Woman Player’s Luck opening (C20) 

 

The above new analysis of the Nightingale gambit allows to get new appraisals of some systems of the Woman Player’s Luck opening (the Bednikova opening, C20): 

 

I) 1.e4 e5 2.b3 Nf6 3.Nc3 Bb4 4.a3!? AN Ba5 [4…Bc3 5.dc, and White has a good position, because after 5…Ne4?! White gets an advantage: 6.Qd5 (or 6.Qg4) 6…Nc3 7.Qe5 Qe7 8.Qe7 Ke7 9.Bb2 with 10. Bg7.] 5.b4!? Bb6 6.Na4 [We can see the Chase variation reflected here. If you play as White and know that your opponent likes the Nightingale gambit very much (when he plays as White) and if you want to play against it, then the Woman Player’s Luck opening is an excellent way for you to start this game.] Thus, after 6…Bxf2+!? we can see the Nightingale gambit reflected.  

 

II) 1.e4 e5 2.b3 Nf6 3.Nc3 Bc5 4.Na4!? Bxf2+!? 5.Kxf2 Nxe4+ 6.Ke2 Nf2!? AN [Our first novelty was 4.Na4 here, but it was published (with our whole tree of subvariations) in our article ‘The Only Opening Named after a Woman: the New’ on the page “Bruno’s Chess Articles”, so it’s a part of the modern chess opening theory now.] 7.Kxf2 Qh4+ 8.g3! [8.Ke2?! Qe4 9.Kf2 Qd4 10.Ke1 Qa1, and Black has an advantage] 8…Qd4+ 9.Kg2! Qxa1 10.Nc3!?  

1. 10…c6?! 11.Nf3. Here the way 11…d6? 12.Ne4 Bg4 is bad, because after 13.Nxd6+! Ke7 14.Ne4! (with the idea 14…f5?? 15.Ba3 and 16.Qa1) White wins. Black can play 11…d5 or 11…0-0 instead with White’s response 12.Nxe5 in both cases, but White has a large advantage in both cases, because White can play 13.Ba3!? Qxd1 14.Nxd1. Also Black can play 11…e4 12.Nxe4 0-0!, but after 13.Nc3!? White plays 14.Ba3!? and has a large advantage too. 

2. 10…b6 11.Be2 Bb7+ [or 11…Na6!? with the unclear position] 12.Bf3 Nc6 with the unclear position. 

3. 10…0-0 [It’s a sacrifice of the c-pawn.] 11.Nd5 Nc6 12.Nxc7 Rb8 13.a3 Qd4!? with the unclear position. 

 

Part 3: The Popov variation (C60) 

 

Easily each Internet user can find initial stages of two games with the Spanish opening (Spanish game, C60) by the Bulgarian ICCF GM Georgi Popov where he has played successfully as Black: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a5!? with the move 4…Na7 after 4.d3?! (against Mr. Nikolov, 1990) and after 4.0-0! (against Mr. Kuczynski, 1991). Thus, several experts call 3…a5 as “the Popov variation” (or as “the Bulgarian variation /defence”), other experts use this name for 3…a5 4.d3 Na7 and 3…a5 4.0-0 Na7 only. The move 3…a5 isn’t a very good defence, but the modern chess opening theory doesn’t give real proofs for this conclusion. Our new following analysis permits to get these proofs for these two lines. 

 

I) 1.e4 e5 2.Nf3 Nc6 3.Bb5 a5!? 4.d3?! Na7 5.Bc4! [It’s our new appraisal of this move. The way 5.Ba4 b5 6.Bb3 is good too, and it’s also our new appraisal.] 5…b5 6.Bb3 [6.Bf7! AN is good too.] 6…a4 7.Bxf7+! AN Kxf7 8.Nxe5+ Ke7 9.Nf7!? [Other moves will not be considered here, although there are some strong attacking ones among them.] 9…Kxf7 10.Qh5+ g6 [10…Ke7?! 11.Qe5 Kf7 12.Qd5 Ke8 13.Qa8, and White has an advantage] 11.Qd5+ Kg7 12.Qxa8 Nc6  

A) 13.c3 with a complicated fight where White gets an advantage. 

B) 13.Be3 with a complicated fight where White gets an advantage. 

C) 13.Na3 Bxa3 [13…Nb4 14.Be3 with the advantage; 13…Nd4 14.Qd5 with the advantage] 14.bxa3 Nf6! 15.Bb2, and White gets an advantage. 

 

II) 1.e4 e5 2.Nf3 Nc6 3.Bb5 a5!? 4.0-0! Na7 5.Bc4! AN [The little-known way 5.Ba4 b5 6.Bb3 a4 7.Bf7! is good too.] 5…b5 6.Bb3 [6.Bf7! AN is good too.] 6…a4 7.Bxf7+! Kxf7 8.Nxe5+ Ke7 9.Nf7! [Other moves will not be considered here, although there are some strong attacking ones among them.] 9…Kxf7 10.Qh5+ g6 AN [10…Ke7?! 11.Qe5 Kf7 12.Qd5 Ke8 13.Qa8, and White has an advantage] 11.Qd5+ Kg7 12.Qxa8 Nc6 13.c3! with a complicated fight where White gets an advantage. 

 

Moreover, it should be added that 4.Nc3 [GM Lubomir Kavalek recommended it in his newspaper chess column in 1998, May 4, as the best move and as the refutation of the Popov variation: “Of course, after 3…a5 white plays 4.Nc3 and the Bulgarian defense is shelved”.] should be met by 4…Nd4! AN, and the position is unclear [Black has or the equal position, or even the advantage].
