An Email Discussion


Earlier this month I received two emails from chessfriend Yury Bukayev. The first, with the subject "Your post of July 18 has a large error‏" and contained the following
Your post of July 18 has a large error. Thus, you have published your appraisal of the position: 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6? 4.b4?! Bxb4? 5.c3 Ba5 as winning for Black. It isn't true! Look, please, Paragraph 2, part III of my article! Yury 
http://chessproblem.my-free-games.com/chess/games/ChessArticle.php?art=C51 
The second email, with the subject "Else about your error in the post of July 18‏" continued
The position 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6? 4.b4?! Bxb4? (4...d6 =) 5.c3! leads to Evans-Bukayev gambit in all cases: http://chessproblem.my-free-games.com/chess/games/ChessArticle.php?art=C51 . It isn't important, is White's pawn on d2 or on d3. Dear Rick, I suggest you to write a new post in August about it. I think, my 2 Evans-Bukayev gambits have done the Evans idea immortal for strong theory.
My response was pretty straight-forward
I will take another look at my July 18th post, at your two emails, and your article, and post about it all on my blog.
At this point I can say that I wrote that after 1.e4 e5 2.Bc4 Nc6 3.Nf3 h6 4.b4 Bxb4, Houdini 3, at 22 ply, gives Black an advantage of about 1/3 of a pawn. That much is factual - and neither Houdini 3 nor I consider "1/3 of a pawn" as "winning" for Black.
The game wardcleophus - Kiera, blitz, FICS, 2013, which I gave in the notes in the blog post, continued 5.c3 Ba5 and Black did win - but only after White immediately blundered with the Jerome-ish 6.Bxf7+? If, instead, White plays 6.0-0 the situation would be completely different from the game. Likewise, if Black plays 6...Nf6 (instead of 6...d6, similar to your article) the second player does not look lost, either.
Readers are encouraged to review the offending post, "Creative Exercise" and decide for themselves.

Essence of Evans / Jerome / Halloween

In the following blitz game Philidor1792 shows his typical creativity, aggression and persistence in whipping up an interesting attack. Resistance is strong, however, and this time White does not win the day.

Philidor1792 - Guest292640
5 0, PlayChessbase.com, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6

The Two Knights Defense, avoiding the Evans Gambit and lesser gambits like the Jerome.

4.b4 

Philidor1792 wishes to have his gambit anyway!

This move makes me wonder why we haven't seen this gambit against the Hungarian Defense, i.e. 3...Be7 4.b4!? as if the pawn is captured, the game becomes and Evans Gambit after all.

In the text, White enters an Evans Gambit a move down, as Black's Bishop comes to b4 in one move, not the usual two. Philidor1792 doesn't fret over such trivialities.

4...Bxb4 5.c3 Be7 6.Bxf7+ 



Adding a dash of Jerome...

6...Kxf7 7.Nxe5+ 

...and a splash of the Halloween Gambit, to top it off.

7...Nxe5 8.d4 Nc6 

9.e5 Ng8 10.f4 d5 11.f5 Bh4+ 12.g3 Bg5 13.Qh5+ g6 



14.Qxg5

White is not afraid to enter an endgame with the pawns against Black's extra piece, but in this instance he might have had better chances (compared to the game) after 14.fxg6+!? Kg7 15.Bxg5 Qe8 16.0–0 hxg6 17.Bf6+ Nxf6 18.exf6+ Kf7 19.Qxd5+, although Black would still be objectively ahead.

14...Qxg5 15.Bxg5 Bxf5 16.0-0 Ke6 17.Nd2 h6 18.Be3 Nge7


19.Nb3 b6 20.a4

Looking for open lines and play on the Queenside.

20...Raf8 21.a5 Bc2 22.Nd2 Nf5 23.Bf2 Bd3 24.Rfc1 Rf7 25.axb6 axb6 26.g4 Nfe7 




27.Be3 h5 

Looking for open lines and play on the Kingside.

Alas, no victory today for the Evans / Jerome / Halloween pawns.

Evans Gambit À La Jerome


From the latest collection of Jerome Gambit and Jerome-inspired games by Philidor1792...

Philidor1792 - Stranger

Casual Game, Chess-Samara.ru, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4




The Evans Gambit.


4...Bb6 5.b5 Na5 6.Bxf7+




With a Jerome Gambit twist.


6...Kxf7 7.Nxe5+ Kf8 8.Bb2




The alternative 8.d3 was seen in Philidor 1792 - guest2019, www.bereg.ru, 2013 (1-0, 33); while 8.Qf3+ appeared in Castled - perrypawnpusher, blitz, FICS, 2008 (0-1, 42).


8...Qf6


A tactical oversight. 8...Qh4 was seen in Philidor 1792 - guest344, www.bereg.ru, 2013 (1-0, 22).


9.Nxd7+ Bxd7 10.Bxf6 Nxf6




Black has three pieces for the Queen - but White has three extra pawns.


11.d3 Bxb5 12.0-0 Re8 13.Nc3 Bc6 14.Ne2 Ke7 15.Ng3 Kd8 16.Kh1 h6 17.f4 Kc8 


Black has castled-by-hand - to the Queenside. An interesting battle lies ahead.


18.Nh5 Nxh5 19.Qxh5 Bd7 20.c4 Bd4


Possibly not well thought out, as it surrenders two pieces for a Rook.


21.Qxa5 Bxa1 22.Rxa1 a6 




It is time for the "Jerome pawns" to assert themselves.


23.e5 Bc6 24.d4 g5 25.d5 Bd7 26.g3 Bf5 27.Kg1 gxf4 28.gxf4 Rhg8+ 29.Kf2 Bh3 30.Rg1 Rxg1 31.Kxg1 Rg8+ 32.Kf2 Rg2+ 33.Kf3 Rg8 


Not 33...Rxh2, because of 34.Kg3, winning a piece.


Now Black's game collapses.

Not Quite the Evans-Jerome Gambit


Even when Philidor 1792 does not play a "true" Jerome Gambit, he finds ways to add its flavor to his blitz play. In the following game he experiments, too, with the Evans Gambit. The result, as in many 3-minute games: aggression, persistence, creativity and win.

3 0 blitz, www.bereg.ru 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.a3



A bit of a twist - usual for the Evans Gambit is 5.c3. Philidor 1792, as we know, likes to experiment.


5...Ba5


Or 5...Be7, which took a non-Jerome path: 6.Ba2 Nf6 7.Nxe5 Nxe5 8.d4 Nc6 9.d5 Ne5 10.f4 Ng6 11.e5 Ng8 12.d6 cxd6 13.Qd5 Nh6 14.exd6 Bf6 15.f5 0-0 16.fxg6 Bxa1 17.Bxh6 Qh4+ 18.Kd1 Qxh6 19.gxf7+ Kh8 20.Re1 Qg6 21.Nd2 Bc3 22.Re8 Rxe8 23.Qg5 Qe6 24.Bxe6 Black resigned, Philidor 1792 - guest55, 3 0 blitz, www.bereg.ru, 03.02.2014


6.Bxf7+ 


Giving the Evans-ish opening a Jerome-ish spin.

Bringing the Heat


Sometimes the Jerome Gambit just doesn't seem aggressive enough - yes, I know, that can be hard to believe. In those cases, it might be appropriate to reach back further in time, and put together a hybrid gambit - something that Philidor 1792 is an expert in.

The Evans Jerome Gambit Declined

Philidor 1792's gambit play is out-running my naming nomenclature! In the game below, Black manages to decline the Evans Gambit, but accepts the Evans Jerome Gambit. I think...


Philidor 1792 - guest344
3 0 blitz, www.bereg.ru, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 




The Evans Gambit. This time, Black declines the pawn.


4...Bb6 5.b5 Na5 6.Bxf7+ 




The Evans (Declined) Jerome Gambit?!


6...Kxf7 7.Nxe5+ Kf8 8.Bb2 


Varying from 8.d3 as in Philidor 1792 - guest2019, 3 0 blitz, www.bereg.ru, 2013 (1-0, 33) and 8.Qf3+ as in Philidor 1792 - guest343, 3 0 blitz, www.bereg.ru, 2013 (1-0, 41). 


8...Qh4 9.Qe2 Nf6 10.d3 d6 11.Nf3 Qh5 12.Nbd2 Kf7 13.0-0 Re8 




14.Rfe1 d5 15.e5 c6 16.a4 Bg4 17.h3 Bxf3 18.Nxf3 Re6



This gives White a target, and his pieces quickly swing into action.


19.Qd2 Nd7 20.Ng5+ Ke7 21.Nxe6 Kxe6 22.Bc3 Black resigned

Is There No Escape?


The following game is a beautiful example of the coordination of pieces and pawns that occurs in a deadly attack. Black's game slowly slips away, until he has nothing left but to face checkmate.


Philidor 1792 - guest1132
3 0 blitz, www.bereg.ru, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 




4...Bxb4 5.c3 Bc5 6.Bxf7+ 




6...Kxf7 7.Nxe5+ Nxe5 8.Qh5+ Ng6 9.Qd5+ Ke8



Instead, Charlick - Holloway, Australia, 1877 (1-0, 76),the earliest example of the Evans Jerome Gambit in The Database, continued 9...Kf8.


10.Qxc5 Nf6 11.0-0 Kf7 12.f4 Re8 13.f5 Ne5 14.d4 d6



15.Qb5 Nc6 16.Nd2 Kf8 17.Qd3 Kg8 18.Bb2 Qe7




Black has castled-by-hand, while White has readied his "Jerome pawns".


19.c4 Bd7 20.Bc3 Qf7 21.Rae1 Rad8 22.e5 dxe5 23.dxe5 Bc8



24.Qg3 Nh5 25.Qh4 g6 26.e6 Qe7 27.Qg4 Qc5+ 28.Kh1



28...Ne7 


Black might have done better by sacrificing the exchange to get rid of White's dangerous Knight, with 28...Rxd2.


Now White's attack crashes through.
