A Whole Lot In There

Chessfriend Philidor 1792 has delivered another large collection of exciting games: some Jerome Gambits and some Jerome Gambit-related openings.

For a three-minute blitz game, the following match has a whole lot in it. White improves on earlier efforts (a dozen or so moves into the game) and carries the fight from the opening through the middle game to the endgame. When his opponent slips, Philidor 1792 executes a piquant checkmate.

Good to the End

The Jerome Gambit is a strange opening. White gets what he wants by giving Black a winning game. Black often fights to reach an even game, by giving up his advantage. The winner is the one who makes sense of this, and wins in the end.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4 Nxd4

I have to say that I am not very familiar with this "modern" (no 5.Nxe5) Jerome Gambit variation, even though I discovered that there are over 530 games in The Database with this position, including games by Jerome Gambit regulars like Darrenshome, DragonTail, drumme, ItsAllBullCheck, and yorgos.

Of course, Bill Wall is willing to experiment just about any game.

6.Nxe5+ Kf8 7.Be3 Ne6 8.Qh5 Qe7

Bill notes 8...Qf6 9.Nxd7+ Bxd7 10.Bxc5+ Ne7 11.Nc3 Nxc5 12.Qxc5 Qb6; not 8...g6? 9.Nxg6+.

9.Nc3 c6

White has equalized. It is important to remember the old adage: In the Jerome Gambit, when White has equalized, he has the advantage.

10.Ng6+ hxg6 11.Qxh8 Bxe3 12.fxe3 Ng5 

Bill prefers 12...Nd8.

13.Rf1+ Nf7 14.h4 Qe5 

As is frequently the case, 14...d5! is the move.

15.0-0-0 Qh5 16.Rxf7+ Kxf7

Not 16...Ke8?? 17.Qxg8#

17.Rf1+ Nf6 18.Qxh5 gxh5 19.e5 d5 20.exf6 gxf6

Black - or is it White? - has made it through the opening and the middle game and now has a roughly even endgame.

21.e4 d4

Or 21...Be6 22.exd5 cxd5 23.Nb5

22.Ne2 c5 23.e5 f5 24.Nf4 Be6 25.Nxh5 Rh8 26.g4

26...Kg6

Better 26...Rh6 or 26...b5. 

27.Nf4+ Kf7 28.gxf5 Bxf5 29.h5 Re8

This is a mistake that turns a position with a lot of drawing potential into a loss. The "Jerome pawns" can no longer be contained.

Still A Bad Idea

One benefit of Jerome-izing the Blackburne Shilling Gambit is that the game becomes transformed, and ideas that were playable in the original opening become sketchy in the "modified" version. That was true when we looked at the opening variation in the following game, four years ago, and it remains true today.

A thematic move for the plain Blackburne Shilling Gambit, as covered in "Reeling Sequel", but not as strong here as taking the Knight.

7.cxd4 Qxg2 

Still leading to mate. It is worth knowing these things.

8.Qb3+ Kf6

Black holds out a move longer with 8...d5, i.e. 9.Qxd5+ Kf6 10.Qf7+ Kg5 11.h4+ Kh6 12.d3+ g5 13.hxg5#

Snake Eyes

Shades of "Jerome's Double Gamble", the following game is the only one in the current Italian Game Thematic Tournament at Chess.com where I was able to play a Jerome Gambit - and it has the same feel as Bill Wall's last game: the wrong opponent at the wrong time...

Updating the Blackburne Defense (Part 2)

9...Nf6 10.Qd8 Qxe4 

Black's move allows White's Queen to escape and counter-attack. There are a number of alternative moves for Black, two of which bear attention.

Not 10...a6?, as in piratebopper - MiloBot, FICS, 2010, (1-0, 24).

Nor 10...a5? as in perrypawnpusher - MiloBot, blitz, FICS, 2010, (1-0, 24).

Played, if in a stumbling manner, is 10...Bd7?. The core game continued 11.Qxc7 (instead, 11.Qxa8? Nxe4? [Black should finish Blackburne-style: 11...Ng4 12.h3 Bxf2+ 13.Kh1 Qg3 14.Rxf2+ Nxf2+ 15.Kg1 Nxh3+ 16.Kh1 Nf4 17.Qf8+ Kxf8 18.d3 Qxg2#] 12.d4 Bxd4 13.Be3 Bxb2 14.Qxb7 Bxa1 15.Qxc7 Nf6 16.Qxd6 Kg7 17.Qc5 Ne4 18.Bd4+ Bxd4 19.Qxd4+ Kh6 20.f3 Black resigned, UNPREDICTABLE - choron, FICS, 2009) 11...Bb6? (instead, 11...Rc8 12.Qxb7 Ke7 is "gloriously obscure" according to Dr. Andrew Walker, University of Nottingham, personal communication, 2001. Probably 13.Qb3 with the idea of Qg3 is White's answer - not 13.Nc3? Ng4 when Black mates)  12.g3?! (12.Qxd6) 12...Qh3 13.Qxd6? Bc6 14.g4 Qxg4+ White resigned, Harris,S - Quayle,E, Los Angeles, CA, 1944.

Certainly solid, and Rybka's recommendation, is 10...Bb6. White should spring his Queen with 11.e5 dxe5 12.Qd3. The earliest reference that I have seen to this line is from The Art of the Checkmate by Renaud and Kahn (1953), which says White has the advantage. This proved true in Wall,B - Foo,N, Palm Bay, FL, 2010 (1-0, 33).

The most exciting move in the position is Chandler's 10...Bh3!?, when White has to temporarily forego the Rook at a8 and focus on checking Black: 11.Qxc7+ (11.g3? Qxe4 12.Qxc7+ Kf8 White resigned, Siggus -toe, FICS, 2007; 11.Qxa8? Qg4 12.Qe8+ Nxe8 13.g3 Qf3 14.Re1 Qg2#) 11...Kf8! (11...Kg8 lost in Chandler,G - Dimitrov, T/5 minute special game 2004; in Hiarcs 8 - RevvedUp, blitz 2 12, 2006 [1-0, 17]; and AsceticKingK9 - blackburne, ChessWorld JG6, 2011 [1-0, 22] ) and analysis by Geoff Chandler and, later, Dennis Monokroussos (see the two posts on his blog) show that the outcome is a draw, as it is too dangerous for either player to look for more.

11.Qxc7+

This is an improvement over 11.Nc3 Qe7 (11...Qxc2 12.Qxc7+ Nd7 13.Nd5 Qe4 14.Nc3 Qe5 15.d3 Qd4 16.Re1 Qxf2+ White resigned, ionman - GriffyJr, FICS, 2005 (0-1,16); Interested readers should check out "Ionman vs The Bots" ) 12.Qxe7+ Kxe7 as in RevvedUp - Shredder 8, blitz 2 12, 2006 (0-1, 25).

11...Kg8

radicalmove played over a dozen games against LuigiBot on FICS in 2012, testing the somewhat weaker 11...Bd7 (see "Poor, Poor Computer" for a couple of examples). The games are in The Database.

Likewise, ionman took on the computer GriffyJr a couple of times at FICS in 2005, over the somewhat weaker 11...Qe7 (the games are also in The Database). White triumphed in Shredder 8 - RevvedUp, blitz 2 12, 2006 (1-0, 28).

12.Nc3

Maybe a little better was 12.Qd8+ Kf7 13.d3 Qe5 14.Bh6 Qe8 15.Qxe8+ Nxe8.

12...Qxc2

The pawn is poison.

13.Qd8+ 

After the game Houdini preferred 13.d4!? Bb6 (13...Bxd4 14.Bh6 Bd7 15.Qc4+ d5 16.Qxd4) 14.Qe7 when White steals the Knight in broad daylight.

13...Kg7 14.Qe7+ Kh6 15.Qxf6 Black resigned

Updating the Blackburne Defense (Part 1)

Chess players who know about the Jerome Gambit are most familiar with the game Amateur - Blackburne, London, 1885. Many believe that the Blackburne Defense, when played properly, leads to an advantage for the second player.

Players a bit more familiar with the Jerome Gambit and past published analysis might well believe that White has the advantage.

Readers familiar with this blog would know that modern analysis has termed the Blackburne Defense as difficult, but actually a draw.

I thought of all of this as I played my most recent game, and decided that the Blackburne Defense needed another update.

Of course, you can start first with earlier efforts: "Update: Old Dog Can Still Bite", "A Closer Look (Part V)", "Update: Blackburne Defense" and "Junk Openings".

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6

Here is the famous Blackburne defense, from Amateur - Blackburne, London, 1885. The Brooklyn Chess Chronicle (edited by J.B. and E.M. Munoz) Vol. III, August 15, 1885, p. 169, noted the game was

"played some months ago in London between Mr. Blackburne and an Amateur..."

8.Qxh8 Qh4

Here Amateur played 9.0-0. The editors of the Brooklyn Chess Chronicle suggested

He should have attempted to free his pieces by P to Q4 before castling. 

Although my opponent lfcanales played 9.0-0 as well, I would like first to look at the under-investigated 9.d4. After all, if 9.0-0 leads to a draw, as Chandler and Dimitrov have argued, then 9.d4 might be the better chance for White to fight for an advantage.

Here is some of what I have found.

After 9.d4, thematic and best for Black is 9...Nf6, although other moves have been played.

For example, Black has the alternative 9...Qxe4+ 10.Be3 Qxg2 -best - there have been several games with lesser 10th moves:

Scenario: Don't be misled by White's extra Rook. It's a meaningless ornament. White is in serious trouble. His King is exposed and his cornered Queen is in danger of being trapped. The cruncher is 12...Bh3 which wins White's Queen by discovery from the a8-Rook.

Actually, the correct response to 11...Qxg2? is 12.Nc3!? which later prevents Black's Knight from moving to e4 and giving mate. After  12...Qxh1+ 13.Kd2 Qxa1? White turns the tables with 14.Bd4! (13...Qxh2 would keep Black's Queen in play) when Black's extra Rook would mean little in the face of White's strong counterattack.

Also, 10.e5 does not appear as strong as 10.Nd2 - and seems more dangerous for White - after 10...dxe5 11.Nd2 (11.dxc5? Qe4+; 11.dxe5?? Qxf2+ 12.Kd1 Bg4 mate) Bxd4 12.0-0 Be6!? 13.Qxa8 Bd5 14.Qc8 Ng4 15.Qxc7+ Ke6 16.Nf3 Bxf3 17.Bf4 Bxf2+ 18.Kh1 exf4 19.Qxf4 g5 20.Qb8 Be2 21.c4 Bxf1 22.Rxf1 Nf6 23.Qc8+ Ke5 24.Qxb7 Ne4 White has an edge, analysis by Houdini.
