Another look at the Sarratt Attack

A propos the "Sarratt Attack" which I have looked at in a few posts on this blog, I should have mentioned the three-part series of articles at chess.com by "mikrohaus2014" which gives excellent historical and analytical coverage: Parts 1, 2, and 3.

Can You "Jerome" everything?

A game I recently saw at quebecechecs.com got me thinking: can you "Jerome" everything?

Dorion,Francois - Ouellet,Paul-G
1993

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nce7 

An extravagant move that calls out for some kind of response. Of course, 4.Nxe5 comes to mind, first... 

It is not clear what Black's idea is - likely he has been away from the game for a while. Yet, I have uncovered two more games with the move (see below).

4.Bxf7+

Understandable. White would like to end the game quickly.

4.Nc3 c6 5.d3 d5 6.exd5 cxd5 7.Bb3 Nf6 8.Nxe5 Ng6 9.Nxg6 hxg6 10.Bg5 Bb4 11.h3 0-0 12.0-0 Bxc3 13.bxc3 Qa5 14.Bxf6 gxf6 15.c4 Be6 16.Qf3 Rad8 17.Qxf6 Qc5 18.Rfe1 d4 19.Re4 Rd6 20.Rh4 Qh5 21.Rxh5 gxh5 22.Qg5+ Kh7 23.Qxh5+ Kg7 24.Qe5+ Black resigned, Boyer,M - Miller,D, Blackpool, 1993. 

4.0-0 Nh6 5.Nc3 Nc6 6.d3 d6 7.Bg5 f6 8.Be3 Bg4 9.h3 Bxf3 10.Qxf3 g5 11.Rad1 g4 12.hxg4 Nf7 13.g5 fxg5 14.Qh5 (14.Qxf7#) 14...Ne7 15.Nd5 (15.Bxf7+ Kd7 16.Qg4+ Nf5 (16...Kc6 17.Bd5+ Nxd5 18.exd5#) 17.Qxf5+ Kc6 18.Bd5#; 15...Ng6 16.Nb4 Nf4 17.Qxf7 checkmate, Oberhofer,C - Fürst,Lm Österreichische Meisterschaften,  2011. 

4...Kxf7 5.Nxe5+ 

Very Jerome Gambit-ish. Black would do well to withdraw his King with 5...Ke8 now, but his monarch is never really going to feel comfortable.

5...Ke6 6.Qg4+ 

In for a penny, in for a pound.

White sacrifices another piece to make the position even more terrifying for the enemy King. In the cold light of day, however, and psychology aside, 6.d4 was "objectively" more sound.

6...Kxe5 7.d4+ Kf6 8.Qf4+ Kg6 9.e5 d6 10.Nc3 

10...Nh6 11.h4 Nhf5 12.g4 Kf7 13.gxf5 Bxf5 14.Ne4 dxe5 15.Ng5+ 

Black had defended remarkably well. He only has to think of "castles-by-hand" for his next move, and he should weather the storm.

15...Kg6 

Tempting fate. The move-to-make was ...Kg8.

16.dxe5

Surprisingly, White overlooks 16.h5+ Kf6 (16...Kh6 17.Nf7#) 17.Qxe5 checkmate.

16...Nd5

Black could fight on a bit longer with 16...h5, but there would be no joy in it.

17.h5+ Kh6 18.Nf7 checkmate

A Tough Loss

I have to admit that I felt a little bad after discovering the following game. Played in the Under 1400 section of the 2014 Colorado Open, it featured the adventurous play of someone with only a little over a dozen rated gamed under his belt.

That White was willing to trust his play against the Blackburne Shilling Gambit (from the eventual winner of the section) - there certainly are other ways to attack the BSG - to the "Jerome treatment" in an over-the-board event was a reflection of his pluck. That he got lost in a sideline... a reflection of his bad luck.

So, here is a restorative lesson.

Zirin, Jacob - Akhavan, Evan
Colorado Open, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+

The Blackburne Shilling Jerome Gambit.

White can also play 4.Nc3, 4.0-0, 4.d3 or (best) 4.Nxd4 exd4 5.c3 without risk. (Just stay away from 4.Nxe5 on principle.)

4...Kxf7 5.Nxe5+ Ke6 6.Qh5 

The Database has 1,329 games with the Blackburne Shilling Jerome Gambit after 5...Ke6, with White scoring 52%.

The Database has 117 games with White's 6.Qh5, scoring 52%.

Found in 407 games in The Database is 6.c3, which, while complicated, scored 59%.

My recommended line for White here starts with that last move: 6.c3 Kxe5 7.cxd4+ Ke6 and the game is balanced. It is too dangerous for Black to capture either (any) of the center pawns; that gives the first player too many chances to "capture" the enemy King.

Since this is blog post number 2,064, you would have to look through a lot of information to bring yourself up-to-date on this variation. Let me help.

To learn about the line, it is useful to progress through the following blog posts, in order, from oldest to more recent: "Blackburne Shilling Jerome Gambit 2", "Why, I oughta...", "Clearly Unclear", "Untangling Lines of Play", " 'Even' does not mean 'safe' ", "Whose Territory Are We Fighting On?", "Starting Over", "Not-So-Instant Victory", "More Updating", "A High Level of Danger", "Blackburne Shilling Gambit: Don't Feed the Greed", and "Caught Out".

(Of course, if you are in a hurry, start from the last and read as many as you can, progressing backwards and checking out the references to earlier posts.)

If you are going to play 6.Qh5, here are a few guidelines from past posts: "Read This Blog", "Scared to Death" ,"Greed Is Not Good" and "Is Still Not".

You're welcome. 

6...Qf6 

Even stronger was 6...Nf6. 

7.Nf7 

White goes after Black's Rook, before Black goes after White's Rook. In theory, attacking first may be a good idea, but here the move (a TN) loses a pawn. Better, according to Stockfish, is 7.Ng4 Qg6 (not 7... Nxc2+ 8.Kd1 Qg6 9.Qxg6+ hxg6 10.Kxc2 when White has an edge) 8.Qd5+ Ke7 9.Qxd4 Qxg4 10.O-O and Black would have his one piece vs two pawns advantage.

7...Nxc2+ 8.Kd1 Qxf7 9.Qd5+ Ke7 10.Kxc2 Qxd5 11.exd5

With Queens off of the board, Black's King is relatively safe. White will have a difficult time scaring up an attack against a position with few weaknesses.

11...Kd8 12.d4 Nf6 13.Nc3 d6 14.f3 Bf5+ 15.Kb3 Kd7 16.Bf4 Re8

17.h4 h5 18.Rac1 a6 19.a4 g6 20.Kc4 Bg7 21.Rhg1 Re7 22.Bg5 c6 23.g4 hxg4 24.fxg4 cxd5+ 25.Nxd5 Be6 26.Bxf6 Bxf6 27.g5 Bg7 

Here White resigned, as the upcoming 28...Rc8+ will chase White's King away from protecting the Knight.

More Errors in Thinking 3.2

[continued from the previous post]

perrypawnpusher - Heler, 

Chess.com, Giuoco Piano tournament, 2015

17.Bxf6

As Bill Wall had suggested, as an improvement over the previously played 17.Rae1.

17...gxf6 18.Nd5

As in my play against Hywel2. I wasn't sure if my change in move order was going to bring about anything more than a transposition; for example, if Black were now to play 18...Qg7 and I were to follow up with 19.Rae1, then 19...b6 would put us back in the earlier game.

18...Qf7

Black varies, as well, with the placement of his Queen.

19.Rae1 b6 20.Nf4 a5

The difference from the previous game is that White's Knight is now at f4, not d5, and his Rook is at f1, not f3. This allows Black's threat of ...Ba6 skewering White's Queen and winning the exchange.

I thought pressure along the c-file was the answer, allowing White's Knight to reach a beautiful outpost, but putting his Queen in the line of fire. Her Majesty eventually has to move again.

21.Qc3 Bb7 22.Ne6 Rac8 23.Rf3 Nd8 24.d5 c6 25.Qd2 cxd5 26.exd5

White has two pawns for a  piece, and a nice-looking Knight, but Black's army looks pretty active.

26...Qh5

A shock. I was planning on playing on the Kingside. What was my opponent doing??

I figured out a line that might give White the initiative, but I was still worried about Black's Queenside forces.

27.Nf4 Rxe1+ 28.Qxe1 Qf7 29.Re3 Nc6

White pins his hopes on the e-file and Black's weakened back rank, (as well as the possibility of a tricky tactic from the Hywel2 game). My opponent decided it was time to return the sacrificed piece.

30.dxc6 Bxc6 31.Re7

White is a pawn up, and Black decides to level the material.

31...Qxa2 32.Qc3

Suddenly, Black is in grave danger.

For example, if now 32...Rf8, to protect the f-pawn, White has 33.Ng6+ (a tactic right out of the earlier perrypawnpusher - Hywel2 game, which made it easy to see) Kg8 (if 33...hxg6 then 34.Qh3+ leads to mate) 34.Nxf8, and Black can only avoid checkmate by giving up his Queen, e.g. 34...Qa1+ 35.Re1 Qxe1 (or 35...Qa2 36.Ne6 Qxe6 37.fxe6) 36.Qxe1 Kxf8 when the imbalance in material is too great.

32...Kg8 33.Qg3+ Black resigned

More Errors in Thinking 3.1

The title of this post comes from a couple of previous ones - "More Errors in Thinking" and "More Errors in Thinking 2.0" - and can be explained by the truism I related earlier

One of my interests in exploring the Jerome Gambit comes from observing - and occasionally provoking - "errors in thinking". Essentially, the only way White can win is if Black errs - sometimes in the most fascinating of ways.

In the first of the two posts I presented the Jerome Gambit game perrypawnpusher - Hywel2, Chess.com Italian Game tournament, 2015, with the gushing note

For a while it looked like it was going to be one of my best Jeromes ever, thanks to some fun tactics - but I fell victim to my own "error in thinking", and it was all for naught...

In the second of the two above posts, I presented the game again, adding notes and suggestions by Bill Wall, longtime Jerome Gambit Gemeinde member.

It all was in the service of some mental hand-wringing, the likes of which I have done before, for example, about a year ago in "Jerome pawns - Clowning Around"

After my discouraging loss with the Jerome Gambit in my previous Chess.com Italian Game tournament (perrypawnpusher - Buddy_Thompson), I knew that I had to cook up something new, or risk facing a future opponent who just "looked the refutation up" (and not even on this blog, mind you, but in my recent games on Chess.com).

Such worry bore fruit, however, in terms of a win in my return game with djdave28, as the post showed.

So - recently I played a couple of Jerome Gambits, one too-quickly leading "Toward Disaster" with the other "following, step-by-step, a recent loss of mine from a Chess.com Italian Game tournament."

As you might guess, that "recent loss" was the game chronicled in "More Errors in Thinking" and "More Errors in Thinking 2.0", perrypawnpusher - Hywel2, Chess.com Italian Game tournament, 2015.

So, "without further ado" as they say, let us take a look at my latest Jerome Gambit win, (with earlier notes cribbed from earlier posts).

perrypawnpusher - Heler, 
Chess.com, Giuoco Piano tournament, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.O-O Kf7 11.f4 Re8 12.f5 Ne5 13.d4 

I have also tried 13.Nc3 in perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23); perrypawnpusher - darqknight, blitz, FICS, 2011 (0-1, 63); perrypawnpusher - CorH, blitz, FICS, 2011 (1-0, 24); and perrypawnpusher - yasserr, blitz, FICS, 2011 (1-0, 32).

13...Nc6

Oddly, this natural move was a TN according to The Database until perrypawnpusher- Hywel2, Chess.com, Italian Game tournament, 2015

Instead, 13...Neg4 was seen in Vazquez,A - Carrington,W, Mexico, 2nd match 1876 (1-0, 34);Wall,B - Vijay,V, Chess.com, 2010 (1-0, 22) and perrypawnpusher - whitepandora, blitz, FICS, 2011 (1-0. 64).

14.Nc3 Kg8 15.Qd3 Kh8 16.Bg5 Qd7

So far, all replay of the earlier game; but things were about to change.

[to be continued]

  

Another Zeromov Gambit

As a follow-up to the last post, let me point out that the presenter has many interesting videos online - including the game Nelson vs Sugar, which is another interesting Jerome Gambit. Since I have not shared that game on this blog, let me do so, now.

Nelson, Lamoni - Sugar, Zoltan
Jamaica, Queens, USA, 2006

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4....Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6 

In an earlier post, "Jerome Gambit Doctor", the direct 6...Be7 was examined, as in HauntedKnight - Josue, FICS, 2012 (0-1, 29).

7.dxe5 Be7

Black wants no part of 7...Bxe5 8.Qd5+. See the recent "Borrowed As Good As Own".

8.O-O d6 9.f4

The computers prefer 9.Qf3+, as seen in Idealist - throwback, FICS, 2000: 9... Nf6 10.exf6 Bxf6 11.Nc3 Be6 12.Rd1 Rf8 13.e5 Kg8 14.exf6 Rxf6 15.Qg3 Qf8 16.Ne4 Rg6 17.Qc3 Qf5 18.Ng3 Qf7 19.Be3 Rf8 20.Rf1 c6 21.Rad1 d5 22.Qb4 b6 23.Qd6 Bg4 24.Rd2 Rxd6 25.Ne4 Rg6 26.Ng5 Qf5 27.h4 h6 28.c4 hxg5 29.Bxg5 Rxg5 30.hxg5 Qxg5 31.Rd3 Rf6 32.Rg3 Rh6 33.f3 Qe3+ 34.Rf2 Qe1+ 35.Rf1 Qxg3 36.fxg4 Rh2 37.Rf2 Rh1+ 38.Kxh1 Qxf2 39.Kh2 d4 40.Kh3 d3 41.g3 d2 42.Kh4 d1=Q 43.Kg5 Qdd2+ 44.Kh5 Qh6 checkmate

9... g6 10. e6+ 

"Ain't that a kick in the head?" as Dean Martin once asked.

Black can, and maybe should, take the pawn, but things will remain complicated, thanks to those annoying "Jerome pawns".

10...Kg7 11.f5 Nf6 12.Nc3 c6 13.Bg5

Instead, Stockfish suggests the wild, but it sees as balanced, 13.g4 h5!? 14.g5 Ng4 15.Qd4+ Kh7 16.f6.

13...Qb6+ 

14.Kh1 Qc7 15.fxg6

This gives Black a saving chance. Better was 15.Qf3.

15... hxg6

The computer gives 15...Bxe6, and while the rest of the recommendation is no walk in the park for Black's King, it turns out better than the text: 16.Qd4 Raf8 17.gxh7 Rxh7 18.Rad1 Qa5 19.Bf4 Qb6 20.Qxb6 axb6 21.e5 dxe5 22.Bxe5 Kg6 23.Bd6 Bf5 24.Rfe1 Bxd6 25.Rxd6 Bxc2 26.h3 Kg7 27.Ree6. 

Now White finishes up neatly.

16.Bxf6+ Bxf6 17.Rxf6 Kxf6 18.Qd4+ Kxe6 19.Qxh8 Rb8 20.Rf1 Qe7 Black resigned

Black's Bishop and Rook will stand around, helpless, while his King is chased and checkmated.

Zeromov Gambit!?

Another recent discovery on the internet is a Serbian language video examining the famous Jerome Gambit game Amateur - Blackburne, London, 1885.

Having shown the first moves of the game - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ the presenter takes an aside to look at 6...Ke6, before continuing with Blackburne's 6...g6. There, White executes a checkmate in 17 moves - ah, well, but, anyhow, back to Blackburne...

I had to chuckle. Knowingly or not, the chess player had just shown the game Ghandybh  - ishahir, Chess.com, 2009, presented on this blog in the post "Teach / Learn" about 5 1/2 years ago.

For that matter, there had been updates in "Jerome Gambit on YouTube!?" (the game Ghandybh  - ishahir, Chess.com, 2009) and "Jerome Gambit: Winning Strategy #1".

But what really shocked me about the Serbian video was the reference to the opening as the Jerome Gambit, or the Zeromov Gambit.

I had not heard that one before. Looks like I have more research ahead of me!
