Jerome Gambit: University Adventure



According to FIDE (the international chess federation)

960 students (198 women, 762 men) of 78 countries, representing 202 universities of 64 countries participated in the First FIDE World University Online Blitz Championship on Sunday, 14-18, March 2021. It was by far the biggest university event ever.

Anyone who has ever watched the 1978 college movie "Animal House" has to know that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) would show up at the World University Online Blitz Championship - and perform in its own special way...


Chaguaceda, Lasa Juan (Universidad de Valladolid, Spain) -

3 2 blitz, 1st FIDE World University Blitz Group C, Tornelo, 2021


 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

5...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qf5+ 


Oh, no... this looks like a mouse slip.

To be fair, The Database has 6 other games with this position, and White still won twice: BoomBoomTNT-YT and Bill Wall.

The error was balanced by another game that White had in the tournament: Chaguaceda, Lasa Juan - Sithole, Sibonelo, 1.e4 1-0

7...Qf6 8.f4 Qxf5 9.exf5 Ng4 


Black has two pieces for two pawns.

White fights on, but another error seals his fate.

10.Nc3 N8f6 11.d3 d6 12.h3 Ne3 13.Ne4 Nxe4 14.dxe4 Nxc2+ White resigned

Jerome Gambit: Strategy and Tactics

 


The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is a good example of the quip by Tartakower,

Tactics is knowing what to do when there is something to do. Strategy is knowing what to do when there is nothing to do.

While it is fun to have a winning smash-and-crash attack right out of the opening, sometimes the game takes a peaceful turn, and the Jerome Gambiteer has to bide his time, making small improvements until he finally gets the opportunity to bring the full point home.


Wheeler, Jerome H. - despistado

RedHotPawn, 2021


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7 

There is little difference between 7...Ke8, 7...Kf8 and 7...Ke7.

The Database has 737 games with 7...Ke8. White scores 66%.

It has 333 games with 7...Kf8. White scores 68%.

It has 19 games with 7...Ke7. White scores 68%

Stockfish 13 (35 ply), with due consideration, prefers 7...Ke8 for Black over the other two moves, by about 1/3 of a pawn.

8.Qxc5+ d6 9.Qe3 Nf6 10.d4 Re8 11.Nc3 Kf8 12.f3 c6 

Black has a piece for two pawns and has almost castled-by-hand.

White has opted to reinforce his center, and for now will refrain from wild attacks.

Steinitz believed that the side with advantage must attack, or watch his advantage waste away. This is another reason White can afford to be patient.  

13.Bd2 d5 14.O-O-O dxe4 15.fxe4 Kg8 16.Qd3 Bg4 17.Rdf1 Be6

18.Bg5 

White targets the f6 square and thinks of breaking up Black's Kingside.

18...Rf8 19.h4 Qa5 

Black does not appear to be concerned. This puts pressure on White's King, and is an ingenious way to prevent 20.h5

20.Bxf6 Rxf6 21.Rxf6 gxf6 

Now White will cut Black's Queen off from the Kingside, and give the remaining enemy Knight the boot.

22.d5 cxd5 23.exd5 Bf7 24.h5 


Sure, the computers are okay with Black's position, but Black's amygdala has to be pumping out "Danger" messages.

24...Nf4 

This is what White has been waiting for. Instead, the retreat 24...Ne7 was called for, when the attack will continue at a slower pace.

25.Qg3+ Kh8 

Giving back a piece with 25...Ng6 would not fix things, but it might slow them down.

26.Qxf4 Qb6 27.d6 Rg8 


White now shows why he weakened f6.

28.Qxf6+ Rg7 29.h6 Qe3+ 30.Kb1 Qg5 31.hxg7+ Qxg7 32.Qxg7+ Kxg7 33.d7 Black resigned

A "Jerome pawn" tiptoes toward the Queening square... Nice!

Jerome Gambit: Very Practical Play



My last two Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games have featured sacrifices of the exchange (see "Jerome Gambit: Those Jerome Pawns, Again (Part 1)" and "Jerome Gambit: Zzzzzz.... Huh? (Part 1)"), so I was pleased to receive the following game, where White sacrifices a Rook for a minor piece - twice.

What makes the exchange sacrifices attractive is that they were not grand surprises, they were just parts of some very practical play. White was just on his way to winning the game.


n0freelunch - Ninjaaa5000

3 0 blitz, lichess.org, 2021


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 

A standard position in this line that shows up 150 times in The Database.

10.O-O Be6

Black is developing by rote, and will soon have to retract this move.

11.f4 

Of course. White threatens to fork Black's Bishop and Knight.

11...Bd7 

I was amused - but enlightened - to see that this position occurred in perrypawnpusher - Mences, 2 6 blitz, FICS, 2009 (1-0, 38) with Black to move, as my opponent had taken only 1 move to place his Bishop on d7.  

12.e5 

A bit stronger was 12.f5, but White was ready to get his attack going, starting with opening lines.

12...Nd5 13.Qe2 dxe5 14.fxe5+ Kg8

15.e6 Bc6 16.Qf2 Qf8 17.Qf7+ Qxf7 18.exf7+ Kf8 


White's advanced passed pawn gives Black something to constantly think about.

19.b4 Nxb4 

It is tempting to suggest that Black had pawns on his mind. This grab is dangerous. Simply returning the Knight to f6 was better.

20.Ba3 Bb5 

Following the old rule: If your opponent attacks one of your pieces, you don't have to defend it, you can simply attack a more valuable piece of his.

The problam for Black here is that White can capture with check.

21.Bxb4+ Ne7 22.Na3 

Practical chess. Stockfish 13 objects, but White wants to keep his f7 pawn protected.

Remember, too, that this is a 3-minute game. That's not a lot of time for Black to unravel all of the mysteries of the Jerome Gambit.

22...Bxf1 23.Rxf1 g6 

If only it were possible for Black to play ...Kg7 and ...Rhf8, he might finally get the enemy passer under control. Alas, there is no time - and the idea does not work, anyhow.

24.Nb5 Kg7 25.Bc3+ Kh6 26.Bxh8 Rxh8 

27.f8=Q+ Rxf8 28.Rxf8 Nf5 29.Rxf5 

Simplify, simplify, simplify.

White has enough extra material to win. He removes Black's last defending piece. Giving up the exchange does not matter.

29...gxf5 30.Nxc7 Kg5 31.Nd5 f4 32.Kf2 Kf5 33.Ne7+ Ke5 34.Nc8 Kd5 35.Nxa7 Kc5 

36.Nc8 Kc6 37.Ne7+ Kd6 38.Nf5+ White won on time


Black can not protect his Kingside pawns, stop White's passed d-pawn, and defend against White's wily Knight, so perhaps the clock did him a favor.

Jerome Gambit: History Lesson



I was roaming the internet, wondering if anyone else these days was dealing with the Jerome-ized version of the Two Knights Defense, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+, a line I have occasionally referred to as an "impatient Jerome Gambit" because White sacrifices his Bishop before Black plays ...Bc5.

I came upon a pleasant surprise.

Do you remember "Battle Chess"? The early chess-playing program on a variety of platforms, featuring basic graphics and even more basic chess?

Well, there is a 2017 YouTube video of the game Doucette, Matthew - Battle Chess, NES (level 1) [1990], featuring this line of play.

If you think that the Jerome Gambit and its relatives are primative, then you will appreciate the computer treatment of this line from 30 years ago. I had to share it.

Plaing the game over here will take a lot less time then watching the video.


1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ 

4...Kxf7 5.Ng5+ Kg6 6.Qf3! 

Why the "!"? Shouldn't the move get a "?!" because of the reply 6...Nd4 ?

Matthew gets credit for knowing his opponent: early computers were serious material-grabbers. While modern programs have been mostly cured of this affliction, there is simply no way that Battle Chess can resist temptation in this game.

6...Kxg5 7.Qf5+ Kh6 8.d3+ g5 9.Qxg5 checkmate.

Awesome.

Jerome Gambit: The Proper Mental Attitude

 


A new Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+) video has just been posted on YouTube, and it is definitely worth the watch.

"Most AGGRESSIVE gambit? Jerome Gambit" by ChessGeek is inspired by GM Aman Hambleton's play (see "All In Good Fun") and shows both enthusiasm and the proper mental attitude for playing the game: objectively, some lines are clearly busted (e.g. capturing the Rook when facing Whistler's Defense) but are still the better choice, as things are so tricky/trappy that White has plenty of chances - of course, this could be said about the entire Jerome Gambit.

The video is about 9 1/2 minutes long, and if it doesn't get you even more enthusiastic about the Jerome Gambit - well, there's always the Exchange Slav that you can switch to...

Return to Pollock (Part 2)

 


The Knight sacrifice in the odds game Pollock - Rumboll, Bath, 1882 that we saw in yesterday's post was interesing enough that I searched for other game examples - not necessarily at odds - arising from the Vitzthum Attack. I was surprised that I could only find one.

Gyles, Alfred - Fox, C.
NZL-ch, Timaru, 1911

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 6.Qh5 


I have used the name "Vitzthum Attack" and "Sarratt Attack" interchangeably, as have other authors, but the games that I have seen by Conrad Waldemar Vitzthum von Eckstaedt start with this Queen move, rather than 6.Nxf7 or 7.Bxf7+, so perhaps I should start being more precise.

6...Ne5 

Probably one reason that Selkirk's suggestion (see next move), from his The Book of Chess, is so rarely seen is that it comes after this defensive error by Black. Either 6...Qf6, 6...Qe7 or even 6...0-0 would be stronger.

7.Ne6 dxe6 

As recommended by Pollock.

Bruce Pandolfini, in his Chess Openings: Traps and Zaps (1989) assesses the situation
Scenario: White sacrifices a pawn to speed development. Black has as many pieces out at White, but they are not as well disposed: two lined up on the 5th rank and the other on the edge at h6. White pierces Black's veneer with 7.Ne6!, when 7...dxe6 8.Qxe5 points out Black's disarray and attendant helplessness. White then threatens to capture on c5, g7 and h6 - any of which would put White a piece ahead. There is no defense to all three forays.
8.Qxe5 Bb4+ 9.c3 

9...dxc3 10.bxc3 Be7 11.Qxg7 Bf6 12.Qxh6 Bxc3+ 13.Nxc3 Qd4


White has two extra pieces for a pawn. He decides to give back a piece, while placing his dark square Bishop on the long diagonal. He could try, instead, 14.Bb5+ c6 15.Bb2, because 15...cxb5 would be strongly met by 16.Rd1.

14.Bb2 Qxc4 15.O-O-O Bd7 16.Qf6 Rg8 17.Rd4 Qc5 18.Rhd1 Rd8 

19.Kb1 Qg5 20.Qxg5 

Exchanging Queens does not slow down White's attack much, but he has stronger in  20.Qf3

20...Rxg5 21.f4 Rxg2 22.Ba3 a6 23.f5 b6 24.fxe6 fxe6 25.Rf1 Rg8


White now liquidates the position. This strategy may turn out to be wrong, in which case he probably would regret not playing more aggressively at move 14 (see above).

26.e5 Bb5 27.Nxb5 axb5 28.Rxd8+ Kxd8 29.Rf8+ Rxf8 30.Bxf8 c5 

In this curious position, the game was reportedly drawn.

If Black keeps his Queenside pawn structure intact and unmoved, while advancing his King along the a-file - keeping in mind that he has to be able to protect his b6 pawn if it is attacked - it looks like he may very well keep the balace.

White cannot send his King to the Kingside to create a passed h-pawn, because Black's pawns would then break through on the Queenside.

Return to Pollock (Part 1)

 


I continue to keep an eye open for games by W.H.K. Pollock, despite his dismissive attitude toward the Jerome Gambit ("Every form of the Jerome Gambit is, I believe, unsound...").

This blog has taken a peek at 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Qe2 from (among others) Pollock, W.H.K. - Vernon, J.E., Bath vs Bristol match, 1883 (1/2 - 1/2, 29).

It has presented some history of 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Bxf7+, variously referred to as the  Noa Gambit / Monck Gambit / Open Italian Four Knights Jerome Gambit, as well as a couple of Pollock's games with the line.

I recently encountered W.H.K. Pollock A Chess Biography with 523 Games, by Olipiu G. Urcan and John Hilbert, (2017), which includes an odds game by Pollock, using

[T]he Sarratt or Vitzthum Attack, a possible fore-runner to the Jerome Gambit. See "A Bridge To... Somewhere?", "Another Distant Relative?", "The Sarratt Attack", "Another look at the Sarratt Attack" and "Sarrat Attack: No Way A World Champion...".

 

Pollock - Rumboll, A.

Bath, 1882

Remove White's Knight at b1

notes by Pollock 

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 6.Qh5

6...Ne5

A more precise defense was 6...Qf6 7.O-O Qg6.

7.Ne6

This beautiful move, which wins a piece by force, is mentioned in [George H.] Selkirk's The Book of Chess but in very few, if any, more recent works in English. 

[Selkirk's suggestion came in a note to the game Pindar and Beaver, consultation vs Anderssen, Manchester, 1857 (1-0, 17). No odds were given. - Rick]

7...Bb4+

Producing a veritable vortex! It would have been better to play 7...dxe6 and the game would be about even. 

8.c3 Nd3+?

Giving away the advantage. Black could have maintained the edge with 8...dxe6! 9.Qxe5 Be7 10.Qxg7 Bf6 11.Qxh6 dxc3 12.Be3 cxb2 13.Rb1 Bc3+ 14.Ke2 Qd6

9.Bxd3 dxc3?

Best was 9...dxe6! 10.Qb5+ c6 11.Qxb4 e5 with chances for both sides. 

10.Nxg7+! Kf8 

10...Ke7 is met by 11.Qe5+ Kf8 12.Bxh6 cxb2+ 13.Ke2

11.Bxh6 cxb2+ 12.Ke2 bxa1=Q 13.Rxa1 Qf6 

13...Kg8 is met by 14.Qg4 Kf8 15.Ne6+ Ke8 16.Qg7! 

14.Ne6+ Kg8 15.e5 Qxe6 

and White mates in three moves
