Jerome Gambit: More Fun Quick Finishes

Some evenings I work late into the night, researching and analyzing, trying to find the elusive path to bringing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) a step or two further away from "just another refuted opening" and a step or two closer to being a "real" opening. (See "Jerome Gambit: Pinocchio" and "Jerome Gambit: Velveteen Rabit Part 1".)

Then, in the next morning's email, I get another handful of games with notes like "This is my first Jerome Gambit, ever, and I totally crushed the guy!" and I realize that the Jerome is not about finally becoming a boring, normal opening.

The Jerome Gambit is about playing chess and having fun.

So - here are some more quick hits that recently arrived.

The checkmate in the following game never gets old. We have seen this kind of thing before, and we will, no doubt, see it again.

The Jerome Gambit can inspire the sacrificial tendency in other openings, too. Jerome Sicilian, anyone?

Here, the Petroff Defense, by transposition, meets the Jerome Gambit. Any guess which wins?

My daughter bought me Murray Chandler's How to Beat Your Dad at Chess. I am sure she meant no harm. The following game could have wound up in that book. I hope the son didn't get grounded.

Finally, a Jerome Gambit that ended when the defender realized that his defense hadn't really defended.

Jerome Gambit: Danger!

In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Black's King is drawn into the wilderness, where he has a slim path to safety - but he misses it. White demonstrates the danger.

4...Kxf7 5. Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.Nc3 Qf6

Black's Queen joins the defense, but the King is going to be drawn into danger, anyhow.

9.d4 Bxd4 10.Nb5+ Kc5 11.Nxd4 Kxd4 12.Be3+ Kc4 13.Qh5 Kb4 

The King is all alone and at risk.

He needed to play 13...Kb5, instead, and focus on returning home. For example, if White then tried 14.f4, there was the helpful 14...d6, giving a way off the battlefield, via c6 and d7. He shouldn't worry about 15.fxe5 Qxe5, as he can afford to return the piece and remain a piece ahead. 

14.Qe2 

Cutting off retreat. White now focuses on checkmate. It is well worth playing through the following moves, to see what choices the attacker had, and what chances the defender did not.

14...Qc6 15.c3+ Ka4 16.b3+ Ka5 17.b4+ Ka4 18.Qd1+ Kb5 19.a4+ Kc4 20.Qd4+ Kb3 21.Rb1+ Kxa4 22.b5+ Qc4 23.Rb4+ Black resigned

Black will lose his Queen, and then his King.

Jerome Gambit: Catching Up

With many new chess players discovering the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7) and this blog, there is an opportunity to learn a great deal more about the opening, the person who created it, and the people who play it.

But, do you have to go back to the beginning - "Welcome!" - and read almost 3,000 blog posts?? No, of course not.

If you have an interest in a particular player, or a particular topic, or even a particular move, you can always use the "Search This Blog" function, on the right. Searching a string of moves, say "4.Bxf7+ Kf8 5.Bxg8 Kxg8" can also be effectively done with general search engines like Google or Bing, which will turn up links to this blog.

You can also visit the "Retro" page, which has easy links to pages of interest, with lots of information.

Or you can take the multi-part Jerome Gambit quiz, starting here.

There is a page, with links, that discusses the timeless, but relevant question, "Is the Jerome Gambit playable?"

Finally, for a deep dive into the Jerome Gambit, you can read the multi-part article that I wrote for Stefan Bücker's chess magazine, Kaissiber. He tried and he tried and he tried to make the article fit, but I think the Jerome was a bit too irregular for him.

Jerome Gambit: More Mysteries

Jerome Gambit games keep pouring in...

Another mystery (see "Jerome Gambit: Ghosts in the Defense") arrived the other day, followed, a few days later, by, yet, another. I want to share the games, and some perspective. I have made the name of the players of the Black pieces anonymous.

1. e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 

Black resigned

What was going on??

Three things, about the world of the Jerome Gambit.

I wanted to share something from GM Nigel Davies' fantastic book, Gambiteer I.

“Having examined literally thousands of club players’ games over the years, I have noticed several things: 

1) The player with the more active pieces tends to win. 

2) A pawn or even several pawns is rarely a decisive advantage. 

3) Nobody knows much theory. 

4) When faced with aggressive play, the usual reaction is to cower.”

That might explain the defender's behavior.  Meanwhile, to explain the attacker's attack, some input from Geoff Chandler, chess player, coach, and raconteur. I quote from one of his posts

Here is a one-move blunder table showing how severe the blunder needs to be in a game between two players of the same grade.

All players should be able to spot their opponent leaving a mate in one on. 

A 1200 player should win if an opponent blunders a Queen or a Rook. But not necessarily if they pick up a Bishop or Knight. 

1500 players often convert piece-up games into a win, but this is not the case if a pawn or two up. 

An 1800 player usually wins if they are two pawns up. 

In a game between two 2000+ players a blundered pawn is usually enough to win.

I think that Chandler's blunder table can be applied to time limits, as well. In correspondence play, a little material means a lot. In blitz or bullet play, though - sacrifice away!

Finally, an assessment from the Jerome Gambit player, himself, concerning the first game, although it could apply to the second as well.

The game started off with a normal Jerome Gambit. After ...Nxe5 I decided to go for the Queen check variation rather than the theoretically more solid d4 move forking the bishop and knight, mainly because I consider it to be a more active way to attack the king and eventually gain compensation for the sacrificed pieces. As soon as I checked the king with my queen, black started burning some serious time which suggests that this gambit might have caught him by surprise which is in my opinion the biggest advantage of the Jerome Gambit together with its fierce attack on the king side. As you can see in the game I sent you he eventually burned approximately 1 minute and 25 seconds, only in his sixth and final move. Which shows that the spontaneous nature of the gambit is its main advantage, as if this had been a quick 3 minute blitz game where this gambit is originally intended to be played, he would have already used half of his time in his first six moves. My opponent was probably considering the best way in which he could get out of check. He eventually decided to block the queen's check with his knight going for ...Ng6 probably because he was scared of playing something like ...g6 which would run into Qxe5 delivering a fork on the bishop and rook, or protecting his knight with a move like ...Ke6 which would expose his king in a very dangerous way. After my opponent played ...Ng6 both protecting his knight and blocking the check I decided to play Qd5+! which is as you already know the theoretical novelty that GM Aman Hambleton introduced in his video about the Jerome Gambit which has the idea of inviting black to play either Kf8 or Ke7 which allows white to capture the bishop with another check to continue his attack and to stop black from developing. Surprisingly enough, shortly after I played this move my opponent resigned because despite being objectively better, as he was two pieces up, he thought that he was losing because of the speed in which I played my moves which suggested that the Jerome Gambit was either some kind of tactic which he had blundered into or a very strong attack which I had brought prepared from home. The moral of the story is that he resigned a six move game being two pieces up and with plenty of time on the clock solely because of the speed of my moves and the position of his king...

Jerome Gambit: Ghosts in the Defense

Recently I received the following Jerome Gambit game. At first, I did not know what to make of it.

Anonymous - Anonymous
5 3 blitz, lichess.org, 2020

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Nf6 9.Qxd8 White won

That was kind of strange... Except, a couple of days later, the same line played out in another game, a 3 0 blitz, although the defender struggled on for a dozen more moves before resigning.

How to explain Black's 8th move? A weak chess player? A hurried-by-the clock chess player? A scared-by-the-Jerome-Gambit chess player? An overconfident-and-therefore-inattentive chess player?

I finally decided that I had been onto something when I wrote "Half a defense is worse than none at all..." a decade ago.

My guess is that 7 out of 10 players who have ever heard of the Jerome Gambit had been exposed to Amateur - Blackburne, London, 1884: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.c3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4#

What if the defenders in both recent games remembered only a part of Blackburne's defense, or remembered it incompletely?

"Hmm... silly Jerome Gambit... accept the sacrificed Bishop... accept the sacrificed Knight... give back a Rook... trap the enemy Queen with my Kight - No, wait, I was supposed to play 8...Qh4 first!!"

I found an earlier game with even more pain.

This time the Queen is trapped, but take note of White's next move. Meanwhile, Black repeats Blackburne's killer attack on the King, including sacrificing another Rook, and his Queen. 

10.Nc3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4+ 15.Nxe4 Black resigned

White's Knight on c3 - instead of a pawn, as the Amateur played against Blackburne - ruined Black's fireworks display.

So, is 10.Nc3 White's way out of his Blackburne nightmare?

Actually, a game played at the end of May of this year said: No!

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.Nc3 

10...Bh3 11.Qxa8

Best might have been 11.Qxf6+ Kxf6 12.gxh3 Qxh3, with a Rook, a Knight and a pawn for his Queen, although Black would still be better.

11...Qg4 12.g3 Qf3 White resigned

Surprisingly enough, Grandmaster Larry Evans had discussed this line in his Chess Catechism (1970). He gave 10...Bh3 a "!". In discussion on this blog, "GM Larry Evans and the Jerome Gambit", Bill Wall pointed out 10...Ng4, that elmflare played, above.

(Is 10.Qd8!? the real solution to White's trapped Queen? That's a long story, and one that will have to wait for another day.)

Jerome Gambit: And, In Time, The Win

In the following game, Black denies his opponent the wild attack that often comes with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). White soon has the better game, and, in time, the win.

M4G1CK - HubRekt

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

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

Now, Black has 7...d6, the Blackburne Defense (named after the game Amateur - Blackburne, London, 1884, in which Blackburne sacrificed 2 Rooks and his Queen), or 7...Qe2, Whistler's Defense (named after Lt. G. N. Whistler, who played it in a correspondence match against Jerome).

Instead, he chooses what I have begun to call the Jerome counter-gambit.

7...Bxf2+ 8.Kxf2 Qf6+ 9.Qxf6+ Kxf6 

The good news for White is that he is no longer down a couple of pieces - in fact, he is up a pawn.

The bad news is that he doesn't have a dashing, smashing attack. He will have to grind out the win, starting in a Queenless middlegame.

10.Rf1 Kg7 11.Kg1 d6 12.d4 Nf6 13.Nc3 Re8 14.e5 dxe5 15.dxe5 Rxe5 16.Bf4 Rf5 17.Bxc7 Rxf1+ 18.Rxf1 Bg4 

White plays on without risk.

The only "danger" he faces is the possibility of a drawish Bishops-of-opposite-colors endgame, should the Knights and Rooks come off the board. That is not going to happen, though, as he is ready to win a piece.

19.Be5 Rf8 20.Nd5 Re8 21.Bxf6+ Kh6 

White has enough to win. It will take a few more moves.

22.Rf4 Bh5 23.g4 g5 24.Rf5 Bf7 25.Bxg5+ Kg7 26.Bf6+ Kh6 27.Bg5+ Kg7 28.h4 Bxd5 29.Rxd5 h6 30.Bd2 Re4 31.Bc3+ Kh7 32.Rd7+ Kg6 33.Rd6+ Kh7 34.Rd7+ Kg8 35.Rg7+ Kf8 36.Rg6 h5 37.gxh5 Rxh4 

You can see how the game is going to end.

38.h6 Kf7 39.Rg7+ Kf8 40.h7 Re4 41.Rxb7 Rg4+ 42.Kf2 Rh4 43.h8=Q+ Rxh8 44.Bxh8 Kg8 45.Rxa7 Kxh8 

46.Rd7 Kg8 47.c4 Kf8 48.c5 Ke8 49.Rd1 Ke7 50.c6 Ke6 51.c7 Ke5 52.c8=Q Ke4 53.Qc4+ Kf5 54.Rd5+ Ke6 55.Qc6+ Ke7 56.Rd7+ Ke8 57.Qc8 checkmate

Slow and steady wins the race. Nice.

Jerome Gambit: Computers Can Be Both Helpful and Annoying

The following Jerome Gambit blitz game arrived with notes from the chess site's computer. Often, the computer analysis is helpful. Sometimes, however, it just highlights the differences between silicon and human play.

CasualGames4ever - lankesh1941
10 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

The lichess.org analysis engine labels this move a "Blunder". Well, yes, technically it is. However, in human vs human blitz play at the club level, it is more of an invitation to interesting play!

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

The engine labels this an "Inaccuracy", which is a bit harsh. The move is played frequently and keeps Black's piece for two pawns advantage.

7.Qd5+ Ke7 8.Qxc5+ d6 9.Qe3

9...Be6 

The know-it-all chess engine calls this a "Blunder". It allows White to play 10.f4, with the threat of f5, forking Black's pieces.

10.d4 Kf8 11.Nc3 12.f4 Re8 13.O-O Bf7 

Black says: Come and get me!

Any Jerome Gambit player would oblige.

14.f5 Nh4 15.Qg3 h6

Planning something drastic.

16.Rf4 g5

This would work, if White couldn't capture en passant.

17.fxg6 Nxg6 18.Qxg6 Qe6 19.Qxe6

The cranky computer doesn't like this move, but it is perfectly reasonable: White is playing a blitz game, and he is happy to move on to a Queenless middlegame two pawns up.

19...Rxe6 20.d5 Rg6 21.Nb5 c5 22.Nxa7 Nf6 23.Nb5 Rhg8 24.Nxd6 

Cold-blooded. White's Knight has been collecting pawns, even though this means that his King will have to take a vacation on the Queenside. Perhaps the clock was beginning to influence play?

24...Rxg2+ 25.Kf1 Rg1+ 26.Ke2 Bh5+ 27.Kd3 Rd1+ 28.Kc4 Ke7

White is still winning, but he is no longer comfortable.

29.Kxc5 

A slip, as Black can now kick the enemy King away with 29...Nd7+, and then grab the Knight. Instead, 29.Nf5+ Kd8 30.Ne3 would have consolidated his position and won more material.

It definitely feels like the clock is affecting both players, now.

29...Rgg1 

To win the Bishop, of course.

30.Nc8+ Kd7 31.Rxf6 Kxc8 32.Be3 Rxa1 33.Bxg1 Rxg1 34.Rxh6 

Whew! White now has 5 pawns for Black's extra piece. Push those pawns!

34...Bd1 35.e5 Bxc2 36.e6 Rg6 37.Rxg6 Bxg6 38.d6  Bf5 39.Kd5 Bh3 40.a4 Bg2+ 41.Ke5 Kd8 42.b4 Bc6 43.b5 Bf3 44.a5 Be2 45.a6 bxa6 46.bxa6 Bxa6 

47.h4 Ke8 48.h5 Bd3 49.h6 Bc2 50.Kf6 Kf8 51.d7 Black resigned

Another victory for the "Jerome pawns"!
