Jerome Gambit: Giving Black "A Second Chance"

You sit down to a game of chess, you are planing on using the Jerome Gambit - but your opponent opts to play the Two Knights Defense. What to do?

We have looked at this dilemma a number of times in the past (see, for example, "Jerome Gambit vs Two Knights Defense", parts 1, 2, 3 and 4).

The following game and its notes show that sometimes giving Black a "second chance" can return the game to desired channels. The focus is upon the games of a player who has dealt with this issue many times.

The position is beginning to look like a "regular" Jerome Gambit position, if we go ahead and now add 7...Bxd4, transposing, i.e. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Nf6 8.0-0

12.Nc3 c6 13.Be3

White develops and hopes to take advantage of Black's King's position. "Objectively" Black is still better, with a piece for a pawn; but the d-pawn blocking the Bishop which hems in the Rooks is always an ominous sign...

13...Ne5

Instead, 13...Qe5, looking to exchange Queens and reduce the danger of an attack on his King, might have been more prudent.

14.Rae1 Neg4

Black is spending too much time moving the Knight. Perhaps he can not find a plan of play. Stockfish 8 gives a subtle line that leads to an advantage (a pawn) for White, but which has plenty of play (Black has Bishop vs Knight and more central pawns): 14...b6 15.Bf4 Qxc5 16.Qxc5+ bxc5 17.Rxe5 Kf7 18.Rxc5 Re8 19.Be5 Bb7 20.Bxf6 Kxf6 21.f3 d6 22.Ne4+ Ke7 23.Rh5 h6 24.Rd1 Rad8 25.Ra5 a6 26.Kf2 c5 27.c3 g6 28.h3 Rf8 29.Nd2 Rf6 30.Nc4

15.Bf4

The benefit of pursuing development while the opponent dithers. White's Bishop not only exposes a Rook attack on the enemy Queen, it eyes the fantastic d6 square.

15...Nd5

The simplest response - 15...Qf7, withdrawing the Queen to a safe square - is the best, although then White would have the powerful 16.Bd6+ as a reply. In the excitement, Black seems to have forgotten about Her Majesty.

16.Nxd5 cxd5 17.Rxe7 Black resigned

Checkmate is coming.

From the Corner - Smiling

It is hard to mention the chess wise guy Geoff Chandler without thinking about the following game that he posted, years ago, on his "Chandler Cornered" site

Anon - Anon
Edinburgh Congress

1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d4 d5 6.Bf4 Be7 7.Nc3 Nf6 8.Nb5 Bb4+

Geoff noted

Black played Bb4+ with the idea of playing Ba5 covering c7.
Whilst White was pondering on his next move Black suddenly stated:
"I thinks It's checkmate!"
And it was!!!
Before the start of the game neither player had noticed that the Black King and Queen were on the wrong squares.

(Okay, that was a Petroff Defense, not a Jerome Gambit. If you feel cheated, don't worry, I have you covered: check out Geoff's legendary "Mars Attacks!") 

Tidying Up - Or Messing Up?

Recently I was looking through long-time friend of this blog IM Gary Lane's 2012 "Trash or Treasure?" column, part of his at "Opening Lanes" efforts at Chess Cafe.

(Actually, I was looking at an old pdf file, stored on my phone - a phrase that would probably have been nearly meaningless when I first started this blog.)

I spotted some apparent confusion related to a Jerome Gambit game, and as I may have had a hand in causing it, I thought I'd try to do some unraveling.

From "Trash or Treasure?" 

...Finally, Mr. Kennedy pointed out a fairly recent game played by Scottish player Geoff Chandler. I have never met him, but I do know that Mr. Chandler has an excellent sense of humour and his old chess blog at Chandler Cornered was zany, thought provoking, and usually very funny. Therefore, the following game looks like a fabrication, but I am happy to be corrected in the future. Here is another Jerome Gambit game that is spectacular as always!

Chandler, Geoff - Dimitrov Todor

Blitz, Edinburgh, 2004

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

This opening is ideally suited to blitz where you don't care whether you win or lose, but want to play something memorable.  

6...g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.Qd8!

Geoff is a decent club player and could have found this himself if the game was really played.* I still think it was more likely he was following the advice given in the previous Blackburne game, which has been copied up to this point. However, I did look up his old blog and found this comment "I recall about a year ago Todor and me had a dozen or so games playing 4.Bxf7+ at 5 minute chess in Bells." If you think he played a game inside an actual bell, then think again. He is referring to his chess club hosted at a local bar.  

10...Bh3 11.Qxc7+ Kg8

Here IM Lane gives 12.gxh3 and says

Instead 12.Qxb7 is winning, because12...Qg4 can be met by 13.Qb3+! (13.Qxa8+ Kf7 14.Qb7+ Kf8 15.e5? White should keep on checking, but this winning attempt backfires spectacularly upon 15...d5 and it turns out that Black wins.) 13...Kg7 Qxh3 and it is time for Black to put the pieces back into the box.  

Then 12...Qxh3 13.Qxb7 Qg4+ A draw by repetition beckons, but Mr. Kennedy assures me that Geoff went on to win.

 Actually, the game continued 12.Qxb7 Qg4 13.Qb3+ Kg7 14.Qxh3 and according to Chandler, White won.

How did the mixup in the moves of the game occur? I could have jumbled them when I emailed the game to IM Lane - if I actually sent it, as I can't find any record of that amongst our correspondence. (Gary might have made the slip, but is that likely? He's the professional, I'm the amateur.)

Anyhow, the Chandler - Dimitrov game and analysis can get pretty messy, so perhaps that was part of it.    

In support of that possibility, and a possible clue, it is worth looking at "Updating the Blackburne Defense (Part 2)" where I reference, among a number of things, Dennis Monokroussos's thoughts from about 7 years earlier about Amateur - Blackburne, London, 1884, after 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 

Dennis M's Chess Site

...But now, here's the puzzle. After 9...Nf6, Black has a substantial lead in development and several well-placed pieces ready to commence a feeding frenzy on the White kingside, yet had White found 10.Qd8, pinning the Black Nf6 to the queen on h4, it would have been Black needing to fight for his life! The following might be best play for both sides: 10.Qd8! Bh3 11.Qxc7+ (11.Qxa8? Qg4 12.g3 Qf3 forces mate) Kf8! (11...Kg8? 12.Qxb7 Qg4 13.Qb3+ and 14.Qxh3) 12.Qxb7 Qg4 13.Qxa8+ Kf7 14.Qb7+ Kf8 14.Qa8+ with a draw by perpetual check.  

When I first saw this game and was told about 10.Qd8, it seemed to me that Black just had to have something, but neither I nor my silicon friends have succeeded in proving a win or even an advantage for Black. Can any of my readers find something better for Black?

I can sympathize with Dennis - how can Black not win against the Jerome Gambit?? In a responding comment on his blog I shared

The line gets some analysis by Geoff Chandler and Todor Dimitrov on the former's hilarious website, Chandler Cornered http://www.chessedinburgh.co.uk/index.htm
It goes like this. (Notes by Chandler.)

10.Qd8 Bh3 Threatening simply Qg4 and Qg2 mate. 11.Qxc7+ Kf8 This is best. [In my Game v Todd he played the natural 11...Kg8 which allows a check on b3 12.Qxb7 Qg4 13.Qb3+ Kg7 14.Qxh3] 12.gxh3 forced [If 12.Qxb7 Qg4 13.Qxa8+ Kf7 (13...Kg7 14.e5 d5 15.exf6+ Kxf6 16.Qxd5) 14.e5 d5 15.e6+ (15.Qb7+ Be7 16.e6+ Kg7 17.Qxe7+ Kh6 18.d4+ Kh5) 15...Kg7 16.Qb7+ Kh6 17.d4+ Kh5 and Black mates on g2] 12...Qxh3 This appears to be the best. It keeps the attack rolling and keeps the draw in hand. Remember we are seeing if 10.Qd8 beats the Blackburne line. 13.Qxb7 Ng4 [Or 13...Qg4+ and ...Qf3+ drawing.] 14.Qxa8+ Kg7 15.Qb7+ Kg8 16.Qc8+ Kg7 17.Qd7+ Kg8 18.Qe8+ Kg7 19.Qe7+ Kg8 Black has to allow the draw else 18.Qe8+ Kg7 19.Qf7+ kh6 10.d4+ wins. So it appears 10.Qd8 draws.

Note in the above that the conclusion is that the game is drawn -- the same conclusion as you came to, although the particular line you give (12.Qxb7 instead of Chandler and Dimitrov's 12.gxh3) seems to tilt toward White.

In a later post Monokroussos added

(2) In my main line, Kennedy, citing analysis by Geoff Chandler and Todor Dimitrov, varies from my 12.Qxb7 with 12.gxh3, showing that it likewise draws after 12...Qxh3 13.Qxb7 Qg4+ 14.Kh1 Qf3+ etc. or 13...Ng4 14.Qxa8+ etc. (Note that Black can't escape the checks with 14...Ke7 15.Qb7+! Kf6?? [15...Kd8/e8/f8=] because of 16.e5+ followed by 17.Qg2.) 

(3) Chandler & Dimitrov also mention 12.Qxb7 and suggest it loses, but the culprit is not 12.Qxb7 but their 14.e5?, after which Black has a forced mate. 

Very interesting and I'm grateful to Kennedy for his comment...but my dream remains unfulfilled - can't Black win after 10.Qd8, somehow?

Readers, is this confusing enough for you? Above, I quote Monokroussos quoting me quoting Chandler...

I have put the moves to Chandler - Dimitrov, cited by Chandler, above, in italics. The move 12.gxh3, which IM Lane gives as part of the game, is actually part of Chandler's analysis after 11...Kf8, not 11...Kg8, as played in the game - although Chandler says in his note that the move 12.gxh3 is "forced" which may have made it look like it was played.

I muddied things even more by referring, in my comment to Monokroussos, to "Chandler and Dimitrov's 12.gxh3" - the move was from their analysis, as presented by Chandler, above, not their game; andy by referring to 12.Qxb7, the actual move in the game, as "the particular line you give". Monokroussos seems to catch this, as indicated in his (2) note in the later post.

By the way, Monokroussos is right in note (3) in correcting Chandler's analysis (which I had provided) that after 10.Qd8 Bh3 11.Qxc7+ Kf8 12.Qxb7 White does not lose - after 12...Qg4 13.Qxa8+ Kf7 the move 14.e5 is "the culprit... after which Black has a forced mate". Instead, 14.Qb7+ Kf8 15.Qa8+ draws by repetition - as Monokroussos mentioned in his first post, after "...Now here's the puzzle." 

Still, Monokroussos doesn't escape completely. The later post, note (2), above, gives the sideline 12.gxh3 Qxh3 13.Qxb7 Ng4 [instead of 13...Qg4+, drawing] for Black, suggesting that after 14.Qxa8+ etc. the game is drawn as well - but White has, instead of grabbing the Rook, the forced Queen exchange after 14.Qb3+ (how un-Jerome-ish) 14...Qxb3 15.axb3 which leaves him a Rook and 3 pawns better.

Ah, yes, now everything now is as clear as... trash. 

(*- Chandler commented in Chandler Cornered about 10.Qd8 "This is my over the board improvement that I have since learnt was first suggested in 1951." I had told Chandler that P. Wenman mentioned the move in his Master Chess Play (1951). I later learned that the move had been played in Harris, S - Quayle, E., correspondence, 1944, although, of course, the move had been first suggested in the August 1885 issue of the Brooklyn Chess Chronicle.)

Jerome Gambit: No Mercy

In some amateur sports leagues a game will be ended under the "mercy rule" if one team is significantly ahead of its opponent (i.e. unlikely to lose under normal circumstances). Such is not the case in chess - you can have a better position on the board for 18 moves, say, and resign after the 19th. As in the following game.

10.Qe3 Rf8 11.O-O-O Nc4 12.Qd3 Nxd2 13.Rxd2 Kg8

Black has castled-by-hand and has a piece for a pawn. If he keeps on making good moves, he will collect the full point.

14.e5 Ng4 15.exd6 Nxf2 16.Qd5+ Kh8 17.Re1 Bd7

Black has to keep his eye on White's pawn at d6, but with an extra piece for a pawn, he is doing well. Still, it is a complicated position. How should he continue?

18.Re7 Rf5 

Protecting the pawn at c5 and attacking the enemy Queen.

19.Qxb7 Black resigned

Wow! Black's Bishop is threatened, and the only square that even looks "safe" allows White's pawn to advance, 19...Be8 20.d7 Bf7 21.Qxa8!? Qxa8 22.d8/Q+ Qxd8 23.Rxd8+ Bg8 24.Ree8 - not so safe for the Bishop after all.

Best for Black seems to be giving up the Bishop for some play, 19...Qf8 20.Qxd7 Ng4, but after 21.Qe6 White will have centralized pieces and a couple of extra pawns, especially the dangerous on at d6.

Jerome Gambit: Choosing Better or Worse?

Sometimes a computer chess engine will recommend a line of play which is "objectively" better than an alternative that a human might choose. Yet there might be good reasons to choose the "worse" line of play, if it is tricky and has some traps. See the note to Black's 7th move.

On the other hand, sometimes "human" moves fall short, as well. See the note to Black's 9th move.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Nf6 

Black has so many ways to return some of the sacrificed material!

7.dxe5 Bxf2+ 

This move appears in 10 previous games appearing in The Database, with White scoring 70%. However, that is not the whole story.

Stockfish 8 recommends, instead 7...Qe7!?, which does not show up in any of the games in The Database. White does best to grab a second piece with 8.exf6, but then is faced with how to answer 8...Qxe4+.

Probably best is 9.Kf1 which we will come back to in a moment, after first examining the messy 9.Be3.

Black can respond to this latter move with 9...Bxe3 10.fxe3 Qxe3+ 11.Qe2 when the exchange of Queens would leave him a pawn up. Or he could go for 11...Qc1+ when 12.Kf2 is the offer of a Rook, i.e. 12...Qxh1, although it does not turn out well for the second player: 13.Qe7+ Kg6 14.Qxg7+ Kf5 15.Nc3 Qxh2 (taking the other Rook with 15...Qxa1 leads to mate) 16.Rf1 and Black's position is miserable as he has only 16...Qf4+ to help him extend the game, but 17.Kg1 Qxf1+ 18.Kxf1 still is hopeless. After visiting c1, Black's Queen should return to f4 with check, and eventually wind up a pawn ahead, again. 

Going back to the computer-recommended 9.Kf1, Black responds with 9...Qf5 and after 10.Qf3 Qxf3 11.gxf3 d5!? he is a bit better (better pawn structure, two Bishops, equally insecure Kings) even if White finds 12.h4!? to prevent ...Bh3+, forcing his King into the center where the enemy Rooks can roam.

By the way, Bill dispatched 7...Nxe4 quickly in a couple of games: Wall,B - NN, lichess.org, 2016 (1-0, 16) and Wall,B - TenAndOnly10, lichess.org, 2016 (1-0, 21)

8.Kxf2 Nxe4+ 9.Kg1 Rf8 

Preparing to castle-by-hand, a standard defensive plan in the Jerome Gambit; but overlooking the Queen check at d5 - odd, in that his Bishop sacrifice seemed aimed against that same eventuality.

Instead, 9...d5 would be about even, although Bill has a couple of wins against the move:  Wall,B - MyDrunkAccount, lichess.org, 2016 (1-0, 20) and Wall,B - Szachowski, playok.com, 2017 (1-0, 20). 

10.Qd5+ Ke8 11.Qxe4 Rf7 12.Nc3 d6 

This hurries Black's demise.

Jerome Gambit: Paths Off of Paths

The Jerome Gambit is an opening that is clearly "off the beaten path". Yet, in pursuing it, players often find themselves further afield - and it is good to know about some of those side paths as well.

It is clear in the following game that the defender was not prepared to have the game "Jerome-ized".

Wall, Bill - Guest761989
PlayChess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 4.Bxf7+ 

With his third move Black imagines a quiet win of the "minor exchange" with 4.Bb3 Nxb3. He is too hopeful, as White has, instead, 4.Nxe5, and after 4...Nxc4 5.Nxc4 d5 6.exd5 Qxd5 7.Ne3 White is a pawn up, and Black has little to show for it.

However, players familiar with the Jerome Gambit will be tempted to play the Bishop sacrifice on move 4, giving Black a very un-quiet game.

4...Kxf7 5.Nxe5+ Ke6 6.d4 d6

White has two pawns for his sacrificed piece, but his play against Black's King gives him adequate compensation.

7.Qg4+ Ke7 8.Qg5+ Ke8 

Better is 8...Nf6, although after 9.Nf3 Nc6 10.e5 dxe5 11.dxe5 Kf7 12.exf6 Qxf6 White would have a small advantage.

9.Qxd8+ 

It is important to note that in the 4 earlier games in The Database, White had tried 9.Qh5+. Best play would continue 9...g6 10.Nxg6 Nf6 11.Qh4 hxg6 12.Qxh8 Nxe4 When White would have a Rook and two pawns against a Bishop and a Knight. This is a small edge for White, and I can see why Bill chose a different path: His active Knights will go after the slumbering Rooks in the corners!

9...Kxd8 10.Nf7+ Ke8 11.Nxh8 g6 12.Nc3 Bg7 

As indicated.

13.Nd5 c6 14.Nc7+ Black resigned

Black will lose his other Rook, and while he will gather in the Knight at h8, he will have a very difficult time catching the other one, leaving him down a couple of exchanges, plus a pawn or two.

The Delayed Pie-in-the-Face

The difference between a very strong counter in the Jerome Gambit at move 6 and an ineffective defensive line (the same move one tempo later) shows the problem with delaying an active riposte. 

Wall, Bill - Guest6766281
PlayChess.com, 2017

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

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb6

Black can decide which piece to save, the Bishop or the Knight. The text is a reasonable line.

Of course, Black's strongest response is to ignore both of the pieces and play 6...Qh4!?, what I have referred to as a pie-in-the-face variation.

7.dxe5 Qh4

A delayed pie-in-the-face? Tossing pies is very much a part of slapstick humor - and timing is always critical in comedy.

This line has been faced by Jerome Gambiteers chessmanjeff, frizerkaHR, GOH, HauntedKnight, jfhumphrey, ndrwgn, stretto, Wall and yorgos. As a group, they have not been impressed.

8.Qf3+ Ke7

A slightly better retreat is 8...Ke8, e.g. 9.Nc3 (9.O-O Ne7 10.Nc3 Rf8 11.Qe2 g5 12.Be3 Ng6 13.Nd5 Kd8 14.Qd2 h6 15.Bxb6 axb6 16.Nxc7 Kxc7 17.Qd6+ Kd8 18.Qxg6 Re8 19.Qxb6+ Ke7 20.Qf6 checkmate, Wall,B - Guest2616286, PlayChess.com, 2017) 9...Ne7 (9...Bxf2+ 10.Qxf2 Qxf2+ 11.Kxf2 Nh6 12.Nd5 Ng4+ 13.Kg3 Kd8 14.Bg5+ Nf6 15.exf6 h6 16.fxg7+ Ke8 17.gxh8=Q+ Kf7 18.Rhf1+ Kg6 19.Qxh6 checkmate, Wall,B - Shillam, lichess.org, 2016) 10.g3 Qh3 11.Be3 d6 12.Bxb6 cxb6 13.exd6 Ng6 14.Nd5 Qd7 15.Nc7+ Kd8 16.Nxa8 Qxd6 17.Rd1 Ne5 18.Rxd6+ Ke7 19.Qc3 Kxd6 20.Qd4+ Ke6 21.Nc7+ Kf7 22.Qxe5 Rd8 23.Nb5 Bg4 24.Qf4+ Kg8 25.Qxg4 a6 26.Qe6+ Kh8 27.Nd6 Rb8 28.Nf7+ Kg8 29.Nh6+ Kh8 30.Qg8+ Rxg8 31.Nf7 checkmate, Wall,B - Itboss, lichess.org, 2016.

Or 9.O-O Nh6 10.Nc3 Rf8 11.Nd5+ Kd8 12.Qxf8 checkmate, Wall,B - Guest2293428, PlayChess.com, 2017.

9...Nh6 10.Nd5+ Kd8

Once again, e8 is the better square for the King.

11.O-O

White also has the sneaky 11.h3!? threatening g2-g3, winning the Queen. Black could escape by returning a piece for two pawns, i.e. 11...Bxf2+ 12. Qxf2 Qxe4+ but White would be better.

For the record, 11.g3?! directly could be answered by 11...Qg4 and White does not gain much by exchanging Queens, while he would lose time if he movee his Queen to avoid the swap.

11...Bd4

Looking to grab the pawn at e5, but he is overlooking a few things. He could have maintained an even game with 11...c6 12.Nxb6 axb6.

12.g3 Qh3

Why was e8 the better square for Black's King to retreat to (as suggested in the note to move 10)?

Why was the Black Bishop's trip to d4 problematic (as mentioned in the note to move 11)?

Why couldn't Black retreat his Queen to g4 (as in the note to move 11), instead of h3?
