The Jerome Gambit: The Eternal Question of Draws
When you play a wild and crazy opening with White like the Jerome Gambit, are you willing to settle for a draw? When you defend against such a reckless attack with Black, will you be happy splitting the point? Is a draw winning or losing a half point?
These questions are spurred by the following game.
Wall, Bill - Guest2236463
PlayChess, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6 8.Qc5
White avoids the threatened ...Nf3+, winning his Queen.
8...Qe7 9.Qd5+ Qe6 10.Qc5 Nc6
Black decides, at least for the time being, to avoid a draw by repetition. That is reasonable, as he has an "objectively" won positioni.
11.f3 d6 12.Qf2
White always has the option of flipping roles, and challenging Black to become the attacker.
12...Nf6 13. Nc3 Rf8 14. O-O Bd7 15. Be3 Kg8
16.h3
Come and get me.
16...Rae8 17.Rad1 Ne7 18. Rfe1 a6 19.a3
Attacking has its risks.
19...Nh5 20.f4 Qf7 21.f5 Bc6 22.Bd4 Nf6
Black has rearranged his pieces, but hesitates to attack.
23.Re3 Nd7 24.Rg3 Ne5 25.Rd2 Kh8 26.Re3
Perhaps spurred by the clock, perhaps by nerves, Black now decides to go for the draw.

Fascinating...

Jerome Gambit: Old Friends
The following game has a line of play that brings together "old friends" along the way to White's victory.
Wall, Bill - Guest901255
PlayChess.com, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian opening. Black wants to keep a knight off of g5, even at the cost of a tempo and the possible weakening of his Kingside.
4.O-O Nf6 5.Nc3 Bc5 6.Bxf7+
The Semi-Italian Four Knights Jerome Gambit. (Welcome, Knights.)
6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 d6
I think I have been in this position almost 20 times. More to the point, Bill has been here several times as well.
10.f4 Nc6 11.Qd3 Rf8 12.Bd2 Kg8 13.Rae1 Bd7 14.Rf3
"Jerome pawns"? Check.
Backed by White's two Rooks? Check.
Black castles-by-hand? Check.
14...Nb4
Impetuous attack on the White Queen? Check. (Oh, how we have missed you.)
15.Qc4+ d5 16.Qxb4 dxe4 17.Nxe4 Nxe4 18.Qxe4
White is a pawn ahead. The opposite-colored Bishops hint at a possible drawn endgame - but in the current middle game they will benefit the attacker.
18...Bc6 19.Qe6+ Kh8 20.Rd3 Qf6 21.Qxf6 Rxf6 22.Re7
22...Rc8
Black does not want to give up another pawn, but this move allows White to put deadly pressure on g7.

Back in the Battle Again
I have signed up for the 24-player "Italian Battleground" tournament at Chess.com with hopes that after 1.e4 e5 2.Nf3 Nc6 3.Bc4 at least a few of my opponents (we are in groups of 6 and play 5 games simultaneously) will play 3...Bc5, allowing me to unleash the Jerome Gambit.
Curiously, I have Black in all 5 of my games to start. Perhaps that will allow me to keep my Jerome Gambit plans under cover for a while.
(So far I have won one of my games, but my opponent played 3...Nf6 in our second game. No Jerome Gambit, here.)

Of course, I will share my Jeromes as they are completed.

Jerome Gambit Discovery: Success? Not Really
I was wandering the internet the other day, looking for some Jerome Gambit references that were new to me, when I decided to visit the ChessBase Live Database.
There I found the game Fejfar, Vlastimil - Chvojka, Jaroslav, CZE-Cup32 final email ICCF, 2015 which did not appear in The Database.
Success!
Not really, as you will see.
Of course, Vlastimil Fejfar is familiar to readers of this blog - see "Correspondence Play Parts 1, 2, and 3", "Climbing Sněžka" and "A Fierce Jerome Gambit Battle" for starters.
But I think there is something mixed up in the ChessBase Live Database...
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Ke7
The first clue that something might be amiss. The Database has 44 games with this position, out of 13,090 games starting 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+. That turns out to be about 1/3 of 1% - a very rare move, indeed!
Of course, Black might be "experimenting", too, but it seems unlikely that he would turn his "won" game after White's move to a slightly worse game after his own move.
5.Nxe5
Suspicious. White would have a comfortable "pull" after either 5.Bxg8 or 5.Bb3. I could see this move in a lightning game... maybe. In a serious correspondence game? No.
5...Nxe5 6.Qh5
Again, raising eyebrows. Why not the straight-forward 6.Bxg8 Qxg8 7.d4 when 7...Qc4 8.dxc5 Qxe4+ 9.Qe2 Qxe2+ 10.Kxe2 is clearly good.
Feeling adventurous? Then 6.Bb3 was the move, and after 6...Nc6 or 6...Bd4 or 6...Bb6 White could test Stockfish 9's contention that the first player has an edge.
6...d6
Strangeness from the other side of the board. Black is rated at 2295, and should have seen 6...Bxf2+ 7.Kxf2 Nxf7, with a better game, easily.
7.Qh3
No, I don't think so.
7...Kxf7
Missing something.
More likely, the "game" is bogus.
8.Qh4
No. Not even blindfolded.
8...Qe7
Consistent, but absurd.
9.Qxe7+ Nxe7
And Black went on to win - in whatever alternate universe the battle was fought.
10.h3 Be6 11.d3 Rhf8 12.Ke2 Kg8 13.Be3 Nc4 14.d4 Rae8 15.e5 b5 16.dxc5 b4 17.Kd3 Rb8
Very strange, indeed.
I went to ICCF website, looked up the event, and studied the crosstable: Fejfar came in 2nd to Chvojka, with 20.5 points to his opponent's 21.5. When I downloaded the PGN file of what appeared to be the game, however, it had only the outcome, not the moves.
I checked my copy of ChessBase's Big Database and could not find the game.
Another blow to the argument "But I saw it on the internet!"
(Years ago, when chess game databases began to proliferate, publishers were known to "seed" their databases with imaginary games, the better to use them as markers to show if others - publishers, players - later copied their work. I suppose that is one possibility, here.)

Meeting A Surprise With A Surprise
The following game shows Black unveiling a surprise line, only to be met by White's surprise. The defender continues with another surprise on move 6, but cool play makes the difference in the face of complications.
Wall, Bill - Emankcin
Playchess.com, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4
The Blackburne Shilling Gambit. White has several ways of effectively meeting the idea, including 4.0-0, 4.d3, 4.c3 and 4.Nxd4. Black's main idea is revealed with 4.Nxe5 Qg5!?.
Of course, Jerome Gambit fans also like to give the game their own twist.
4.Bxf7+
The Blackburne Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke8 6.c3 Qg5
Black plays his thematic move. It might not be as strong as 6...Nc6, leading to an even game, but it certainly gives White something to think about. The Database contains 125 games with this position; White scores 57%.
For coverage on the line in this blog, see "Surprise!", "Too Fast, Too Furious" and "A Head Scratcher".
7.cxd4 Qxg2 8.Qf3
Calmly meeting Black's play.
8...Qxf3 9.Nxf3 d6
White has an extra pawn, and although it is doubled, it is a center pawn. Black has the two Bishops. The position would seem to slightly favor the first player - but it mostly favors the player who can come up with an effective plan.
Two other lines of play:
9...Bb4 10.Nc3 d6 11.Nd5 Ba5 12.b4 Bb6 13.Rg1 g6 14.Bb2 Ne7 15.Nf6+ Kd8 16.Ng5 Rf8 17.Ngxh7 Rf7 18.d5 c6 19.Ng5

11.Ke2
Signalling that White wants his King to be active.
The one other game in The Database with this line is also complicated: 11.Nh4 Be7 12.Ng2 Bf3 13.Rg1 g6 14.d3 Kd7 15.Bf4 Nf6 16.Kd2 a6 17.Rae1 b5 18.Ne3 b4 19.Ncd5 Nxd5 20.Nxd5 a5 21.e5 dxe5 22.Nxe7 exf4 23.Rg5 Rhe8 24.Rge5 Ra6 25.d5 Rd6 26.Nc6 Rxe5 27.Nxe5+ Kd8 28.Nxf3 Rxd5 29.Re5 Rxe5 30.Nxe5 Ke8 31.h4 Kf8 32.Ke2 Kg7 33.Kf3 Kf8 34.Kxf4 Black resigned, Papaflesas - Tseatsy, FICS, 2015.
11...Nf6 12.d3 Kd7 13.h3 Bh5 14.Bf4 Re8 15.Ke3 d5
Black's strike at the center makes sense, especially with his Rook on the e-file, facing White's King; but it has the shortcoming of opening e5 for White's pieces.
16.Ne5+ Kc8 17.f3
White is in no hurry. He reinforces his center and lets his opponent come up with the next new idea.
17...dxe4 18.dxe4 c5
19.Rad1
Developing another piece. An alternative was 19.d5, creating a second connected passed pawn that would eventually help decide the game..
19...Kc7
Perhaps a time slip: Black's King walks right into a discovered check.
Instead, Black could win the exchange with 19...cxd4+ 20.Rxd4 Bc5. Stockfish 8 is not particularly concerned about this, however,
still seeing White as better after 21.Nb5 Bxd4+ 22.Nxd4. White has the open c-file for his Rook, and a pawn or two on the Queenside should prove vulnerable.
20.Nf7+ Black resigned
Play likely would continue 20...Kc6 21.Nxh8 cxd4 22.Rxd4 Bc5 23.Rc1 Bxd4+ 24.Kxd4 Kd7 when 25.Nb5!? gives Black too much to think about, e.g. 25...Rxh8 26.Rc7+ or 25...Bxf3 26.Rc7+

17...dxe4 18.dxe4 c5
19.Rad1
Developing another piece. An alternative was 19.d5, creating a second connected passed pawn that would eventually help decide the game..
19...Kc7
Perhaps a time slip: Black's King walks right into a discovered check.
Instead, Black could win the exchange with 19...cxd4+ 20.Rxd4 Bc5. Stockfish 8 is not particularly concerned about this, however,
still seeing White as better after 21.Nb5 Bxd4+ 22.Nxd4. White has the open c-file for his Rook, and a pawn or two on the Queenside should prove vulnerable.
20.Nf7+ Black resigned
Play likely would continue 20...Kc6 21.Nxh8 cxd4 22.Rxd4 Bc5 23.Rc1 Bxd4+ 24.Kxd4 Kd7 when 25.Nb5!? gives Black too much to think about, e.g. 25...Rxh8 26.Rc7+ or 25...Bxf3 26.Rc7+

Jerome Gambit: What to Do Next?
Defending against the Jerome Gambit is more than finding the right move or the right line, it is also finding the right path out of a maze of complications. It is a given that Black has a "won" game after 4 moves, but, as always, he has to go on and win that game.
In the following game the defender quickly overestimates his chances and embarks on Quixotic attack that only looks scary.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian opening. Black wants to play it safe by keeping White's Knight off of g5.
4.Nc3 Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit, leading to 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 h6, etc.
I was a bit surprised to see Stockfish 8 recommend 5.Na4, leading to an equal game.
5...Kxf7
Bypassing the piece leads nowhere: 5...Kf8 6.Bb3 Nf6 7.Nxe5 Nxe5 8.d4 Bb4 9.dxe5 Nxe4 10.Qd5 Black resigned, Wall,B - Guest2310139, PlayChess.com, 2014.
6.Nxe5+ Nxe5
It is always possible for Black to go weird in the line, but not necessarily successfully: 6...Ke6?! 7.Ng6 Rh7 8.d4 Nxd4 9.Nf4+ Kf7 10.Qh5+ Kf8 11.Ng6+ Kf7 12.Ne5+ Ke6 13.Qf7+ Kd6 14.Nc4+ Kc6 15.Qd5 checkmate, Wall,B - Guest638374, PlayChess.com, 2017.
7.Qh5+ Kf8

8.Qxe5 Qe7
Putting Black's Queen on e7 or f6 is a standard defensive setup. The question is always: what to do next?
9.Qxc7 Nf6 10.d3 Ng4
Attack! More reasonable, if less exciting, was 10...d6 11.Qxe7+ Kxe7 when the second player might have an edge. But, who wants an "edge" against a refuted opening? I mean, White has to be busted, right?
11.Nd5 Bxf2+
According to plan, even though Black should bail with 11...Bd6 12.Nxe7 Bxc7 13.Ng6+ Kg8 14.Nxh8 Kxh8 when White would have the advantage of a Rook and 3 pawns against a Bishop and Knight.
Things begin to look scary for White's King, but he will find his way to safety.
12.Kd2 Qg5+
13.Kc3 Qe5+
I don't know if Black overlooked the fact that this allowed the exchange of Queens, but he had a better move in 13...Qg6, even if it still left him worse off.
14.Qxe5 Nxe5 15.Rf1 Ng4
16.h3 Black resigned
Black will lose a piece after all.
