Jerome Gambit: Yet Another Smother

Here is a final game ending in a "smothered mate". That it was played at lightning speed makes it a bit special. Once again, Black counter-sacrifices a Bishop, without proper compensation.

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 

The so-called Abrahams Jerome Gambit.

3...Kxf7 4.Nf3 Bxf2+

Returning the sacrificed piece in this way is more of a psychological move than anything else. It is not counted among the refutations of the opening.

The Database has 210 games with this position. White scores 64%

5.Kxf2 Nf6 6.Rf1 Nxe4+ 7.Kg1 Rf8 8.c3 Kg8

Move, move, move. Kings are safe. Great. Move, move, move.

9.Qb3+ d5 10.d3 Nf6 11.Nxe5 c6 12.c4 Qc7 13.Bf4 Ng4 14.d4 b5

15.cxd5 Nd7 

Oops.

16.d6+ Kh8 17.dxc7 Nb6 18.Nf7+ Kg8 19.Ng5+ 

Missing it the first time (19.Nh6+) but White has just won a Queen, so maybe he was thinking more prosaicly. He figures it out a moment later, though, and when Black doesn't snap off the Knight at f7...

19...Kh8 20.Nf7+ Kg8 21.Nh6+ Kh8 22.Qg8+ Rxg8 23.Nf7 checkmate

There we go.

Jerome Gambit: Another Smother

Here is another "smothered checkmate". It is interesting that it is the computer program that falls victim to the Queen sacrifice and mate.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.Bxf7+

Transposing to a "modern" (vs "classical") version of the Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6, etc. The Database has 1,065 games with this position. White scores 41%.

5...Kxf7 6.Nxe5+ 

Now White decides to go "classical" after all. It is as if the game started 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 and then continued 6.0-0 Nf6 7.d4 (or 6.d4 Nf6 7.0-0). If LuigiBot has a "book" it is likely it is out of it.

6...Nxe5 7.d4 Re8 

Black sees no reason to retreat a piece from the d-pawn's attack, as White will win one, anyway. So, he develops.

8.dxc5 d5 9.Bg5 dxe4 10.Nc3 Bg4 11.Qe1 Qd4

Black is certainly active and better. The game still has to be won, however.

12.Bxf6 Kxf6 13.Nxe4+ Kf7 14.c3 Qd5 15.Ng5+ Kg8 16.Qc1 Qxc5

Now Black's King is safe, and there is still the matter of the extra piece. What's to worry? Well, for starters, humans can be pretty tricky...

17.h3 Nd3 18.Qc2 Be2

The computer can not see far enough ahead to avoid the Queen sacrifice.

19.Qb3+ Kh8 20.Nf7+ Kg8 21.Nh6+ Kh8 22.Qg8+ Rxg8 23.Nf7 checkmate

Nice.

This is not the first time that LuigiBot has been bested by the Jerome Gambit. See "Poor, Poor Computer" for example.

Jerome Gambit: Smothered

Sometimes the finish to a game is the most sparkling part. Witness the following between Bill Wall and an opponent who will remain anonymous.

For all practial purposes, the game has been over for a while - but Black has been hanging on. Not for much longer, though.

28.Nf7+ Kg8

Now White has the routine discovered check 29.Nd8+, and the game ends either after 29...Kf8 30.Qf7# or 29...Kh8 30.Qe8#.

Why overlook a Queen sacrifice and a smothered mate, however? There is double, discovered check.

29.Nh6+ Kh8

Instead, 29...Kf8 30.Qf7# is again routine.

30.Qg8+ Rxg8 31.Nf7 checkmate

Nice.

Recall the game rigidwithfear - golddog2, Jerome Gambit Tournament, RedHotPawn.com, 2016 for another smother.

It is interesting that The Database has 8 games with the same checkmating pattern, including 2 that ended with an unforced ...Rg8 followed by Nf7#.

Jerome Gambit: First Blood

The Jerome Gambit has drawn first blood in the third round of the Chess.com Giuoco Piano thematic tournament. The game is not very exciting, however, and so games have been added in the notes to compensate.

Black's King usually retreats to the 8th rank.

Ouch. This kind of thing can happen, even in a slow game. Maybe the real world intruded. Maybe White's opening looked too innocuous to worry about in the early stages.

Jerome Gambit: A Few More Early Looks...

After the previous post's glance into the past of this blog, it is hard not to recommend a few more early looks:

"Retro"
"Questions, We Have Questions... And An Occasional Answer"

And, what about coverage of the Jerome Gambit in a fantastic international chess magazine? Ah, there is a saga:

"Delusions of Grandeur" 

Finally:

"The Jerome Gambit Treatment - Unbelieveable!"

Take a break from deep analysis by Stockfish 8 and check out a little related chess history - and more.

Alonzo Wheeler Jerome and Winston Churchill

Ah, yes, years ago I began to explore the possible link between Alonzo Wheeler Jerome, inventor of the Jerome Gambit, and the British statesman, Winston Churchill...

Perhaps it is time to pick up that thread again.

In the meantime, here is an interesting chronology of discovery, with a lot more than just tracing family lines -

Blackburne Shilling Jerome Gambit: Black Runs Out of Energy

In the following game Black is vigorous in his response to White's gambit. However, he seems to run out of energy at the end. Is being down 5 pawns for a piece reason enough to resign? In this case, perhaps not: Stockfish 8 evaluates the final position as even.

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4

4. Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+

8.Qxh8 is a mistake, but I once managed to win with it anyhow, perrypawnpusher - tampajake, FICS, 2009 (1-0, 12).

8...Ke7 9.Qg5+ Nf6

Better than 9...Ke8 in perrypawnpusher - adamzzzz, FICS, 2009 (1-0, 39).

10.Qc5+

Better than 10.e5 in perrypawnpusher - JokeritT, FICS, 2010 (1-0, 28).

10...Kf7

I faced 10...d6 in a number of games; perrypawnpusher - foreverblackman, FICS, 2010 (1-0, 21); perrypawnpusher - vlas, FICS, 2010 (0-1, 23); perrypawnpusher - theferno, FICS, 2010 (1-0, 28); perrypawnpusher - Raankh, FICS, 2010 (1-0, 49); and perrypawnpusher - michon, FICS, 2015 (1-0, 36). Bill, too: Wall,B - Guest5170841, PlayChess.com 2015 (1-0, 15 ).

11.Qxd4 Qe8 12.Nc3 c5 13.Qe3 Qe5 14.h3 Bh6 15.Qf3 Qf4 16.Qe2 d6

Black is fighting back vigorously, despite his slightly exposed King. Still, I am always suspicious of ...c5 in these kinds of positions, as it can allow further opening of the game.

17.d4 Qh4 18.Bxh6 Qxh6 19.dxc5 dxc5 20.e5 Nh5 

Here Stockfish 8 recommends 21.g4!? which is not the kind of move that I can see Bill choosing, as it seems to give even more exposure to his King. Yet the followup is ironic enough for him to appreciate: 21...Nf4 22.Qf3 Kg7 23.0-0-0 (made possible by the Knight's block of the Queen's diagonal) Ne2+ 24.Kb1 Nxc3 25.Qxc3 Be6 with an advantage to White after he captures the c-pawn.

21.Qc4+ Be6 22.Qxc5 Black resigned

Interesting. Compared to Stockfish 8's analysis above, the Knights are still on the board, which would slightly favor White's better piece. However, White's King is not castled, which could be quite risky. 22...Rhd8 would seem to guard well against White's possible Queen check at c7.

In a human vs human game, however, in the long run I would take the extra pawns over the extra piece. It would appear that Black agreed.
