A Jerome Gambit Database

Scouring the internet with Google the other day, I ran across A Jerome Gambit Database set up by an anonymous creator who appears to have knowledge of Bill Wall's games, Rev. Tim Sawyer's blog, and this site as well. Feel free to check it out. If you have any more information about the site or author, please let me know.

This Is Your Last Chance

After the previous post on the Jerome Gambit Declined, here is a fun example (or three: also see my two games against walkinthespirit: #1 and #2).

blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.Bxf7+ Kf8 6.Bb3

Transposing to the main Declined line, 4.Bxf7+ Kf8 5.Bb3 Nf6 6.0-0. Black, given one, only, and his last chance to accept one or two pieces, shows that he wants no part of White's goofy attack - and strikes back

6...d5 7.exd5 Nxd5 8.Nxe5

White responds with the "fork trick".

8...Nxe5 9.d4 Be7 10.dxe5 Nb4

It is too late to quibble that 10...c6 was stronger.

11.Qf3+ Ke8 12.Qf7+ Kd7 13.Rd1+ Black resigned

All or Nothing! notebook (1)

Working on my book, All or Nothing!, The Jerome Gambit, has forced me to take a better look at variations that I have generally dismissed.

The first line to get more attention is one that I have thought little about, the Jerome Gambit Declined.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8 

In the broader sense of things, it seems odd that Black would give up an "objectively" won game (White has sacrficed one piece and may sacrifice a second) to be down material, all at move 4.

In fact, the line is rarely played: of 10,670 games in The Database that have White's first four moves, above, only 245 - roughly 2% - contain 4...Kf8. Less than 1/2 % contain 4...Ke7.

Yet, Black may have his reasons, if only based in psychology. For starters, he does not give White the wild play he is looking for - in fact, Black becomes the gambiteer, offering a pawn and position for slightly better development. White must take further risks if he want's to challenge that situation.

White's best move in response to Black declining the Bishop is to play 5.Bb3 (or the similarly-motivated 5.Bc4 or 5.Bd5) settling for a solid pawn plus and eventual play against Black's displaced King. Also good for White is 5.Bxg8, exchanging rather than retreating the Bishop.

It is quite possible that Black declines the Jerome Gambit in hopes that White will continue to offer the piece with 5.Nxe5!? or 5.0-0!? with the plan to transpose into the Jerome Gambit accepted, where Black eventually takes the Bishop, having taken two moves to do so, instead of the usual one. This is convoluted thinking, that White, having been spared a losing game, will want to persist in seeking his attack/disadvantage, rather than settle for an advantageous non-Jerome Gambit position...

The Jerome Gambit: it has its own logic!

Not What Was Expected

In the following game Bill Wall played the Jerome Gambit, retreated his Queen to an odd square, allowed it to be exchanged off - and, later won. All in all, not what was expected for a "refuted" opening, played loosely - but what did you expect? Bill goes on to win in the endgame.

Wall,B - Guest10254637
PlayChess.com, 2014

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

7.Qxe5 d6 8.Qc3

A more usual retreat is 8.Qg3, but Bill likes to experiment. 

8...Qf6 9.0-0 

A small caution: 9.Qb3? Qxf2+ White resigned, GeniusPawn - satori, FICS, 2000. 

9...Qxc3 

Also seen was 9...Bd4 10.Qxc7 Bxb2 11.Bxb2 Qxb2 12.Qxd6+ Ne7 13.Nc3 Kf7 14.Qf4+ Ke8 15.Nd5 Nxd5 16.exd5 Kd8 17.Rfe1 Qxc2 18.Qg5+ Kc7 19.Rac1 Qxc1 20.Rxc1+ Kb8 21.Qe5 checkmate, guest714 - guest1041, Internet Chess Club, 2003.

10.Nxc3 

White has two pawns for his sacrificed piece.

10...Nf6 11.d3 Kf7

Black did not castle-by-hand in Abijud - djinmaster, FICS, 2005:  11...Bg4 12.a4 a6 13.Bg5 h6 14.Bxf6 gxf6 15.Nd5 Bd4 16.c3 Be5 17.f4 Be2 18.fxe5 Bxf1 19.Rxf1 dxe5 20.Nxf6 Ke7 21.Nd5+ Kd7 22.Rf5 c6 23.Nb6+ Ke6 24.Nxa8 Rxa8 25.Rh5 Rh8 26.Kf2 Rh7 27.Ke3 Kf6 28.g4 b6 29.h4 c5 30.Rf5+ Ke6 31.g5 hxg5 32.hxg5 Rh3+ 33.Kd2 Rh2+ 34.Kc1 Black forfeited on time. 

12.Re1

Bill points out two alternatives: 12.Na4 Bb4 13.a3 Ba5; and
12.Be3 Bxe3 13.fxe3 c6. 

12...Rf8 13.h3 Bd7 14.a4 Rae8 15.Be3 Bb4

I suspect that Black felt good about this move, taking advantage of the fact that the Bishop cannot be kicked away by a2-a3. The fact is, though, that White can now spring his "Jerome pawns".

16.f4 a6 17.Re2 Bc6 18.Rf2 Bxc3 19.bxc3

Black will now give back his piece to fracture White's pawns.

19...Bxe4 20.dxe4 Nxe4

The rest of the game is interesting, as White's pawns are not as weak as they appear - or the pawn structure gives chances to White's pieces. The game is balanced - for a while.  

21.Rf3 Nxc3 22.Bf2 Ne4 23.Bd4 d5 

24.Rb3 b6 25.Rd1 Kg8 

Completing castling-by-hand, but perhaps that was no longer necessary, in which case it is not a good use of tempo. 

26.Be5 Nc5 27.Rc3 c6

Bill points out the better 27...Rd8 28.Bxc7 Nxa4. 

28.a5 Nd7 29.axb6 Nxb6 30.Rxc6 Nc4 31.Rxd5 Ne3

Black misses his chance to exchange off White's Bishop and head toward  a R + Ps endgame where he has practical drawing chances, Bill notes: 31...Nxe5 32.fxe5 Rf5 33.Rxa6 Rfxe5 34.Rxe5 Rxe5.

32.Rd7 Rf7 33.Rxf7 Kxf7 34.Kf2 Nd1+ 35.Ke2 Nb2 36.Kf3 Na4 37.Rxa6 Nc5 38.Ra7+ Black resigned

Happy New Year!

Wishing Readers an exciting, healthy and hopeful 2015!

Alert! Alert!

In my last post I mentioned that I have a Google "alert" set for "Jerome Gambit". I griped that it rarely returned anything, and when it did, it mostly gave a link to one of the posts on this blog (not always a current one).

However, once again it linked me to a game at lichess.org. The contest is a one-minute, "bullet" game featuring the Jerome Gambit!

dwcgc at lichess.org is a player from the Netherlands with a taste for unorthodox chess openings - played very quickly (in the following game, slightly slower than a second a move). Take a look.

I also found a recent game with dwcgc playing the Busch-Gass Gambit (see "Worth a Second Look... "Part 1, Part 2 and Part 3), a sort-of "reversed Jerome Gambit."

Alert!

I have a Google "alert" set for "Jerome Gambit". It rarely returns anything, and when it does, it mostly gives me a link to one of the posts on this blog - not always a current one.

The other day, however, it linked me to the following game at lichess.org. The game is given there as an example of "Bishop's Opening, Jerome Gambit," which is a bit of a misnomer, in that Alonzo Wheeler Jerome did not play or analyze the line (as far as I have been able to discover in 13 years of research into the Jerome Gambit).

I have called the line the "Abrahams Jerome Gambit" (see Part 1 and Part 2 among several references), after the British chess player and author Gerald Abrahams (1907 - 1980) who referred to it as the Jerome Gambit in at least two of his books.

In the following game, White is not able to develop an attack worthy of the piece sacrificed, and eventually loses on time in an undermanned endgame.
