Traps and Zaps
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6
Druke gave this move as an alternative to Fletcher's 9...Qxe4+ 10.Be3, saying that it came from analysis by Fritz 5. Of course, the two lines can transpose; in either case, as Hindemburg Melao, Jr., wrote in an intenet article (2003) on Amateur - Blackburne, London 1885 (not currently available), White's proper response is Nd2.
Scenario: Don't be misled by White's extra Rook. It's a meaningless ornament. White is in serious trouble. His King is exposed and his cornered Queen is in danger of being trapped. The cruncher is 12...Bh3 which wins White's Queen by discovery form the a8-Rook. If White tries to save the Queen by capturing the Rook, 13.Qxa8 then 13...Qxf1+ 14.Kd2 Ne4 is mate.
Interpretation: White began with a very aggressive, sacrificial line of play which, because of Black's cavalier pawn move (6...g6), led to the gain of material. The price White had to pay was the removal of his Queen from the center of the board. Without his Queen being available for defense, White has to play carefully, and every move becomes critical. Instead of his h1-Rook, he should be more concerned with the potential trap of his Queen. The correct response to 11...Qxg2 is 12.Nc3 which later prevents Black's Knight from moving to e4 and giving mate. After 12...Qxh1+ 13.Kd2 Qxa1?(13...Qxh2 keeps Black's Queen in play), White turns the tables with 14.Bd4!. Black's extra Rook then means little in the face of White's strong counterattack.

The extraordinary and forgotten Jerome Gambit
I always enjoy John Elburg's book reviews.
Of course, who wouldn't enjoy his look at International Master Gary Lane's latest title, The Greatest Ever Chess Tricks and Traps ? --
Gary Lane provides the reader in this greatest ever chess tricks and traps book with a amazing collection short cuts.
Some are well known as the seven move lost from the poor Ree against Petrosian,at the Wijk aan Zee tournament from 1971, but many others as for example the game Banks – Karmmark, Internet Blitz 2007, are brand new.
Where white went for the extraordinary and forgotten Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+?
These moves, as we can read in this entertaining work from Lane is named after the American player Alonzo Wheeler Jerome 1834-1902 of Paxton, Illinois, and was analysed in the American Chess Journal in 1874. It has to be remembered that in the 19th century people liked to attack and never defend.
This book from Lane is not only a very exciting game collection but above all, a very good read.
Nearly all major openings are divided with a instructive example of play and all games in this book are pleasantly indexed with names and openings.
All together I counted around 110 complete games where some are good for over two pages of text!
As for example the following victory in the opening: Skurski, Jan (2069) - Gasik, Piotr (2189) [B12] POL-ch sf Polanczyk (6), 09.11.2000 1.e4 c6 2.d4 d5 3.f3 dxe4 4.fxe4 e5 5.Nf3 exd4 6.Bc4 Bb4+ 7.c3 dxc3 8.Bxf7+ Kxf7 9.Qxd8 cxb2+ 10.Ke2 bxa1Q 11.Ng5+ Kg6 12.Qe8+ Kh6 13.Ne6+ g5 14.Bxg5# 1-0
As we can read in the book from Lane black has tried to avoid defeat at this point with no success.
Conclusion: This book is overloaded with unbelievable shortcuts!

Be careful what you wish for...
Sometimes, though, it seems that this broader knowledge of the Jerome Gambit (and its relatives) has a chance to come back and haunt me (see, for example, "Where are all of these Jeromes coming from?").
Today, for example, I was minding my own business, looking for a 3 0 blitz game on FICS – admittedly, way too fast a time control for an addled mind like my own – when suddenly familiarity struck!
leobrazer - perrypawnpusher
blitz 3 0, FICS, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6
The good old Two Knights Defense.
4.Bxf7+
Ha! says my opponent (in my imagination, anyhow).
Oh, bother! say I (to myself). In a three-minute game, of all things...
4...Kxf7 5.0-0 Bc5
Transposing to a "modern" Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6.
6.Nc3 Rf8 7.Ng5+
Trickier and stronger was the thematic 7.Nxe5+, when 7...Nxe5 8.d4 Bd6 9.f4 Nc6 10.e5 Kg8 11.exd6 cxd6 12.Be3 is okay for Black, although I would have probably chosen 7...Kg8 instead.
7...Kg8 8.d3 d5 9.exd5 Nxd5 10.Nxd5 Qxd5
Move quickly, avoid a blunder, I have an extra piece...
11.Bd2 Bf5 12.c4 Qd7 13.Bc3 Qxd3 14.Qxd3 Bxd3
Faster, faster, a piece up in the endgame still wins...
15.Rfe1 Bxc4
Too fast: missing 15...Bxf2+
16.b3 Bf7
Ditto.
17.Nf3 Rae8 18.Nxe5 Nxe5 19.Bxe5 Bd6
Better 19...Bxb3. The clock is ticking down, but I have more time than my opponent, who now slips...
20.Re4 Rxe5 21.Rxe5 Bxe5
Home free: just have to play Beat The Clock...
22.Re1 Re8 23.g3 Bd4 24.Rxe8+ Bxe8 25.Kg2 Bg6 26.Kf3 Bb1
We were banging out moves here.
27.Ke2 Bxa2 28.Kd3 Bf6 29.b4 Kf7 30.f4 Ke6 31.Ke4 Be7 32.f5+ Kf6 33.g4 Bxb4 34.h3 a5
There's enough time left for this to decide the game.
35.Kd4 a4 36.h4 h6 37.g5+ hxg5 38.hxg5+ Kxf5 39.Ke3 a3 40.Ke2 Bb3 41.Ke3 a2 42.g6 a1Q 43.Kf3 Qf1+ 44.Ke3 Bc5+ 45.Kd2 Qf3 46.Kc1 Qf2 47.Kb1 Qc2+ 48.Ka1 Qa2 checkmate
Whew!

It's a good thing I read this blog
perrypawnpusher - adamzzzz
blitz 10 0, FICS 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4
Tsk, tsk, tsk. Time to Jerome-ize.
4.Bxf7+
This caught my opponent by surprise. I could tell by his long think.
4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+
Discussed and recommended on the jeromegambit.blogspot.com blog.
8...Ke7 9.Qg5+ Ke8 10.Qe5+ Qe7 11.Qxd4
White has 4 pawns for his piece, and Black has yet to get over his sense of surprise.
11...Bg7 12.Qc4 Kd8 13.Nc3 Nf6 14.O-O c6 15.d4 d5
Of course, this move would be stronger with the Queen on d8.
16.exd5 Nxd5 17.Nxd5 cxd5 18.Qxd5+ Qd7 19.Bg5+ Kc7 20.Qc5+ Qc6 21.Qxc6+ bxc6 22.c3 Rb8
A blitz slip, although it takes me a lucky moment to notice it.
23.b3 Rh5 24.Bf4+ Kb7 25.Bxb8 Kxb8 26.Rae1 Ba6 27.Re8+ Kc7 28.Rfe1 Bh6 29.R8e5 Rxe5 30.Rxe5
30...dxe5 was probably more consistent.
The rest of the game features two unencumbered Bishops against a Rook and a lot of targets, er, pawns. Fortune favored the Jerome...
30...Bd2 31.c4 Bc3 32.Re4 Bb7 33.d5 cxd5 34.cxd5 Bxd5 35.Re7+ Kb6 36.h4 Bf6 37.Rd7 Be6 38.Rd6+ Kc7 39.Rxe6 Black resigns

Jerome Gambit for Dummies (3)
The difficulty in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) after 4...Kxf7 5.Nxe5+ Nxe5 6.d4 can be illustrated by the following diagram, after Black's best move, 6...Qh4:
White will most likely get one piece back, but it's sobering to realize that he sacrificed two pieces to get to this position...
On the other hand, if the first player opts for 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Black has many "refutations" at his disposal, but need only remember one: 6...g6 7.Qxe5 Qe7 - Whistler's Defense - to have a winning game.
So - What's a Jerome Gambit Gemeinde to do?? (Stay tuned.)

Jerome Gambit for Dummies (2)
This is the first Critical Position in the Jerome Gambit. Although 99% of the time (according to my database) Black captures the Bishop, the move is not forced. It is simply a choice for the second player between having an objectively winning game (4...Kxf7) and having the worse position (after 4...Kf8/4...Ke7 5.Bb3). Yet a few defenders will adopt the sly attitude If he wants me to take the Bishop, then I won't take it. There is some "psychology" in this, too: the Jerome Gambiteer suddenly finds himself or herself "stuck" with a calm, but immesurably "better" game than had been expected a move before. This change of fortune can take some getting used to. Those who resist may wish to resort to 5.Bxg8 or 5.Qe2 (if 5...Kxf7 6.Qc4+); or transpose to the Evans Jerome Gambit with 5.b4.
4...Kxf7 This is the second Critical Position. The "classical" Jerome Gambit continues with 5.Nxe5 (about 84% of the games in my database) while "modern" Jerome Gambits continue with alternatives such as 5.Nc3, 5.d3, or 5.0-0. For the record, after a very long think (over 12 hours) Deep Rybka 3.0 Aquarium assesses Black as being 1.91 pawns better after 5.Nxe5+ as well as after 5.Nc3. It sees White being only 1.72 pawns worse after 5.d3 or 5.0-0.
One fifth of a pawn doesn't seem like a lot to me, and I still prefer the complications of 5.Nxe5+. Jerome Gambiteers who feel they can knuckle down and simply outplay their opponents with the "modern" variations are free to disagree with me.5.Nxe5+
This is the third Critical Position. Black's most frequent response is the logical 5...Nxe5, but he has alternatives in 5...Kf8, 5...Ke8 and 5...Ke7. The first of these "others" is a respected defense going back to Jerome - Brownson, Iowa 1875 (1/2-1/2, 29). The other two are blunders that give White the advantage after 6.Qh5.
After 5.Nxe5+ Kf8, the Banks Variation (see "Jerome Gambit and Vlad Tepes..." and "Jerome Gambit, Vlad Tepes... and Garlic!") is tempting, but probably Alonzo Wheeler Jerome's 6.Nxc6 is best.
5...Nxe5 This is the fourth Critical Position. White most frequently follows up with 6.Qh5+, although 6.d4 is also played, and there are a number of rare other moves.
