Waiting for the Blunder Bomb

One theory of chess play is that each person has a set of imaginary "blunder bombs" inside of himself or herself that explode rarely if the player is very strong, but explode frequently, if the player is not so strong. Under this model, a stronger player can expect to win if he or she plays simple, safe moves, waiting for the weaker player's "blunder bomb" to go off first. Of course, if the stronger player introduces an unusual and tricky opening such as the Jerome Gambit, the opponent's bomb might go off even sooner...

Play the Jerome Gambit Quad

Around the corner, as it were, to the "1st Jerome Gambit Race" at Chess.com, mentioned in yesterday's post, is Chess.com's Play the Jerome Gambit Quad, which includes long-time Jerome Gambit Gemeinde member Bill Wall.

I'd like to share some of the rock 'em sock 'em games, starting with the first one finished.

There are only 8 examples of this gambling move (Will Black withdraw his Knight? Will he capture the pawn on f4?) in The Database, with the oldest being from a game between Hiarcs8 and Fritz7 in 2002 (0-1, 59), and the most recent from a game between Yigor and mrdenetop (1-0, 10) from the Kentucky Opening /Jerome Gambit tournament played at Chess.com last year (see "My Old Kentucky... Opening" and "Sunday Tournament Update").

8...g6 9.Qh3+ Kf7 10.Nd5 Qc6


Allowing White to capture at e5, which opens the floodgates.

Black is in trouble, but this move leads to mate.

1st Jerome Gambit Race

I noticed that Chess.com recently held its 1st Jerome Gambit Race. The players, how they finished, and their scores 


#1 calcot (1448)                      4-2-0
#2 Merlin-Pendragon (1393)    3-3-0
#3 Jordi-I (1430)                     3-3-0
#4 couchpotatoe (1345)           2-4-0

Sadly, there was only one win by White (against what could have become a Blackburne or Whistler Defense).

In addition, in the following games White had commanding advantages until move 17 (first game) and move 24 (second game)

I'll take care of it later...


It is time to take a break from "Return of Jerome Gambit for Dummies" to take a look at a recent blitz game from FICS. Black seems to be settling into his chair, becoming comfortable with his position (after all, it's only the Jerome Gambit), when things "suddenly" go wrong.

perrypawnpusher - Odeon
blitz, FICS, 2012


1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.0-0 Bc5


 6.Bxf7+

The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 Re8

10.f4 Nc6

I have had a habit of playing 11.Qd3 (most recently perrypawnpusher - kholthaus, blitz, FICS, 2011) in this and in similar positions, naively hoping for ...Nb4, which would drop the Knight to Qc4+.

My choice in this game was based on the idea that Black would be less likely to make that slip than to choose the move that he actually does make.

11.Qc4+ Kf8

This move is not an error (although 11...d5 is a bit stronger) but it does allow White to get a tighter grip on the center.

12.e5 Ng4

This looks like a "That's okay, I'll take care of it later" kind of play, in that Black sees no problem with moving his piece to a more aggressive position.  Retreating to g8 or h7 was the prudent choice.

13.h3 Ngxe5

Played relatively quickly, as if "Hey, no problem, I'll return the piece for two pawns and active play." White would have an edge after 13...d6 14.hxg4 Bxg4

14.fxe5+

The check makes a big difference.

14...Ke7 15.Qf7 checkmate

Um... Well... Er...

Following the theme of "short Jerome Gambit games" that has run through the recent "Return of Jerome Gambit for Dummies" series of postings, I recently found three chess games from a 2010 tournament at the online site Little Golem (where you can play many different board games). I'm not sure what to make of the games, however...

The Return of Jerome Gambit for Dummies (Part 5)


Continuing my search for the "essence" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), or at least an insight into how it "works", I discovered that 7-move wins by Black were not so much improvements in defense (after all, after accepting two sacrificed pieces Black needs merely to "hold on") as they were instances of White throwing away a Knight (see "The Return of Jerome Gambit for Dummies Part 2") , a Queen, or a King. Some examples of the last case are given as a warning for White to "pay attention".

The Return of Jerome Gambit for Dummies (Part 4)

As I continued looking for the "essence" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), or at least an insight into how it "works", I discovered that some of the 7-move games in The Database began to "predict" some of the regular main lines.

For example, in the following three games White's recovery of one of the pieces that he had sacrificed is enough for Black to surrender, even though the second player actually remained with the advantage.

Some of the other short games began to highlight the attacking ideas open to White in the Jerome Gambit, if the defense faltered.
