Repairing a Variation (Part 4)


Once you have defined the problem (Part 1) with an opening variation, reviewed some game history (Part 2), and seen what has been written about the line (Part 3), it is time to analyze and test out new ideas.

In the case of the "Nibs" defense of the Jerome Gambit, (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) there are three strategies to choose from.


#1) Embrace the chaos

You may choose to continue to play the main line, anyway, believing that it is so complicated that your opponent will never find a way through to the advantage. (So far, only one player, peonconorejas has.) In this case, it is important to be familiar with the places (especially moves 10 through 17) where Black might slip up, so that your greater understanding of the strategic and tactical nuances gives you the better chances.

An example is perrypawnpusher - electrahan, blitz FICS, 2009.


Black did not discover the killer 10...Ne7 (and the idea behind it) and instead retreated his Queen with 10...Qh6.

Three moves later I reached the following position.

My comment at this point of the game was

My one advantage against electrahan was that I was more familiar with the positions and play, and so was significantly ahead on the clock.

The game continued to be very interesting, and I prevailed in 35 moves.




#2) Find a Jerome Gambit endgame that you are comfortable with.

Much to my annoyance, despite a lot of hard work (with the help of Rybka 3, Fritz 8 and ChessBase 8) I have not yet found a "bust" to Black's Queen sacrifice in the "His Nibs" defense.

Players who are comfortable with a Jerome Gambit endgame (blackburne and mrjoker come quickly to mind) – with one, two or three pawns for the sacrificed piece; ideally, also with an active King – can look at the following line.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+ 9.g3 Nf3+ 10.Kf1

If you are going to battle the Queen-sac line, I think 10.Kd1 is the right move. If you are looking toward the endgame, 10.Kf1 is to be preferred.

10...Ne7 The same strong move with the same strong threats. 11.Qxc5+ This move will either displease or please your opponent, depending on whether the second player knows the Queen-sac line or not. 11...Kxc5 12.gxh4

This is an interesting position. White has two pawns for a piece, although the one at h4 is threatened. As long as a lot of pieces remain on the board, Black's King is at risk; but with each exchange, he becomes more of an attacker than a defender. Black's advanced Knight may or may not be in danger, similar to the game perrypawnpusher - Temmo, Chessworld, 2008.

It's not very exciting for White after 12...Nxh4 13.Nc3 (with d2-d3 and possibly Rh1-g1 to follow) but if Black's Knight becomes dim on the rim, or if White's King can mosey over that way, there may be some play to be had.

#3) Change to another line of play.

In this case, it might be worth investigating 7.f4, instead of the 7.Qf5+ and 8.f4 line, something that I am doing right now.

(But I still hope to be able to crack the Queen-sac some day!)
