Evans-ish Abrahams Jerome Gambit

In the previous post (see "Jerome Gambit: Move That Knight!") I shared a couple of outrageous ways (other than sacrificing it at e5) for White to move his King's Knight out of the way in the Jerome Gambit so that his Queen can enter the fray.

Of course, one "solution" is not to put the Knight there in the first place. Consider the Abrahams Jerome Gambit, 1.e4 e5 2.Bc4 Bc5 3.Bxf7+!?

I consulted The Database, and learned that it has one 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ game by Bill Wall - always a good openings experimenter to check out - played on the internet in 2001. (Even that far back, he played a couple of games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.)

It turns out that at the same time Bill was extending his experiments a bit, as the following game shows.

Wall, Bill - Quianna
Internet, 2001

1.e4 e5 2.Bc4 Bc5 3.b4

This move is at least as old as the MacDonnell - La Bourdonnais, London match,1834.

3...Bxb4 4.c3 Bc5 5.d4 exd4 6.Bxf7+



Here we have what might be called the "Evans-ish Abrahams Jerome Gambit", as it is not quite an Evans Gambit without Nf3/Nc6. The game follows MacDonnell - Boden, London, 1869, for 5 moves, but the first game example that I have of the move 6 Bishop sacrifice is from 2000. (Light analysis of the sacrifice is at least as old as Jaenisch's Analyse Nouvelle des ouvertures in the 1840s.)

6...Kxf7 7.Qh5+ g6 8.Qxc5



NM Eric Schiller, in notes to a game (Denker - Shayne, Rochester, New York, 1945) at Chessgames.com, said this position "looks very good for White". (It's probably about even - but for White to reach equality in 8 moves in any kind of Jerome Gambit has got to be very good, right?)

8...dxc3

The kind of pawn-grabbing that is usually punished.

Instead, Stockfish 9 suggests 8...Qe7 - as seen in Delanoy - Kamenecki, Cannes, France, 2000 (1-0, 38) - with an even game. However, Michael Goeller, a Bishop's Opening expert, gives that move a "?!" and prefers 8...Nf6 - no games in The Database - which he gives a "!", with an even game. There doesn't seem to be anything wrong with 8...Nc6 or 8...d6, either.

9.Nxc3 d6 

10.Qd5+

Psychological warfare. Bill has used a similar Queen check in the Jerome Gambit proper to question Black: Do you want to play ...Be6 and give up the b-pawn? 

10...Kf8

Black replies Not quite, and keeps his King off of the a1-h8 diagonal, where one of his Rooks lives, and where White's remaining Bishop might take up residence. Yet, 10...Kg7 might have been a better move.

11.Nf3 c6

Kicking the Queen, instead of focusing on development.

White has ample compensation for his sacrificed pawn (development, Black's unsafe King), and his opponent's next move, a nervous oversight, ends the game.

12.Qd4 c5 13.Qxh8 Black resigned
