Further Updating the Semi-Italian Jerome Gambit


Today we return to a rare line in the Semi-Italian Jerome Gambit, on behalf of HauntedKnight of FICS, who has over 230 Jerome Gambit and Jerome-related games in The Database.

The Semi-Italian Opening.

4. O-O Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit.

5...Kxf7 6. Nxe5+ Nxe5 7. d4 Qh4


Mentioned previously in "Updating the Semi-Italian Jerome Gambit". The move is reminiscent of what I have called a "Pie-in-the-Face Variation" in the regular Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5+ 6.d4 Qh4!?

The question here, in the Semi-Italian Jerome Gambit, is, how much does giving White a useful move (0-0) and having Black waste a move (...h6), change what is a clear plan of refutation in the Jerome Gambit proper.

8.dxe5

For starters, White gets to capture one of Black's pieces in this variation. In the regular Jerome Gambit line, of course, capturing the Knight with 7.dxe5 would lead to 7...Qxf2#. (There is actually one such game in The Database.) Capturing the Bishop with 7.dxc5 in the regular line would lead to 7...Qxe4+ (best) and White was lucky to score 28% out of 52 games in the Database.

In the current game, White's King is castled, and thus safer. Still, he should have captured the other Black piece with 8.dxc5, leading to an almost-balanced game.

Instead, this move and his following move turn Black's Bishop into a monster. In unexplored territories - remember, this is the only 7.d4 Qh4 Semi-Italian Jerome Gambit game in The Database - there are often monsters.

8...d6 9.exd6

White had to try to hang on with 9.Nc3. 

9...Bxd6 

White now fights valiantly, but to no avail.

10.f4 Nf6 11.e5 Ng4 12.h3 Bc5+ 13.Kh1 Nf2+ 14.Rxf2 Qxf2 15.Qh5+ g6 16.Qd1 

White can only annoy the Black King, and then fall back on defense.

16...Bf5 17.Qd5+ Be6 18.Qd1 Rad8 19.Nd2 Bd5 20.Qf1 Qxf1+

Black is content to simplify; perhaps it was a question of time on the clock. With 20...Qg3 he would have a checkmate in 7 moves. 

21.Nxf1 Kg7 22.Be3 Bxe3 23.Nxe3 Bc6 24.Kh2 Rhf8 25.g3 g5 26.Nf5+ Rxf5 White resigned



Despite the outcome of this game, White should not fear 7...Qh4, but go ahead and capture the Bishop with 8.dxc5, followed by development of his pieces and then the advance of his "Jerome pawns".

Updating the Semi-Italian Jerome Gambit


I have had a long-term interest in the Semi-Italian Jerome Gambit, so-called because it can arise from the move order - among others - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 h6. (For example, see "A Jerome Look At The Semi-Italian Opening" Parts 1, 2, and 3).

More than a third (37%, actually) of the games in The Database with this move order were played by me, and I've scored 89% with the line.

I thought it was a good time to take another look at some recent games and update my knowledge.

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 



I was surprised to see that Houdini 3 prefers this move to my choice, 7.Qh5+. I have played 7.d4 in only 3 of my 54 Semi-Italian Jerome Gambit games. Shows what I know.

7...Bxd4 

I wondered how often Black played 7...Qh4!? in this position, similar to 6...Qh4!? in the main line Jerome Gambit with 6.d4 (instead of 6.Qh5). It turns out that there is only one game example in The Database, HauntedKnight - keeper, blitz, FICS, 2012 (0-1, 26). This line deserves further exploration.

8.Qxd4 d6

There are 9 examples of ndrwgn playing this position in The Database, and he has scored 56%.

9.f4 c5 

"Meeting A Threat With A Threat", but 9...Nc6 was a more stable alternative. The text causes immediate difficulties.
