I am used to playing over 1-minute (no increment) Jerome Gambit games by angelcamina. Occasionally I have wondered, what would happen if he had more time to work his magic?
Recently I found out - he sent me a 5-minute game that got weird, fast, and that's saying something for a Jerome Gambit.
For some enlightenment, I did what I usually do: turning to The Database I looked at some of the games with that line that had been played previously. There were only 5, I'm not sure how many of those games had a grip on the line, either.
So, I turned to my trusted Komodo 10 for insight - you can probably guess how that turned out.
Finally, I reviewed my blog, and, although I had peeked at the line, before - see "Boris isn't so hot..." and ''Jerome Gambit Hammer" - there was still more to be said.
Here's how it all came down...
angelcamina - nanangtisna
5 0 blitz, lichess.org, 2020
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 g5
Here's a position you don't see very often. What is it all about? What is Black getting at?
It is possible to get a hint by looking at a Bill Wall game that continued 8.fxe5 Qf8, as if Black were offering a counter-gambit followed by a threatened Queen check at f2. Bill wasn't impressed, however, and quickly found a solution after 9.Rf1 Qe7 10.Qg4+ Kxe5 11.Qf5+, Black resigned, facing a mate in 1, Wall,B - Lisandru, Chess.com, 2012. The defender's Queen should have gone to g7 instead of e7, but 10.d4 would have then cemented White's avantage.
8.fxe5 Kxe5
After a long think (26 ply), Komodo 10 passes up this move, as well as 8...d5 and 8...Ne7, and chooses Stockfish 7's suggestion from 4 years ago, 8...Nf6 9.exf6 Qxf6 10.Rf1 Qg6 11.Qe2 Ke7, with White up about a pawn and a half.
But nanangtisna's choice of move is reasonable.
9.Qf7
Setting up a mating net.
Previously, 9.Rf1 was seen in GuestCRJQ - Despistado, FICS, 2009 (1-0, 26), Wall,B - Boris, sparkchess.com, 2012 (1-0, 16) and Vlastous - PornobeshKumar , internet, 2016 (1-0, 13).
Also successful was 9.c3 Be7 10.d4+ in Black,D - Boris, sparkchess.com, 2012 (1-0, 18).
Probably best is Komodo 10's (and Stockfish 7's!) 9.d4+, as 9...Bxd4 10.Bxg5 Nf6 11.Bxf6+ Kxf6 12.Rf1+ Kg7 13.Rf7+ Kg8 14.Rf3 Bf6 15.Nc3 Kg7 remains, as I noted
a line worth looking at in detail as an example of building an attack.9...d5
Often this strike at the center, opening up lines for development, serves Black well in the Jerome Gambit. Here, though, 9...Nf6 might have been better, although White could meet it with 10.d4+, with play similar to that in Vlastous - PornobeshKumar, Internet, 2016.
It is worth pointing out, again, that this is a 5-minute blitz game, and it is always easier to come up with improvements after the fact.
10.Qg7+
Out of the blue, Komodo 10 prefers 10.b4. It takes a moment to realize that it has not just found a way for White to castle - 10...Bxb4 11.0-0 - as it further recommends that Black answer with 10...Nf6, giving up a piece to 11.bxc5. No, the b-pawn advances to allow White to subsequently fianchetto his dark squared Bishop.
The idea 10.b4 Bd4 11.c3 Bb6 12.d4 reminds me of a suggestion that Stefan Bücker made to me in a similar line, back in 2004, when I still hoped to have my Jerome Gambit article published in his fantastic chess magazine, Kaissiber. See, fittingly, "Delusions of Grandeur".
