After this game was finished, I checked with The Database, and discovered that my opponent and I had "discussed" this opening (over the board) several times previously.
In addition, before I post a game on this blog, I usually "discuss" it with either Houdini 3 or Stockfish 6, hoping for enlightenment.
This time, however, my two electronic "friends" did not always agree in the early stages, occasionally sounding like a couple of know-it-all kibitzers, leaving a current assessment of the opening lines a bit unsettled.
Ironically, the game was tipped by the endgame play of both me and my opponent - as HAL 9000 once said, "It can only be attributable to human error."
perrypawnpusher - michon
blitz, FICS, 2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+
The Blackburne Shilling Jerome Gambit.
4...Kxf7
My opponent declined the piece a couple of times, a couple of years ago, with 4...Ke7, but without success: perrypawnpusher - michon, blitz, FICS, 2013 (1-0, 8) and perrypawnpusher - michon, blitz, FICS, 2013 (1-0, 41).
5.Nxe5+ Ke8
Instead, 5...Ke6 was seen in perrypawnpusher - michon, blitz, FICS, 2014 (1-0, 23); while 5...Ke7 was seen in perrypawnpusher - michon, blitz, FICS, 2013 (1-0,18).
6.Qh5+
This move was preferred by Houdini 3 after some deep thought.
Some human input: In over 70% of the over-2,100 relevant Blackburne Shilling Jerome Gambit games in The Database, White chose 6.Qh5+, scoring 60%.
Instead, Stockfish 6 preferred 6.c3.
Again: In 21% of the relevant Blackburne Shilling Jerome Gambit games in The Database, 6.c3, was the people's choice, scoring 55%.
I checked, and noticed that 6.c3 was first mentioned on this blog in "Blackburne Shilling Jerome Gambit", 7 years ago.
Interestingly, an earlier version of Stockfish expressed a preference for 6.c3 about 5 years ago.
The choice of 6.Qa5+ or 6.c3 still seens to be an "Unfinished Discussion" (posted 3 years ago), although it seems that 6.c3 may have appeared in more blog posts than 6.Qh5+.
Here are a couple of examples of the 6.c3 Nc6 7.Nxc6 dxc6 8.d4 Qh4 line suggested by Stockfish 6: 9.0-0 (9.g3 Qxe4+ 10.Qe2 Qxe2+ 11.Kxe2 Bg4+ 12.f3 Bf5 13.Re1 Bxb1 14.Kf1+ Be7 15.Rxb1 Kd7 16.Re2 Re8 17.Be3 Nf6 18.c4 Rhf8 19.b4 Ng4 20.Kg2 Nxe3+ 21.Rxe3 Bxb4 22.Rxe8 Rxe8 23.Rxb4 Re2+ 24.Kh3 Rxa2 25.Rxb7 Ra4 26.Kg4 Rxc4 27.Rxa7 Rxd4+ 28.f4 c5 29.Ra8 c4 30.Rh8 c3 31.Rxh7 c2 32.Rxg7+ Kc6 33.Rg6+ Rd6 34.f5 c1Q 35.Rxd6+ cxd6 36.f6 Qc4+ 37.Kf5 Qf1+ 38.Ke6 Qh3+ 39.Ke7 Qd7+ 40.Kf8 d5 41.f7 d4 42.Kg8 Qg4+ 43.Kh8 Qh5+ 44.Kg8 Qg6+ 45.Kf8 d3 46.Ke7 Qxf7+ 47.Kxf7 d2 48.h4 d1Q 49.h5 Qxh5+ White resigned, marinrouge - homerg, FICS, 2002) 9...Ke7 10.Nd2 Nh6 11.Nf3 Qh5 12.Qd3 Kd8 13.Bg5+ Be7 14.Bxh6 gxh6 15.Ne5 Bd6 16.Qg3 Be6 17.f4 Bxe5 18.fxe5 Rg8 19.Qf3 Bg4 20.Qf7 Qxf7 21.Rxf7 Kc8 22.Kh1 b6 23.Raf1 Kb7 24.Rxh7 h5 25.Rff7 Rac8 26.d5 cxd5 27.exd5 Be2 28.d6 Rgf8 29.Rxc7+ Rxc7 30.Rxc7+ Ka6 31.h3 h4 32.Kh2 Bb5 33.Rg7 Bc6 34.e6 b5 35.d7 Rf6 36.Re7 Bd5 37.d8Q Rg6 38.Qc8+ Ka5 39.Qc7+ Ka4 40.Rg7 Rxg7 41.Qxg7 a5 42.Qd4+ b4 43.cxb4 Black lost on time, dzomba - VendettaA, lightning [!], FICS, 2006.
6...g6 7.Nxg6
7...hxg6
Here we have another dispute.
Stockfish 6 prefers 7...Nxc2+, suggesting that after 8.Kd1 hxg6 (8...Nxa1? 9.Nxh8+ Ke7 10.Qe5#) 9.Qxg6+ Ke7 10.Qg5+ (Houdini prefers 10.Kxc2 with an edge for White) 10...Ke8 11.Qg6+ Ke7 12.Qg5+ White draws by repeating the position (Houdini prefers 12.Kxc2 with an edge for White).
8.Qxg6+
A number of years ago I got away with the weaker 8.Qxh8?! after 8...Nh6 when 8...Nxc2+, instead, would have led to an edge (Houdini) or an advantage (Stockfish 6) for Black after 9.Kd1 Nxa1 10.Qxg8 in perrypawnpusher - tampajake, blitz, FICS 2009 (1-0, 12).
8...Ke7 9.Qg5+ Nf6
Here Stockfish 6 says Black has the advantage, while Houdini 3 says the position is equal.
Both prefer the text to 9...Ke8 of perrypawnpusher - adamzzzz, blitz, FICS, 2009 (1-0, 39).
10.Qc5+
Better than 10.e5 of perrypawnpusher - JokeritT, blitz, FICS, 2010 (1-0, 28).
10...d6
Stockfish 6 slightly prefers 10...Ke8 to the text, while Houdini 3 thinks 10...d6 is better.
11.Qxd4 Be6
Here, Houdini 3 likes White, while Stockfish 6 prefers Black.
Of course.
For the record, I have also seen:
11...c5 in perrypawnpusher - foreverblackman, blitz, FICS, 2010 (1-0, 21) and perrypawnpusher - vlas, blitz, FICS, 2010 (0-1, 23);
11...Qd7 in perrypawnpusher - theferno, blitz, FICS, 2010 (1-0, 28);
and 11...Bg7 in perrypawnpusher - Raankh, blitz, FICS, 2010 (1-0, 49).
12.Nc3
Also possible is 12.f4 c5 when again Houdini 3 likes White, while Stockfish 6 likes Black.
12...Bh6 13.d3 Bxc1 14.Rxc1
Both Stockfish 6 and Houdini 3 suggest 13...c5 first, to displace the White Queen.
White has four pawns for his sacrificed piece. Even if the position is "objectively" even, his prospects are good at club play level.
The next few moves show that both players are blind to some tactical possibilities, however.
14...Qg8 15.g3 Bh3 16.Nd5+?! Nxd5 17.Qxd5? Qxd5 18.exd5 Rae8
Both players overlook the fork 18...Bg2! when Black can grab a pawn and increase Kingside pressure after 19.Rg1 Rxh2 20.c4 Rf8.
19.Kd2 Kd7 20.c4 Re7 21.f4 Rhe8 22.Rce1 Rxe1 23.Rxe1 Rxe1 24.Kxe1
Both computer programs see the position as equal.
What follows goes along with suggestion that a bad plan is better than no plan at all - which is a nice way of saying that my bad idea worked, while my opponent missed some good ideas.
24...Bg4 25.Kf2 Ke7 26.Kg2?! Kf6?!
Black is worried about stopping the Kingside pawns, when he probably should look at using his Bishop to capture a couple of center pawns: 26...Be2 27.d4 Bxc4 28.a3 Bxd5+ 29.Kf2 b6. After this, Black can look to create his own passed pawn, which should counter White's activity.
27.h3 Bd7?!
Again, 27...Be2 was to be preferred. Black's Bishop has to cut down the number of enemy pawns before they become a real problem.
28.g4 Bxg4
This is tantamount to resignation. White can now develop play on both wings. At least one passer is bound to get through.
29.hxg4
29...a6 30.Kf3 c5 31.dxc6 bxc6 32.Ke4 Kg6 33.d4 a5 34.b3 Kf6 35.a3 Kg6 36.b4
Black resigned
The other day I woke up too early, and said to myself, "Let's have a chess game, and then a cup of coffee."
Wrong.
I needed the coffee first.
perrypawnpusher - igisr
blitz, FICS, 2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.0-0 Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6 8.Qd5+ Ke7
I have played games where Black has chosen 8...Ke8, 8...Kf8 and even 8...Kf6, but the text move was new to me. (There is only one game example in The Database.)
There is something significant about the placement of the Black King, but in the morning mental fog, it eluded me.
9.Qxc5+ d6 10.Qe3 Nf6 11.f4 Re8
Instead, the game mrddblack - ammagamma (1-0, 32), continued 11...Rf8.
12.f5 Ne5 13.d4 Nc4
Routine, but probably better was 13...Nc6.
14.Qd3 b5 15.Nc3
After the game, Stockfish recommended the straight-forward 15.b3 Nb6 16.e5 dxe5 17.dxe5 Qxd3 18.exf6+ Kxf6 19.cxd3 with a slight advantage for White.
The text move is not "wrong", but it reflects the fact that I believed that e4-e5 was not currently playable because it allowed the exchange of Queens - missing, as Stockfish showed, that White can use the zwischenzug exf6+ after ...Qxd3 to regain his sacrificed piece.
15...a6 16.b3 Nb6 17.Ba3
Hoping that the pin on Black's d6 pawn will allow White's e-pawn to advance, but this is cloudy thinking, and easily evaded. Better was the simple 17.e5 dxe5 18.dxe5 Qxd3 19.exf6+ Kxf6 20.cxd3 as we have seen.
17...Kf7 18.Rae1
A standard move in this kind of position, but I could not escape the feeling that I had missed something...
18...Bb7 19.Bb2 b4
White's pawn center is now crumbling under the pressure of Black's pieces (and the b-pawn), but I was confident that I had everything under control.
20.Qc4+ Nxc4
Or not. White resigned.
I had a cup of coffee while I did the post mortem.
As updated in "Shelter in Place", I raced to the top of my first round group (without playing a Jerome Gambit) in an Italian Game tournament at Chess.com, completing my games - only to have to wait until others in my group finished theirs.
Lvercotti surged ahead of me, eventually taking first place in the group with a score of 10-0-2. Next came mikerj, galloping by with 8-2-2. I managed a draw off of each of them.
At 7-2-3 I could only wait for the outcome of the last-to-finish game in our group, FedorMarkov - Lvercotti, to see if White won, also reaching 8.5 points, possibly knocking me out of third place - and a chance to advance to the second round of the tournament - on tiebreaks.
Curiously, in a R + 5Ps vs R + N + 2Ps, where the position was balanced, but White seemed to have all the winning chances - the first player lost on time. Given that the time limit was 3 days per move, something must have gone wrong for him...
Group 2 has yet to finish, although it is already clear that will_thrash, 7thSon and Diogenes_of_Sinope will all advance to the second round, in some kind of order, as the trio has broken away from the rest of the pack.
With luck, Round 2 will see some Jerome Gambits.
Playing over lost games, or games where I played poorly, provides plenty of lessons for my chess improvement. The following game has a shelf-full of lessons for both me and my opponent - especially when it comes to middle game play.
perrypawnpusher - genericme
blitz, FICS, 2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+
The Italian Four Knights Jerome Gambit. I have 57 examples of this position in my games in The Database, scoring 73%. (That seems pretty good, but it's below the 81% I have scored with the regular Jerome Gambit; the 89% with the Semi-Italian Jerome Gambit; and the 92% with the Blackburne Shilling Jerome Gambit.)
5...Kxf7 6.Nxe5+ Nxe5 7.d4 Nd3+
This is a creative idea from my opponent, and a TN according to The Database. It is the kind of "shocking" move that can be found in blitz games, and I admit that I was expecting the regular (and stronger) 7...Bxd4.
8.Qxd3 Bb4
Black moves the threatened Bishop, and puts pressure on White's e-pawn. Ceteris paribus, such an idea should work - but "all things" are not "equal" here, as White's sacrifice of a Bishop at f7 has moved Black's King. Concrete analysis is important, even in blitz.
After 8...Bb6 9.e5 Ne8 10.O-O d6 11.f4 White could feel that his "Jerome pawns" would balance out Black's extra piece.
9.Qc4+ Kg6
Playing over this game afterward, I am sure my opponent will decide that 9...d5 10.Qxb4 Nxe4 would have been better than exposing his King further.
10.Qxb4 Re8
I had expected 10...Nxe4 11.Nxe4 Re8 when I planned on castling, although now, after the game, it seems that 12.f3 d5 13.O-O dxe4 14.Bf4 is the way to go.
11.O-O Ng4
After the game, I looked at 11...Nxe4 with Stockfish, which recommended for White something I had not considered: 12.d5!?
analysis diagram
The strength of the move - among other things, threatening to win the Knight at e4 - slowly becomes apparent.
For example, Black cannot simply hope to exchange with 12...Nxc3, as 13.Qg4+ Kf7 14.Bg5 would allow White to win the exchange (as well as recapture on c3).
Protecting the Knight with 12...Qe7 seems best, but, again, after 13.Qxe7 Rxe7 14.Re1 Nxc3 15.Rxe7 Nxd5 16.Re5 Nf6 White has won the exchange.
And if Black simply retreats the Knight with 12...Nf6, Stockfish recommends the consistent 13.d6!?
analysis diagram
It will be a long while before I play chess like that, though!
12.Bf4 Qh4
I am afraid that me playing the Jerome Gambit (giving "Jerome Gambit odds") seemed to have convinced my opponent that I was even less skilled than I actually am. Here he goes ahead with an attack that I had already prevented with my last move. Instead, 12...d6 would have been better, but White would have the advantage.
13.Bg3 Qh5 14.f3
The text move consolidates White's position - which was the psychological need I had at the time - while Stockfish, later, suggested that 14.Nd5!? would have deeply troubled Black's. The closer you look, the stronger it appears.
14...Ne3
This is about as good as any other move. Black's game unravels from here, as he seems to give up hope.
15.Rf2 Nxc2 16.Rxc2 a5 17.Qc4 d6 18.Nd5 Be6 19.Nf4+ Kg5 20.Nxe6+ Kg6
Everything leads to material loss and checkmate.
21.Nf4+ Kg5 22.Nxh5 Black resigned.
Alonzo Wheeler Jerome was not only the inventor of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), he was an ex-Civil War soldier ("Organized at Riker's Island, NYC on February 27th 1864, the 26thRegiment [U.S.C.T.] served three years in the Department of the East to March, 1864 and in Port Royal, SC in the District of Beaufort, Department of the South, until April, 1865. The 26th was honorably discharged and mustered out, under Colonel William B. Guernsey on August 28th, 1865." ) and a hard-working hemp farmer, holding several patents related and unrelated to his work.
He also wrote The Great Debate, subtitled A Platform Scene in the Seven Joint Discussions between Lincoln and Douglas. One of the Relief Pictures in the Dome of the State Capitol at Springfield, Illinois, (1899).

A propos the "Sarratt Attack" which I have looked at in a few posts on this blog, I should have mentioned the three-part series of articles at chess.com by "mikrohaus2014" which gives excellent historical and analytical coverage: Parts 1, 2, and 3.
