A GM Faces the BSJG: Not Quite (Part 4)

[continued from previous post]

Regarding the early Blackburne Shilling Jerome Gambit game that we have been looking at ("A GM Faces the BSJG: Not Quite, Parts 1, 2 and 3"), Nater, Carl - Rogers, Ian, Begonia op 09th, Ballarat, 1975 (0-1, 46 ), I was able to contact GM Rogers, who, in turn, was able to contact Mr. Nater.

Not surprisingly, GM Rogers said that he was shocked to see his 1.e4 e5 2.Nf3, Nc6 3.Bc4 Nd4 met by 4.Bxf7+!?. At first, he expected simply be able to refute the move, as he not had it played against him previously - and actually had not even seen it mentioned before. He settled himself down and outplayed his opponent, for the full point.

"I gave up 3...Nd4 soon after that game for multiple reasons, not least that it was a bad move!" was GM Rogers' assessment.

Mr. Nater, rather than claiming to be one of the world's foremost experts on playing the Blackburne Shilling Jerome Gambit over-the-board, modestly reported that "my openings at my prime [around ’75 probably] may have dived as deep as 4/5 moves before descending into chaos ... nowadays worse still." Not surprisingly, he did not have access to game score sheets from 45 years ago, so he could not say if he had repeated (or was repeating) his moment of chess opening inspiration.

"But there doesn't seem to be too much wrong with 4.Bxf7, more wrong with 3...Nd4" was his assessment.

My thanks to GM Rogers and Mr. Nater, for their comments - and for producing a very interesting game!

A GM Faces the BSJG: Not Quite (Part 3)

[continued from previous post]

We continue to examine how a future GM handles the Blackburne Shilling Jerome Gambit.

Nater, Carl - Rogers, Ian
Begonia op 09th, Ballarat, 1975

Black has two pieces for a Rook and three pawns.

9.Na3 d5 10.c3 Qe7 11.O-O 

Bringing the King to safety, although 11.d3 was a bit better.

11...Ne2+ 12.Kh1 Nh5 

White's Queen is stalemated. Nater launches a rescue mission.

13.d4 Be6 14.exd5 

Instead, Komodo 10 prefers some tactics: 14.Re1 Nxc1 15.exd5 Nf4 16.Raxc1 Qg5 17.Rxe6+ Nxe6 18.Re1 Qxd5, siding with White's three pawns versus Black's extra piece.

14...Bxd5 15.Qe5 Qxe5 16.dxe5 Bxa3 17.bxa3 Kf7 

18.Be3 Rh8 19.Rfe1 Bc4 20.Rab1 b6 21.Rb4 Bd3

22.c4 c5 23.Rb2 Nhf4 24.Bxf4 

This helps Black untangle his jumbled up pieces. The computer recommends, instead, 24.Rd2 Rd8, when it is tempting to suggest wholesale exchanges: 25.Rxd3 Rxd3 26.g3 Nd4 27.Bxf4 Rxa3 28.Be3 Rxa2 29.Bxd4 cxd4 30.Rd1 Rxf2 31.Rxd4 Rc2 32.Rd7+ Ke6 33.Rxa7 Rxc4 34.Rg7 and the game should be drawn.

24...Nxf4 25.g3 Ne6 26.Rc1 

He might have done better to protect his passed pawn with 26.f4. The game is beginning to slip away.

26...Nd4 27.Rc3 Be4+ 28.Kg1 Nf3+ 29.Rxf3+ 

A decision that will be understandable to many Jerome Gambit players: White goes with the extra pawns against the extra piece.

In club play, the pawns probably have a practical advantage; but a strong player can use the extra piece to show that he has many targets to attack, that the game is his. 

29...Bxf3 30.Rb3 Be2 31.Rc3 Rd8 

The pieces start to dominate, for example, 32.f4 Rd4 and one pawn will quickly fall.

32.e6+

A trick that Rogers does not fall for: 32...Kxe6 33.Re3+, winning the Bishop.

 32...Ke7 33.Rc2 Bf3 

All of a sudden, threatening checkmate.

34.Rc1 Rd1+ 35.Rxd1 Bxd1 

Again, at first glance, I (a middling club player) would be inclined to take White, here - but Komodo 10 tells the real story, rating Black as more than a Rook ahead.

Rogers' hungry Bishop now cleans up the hapless pawns.

36.f4 Be2 37.Kf2 Bxc4 38.Ke3 Bxe6 39.Kf3 b5 40.g4 c4 41.f5 gxf5 42.gxf5 Bxf5 43.Ke3 Bb1 44.Kd4 Bxa2 45.Kc3 a5 46.a4 b4+ White resigned

Hats off to Carl Nater, for his early play of the Blackburne Shilling Jerome Gambit. I hope to hear from him about the game, and his use of 4.Bxf7+.

Hats off, too, to Ian Rogers, future Grandmaster, for the chess lesson: he was surprised in his own trappy opening, but settled himself down and steadily outplayed his opponent.

A GM Faces the BSJG: Not Quite (Part 2)

[continued from previous post]

In the previous post, I mused

Last year, on this blog, I had a lot of fun looking at the idea of a Grandmaster playing or facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), online or over-the-board... "A GM Faces the Jerome Gambit (Part 1 and Part 2) and "Jerome Gambit: More GMs? (Part 1 and Part 2)"... 

The other day I started wondering: Did any GMs play or face the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+)? That search would be a different kind of task, as the game would have to feature either a rare example of a GM playing the BSG, or, even less likely, a GM playing the BSJG. But my curiosity was piqued... 

A search of The Database did not turn up any games with a player (of either color) rated 2500...

So, I next turned to my ChessBase "Big Database" (almost 6,5000,000 games), and did a search for the starting position of the Blackburne Shilling Gambit, below.

I was shocked to find 12 games where at least one of the players was rated 2500!

Closer examination, however, showed that all of the examples came from the Bird Variation of Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nd4 4.Bc4.

Still searching, however, I checked the online ChessBase Live Database, looking for 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ games, and I came upon one with Ian Rogers playing Black.

Ian Rogers! I knew that name: Australian GM! Amazing!

Well, not quite. The game was played in 1975, a few months before Rogers turned 15, five years before he became an International Master, and ten years before he became a Grandmaster.

Let's look at the game, anyhow, as it is quite educational. 

Nater, Carl - Rogers, Ian
Begonia op 09th, Ballarat, 1975

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

Rogers, the teenager, is feeling frisky. I don't know much about his opponent, Carl Nater (age 35 at the time of the game), but a check on the FIDE website indicates that he had a rating of 1378, so, perhaps Black wished for a quick, trappy win.

Carl Nater, 80, at the 2018 Begonia tournament. He later played at the Victorian Country Championships in 2019. Recent word from GM Rogers is that Nater is still playing chess.

4.Bxf7+ 

This is the earliest game that I have with the Blackburne Shilling Jerome Gambit, predating - by 20 years - Melao Jr, H. - Danilo, Centro Cultural, 1996: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ Kxe4 8.Qh5 Kxd4 9.d3 Bb4+ 10.Nc3 Bxc3+ 11.bxc3+ Kxc3 12.Qc5+ Kxd3 13.Qd5+ Kc3 14.Bd2+ Kb2 15.Qb3+ Kxa1 16.O-O#

4...Kxf7 5.Nxe5+ Ke8

The Database has 2,585 games with position, with White scoring 58%.

6.Qh5+ g6

If 6...Ke7, White would have a checkmate in 5, starting with 7.Qf7+.

7.Nxg6 hxg6 8.Qxh8 Nf6 

Nater opted to capture the Rook, instead of the g-pawn (with check), relying on the gain of material. 

Rogers skipped the wild 8...Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 which might have given him an edge, opting, instead, for reasonable development.

Komodo 10 now sees the position as about even, with Black's piece balancing out White's 3 extra pawns. Black has a lead in development, but his King will be unable to castle.
