Blackburne Shilling Jerome Gambit Mystery

I have added to The Database some more Jerome Gambit (and Jerome-ish) games played online at FICS from the first quarter of 2020. Making my way through some of them, I came upon a small mystery.

Here is the game. By the way, drumme is well-versed in the Jerome Gambit, having 589 games in The Database, scoring 55%.

drumme - talyprossoneri
4 0 blitz, FICS, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nx6 hxg6 8.Qxg6+ Ke7 9.d3 Black resigned

Black's resignation is puzzling. He has two extra pieces for four pawns - perhaps a practical challenge in a 4-minute game (for the record, in the 45 games in The Database with this position, Black won only 16, and drew 2) - an advantage that Komodo 10 assesses at about a pawn and a half.

Maybe the outside world intruded to call him away. 

If the reason was chessic, I can make a guess. Suppose talyprossoneri was intending on playing the pawn capture and fork 9...Nxc2+, followed by 10.Kd1 Nxa1 - when he suddenly realized that his opponent would then have 11.Bg5+, as in paddjaa - vlas, blitz, FICS, 2011, which would lead to checkmate after 11...Nf6 12.Qxf6+ Ke8 13.Qg6+. Ouch.

However, Black did not have to go after the poisoned Rook, as he had at least two other reasonable moves to consider.

The first was 9...Ne6, although, after 10.Bg5+ Nxg5 11.Qxg5+ Black still has to solve the problem of the f6 square and the d8-h4 diagonal. A 1-minute game, jollygeoff - brouchek 1 0 lightning, FICS, 2016, finished things off from that position with 11...Kf7? 12.Qxd8 and Black resigned a few moves later. The proper response was 11...Nf6, as after 12.e5 Kf7 13.exf6 Qxf6

Black's two Bishops (one, the extra piece) are probably better than White's three extra pawns.

The second choice for Black is the somewhat stronger (according to Komodo 10) 9...Nf6, as long as the defender meets 10.e5 with 10...Ke6!? (Instead, 10...Ne8? was seen in KingAsh - NightEagle, 1 0 lightning, FICS, 2015 [1-0, 40, time forfeit], when the game should have continued with 11.Bg5+, again leading to checkmate). Best, then, for White would be 11.exf6 Qxf6, as opposed to 11.0-0, from GOH - gruzanin, blitz, FICS, 2013 (1-0, 42, time forfeit).




Analysis position







In club play, of course, in both cases, White might have some practical chances with his three passed, connected passed pawns against the enemy Bishop. Especially, as we have seen in some of the example games, time appeared to be on the attacker's side.

Jerome Gambit: Important Win

If SeinfeldFan91 wins the current RedHotPawn.com Jerome Gambit tournament, it will be in part due to his second round win over his main rival for top honors.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+


4...Kxf7 5.c3 h6

White chooses a "modern" Jerome Gambit variation, playing something other than the "classical" 5.Nxe5+.

Black's defensive pawn move has risks as well as benefits.

6.b4 Bd6

The text is maybe a little bit better than 6...Bb6. Two examples: 7.b5 Na5 (7...Qf6 8.bxc6 dxc6 9.d4 exd4 10.cxd4 Bg4 11.Qb3+ Ke8 12.Nbd2 Rd8 13.O-O Bxd4 14.Nxd4 Qxd4 15.Rb1 b5 16.Qg3 Nf6 17.h3 Be6 18.Nf3 Qxe4 19.Qxg7 Rf8 20.Re1 Qd5 21.Bxh6 Rf7 22.Qg6 Rdd7 23.Ng5 Kd8 24.Rxe6 Black resigned, Wall,B - Albertasss, Chess.com, 20108.Nxe5+ Ke6 9.Qh5 Qf6 10.d4 d6 11.Ng6 Rh7 12.Qd5+ Kd7 13.Ne5+ Ke7 14.Qxg8 dxe5 15.Ba3+ Kd7 16.Qxh7 exd4 17.O-O dxc3 18.e5 Qf7 19. e6+ Qxe6 20.Qxg7+ Ke8 21.Qf8+ Kd7 22.Rd1+ Black resigned, Wall,B - Guest2359830, PlayChess.com, 2015.

7.b5

Another idea: 7.Qb3+ Kf8 8.d3 Nf6 9.O-O Qe7 10.Be3 Qe6 11.Qc2 b6 12.Nbd2 Bb7 13.d4 exd4 14.Nxd4 Nxd4 15.Bxd4 Qxe4 16.Nxe4 Nxe4 17.Qd3 Re8 18.f3 Ng5 19.Rae1 Rxe1 20.Rxe1 Be7 21.Qf5+ Ke8 22.Bxg7 Rg8 23.Qf6 Kd8 24.Qxe7+ Kc8 25.Bf6 Ne6 26.Rxe6 dxe6 27.Qxe6+ Kb8 28.Qxg8+ Bc8 29.Qd8 Kb7 Black resigned, KingAsh - Nineyes, FICS, 2015

7...Na5 8.d4 Qf6

Overlooking a tactic based on Black's King being on f7.

9.dxe5 Qe6 

Now he sees it: if 9...Bxe5 then 10.Qd5+ will win the Bishop. As it is, White wins back the piece anyhow.

10.exd6 Qxe4+ 11.Be3 Nc4



Black gets some pressure, but it is not enough.

12.Nbd2 Nxd2 13.Qxd2 Nf6 14.dxc7 Ng4 15.O-O Re8



It is useful to point out Black's light-squared Bishop, still on its home square, blocking the Queenside Rook.

16.Bd4 d6 17.Rfe1 Qd5 18.Qf4+ Bf5 19.c4 g5 20. Qxg4 Bxg4 21.
