Jerome Gambit: Educational (Part 4)

 

As I have mentioned

In a couple of previous posts ("Jerome Gambit: Unbeatable Gambit!?" and "Jerome Gambit: Educational (Part 1)") I mentioned a YouTube video (again, thanks for the information, Mikka Eckkinen) featuring Canadian Grandmaster Aman Hambleton playing a couple of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games.

It turns out that the grandmaster played three Jeromes against his opponent, a FIDE master (although very close in Chess.com rating).

Here is another Jerome Gambit game that did not appear in the video. Again, it can be a challenge to defeat a strong opponent with a so-called "refuted" opening.

 

KNVB - TampaChess

3 0 blitz, Chess.com, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8

For the third time, the FIDE Master chooses Jerome's defense to the Jerome Gambit.

7.Qxe5 d6 8.Qg3 Nf6 9.d3 Kf7 10.Nc3 Rf8 11.Bd2 

Varying from putting the Bishop on e3, as in the two earlier games.

11...Kg8

Completing the castling-by-hand.

12.Na4

Another way to deal with that annoying Bishop on c5. This is risky, as the f2 square is vulnerable, as Black immediately shows.

12...Nh5 13.Qg5 Bxf2+ 14.Kd1 Qxg5 15.Bxg5 Bg4+ 16.Kd2 h6 17.Be3 

After all.

17...Bxe3+ 18.Kxe3 Nf4

White's active King and extra pawn do not balance Black's extra piece.

19.Rhg1 c5 20.Nc3 Rae8 21.Raf1 g5 22.Kd2 

22...Rd8 23.a4 a6 24.a5 Kg7 25.b3 d5 26.exd5 Nxd5 27.Ne4 Rc8 28.h3 Bh5 29.Rxf8 Kxf8 30.Rf1+ Ke7 31.Re1 Kf8 32.Rf1+ Kg7

The grandmaster works to extract what he can from his position. 

 33.Nd6 Rc7 34.g4 Bg6 35.Re1 Rd7 36.Nc4 Nf4 37.Re5 Nxh3 38.Rxc5 Nf2 39.Ne5 

Attacking the enemy Rook, protecting the g-pawn - but missing something.

39...Ne4+ 40.Ke3 Nxc5 41.Nxd7 Nxd7 42.c4 h5 43.d4 h4 White resigned

As we have seen in an earlier game, White's pawns will be stopped, but Black's h-pawn will not.

Jerome Gambit: Educational (Part 3)

As I mentioned last post ("Jerome Gambit: Educational (Part 2)")

In a couple of previous posts ("Jerome Gambit: Unbeatable Gambit!?" and "Jerome Gambit: Educational (Part 1)") I mentioned a YouTube video (again, thanks for the information, Mikka Eckkinen) featuring Canadian Grandmaster Aman Hambleton playing a couple of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games.

It turns out that the grandmaster played three Jeromes against his opponent, a FIDE master (although very close in Chess.com rating).

Here is a game that did not appear in the video. It is a 3-minute blitz game, and the time control alters plans a bit.

I mean no disrespect to the grandmaster by showing a loss with the Jerome Gambit - it can happen when you play a "disreputable" opening at high speed; and the game is still educational, especially the endgame.

 

KNVB - TampaChess

3 0 blitz, Chess.com, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

The Jerome Defense to the Jerome Gambit, introduced by Alonzo Wheeler Jerome in 1874, which TampaChess played in the previous game as well. 

7.Qxe5 d6 8.Qg3 Nf6 9.Nc3 Kf7 10.d3 Rf8 11.Be3 Bxe3 12.Qxe3 Kg8 13.0-0 d5

Except for a few changes in move order, this game follows the path of the previous one, up to this point. It looks like TampaChess has reflected upon his previous 13...a6 (by transposition) and decided more actively to strike at White's pawn center.

White is not interested now in 14.exd5, but the threat to fork two pieces means he has to move one of them - giving Black the opportunity to exchange.

14.Qg3 dxe4 15.dxe4 Qe7 16.Rfe1 c6 17.a3 Be6 18.Rad1 Rad8 19.f3 

White relents and protects the e-pawn with the f-pawn.

19...Rxd1 20.Rxd1 Rd8 21.Rxd8+ Qxd8 22.Qe5 

White is counting on his Queen's activity to help even things despite the material imbalance (two pawns vs a Bishop).

Black would like an active Queen - to pursue checkmate.

22...Bc4 23.b3 Qb6+ 24.Kh1 Qf2 25.h3 Bf1 26.Qh2 Qxc2 27.Na4 b6 28.Qb8+ Kf7 29.Qc7+ Ke8 30.Qc8+ Ke7 31.Qc7+ Nd7 32.Qg3

Defending and attacking.

 

32...Qxg2+ 

Instead, 32...Qxb3 looked safe enough, despite 33.Qxg7+, but I am not the one facing a grandmaster with my clock ticking down.

33.Qxg2 Bxg2+ 34.Kxg2 Ne5

The idea: the better placed Knight, a more centralized King, the Queenside pawn majority. It may not be enough to win, but it should not lose.

35.b4

Against 35...c5. Repositioning the Knight (to b2, to keep the enemy Knight off of c4) might have been better.

35...Nc4 36.Nc3 Nxa3 37.Kf2 Nc2 38.b5 Nd4 39.bxc6 Nxc6 

Things look difficult here for White, but there is a reason that Grandmaster Hambleton plays 3-minute blitz (besides the fun and excitement) - he is very good at it.

40.Ke3 Ne5 41.Nd5+ Kd6 42.f4 Nf7 43.Kd4 Nd8 44.e5+ Kc6 

Should the Black King protect his pawns and help them to advance, or stay in front of White's pawns and hinder them?

Stockfish 15.1 suggests 44...Ke6, instead, looking at 45.Nc7+ Kd7 46.Nb5 Ne6+ 47.Ke4 a6 48.Nd6 g6 49.f5 gxf5+ 50.Kxf5 Ng7+ 51.Kf4 Kc6 52.Ke4 b5 53.h4 Ne6 54.Kf5 Nc7 55.Ke4 a5 56.Kd4 Ne6+ 57.Kc3 Nf4 58.Ne4 a4 59.Ng5 Nd5+ 60.Kb2 when Black would be winning.

45.Ke4

The split-second decisions can cut against you. The computer likes 45.f5 a5 46.e6 Kd6 47.Nxb6 Nxe6+ and the game will be strangely even and likely drawn, i.e. 48.Ke3 Ke7 49.fxe6 g5 50.Ke4 Kxe6 51.Na4 Kf6 52.Nb6 Kg6 53.Kf3 Kf5 54.Kg3 h5 55.Kf3 Kf6 56.Kg3 Kf7 57.Na4 Ke6 58.Nb6 Kf6 59.Kf2 g4 60.hxg4 hxg4. Wow.

45...g6 

Arrrggghhh.

46.f5 gxf5+ 47.Kd4 Ne6+ 48.Kc4 b5+ White resigned

White's pawns are not going anywhere; Black's are.

Jerome Gambit: Educational (Part 2)

In a couple of previous posts ("Jerome Gambit: Unbeatable Gambit!?" and "Jerome Gambit: Educational (Part 1)") I mentioned a YouTube video (again, thanks for the information, Mikka Eckkinen) featuring Canadian Grandmaster Aman Hambleton playing a couple of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games.

It turns out that the grandmaster played three Jeromes against his opponent, a FIDE master (although very close in Chess.com rating).

Here is the second game from the video.

 

KNVB - TampaChess

3 0 blitz, Chess.com, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

The Jerome Defense to the Jerome Gambit, given in the Dubuque Chess Journal, July 1874, ("Jerome's Double Opening Third Variation") by Alonzo Wheeler Jerome.

7.Qxe5 d6 8.Qg3 Nf6 9.d3 Kf7 10.Nc3 Rf8 11.O-O a6 12.Be3 Bxe3 13.Qxe3 Kg8 

So far, Black has shown restraint, focusing on castling-by-hand and keeping White's Knight from adventures (i.e. 11...a6).

White will use his actively placed Queen and "Jerome pawns" to stir up trouble.

14.Qg3 Nh5 15.Qe3 Nf4 16.g3 Nh3+ 17.Kg2 

Is this a prelude to a trap?

Apparently Stockfish 15.1 prefers 17.Kh1 on principle - as if computers had principles (although perhaps that is part of their programming) - but the grandmaster is more knowledgeable about human nature.

17...Ng5 18.h4 Bh3+ 

Although attractive at first glance - and 3-minute games have a lot of "first glances", as Stockfish's predecessor, HAL the computer, said in "2001: A Space Odyssey" (1968), this "can only be attributable to human error."

19.Kh2 Rf3 20.Qxg5 Qxg5 21.hxg5 Bxf1 22.Rxf1 Raf8 

White has two pawns for the exchange. It is educational to play through the game and see how he takes advantage of this small material plus.

Keep in mind that if the game lasts 30 moves, the players will average no more than 6 second a move thinking time; and if it lasts 60 moves, that average will drop to 3 seconds per move.

Good players play good moves, even while under pressure.

23.Kg2 c6 24.Ne2 R3f7 25.f4 g6 26.Nd4 Re8 27.Nf3 Kg7 28.Nh2 h5 29.gxh6+ Kxh6 30.a4 Kg7 31.Nf3 b6 32.Nd4 c5 33.Nf3 b5 34.Ra1 c4 35.axb5 axb5 36.Nd4 cxd3 37.cxd3 Rc7 

White's Rook has an open file and it and the Knight help guard entry points to the file that Black's Rook has.

Now, White can pawn hunt, even as the Kings become more active.

38.Ra6 Rd7 39.Kf3 b4 40.Rb6 g5 41.Rxb4 Rh8 42.Rb5 Kf6 

43.Rf5+ Ke7 44.Rxg5 Rh2 45.b4 Kd8 46.Rd5 Kc7 47.Nb5+ Kc6 48.Nd4+ Kb6 49.Nf5 Kc7 50.b5 Rb2 51.Nd4 Rb1 

White's threatening b-pawn temporarily ties down Black's Rook and King, while White's Knight proves annoying both on attack and defense.

There needs to be another distraction, and White has it. 

52.f5 Kb6 53.Ne6 Rf1+ 54.Ke2 Rb1 55.Kf2 Rb2+ 56.Kf3 Rxb5 57.Nf4 Rc5 58.Ke3 Rc1 59.g4 Re1+ 60.Kf2 Ra1 

I didn't say that it was going to be easy.

Stockfish 15.1 assesses White as almost two pieces better.

Oh, and time management is an issue, too.

61.Rd4 Kc6 62.Ke3 Re1+ 63.Kd2 Ra1 64.Ne6 Ra2+ 65.Ke3 d5 66.Rxd5 Rxd5 67.exd5+ Kxd5 

68.Nf4+ Ke5 69.d4+ Kf6 70.Ke4 Ra1 71.Ne6 

71...Re1+ 72.Kd5 Ke7 

Black's Rook has done a good job defending from behind the enemy pawns, but here - under serious time pressure - the defender slips.  The silicon advisor sees 72...Rg1 73.Kc6 Rxg4 74.d5 Kxf5 75.Nc5 Rg6+ 76.Kc7 Ke5 77.Nd3+ Kxd5 78.Nf4+ Kc4 79.Nxg6 with a draw, as White will not be able to checkmate with just a Knight..

73.g5 Ra1 74.Nf4 Ra5+ 75.Ke4 Ra6 76.Nd3 Kd6 77.Ne5 Ra2 78.f6 Re2+ 79.Kf4 White won on time, in a won position

A heart-pounding conclusion.

Jerome Gambit: Educational (Part 1)

Here is the first of the two Jerome Gambit (1.e4 Nc6 2.Nf3 e5 3.Bc4 Bc5 4.Bxf7+) games by Canadian Grandmaster Aman Hambleton mentioned in the earlier post "Jerome Gambit: Unbeatable Gambit!?"

It is well worth playing over, from the opening through the middlegame to an interesting endgame. Grandmaster play is educational at any speed.

Grandmaster Hambleton's opponent is a FIDE Master. I do not know how many Jeromes that Praschess has played or defended against, but he gives a good account of himself.

KNVB - Praschess

11.d3 Re8 12.O-O Kg8 13.Qg3 c6 14.f4 Qe7 15.f5 Ne5 16.Bg5 

The Database has 22 Jerome Gambits played by KNVB - 20 wins.

16...Nf7 17.Bd2 Qe5 18.Qh4 Bd7 19.Rae1 Qe7

20.h3 b5 21.a3 a5 22.Ne2 d5 23.Ng3 dxe4 24.dxe4 Ne5 25.Kh1 Qf7 26.Bg5 c5 

27.Rd1 b4 28.Rd6 Bb5 29.Rfd1 Nc4 

Tempting, to evict the enemy Rook, but it's stay was temporary, anyhow.

30.Rxf6 gxf6 31.Bxf6 Ra6 32.Qg5+ Kf8 33.Qh6+ Kg8 34.Qg5+ Kf8 35.Qh6+ Kg8 

White has a draw if he wants it, and with only 3 pawns for a Rook it would be understandable if he took it - but Black's offside pieces suggest that there might be more for White in this position than just 1/2 a point.

Stockfish 15.1 evaluates White as about a pawn better.

36.Nh5 Ne5 

Rushing reinforcements to the front, but this is a mistake. Better was to threaten an exchange of Queens with 36...Qf8. But, of course, I am sitting at my desk with all the time in the world.

37.Qg5+ Ng6 38.e5 Be2 

Things have gotten quite wild.

39.Nf4 

The computer recommends 39.e6 Raxe6 40.fxe6 Rxe6 41.Rd8+ Re8 42.Ng3 Rxd8 43.Bxd8 Bb5 44.Bxa5 Bc6 45.Qxc5 bxa3 46.bxa3 Qd5 47.Qxd5+ Bxd5 but that is a lot to see when the clock is ticking. White does not want a pawns-up endgame, he wants to attack.

39...Bxd1 40.fxg6 hxg6 41.Nxg6 Rxf6 42.exf6 Re1+ 43.Kh2 

43...Qc7+

Black is feeling aggrssive, too. He probably should have looked for calmer waters with 43...Kh7 44.Ne5 Rxe5 45.Qxe5 Bxc2 46.axb4 cxb4 47.Qxa5

The rest of the game was played at breakneck speed, as both clocks ticked off their last seconds.

44.Nf4+ Kf8 45.g3 Re2+ 46.Nxe2 Bxe2 47.Qh6+ Ke8 48.Qe3+ Kf7 49.Qxe2 Kxf6 50.Qf2+ Kg6 51.axb4 cxb4 52.c3 White won on time

The position is about even, but the clock has the final say.

Jerome Gambit Magic

Sometimes a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game unfolds with a sense of magic about it, as if the gambiteer simply walks past dangers to his win.

The following game is a fun example.

Chalcinos - 3mad7mdy

10 0 blitz, Chess.com, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3

This is a routine Jerome Gambit position. Perhaps White, familiar withe the opening, arrived at it a with few ticks on the clock.

9...Nf6 10.O-O Ng4 

Many Black pieces feel an immediate need to attack White's Queen, especially since she has been wandering the board, causing further dislocation of his game.

10...Ng4 does not surrender all of his advantage. It could be part of a plan for both Knights to corral Her Majesty - if the follow-through is done right.

11.Qh3

This new move has its risks. Did White anticipate his opponent's sacrifice? Or did he simply see himself passing through the complications, unscathed?

11...Nxf2 

Black takes advantage of the uncovered attack on the Queen to grab one - and then another - pawn.

It is an attractive idea, but the real danger was with 11...Nf4!? when White is going to lose material. One example of the possibilities is 12.Qf3 (Stockfish says this is best) Rf8 13.Nc3 (covering the e2 square) Nxh2 14.Qg3 (capturing the Knight 14.Kxh2 allows 14...Qh4+ 15.Kg1 Nh3+ and White must give up his Queen after all) Nxf1 15.Kxf1 Qf6 and White is only down a Rook.

12.Qb3 Nxe4 

Having said A, Black now says B.

The attack would continue if Black ignored the pawn grab, and instead offered a piece with 12...Nh3+ 13.gxh3 Qh4. 

13.Qf7 checkmate

Presto!
