Jerome Gambit: Another Fine Mate

Checkmate - Free gaming icons

The last game of the quartet of selected Jerome Gambits, by CasualGames4ever
Last but not least and techinqually first! My first clash with this opponent set the tone for the rest of our match, we reach the middle game with him still being better, yet I can easily continue whereas he struggles to find decent moves. This quickly leads to a beautiful checkmate, although I would say the first game had the best check mate

CasualGames4ever - Alanvarela10
3 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 

A standard Jerome Gambit position, where White has pawns to advance - and Black needs a plan.

10.O-O Bd7 11.Nc3 Bc6 12.d4 Qe8 13.d5 Bd7 14.f4 c6 



So far, Black is doing fine, and has a small edge. The game is not over yet.

15.f5 Ne5 16.b3 cxd5 17.Nxd5 Nxd5 18.exd5 Qf7 



Attacking White's d-pawn. Black must always be careful, however, when his King and Queen are lined up on the f-file, facing White's Rook.

19.Bb2

Giving the pawn up, as bait. Thematic was 19...f6, as played later.

19...Qxd5 20.Rad1 Qb5 21.Rxd6 Nf7 



The kind of double-threat move (defends, attacks) that comes obviously, in a 3 minute game, but is often insufficient.

22.f6 g6

Black can't take the Rook, but he can't escape checkmate, either.

23.Qe7+ Kg8 24.Rxd7 Rf8 25.Qxf7+ 

A Queen sac finishes the game off.

25...Rxf7 26.Rd8+ Rf8 27.f7 checkmate



Very pretty!

Jerome Gambit: Pawns and Tactics

As I mentioned previously, I received an email and some games from CasualGames4ever
So recently, just now, I played a nineteen game match against a similarly rated opponent in 3+0 blitz. As white in all but one game I played the jerome gambit, linking them all would make this email ridiculously long, so I will only link the ones I thought are the best. 
Unlike the other two this one demonstrates the attacking potential of this opening rather than the positional ideas. I quickly launch the d, e, and f pawns in a brutal assault towards my opponent's king. This proved immediately fatal. 

CasualGames4ever - Alanvarela10

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


4...Kxf7 5.Nxe5+ Kf8 6.O-O d6 

Varying from the 2 earlier games we have seen, where Black captured the Knight at e5.

7.Nxc6 bxc6 8.d4 Bb6 

9.f4 Ne7 10.f5 Ng8 

I was surprised to see that Komodo 10 agreed with this move.

11.Nc3 Qf6 12.Be3 Ne7 13.Qd3 h5 


Hoping to let the Rook work from home.

14.e5 dxe5 15.dxe5 Qxe5 

The pawn was off limits, as White shows.

16.Bxb6 axb6 17.Qd8+ Kf7 18.Qxh8 


19...c5 19.Qxh5+ Kg8 20.Qe8+ Kh7 21.Rf3 Qd4+ 22.Kh1 Nxf5 23.Rh3+ Nh6

27.Qh8+ Kg6 28.Qe8+ Kh7 29.Rf1 Bxc2 30.Rf8 Kh6 31.Rh8+ Bh7 

Different Rook check, different piece block, same result.

32.Qe4 g6 33.Qh4+ Kg7 34.Rxh7+ Kg8 35.Rh8+ Kf7 36.Qh7+ Kf6 37.Ne4+ Ke5 38.Nxd6 cxd6 39.Re8+ Kd4 40.Qxg6 d5 41.Qg4+ Kd3 42.Qf3+ Kc2 43.Qc3+ Kb1 44.Re1+ Kxa2 45.Qa3 checkmate

Jerome Gambit: Even With the Lack of Queens


Here is another Jerome Gambit game by CasualGames4ever. As he mentioned in a recent email
So recently, just now, I played a nineteen game match against a similarly rated opponent in 3+0 blitz. As white in all but one game I played the jerome gambit, linking them all would make this email ridiculously long, so I will only link the ones I thought are the best 
My opponent managed to get a very strong position out of the opening seemingly with a piece for two pawns, yet despite the lack of queens his king proved very unsafe, an aspect I quickly exploited and soon I won material and quickly converted. 

CasualGames4ever - Alanvarela10
3 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Kf8

Like the game in the previous post. The move is as old as Jerome - Brownson, Iowa, 1875 (1/2-1/2, 29).

6.O-O  Nxe5 7.d4 Bxd4 8.Qxd4 Qf6 



The same threat to win White's Queen as we have seen.

9.Qc5+ Qd6 10.Qxd6+ cxd6 11.f4 Nc4 

11...Nf7, as we have seen earlier, but which was actually played later, is safer.

12.b3 Nb6 

13.Ba3 Kf7 14.Bxd6 Nf6 15.Nc3 Re8 


Black has an extra piece (for two pawns) but White's Bishop block's his pawn, which blocks his Bishop, which hems in his Rook...

16.Rae1 a5 

One way to activate the Rook.

17.e5 Nfd5 18.Ne4 h6 19.f5 a4 20. Bc5 axb3 21.Nd6+ Kf8 


22.Nxc8+

This works. 22...f6 was even more explosive.

22...Kg8 23.Nxb6 Nxb6 24.Bxb6 Rxa2


Black misses his chance to make things a bit muddy with 24...bxc2.

25. cxb3 Rb2 26.Re3 d6 27.Bd4 Rd2 28.Bc3 Rc2 29.e6 d5 30.Rd1 b5 31.Rxd5 Rc1+ 32.Kf2 Ra8

Jerome Gambit: Is Black's King Actually Safer At d8?

?????

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) revolves around the question: Is Black's King actually safer at d8? For a while, the surprising answer seems to be Yes, but quickly - this is a 1 0 bullet game - a resounding No takes its place.

Jerome Gambit: Dangers Along The e-File

Danger!

When facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it can be relatively easy to wander into trouble, especially if you underestimate the attacker's chances in that "refuted" opening. In the following blitz game, Black's chances collapse when he overlooks the dangers to his King along the e-file.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Ke8 8.Qxc5 Qe7 9.Qd4 



White's centralized Queen cannot be chased away by Black's Queen's Knight, as it resides on g6. Kicking the Queen with ...c5 is possible, but it will leave Black's d-pawn backward.

10.O-O Nxe4 

This capture is a mistake, but Black's next move compounds his troubles. He should have acknowledged the error with 10...Kd8, surrendering the Knight, hoping to play on, a pawn down.

11.Re1 Qh4

This move only works if White now captures with his Queen, as the subsequent exchange of Queens would limit White's advantage. However...

12.Rxe4+ Qxe4 13.Qxe4+ Ne7 



Down a Queen for a Rook, Black's only chance is a time forfeit - which does not happen.

Jerome Gambit: Help Is Always Appreciated


When winning with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), it is always tempting to attribute our success to the brilliance of the attack. Sometimes, however, the defender contributes as well. In the following game, Black does quite well - until he doesn't.

It is always attractive to attack the enemy Queen. Oddly enough, Komodo 10 recommends, instead, that Black return his King to e6.

Rather than allow the pawn fork d2-d4.

11.Kxf2 Qf6+ 12.Ke2 Qf4 



To exchange Queens, a sound strategy. 

13.d4 Nc4

One of those kinds of oversights that happen in 3-minute games.
