The latest Jerome Gambit game from Vlasta Fejfar comes with a reminder to all defenders: have fun, but do not allow your attention to wander, do not become distracted.
As the following game shows, Black's distraction is followed by his loss.
vlastous - JOHN LEGEND
internet, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 N8e7
An interesting position in the 6...Ng6 variation (with the 7.Qd5+ "nudge"). I am sure that the computers are happy with Black's chances, but I have to point out that in the 20 games with this position in The Database, White has scored 80%.
9.Qc3
Vlasta has also played 9.O-O. See vlastous - Makaviel ,S, internet, 2017 (1-0, 21).
9...d5 10.d3 d4 11.Qc4 Ne5
The computers like this move - but I don't. I can't count the number of times that Black has gotten in trouble in the Jerome Gambit by having one of his Knight's harass White's Queen. Even if we are only talking about the defender's attention wandering, I have to question the play.
12.Qb3 b6 13.f4 N5c6 14.f5 Bb7 15.O-O Qd6
Someone who glanced the game now might say "All Black has to do is castle and he has a crushing position." Ah, but Black can not castle, and he still has to focus and figure out a plan.
16.Bf4 Ne5 17.Na3 a6 18.Nc4
18...N7c6
Oh, Knights, you will be the death of me!
Black dutifully protects his Knight on e5 (on that square for the third time) from a double attack. But, he overlooks something.
19.Nxd6+ cxd6
In a bit of irony, Black now has (only) 2 Knights for a Queen - not nearly enough. White finishes the game quickly.
20.Qe6+ Ne7 21.f6 gxf6 22.Bxe5 fxe5 23.Rf7 Kd8 24.Qxe7+ Kc8 25.Qc7 checkmate
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ...and related lines

Jerome Gambit: A Bit of Strangeness
I just stumbled over a bit of strangeness, which, in the Jerome Gambit world, is saying something.
The "2014 October Giuoco Piano Jerome gambit" tournament at RedHotPawn was actually a two-game match between SeinfeldFan91 (2223) and Swiss Toni (2088).
We have seen SeinfeldFan91's games before.
The games:
SeinfeldFan91 - Swiss Toni
October Giuoco Piano Jerome gambit tournament, 2014
1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Black resigned
Swiss Toni - SeinfeldFan91 - Swiss Toni

1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Kxf7 White resigned
I guess I understand why I couldn't find these games in The Database.

Jerome Gambit: Clobbering Time
Here is another Cliff Hardy game, a bit of magic in a minute (with no increment).
Wow.
Notes are by Cliff.
Cliff Hardy - NN
1 0, lichess.org, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Kf8 8.Qxc5+ Qe7 9.Qe3
Another interesing juncture. I have a feeling Vlahov likes 9.Qxe7+ here (why not have 6 White checks in a row instead of just 5?) and the 2 moves are fairly close to each other in how strong they are. But I think I prefer to keep the queens on, partly as Black's pieces restrict him and can tend to get in each other's way.
9...d6
Black has a slight advantage with this move but Stockfish claims that 9...d5! gives Black a winning advantage.
10.0-0 Nf6 11.Nc3 c6 12.f4 Bd7?
A bit innocuous - 12...d5! 13.d3 would have kept a slight advantage for Black.
13.f5?!
Pushing the Jerome pawns too early can be a mistake as it can make Black's defensive task easier if he blockades them correctly. 13.d4! would have kept a comfortable advantage for White and if then 13...Re8, White ignores the attack on the e-pawn with 14.f5! Nh4 15.Qf4, when the White attack continues to roll along nicely.
13...Ne5 14.d4 Nc4?
Surprisingly a big error. After this, White was building up a big initiative but after 14...Nf7!, Black would have retained a slight advantage as he would have then been well placed to hold up the Jerome pawns from advancing.
15.Qd3 Nb6
The knight on c4 retards White from playing e5, so Black must strive to not retreat from there. After 15...b5 16.b3 though, White is still poised to blast through the centre.
16.Bg5 Re8 17.Rae1
White is ready to start clobbering.
17...Qf7 18.e5 dxe5?!
Makes things worse but Black is losing anyway.
19.dxe5 Nfd5 20.e6 Black resigned.
Stockfish surprisingly rates this as highly as +8.4 for White and I must admit I don't really quite understand it, though White has a clear development advantage and will have a material advantage as well after he captures on d7.

Jerome Gambit: Another Cliff Hardy Blindfold Game
Strong players usually play strong chess, even when playing at fast time controls - or without sight of the board. Especially, too, when they play unusual openings, such as the Jerome Gambit.
Here is a game from Australia's Cliff Hardy, with his own, very educational, notes.
Enjoy!
A couple of recent Jerome Gambits I thought were interesting though they were a bit one-sided and unfortunately, I wasn't playing sensible normal games again - one game I play blindfolded and the other is a lightning game.
Cliff Hardy (blindfolded) - NN
10 0, lichess.org, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
A strong but risky defence.
7.Qf5+
My preferred move but don't know how you feel about this or 7.f4.
7...Kd6 8.f4 Ne7??
Now White has a winning advantage but 8...Qf6 is one way of keeping a very strong position for Black.
9.Qxe5+ Kc6 10.Nc3??
Doesn't look like a blunder but Stockfish claims this gives Black a winning advantage. It likes 10.Qc3!, intending 11.b4 or 11.d4, with a strong attack. 10.d4? is also surprisingly a blunder, after 10...d6, with a winning position for Black.
10...Rf8??
Now White has a winning advantage again. After 10...d6 11.Qh5 b6!, Black has a winning advantage, as his king can escape by b7 if necessary.
11.d4 d6 12.Qh5 Bxd4??
Unfortunately without having created an escape square with ...b6, this move now loses rather abruptly. However, against 12...g6 White has 13.Qe2! (threatening the checkmate that happened in the game), with a winning advantage anyway.
13.Qb5 mate

Jerome Gambit: An Old Friend
The following Jerome Gambit game has an old "friend" - a defensive counter-attacking move that falls to a simple shot by the attacker. It is always good to have this idea in mind, as it can lead to instant happiness.
Wall, Bill - Guest901255
PlayChess.com, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian opening.
4.O-O Nf6 5.Nc3 Bc5 6.Bxf7+
The Semi-Italian Four Knights Jerome Gambit.
This is a familiar opening; The Database says Bill is 23 - 0 against it.
6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 d6
A familiar placement of pieces. White hopes to make use of the tempo granted by Black's ...h6.
10.f4 Nc6 11.Qd3 Rf8 12.Bd2 Kg8 13.Rae1 Bd7 14.Rf3 Nb4
An old friend: Why not harass the enemy Queen? (Black would do better to continue with 14...Be6.)
15.Qc4+
Oh, yeah, that's right...
15...d5 16.Qxb4 dxe4 17.Nxe4 Nxe4 18.Qxe4 Bc6 19.Qe6+ Kh8
White has recovered his sacrificed piece and is a pawn up, with better development. The Bishops-of-opposite-colors whisper of the possibility of a drawn endgame, but they offer interesting tactical ideas in the middle game.
20.Rd3 Qf6 21.Qxf6 Rxf6 22.Re7
It is clear that g7 is going to come under attack.
22...Rc8
Challenging White's Rook with 22...Re8 would lead to 23.Rxe8+ Bxe8 but also 24.Rd8, but that was the right way to go.
23.Rg3 Bd5 24.Rgxg7 Be4 25.Bc3 Black resigned
White has an attack that will lead to checkmate. The best defense, 25...Rg8, has an air of futility after 26.Bxf6.

It is clear that g7 is going to come under attack.

23.Rg3 Bd5 24.Rgxg7 Be4 25.Bc3 Black resigned
White has an attack that will lead to checkmate. The best defense, 25...Rg8, has an air of futility after 26.Bxf6.

Jerome Gambit: Crazyhouse
Dear Readers,
The latest email from Cliff Hardy is a doozie.
Can you imagine playing the Jerome Gambit in a "crazyhouse" game of chess?
Mr. Hardy did.
The following game comes with a warning - "crazyhouse" chess, is kind of "crazy"!
Hi Rick
In saying that, I don't mean to offend Brenda Lee, but it's just that I should not be sending you this game under any circumstances (especially as, for one thing, it is heading on a tangent away from what your blog is about) and I apologise profusely for any anxiety or vexation caused by it.
But I couldn't help it and, besides, you would have figured out sooner or later (if you haven't already) that I belong in the crazy house.
Anyway, speaking of crazyhouse, this is a game I played in a Lichess crazyhouse tournament (crazyhouse is the chess variant where, once you capture a piece, you are able to put that piece back on the board on any empty square at any particular time, though placing it counts as a move).
Lichess actually annotates crazyhouse games using Stockfish.
Lol, I understand if you want to reply to me with something like, "Thanks for the game but please never, ever, ever, ever, ever send me a crazyhouse game again!!" 😉
Cliff Hardy (1884) - NN (1686), Lichess Crazyhouse Tournament, 3 + 2, 2018
1. e4 e5
2. Nf3 Nc6
3. Bc4 Bc5
This is a common crazyhouse opening variation.
4. Bxf7+ Kxf7 [1xP 1xB]
My note on the right there in square brackets means that since White has captured one pawn (i.e 1xP), he now has that pawn "in hand" and can place it on the board when he wishes. The "1xB" in bold is saying that, likewise, as Black has captured one bishop he can place that bishop on the board when he wishes.
5. Nxe5+ [2xP 1xB]
Stockfish doesn't like the Jerome Gambit at all and actually likes it a lot less in crazyhouse than it does it normal chess! It rates the position as around -9.7, but what's a queen advantage between friends?
5. ... Nxe5 [2xP 1xB; 1xN]
6. Qh5+ N@g6? [2xP 1xB]
Stockfish much prefers 6...Kf8, similarly to how it does when White plays the Jerome Gambit in normal chess, but nevertheless still rates this crazyhouse position as -6.6, in Black's favour.
["N@g6" means that Black places the knight that he had "in hand" on the board for his move. Naturally, that means he now only has a bishop "in hand" left (i.e. 1xB)].
7. @f5 Qf6 [1xP 1xB]
[@f5 means to place one of white's pawns that he had "in hand" on the board at f5].
8. d4? [1xP 1xB]
White sacrifices a pawn to speed up development but attacking the queen with @g5 was better, with Black still holding a -4.3 pawn advantage, though with my low standard of crazyhouse play, a piece here or there is not that significant. Cashing in too early with 8. fxg6+?? is even worse than the move I played in the game, since White would then needlessly take the pressure off Black and may allow Black a big counter-attack e.g. 8...hxg6 9. Qxh8?? Qxf2+ 10. Kd1 B@e2 mate.
8. .... Bxd4 [1xP 1xP; 1xB]
9. @g5 Qb6 [ 1xP; 1xB]
10. fxg6+ hxg6! [1xN 2xP; 1xB]
During the game, I thought this was a mistake as it left the rook on h8 unguarded, but Stockfish likes the rook sacrifice for Black as he now has a strong attack on the vulnerable white king.
11. Qxh8 Bxf2+ [1xN; 1xR 3xP; 1xB]
12. Kd1?
Black's advantage blows out from -11.1 to -25.9 after this move. I had been afraid of playing 12. Kf1 because I thought that black could then have gotten a big attack with 12...@e2+? 13. Kxe2 B@g4? but after blocking the check with 14. @f3 (I think I forgot that
White would have had a pawn available to put on f3 as it is the pawn White took with 13. Kxe2), White would then have had a +13.7 advantage, with his and knight and rook "in hand" and safe king .
12. ... Qd4+? [1xN; 1xR 3xP; 1xB]
The position is fairly even after this move but 12...B@g4+ (-25.9) was much stronger since if White then blocks the check with 13. N@f3, Black can take the knight on f3 with check when he wishes and place it on the board with check, to keep the attack going (the initiative, by way of continuous checks, is often of supreme importance in crazyhouse, in order to obtain a forced checkmate).
13. Bd2 Qxe4?? [1xN; 1xR 4xP; 1xB]
13...@d3 is much better and is a typical attacking move in crazyhouse; placing a pawn menacingly on any empty square near the opponent's king.
14. N@d8+ [1xR 4xP; 1xB]
Very strong but the simple fork of king and queen with 14. R@f4!+ (+14.2) was even better, but I had missed that it was a possibility.
14. ... Ke7
15. Nc3
I didn't notice 15. Qxg7+, which is a bit stronger and more forcing.
15. ... @e2+ [1xR 3xP; 1xB]
Black tries in vain to wrest the initiative from White but it is hard work as the white king is actually the much safer of the two kings.
16. Nxe2 @d3 [1xP; 1xR 2xP; 1xB]
17. Qxg7+ Kd6 [2xP; 1xR 2xP; 1xB]
17...B@f7 was an alternative, though after 18. @f6+, White would still have had a huge initiative.
18. Qf8+ Kd5?? [2xP; 1xR 2xP; 1xB]
18...B@e7! would have slowed White's initiative down and made things very unclear.
19. Nc3+
Stockfish finds a mate in 4 here with 19. R@b5+ c5 20. Nc3+ Kc4 21. b3+ Kd4 22. Qxc5 mate.
19. ... Kd4
Black is forced to bring his king even further down the board into an extremely precarious position.
20. Qxf2+ [2xP; 1xB; 1xR 2xP; 1xB]
Stockfish finds another mate in 4 here with 20. Nb5+ Kd5 21. Nxc7+ Kd4 22. c3+ Kc4 23. b3 mate.
20. ... @e3 [2xP; 1xB; 1xR 1xP; 1xB]
21. Bxe3+ Qxe3 [3xP; 1xB; 1xR 2xP; 1xB]
Or 21...Kc4 22. R@c5+ Kb4 23. a3 mate.
22. Qxe3+ Kxe3 [3xP; 1xB; 1xR; 1xQ 2xP; 1xB; 1xQ]
23. Nd5+
There were several mates in 2 here e.g. 23. R@e4+ Kf2 24. Q@f1 mate.
23. ... Kd4
24. B@e3+ Kxd5 [3xP; 1xR; 1xQ 2xP; 1xB; 1xQ]
24...Ke4 25. Q@d4+ Kf5 26. Qf4 mate would not have been much better.
25. Q@d4 mate
Sorry again!
Bye,
Me ☺
