Jerome Gambit: Too Clever

Image result for free clip art clever


Here is the latest Jerome Gambit game from the intrepid Cliff Hardy. He plays them online and over-the-board, sighted and blindfold, slow and fast. I have added some diagrams, and one note, but the rest are his.

Hi Rick,

You seem to be getting quite a lot of bullet Jerome Games, but here is another short Jerome Gambit game I played:

Cliff Hardy (2260) - NN (2187)
1 0, Lichess, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 


7.Qf5+ Kd6 8.f4 Nd3+??


I guess it's a bit hard to find the right move in bullet chess! ðŸ˜‰ Not that I have that much idea what the best move was here for Black - I'll leave that up to Rick and the Jerome database to decide! ðŸ˜‰

[I checked The Database, and was surprised to find a dozen games with ...Nd3+ in similar, but not exactly the same, positions. Black returns one of the sacrificed pieces, buries White's dark square Bishop, and plans an attack on the dark squares. Still, the Knight move is a bit too clever - although it appears that no one has yet played the best alternative, the walk-away 8...Kc6!? - Rick]

9. cxd3

White now has a clear advantage, according to the Lichess Stockfish analysis feature.

9...Qh4+??

This doesn't help, as now Black will have his queen under attack as well - the computer suggests giving the piece back with 9...Nf6 10. e5+ Kc6.

10.g3 Qh6 11.Qd5+ Ke7 12.Qxc5+ Kd8?? 


The superior 12...Qd6 is assessed as, surprisingly, +3.4 points for White, according to the Lichess Stockfish analysis feature - it seems to regard White's Jerome pawns here quite highly!

13.Qf8 checkmate

Jerome Gambit: It's Not Automatic

The following game has another example of an "automatic" pawn capture that would have benefitted from a bit more reflection before appearing on the board - but, playing at one minute a game, with no increment, there is a limit to the amount of reflection that is available.

9.Qe3 Nf6 10.O-O 

White played Nc3 first, in angelcamina - JsFlexWay, 1 0 bullet, lichess.org, 2018 (1-0, 19).

10...Ng4

"Amazing how popular this move is" - Cliff Hardy.

11.Qf3+ Qf6

A bit stronger than 11...Nf6, as in angelcamina - Kvngmicky, 1 0 bullet, lichess.org, 2019, (1-0, 38).

12.Qg3 Kf7 13.h3 N4e5 14.f4 Nc6


15.e5

Excellent bullet psychology. This is not the strongest move in the position, but if Black automatically captures the pawn, he is busted.

15...dxe5 16.fxe5 Ngxe5 17.Rxf6+ gxf6



White has a Queen and a pawn for a Rook and Knight. More importantly, Black appears to be shaken.

18.d4 Nc4 

White finishes up after this, by placing his focus on the enemy King.

Jerome Gambit: The Creeping Terror

The latest Jerome Gambit game from Cliff Hardy is a doozy. Cliff takes the white pieces and appears to give his opponent "Jerome Gambit odds". His higher-rated opponent, however, returns the favor with "Berserk" odds.

As Mr. Hardy quickly demonstrates, there is much to be said for knowing the basic Jerome strategy and tactics when the time control is "think fast!" The play with the heavy pieces at the end is quite instructive.

Notes are by Cliff Hardy. Diagrams are by me.


The following game was played in a tournament on Lichess. I must say it wasn't a totally fair game though: in Lichess tournaments, you have the option of pressing the "Berserk" button at the start of the game, which shortens your total clock time by 50%. IM Eric Rosen did this so he actually had only 2 and a half minutes for the game, while I had a whole 5 minutes.

Cliff Hardy (2105) - IM Eric Rosen (2297), 
Lichess, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?! -+


6...Kf8 -++

7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 10.0-0 Qe7 11.Nc3 Bd7?! =+


Attempting to artificially castle with the standard 11...Kf7 -+ would have been better.

12.f4 Bc6 13.f5 Ne5 14.Qg3?


Oops! I left the e-pawn unguarded so 14.d3 += instead would have been better!

14...Nf7? =+

14...Bxe4 -++

15.d3 h6?! =

Weakening the pawns in front of the king is not advisable; 15...Re8 =+ would have been a superior move here.

16.Bd2 Qe5 17.Qh3 Re8 18.Rae1 b5



19.Kh1 b4 20.Nd1 Kg8? 


Lol, another oops! Black leaves his b-pawn on but I missed that I could take it. Defending it with 20...a5 would have been best.

21.c3? Qa5 22.cxb4 Qxa2 23.Bc3 Ng5 24.Qh4 Kh7 25.Ne3 Re7 26.Ng4

26...Nxg4? ++-

White's kingside pawns will now savage Black in the usual Jerome style; whereas 26...Rf8 += would have defended much better.

27.Qxg4

Black is in huge trouble, as White intends to play 28.h4 and if Black then were to save the knight with 28...Nf7??, he would wander into 29.Qxg7 mate.

27...Rg8 28.h4 Nf7 29.Qg6+ Kh8


Black has successfully defended against Qxg7 mate, but now White's f-pawn is set to cause trouble by crawling down the board like a creeping terror.

[A while back, Cliff and I discussed so-bad-they're-almost-good movies. I expressed my support for Ed Wood's "Plan 9 from Outer Space" (1959). Cliff mentioned "The Creeping Terror" (1964). Neither is likely to improve one's chess play, but they may explain why we both like the Jerome Gambit. - Rick]

30.f6 Ne5

There was no adequate defence to both of White's threats of fxe7 and fxg7+.

31.Bxe5 Rxe5 32.fxg7+ Rxg7 33.Rf8+ Qg8


Unfortunately, 33...Rg8? would have lost to 34.Qxh6 mate.

34.Qxh6+ Rh7 35.Qf6+ Rg7 36.Re3 Re8 37.Rxg8+ Rxg8



38.g3 Kh7 39.Rf3 Bd7 40.h5 Bg4 41.Rf4 Bxh5 42.Rh4 Rg5 43.Qf7+ Kh6 44.Qf6+

44...R8g6??

Black makes it easy for me. As I was moving back and forth, I clearly couldn't work out how to win this position, even with the overwhelming advantage that I had. The IM perhaps saw that  44...R5g6?? would have lost to 45.Rxh5+! Kxh5 46.Qh4 mate and probably he was still hoping to win and didn't want to let me repeat for a draw with 44...Kh7 45.Qf7+, although there the superior 45.g4! R8g6 46.Qf7+ and then 47.Rxh5+ instead would have been crushing.

45.Qh8 mate

Jerome Gambit: The Madness Continues

So, the latest game I received from Cliff Hardy, who has been specializing in tortured Jerome Gambit games, is a 1-minute (no increment) bullet game on the website lichess.org - against an International Master.

Of course.

In a game where each player had about one second per move to think, things quickly became exciting. 

Notes by Cliff. [A few by me - Rick] Diagrams by me.

Cliff Hardy - IM Pavel Sevostianov
1 0 bullet, Lichess, 2018 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4....Kxf7 5.Nxe5+ 

In another bullet game recently on Lichess, I forgot this was the move to play, got confused and played 5.Ng5+?? here instead but got justifiably destroyed in short order. I'm glad I didn't make that mistake in this rare chance to play the Jerome against an IM, where I was at least hoping to put up a half-decent game and not waste the opportunity.

5...Nxe5 6.Qh5+ Ng6 

[Interesting - is the IM unfamiliar with the various Jerome Gambit refutations, or does he figure that this will be good enough? It turns out that his "second best" moves are still pretty good. - Rick ]

7.Qd5+ Kf8 8.Qxc5+ Qe7 9.Qe3 Nf6 10.Nc3 c6 


10...d5! -+ would have been the best move here, according to Stockfish, as Black should eventually be able to get the pawn back on d5 (if White were to take it), though it may then take Black a few moves of development first before he could get into a position to win it back.

11.f4? 

Which pawn to push? 11.d4 =+ would have been much better, it turns out.

11...d6? =+ 

Pushing the d-pawn further again with 11...d5! -++ would have been more aggressive.

12.O-O Kf7

13.d3?! -+ 

13.f5 Ne5 14.d4 =+ would have been a better and feistier way to play it for White. 

13...Re8 14.f5 Ne5 15.h3 Kg8 16.Bd2 d5 17.Rae1 dxe4?


Surprisingly, quite an error - 17...Qd6 -+ would have been a better move. 

18.dxe4??

18.Nxe4! +- would have been stronger, when White's threat of Nxf6+ and then attacking the pinned knight on e5 with d4 or Bc3 would have been surprisingly difficult to diffuse e.g. 18...Bd7 19.Nxf6+ Qxf6 (19...gxf6 20. d4 ++-) 20.Bc3 +-.

18...Nc4 19.Qd3 Nxd2 -++ 

19...Nxb2 -++ would also have been good.

20.Qxd2 Bd7 

21.Qf4 Qc5+ 22.Kh1 Qe5 23.Qf3 Re7 -++ 


OK, I'm getting crushed like a bug - but I've still got my Jerome pawns... [And then, there's that clock thingy - Rick]

24.g4 Rae8?? 25.Re2?? 

All right, not the best move - 25.g5! += and the black knight would have been trapped. 

25...h6 26.h4 Nh7 27.Qg2 b6 28.g5 hxg5 29.hxg5 Bc8?

Black appears to be struggling for ideas, despite his material advantage - 29...g6! -++ (intending 30.fxg6 Nxg5) was a brilliant defence to White's pawn onslaught that the computer found. 

30.f6 Rc7 31.f7+

OK, now I'm back in the game, though Stockfish found another surprising resource here in 31.Rf5!?, since 31...Bxf5?? (31...Qd4 32.f7+ = would have been similar to the game) would walk into trouble on the e-file after 32.exf5 +-. 

31...Rxf7 32.Rxf7 Kxf7 33.g6+ Kg8 34. gxh7+ Kh8! 


Black can probably take the h-pawn any time he wants and, by playing this way, keeps more options open by not allowing White to play the queen swap with 34...Kxh7 35.Qh2+.

35.Qh2 Bg4? 

...Though he allows the queen swap now anyway... - keeping the queens on with 35...Qg5 -+ would have been more attacking.

36.Rg2?? 

The last straw for White - 36.Qxe5 Rxe5 37.Re3 would have been about equal.

[White still can win if he stays alive - regardless of the material disadvantage - long enough for Black's flag to fall. He almost makes it. - Rick]

36...Bf3 37.Kg1 Bxg2 38.Qxg2 Re6 39.Kf2 Rf6+ 40.Ke2 Rh6 41.a3 Rh2 42.Kf3 Rxg2 43.Kxg2 Qg5+ 44.Kf3 Qf6+ 45.Ke2 Qg6 46.Ke3 Qh5 47.Ne2 Kxh7 48.Nf4 Qh6 49.Kf3 Qh4 50.Ke3 Qg5 

Not that it matters, but better would have been 50...Qg3+! 

51.c3 Qf6 52.Kf3 Qe5 53.Ke3 g5 54.Nh3 Qh2 

Again, better would have been 54...Qg3+! 

55.Nf2 Qg3+ 56.Ke2 g4 and Black won on time. 


(White had 1.6 seconds left on his clock when Black lost on time).
