Jerome Gambit: Think About It - When You Can

Here is the latest "Cliff Hardy" Jerome Gambit game, another 1-minute wonder.

Notes are by "Cliff" (with diagrams and an occasional addition by me - Rick).

Do not be distressed by "Cliff's" objective, if sometimes gloomy, appraisal of White's position. It is important to understand what he was thinking - and what he was missing.

As the time limit for a game shrinks, strong players move closer and closer to choosing their moves mostly by intuition - and then supporting them through analysis - when there is time. What follows is another lesson in the application and limits of intuition.

This was a fun game.

Cliff Hardy (2111) - NN (1988), 1 0, Lichess, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?!


What is the popularity like of this move in your database/s again, Rick? I face it a lot in this particular position - it feels like maybe 75% of the time that I have this position, I encounter the move 6...Ng6.

(I just checked with The Database, in games starting 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+
6...Ng6 shows up in 46% of the games;
6...Ke6 appears in 25% of the games;
6...Kf8 is played in 15% of the games; and 
6...g6 is played in 12% of the games.
I guess many defenders see 6...Ng6 as a common sense move - block the check, save a piece, say goodbye to the other piece because White must know what he is doing & therefore "must" get a piece back, as no real opening lets White sac 2 pieces...-Rick)

7.Qd5+ Kf8 8.Qxc5 d6 9.Qe3 Nf6 10.0-0 Qe7


(This is a small improvement for Black over earlier defenses Cliff has faced: 10...Ke7 in Hardy - NN, Italian Game Bullet Arena, lichess.org, 2018 [1-0, 37]; and 10...Ng4 in Hardy - NN, 3 0 blitz, Chess.com, 2017 [1-0, 19] and Hardy - Pomo12, 10 0 blindfold, lichess.org, 2018 [0-1, 67] - Rick)

11.Nc3 c6?! =+

This looks OK to me, but not to the Stockfish computer program and when I encounter real top eschelon players in the Jerome, they find stronger moves like 11...Kf7! -+ (aiming for 12...Re8, with quick pressure against the white centre) against me, even in lightning games.

12.f4 Bd7? +-

Another move which fails to pressure white's position - 11...b5 would have maintained equality.

13. f5? Ne5 =+

I have a lot of trouble in these Jerome positions figuring out whether to play f5 first or d4 first and then f5 and here again I chose the wrong way - 13. d4 +- would have been very good for White.

14. d4 Nf7!

Holds the Jerome pawns up well.

(The lesser 14...Nc4 was seen in Hardy - NN, 1 0 blitz, lichess.org, 2018 [1-0, 20] - Rick)

15.Qf3? -++

Quickly developing with 15.Bd2 Rae8 16.Rae1 =+ would've been better.

15...Re8! 16.Re1 b6? =+

Harmless - counter-attacking with 16...c5 -++ would've been better.

17.g4? -++

The less committal 17.Bf4 =+ would've been safer.

17...h618.h4 c5! 19.g5 hxg5 20.hxg5 Nh5 21.Nd5 Qd8


22.g6? Nh6??

It was fun for me to rain the Jerome pawns down but 22...Qh4! -++ would've shown the vulnerability of the exposed white king here.

(This is one of the interesting psychological points in the Jerome Gambit. Club players have grown up playing over attacking games and solving attacking or mating puzzles. Too often, then, in their games, defenders give the attackers the benefit of the doubt concerning their aggression - if he is attacking, there must be something to it - instead of digging in and finding defensive resources. - Rick)

23.f6??

I guess we both missed the possibility of 23.Qxh5 here - oops!

(C'mon, Cliff, it was a 1-minute game with no increment. Fast. I'm surprised your opponent didn't yell "You sank my battleship!" - Rick)

23...Nxf6 24.Bg5 Ng8 25.e5 dxe5 26.dxe5 



26...Be6?? -+

I thought I had some good pressure here but 26...Bg4! -++, intending to take on d5 with the queen, would have been a crusher.

27.exf6 gxf6?? ++-

27...Qxd5 -+ unfortunately would still have refuted my position.

28.Nxf6 Qd4+


29. Re3??

29.Kg2 ++- would have been best here.

29...Nxf6??

29...Rh3! -+ (intending tricky stuff like 30.Qf2 Nxf6 31.Rxh3 Qxf2+ 32.Kxf2 Ne4+! 33.Kg1 Bxh3) was a hard-to-see win for Black.

30.Bxf6 Qxf6??

Sacrificing the queen with 30...Qxe3+ was losing, but was Black's only chance to keep the game going on for much longer.

31.Qxf6+ Kg8 32.Rxe6 Rf8 33.Re8! and Black lost on time


However, White had a checkmate coming here with Rxf8, Qxf8 or Qf7, so Black was dead anyway.

I had another couple of games against this opponent after this one. Unfortunately, the next game in which he was black, he didn't chance playing against the Jerome Gambit and played the French Defence instead.

Another Cliff Hardy / Jerome Gambit Adventure


Here we have another "Cliff Hardy" adventure, taking place a mere 3 hours after the previous one, against the same opponent.

Again, Cliff plays the Jerome Gambit in a 10 minute game -  playing blindfold!

Like any private eye story, first our hero gets into a whole lot of trouble. How he gets out is part of the adventure.

Notes are by Cliff. I have added diagrams and an occasional comment in blue.

Hardy, Cliff - Pomo12
10 0, white playing blindfold
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+ d6 9.Qe3 Nf6 



10.O-O Qe7 

Black varies from his plan in their previous game, which had seen 10...Ng4 and an eventual exchange of Queens. - Rick

11.Nc3 c6?!

The position is approximately equal. After 11...Kf7 black would have had a slight advantage. 

12.d4?!  

=/+ ; 12.f4was more accurate. 

12...Ng4?!  

+/= ; 12...Kf7 was better again 

"Amazing how popular this move is" was Cliff's comment in an earlier game. - Rick

13.Qg3?!  

= ; 13.Qd3! +/= would have been better 

13...Nf6 14.Bg5 h6?!

+/= ; 14...Kg8 = would have been less weakening 

15.Bxf6?! 

= ; 15.Bd2! Nxe4 16.Qxg6 Nxd2 17.Rfe1  +- when white's initiative is well worth the sacificed material 

15...Qxf6 16.Kh1?

The point of this lame move was that I intended to play 17.f4 without allowing 17...Qxd4+ but 17.Rad1, defending the d-pawn, would have made more sense, with black then having only a slight advantage.

Cliff continues to be hard on himself. Remember: he was playing this 10-minute game blindfold. - Rick 

16...h5? 

= ; 16...Nf4 stopping white from playing f4, with a winning advantage for black, would have been better. 

17.f4 h4 18.Qd3

With the obvious threat of 18...Nxf4?? 19.Rxf4 Qxf4 20.Rf1 with then a winning advantage for white 

18...Kg8 19.Rae1?

This ruined my position. I didn't notice that 18...Kg8 now meant that the f-pawn was under attack. 19.f5 would have been better, with an equal and interesting position. 

19...Nxf4 20.Qf3?

20.Qd2 =+  at least would have forced black to weaken his kingside with 20...g5.

20...g5?!

Inaccuracy. Best move was ...Nh5, but black still had a crushing position with the move played in the game 

21.e5 dxe5 22.dxe5 Qf5 23.g3 hxg3 24.Qxg3 Be6 25.Re4 Rh4 



-+

26.Qxh4

In a totally lost position, I attempted to seize the initiative and take advantage of black's exposed king

26...gxh4 27.Rexf4 Qh3??



After white's following move, black's queen was
trapped! Better would have been 27...Qh5 with a winning advantage for black

28.R4f3


+/= 

28...Qxf3+ 29.Rxf3 Rf8 



30.Kg2 Rd8 31.Rd3 Rf8 32.Rd6 Bc4 



32...Kf7

33.b3 Bf1+ 34.Kg1 h3?



Black's pieces now get tied up in a knot. 34...Bh3! 35.Rd1 should come out to a draw with accurate play. 

35.Ne4 Bg2 36.Nf6+ Kg7 37.Kf2 Rh8 38.Kg3 Rh6 39.Kg4 Rg6+ 40.Kf5 Kh6?! 

41.Rd7

Still winning but 41.Ng4+ Kh5 42.Rxg6 was even better 

41...Rg5+ 42.Kf4 Kg6 43.Ng4? Rf5+ 44.Kg3 Rg5 45.Rd6+ 



and black lost on time, admittedly in a lost position.

Black is helpless against a general advance of White's pawn and pieces, e.g. 45...Kf7 46.Kf4 Rg6 47.Nh6+ Kg7 48.Nf5+ Kf7 49.Rd7+ Kf8 50.Rxb7 Bd5 51.c4 Be6 52.Nd4 Rg4+ 53.Ke3 Rg6 54.Nxc6 etc. - Rick

A Cliff Hardy / Jerome Gambit Adventure: Out of Sight, Into Mind

It's time for another "Cliff Hardy" adventure!

I think Readers will admit that it takes a certain amount of courage to play the Jerome Gambit.

Playing the Jerome in a 10 minute game takes nerves of steel.

But - Playing a 10 0 Jerome Gambit game, blindfold??

I recently received three new Hardy Jerome Gambits. Like in any good private eye story, at first the hero takes it on the chin...

Notes are by Cliff. I have added diagrams and an occasional comment in blue.

Hardy, Cliff - Pomo12
10 0, white playing blindfold
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+ d6 9.Qe3 Nf6 



10.O-O Ng4

"Amazing how popular this move is" was Cliff's comment in an earlier game. - Rick

11.Qg3 Qh4

Exchanging queens would seem to make the blindfold player's calculation task easier, but perhaps black chose the line simply because he saw it as best. - Rick.

12.Qxh4 Nxh4 13.f4 Ng6



Leaves black with a slight advantage.

An improvement over 13...Ke7?!, seen in Hardy,C - NN, FICS, 2017 (1-0, 19), with a roughly even game. - Rick

14.d4 h5 15.Nc3 c6 16.f5 Ne7 17.Bf4 d5 



18.h3 Nf6 19.e5 Ne4 20.Nxe4 dxe4 21.e6 



The "Jerome pawn" at e6 blocks the light-squared bishop, which in turn blocks the rook. White seems to have compensation for his sacrificed piece. - Rick

21...Nd5 22.Bd6+ Ke8 23.Rae1 Nf6 24.Be5?!



White has some good pressure, and after 24.c4 white has a slight edge, Stockfish, but I chose (incorrectly) to capture on f6, in order to win the pawn on e4.

24...Ke7 25.Bxf6+? gxf6 26.Rxe4



26...b6 27.c4 a5 28.Rc1 Bb7 29.b3 Rac8 30.a3 Rcg8 



Black's bishop and queenside rook have taken up more aggressive positions. - Rick

31.Rc3 Rg5 32.d5 

For better or for worse, white needed to try 32.g4. - Rick 

32...Rxf5 33.d6+ Kxd6 34.Rd3+ Kc7 35.Rd7+ Kc8 36.Rf7 c5 



37.e7 Re8 38.Re6 Re5 39.Rfxf6 Rxe6 40.Rxe6 Kc7 



41.Kf2 Bc6 42.Kg3 Kd7 43.Rg6 Rxe7 44.Kh4 Rh7 45.Rg5 Kc7 46.g3 Be8 

White's best chance now rests with his opponent's ticking clock, and he hangs in, battling all the way - but this time the opposition is going to get away. - Rick

47.Re5 Kd7 48.Kg5 Rg7+ 49.Kf4 Rf7+ 50.Ke3 Re7 51.Kf4 Rxe5 52.Kxe5 Ke7 53.Kd5 Kd7 54.g4 hxg4 55.hxg4 Bg6 



56.b4 cxb4 57.axb4 a4 58.c5 a3 59.c6+ Kc7 60.Ke6 a2 61.Kf6 Be4 62.Ke5 Bxc6 63.g5 a1=Q+ 64.Kf4 Qg7 65.Ke3 Kd6 66.Kf2 Ke5 67.Kg3 Qxg5+ Black won on time
