Jerome Gambit: Quick Lesson

The latest Jerome Gambit from Cliff Hardy is a 1 0 lightning wonder. Pay attention to his notes, below - look how much information can be packed in a game that averaged less than 2 seconds a move!

Amazing.

Cliff is pretty hard on himself and his opponent, given the time control, but it only shows how challenging the Jerome Gambit can be.

1.e4 e5 2.Nf3 Nc6 3.Bc4


Forced starting position.

3...Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?! 



6...Kf8 would have been better. 

7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 



10.O-O Ke7? =/+ 

10...Kf7 would have been a better way to artificially castle. 

11.f4 Rf8?  +/=

11...Re8 =/+ would have been a more consistent move to enable artificial castling after a later ...Kf8

12.d4?! =/+ 

Seizing space by pushing the kingside Jerome pawns immediately with 12.f5 Ne5 13.d4 +/= would have been better. 

12...Kf7 13.Nc3? -+

Again, seizing space by 13.f5 = would have been better. 

13...Kg8 14.f5 Ne7 15.Qg3? -+



White thereby curtailed his own ability to push the Jerome pawns since if White were to continue after this move to push the e-pawn to e5, Black may respond with the tricky intermezzo ...Nxf5!, attacking the queen on g3; 15.Qf3 -+ would have been better.

15...Kh8? =/+

Best would have been 15...d5! 16.e5 Nxf5 17.Rxf5 Bxf5 since then 18.exf6 Qxf6 -+ would have left Black a comfortable exchange ahead. 

16.Bg5 c6 17.e5?

Over zealous. 17.Rae1 =/+ would have been better.

17...dxe5 18.dxe5 Nfd5??  

18...Nxf5 19.Rxf5 Bxf5 20.exf6 Qd4+! -+ or 20...gxf6 -+ would have been much better. 

19.f6??

As Black's knight on d5 defends the square f6, the best continuation here would have been to eliminate it with 19.Nxd5 cxd5 20.f6 +-
when Black couldn't have adequately saved his knight on e7 with ...Ng6 due to 21.fxg7+ Kxg7 22.Bxd8.

19...gxf6 20.Bxf6+? -+

After 20.exf6 = or 20.Nxd5 fxg5 21.Rxf8+ Qxf8 22.Nc7 $5 Rb8 23.e6 = White would have had compensation for the material deficit, due to his cramping advanced Jerome pawn. 

20...Nxf6 21.exf6 Ng6 22.Rad1 Qb6+ 23.Kh1 Be6 24.Rd6? 



24.b3 or 24.h4 would have been better tries. 

24...Bf7?! -+

24...Bc4 -+ would have been more attacking. 

25.Ne4 Rad8? =/+

The greedy 25...Qxb2 26.Ng5 Qe5! -+ would have been much better. 

26.Ng5?? -+ 

26.Qh3! Rxd6 27.Nxd6 would have put Black under a bit of pressure, with the threat of Qh3-h6-g7 mate, though ...Qc7! would then still have left Black with a slight advantage. 

26...Rxd6 27.Qxd6 Qxb2?? = 



27...Kg8! or 27...Qe3! in either case with a winning position for Black, were better.

28.h4?? -+ 

Stockfish found the interesting 28.Qxf8+! Nxf8 29.Nxf7+ Kg8 30.Nh6+ with a draw by perpetual check, but I decided to play for the win (mind you, I didn't find this line myself during the game anyway so couldn't have played even it if I'd wanted to?) 

28...Kg8! 29.h5 Nh4?? +- 

Black had 2 good moves here, the smart fork 29...Qb5! or the safe 29...Qe5! - in either case he'd have then had a winning position. 

30.Nxf7 Rxf7 31.Qd8+ Rf8 32.f7+ Kg7 33.Qg5+?? =/+


Surprisingly a blunder, as Black could now have restored material parity and gotten his king safe; 33.h6+ Kg6 34.Qxf8 or 33.Qxh4 both would have left white with an easily won position. 

33...Kh8?? 

The final blunder; instead, after 33...Ng6 34.hxg6 hxg6 =/+ White would have been fortunate enough if he went on to hang in for a draw.

34.Qxh4 Qg7 35.h6 Qg6? 

Though 35...Qe5 36.Re1 Qd6 37.Qg5 Qd4 38.Qe7 +- still would have won for White, or 35...Qc3 36.Qe7 +- 

36.Qd4+ Qg7 37.Qxg7 checkmate
