Jerome Gambit Ending: It's Drawn, Unless It Isn't (Part 2)

16...Rf8 17.Qh4 Bd7 18.Bg5 Qf7

Black moves his heavy pieces to the f-file.

I was not too concerned. I had no plans to open either the e- or the f-file. I planned the usual pressure on f6 while I waited.

19.a3 c5 

Here comes some of the pressure against White's center. I think my opponent would do better to keep things dynamic, however, rather than exchange pawns, as he does on the next move.

20.Rad1 cxd4 21.Rxd4 Bc6

If Black is thinking about moving into an endgame with Bishops-of-opposite-colors, then he is probably not worried about dropping a pawn. Such endings are notoriously drawish, even with a difference of 1, 2, or even (sometimes) 3 pawns. Still, I thought I had learned enough about them to prevail.

22.Rxd6 Rad8

This move overlooks something. Stockfish 7, after the game, suggested that 22...Nd7 led to an equal game.

23.Rxd8 Rxd8 24.e5

Yes.

24...Re8 25.exf6 Rxe1+ 26.Qxe1 gxf6 27.Bh4 Qg6

28.Qg3 

Giving my opponent what he apparently wants - with Queens off of the board we will have a "safe" endgame.

I was getting dizzy trying to analyze the many things his Queen and my Queen could do in this position, so I finally decided to take them off of the board.

28...f5

A bit of humor here - who will be the one to swap Queens? I think the sharper choice was 28...Kf7, as 29.Qc7+ would have been too crazy for me, and 29. Qxg6+ hxg6 is one step closer to splitting the point. Also, advancing the pawn, this move and next, puts it at risk. The way things are, Black might be able to afford being 2 pawns down, but probably not 3.

29.b3 f4 30.Qxg6+

I can't remember why I didn't play 30.Qxf4, but I guess it was to avoid 30...Qb1+, etc. The f-pawn will fall, anyhow.

30...hxg6

White will soon be 3 pawns ahead. Will it be enough? I think so.

31.Bg5 Bd5 32.c4 Be6 33.Kf2 Kg7 34.Bxf4 Kf6 

Black's defense will be based upon putting his pawns on the same colored squares as his Bishop, and then constructing a blockade of White's advancing pawns.

35.Bc7 b5 36.cxb5 Bxb3 37.Ke3 Ke6

For now, Black's b-pawn will hold off White's two Queenside pawns. However, some time in the future - when White's pawns have advanced to a5 and b6 - he will have to guard against the sacrifice a5-a6 which will let the b-pawn advance toward promotion.

In the meantime, White will create two passed pawns on the Kingside. It will be difficult for Black's Bishop to guard against threats on both sides of the board.

38.Kf4 Kd5 

Going after White's a-pawn, but the King needed to stay and play defense on the Kingside.

39.h4 Kc5 40.b6 Bc4 41.Ke5 

Black's King will not be able to get back to the Kingside in time, now. White will create a passed pawn that will cost Black his Bishop - and then the game.

41...Bf1 42.g4 Be2 43.h5 gxh5 44.gxh5 Bd3 

45.h6 Kb5 46.Kf6 Bh7 47.Kg7 Bf5 48.h7 Bxh7 49.Kxh7 Ka4 50.f4 Kxa3 Black resigned

The extra pawn will promote.

Jerome Gambit Ending: It's Drawn, Unless It Isn't (Part 1)

                                                                     

I won my last Jerome Gambit in the current Chess.com Giuoco Piano Thematic Tournament, so it is time, again, for me to sit and wait and see who catches or bypasses me.

In the meantime, it is fun to share the game, as it required some strategic re-thinking on my part, as well as a pleasant return to some endgame understanding that I acquired about 35 years ago, from a match game I played against my boss.

Giuoco Piano Thematic Tournament,  Chess.com, 2016

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

The Giuoco Piano Thematic Tournament is a 10-player, double round robin, which means that I had 9 chances to play the Jerome Gambit - and, as it turned out, I played 8 at the same time to start the tournament! (I had Black against keshavdmutkule first.) I finished with 4 wins, 3 wins on time, and 2 losses.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8

Ah, yes, the Jerome Defense to the Jerome Gambit - both care of Alonzo Wheeler Jerome. The defense was played successfully in two correspondence games against Daniel Jaeger in 1880.

To date my record against it is 23-6-3, which is a score of 81%, which is pretty decent.

7.Qxe5 Qe7 

Solid. Black's Queen sometimes goes to f6 in different variations, but here it finds itself a different home. I have scored 6-2-2  (70%) against this.

7...d6 was seen in perrypawnpusher - ulisimbolon, Giuoco Piano Thematic Tournament, Chess.com, 2016, (0-1, 22). (keshavdmutkule would have had to look up that game on the Chess.com website, as it wasn't posted on this blog until recently.) 

8.Qf4+ Ke8

I faced 8...Nf6 in the earlier perrypawnpusher - ERICOLSON, FICS, 2007 (1-0, 33); perrypawnpusher - frencheng, 10 5 blitz, FICS, 2010 (1/2-1/2, 31); and perrypawnpusher - jonathankochems, FICS, 2010 (1-0, 39).

The text move strikes me as a bit unusual, and it highlights one of Black's challenges in the Jerome - even if he is still better - and that is: where does his King go?

Of equal interest to me was if my opponent had found this blog, and, more specifically, my notes to my game with auswebby.   

9.O-O

I am not sure if the text is an improvement over 9.Nc3, seen in perrypawnpusher - Chesssafety, Chess.com, 2012 (1-0, 25) and perrypawnpusher - auswebby, Giuoco Piano Thematic, Chess.com, 2015 (0-1, 37), but the games could have transposed, anyway.

9...d6

More sedate and more solid than 9...Bd6 as seen in perrypawnpusher - dzetto00, Giuoco Piano Thematic, Chess.com, 2016, (1/2-1/2, 25). (Too bad. I was willing to face that line again.)

10.c3 Nf6 11.d4 Bb6 12.Re1 Kf7

Black plans to castle-by-hand on the Kingside.

13.Nd2

I am used to attacking the Black King along the e-file or f-file, or advancing the "Jerome pawns" to cause chaos in the enemy's ranks.

In this game, however, I realized that there was not likely to be any kind of bashi-bazouk attack; instead, I was going to have to adopt the patient style that I have seen in some of Bill Wall's games, where he establishes a solid pawn center and waits for his opponent to bash himself against it. After all, Black has the advantage, so, by rights, he should be the one attacking, right?

13...Re8 14.Nc4 Kg8 15.Nxb6 axb6 16.f3

Jerome Gambit: Past is Prologue

Here is a game from the first round of the Jerome Gambit tournament at RedHotPawn.com. Both White and Black clearly have a grasp of the opening, and the battle is an entertaining one. The outcome is an indication of how the second round - and the tournament - will turn out.

10.hxg4 Nh6

Reasonable and straight-forward, especially since White's response "forces" Black to make a move he wants to make, anyhow; but 10...d6 was deeper and better. 

11.g5 Ng4  

Of course. Still, taking the g-pawn was better, as now the game has equalized - although that may not be apparent at first glance. 

12.Qf3+ Ke8 13.Qh3 Bxg5 14.Bxg5 Qxg5 15.Nc3 d5

15...h5!? was a thematic alternative. 

16.f4 Qg6

Thinking "attack" when "defense" was better attended to by 16...Qd8. 

17.Nxd5 Kd7 18.f5 Qg5 19.e6+ Kc6 

The alternative 19...Ke8 20.Rae1 is pretty bad for Black, but everything else leads to mate. 

20.Qc3+ Kxd5 21.Qc5+ Ke4 22.Rae1+ Ne3 23.Qe5 checkmate

Jerome Gambit: Finish Him Off

The following position arose in the recent 1-minute Jerome Gambit game xjjettx-ViswanathanAdam04 at lichess.org. (I still can not wrap my head around the idea of playing the Jerome Gambit in bullet chess.)

It is White to make his 47th move. What is his quickest win? Remember, since it is a 60-second game, so if White has spent a second on each move played so far, he has only 14 seconds left to complete the game, so it is time to think fast.

If you saw 47.Rc8 (or 47.Rc7) followed by 48.Rh8 (or 48.Rh7) checkmate, good for you!

Instead, White played 47.Rf6, which allows the saving 47...R-any
freeing up the c-pawn to advance and Queen.

White was not the only player in time trouble, however, and after 47...Kh4 48.Rxg6 Black surrendered a pawn, allowing White hope to promote, as well.

That proved unnecessary, however, as after 48...Rf1 White checkmated, after all, with 49.Rh6.

So much of bullet chess is rapid assessment - and rapid moving - and in this case it was useful to visualize: 

Black un-blocking his c-pawn with a Rook move that checked White's King, gaining the needed tempo to promote (that is why White had moved his King to the protected square f4 just before we joined the game);

White's King and pawn hemming in Black's King, allowing for his Rook to achieve reaching the 8th rank followed by checkmating on the h-file; 

Later, Black un-blocking his c-pawn by moving his Rook anywhere (checking the enemy King was no longer necessary, as White's Rook had left the c-file); and

White realizing that the position had changed, and changed again, so that Black's King was again hemmed in, and checkmate was available.

   

Jerome Gambit: One More Mystery Game

While I am still a bit surprised that I overlooked posting one Jerome Gambit loss from my ongoing Chess.com tournament (see the previous "Jerome Gambit: Very Serious Business") the fact that I also did not share the following game is less of a mystery: I got outplayed in a line that I really don't have a fix for. If an opponent in the tournament wanted to look up the game, that was one thing; but I was not ready to share my gloom and doom (and ideas) on this blog, as a "suggestion" of what to play. (As I have written before, I share a whole lot, but  not everything here.)

7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qxe5+

I have scored 11 -1 with the alternative 10.Qf3. Alonzo Wheeler Jerome was  3 - 2 with one incomplete game. 

10...Kxe5

11.b4 Bd4 

11...Bb6 was seen in perrypawnpusher - djdave28, Chess.com Italian Game Tournament, 2014 (1-0, 22).

12.c3 Bb6 13.d4+ Ke6 

Prudent. The risks of 13...Kxe4 were shown in perrypawnpusher - djdave28, Italian Game tourney, Chess.com, 2015 (1-0, 32).

White will have to work hard to make something of his position, or he will find himself missing the power of his Queen.

As the game went, I was outplayed by my opponent.

14.O-O Nf6 15.Nd2 d6 16.Bb2 Bd7 17.Rae1 Be8 

18.e5 dxe5 19.Rxe5+ Kd7 20.Rfe1 Rd8 21.Nc4 Bg6 22.Nxb6+ axb6 23.Re7+ Kc8 24.Rxg7 Rd7 25.Ree7 Rxe7 26.Rxe7 Re8 27.Rxe8+ Nxe8 

White has two pawns for his sacrificed piece, and perhaps that might be enough to split the point against a weaker opponent, or in a blitz game; but not in this game.

28.Kf2 Kd7 29.Ke3 Ke6 30.c4 Nd6 31.d5+ Kd7 32.Kd4 Nf5+ 33.Ke5 Ne3 34.Kd4 Nxg2 

35.c5

Instead, Stockfish 7 after the game recommended 35.Bc1 Bb1 36.a4 Nh4 37.c5 Nf5+ 38.Ke5 bxc5 39.bxc5 Ne7 40.Bg5 Ba2 41.Bxe7 Kxe7 42.a5 Bc4 43.Kd4 Bf1 44.Ke5 Kd7 45.Kd4 Be2 46.Ke3 Bc4 47.Kd4 Bf1 48.Ke5 Ba6 49.Kd4 Ke7 50.Ke5 Be2 and although Black still has the advantage, it does not look like either player is making any progress.

35...b5 36.Bc1 Nh4 37.Bf4 Nf5+ 38.Ke5 Ne7 39.a3 Bf7 

40.d6

After the game Stockfish 7 took issue with this, suggesting a line that is not quite so much better for Black: 40.c6+ bxc6 41.dxc6+ Kxc6 42.Ke4 Bg6+ 43.Ke5 Nc8 44.Kd4 Nd6 45.Bg5 Bb1 46.Bd8 Ne4 47.Ke3 Kd7 48.Bh4 Nd6 49.Kd2 Kc6 50.Bd8 Nf7 51.Bh4 Bg6 52.Kc3 Kd5 53.Kb3 Nd6 54.Kc3 Bf7 55.Bd8 c6

40...cxd6+ 41.cxd6 Nd5 42.Bd2 Nb6 43.Bc1 Nc4+ 44.Ke4 Kxd6 45.Kd4 Kc6 46.Ke4 Bg6+ 47.Kd4 Nd6 48.Bf4 Nc4 49.Bc1 h5 50.h4 b6 51.Kc3 Kd5 White resigned

Whew! I am reminded of the silly phrase "trampled to death by a herd of turtles." Nice work by my opponent!

Jerome Gambit: Very Serious Business

In the current Giuoco Piano thematic tournament at Chess.com I am in first place (although this may change) and my only chance to finish on the top of the field is to win my last Jerome Gambit game - which is in the endgame stage. So far, I have 3 wins, 3 wins on time, and 2 losses with the Jerome.

I was surprised to find that I had not presented on this blog the following game with the Jerome Gambit, from the same tournament. In part this may be due to the fact that my opponent forfeited a significant number of his games - but not before he had won a full point from me. If only I had lost slower!

After the game Stockfish 7 recommended a line that shows how complicated the game is, but which would lead to only an edge for Black: 15.h3 b4 16.Nd1 Qf7 17.a3 bxa3 18.Rxa3 Bd7 19.Qe1 Re8 20.c4 Nf6 21.Bh4 Kg8 22.Bf2 Bb6 23.b4 c5 24.bxc5 dxc5 25.Bh4 Bc6 26.Nc3 Qd7 27.Qe3 a5 28.e5 a4 This kind of play is above my head.

15...Bxb2 16.Rab1 Bf6 17.d4

After the game Stockfish 7 was critical of this move, but its suggested play - giving up a pawn (eventually the exchange), allowing a passed pawn on the Queenside, opening up the h-file for Black's Rook against my King - looks like a fever dream (although it claims Black is only 3/4 of a pawn ahead at the end): 17.h3 Bxa2 18.Rbe1 Bb2 19.hxg4 hxg4+ 20.Kg1 a5 21.f5 a4 22.Qxg4 a3 23.Qf3 Re8 24.Be3 b4 25.Nf4 Kg8 26.g4 Bc3 27.Re2 Bf7 28.g5 a2 29.g6 a1=Q 30.Rxa1 Bxa1 31.gxf7+ Qxf7 32.Ng6 Rh7. Whew!

17...Bxa2 18.Rbe1 Bc4 19.e5 Bxg5 20.fxg5+ Kg8 21.Qf3 

I wish I could say that I had seen Stockfish 7's recommendation, and merely rejected it, but I had no idea: 21.h3 a5 22.Kg1 dxe5 23.hxg4 hxg4 24.dxe5 a4 25.Rf4 a3 26.Nd4 a2 27 Ra1 Qe8 28.e6 Bxe6 29.Nxe6 Qxe6 30.Qb3 Qxb3 31.cxb3 g3 32.Rf3 Kh7 33.Rxg3 Rhe8 34.Kf2 Kg6 35.Rc3 Re7 36.Rc6+ Kxg5. The computer sees Black as up 2 3/4 pawns. 

21...Re8 22.g6 dxe5 White resigned

I had been looking at 23.Qf7+ here, "winning" a Rook, when I suddenly realized that the f7 square was protected by Black's light-squared Bishop. Discouraged, and down a piece and a  pawn, I gave the game up.
