No Way to Make A Living


Using my "extra" pawns to chase down a draw or a win against Black's extra piece in the Jerome Gambit can sometimes be an exhausting task. "That's no way to make a living," as they say. Even if your opponent slips at the end...

perrypawnpusher  - vladchess
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Kf8

One way to change the flow of the game and try to keep his King out of trouble.

6.Nxc6 dxc6 7.O-O


I've had success after 7.d3 Qf6 8.O-O in two games in which I reversed my 7th and 8th moves:  perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 29) and perrypawnpusher - Lark, blitz, FICS, 2011 (1-0, 12).

7...Nf6

Also seen: 7... Bd6 perrypawnpusher - Lark, blitz, FICS, 2009 (1-0, 18) and 7... Be6, perrypawnpusher - CorH, blitz, FICS, 2009 (0-1, 74).

8.d3 h6

8...Bg4 was seen in Lowe - Parker, corr, 1879, (1-0, 37)

9.Be3 Qe7

Exchanging Bishops was also okay.

10.d4 Bb6 11.f3 Kg8


Computers like Rybka tend to like solid pawn centers like the one White has and rate it accordingly, but there is a lot to do to get "something" out of the position for White.

12.Nc3

Moving another pawn with 12.c4 might have been better, at least according to Houdini 1.5a.

12... Kh7

The cute 12...Nd5 (note the pin on the e-pawn) was a bit better.

13. Qd3 g6 14.f4

Instead, Houdini prefers 14.Na4 Ba5 15.c4 b6 16.a3 c5 17.dxc5 Rd8 18.Qc2 bxc5 19.Bxc5 Bb6 20.Qf2 Qe8 21.Nxb6 axb6 22. Be3 Qe7 23.Rfd1 Be6 24.Qc2 Nd7 25.Qc3 Qg7 26.Bd4 Qf7 when Black's advantage is minimal.

Okay, if you say so... (The next book that I review for Chessville will be a strategy book!)

14...Rg8 15.Rae1 Ng4 16.h3 Nxe3 17.Qxe3 c5 18.Nd5 Qd6 19.Nxb6 axb6

20.dxc5 bxc5 21.Rd1 Qb6 22.Qb3 Be6 23.Qxb6 cxb6

If there was a thread in this game, I've probably lost it...

My only chance is to activate my Rooks.

24.a3 c4 25.Rd6 Bc8 26.Rxb6 Re8 27.e5 c3 28.bxc3 Rxa3 29.Rb3 Ra2 30.Rf2 Re7 31.Rd2 Rf7


32.g3

Simply overlooking the loss of a pawn.

32...Bxh3 33.Rb5 Re7 34.Kf2 Bf5 35.Kf3 h5 36.Rbd5 Ra3


Black is still better, but 36...Rc7 here would have been stronger.

Time was getting short for both of us. My plan was to continue to harass Black until one of us blundered.

37.Rc5 b6 38.Rc6 Rb7 39.Kf2 b5 40.e6  Re7 41.Rd7


Going for the swindle.

41...Rxd7 42.exd7 Bxd7

Simply 42... Ra8 was Game Over.

43.Rc7 Kh6 44.Rxd7 Rxc3 45.Rd2 b4 46.Kg2 draw.


This game reminds me of the saying about airplane landings: any one that you can walk away from is a good one...

Levity

Jerome Gambit Gemeinde member Stipe Drinovac's sense of humor appears in his chess games. We have seen him finish off an opponent in a Jerome Gambit game with the move "0-0-0 checkmate" (see "Could Not Happen" Part 1 & Part 2). In the position below, he says "goodbye" with an underpromotion.


While Black patiently broke through on the Queenside, White used a breakthrough in the center (including an upstart "Jerome pawn" – the pawn on f6 started on d2) to win back his sacrificed piece.

31.fxg7+

White has several checkmate possibilities, and they all start with this move.

31...Kg8 32.Qxh7+

Grin.

32...Kxh7 33.gxf8/N+


Smile.

33...Kg8 34.Nxe6 Black resigned


Black is down a Rook and a Knight and faces a forced checkmate.

It's just really that important




In a recent book review at Chessville that I wrote about GM Nigel Davies' 10 Great Ways to Get Better at Chess (Everyman Chess, 2010), I mentioned

For an alternate “great way” – or as an addition – Chapter Two suggests Study the Endgame. Again, Davies gives game examples from his students, but this should not be necessary to persuade readers of the truth of his suggestion: most club players unconsciously imitate the play of early chess-playing computers, memorizing opening moves, concentrating on tactics at the expense of long-term planning, and playing the endings like duffers…

Davies would have been justified in giving a Chapter Three (“Study the Endgame Some More”) and a Chapter Four (“Keep Studying the Endgame”) just to reinforce the topic. It’s just really that important.
I wish I had taken more of my own advice before playing the following game.

perrypawnpusher - BEEB
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+

A "calming variation", but still a side line to watch.

8.Kxf2 Qf6+

8...Qh4+ was played unsuccessfully in annicks - Ribosome, Dos Hermanas Internet, 2002, (1-0, 23).

9.Qxf6+ Nxf6


By returning the sacrificed piece, Black has moved play into a Queenless middlegame or early endgame where he is simply down a pawn.

He no longer faces the Bashi-Bazouk attack of the Jerome Gambit. However, he also no longer has an objectively won game.

Sometimes, chess is a strange game.

10.Nc3

I have also tried 10.d3, as in perrypawnpusher - ScudRocket, blitz, FICS, 2009 (1-0, 24)

10...Re8

Black could play 10...Rf8 as in blackburne03 - bobby-pisher, Internet Chess Club, 2003, (1-0, 23) or perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0,42); or in a delayed manner such as 10...b6 11.d3 d6 12.Rf1 Rf8 in blackburne - Bullit52, ChessWorld thematic tournament, 2007 (1-0, 32),


He also could start with 10...d6 and after 11.d4 c6 12.h3 play 12...Re8 as in brianwall - maten8, Internet Chess Club, 2004 (1-0, 21).

11.d3 d6 12.Rf1 Ng4+ 13.Kg1+ Kg7


Tactics can hide even in "boring" positions. For example, now 14.Nd5

14.h3

Laziness on my part. "The game will play itself."

The possible Knight fork at c7 remains "on" for a number of moves, despite my overlooking it.

14...Ne5 15.Be3 Be6 16.b3 c5 17.a4 a6 18.Rf2 Rf8 19.Raf1 Rxf2 20.Rxf2 Rb8 21.d4 Nd7 22.dxc5 dxc5 23.Nd5 b5


Like two zombies dancing a waltz, my opponent and I push the pieces around the board and pretend that we are playing chess...

24.axb5

If someone had whispered "Pssst. This is a middlegame" I might have looked for and found the tactical 24.Bf4 Rb7 25.Nc7 Bf7 26.Rd2 Nf6 27.Nxa6 bxa4 28.Nxc5 Rb5 29.Nxa4 Nxe4 30.Re2




analysis diagram







24...axb5 25.Nf4 Bg8 26.Nd3 c4 27.bxc4 bxc4 28.Bd4+ Kh6 29.Ne5 Rb1+ 30.Rf1 Rxf1+ 31.Kxf1 Nf6


For all of my shuffling, the e-pawn will now be lost.

32.Be3+ Kh5

My opponent has grown complacent, too, or he would have played the wiser 32...Kg7

33.c3

Readers who enjoy tactical endgames surely saw the better 33.g4+  which merely threatens checkmate after 33...Kh4 34.Kg2, costing Black his Knight.

Playing on "auto-pilot" was hurting both of us.

33...Nxe4 34.Bd4

The checkmate was still on, in a slightly longer version, with 34.g4+.

34...Ng3+ 35.Kf2 Nf5

This slip costs a piece.

36.g4+ Kh4 37.gxf5 gxf5 38.Kg2


With a piece for a pawn, White is now winning – but how exactly does he win?

If he can get his King to d4 and then attack the Black pawn at c4 a second time (with the Knight) he can win it. For that to happen, it might be best to trade White's weak h-pawn for Black's f-pawn. Then, with the help of the extra piece, White's c-pawn can be "faster" than Black's h-pawn.

38...Bd5+ 39.Kh2

Protecting the pawn for now. After the game Rybka suggested 39.Nf3+, since 39...Kh5 40.Kg3 Be4 41.h4 Bd5 42.Kf4 Be6 43.Bf2 Kg6 44.Ne5+ Kh5 45.Nc6 Bd7 46.Ne7 would allow White to win the f-pawn. If Black exchanges off the Knight instead with 39...Bxf3+ 40.Kxf3 then after 40...Kxh3 41.Kf4 White's King will wander over and win the Black c-pawn and Queen his own; the Black h-pawn will not be an issue.

39...Be6 40.Nf3+ Kh5 41.Kg3 f4+

A mistaken offer to exchange pawns that I should have accepted.

42.Kh2 Kg6 43.Kg2 Kf5 44.Ne5 Bd5+ 45.Nf3 Bg8



Black is content to sit and wait.

It is not clear to me that there is a win any more for White, as Black's advanced King and h-pawn make it dangerous for White's King to leave that area to help win the c-pawn.

My "winning try" falls to the inevitability of the Bishops-of-opposite-colors endgame.

46.Kf2 Ke4 47.Nd2+ Kd3 48.Nxc4 Kxc4 49.Kf3 Be6 50.h4 Kd5 51.Kxf4

The position is drawn now, and a dozen moves later, too.

51...Bf7 52.Kg5 Bg6 53.h5 Bd3 54.Kf6 Ke4 55.Kg7 Kf4 56.h6 Kg5 57.Bf6+ Kh5 58.Bd4 Kg5 59.Be3+ Kh5 60.c4 Bxc4 61.Kxh7 Bd3+ 62.Kg7 Kg4 63.h7 Bxh7 drawn




This game contained plenty of wasted opportunities.

Illusions

So much of chess is trusting your own plans and being skeptical of your opponent's. Yet, misperceptions arise, and our play is often guided by "illusions" of what we expect or what we fear, instead of what actually is happening (or will happen) on the board.

 
perrypawnpusher - yuriko
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Nf6 5.Nc3 Bc5 6.Bxf7+


The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4


8...Bxd4 9.Qxd4 d6 10.f4 Nc6 11.Qd3 Re8 12.Bd2 Kg8 13.Rae1 Be6

This is an improvement over our earlier game, which continued 13...Nb4, perrypawnpusher - yuriko, blitz, FICS, 2010 (1-0,31). Black's pieces are developed, his King is safe, and he has the advantage.

14.Nd5

That move. I am sure that Rybka would be proud.

14...Bxd5 15.exd5 Ne7 16.Bc3


Simply an oversight. Necessary was to protect the pawn with 16.c4. Fortunately, my opponent either overlooked the capture, or took my error as deep thought.

16...Rf8 17.Bxf6 Rxf6 18.Qe4 Rf7 19.f5


Deciding that if there is any play for White (there isn't) it has to be on the Kingside.

19...Qf8 20.Qe6 Kh8 21.g4 h5 22.h3 hxg4 23.hxg4 Re8


At first glance it looks as if White's Queen is taking on the combined forces of Black's Queen, two Rooks and Knight.

In actuality, Black's dallying pawn moves on the Kingside (instead of re-positioning his Knight to f6, via g8) have given White an even game, and Black's last move has given White a clear advantage.

24.Qe4

Giving the Queen the chance to move to the h-file with Qe4-h1, an idea that only gets partial credit. 24.g5 was the correct move, with the plan of advancing to g6 if possible, setting up a mating net that will close when White doubles rooks on the h-file.

Or at least that's what Rybka suggested after the game.

24...Kg8 25.Qe6 Kh8 26.Qe4

Toying with the idea of a draw by repetition. This was underestimating my chances.

My opponent decided not to repeat, but keeps the position balanced.

26...g6 27.Qd4+ Kg8 28.f6 Nc8



29.g5

Logical, but 29.Re6 gave White an edge.

Time was getting short for both of us.

29...Rxe1 30.Rxe1 Nb6 31.Qe4


Aiming at the pawn at g6, a major weakness in Black's King's shelter.

31...Qc8

Having been sold on the illusion of my attack for many moves, my opponent now conjures an illusion of counter-attack for himself. While objectively this move is wrong, because it allows checkmate, it turns out to be a game-saver for yuriko.

Chess is strange.

There was a likely drawn Rook + pawns vs Rook + pawns endgame after 31...Nd7 32.Qxg6+ Kh8 33.Re3 Nxf6 34.gxf6 Qg8 35.Rh3+ Rh7 36.Qxg8+ Kxg8.

32.Qxg6+ Kf8 33.Qh6+ Kg8



Now all that I had to see was 34.g6, the triumph of the "Jerome pawns" (with f6-f7+, winning a Rook, and then checkmate, following) and the game was mine.

Instead, I worried that 34.g6 could be answered by 34...Qg4+ (that was why Black had played 33...Qc8) with either counterplay, or a draw, anyway – so with little thought (time was ticking) I forced the draw myself.

34.Qg6+ Kf8 35.Qh6+ Kg8 36.Qg6+ Kf8 37.Qh6+ Kg8 drawn.

The final position was the same as in the previous diagram.

Only now add what I had missed, g5-g6 for White, and what I had feared, ...Qc8-g4+ for Black.

In response to the check White's King jumps to h2 and Black has no more checks! White's checkmate is still forced.

Unbelievable.

Nd5

This game is the latest in a series of my attempts to understand a move that Rybka has recommended in various post mortems. Although I still quite don't understand it, I played it – and my opponent responded as if he didn't understand it, either – and suddenly the game was over.

perrypawnpusher  - LeChinois
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Nf6 5.Nc3 Bc5 6.Bxf7+


The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4


8...Bxd4 9.Qxd4 Nc6

More frequently seen is 9...d6 10.f4 Nc6, but I do not see a problem with the text.

10.Qd3

I've lost a couple of games with the alternative, 10.Qc4+, e.g.: 10...Kg6 11.f4 Re8 (11...Rf8 12.f5+ Kh7 perrypawnpusher - mjmonday, blitz, FICS, 2010 (0-1, 26)) 12.f5+ Kh7 perrypawnpusher - DeDaapse, blitz, FICS, 2010 (0-1, 19)

10...Qe7


11.f4

After the game I fed the moves to Rybka in blundercheck mode, and here (and for subsequent moves) it recommended instead 11.Nd5.

I know that Nd5 is the kind of move that you play here (at least according to Rybka, which has made that recommendation several times in past games) but I did not like what would happen with Black's Queen at e7: 11...Qxe4 12.Qxe4 Nxe4 13.Nxc7 Rb8. I was hoping for more than exchanging my e-pawn for my opponent's c-pawn. 

11...d6 12.Bd2

Again, Rybka preferred 12.Nd5 Qxe4 13.Qxe4 Nxe4 14.Nxc7 Rb8.

12...Bd7 13.Rae1

Okay, with my e-pawn protected with this move, now I'm ready for Nd5.

13...a5

Of course Rybka preferred 13...Rae8 – followed by 14.Nd5 (and 15.Bc3).

14.Nd5

Tah dah!

White also had 14.e5 dxe5 15.fxe5 Nxe5 16.Qd5+ Kg6 17.Qxe5 Qxe5 18.Rxe5 which equalized, but which took much of the dynamism out of the game. 

14...Be6

Well, that settles everything...

Rybka pointed out the essential 14...Qd8 and then suggested that White could/should draw with 15.Nxf6 Qxf6 16.Bc3 Qe7 17.e5 Be8 18.Re3 Kg8 19.Qd5+ Kh7 20.Qe3+ Kg8 21.Qd5+ etc.

15.Nxe7 Black resigned

Could Not Happen, Right? (Part 2)

Not too long ago I received an email from Stipe Drinovac who had noticed (from a post at Chessgames.com) that I was interested in Jerome Gambit games.  He sent me a game that he had played last year at a club event. My eyes popped.

Drinovac - NN
club game, 2010

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


7.f4 Qf6 8.Rf1

I found only a couple dozen games in The Database with this move (White scored 54%), but the players were impressive: Jerome Gambit Gemeinde members mrjoker, Petasluk and Gary_Seven, as well as paladins Fritz 5.32, Fritz 8, Junior 7 and Zappa 1.1.

8...Nh6 9. Nc3 d6


10.Nd5 Qd8


And, just like that, White is winning, according to Rybka, which preferred the offer to exchange Queens with 10...Qf7.

11.d4 Bxd4 12. fxe5 dxe5


13.Bg5 Qg8 14.c3 Bb6 15.Nxb6 axb6


16.Qh3+ Kd6 17.Qd3+ Kc6 18.Rf8


If Black had not realized until this point that he was doomed, this probably delivered the message.

18..Qe6 19.Rxh8 b5 20.a4 bxa4 21.Re8


Another deflecting sacrifice, offering the Rook a second time.

21.Qxe8

Drinking the poison. Declining with something like 21...Qb3 left Black down the exchange, with his King still in danger. Rybka likes 22.Bd8, putting pressure on c7 and planning to sacrifice White's Bishop there, if nessary, as a response. 

22.Qc4+ Kd6 23.O-O-O checkmate

Q.E.D.
