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.

Could Not Happen, Right? (Part 1)

Many readers are familiar with the game young Paul Morphy played against his uncle, Alonzo Morphy, where he gave his elder the odds of a Rook, and still checkmated him – with the last move being Castles:

Paul Morphy - Alonzo Morphy
New Orleans, 1850
Remove White's Queen Rook

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3 Nd4 9.Bxd5+ Kd6 10.Qf7 Be6 11.Bxe6 Nxe6 12.Ne4+ Kd5 13.c4+ Kxe4 14.Qxe6 Qd4 15.Qg4+ Kd3 16.Qe2+ Kc2 17.d3+ Kxc1 18.O-O checkmate


This is certainly a fun game to play over.

What if, instead of "Rook odds", someone gave an opponent "Jerome Gambit odds" – and also won the game with Castles as the last move?

Could not happen, right?

It did happen. I'll post the game tomorrow.

The Kind of Game


If it's true that "bad things come in threes" (see "Struggling" and "Tactical Sloppiness") that would be a good explanation for the following win that I recently scored. It's the kind of game you might as well have if your opponent is going to have difficulty with the clock...



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 Bxd4 9.Qxd4 d6 10.f4 Nc6 11.Qd3 Re8 12.Bd2 Kg8 13.Rae1 Bg4


A rarely-played move (according to The Database) in a standard position. Rybka and Fritz8 almost always suggest Nc3-d5 now for White, but I was lured by the opportunity to start my Kingside pawns moving "for free". Instead, I chased the Black Bishop back to a better square.

14.h3 Be6 15.g4

Like I said in the note to move 13, better was 15.Nd5. The reason has little to do with the weakening of White's pawn structure, and more to to with dropping the c-pawn.

15...Nb4 16.Qg3 Nxc2 17.Re2


This should cost the exchange after 17...Bc4. 

17...Nd4 18.Rg2 Qd7 19.f5


I figured at this point that whatever chances I had to save the game (slim & none, actually) would lie in a Kingside attack.

19...Bc4 20.Re1 Nc2

Much better was 20...Qc6.

21.Rc1 Nd4 22.g5 hxg5 23.Bxg5 Rf8


Another lucky break for me: Black believes that my attack is worth worrying about. He should have simply smashed my center with 23...Nxe4.

24.Bxf6 Rxf6 25.Rd1

Missing a key tactical point that would have almost equalized the game: after 25.b3 Black's Bishop has nowhere safe to go (even 25...Ba6 allows the strong attacking 26.Nd5 with threats to c7) so after 25...d5 26.Nxd5 Bxd5 27.Rxc7 Nf3+ 28.Kh1 Rc6 29.Rxd7 Rc1+ 30.Rg1 Rxg1+ 31.Qxg1 Nxg1 32.exd5 Ne2 Black's advantage is much smaller than in the game.

25...c5 26.e5

There is nothing but bluff in this.

26...Rxf5 27.exd6 Rf6 28.Ne4


Simply hoping to keep Black busy enough until his flag falls.

28...Rh6

Unfortunately this reduces his chances to a draw, while 28...Nf3+ would have killed. 

29.Nxc5 Qxd6

Dropping the whole point, which seems unfair. 

After the game Rybka suggested instead 29...Ne2+ 30.Rxe2 Qf5 with a possible continuation being 31.Re5 Qc2 32.Rde1 Rf8 33.Ne4 Qxb2 34.Re7 Bf7 35.d7 Rg6 36.Ng5 Qd4+ 37.R1e3 Qd1+ 38.Re1 Qd4+ drawing. Not easy to see with a few seconds left.

30.Qxg7 checkmate

Tactical Sloppiness

Here we have a second straight loss for me, the kind better blamed on my tactical sloppiness than on the Jerome Gambit itself, which certainly gave me chances for success.


perrypawnpusher  - wbrandl
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Kf6 8.Qxc5

What difference, if any, does it make that Black's King is on f6?

Before I played 8.Qxc5, I toyed with playing 8.d4, with the threat of 9.B (or Q) g5+ winning Black's Queen. I had obviously forgotten that I had played the move successfully several years ago in perrypawnpusher - whitepandora, blitz, FICS, 2008, (1-0, 41). For the same reason, 8.f4 was also playable, and also better than the text.

8...d6 9.Qe3 N8e7 10.d4 Kf7


Black tried the center/Queenside attack 10...c5 11.dxc5 Qa5+ 12.Nc3 Qxc5 in perrypawnpusher - useche, blitz, FICS, 2010 (1-0, 22)

11.0-0 Rf8 12.f4 Kg8 13.f5 Nh8 14.Nc3 c6


Some of White's compensation for his sacrificed piece is Black's crowded position.

15.Qg3 d5 16.f6 Neg6 17.fxg7 Kxg7 18.Be3


A bit better was 18.Bg5

18...Rxf1+ 19.Rxf1 Nf7 20.Qf3 Ng5 21.Bxg5 Qxg5 22.Qf7+ Kh6 23.exd5 cxd5


After the game Rybka concluded that White had equalized.

24.Nxd5 Bg4 25.Nf4

The Knight needed to go to f6 with the possibility of continuing on to g8. The position would be complicated, but White at worst can expect to draw by repetition.

My move was made with little analysis other than thinking "this looks like a good square" and it allowed Black to bring his Rook into play, winning quickly.

25...Rf8

26.Qxb7 Rxf4 27.Qxa7 Rxf1+ 28.Kxf1 Qf4+ White resigned
