Pawns 1, Piece 0

Sometimes White wins by attack in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and sometimes he has to "play out" the game and use his pawns against his opponent's extra piece. Proper defense by Black should save at least half of the point, but that doesn't always happen...

perrypawnpusher - CorH

blitz, FICS, 2011

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

4...Kxf7 5.Nxe5+ Nxe5

Our earlier game, featuring 5...Kf8, was a pretty good example of Black and his extra piece out-duelling White and his extra pawns (although I had my chances)  perrypawnpusher - CorH, blitz, FICS, 2009, (0-1, 74).

6.Qh5+ Ng6 7.Qd5+

A check of The Database shows that I don't always play this "nudge": 7.Qxc5 d6 8.Qe3 Nf6 9.0-0 Re8, perrypawnpusher - MoonCat, blitz, FICS, 2007, (1-0, 29).


7...Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.0-0 Kf7

Returning the extra tempo lost by the "nudge".

11.f4


Also seen: 11.Nc3 as in perrypawnpusher-joejox, blitz, FICS, 2009 (½-½, 27).

I did not find Rybka's apparent "let's not risk anything else" recommendation that it made after the game to be appealing: 11.d4 Re8 12.Qb3+ Kf8 13.f3 c6 14.c4 Qb6 15.Be3 Be6 16.Nc3 Bf7 17.Rfe1

11...Re8

Of course, Black's Knight can aways kick White's Queen instead, with 11...Ng4 as in perrypawnpusher - Feestt, blitz, FICS, 2009 (1-0, 19).

12.f5 Ne5


Instead, the precipitous 12...Rxe4 did not work at all after 13.fxg6+ hxg6 14.Qxe4 in perrypawnpusher - bnxr, blitz, FICS, 2011 (1-0, 29).


13.Nc3


I wanted to play 13.d4 but could not figure out how to meet 13...Neg4. The moves are from Vazquez -Carrington, Mexico, 2nd match, 1876 and I should have remembered them for historical reasons, if no others: 14.Qb3+ Kf8 15.h3 Rxe4 16.hxg4 Rxg4 17.Qf3 c6 18.Nc3 d5 19.Bf4 Kg8 20.Be5 h5 21.Rae1 Bd7 22.Re3 Qb6 23.b3 Rf8 24.Na4 Qb4 25.Nc5 Bc8 26.c3 Qb6 27.Bxf6 gxf6 28.Qh3 Rg5 29.Ne6 Bxe6 30.fxe6 Qc7 31.e7 Re8 32.Qe6+ Kh8 33.Qxf6+ Rg7 34.Qf8+ Black resigned

13...Kg8


Prudent. There was always the kick at the Queen with 13...Nc4 as an alternative, although it did not lead to much difference after 14.Qd4 Ne5 15.d3 Kg8 in perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23).


14.d4 Neg4

Of course.

15.Qf3 Bd7


An opponent tried 15...c6 in perrypawnpusher - avgur, blitz, FICS, 2010 (1-0, 23) but the pawn probably needed to take two steps. 


16.h3 Nh6 17.Bxh6 gxh6 18.Rae1 Kh8

19.e5 dxe5 20.dxe5 Ng8

Active defense with 20...Bc6 (followed by 21...Rg8) was more likely to be successful in holding back the pawns, reaching  a balanced game.

21.f6 Bc6 22.Qf4 Rf8 23.f7

White's "Jerome pawn" threatens to win back the sacrificed piece: 23...Qg5 24.Qxg5 hxg5 25.fxg8/Q+ Kxg8. White would be a pawn better, but the win would be far off.

Instead, Black saves his Knight and loses his King.

23...Ne7 24.Qf6 checkmate

Lazy, lazy, lazy

I ran across the following game the other day, one that I played last year, that I had not presented on this blog.

No, it is not because I lost the game that it had slipped my mind. It is because how I won the game.

10.Qf3+ Ke8

Reflex.

11.Qxh5+ g6 12.Qg5

Two pawns up, my brain dropped into L for Lazy: Why think when you can just push pieces? This is a habit that has hurt me in the past, so it is actually painful to see it be successful in this game.

12...Qxg5 13.Bxg5 Rf8 14.0-0 h6

This does not help, giving a free pawn. From now on I play almost on auto-pilot.

15.Bxh6 Rf7 16.Nc3 c6 17.Be3 a5 18.Bxc5 dxc5

Hardly a Hopeless Patzer

I am going to leave the final words on the "Ruy Lopez Jerome Gambit" (see "...or should they?") to the host of the blog "Hopeless Patzer", whose perspective I find both entertaining and educational. (I have added a few diagrams.)

BlackKnight8 - lindseyann
www.ChessWorld.net , 2008

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.Nxe5 Qd4 6.Nxf7

Everything was book until now. Although, taking the pawn is not the best, doing this with the knight is even worse.

6...Qxe4+ 7.Kf1 Qc4+

This move lets me win the knight and retain my ablilty to castle.

8.Kg1 Qxf7 9.d3 Bc5 10.Be3 Bd6 11.f3 Nf6 12.Kf2 0-0

Ng4+ was slightly better here. It would have allowed me to simplify, but I was trying to get as many pieces as I could pressuring his king.

13.Re1 Bxh2 14.Nc3 Nd5

Once again, Ng4+ was the best move.

15.Rh1 Be5 16.f4 Nxe3

This was not the best move, but it caused a flood of pieces that he could not recover from.

17.Kxe3

And with this move he stepped into a mate that was easy to spot.

17...Qxf4+ 18.Ke2 Bg4+

Well, I missed the mate in 1 this time, but not the next.

19.Ke1 Qf2 checkmate

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6

I am really not a fan of the Ruy Lopez. I usually manage to make a mess of things. Let's see how this works out.

5.Nxe5 Qd4 6.Nxf7 Qxe4+ 7.Qe2 Qxe2+ 8.Kxe2 Kxf7

Turns out he made a mess of this. I was probably beefing up on my openings when this was played. Now neither of us are able to castle, but at least I'm up a piece.

9.d4 Nf6 10.Rd1 Bg4+

Developing my bishop with a skewer that is easily defended.

11.f3 Re8+ 12.Kf2 Bf5 13.Nc3 c5

I probably should have just taken the material with 13...Bxc2. But, I was trying to get my dark-square bishop into the game. He could have protected the g1-a7 diagonal with 14. Be3, but he didn't.

14.dxc5 Bxc5+ 15.Kg3 Nh5+

This move was no good and gets me into trouble in a minute.

16.Kh4 g6

I miss the completely obvious response 17.g4

17.g4

At this point in the game, I was completely convinced that Be7 would be mate. I did not notice his bishop quietly waiting to come to the defense.

17...Bf2+ 18.Kh3

Now I realize his bishop can come to the defense. I actually wrote in my notes during the game: Bxc2 trying to trick him into playing Rd2, then my mate works. This is what happened, but its never good to rely on your opponent to make a big blunder to win.

18...Bxc2 19.Rd2 Nf4 checkmate

Long Lost Cousin?!

Much like the long lost cousin who you wish had stayed lost, the Knight sacrifice in the Exchange Variation of the Ruy Lopez bears a family resemblance to the Jerome Gambit. 

Jerome Gambit

Ruy Lopez Jerome Gambit

Still, as suggested in the notes to Pigjuice - perrypawnpusher, blitz, FICS, 2011, 6...Qxe4+ was stronger than the move played and reduces the resemblance. The following ICCF game, where a 2200+ player is schooled by someone rated over 450 points lower, puts things in perspective.

Christiaens,R (2242) - Dumont,G (1777)
Tournoi Accession 009, ICCF, 2009

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6

The good old Ruy Lopez, Exchange Variation.

Black's coming pawn grab and Knight sacrifice are not considered part of his best defense.

5.Nxe5 Qd4 6.Nxf7

Recommended by Rybka is 6.Nf3 Qxe4+ 7.Qe2 Qxe2+ 8.Kxe2 Be6 9.Re1 0-0-0 10.d3 h6 11.Kf1 Nf6 12.h3 Bd6 13.Nbd2 Rhe8 14.b3 Nd5 15.Nc4 where Black has an edge.

6...Qxe4+

If, instead, the weaker 6...Kxf6, the game takes on a resemblance to the Jerome Gambit after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5 Kf8 6.Nxc6 dxc6. Amusingly, in the Spanish Game the White Bishop is exchanged on c6 and the Knight is sacrificed on f7, while in the Jerome Gambit the Bishop is sacrificed on f7 and the Knight exchanged on c6.

7.Kf1 Kxf7 8.Nc3 Qf5 9.h3 Bb4 10.a3 Bxc3 11.dxc3 Nf6

White's compensation for the piece is negligible. His timid play hastens the end.

12.b4 Be6 13.Bb2 Bc4+ 14.Kg1 Rad8 15.Qc1 Rhe8 16.Kh2 Re2 17.Re1 Qxf2 18.Rf1 Qxg2 checkmate

I probably will continue to investigate the "Ruy Lopez Jerome Gambit" for historical purposes (and I have added the couple hundred games that I have uncovered to The Database), but after tomorrow's post –  letting a self-styled "hopeless patzer" have the final words – I will not inflict it further upon readers.

Ruy Lopez Jerome Gambit??

Still puzzled and a bit impressed by the opening that Pigjuice sprung on me yesterday (see "...or should they?") I did a Google search, and much to my surprise ran across the following as part of a discussion of the Exchange Ruy Lopez at ChessGames.com

Nov-13-04 drukenknight: Spanish Exchange (N sack on f7). You know w/ my new "back to the basics" approach to chess, I decided to start looking into the exchange spanish, but it seems pretty freakin stupid. I always want to grab that pawn on e5 but it never seems to work out, but wait a minute! WHy can't white simply sack the N on f7 and gain 2 pawns and go on the attack? What could be more basic than that.....?

"No, stupid moron, you cant do that, no one does that, look here stupid...

Maybe evaluation of this depends on how good your computer assistant is.

So maybe the Knight sacrifice in the Ruy Lopez Exchange line 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.Nxe5 Qd4 6.Nxf7

wasn't something that Pigjuice had made up on the spur of the moment, I wondered.

I checked the FICS games database and found three more games by Pigjuice with that line. Interesting... "Malice aforethought" as they say.

In fact, in the last three months of play at FICS the sac had been played over 200 times. That was "something" but I wasn't exactly sure what kind of "something" – for example, White scored under 20% in those games...

More investigation is needed.

...or should they?

I once wrote that "perhaps not every opening should be Jerome-ized..." I've been re-thinking that: recently an opponent in a 3 0 blitz game found a piece sacrifice that turned that respectable opening into something remarkably Jerome-ish, a trick that gave me quite a headache.

Pigjuice - perrypawnpusher
blitz 3 0, FICS, 2011

1. e4 e5 2. Nf3 Nc6 3. Bb5

The Ruy Lopez, I know. Just wait a few moves.

4...a6 4.Bxc6 dxc6 5.Nxe5

A slip. I think that it was unintentional.

5...Qd4 6.Nxf7

Making things interesting.

6...Kxf7

The resemblance to a Jerome Gambit variation (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Kf8 6.Nxc6 dxc6) is remarkable.

Ruy Lopez

 


Jerome Gambit

 

In the Ruy Lopez White's Bishop was exchanged on c6 and his Knight was sacrificed on f7. In the Jerome Gambit, the Knight was exchanged on c6 and the Bishop was sacrificed on f7. You can not see the difference.

I do not think that having his Queen developed instead of his Bishop is an improvement for Black over the Jerome line. Having the King on f7 instead of f8 is probably helpful in terms of castling-by-hand.

The facts were clear, though: I was now defending a Jerome Gambit (I'll think about calling it a "Ruy Lopez Jerome Gambit" later) – and my clock was ticking.

7.Qf3+ Qf6

An endgame – without White's attacking Queen – appealed to me, but 7... Nf6 was probably better. My opponent was not interested.

8.Qb3+ Qe6 9.Qf3+ Nf6

10.Nc3 Bb4 11.d3 Rf8 12.Bd2 Kg8

13.O-O Qg4 14.Qe3 Bd7 15.a3 Bd6 16. Ne2 Rae8

I was holding my own, although after the game Fritz10 suggested 16...Nd5 17.Qg5 (if 17.exd5 Rae8) 17...Qxe2 18.Rae1 Qg4 19.exd5 Qxg5 20.Bxg5 cxd5 as a way to a comfortable Queenless middlegame.

The next move I had a similar idea, but it did not work out as well.

17.Ng3 Nd5 18.Qa7 Bc8

Overlooking a couple of things.

19.exd5

That was one of them: dropping a piece. Now I was down a pawn with less than a minute to play, no increment.

The other thing? The pawn that I protected was not worth it, as 18...Nb6 would have shown: 19.Qxb7 Rb8 20.Qxa6 Ra8 21.Qb7 Rfb7 and the Queen is lost.

19...cxd5 20.f3 Qg6 21.Qf2 Bxg3 22.Qxg3 Qxg3 23.hxg3 c6

I callously planned on reaching a Bishops-of-opposite-colors endgame that I could shuffle pieces in quickly – important, as I not only had little time left, I had less than my opponent.

24.Rae1 Rxe1 25.Rxe1 Kf7 26.f4 Re8 27.Rxe8 Kxe8

If time were not an issue, we probably would have split the point here, and I would have congratulated my opponent – rated 200 points below me – on his opening play creativity.

I was ready to very quickly do "nothing". My opponent's downfall was that he was trying to quickly do "something."

28.Bc3 g6 29.Bg7 h5 30.Bh6 Kf7 31.Bg5 Ke6 32.Kf2 Kf5 33.Ke3 Be6 34.c3 a5 35.d4 a4 36.Kd3 b5

Don't go away quite yet. There are some interesting positions to come.

37.Kc2 Kg4 38.b3

I was pleased to see my opponent "thinking" instead of "shuffling". Thinking takes more time.

38...axb3+ 39.Kxb3 Kxg3 40.a4 bxa4+ 41.Kxa4 Kxg2 42.Kb4 Kg3

In Bishops-of-opposite-colors endgames the blockade of enemy pawns by both Bishop and King is essential. I realized that White's King excursion gave me a chance to un-blockade my Kingside pawns and I squeezed a few thoughts out of my brain...

43.Kc5 Bd7

More straight-forward, winning White's Bishop, was 43...h4, although it needed some precision: 44.Bxh4+ Kxh4 45.Kxc6 Kg4 46.Kd6 Kf5! Instead, if Black abandons his Bishop to go directly to Queening a pawn he gets his wish, but after 46...Kxf4 47.Kxe6 g5 48.c4 dxc4 49.d5 c3 50.d6 c2 51.d7 c1=Q 52.d8=Q the Q + K + P vs Q + K endgame takes a whole lot of moves – and time – to win.

44.Kd6 Be8

I was ahead of my opponent in time (what was left of it) here, but thinking was still a precious commodity. It seemed like time to abandon my Bishop and win Pigjuice's.

45.Ke7 h4 46.Kxe8

Giving up the Bishop first with 46.Bxh4+ leads to the kind of endgame that I was familiar with and had won on several occasions: 46...Kxh4 47.Kxe8 Kg3 48.Kd7 Kxf4 49.Kxc6 g5 50.Kxd5 g4 51.Kc6 g3 52.d5 g2 53.d6 g1=Q 54.d7 Qg5 – Black's Queen holds the advanced pawn and when Black's King joins the fight, the pawns will be won and then the enemy King checkmated.

Still, that would take moves, thinking, and time – more by Black than White, it seems – so it was probably White's more practical chance. Now, Black's pawn can promote.

46...h3

47.f5

The same idea, without giving up the f-pawn, would arise after 47.Bd8 h2 48.Bc7 h1=Q 49.f5+ Kg4 50.fxg6 although, like in the note to White's 46th move, Black's Queen and King can control White's passer:  50...Qh6 51.Kf7 Kf5 52.g7 Qe6+ 53.Kf8 Qc8+ 54.Kf7 Qxc7+ 55.Kf8 Qd8+ 56.Kf7 Qf6+ 57.Kg8 Kg6.

The cooperation between Black's Queen and King is worth knowing about for this kind of ending.

47... gxf5 48.Bf6 h2 49.Be5+ f4 White forfeited on time

Whew!

Hats off and a deep bow of respect to my opponent.

...Bf8-d6

Some moves for Black and or for White in an opening are "thematic" – the kind of moves that are played frequently, because they accomplish the tactical or strategic aims of that line.

Some are not.

eltemible - DJJDev
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5

That unnamed "line of play that everyone should know about".

4.Bxf7+

For the record, 4.Nxe5 is best.

4...Kxf7 5.Nxe5+ Ke6 6.d4 Bd6

I don't have anything against the move ...Bf8-d6 in the abstract; I am sure that sometimes it is an ambitious move (I am thinking of the Four Knights Game), but as in the Jerome Gambit game HauntedKnight - sarahdaniel, blitz, FICS, 2011 that we looked at a short time ago, and as in the Blackburne Shilling Jerome Gambit game HJBuck - fastglass, blitz, FICS, 2011, it is also a poor fit in this related line: Black does better with 6...d6. See "The Psychology of Error in Chess".

7.Qg4+

Simply the beginning of The End.

7...Ke7 8.Bg5+

Okay, it seems that The End has been postponed. It was expected to arrive with 8.Qxg7+ Ke6 9.Qf7 checkmate, but it still is not far away.

8... Nf6

The sad alternative was for Black's King to step aside and let his Queen be taken without even the recompense of recapture, as 8...Ke8 9.Bxd8 Kxd8 loses a Rook to 10.Qxg7. Painful.

9.Bxf6+ gxf6

As above, "best" was 9...Ke8 10.Bxd8 and again 10...Kxd8 would lose a Rook to 11.Nf7+.

It is no wonder that Black chose a faster exit.

10.Qg7+ Ke8 11.Qf7 checkmate

It is not as if DJJDev had not been warned. A year and a half ago he had played 6...Bd6, and his opponent, Jerome Gambit Gemeinde member UNPREDICTABLE, had also found 7.Qg4+, although after 7...Kf6 The End was again postponed – if for more moves, then also with more pain – 8.Qh4+ (or 8.Bg5#) 8...Ke6 9.Qxd8 Be7 10.Qxc7 Nc6 11.d5+ Kf6 12.dxc6 bxc6 13.Nxd7+ Ke6 14.Qxc6+ Kf7 15.Ne5+ Kf8 16.Qxa8 Nf6 17.Qxc8+ Ne8 Black resigned.
