More Errors in Thinking 3.1

The title of this post comes from a couple of previous ones - "More Errors in Thinking" and "More Errors in Thinking 2.0" - and can be explained by the truism I related earlier

One of my interests in exploring the Jerome Gambit comes from observing - and occasionally provoking - "errors in thinking". Essentially, the only way White can win is if Black errs - sometimes in the most fascinating of ways.

In the first of the two posts I presented the Jerome Gambit game perrypawnpusher - Hywel2, Chess.com Italian Game tournament, 2015, with the gushing note

For a while it looked like it was going to be one of my best Jeromes ever, thanks to some fun tactics - but I fell victim to my own "error in thinking", and it was all for naught...

In the second of the two above posts, I presented the game again, adding notes and suggestions by Bill Wall, longtime Jerome Gambit Gemeinde member.

It all was in the service of some mental hand-wringing, the likes of which I have done before, for example, about a year ago in "Jerome pawns - Clowning Around"

After my discouraging loss with the Jerome Gambit in my previous Chess.com Italian Game tournament (perrypawnpusher - Buddy_Thompson), I knew that I had to cook up something new, or risk facing a future opponent who just "looked the refutation up" (and not even on this blog, mind you, but in my recent games on Chess.com).

Such worry bore fruit, however, in terms of a win in my return game with djdave28, as the post showed.

So - recently I played a couple of Jerome Gambits, one too-quickly leading "Toward Disaster" with the other "following, step-by-step, a recent loss of mine from a Chess.com Italian Game tournament."

As you might guess, that "recent loss" was the game chronicled in "More Errors in Thinking" and "More Errors in Thinking 2.0", perrypawnpusher - Hywel2, Chess.com Italian Game tournament, 2015.

So, "without further ado" as they say, let us take a look at my latest Jerome Gambit win, (with earlier notes cribbed from earlier posts).

perrypawnpusher - Heler, 
Chess.com, Giuoco Piano tournament, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.O-O Kf7 11.f4 Re8 12.f5 Ne5 13.d4 

I have also tried 13.Nc3 in perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23); perrypawnpusher - darqknight, blitz, FICS, 2011 (0-1, 63); perrypawnpusher - CorH, blitz, FICS, 2011 (1-0, 24); and perrypawnpusher - yasserr, blitz, FICS, 2011 (1-0, 32).

13...Nc6

Oddly, this natural move was a TN according to The Database until perrypawnpusher- Hywel2, Chess.com, Italian Game tournament, 2015

Instead, 13...Neg4 was seen in Vazquez,A - Carrington,W, Mexico, 2nd match 1876 (1-0, 34);Wall,B - Vijay,V, Chess.com, 2010 (1-0, 22) and perrypawnpusher - whitepandora, blitz, FICS, 2011 (1-0. 64).

14.Nc3 Kg8 15.Qd3 Kh8 16.Bg5 Qd7

So far, all replay of the earlier game; but things were about to change.

More Errors in Thinking 2.0

In response to "More Errors in Thinking" I received an email from Bill Wall, one of the top modern day Jerome Gambiteers, with notes about my recent game against Hywel2. I will reprise the column, adding Bill's thoughts in red. Thank you, Bill!

One of my interests in exploring the Jerome Gambit comes from observing - and occasionally provoking - "errors in thinking". Essentially, the only way White can win is if Black errs - sometime in the most fascinating of ways.

The following game is my most recent Jerome Gambit from the Chess.com Italian Game tournament (see "Yet Once Again Into The Fray"). For a while it looked like it was going to be one of my best Jeromes ever, thanks to some fun tactics - but I fell victim to my own "error in thinking", and it was all for naught...

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.O-O Kf7 11.f4 Re8 12.f5 Ne5 13.d4

I have also tried 13.Nc3 in perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23); perrypawnpusher - darqknight, blitz, FICS, 2011 (0-1, 63); perrypawnpusher - CorH, blitz, FICS, 2011 (1-0, 24); and perrypawnpusher - yasserr, blitz, FICS, 2011 (1-0, 32).

13...Nc6

Oddly, this natural move is a TN according to The Database. Instead, 13...Neg4 was seen in Vazquez,A - Carrington,W, Mexico, 2nd match 1876 (1-0, 34); Wall,B - Vijay,V, Chess.com, 2010 (1-0, 22) and perrypawnpusher - whitepandora, blitz, FICS, 2011 (1-0. 64).

14.Nc3 Kg8 15.Qd3 Kh8 16.Bg5 Qd7

After 16...Qd7, I would have played 17.Bxf6 right away. After 17...gxf6 18.Nd5 Qg7 19.c3, then 20.Rf3 looks a little bit more solid.

17.Rae1 b6

I am always impressed when the masters of the Jerome Gambit are able to "make something out of nothing" in their games. It is not so easy for me.

18.Bxf6 gxf6 19.Nd5 Qg7 20.Rf3 a5 

After 20...a5, I like 21.Qc3 instead of 21.c3, attacking the knight. After 21...Bb7 22.Nf4 and 23.Rh3 looks OK for white.

21.c3 Ba6 22.Qd2 Bc4 

After 22...Bc4, instead of 23.Rg3, forcing the queen to move, perhaps to a better square, I would try 23.Nf4 Bxa2 24.Rh3, threatening 25.Ng6+ and perhaps 26.Rg3 after that.

23.Rg3 Qf7 24.Nf4 Bxa2 25.Ree3

I am not sure what my opponent made of this move. Perhaps he thought I was still shuffling pieces.

Instead of 25.Ree3, I might have played 25.Rh3, threatening 26.Ng6+, but it may fizzle to a draw after 26...Rg8 26.Ng6+ Rxg6 27.fxg6 Qxg6 28.Qf4 and 29.Rh6.

25...Rg8 26.Ng6+!?

White has only a pawn for his sacrificed piece, but this new sac changes everything.

26...hxg6 27.Rh3+ Kg7 28.Rh7+

The main idea: if now 28...Kxh7, then 29.Rh3+ Kg7 30.Qh6 mate. Black, instead, gives up his Queen.

28...Kf8 29.Rxf7+ Kxf7

Houdini gives a deep look, and evaluates the position as being equal. A couple of lines to share what it sees: 30.Qd3 (looking at the light squares on the Queenside and Black's two loose minor pieces) Ne7 31.Qb5 gxf5 32.exf5 Rae8 33.g3 c6 34.Qxb6 Nxf5 35.Qc7+ Re7 36.Rxe7+ Nxe7 37.Qxd6 a4 38.Qf4 Be6 39.d5 Bxd5 40.Qxa4; or 30.Qc2 (to trap the Bishop) a4 31.e5 Ne7 32.fxg6+ Rxg6 33.exd6 Nd5 34.Rg3 Rxg3 35.hxg3 Bb3 36.Qd3 cxd6 37.c4 Ne7 38.Qh7+ Kf8 39.Qh6+ Kf7 40.Qh7+ draw

I wanted to take advantage of Black's loose pieces, too, before his R + B + N got coordinated and out-played my Queen.

30.fxg6+

Instead of 30.fxg6, I would try to keep it complicated with 30.Qc2 and with the threat of 31.Qa4, winning a piece (threatening bishop and knight), or 31.b3, trapping the bishop.

30...Rxg6 31.Rh3 Rag8 32.Rh7+ R8g7 33.Rxg7+ Rxg7 34.Qd1 Be6

Now is the time for White to continue his escape with 35.Qh5+ Rg6 36.Qh7+ Rg7 37.Qh5+ draw, as any other line by Black would drop a minor piece to a Queen check and fork.

But - what is this?? My opponent, having played strongly the whole game, has suddenly fallen for a simple pawn fork?? What good fortune!

What an error in thinking! On my part, that is.

35.d5?

Allowing Black to quickly pull his game together.

Instead of 35.d5? which allows 35...Bg4!, I would have played 35.Qh5+ Rg6 36.Qh7+ Rg7 37.Qh5+ Rf6, take the draw and call it a day.

35... Bg4

I had looked at 35...Bh3, but had totally overlooked the text.

After some discouraged piece-shifting, I gave up the ghost.

36.Qe1 Ne5 37.Qe3

I looked at your last game and you thought there might be a way I could prevail. Not after 37.Qe3. After 36...Ne5 was played (you threatened dxc6), you played 37.Qe3? But after 35...Ne5, Black's threat is 36...Bf3 or 36...Bh3 as the rook pins the king and you can't take the bishop. So you have to play either 37.Kf1 or 37.Kh1. I think 37.Kf1 is slightly better to get out in the middle of the board in the endgame. Maybe there is something with Qh4 later or just h3. So after 37.Qe3, White' game looks lost. 

37...Bf3 38. g3 Bh5 39. h3 Nc4 40. Qf2 Bg6 41. Qe2 Ne5 42. g4 Ke7 43. Kf2 Kf8 44. Qa6 Re7 White resigned

Black's pieces are cooperating, and it is only a matter of time before they begin chopping away at White's position (starting with Pe4).

I am sure that Jerome Gambit stalwarts like blackburne, Bill Wall and Philidor1792 would find a way to prevail, even in this position, but I felt "lost" after my 35th move, and couldn't see my way out - perhaps the final "thinking error".

(In the two other second round games with White in this tournament, I am playing an Italian Four Knights game [with the help of chessfriend Yury Bukayev's opening analysis] and facing a Hungarian Defense [I did not follow Yury's suggestion, and may come to regret it. {Wow! I was just offered a draw, which I took quickly}] - Rick)

More Errors in Thinking

One of my interests in exploring the Jerome Gambit comes from observing - and occasionally provoking - "errors in thinking". Essentially, the only way White can win is if Black errs - sometime in the most fascinating of ways.

The following game is my  most recent Jerome Gambit from the Chess.com Italian Game tournament (see "Yet Once Again Into The Fray"). For a while it looked like it was going to be one of my best Jeromes ever, thanks to some fun tactics - but I fell victim to my own "error in thinking", and it was all for naught...

Black's pieces are cooperating, and it is only a matter of time before they begin chopping away at White's position (starting with Pe4).

I am sure that Jerome Gambit stalwarts like blackburne, Bill Wall and Philidor1792 would find a way to prevail, even in this position, but I felt "lost" after my 35th move, and couldn't see my way out - perhaps the final "thinking error".

Not Right Enough

Sometimes, it seems, you can do almost everything right - and still not be successful.

In the following Jerome Gambit game, Black counter-attacks while securing the safety of his King. When White's pawns get too frisky, he returns the sacrificed material and transitions to what looks like a draw-able endgame.

And then he loses.

As ever, especially in a 3-minute game, Phiilidor 1792 is a force to be reckoned with.  


Philidor 1792 - guest2498
3 0, www.bereg.ru, 2014

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 

10.Nc3 c6 11.0-0 Kf7 12.f4 Re8 13.f5 Ne5 14.d4 Nc4

Harassing the Queen with the Knight is a known theme, but probably 14...Neg4 was a stronger way to do it, as in perrypawnpusher - andrecoenen, blitz, FICS, 2010 (1-0, 25) and perrypawnpusher - darqknight, blitz, FICS, 2011 (0-1, 63). 

15.Qf3 Kg8

Curiously, reaching perrypawnpusher - Nadant, blitz, FICS, 2010 (0-1, 59) only with White to move, not Black.

Black has castled-by-hand, and White will soon be ready to get his "Jerome pawns" rolling. The defender still has an edge. 

16.b3 Nb6 17.Bg5 Qe7 18.Rae1 Qf7 19.e5 dxe5 20.dxe5 Nfd5 21.e6 Qf8 

The pawns are beginning to look ominous, so Black returns material.

22.Ne4 Bxe6 23.fxe6 Qxf3 24.Rxf3 Rxe6 25.c4 Rae8 26.cxd5 Rxe4 27.Rxe4 Rxe4 28.dxc6 bxc6 

White's Bishop vs Knight and better pawn position give him a slight edge. He outplays his opponent the rest of the way.

29.Rc3 Re6 30.Kf2 h6 31.Bh4 Nd5 32.Rc5 g5 33.Bg3 Ne3 34.Bb8 Ng4+ 35.Kf3 Nf6 36.Bxa7 Nd5 37.Rc2 Kf7 38.Bc5 Kg6 39.a4 h5 40.a5 g4+ 41.Kf2 Nf4 42.a6 Nd3+ 43.Kg3 Kg5 44.h4+ gxh3 45.Kxh3 Nxc5 46.Rxc5+ Black resigned

Don't Blame the Jerome Gambit (Part 1)

My opponent in the following game had faced the Jerome Gambit before, and shortly after our match he played it, victoriously, of course... I would like to think that he learned something about the opening from me, but improved on the follow-up.


perrypawnpusher - darqknight
blitz, FICS, 2011

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

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

7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6

10.0-0 Kf7 11.f4 Re8 12.f5 Ne5 13.Nc3 c6

So far we have a fairly typical 6...Ng6 Jerome Gambit, with Black planning to castle-by-hand and White using his "Jerome pawns" to kick a Knight or two. Black has an edge, but it is not something to put off the Jerome Gambiteer.

14.d4 Neg4 15.Qf3 Qe7

Putting extra pressure on the White e4 pawn, but this gives the first player a needed tempo. 

16.h3 Nh6 17.Bxh6 gxh6

White's minor piece is developed, and his Rooks are ready for action; compare with Black's Queen Bishop and Queen Rook.

18.Rae1 Rg8

Thinking "counter attack on the wing" but the center is where the play will be. 

19.e5 dxe5 20.dxe5 Nd5

The fierce "Jerome pawns" face the enemy King and Queen and snarl menacingly. Black would have done better to give a piece back with 20...Kg7 21.exf6+ Qxf6 but he still would have much the worse game.

So: a score of moves played, none of them looking like howlers for Black, and yet White is poised to crush.

Almost.

21.Qh5+ Kf8 22.Qxh6+

Capturing Black's Knight (Rybka 3 does not think he can afford to recapture) with 22.Nxd5 followed by 23.Nf4 (if the White Knight is not captured) or 23.e6 would have been more powerful than mere pawn-hunting. I was playing "strong moves" without a "strong plan" in mind.

22...Ke8

Interposing the Queen had to be safer.

23.f6 Qf7

24.Nxd5

The alternative 24.Ne4 contained more threats.

White is still better, but I was still playing move-to-move, and every moment that I do not put my opponent away, he gets another chance to put me away, or I get a chance to do myself in.

24...cxd5 25.Qe3

Taking the "short" view of things.

Had I looked "longer" it would not have been hard to find 25.e6 Bxe6 26.Rxe6+ Qxe6, removing the blockader, so that after 27.f7+ Kd7 28.fxg8Q Rxg8 29.Qxh7+ the game has simplified to one where White is two pawns up, and Black has little compensation.

That is the kind of combination that the Big Boys don't miss.

25...Be6

Psychologically, the end of the game.

While White may be even (or a tiny bit better), the blockade of his pawns stifles his initiative and the rest of the game sees a transfer of the balance, step-by-step, into Black's hand.

26.Qd3 a6 27.Kh2 Rc8 28.c3 Rc4 29.b3 Rh4 30.Rf3 Qh5 31.Ree3

The game is still even, but what have I done besides shift pieces?

31...Qh6

Okay, okay, this is the kind of oversight that an opponent will sometimes toss my way, even when it is highly undeserved.

Especially when it is highly un-noticed.

32.Rg3

If you saw the opportunity for White to sacrifice both "Jerome pawns" and suddenly come roaring back, good for you!

Take a look at 32.f7+ Bxf7 33.e6.

analysis diagram





Now 33...Bxe6 is met by 34.Qxd5 Rg6 35.Qxb7 and suddenly Black's King faces horrible mating threats.

Rybka 3 prefers 33...Rxg2+, but that is a loser, too, after the straight-forward 34.Kxg2 Qg6+ 35.Rg3 Qxd3 36.exf7+ Kf8 37.Rxd3 Kxf7. A Rook is a Rook is a Rook.

32...Rxg3 33.Rxg3 Qf4 34.Qe3 Qxe3 35.Rxe3 Rf4 36.Kg3

36...Rf5 37.Kh2 Rg5 38.g3

Hoping to activat the Kingside pawns to help in the fight against the Bishop, but a more effective way was to first get rid of the Rooks, starting with Rg3, headed toward g7, forcing Black's hand. Still, the defense will hold. 

38...Rh5 39.h4 Rf5 40.Kg2 Kf7

The blockade remains supreme!

41.g4

Rushing headlong into disaster. 

41...Rf4 42.g5 Rxh4 43.Kf2 Rg4 44.Rg3 Rxg3 45.Kxg3 Kg6

46.Kf4 b6 47.a4 b5 48.axb5 axb5 49.c4 dxc4 50.bxc4 bxc4

All in vain: even if White reaches a K vs K + B + RP endgame, it is the Bishop of the Right color.

51.Ke4 c3 52.Kd3 Kf5 53.Kxc3 Kxe5 54.Kd3 Kf5 55.Ke3 Kxg5 56.Kf3 Kxf6 57.Kg3 Kg5 58.Kh2 h5 59.Kg3 h4+ 60.Kh2 Kg4 61.Kg2 h3+ 62.Kh2 Bd5 63.Kg1 Kg3 White resigned

A very nice recovery by darqknight!
