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...

perrypawnpusher - Hywel2
Chess.com, Italian Game tourney, 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 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".

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 

analysis diagram








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

Two Positions

In the following game my opponent out-played me, encouraging me to extend a shell of "Jerome pawns" which he then cracked like an egg. I'd like to look at a couple of interesting positions from the game, neither of which I "solved" correctly.

 perrypawnpusher - mconst
blitz, FICS, 2010

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 Ne5

This is the first position. Black is clearly being provocative, asking for the d-pawn or the f-pawn to kick the Knight to g4. I've not seen it before.

Instead, I've seen 9...Nf6 in perrypawnpusher - hogmaster, JG3 thematic, ChessWorld, 2008 (1-0, 37); perrypawnpusher - joejox, blitz, FICS, 2009 (1/2- 1/2, 27); perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23); perrypawnpusher - Mences, blitz, FICS,  2009 (1-0, 38); perrypawnpusher - andrecoenen, blitz, FICS, 2010 (1-0, 25);  perrypawnpusher - SkypeFro, blitz, FICS 2010 (1-0, 39);   perrypawnpusher - BishopChris, blitz, FICS, 2010 (1-0, 22);

I've also faced 9...Be6 in perrypawnpusher - jamtaylo, blitz, ChessWorld Welcome JG, 2009 (1-0, 27).

10.0-0 Nf6 11.f4

Likely better is 11.d4, which would cause me to re-think my understanding of how to play this position. The attraction of the move is obvious: kicking the Knight on e5 and opening the c1-h6 diagonal for White's dark squared Bishop. It also means that White should then answer 11...Neg4 (not the best response) with 12.Qd3, giving up, at least for the moment, the idea of pinning Black's Knight along the f-file with either the Rook or Queen and then attacking it with e4-e5.

11...Neg4

This is probably not as solid as 11...Nc6 but it is much more annoying.

12.Qf3 Nh6

13.h3 Kf7 14.e5 Ne8 15.g4 Rf8 16.Qd5+ Be6 17.Qxb7 Qh4

Here's the second position of interest. The question is: Is Black bluffing?

He had the choice of the ordinary 17...dxe5 18.fxe5+ Kg8 19.Rxf8+ Kxf8 20.Qe4 Nf7 which is about equal.

Instead, he offers a Rook.

18.Qg2

I played this too quickly, but it is worth looking at 18.Qxa8 d5, locking the Queen out. The alternatives to the pawn move, 18...Qxh3, 18...Nf6 and 18...Nxg4, are all well met by 19.Qg2.

When White then covers his h-pawn with 19.Kg2, Black has 19...Nd6, exposing an attack on the Queen.

As Her Majesty runs back home, Black breaks through: 20.Qxa7 Ne4 21.Qa3, however I have not been able to find anything better for Black than either 21...Bxg4 or 21...Nxg4 each which yield nothing more than a draw through perpetual check after 22.hxg4.

18...Rb8 19.f5 Bc8 20.d4 Bb7 

The game is complicated, and my play from here on out is not good.

21.Qh2

White needed to shield himself from that Bishop with 21.d5 dxe5 22.c4, when Black might have a slight edge.

21...Kg8

Prudent, but there were good attacking chances with 21...Nxg4.

22.Nd2

White needed to get rid of that Knight with 22.Bxh6
22...Nxf5

Even more deadly was 22...Nxg4, but my game was collapsing fast.

23.gxf5 Qxd4+ 24.Rf2 Rxf5 25.Nb3 Qd1+ White resigned
