Chess Is Not Life

Despite what different masters are reported to have said, it is not true that "Chess Is Life". Sometimes it appears that "life" is what keeps us busy, and occasionally from playing chess, though...

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 Qf6

10.Nc3

The is one move among many possible.

Bill Wall has played 10.d3, as in Wall,B - G3LC, PlayChess.com 2011 (1-0, 22).

Louis Morin has show an interest in 10.d4, as in mrjoker - Igor77, Internet Chess Club, 2008 (1-0, 70), guest2199 - guest401, Internet Chess Club, 2004 (1-0, 87) and MrJoker - Melbourne, Internet Chess Club, 2011 (1-0, 13).

I've varied with 10.0-0, as in perrypawnpusher - TJPOT, blitz, FICS, 2009 (1-0, 48) and perrypawnpusher - LeiCar, blitz, FICS, 2010 (1-0, 25). 

10...Be6

Possibly better was 10...c6, as in perrypawnpusher - pitrisko, blitz, FICS 2011 (1-0, 28), perrypawnpusher - HGBoone, blitz, FICS, 2011 (1-0,59) and MrJoker - ZICO, Internet Chess Club, 2012 (1-0, 34).

11.0-0 N8e7 12.f4 Bd7 

In this kind of position, I usually see things differently during the game than Houdini sees afterwards. I think "tactics" and play f4-f5, "kicking" Black's Knight, hoping to chase him to e5 when I can "kick" it again with d2-d4. Houdini "thinks" "position" and chooses d2-d4 instead, suggesting that Black respond to a later f4-f5 by withdrawing his Knight to g8.

13.f5 Ne5

In all fairness, had my opponent played 13...Nf8 here instead, I would have followed up with 14.d4.

14.d4 Nc4

My opponent prefers to play actively, but 14...N5c6 was probably better, with and edge to Black.

15.Qd3 b5 

I was pretty sure during the game that Houdini would want me now to play 16.a4, but I couldn't figure out what would be wrong with Black simply defending with 16...c6. After the game Houdini showed me 17.e5 dxe5 18.Ne4!? with a sharp attack - good for you, Readers, who figured that out!

I was unhappy with the possibility of 16.a4 b4 as well, although, again, after the game Houdini said "no worries" after 17.Nb5 Bxb5 18.axb5 and White will eventually capture the pawn at b4. Well, okay...

16.b3 Nb6

After the game Houdini again pointed out that if 16...b4, White would have the familiar 17.e5 dxe5 18.Ne4!? I think I would have answered 16...b4 with 17.bxc4 bxc3 18.Qxc3 and been happy with my broad pawn center.

17.Nxb5 

At this point my opponent seems to have disappeared, and Black forfeited on time. Quite likely, "life" intruded; I hope nothing bad. 

Instead, after 17...Bxb5 18.Qxb5+ Nd7 19.Bb2 White would have a comfortable game, with three pawns for his sacrificed piece, and possibly a small edge.

Outplayed

Although my opponent chose one of the stronger and more complicated defenses to the Jerome Gambit in the following game, I had my chance to level things out - but missed it. After that, I was simply out-played.

perrypawnpusher - HarlemKnight
blitz, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

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

7.Qf5+ Kd6 8.f4 Qh4+

The start of a complicated, but deadly counter-attack.

9.g3 Nf3+ 10.Kf1 

For some reason I played the text (also see "Repairing A Variation" Part 1, 2, 3 and 4), instead of 10.Kd1, with which I was 6-0, including 3 games that ended after 10...Qe7 11.Qd5 checkmate (perrypawnpusher - fortytwooz, blitz, FICS, 2010; perrypawnpusher - javistas, blitz, FICS, 2010; and perrypawnpusher - thinan, blitz, FICS, 2010).

10...Qf6

I don't think I'll ever be as lucky as to receive the mouse-slip 10...Qh3+ as in perrypawnpusher - rjbrigs, blitz, FICS, 2011, (1-0, 10) and perrypawnpusher - inasoy, blitz, FICS, 2014 (1-0, 51) again; although stranger things have happened.

On the other hand, 10...Nh2+ was good to me in perrypawnpusher - intssed, blitz, FICS, 2010 (1-0, 12), perrypawnpusher - JTIV, blitz, FICS, 2010 (1-0, 32), perrypawnpusher - mikelars, blitz, FICS, 2011, (1-0, 12) and perrypawnpusher - jgknight, blitz, FICS, 2011 (1-0, 68).

The retreat 10...Qh6, however, did not end so nicely for me, in the nonetheless enjoyable perrypawnpusher - Temmo, JG3 thematic, ChessWorld.net, 2008 (0-1,43)

11.Qd5+ Ke7 12.Qxc5+ Kd8 13.e5

Better was 13.Kg2 as in perrypawnpusher - james042665, Chess.com, 2008 (0-1, 18). 

13...Qf7 14.Kf2 b6 15.Qe3 Bb7 16.Nc3 Nh6 17.h3 Nxd2

Up until this point, Black has been doing very well, and I was surprised to discover later that he has no other games, as Black or White, in The Database. It was time to pour on the heat with 17...Nf5, or let the advanced Knight escape with 17...Ng5.

18.Rd1

Missing my one chance - and they were not coming by very often. With 18.Bxd2 Bxh1 19.Rxh1 White would have a pawn for the exchange, and the game would be a long way from being decided.

18...Nc4 19.Qd3 Qe6

The text is okay, but 19...Nxe5 would be crushing. Black does not need to sacrifice to win, however.

20.g4 g6 21.f5

The only way to stay in the game, according to Houdini, was to make a  play against the wayward Knight with 21.Nd5, although after the exchanges 21...Qxd5 22.Qxd5 Bxd5 23.Rxd5 White would be playing with one pawn for his sacrificed piece, and Black would not have to be in any hurry getting his pieces to better squares to press his attack.

21...gxf5 22.Bxh6 fxg4 23.hxg4 Nxe5 24.Qf5 

This blunder ended it all.

24...Nxg4+ White resigned

Natural Moves

The latest game from Bill Wall came with the following description: Here is a Jerome where my opponent tried to attack, but made errors, grabbed a pawn too greedily and lost a piece and the game.  I just played natural moves and waited for his mistakes.

Bill makes it all look simple.

Wall,B - Guest428245
PlayChess.com, 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.Qc3 

Sometimes - but not always, especially in Bill's games - the Queen goes to e3.

9...Nf6

Bill points out the alternatives 9...Qg5 and 9...Qh4, looking for counter attack. Black probably didn't want to repeat White's errors of moving his Queen too often.

10.d3 Kf7

10...Qe7 was seen in Wall,B - Guest4149739, PlayChess.com, 2013 (1-0, 30); while 10...c6 was seen in Wall,B - Boris, SparkChess.com, 2012 (1-0, 32). 

11.0-0

White decides not to go pawn hunting with 11.Qb3+ Be6 12.Qxb7 Qd7. "Natural moves" and all that.

11...Re8

Black continues to castle-by-hand, although Bill points out the alternative 11...b6. 

12.f4

Houdini slightly prefers 12.Qb3+ Kf8 and then 13.f4 but I am not sure why. It suggests that Black should answer 12.f4 with 12...Kg8, and after a few more moves play ...Kh8; so perhaps the suggestion of the White Queen check is designed to keep Black's King closer to the center, at f8.

12...c6

Bill recommends that Black finish "castling" with 12...Kg8.

13.Nd2 Ng4 

Black is thinking of counter attack, but, again, should have turned his thoughts toward 13...Kg8.

14.f5 Qb6+?!

Bill offers alternatives: 14...Ne7; 14...Nh8; 14...Nf8;14...Nh4 15.Nc4.

15.d4

I wouldn't be surprised to learn that Black simply overlooked this reply, expecting, instead, 15.Kh1? Nf2+ 16.Rxf2 Qxf2 17.fxg6+ Kxg6.

15...N6e5

Alternatives were 15...Ne7 16.Nc4 Qd8 17.Qg3; and 15...Nf8 16.Nc4 Qd8 17.Qg3. 

16.Kh1 Nf6?

17.dxe5 dxe5

As Bill points out, not 17...Rxe5? 18.Nc4. 

18.Nf3 Nxe4?

Black is a pawn down, but could continue to play with either 18...Qb5 19.Re1 a5 or 18...Qc7 19.Rd1. The text is a psychological slip along the lines of thinking White can't be better, now, can he, it's got to be an even game, and capturing the pawn will make it so...

I am reminded of the old Jerome Gambit saw: once White has equalized, he has the advantage.

19.Qc4+ Kf8 20.Qxe4 Black resigned

Updating the Semi-Italian Jerome Gambit

I have had a long-term interest in the Semi-Italian Jerome Gambit, so-called because it can arise from the move order - among others - 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 h6. (For example, see "A Jerome Look At The Semi-Italian Opening" Parts 1, 2, and 3).

More than a third (37%, actually) of the games in The Database with this move order were played by me, and I've scored 89% with the line.

I thought it was a good time to take another look at some recent games and update my knowledge.

ndrwgn - latang
standard, FICS, 2013

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

The Semi-Italian Opening.

4. O-O Bc5 5. Bxf7+

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 

I was surprised to see that Houdini 3 prefers this move to my choice, 7.Qh5+. I have played 7.d4 in only 3 of my 54 Semi-Italian Jerome Gambit games. Shows what I know.

7...Bxd4 

I wondered how often Black played 7...Qh4!? in this position, similar to 6...Qh4!? in the main line Jerome Gambit with 6.d4 (instead of 6.Qh5). It turns out that there is only one game example in The Database, HauntedKnight - keeper, blitz, FICS, 2012 (0-1, 26). This line deserves further exploration.

8.Qxd4 d6

There are 9 examples of ndrwgn playing this position in The Database, and he has scored 56%.

9.f4 c5 

"Meeting A Threat With A Threat", but 9...Nc6 was a more stable alternative. The text causes immediate difficulties. 

10.Qd5+ Be6 11.fxe5+ Ke8 12.Qxe6+ Ne7 13.exd6 Qb6 14.Qxe7 checkmate

One Game, Several Positions

I have chosen the following Jerome Gambit game to be illustrated by a series of diagrams. The first shows an opening oversight by both players - where White's Queen could have been won before move 10.

The remaining diagrams show the game after it has reached a pawns endgame. The computers say the first player has the advantage - but how does he win?

Black's drawing method is worth remembering.

ainafets - cmdeats
blitz, FICS, 2007

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6 8.0-0 

White slips, as covered in "Something To Watch Out For" and "Why Did He Play That Move?" - although Black overlooked his opportunity on the next move.

A game played 10 minutes after this one, on the same date, continued with the same tactical theme, only this time Black caught on: 8.f4 Nf3+ White resigned, ainafets - Papaflesas, FICS, 2007. 

Later on, the players reached the following position. White has recovered nicely, and reached a winnable endgame.

23.Kf2 Ke6 24.Kf3 Ke5 25.c3 a6 26.h4 h6 27.h3 g6 28.b3 c6

White is in no hurry, and slowly advances his pawns, avoiding anything drastic.

29.b4 c5 30.a3 h5 31.a4 d5 32.exd5 cxb4 33.cxb4 Kxd5 34.e4+ Kc4 35.b5 axb5 36.axb5 Kxb5 

The Queenside pawns have been exchanged off - maybe not the most efficient solution, but leaving much less for White to worry about. He still has a won game.

Houdini actually evaluates the position as a "checkmate in 18 moves" for White, but average players don't have to calculate that far to see a winning plan. The only "trick" is that the first player must realize that it needs to be his e-pawn that gets promoted.

37.Kf4 Kc5 38.Kg5 Kd4 39.Kxg6 Kxe4 40.Kxh5 Kf5

White has a 2-0 pawn advantage, but, due to the nature of those pawns - both Rook pawns - he now has only a draw. Instead, 38.Ke5, followed by shepherding the e-pawn to the 8th rank, was the way to go.

But - don't go away yet.

41.Kh6 Kf6 42.Kh5 Kf5 43.Kh6 Kf6 44.h5 Kf5

Having shown his opponent that he understands how to hold the draw - by keeping White's King trapped on the h-file in front of his pawns - Black suddenly has his King give way.

White now wins by springing his King with 45.Kg7.

45.h4 

Or, not.

45...Kf6 46.Kh7 Kf7 47.h6 Kf6 

Again, Black falters. (It was, after all, a blitz game.) Holding the draw was 47...Kf8.

48.h5 

And White, too, misses another chance to free his monarch. So the point gets split.

48...Kf7 49.Kh8 Kf8 50.Kh7 Kf7 51.Kh8 Kf8 52.h7 Kf7 53.h6 Kf8 Game drawn by stalemate

Don't, Here, Either

As a parallel to the previous post, I thought I would take another look at the Jerome Gambit Declined, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ and now 4...Kf8 or 4...Ke7. It seems overly generous for Black to decline a piece (and a possible offer of a second one), but sometimes defenders do not want to play a line - whatever its value - that the attackers want them to.

There are 245 games in The Database where Black declines the Jerome Gambit with 4...Kf8, with White scoring 56%. To break that down,  after the retreat 5.Bb3 (Houdini's choice), White scores 61%. The piece exchange, 5.Bxg8, has White score 57%. The complicating 5.Nxe5 scores 50% for White.

By comparison, there are 40 games in The Database where Black declines the Jerome Gambit with 4...Ke7, with White scoring a more encouraging 71%. Again, breaking that down, after the retreat 5.Bb3 (Houdini prefers the three retreats of 5.Bd5, 5.Bc4 and 5.Bb3), White scores 100%, as he does after the exchange 5.Bxg8. The complicating 5.Nxe5 scores 0%.

In summary, if Black does not take the Bishop in the Jerome Gambit, both computer analysis and game play suggest that White should either retreat it or exchange it, with good-to-very-good prospects.

Don't, Here

In the Blackburne Shilling Gambit, Black has high hopes that his third move will bamboozle White and lead to a killing attack. However, in the following game, Black's fourth move practically cedes the point. If this is a "Jedi Mind Trick", it is no match for a good blaster at your side...

sahistonline - aguisou
blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Ke7 

The Blackburne Shilling Jerome Gambit Declined.

A word to the wise defender: Don't.

In 475 games in The Database, White scores 70% 

For a good discussion of this Blackburne Shilling Jerome Gambit Declined see "Idées Fixes et Manqués",

5.Nxe5!? 

This complicating move appears in 201 games in The Database, where White scores 66%.

That is a good bit better than 5.Bd5, which appears in 10 games in The Database, where White scores only 50%. Half-way measures, it seems, score half the time.

"Best" according to Houdini, is 5.Bb3, which appears in a mere 14 games in The Database, where White scores "only" 68%. Perhaps the retreat is too "conservative" for many Jerome Gambiteers!

On the other hand, 5.Nxd4 appears in 78 games in The Database, where White scores 70%.

Alternately, 5.Bc4 appears in 32 games in The Database, where White scores 75%.

Finally, 5.Bxg8 appears in 102 games in The Database, where White scores 77%.

So, for White: hang onto your piece with 5.Bb3, or swap it off with 5.Bxg8; but you are by no means limited to these two good, contrasting, ideas. 

5...Nf6 6.Bc4 

White can tell his opponent what Al Capone said in "The Untouchables" - You got nothing.

6...d5 7.exd5 Nxd5 8.c3 Nf5 9.Qf3 White won by adjudication

I've had my problems in the past with adjudication at FICS (see "A Sneaky Way to Defeat the Jerome Gambit") but things look fine here. Down two pawns, with less development and an unsafe King, Black is finished. 

Professor Houdini (Part 2)

Here we continue the lessons from my last Jerome Gambit, a 2 12 blitz game. Tacticians are encouraged to follow along and discover what I and my opponent missed, and what Houdini later pointed out.

perrypawnpusher - ficshicks
blitz 2 12, FICS, 2014

Here I had just played 13.Nc4+, but, instead, after 13.Qc3!, Houdini rates White over a Rook ahead! 

analysis diagram



White is threatening mate, starting with Qb3+. Black can cover the checkmate square at b5, create "luft" (for his King or Bishop), as well as attack White's center with 13...c6 - if he needs to return a piece, this would make ...Nxd5 more do-able, allowing the Bishop to retreat along the a3-f8 diagonal.

White can then press on with 14.Be3+ Ka6 (if 14...Kc7 then 15.Nb5+ Kb8 16.Nxd6 with a two pawn advantage and an overwhelming position for White) 15.Nc4 Nxd5 16.exd5 Bf8 17.0-0-0. 

analysis diagram




While on the board White has one more pawn, Houdini rates the first player to be about a Queen ahead. I can not figure all that out, but it has to be due to all those undeveloped Black pieces! Mate or the win of a major piece is not yet apparent, but White clearly is better...

13...Kb5

Because of White's inaccuracy on the previous move (12.Nc4+ instead of 12.Qc3!), Black has the option of 13...Ka6 when after 14.Nxd6 cxd6 15.Qxd6+ b6 White has to make use of his 3 extra pawns against Black's extra piece, a relatively more difficult assignment.

14.a4+

A fitting cheapo - that works.

14...Kxc4

Once again, a6 is the safer square for the Black King to retreat to, when c3 would be the right square for the White Queen. It is hard not to point out that after 14...Ka6 15.Qc3 b6 (best) White would have the hilarious 16.Na5!?, when Black would have to find 16...c6 just to stave off - temporarily - disaster.

15.Qc3 checkmate

Professor Houdini (Part 1)

The other day I played a 2 12 blitz Jerome Gambit game, checkmating my opponent in 15 moves. A simple thing? Hardly. With the help of Houdini, afterwards, I discovered that my opponent and I had missed a whole lot.

perrypawnpusher - ficshicks
blitz 2 12, FICS, 2014

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Ne7

This is not Black's strongest defense.

An error by the defender, especially in an opening as sketchy as the Jerome Gambit, is a gift. The attacker should know what kind of gift that it is, and respond accordingly. In this case, it is important to realize that White can regain his sacrificed material, but that Black can find safety for his King.

9.Qxe5+

At this point, Black resigned in perrypawnpusher - ktonthat, blitz 10 5, FICS, 2009.

9...Kc6

Here, Black resigned in perrypawnpusher - Greystroke, blitz, FICS, 2012.

10.d4

I had forgotten that 10.Qc3 is the right move here, because a past opponent and I quickly left the path with 10...Qf8 11.d4 Qf6 12.Qxc5 checkmate, perrypawnpusher - nicolasalk, blitz, FICS, 2009.

Instead of expanding his pawn center, and dreaming of checkmate, White should think of pinning and winning the Black Bishop after 10...b6 11.b4 d6 12.d4 Kb7 13.bxc5 dxc5 14.dxc5 Nc6 when Black's King is safe, and White is ahead a couple of pawns.

Even at that point, White should modestly play 15.0-0, instead of grabbing more matrial with 15.cxb6 axb6 16.Qxg7 because of 16...Rg8 17.Qc3 Rxg2 when Black would be winning!

10...Bd6

Stronger was 10...d6, as in perrypawnpusher - vypux, blitz, FICS, 2009 (1-0, 20). In that game I was able to get away with 11.Qxg7  because my opponent missed 11...Nf5! 12.exf5 Qe8+ 13.Kd1 Bxf5 after which, if anything, Black would have an edge, despite his two-pawn deficit. Note that 14.dxc5? now would be crushed by  14...Qh5+ Instead White should try the sharp 14.d5+!? when Black would be prudent to reply 14...Kb6,

analysis diagram





with in an unclear position where White's King is in more danger than his counterpart, and Black's 2 Bishops and better Rooks give him the more threatening prospects. 

Also, 10...Bb4+ 11.Nc3 (11.c3 is better) appeared in perrypawnpusher - TheChessInnovator, blitz, FICS, 2008 (1-0, 43).

(Having played the line 5 times previously, and apparently having learned very little in the process, I am reminded of the Firesign Theater album, "Everything You Know Is Wrong"!) 

11.d5+ Kb5 

Safer was 11...Kb6 when after 12.Qc3 White has to develop and make threats against the enemy King while taking advantage of Black's trapped (thanks to the Knight on e7) Bishop. Black can, in some situations, consider returning his Knight instead with a well-timed ...Nxd5 followed by a Bishop retreat. Houdini puts White's advantage at less than a pawn, and shows no direct checkmates. 

12.Na3+

This move was based on the simple idea 12...Bxa3 13.bxa3 and then White will have the use of the b-file for a winning attack on the enemy King.

However, after the game Houdini pointed out that after 13...Ka6 there is no "winning attack on the enemy King" and that all White has left is 14.Qxg7 Rg8 15.Qd4 b6 (Not 15...Rxg2 right off because 16.Qa4+ Kb6 17.Rb1+ Kc5 18.Qb4#) 16.0-0 when Black's King escapes with 16...Kb7 and the game is about even.

Instead 12.Qd4 was the move to make, and then White's threats against Black's Bishop and King would give him the advantage, although it would still be a long time before the game would be decided.

12...Kb6 

As suggested above, 12...Ka6 would again leave White with little more than 13.Qxg7 when 13...b6, 13...Ng6 or 13...Re8 (followed by 14.0-0) all look about even. 

13.Nc4+ 

[to be continued]
