A Gambit for Halloween

October 29, 2020 by lefthandeddragon, posted in Balogh, chess, gambit, games, Opening, Uncategorized

You might not find it in a magazine. And you might not find it in a book. But there is a gambit that seems appropriate for Halloween. It is known as the Frankenstein-Dracula Variation (or FDV for short).

In this gambit (perhaps attack would be more descriptive), Black gives up a rook and a few pawns and then proceeds to gain control over a large portion of the board and threatens White’s queen in numerous ways.

Is it any good? Let’s check it (sorry, bad pun) out.

Happy H(a)unting!

Happy Birthday János Balogh!

September 10, 2020September 23, 2020 by lefthandeddragon, posted in Balogh, Birthday, correspondence, games, Uncategorized

Today is János Balogh birthday!

He was born on this day, Sept. 10 1892. And for those of you who might not know, Balogh is on of those rare players who excelled at both Over The Board (OTB) chess and Correspondence Chess (CC).

He won the Romanian Championship in 1930 and played in numerous Hungarian Championships. In addition, he played in the Olympiads for both of these countries.

His playing strength is hard to determine precisely as World War 2 interrupted much of his play. But he was likely of as least of IM strength and probably never received the IM title for two reasons. One that The International Federation of Chess (Fédération Internationale des Échecs, or FIDE for short) didn’t start awarding International titles until 1950 and around that time, Balogh started correspondence chess.

He was awarded the International Master of Correspondence title in 1953 by the International Correspondence Chess Federation (ICCF).

János Balogh was an expert in the openings as the following games show. He even had an opening named after him, although it is now considered unsound.

The Balogh Defense (also known as the Balogh Counter Gambit) is an unusual chess opening beginning with the moves:

1.e4 d6 2.d4 f5

Which would make a king pawn opening. The position, however, may also arise by transposition from the Staunton Gambit against the Dutch Defense, 1.d4 f5 2.e4!? (which would make it a queen pawn opening).

The main drawback to this opening, however it may be labeled is weak e6-square, with or without a black pawn on it.

Some noteworthy games.

DON’T ANSWER IT!

September 3, 2020September 4, 2020 by lefthandeddragon, posted in Blitz, games, Humor, Italian game, Uncategorized

There are at least two good reasons why cell phones are not allowed in tournaments.

One is that, with the readily available chess programs/engines and texting availability on almost all cell phones, text messages can be sent with computer engineered moves either from the computer or from a co-conspirator (such as “play 10.Rae1, idiot!).

Back around 1990 I was participating in an OTB tournament and had a cassette player with earphones and listening to some inspiring music. I easily won the game.

But immediately after the game my opponent strolled over to the tournament director (TD) and told him that he suspected I was cheating. He complained that I could be listening to pre-recoded moves coming from my cassette player. I looked at my former opponent, and gave him a look that very much suggested, “you’ve got to be kidding”.

In the presence of both the ex-opponent and the TD, I took out the cassette and showed it to the TD. The TD was satisfied about the label on the cassette and was about to rule in favor. But my ever suspicious opponent claimed I could have erased the content of the tape and replaced with my voice saying, “1.e4 e5 2.Nf3 ..”.

I put back the cassette in the player and showed the TD how to play it. He did so and briefly listened to The Grand Illusion album by Styx. The TD smiled and then handed back the player back to me. And while I walked away, cleared of any wrongdoing, I noticed the TD slowly shaking his head.

Now let’s go to the second reason why cell phones are not allowed in tournament halls. The game was played on-line as there is a nasty virus going around.

11…Nd6! [A more-or-less thematic move in this variation. It (temporarily) puts a stop to White’s plans and Black doesn’t mind giving back some material, as long as he stays ahead.

But let’s get back the game – I have yet to win the game.] 12.Qc2 O-O 13.Rxe4 Nxe4 14.Qxe4 Re8 (White has a lead in development for some material.

Then my caller asks me a question.)

29…Bh3? (Eek! Loss of concentration and loss of a free pawn and a tempo. Black has the better and obvious 29.Bxd5! I tell myself that at least I took some squares away from the knight, but I know that’s not the reason or issue. I had let my concentration drift again.) 30.Nc2 Bg2 31.Nb4 a5 32.Nc2 Bxd5 (Finally!

Thinking About Thinking

August 20, 2020August 20, 2020 by lefthandeddragon, posted in Book, Candidate moves, chess, games, Study, Thinking, Uncategorized

Sometimes I get the questions, “How do you plan your moves or know what moves to play?” Or “How do you determine candidate moves and figure out which one is best?” This is good start.

Well, there are times in which the moves are obvious and can be played very quickly.

Under this category are:

1) Book Moves – Opening moves that are considered standard, so you don’t have to think about them. For example, 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 represents the Nimzo-Indian Defence and is probably known by at least 90% of all players. The moves can be played quite quickly if both players want to get to that position.

2) Personal Preferences – Moves that a player has decided before the start of game he would like to play when facing a certain position. For example, in the King’s Gambit Accepted (1.e4 e5 2.f4 exf4), a player may have already decided he may go for the Bishop’s Gambit (3.Bc4), and can play that move instantly. A more experienced player might decide to come up with a new move in a certain position (also called Theoretical Novelty, or TN for short), and then play it to surprise his opponent.

3) Thematic Moves – It is well known that a rook belongs behind a pawn to assist in its promotion. Such thematic moves lessen the time in searching for the right move. Mostly used in speed games where time is limited.

If the moves are not obvious, then it is of great benefit to have a mental hierarchy of what constitutes a good, or even the best move in a certain position.

Here is my list:

1) Does my move, or a series of moves, produce or force a checkmate? If the answer is a yes, then there is no reason to consider anything else as a checkmate ends the game.

2) Does my move, or a series of a move, produce or force a material advantage?

Here is an example:

I read somewhere that winning a queen gives a player at least a 98% of winning the game. Winning a rook is at least 96%. Don’t ask me where I got this information, it was something I read a long time ago, but it does seem to be accurate. Maybe someone should do a more complete study here.

3) Does advancing a piece create problems for my opponent? For example, in the Fried Liver attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5?! 6.Nxf7!) White’s sixth move causes confusion in Black’s position and he has to focus on staying alive. It is also a Book Move.

4) Does pushing a pawn cause a similar effect?

5) How about on a board with less pieces? Does pushing a pawn increase the potential for queening? Best if a pawn move creates problems for my opponent and threaten to queen at the same time.

It is best to keep in mind that such moves are not played in isolation. The opponent has to make every other move. As such, one has to take into account that short of a forced mate, the opponent can, and usually will, be attacking as well. And one should also use the above list to check if his move, or series of moves, does not allow his opponent to counterattack with a more forceful move.

For example, if I make my move, does this allow my opponent to checkmate me? Can he win material if I was to make this certain move? Etc.

Suddenly, the planning gets complicated. One must now plan, studying, think, and sweat. And you are lucky, the best move, or at least a serious candidate move, will spring out from your labors.

Happy Birthday Fabiano Luigi Caruana!

Caruana was born this day in 1992 (July 30) in Miami, Florida. He moved to Italy in 2005 but returned to the United States when he moved to St. Louis, Missouri, in 2014.

He claims dual citizenship of Italy and the United States.

He played his first tournament at the young age of five at the Polgar Chess Center in the appropriately named in Queens borough in New York.

Caruana earned his grandmaster in 2007, at the age of 14 years, 11 months, and 20 days—the youngest grandmaster in the history of both Italy and the United States at the time.

He won the Italian National Championship in 2007, 2008, 2010, and 2011 and the US Championship in 2016.

He is the third American to play in the (OTB) World Championship (after Marshall and Fischer), losing the playoff to Magnus Carlsen after drawing the match 6–6 (2018).

Here are some games from the amazing GM.

From England, with Love

June 25, 2020July 15, 2020 by lefthandeddragon, posted in Bird, From, gambit, games, Opening, Uncategorized

Martin Severin From (Apr. 8 1828-May 6 1895), an English player, came up with an intriguing gambit to deal with Bird’s opening (1.f4). It has proven to be so popular that it now the most common response to 1.f4 and is played in blitz chess, OTB games, and correspondence games.

But why this gambit so popular after 150 years? For one, it can lead to a quick mate for Black. Second, even if the game does not end in a quick mate, the initiative can quickly pass to Black. And all for the price of a pawn.

Many players have studied From’s Gambit and contributed to the it’s theory. It’s a labor of love, and because it’s chess, it is a complicated and forever friendship. Some players actually do fall in love with this opening.

Here is one of the earliest games played by it’s creator.

Let’s look at some problems and early traps that can trouble and entrap White.

1.f4 e5

[White does not need to accept the offered pawn. He can play 2.f4 and the game is now a King’s Gambit. Which is another opening White having to learn. In any case, he is no longer playing a Bird’s. Or he can attempt other moves. But declining the gambit, unless it’s 2.f4, usually backfires.

3.exd6 Bxd6

[White now has a pawn but the pressure on his kingside is enormous. He can lose instantly with 4.h3?? Bg3#. He can also try the much stronger move, 4.d4. But even then, he has some problems.

So he, White, has to try 4.Nf3.]

4.Nf3

[Now Black has a couple of very popular choices; 4…g5 (an aggressive attacking move) and 4…Nf6 (a more secure move, securing some initiative, but allowing White to breathe a little).

Just in case you were interested in the other moves, here are few more.

Now let’s take a look at 4…g5!?. Obviously the pawn wants to advance to g4, driving the knight away so the queen can come to h4, giving check and creating a mess of White’s position.

White must do something about this threat.
5.e4 does not work.

Chess and Checkers

June 18, 2020 by lefthandeddragon, posted in Castling, chess, games, Uncategorized

When I was in High School, and just beginning to understand the theories of chess, an old man came to visit us at the table. This episode probably then happened a park.

He watched with some intensity, as I and my opponent were engrossed in our game. After the game ended (I think I won), he asked, almost with a sneer, “so what is the difference between checkers and chess?”

I didn’t exactly why he was asking this question. But I gave him my best answer and replied, “Chess is more complicated”.

With that, the old turned around and departed. Maybe he thought I was rude and me being a male teenager, that may be true. Or is because he didn’t expect the conversation to go that way. Or he may have thought he has interacting with younger teens (after all, when I was 14 I could still pass for a 12 year-old).

So, I got to thinking, what are differences between chess and checkers. And I drew up a list. Which I promptly lost. But I remember most of it. And now with the magic of the Internet, and blogging in particular, here is my list (corrected for spelling and grammar).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

WHAT IS THE SAME

The boards are identical in size (8 x 8).

Each board has 64 squares.

A man moving to the 8th rank is promoted.

MakingChessComputer1

It is a game usually played by only two competitors.

WHAT IS DIFFERENT

Checkers is played on a red and black board. Chess is typically played on a white and black board.

In checkers, each player starts with only 12 men. In chess, each player starts with 16 men.

checkers

In checkers, all the men look the same, move the same way, and are of equal value. In chess, the pieces look different, move differently, and are worth different values.

pawns-3467512_960_720

In checkers, Black moves first. In chess, White moves first.

In checkers, a man reaching the 8th rank can only be promoted to a King. In chess, a man reaching the 8th rank can be promoted to a Queen, a Rook, a Bishop, or a Knight. But never to a King.

In checkers, players use only 32 squares of the board. In chess, both players use all 64 squares.

In checkers, players may only move their men diagonally. In chess, players may move their pieces diagonally, forward, backwards, and horizontally.

In checkers, a player captures a man by jumping over them. In chess, a player can capture a man by occupying their place on the board.

In checkers, only a king can move backwards. In chess, Knights, Bishops, Rooks, Queens, and Kings can move backwards. Pawns are the only units that may only move forward.

maxresdefault

In chess, there are rules for en passant and castling. No such rules exist for checkers.

In checkers, captures are mandatory. In chess, players may decline a capture.

In checkers, openings are decided by lot. In chess, opening play is determined by the players.

And for us chess enthusiasts:

Chess has a high cultural value. People equate us chess players as possessing great intelligence, a fantastic memory, and in its purest form; grace.

It is possible to be a prodigy in math, music, or chess.

Two examples;

Frank Brady wrote “Bobby Fischer: Profile of a Prodigy”.

Wikipedia has an article titled, “Chess Prodigy”.

No checkers player has ever been known or labeled as a prodigy.

Dallying with the Dilworth

June 11, 2020 by lefthandeddragon, posted in chess, gambit, game, games, Opening, Ruy Lopez, Uncategorized

Recently I had an opportunity to analyze to the Dilworth variation of the Open Ruy Lopez.

To begin, let us look up the moves that lead up the Dilworth.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 (This move defines the Ruy Lopez, named after the 16th-century Spanish priest Ruy López de Segura.) 4.Ba4 Nf6 5.O-O Nxe4 (The Open Variation of the RL. Black’s objective is to get good piece play by advancing his d-pawn and giving his pieces the freedom to roam across the board as well as pushing and protecting his d-pawn.) 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.c3 (9.Nbd2 Nc5 10.c3 d4 11.Ng5 leads to interesting Karpov Gambit. I’ve researched this line and IMHO, White’s attack is almost worth the pawn he sacrificed.) 9…Bc5 (Black can also play 9…Be7, which will give him a more closed game.) 10.Nbd2 O-O 11.Bc2 Nxf2!? (With this move Black gives up a knight for White’s f2-pawn and in return, gets a pinned White Rook and misplaced White King. And the Dilworth fight is on!) 12.Rxf2 (A forced move. The real analysis begins here.)

Black can certainly play 12…Bxf2+ at this point. But better is delaying this capture as not only is rook pinned, but it’s fixed position temporarily hinders the movement of White’s pieces.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.c3 Bc5 10.Nbd2 O-O 11.Bc2 Nxf2 12.Rxf2 Bxf2+ 13.Kxf2 f6 14.exf6 Qxf6 15.Kg1 Rae8!? (15…Bg4 16.Nf1 Bxf3 17.Qxf3 Qxf3 18.gxf3 Rxf3 19.Be3 Ne7 20.Bg5! +/- ECO.) 16.Nf1 Ne5 17.Ne3 Nxf3+ 18.Qxf3 Qxf3 19.gxf3 Rxf3 20.Bd1 Rf7 1/2-1/2

Black must play 12…f6, or at least transpose into it.

We now continue.

12.Rxf2 f6

Two moves White should now avoid are 13.Nb3 and 13.Qe2. Again, not necessarily bad, but he has a better alternative.

13.exf6! And now Black has to play 13…Qxf6 or 13…Bxf2+ .

We’ll look at 13…Qxf6 first.

White’s best is 14.Nb3! He wins most of the games as his knight move solidifies his position.

White also can experiment with: 14.Qf1.

So Black almost has to play 13…Bxf2+ and come up with a plan after 14.Kxf2

He can try 14… fxe5!?

But more common is 14…Qxf6.

White can go totally wrong after 15.Kg1

But 15.Kf1 Ne5 keeps the game going. It is doubled-edged and White just has to find the correct 16th move. He didn’t in this game.

Today is Andy Soltis’ birthday!

Born on May 28, 1947 in Hazleton, Pennsylvania, his contributions to chess has been enormous.

For those of you might have been hiding under a rock since 1980, he’s a prolific author, frequent contributor to Chess Life, and even made into the world’s elite of chess, earning his IM title in 1974 followed by a GM title in 1980.

Let’s go over some of his games first.

But White has more space which translates into greater coordination, mobility and freedom for his pieces. That is more than enough for White to have the advantage.) 10…Bd7 11.Qe1 O-O 12.Qg3 Rab8 13.Kh1 Kh8 14.Bf3 g6 15.Nxc6 bxc6 16.e5 Ne8 17.Ne4 d5 18.Ng5 Rxb2 19.Qh4 Bxg5 20.Qxg5 Ng7 21.Bc5 Re8 22.Be7 Kg8 23.Bf6 Reb8 24.Bg4 Ne8 25.Be7 Qc8 26.Ra3 Rb1 27.Bd1 a5 28.Qh6 Ng7 29.Rh3! 1-0

7…Nh6 8.Bb5 O-O 9.O-O Nf5 10.Nc3 Bd7 11.Nxd5 Nxe5! 12.dxe5 [Or 12.Bxd7 Nxf3+ 13.Qxf3 Qxd7 14.Be3 Rfd8 15.Nc3 Nxd4 16.Bxd4 Bxd4 17.Rad1 Qc6 18.Qxc6 bxc6 19.Rfe1 e5 20.Rc1 (-1.39 Stockfish)] 12…dxe5 Bxb5 13.Re1 Bc6 14.Nb4 Qxd1 15.Rxd1 Bxf3 16.gxf3 Bxe5 -+ 17.Rd5 Bd6 18.Bd2 Rfd8 19.Bc3 a5 20.Rxd6 Rxd6 21.Nc2 b6 22.Kg2 Rad8 23.Ne3 Nxe3+ 24.fxe3 Rd1 25.Rxd1 Rxd1 26.Kf2 f6 27.f4 Kf7 28.Kf3 Ke6 29.Bd4 b5 30.a3 Rf1+ 31.Kg2 Rb1 32.Kf3 Kd5 33.Bc3 a4! 0-1 (White can’t stop the Black king from entering on the queenside.)

Soltis didn’t confine himself to merely playing the game. An important variation in the Sicilian Dragon was named after him.

Let’s review the opening moves.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 (The main line in the Dragon. White usually castles queenside and attempts to storm Black’s castled kingside with his pawns and follow up with pieces. Sacrifices are common threats for both sides.) 6.Be3 Bg7 7.f3 O-O 8.Qd2 Nc6 9.Bc4 Bd7 10.O-O-O Rc8 11.Bb3 Ne5 12.h4 (White has played this move to maintain and continue his threats of opening Black’s kingside. Experience has shown that Black usually ends up on the losing side if he allows White’s h-pawn to continue his advancement. So…) 12…h5!?

(Now White’s h-pawn is stopped. Does this mean Black is going to win? Not necessarily. Does it mean White is going to win? Not necessarily either. But it does mean White has to look for other way to infiltrate the kingside.)

Here is the inauguration of this variation.

Barczay-Soltis
Reggio Emilia
Italy, Jan. 1 1971
1.e4 c5 2.Nf3 d6 3.Nc3 Nc6 4.d4 cxd4 5.Nxd4 g6 6.Be3 Bg7 7.Qd2 Nf6 8.f3 O-O 9.Bc4 Bd7 10.Bb3 Rc8 11.h4 h5 12.O-O-O Ne5 13.Bg5 Nh7 14.Bh6 Bxh6 15.Qxh6 Rxc3 16.bxc3 Qa5 17.Kb1 Qxc3 18.Qd2 Qc5 19.Ne2 a5 20.Qd4 Qc7 21.Nc3 Nf6 22.a4 Rc8 23.Kb2 Be6 24.Rhe1 Kg7 25.f4 Nc6 26.Qd2 Nb4 27.Re3 Qb6 28.Qd4 Rc5 29.e5 dxe5 30.fxe5 Ng4 0-1

A good way to start off the New Year!

Here are two other games worthy of study.

S. Hwemp (2280)-K.D. Mueller (2445)
corres.
ICCF, 6/7 Cup, ½ Finals, 1990/1

IM Alexander Khalifman (2530)-Stanislav Savchenko (2480)
USSR Ch.
Simferopol, Ukraine, 1988
[Don’t fret about the titles. Both players earned their GM titles a few years later; Khalifman in 1990 and Savchenko in 1993.]
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 O-O 9.Bc4 Bd7 10.h4 Ne5 11.Bb3 h5 12.O-O-O Rc8 13.Bh6 Bxh6 14.Qxh6 Rxc3 15.bxc3 Qc7 16.Kb1 Rc8 17.g4 a5 18.gxh5 a4 19.Bd5 Nxd5 20.exd5 Qxc3 21.hxg6 fxg6 22.Rhg1 Bf5 23.Nxf5 Qxc2+

(A situation in which neither Black nor White can win. But they both can lose. A draw is best for both players.) 1/2-1/2

GM Soltis also promoted another, lesser-known, variation, in the Sicilian. Entitled the “Chameleon Sicilian” it runs as:

1.e4 c5 2.Ne2!?

The point being it is impossible for Black to know what White is attempting to do. White can play the Closed Sicilian with 3.d3, 4.g3 and 5.Bg2. Or he can open the game up with: .d4 cxd4 .Nxd4 at any time. It’s especially troublesome for Dragon addicts.

~~~~~~~~~~~~~~~~~~~~~~~

Andy Soltis has written a weekly chess column for the New York Post since 1972 and a monthly column (“Chess to Enjoy”) for Chess Life since 1979.

In addition to his weekly and monthly columns, he has written several books including; The Best Chess Games of Boris Spassky (1973), Pawn Structure Chess (1976), Chess to Enjoy (1978), Karl Marx Plays Chess : And Other Reports on the World’s Oldest Game (1991), Soviet Chess 1917–1991 (1999), Bobby Fischer Rediscovered (2003), and many others.

His books are a mixture of games, analysis, and fresh observations on the opening and other aspects of play. His column, “Chess to Enjoy”, covers historical viewpoints, human interest stories, computer analysis (and sometimes their failings), and literary perspectives. He is known to use humor to illustrate important points.

For his chess writings, he was named “Chess Journalist of the Year” in 1988 and 2002 by the Chess Journalists of America.

Happy Birthday Andy Soltis!!

Secret Games of Botvinnik vs. Averbakh

May 21, 2020May 21, 2020 by lefthandeddragon, posted in Botvinnik, games, history, Uncategorized

During his playing career Botvinnik battled played a number of players who were of GM strength in secret matches. They were all played in the USSR, and were meant to prepare him for Olympiads, important tournaments, and matches with Western (i.e., non-Warsaw Pact) players.

They were played in secret so Botvinnik could experiment with different openings, and of course to keep any loses away from prying Western eyes.

His most common match player during the 1950s was GM Averbakh.

As he put it, “As a sparring partner, I evidently suited Botvinnik, and over the next two years we played about 25 training games. The time control was the standard one of two and a half hours for 40 moves. If a game remained unfinished, it was not normally resumed.”

Here are four of those secret games.

~~~~~~~~~~~~~~~~~~~~~~~

GM Botvinnik-GM Averbakh
Training Game
Moscow, Oct. 1955
[By the mid-1950s, Averbakh was considered an expert in the endgame. But here, he never gets to the endgame!]
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 O-O 9.g4 Nxd4 10.Bxd4 Qa5 11.h4 Be6 12.h5 Rfd8 13.hxg6 hxg6 14.a3 d5 15.e5 Nd7 16.Qh2 Nf8 17.Bd3 f6 18.exf6 exf6 (White has the advantage and can win a number of ways. He chooses the most direct route.)

19.b4! (Trapping the queen.) 1-0

GM Botvinnik-GM Averbakh
Training Game, June 6 1955
[E56]
[With everything else being equal, a passed pawn is worth more than a pawn.]
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 O-O 5.Bd3 d5 6.Nf3 c5 7.O-O Nc6 8.a3 (8.Qc2 is also good.) 8…Ba5 9.cxd5 exd5 10.dxc5 Bxc3 11.bxc3 Bg4 12.c4 Ne5 13.cxd5 Nxf3+ 14.gxf3 Bh3 15.e4! (White is willing to give up the exchange for a powerful, mobile pawn center.) 15…Nd7

[So why can’t Black take advantage of the exchange sacrifice?

Here is one answer:

The text game provides another answer.]

[White has two good choices here; 12.Bd2 (ECO’s line), and 12.Bb2, which seems to be a Botvinnik TN.] 12…Nc6 13.Nf3 f5 14.Qc2 d6 15.Re1 dxe5 16.Nxe5 Nf6 17.h3 Qc5 18.g4 Ne4 19.Nxc6 Qxc6

20.Rg1! (White’s next moves are designed to open the diagonals for his bishops by eliminating the center pawns.) 20…Rf7 21.Re3 Qc5?! (21….Kf8 might seem anti-thematic, and perhaps even a little bizarre, but it’s important to get out of the soon-to-opened g-file.) 22.gxf5 exf5 23.Bxe4 fxe4 24.Qc3 1-0

GM Botvinnik-GM Yuri Averbakh
Training Game, 1956

1.e4 e5 2.Nf3 Nc6 3.Bb5 f5 4.Nc3 fxe4 5.Nxe4 Be7 6.Bxc6 dxc6 7.d3 Nf6 8.Qe2 [Botvinnik has what he wants; a few small advantages (in this case, space and positional) he can take to the endgame.] 8…Bg4 9.h3 Bxf3 10.Qxf3 Qd5 11.Bg5

[Also good is 11.O-O O-O 12.Be3 Rad8 13.b3 b6 14.Rad1 Qd7 15.Nxf6+ Rxf6 16.Qg4 Qd5 17.Qe4 Rg6 18.Kh1 Re8 19.f3 Rf8 20.Bg1 Bd6 21.Rde1 Re8 22.Re2 Rg5 23.Bh2 Rh5 24.Rfe1 Qa5 25.Qxc6 1-0, E. Szalanczy (2237)-M. Lyell (2225), First Saturday, Budapest, Sept. 4 2012.]

11…Nxe4 12.dxe4 Qf7 13.Qxf7+ Kxf7 14.Be3 Ke6 (Black’s king travels to the center to contest the center squares.) 15.Ke2
2020_05_21_D

(White’s advantages are now easier to perceive. One is that two of Black’s queenside pawns are doubled. A bigger problem is that his e5-pawn is isolated. Finally, White’s bishop has more freedom of movement than Black’s. Black’s biggest plus is his strongly placed king on e6.)

15…Rhf8

[Black can also try 15…Rad8. After 16.Rad1 (not 16.Bxa7? b6!) 16…Rd6 17.Rxd6+ cxd6 18.a4 (Again, not 18.Bxa7? due to 18… a8). Stockfish prefers 15…Rad8 16.h4 h5 17.g3 Rd7 18.a4 g6 19.Rag1 a6 20.Ra1 Rhd8 21.f3 Rf8 22.Rhg1 Rdd8 23.Rgb1 Rf7 or even the more immediate 15….h5 16.h4 a6 17.g3 Rad8 18.a4 a5 19.Rag1 g6 20.Rc1 Rhf8 21.Ra1 Rh8 22.Rag1 b6 23.f3 Rhf8. Verdict: White has definite, and annoying (for Black), advantages. The big question is: “Can White win?” The answer is: “Probably yes, especially if you are a GM”.]

16.h4 Rf7 17.h5 h6 18.Rh3 Bg5 19.Rd1 Raf8 20.f3 a5 21.Rg3 Kf6 22.Rg4 a4 23.g3 Ke6 24.Rf1 Bxe3 25.Kxe3 Rd7 26.f4 Rf6 27.Rg6 Kf7 28.fxe5 Rxf1 29.e6+ Ke7 30.exd7 1-0

[30….Kxd7 31.Rxg7+ Kd6 (31…Kd8 is passive. White will eventually win by slowly, surely, and simply moving up the board. Black’s only chance to bring his king up and challenge White for control of the board. But White still wins.) 32.Rg6+ Ke5 33.Rxh6 Rc1 34.Rh8.]
