TRANSPOSITIONS!

When a new player begins chess openings, I recommend that whatever opening is chosen is one that the player will use every time! I want the player to become accustomed to the positions this opening leads into. My reasoning is that chess is learned in one of two ways:

First, we learn the placement of the pieces at the start of the game, then we learn the moves. Teaching chess by moves is not difficult, and learning the moves themselves is not difficult. This is what I think of as a scientific method. It is the way games are recorded.

But some players are blessed with a special talent; the ability to unify sensations into meaningful composites. They see the patterns, not the moves. This is more difficult to teach, it depends on the artistic or imaginative power of the player. This is what I think of as the Artistic method.

I believe it is necessary to begin with the first method, because there is lots of incidental learning that initially takes place, and because it can be digested by anyone. Starting with the artistic method would quickly discourage someone without the imaginative ability.

But, for those few who may have the talent for treating the game as an art, I believe that, as soon as the basics of the game are learned, the player can address pattern recognition. Instead of memorizing the moves in the opening, the player simply has pictures in his/her mind of the positions created by the opening, and plays to and from these positions.

If we know what we want from the opening in terms of these pictures, we can see the current picture and know whether we are on course, or whether we must change course to reach another familiar picture. If the performer can “see” the positions in his/her mind, a library of still pictures is created.

Of course, if the player insists on experimenting with a number of openings, the task can be much more difficult, or impossible. I believe it is easier to start with a solid “trunk” and add “branches” later. That’s why I stress the One Opening idea.

I offer this so that the reader can better understand the importance of playing by position, not by move. Pattern recognition is the key. If we were learning pattern recognition, we should start with pawn structures and build from that point. Pawn patterns are easy to recognize and often control the course of the game. The pawn structure is a key element in planning.

Patterns exist in opening, middle game and endings. However patterns are best learned in the endgame. There are known results- win/loss/draw- with endgame patterns. Think of an end game pattern as a “technique”. When an author says: “The rest is a matter of technique.” He is saying that this is a well-known endgame pattern.

Studying endgames is done with patterns, and the student normally has to repeat the move sequence a number of times before the “pictures” of the pattern form. When I began learning chess, I began with endgames. I needed a partner in order to have some fun working the endgame from a given position until mate, over and over, until it was memorized. Today, we have the computer as an opponent! We can test our understanding of the endgame pattern against the computer, which never tires of repetition!

This leads us to transpositions. Let’s look at transposing an opening. When we
are working to become expert in one opening, we may be able to play that opening with White only 20% of the time! That means we may need five games to get one where we can use “our” opening. (With Black, it gets easier; but I think that a White opening should be the first a player learns.) Fortunately, on Chessmaniac we can challenge with either Black or White and practice our white opening in every game where the opponent does not take us astray.

Now, if I am an inexperienced player and have put some time and effort into learning an opening, I have probably subconsciously developed a pattern recognition of this opening, which becomes greater, deeper and clearer as I continue to play this one opening. When this occurs, my win/loss ratio should improve; after all, my opponent is playing MY opening.

Now, in our opening, many transpositional possibilities may be seen. This is a game currently in progress on Chessmaniac, #6349512:

White Black
1. e4 e5
2. Nf3 Nc6. Black envisions a Berlin defense or a Two Knights, but there are many openings possible from these two opening moves.
3. d4 … White announces his preference: The Scotch Game.



3. … exd4.

This same position exists in the Scotch, in the Two Knights, in The Italian Game, in the Four Knights, and others.
4. Bc4 … This position exists in all the above openings, plus the Evans Gambit! (It is déjà vu all over again! – Yogi Berra)
4. … Nf6 Black prefers the Two Knights Defense and assays a transposition.



5. e5 d5 Still, this same position exists in all of the above openings, except that Black has ruled out the Evans Gambit.
6. Bb5 Ne4
7. Nxd4 Bc5 Now, this is also a position found in the Berlin Defense. So, we have a common position in the Scotch, the Two Knights, the Two Knights Defense, and The Berlin Defense.



8. Be3 Bd7 This position rules out all but the Scotch Game. White held to his opening of choice.

Voila! The Scotch Game! Here is the position that may have guided White:



White was expert in his opening, or Black could have taken the game into another opening.

Is it easier to memorize (mentally picture) the positions than to try to construct from the moves? Would you find it easier to memorize all of the first eight moves of all seven of these openings shown above, or would it be easier to remember not more than three significant positions? If you work from mental pictures of the position, you will see the possibilities from that position in the opening.

The endgame requires pattern recognition. If you aspire to Expert or Master status, it is essential to be able to recognize positions in the end game, even if you cannot do it well, yet, in the opening.

When you know your opening well, you can steer a transformation into a favorable position. Here is an opportunity seized in the early opening of game #6001387, on Gameknot:

White Black
1. e4 c4
2. d4 cxd4
3. c3 … The first three moves of the Morra Gambit.



3. … g6 The Morra declined. Black is transposing “out of the Morra” into a more familiar Sicilian, perhaps with the Dragon variation in mind.
4. cxd4 … Now, after … Bg7, White will have a familiar variation of the Alapin Sicilian.



Black has transformed into this Sicilian, although he may not have had the Alapin in mind.

In his book: *”The Chess Advantage in Black and White”, Larry Kaufman gives a sample of avoiding transpositions in the Semi-Slav defense. Here are some of his observations:
“The first decision for Black is whether to play … c6 or … e6 first.” “Playing … c6 first avoids the Catalan and the Marshall Gambit.” “Playing …e6 first avoids the Slav Exchange; as well as an early e3 without Nc3.”
Next, he shows how to avoid Black transpositions in the first four moves. Then, he shows the nine plausible move orders to reach the Semi-Slav. He explains that there are only four rules to follow to avoid the Queens Gambit Exchange version that favors White, to avoid allowing White to develop his bishop to g5 without paying a price, etc. By following his rules, you keep your opponent from transposing in this opening. You get to play your opening, not your opponents opening. I cannot show too much of the book without the permission of the author (Plagiarism). You’ll have to either get his book or look at my Black games where my opponent plays 1. e4, 1. c4, or 1. Nf3. You will find that some of my games are the Semi-Slav, where I instinctively follow Kaufman’s rules. Here is the starting position of the Semi-Slav:



A good exercise is to see if you can find the nine plausible ways of reaching this position. Here is the most direct route, where white has no preference beyond playing a queenside opening:

White Black
1. d4 d5
2. c4 e6
3. Nc3 c6
4. Nf3 Nf6

Now, let’s look at the first five moves of a game where I played Black, and White evidently had a move order, not a position, in mind. I will transpose into the Semi-Slav:

White Black
1. c4 … White seems to be trying for an English, or a Reti, or a Catalan.
1. … e6 We’re headed in White’s direction. Or are we?
2. Nf3 Nf6 White can still get his English or Catalan, but now we see the possibility that Black is playing for a Queen’s Indian.



3. d4 … The Catalan still looks OK, but now there is a hint of a Queens’ Gambit.
3. … d5 We now have a Queens Gambit Declined, but it could be a Ragozin variation, a Tartakower system, a Semi-Tarrash, an Orthodox, or even a Semi-Slav.
4. Nc3 c6 We have definitely transposed to a Semi-Slav!

(We have reached the same position by a different move order. Our moves were in concert with White’s moves, keeping him from [perhaps] his specific desired opening.)



The next moves were:
5. e3 Nbd7. And, suddenly White is playing Blacks’ Game!

When your opponent opens d4, c4, or Nf3; and you want a Semi-Slav, this is the picture you should have on the first move. Notice that if I wanted a Queens Indian, I could have played for that on the third move, or for a number of different Queen’s Gambits on the following moves. As you play, you will see yourself taken into strange territory a number of times. When you analyze the game afterward, look at the key positions and put the pictures you want in your head. Just be careful not to put in the pictures into your head that you DON’T want to create on the board!

I believe that players that move too quickly cannot get the pictures into their heads unless it is done in post-game analysis. I always analyze every loss, to try to find where I can improve.

*(In his book, Kaufman does not speak of transpositions directly, the book is basically his personal repertoire. He simply avoids transpositions in order to play his preferred openings.)

Next, I will offer some of my thoughts on Continuous Improvement.

Transposingly, Al (alfredjwood)
