A number of times I've indicated that White tends to gain an advantage in space in the Ruy Lopez. As always, opening study should be connected to the study of general chess themes. This is an extremely effecient way to improve our overall understanding of the game.

Let's make an in-depth introduction of the space advantage using the following common structure which can arise form the Ruy Lopez:

I should note that the properties of the structure would be essentially the same if Black had not yet played ...d6 - though this would tend to be an improvement for Black.

It's easy to see how this formation might occur. White has played a rapid d2-d4 (without first supporting it with c2-c3) and Black has responded with ...exd4 rapidly. Understanding this structure is critical for many reasons.

But before we connect it to any of our other learning goals, I'm going to take a moment to explain exactly what a space advantage is and how it functions in great detail. Beginners will benefits most of all from this analysis but if you think this is just for beginners, you're absolutely crazy. Taking a very basic look at some of the concepts we take for granted is always an extremely (perhaps necessary!) exercise. I engage in this kind of thinking all the time, even during battles with players of the highest standard.

Strictly speaking, a space advantage simply refers to the posession of more squares than our opponent. There are a few ways you can measure this. Before I introduce the more effecient ways I'm going to start with the simplest and most accurate so there's no question what a space advantage is. How do we do it? We simply count and compare the number of squares each side has under threat.

The first diagram is a position which contains our structure we're analyzing right now. In the second diagram I've merely circled all the squares which are under attack by a White piece. I simply went for square for square across the chessboard and asked "does a White piece attack this square?". If the answer was yes, I "counted" it. In this example White's pieces attack 41 squares. In the third diagram I underwent the same procedure for Black. Here the Black pieces attack only 32 squares. Thus we can conclude that White has an advantage in territory. We'll discuss how this information helps us in a moment, but for now we've identified one no-fail way of establishing who has control over more territory, or space. 

That was a little time consuming, but completely easy and also very instructive. If white's pieces have access to nine more squares than Black's, the implications are endless. His pieces have more squares on which to maneuver, and they bring a greater portion of the opponent's position under threat thereby minimizing his options.

Next, we'll look at shorcuts to help us assess who has a space advantage more quickly, and continue to explore what these means in terms of our strategy.

KEBU Opening Memorizer is quickly becoming the preferred method of doing the otherwise tedious work of memorizing your opening variations. I’ve created this article to take you step-by-step through the process of creating files to memorize and then using the software to seal the variations into your memory.

KEBU Opening Memorizer is a fantastic training software program for efficiently memorizing your openings. The first step to using the program is to create a PGN file with the opening variations you wish to memorize. Developing the file is relatively easy and can be done with a number of software programs. If you don’t own any software to create PGN files ChessBase Lite is a great place to start. It can be downloaded for free. There are countless other software programs that will assist you in creating PGN files. For the purposes of example I’ve used ChessBase 11.

Let us say that I wish to develop a repertoire against the move 1.e4. Through some research I’ve learned that the “French Defense” (beginning with 1…e6) is a relatively easy opening to learn and play, and I like the ideas – it seems to suit my style. I’ve read a book on the opening, but I want to remember the key variations so that I won’t be “caught out” in the opening.

Since White has a few different ways to respond to the French Defense, I’ll probably need to focus on one important response at a time as I learn the opening. White’s most popular reply is 1.e4 e6 2.d4 d5 3.Nc3 so I’ll start there – my first file will deal exclusively with how I plan to react against 3.Nc3.

Now using any of my materials: databases, chess engines, books, opening manuals – I develop a file which contains the most important ideas for my opponent and how I plan to respond to them. Here’s a screenshot:

(Don’t worry – I’ve attached a link where you can download this sample file right away!)

For each important option I found for White (using the database) I attached some line I’d like to learn for Black. Importantly, there’s no situation where I gave multiple ideas for Black  - the file just has all of the ideas I want to learn to play against, and then one single method of how to reply as Black.

Now I save the game as a PGN file (be careful not to save it in ChessBase format!).

Notice that I’m saving it as a PGN file! Click here to download the PGN file and take a look for yourself what I created.

Notice that I kept the file very simple. I think this is an important secret which I’ve written more about throughout this blog. You don’t need to make your files very complicated, you just want to be very confident about a smaller number of lines which, as a rule, don’t go too deep. Try it – and you’ll find that you’ll win a lot more games knowing a lot of basic lines as opposed to a few overly complicated lines.

Now there’s just one more step: getting these lines sealed in your memory! And here’s where KEBU Opening Memorizer comes in.

If you haven’t already done so please take a look at the following short video which in fact is a great introduction to how to memorize your files.

Best of luck with the openings software! We hope you find it to be truly enjoyable – but most importantly – we want you to win more games of chess!
