Space, Time and Material

    
One of the first instructional books I read was The Middlegame in Chess by Eugene Znosko-Borovsky (1884–1954). Little known as a writer, Znosko-Borovsky was a Russian master and highly regarded author who was known for his instructional books. He had a knack for explaining things in an easy to understand way. In the book he discussed how to evaluate middlegame positions based on space, time and force (i.e. material). Another book that addresses these same elements, but also covers a lot more subjects, is Ludek Pachman’s The Opening Game in Chess. 
    These basic elements play a large part in the opening. Time, that is piece development and the gain or loss of a tempo, and the struggle for the center and the attempt to gain space to maneuver the pieces are, or should be, familiar. 
    The other element, material, can be hard to assess because the amount is important, but sometimes other factors must be considered. e.g. in some positions a Knight might be more valuable than a Rook. And, another example is in the opening when material may be sacrificed to gain time or space.
    Today’s game is a good illustration of the elements. The game was played in the Hastings tournament in 1895. This tournament was the strongest ever held up to that time. 
    Steinitz’ opponent was Curt von Bardeleben (1861-1924) of Germany. According to Chess metrics in 1895 he was one of the top ten best players in the world. On January 31, 1924, at the age of 62, after plunging from an apartment window in Berlin. Some sources say it was suicide, others an accident. 
    The suicide theory suggest it was triggered by financial troubles he experienced. He was supposedly living in povery at the time having lost his fortune during World War I. 
    Jacques Mieses and Bernhard Kagan, two of his contemporaries, believed it was accidental. In an obituary, Kagan suggested that Bardeleben suffered from severe arteriosclerosis and might have had a dizzy spell while leaning out an open window and lost his balance. Kagan’s theory is possible. Feeling dizzy, losing coordination have a difficult time walking and unexpectedly fall down are some of the symptoms of arteriosclerosis.
 

     In this game von Bardeleben avoids a lot of pitfalls by not taking a second gambit Pawn when it was offered at move 7. However, he was under some pressure after having taken the first gambit Pawn because Steinitz had more space and piece activity. von Bardeleben’s real mistake came when he played 16...c6 which made it impossible to complete his development even though the material was greatly reduced. Had he played 16...Kf7! it would have connected his Rooks and resulted in complete equality. This brings to mind the statement by one of the game's really great teachers, C.J.S. Purdy, who reminded his students that development is not really complete until the Rooks are connected.
 

A game that I liked (Fritz 17)

First, notice that white has an isolated d-Pawn...it could become a liability in the ending. Howver, at the moment black has the immediate problem of countering white's pressure on the e-file.
