Such an idea reveals hidden aspects of the position which had escaped with a vision less accurate (Chess Terminology).

    - Imb -


  • «Imbalance» :

  • Imbalance: Any difference between the White and Black positions. Material advantage, superior pawn structure, superior minor piece, space, development and the initiative are all typical imbalances (Chess Terminology - see: www.JeremySilman.com).

    - Inact -


  • «Inactive piece» :

  • Inactive piece: A piece not directly involved in the flow of the game (Chess Terminology - see: Rob McDonell, ARK ANGLES. All Rights Reserved).

  • «Initiative» INIT:

  • The Initiative is undoubtedly the fundamental key of the success in a Chess game. It means that a camp (that which has the initiative) is more or less able to impose his will on the other.

    This notion has been introduce by Capablanca and closely studied by Richard Reti. One obtains the initiative as follows:
  • By accelerating the development, at the beginning of the game, to arrive to an advance of development.
  • By sacrificing material to open lines and to save times of development.
  • While playing vigorously. In other words by making the choice of Initiative Moves.


  • In addition we will show in next chapters of our New Chess Theory (NCT:) Lecture that Initiative and Spectrum (SPCT:) are two fundamental concepts strongly conneted. (Current Chess Theory & New Chess Theory).

  • «Initiative Move» INIM:

  • Richard Reti opposes clearly both terms: Development & Initiative; an Initiative Move is very often a development move in the classical meaning. But moreover, it is precisely a move holding account of the position and dictated by the objectives that one assigned taking justly into account this position.

    One can thus recommend to any player to make as much as possible the choice of initiative moves and to connect such ones... Again this is the best way to make durable the initiative.

    Now it is useful to add that an initiative Move is playable at any state of a chess game, from the opening to the endgame!... It is intentionally that we choice two example of initiative moves; the first one intervening during the theoretical opening and the second one in the deep middle game. We consider first the A43-Pivot Game:

       Kluger, Gyula - Tal, Mihail [A43-r4*] Kislovodsk, 1964 - Chess-Theory Analyzed Game No 059 .


    After:

    1.d5 d6 2.Nc3 g6 3.Nf3 Bg7 4.Nf3 Bg7 5.e4



    we recognize the "Old Benoni Center". The game go on this way:

    5...Nf6 6.Be2 Na6 7.0-0 Nc7 8.a4 0-0 9.Bf4 b6 10.h3 Bb7 11.Re1 Re8 12.Bc4



    This time you reach the Kluger-Tal Variation, Main Line. ECB (ECO Codes Base) Classification [A43-r4*]. And now:

    12...a6 13.Qd3 Nd7 14.e5!?



    Obviously this last move is first of all a Break Move (BREM:). But it is also, without any doubt, an Initiative Move; it is active and clearly integrated to the Tal's plan.

    Now let us see the game:

       Williams, Elijah - Stauton, Howard [A43-w] London knockout playoff -3pl London (7), 1851 - Chess-Theory Analyzed Game No 052 .


    After the beginning:

    1.e4 e6 2.d4 c5 3.d5 exd5 4.exd5 d6 5.c4 Bf5 6.Bd3 Bxd3 7.Qxd3 Nf6 8.Nc3 Be7 9.Nf3 0-0 10.0-0 Nbd7



    we are, in 1851 (when this game was played!), in the Deep Middle Game (DPG:) and Stauton finds the interesting answer:

    11.Qf5!?



    It is an Initiative Move played with respect to the Stauton's Plan (PLAN:). Moreover, the White's Queen may now coordinate the White action on the Kingside.

    (Current Chess Theory & New Chess Theory).

  • «White (Black) Initiative» WINI: (BINI:)

  • We will study, through our lectures and evidently many Chess-Theory's analysis, various example of White (Black) Initiative (Chess Practive).

  • «Strong Initiative» STIN:

  • A Strong Initiative of one side happens usually in Quick Divergence Games (QDGA:).

    (NCT & DCC - "Dynamic Chess Classification").

  • «White (Black) Strong Initiative» WSIN: (BSIN:)

  • We will study, through our lectures and evidently many Chess-Theory's analysis, various example of White (Black) Strong Initiative (Chess Practice).

  • «Inner File» INFI:

  • A Inner File is a i-file, where i=b, c, d, e, f, g (Chess Terminology - NCT II - "Chessboard geometry").

  • «Inner Zone» INZO:

  • The Inner Zone is the union of all inner files b, c, d, e, f, g:

    INZ= set of all (i,j)-squares: i=b, c, d, e, f, g & j= 1, 2, ..., 8



    (Chess Terminology - NCT II - "Chessboard geometry").

  • «Inner Pawn» :

  • Inner Pawn: An Hans Kmoch's term signifying a pawn belonging to the inner zone; i.e. on one of the files b, c, d, e, f, g (Modern Chess Theory - Hans Kmoch's Terminology).

  • «Inner Lever» :

  • Inner Lever: An Hans Kmoch's expression signifying a lever where the capture would move toward the center (Modern Chess Theory - Hans Kmoch's Terminology).

  • «Inner Swap» :

  • Inner Swap: A capture towards the center that produces a double pawn (Modern Chess Theory - Hans Kmoch's Terminology).

  • «Innovation» :

  • Innovation: A new move in an established position or opening (Chess Practice).

  • «Insufficient material» :

  • Insufficient material: When neither player has enough pieces to mate their opponent; then a draw is declared (Chess Practice).

    - Int -


  • «Interior»:

  • An Interior square (of the chessboard) is a square surrounded by other squares. The set of all interior squares is said the Interior of the chessboard (NTC II - "Chessboard Geometry").

  • «Intermediate Move» INTM:

  • An Intermediate Move is a move linking together two Moves or more generally two Move Sequences; for example an intermediaite move may occurs between two check series. Let us notice that an intermediate move is also very often a Priming Move (PRIM:) (Chess Terminology - NCT VI - "Chess move classification").

  • «Intermediate Combination» INTC:

  • An Intermediate Combination is a combination linking together two Moves or more generally two Move Sequences. Let us notice that an intermediate combination is also very often a Priming Combination (PRIC:) (Chess Terminology).

  • «Intermediate Check» INTK:

  • An Intermediate Check is an intermediate move constituted by a check move (Chess Terminology).

  • «Internet Chess Server» :

  • Internet Chess Server: Any computer that enables live chess play between remote (usually) players, and is connected to the Internet (Chess Practice - see: Logical Chess - Glossary of Chess Terminology).

  • «Interpose» :

  • Interpose: Placement of a piece between an attacking enemy Queen, Rook or Bishop, and the piece being attacked (Chess Theory).

  • «Interspan» :

  • Interspan: In Hans Kmoch's vocabulary, the distance between two opposing pawns (Modern Chess Theory - Hans Kmoch's Terminology).

  • «Intuitive» :

  • Intuitive: Usually a sign of experience, it enables a player to choose a move or plan by feel or common sense as opposed to detailed analysis (Chess Practice - see: www.JeremySilman.com).

    - Isolat -


  • «Isolated Pawn» ISPA:

  • An Isolated Pawn is a pawn that cannot be protected by pawns on its flanks, because there is any friend pawn on the both adjacent files. Such a pawn is often considered like a weakness, but it is not always the case. One finds an example of isolated pawn in the game:

       Houska, Miroslav (2200) - Prie, Eric [D00-r13*] Paris-London, London (9), 1994 - Chess-Theory Analyzed Game No 037 .


    Let us observe first the position getting after :

    1.d4 d5 2.Bg5 f6!? 3.Bh4 Nh6! 4.f3 c5 5.c3 Qb6 6.Qd2 e6 7.e4 Nc6 8.Ne2 dxe4 9.fxe4 Be7 10.Bf2 0-0 11.h3 f5?! 12.e5



    The most significant feature of this position is the Critical Point (CRPT:) d4. And now let us see how is constituted an isolated pawn:

    12...Rd8 13.Qc2 Bd8 -/+ 14.Nd2 cxd4 15.Nxd4 Nxd4 16.Bxd4 Bh4+ 17.Kd1 Qc7 18.Qb3 -/+



    The main fact of this position is the existence of the Isolated Pawn e5 which is equally the new Critical Point (CRPT:) of the position.

    (Classical Chess Theory - New Chess Theory - NCT IX - "Critical lines & points").

  • «Central Isolated Pawn» CEIP:

  • An Central Isolated Pawn is an isolated pawn located on the d-file (the most usual case) or on the e-file. Such a pawn deserves attention and sometimes may be relatively strong (Classical Chess Theory).
