My System Part II

Notes on the second part of Nimsowitsch's My System

Relation of positional and tactical play Positional play generalizes the tactical ideas from Part I
Amateur's offense against positional play They always want to be doing something.
Master's offense against positional play They overestimate the accumulation of small advantages.
Response to flank attacks Attack in the center
Before attacking… Consider consolidating moves
The most important aspect of positional play Prophylaxis: anticipation of problems both external (enemy moves) and internal (our position).
External prophylaxis Make freeing pawn moves more difficult to achieve, if not prevent them.
Internal prophylaxis Over protect key strategic points
Benefit of over protection The protecting position can be strategically useful in and of itself (increased radius of activity)
Over protecting weak squares Don't do it unless the weak square supports a strong one (like a base pawn).
Second aspect of positional play Mobility of the pawn mass in general (not necessarily every pawn)
Prophylaxis vs. pawn mobility Prophylaxis is a means to pawn mobility, although useful it itself
The Balkans of the chess board The center. The focus of the battle will never be far from there.
What to do with closed centers 90% can be opened with a single move, which is preferable to attacking on the flanks.
When central pawns are removed You must occupy the center with pieces
True strategy Deliberate over protection of the center and centralization over flank attacks.
Replacements for central pawns Centrally posted pieces or lines of attack that restrain enemy central pawns.
Definition of the center The squares in the middle of the board (not the pawns/pieces on them)
Relationship of center and flanks Occupying the center gives you control on both flanks, and allows switching flanks
Best piece for dominating the center Pawns, because they are the most stable
The drawback of central pawns They are an obstruction
True control of the center Restraint of the enemy's center
Disadvantage of doubled pawns They allow for the ultimate in restraint because they can't advance as effectively.
Compact doubled pawns Doubled pawns in contact with other doubled pawns
What to do with enemy doubled pawns Push them into advancing that pawn mass.
How doubled pawns are like a limp It's only a problem when you're moving
Static weakness of doubled pawns One that shows when you attack them
Active weakness of doubled pawns One that shows when they move
When to undouble pawns When they have a static weakness. The remaining pawn will be weak
When to attack doubled pawns with pawns When they are compact/advancing or isolated. Otherwise goad them into advancing.
The strength of doubled pawns They make it easy to hold out when they stand firm
Mysterious rook moves Moves to occupy files that are not open but will be if the opponent tries a freeing move.
False freeing moves Freeing moves in an undeveloped postion that can't capitalize on the freedom. Don't worry about them.
The nucleus of restraining a pawn majority An open file and two ways to blockade
Qualitative pawn majority A wing advancing on an enemy base pawn. It is qualitatively superior.
The saw position Pe4, pd6, pf6
Restraining mobile central pawn (1) The passsive saw position
Restraining mobile central pawn (2) Restraint with aggressive pressure (from a rook)
Restraining mobile central pawn (3) Cause it to become backward or isolated
Restraining mobile central pawn (4) Blockade it.
Restraining mobile central pawn (5) Take it.
Three general steps of restraint Restrain, blockade, destroy
Two possible side effects of doubled pawns A trapped bishop, and a cramped position getting in the way of defense.
Dichtomy of the isolated queen's pawn Statically weak, dynamically strong
Strengths of isolated queen's pawn The knight outpost on e5 is superior to black's on d5 because of it's king side threats (esp. with the light bishop)
Weaknesses of isolated queen's pawn d5 becomes better outpost, the pawn needs defenders, and d5, c4, and e4 can become weak squares in endgame. White needs penetration on c7.
General lesson of isolated queen's pawn It's not just an isolated pawn that is weak, but the squares around it.
When to attack with isolated QP When the opponent takes pieces from the king side. Until then develop and secure d4 (Be3!). When you attack, sacrifice
Good isolated QP position for white 1 d5, e6xd5, recapture with a piece (centralized)
Good isolated QP position for white 2 white has play on the c file
Good isolated QP position for black 1 Getting to the endgame with QP still isolated
Good isolated QP position for black 2 Nd5xNc3, bxc3, lay siege to c3
Where failed attacks on isolated QP go To the queen side.
The isolated pawn pair c3 and d4 pawns as an island, often a consequence of isolated QP. If black can blockade it's good, as white is cramped.
The hanging pawn pair c4 and d4 pawns as an island. Good for white, threatening c5 and d5
What hanging pawns inherit Statically weak, dynamically strong
The hanging pawn pair trade off To make them strong by advancing one of them, you must give up play in the center.
When advancing hanging pawns is worth it When the potential blockaders are open to attack, or when the blockade will cost too much to maintain
Strength of bishops Range
Weakness of bishops Squares of the opposite color
Horrwitz bishops Bishops operating on adjacent diagonals
How to use Horrwitz bishops One forces a pawn to move and block, the other attacks through the square behind the pawn, or uses the weak squares created.
Pawns and bishops A bishop pair can more effectively support a pawn mass than a knight pair.
Pawns and knights Use the blockaded pawns to cramp the knights as well.
Bishops in closed positions They are weak against a central, hard to attack knight.
Hypermodern strategy Hold off on pawns in the center until necessary, then use them supported by fianchettoed bishops.
Protection against hypermodern strategy Over protection of the central squares
Over protection and flanks Over protection of the center makes the flanks resistant to attacks.
What to over protect Strategically valuable spots that will lend power to the protectors
What not to over protect Weak pawns or areas (unless they are strategically valuable).
The two types of weak pawns Inherently weak pawns, and pawns that will become weak after another pawn (yours or foes) moves.
Maneuvering Attacking a weakness with alternating pieces, keeping them mobile and the defenders static.
The pivot of a maneuver The square which all the pieces move through or connect with.
Attacking on two wings An attack on one wing can cause a disruption and subsequent weakness on the other.
Maneuvering on the defense A large number of targets can compensate for a low number of threats.
