General Observations
Weaknesses in the pawn structure, such as isolated, doubled or backward pawns and holes, once created, are usually permanent. Care must therefore be taken to avoid them (but there are exceptions — for instance see Boleslavsky hole below). In the absence of these structural weaknesses, it is not possible to classify a pawn formation as good or bad — much depends on the positions of the pieces. However, the pawn formation does determine the overall strategies of the players to a large extent, even if arising from unrelated openings. Pawn formations symmetrical about a vertical line (such as the e5 Chain and the d5 Chain) can be deceptively similar, but they tend to have entirely different characteristics because of the propensity of the kings to castle on the kingside.
Pawn structures often transpose into one another, such as the Isolani into the Hanging Pawns and vice versa. Such transpositions must be considered carefully and often mark shifts in game strategy.

Famous quotes containing the words general and/or observations:
“The General Order is always to manoeuver in a body and on the attack; to maintain strict but not pettifogging discipline; to keep the troops constantly at the ready; to employ the utmost vigilance on sentry go; to use the bayonet on every possible occasion; and to follow up the enemy remorselessly until he is utterly destroyed.”
—Lazare Carnot (1753–1823)
“By sharing the information and observations with the caregiver, you have a chance to see your child through another pair of eyes. Because she has some distance and objectivity, a caregiver often sees things that a parent’s total involvement with her child doesn’t allow.”
—Amy Laura Dombro (20th century)
