:ba-mp, :ba-PA

“The Reverend Robert Walker Skating...”, Sir
Henry Raeburn
A PA that
has been left behind by its neighbors and can no longer rely on their
support. Not guarded by another
PA. Cannot be advanced with the
support of PAs on adjacent files. Is not :bl (blocked)
by an opposition PA on the same file.
When a PA has fallen behind friendly colleagues, remaining on a modest rank while those to either side have rushed ahead, then
this PA is known as a :ba-PA (backward).
Strictly speaking, this term is generally reserved for a PA which has
little or no immediate prospect of advancing to catch up the other PAs. Like an isolated PA (:is-PA), the :ba-PA is unable to be defended by
another PA. Please see ‘Notation’ for a complete list of mp terms.
See PA (under ‘Major/Minor pieces’). A PA which has PAs of its own colour on
adjacent files (only in front). Such a
PA has no protection of its own. Considered a liability due to being easily
attacked.
A mp that cannot be protected
nor advanced by the support of another mp, is not :bl (blocked) by an enemy mp
and is prevented from moving forward by an enemy mp on an adjoining file. A PA in this position lacks mobility and becomes a weakness
in your position. However, if the
:ba-PA (backward) can capture a mp or MP in an adjacent
file the :ba-PA would again regain mobility.
A PA that has trailed behind friendly colleagues and is no longer
supported by other friendly PAs. A PA
that cannot be protected (guarded) or, advanced without the help of another PA
and prevented from advancing by an opponent’s PA in an adjacent file. A :ba-PA is considered weak because it is
immobile.
A
PA which
cannot be guarded by a PA, or which cannot advance to such a position. A PA which has “fallen behind” the other PAs and it
thus left without the protection of other PAs. PAs are generally much stronger when they are side by side,
rather than background or fragmented in other ways.
Backward PA:
A PA
which, though not isolated, has no PA of the same
colour on an adjacent file either on the same rank or behind it. If this PA is on a ‘half-open-file’ and
cannot advance it can become a target of attack. Place an A-PA on E04 and B-PAs on D06 and E05. If there is no B-PA6 on the board, or if it
is on, say, C05, then B-PA5 is backward.
