Skewer :sk
01 The :sk - another ‘type of combination’ is called a skewer.
Below:
A-BS threatens to capture B-QU. When
B-QU moves away B-RO is subsequently captured by A-BS.
02 Similar to a pin,
but not the same. A :sk
is an attack along a file, rank or diagonal which threatens a high value MP/mp. After this MP/mp has moved, another lower value
MP/mp is exposed.
Creating a skewer. If the BS moves from E01 to C03 the KI
is placed in +CH. The QU is captured
on the next move.
03 An example of this is a
protected BS (:pr-BS) attacking a RO through QU1. After QU1 moves the RO is captured by
the BS. Even if the BS is subsequently
captured there is a gain of 2 points as a RO is worth 5 points compared to a
value of 3 for the BS.
04 Another example is a RO
checking the KI with QU1 being placed behind on the same file. When the KI moves QU1 is captured by the
RO. A MP/mp is attacked by a less valuable unit. The attacking MP can capture a MP/mp
beyond.
05 An attack on two MPs/mps,
along the same rank, file or diagonal. An attack which forces a MP to move and so reveals an attack on a
MP/mp of less or higher value.
