“Between [a] skewer and
double attack, you have
some of the most basic
but very deadly means of
creating damage to your
opponent and reaching the
desired result.”

Chess has a rich vocabulary in many languages, and
English chess lingo contains many terms from French,
Russian, and German. Considering the popularity of chess in
the Russian-speaking world, it’s no surprise that Russian has
many specific chess terms that don’t translate so easily into
English. Garry says the Russian “ли�½ей�½ый удар”
(“lineynyy udar”) for x-ray, or skewer, could be literally
translated as “linear impact!”
•
A “poisoned” pawn or piece is one that looks like it can be
won freely, but in fact cannot be captured without suffering
consequences. There is even a famous line in Garry’s beloved
Najdorf Sicilian Defense called the “Poisoned Pawn Variation,”
popularized by American World Champion Bobby Fischer.

Skewers, also called “x-ray attacks” are performed on a line
with a queen, rook, or bishop. The more valuable piece on the line
is attacked and when it moves aside, the piece behind it is lost.
Garry suggests to think of it as the opposite of a pin, which is
when the less valuable target is in front.
White to move and find two winning tactics. One is a pin, not a
skewer.
Both 1. Bc3 (skewering the queen and rook) and 1. Bg3 (a close
cousin of skewer, a “pin”) work. 1. Bg3 is better since you will win
the queen instead of a lesser piece.
“You have to look for the maximum outcome,” Garry reminds.
