THE CHIGORIN DEFENCE

Board Position
One of the several Irregular Defences to the Queen's Gambit. Black declines White's 2.P-QB4 gambit by 2..Kt-QB3 counter-attacking White's QP (move 2wb, left), intending to develop pieces as rapidly as possible so as to attack White in the centre - often after a Kt-KB3..B-KKt5 half-pin leading to a B-for-Kt exchange (typically as move 7wb, right). The defence also arises by the same first two Black moves in a Queen's Pawn Game. Board Position
This defence used to be played exclusively by the great 19th Century Russian master, Mikhail Chigorin (or Tchigorin, his proper spelling), even in world championship matches. However it is regarded as an unusual way to defend the Queen's Gambit and analysts tend to doubt its soundness in top level play.
