Board Position
A resiliant if somewhat passive semi-open defence against White's QP+KP centre. Named after Yugoslav IGM Vasja Pirc (pronounced "peerts") who improved the (usually preceding) Pillsbury Defence intro.
Black replies 1..P-Q3(d6) before 2..Kt-KB3(Nf6) against White's classical centre (move 2wb, left) to discourage an immediate 3.P-K5 advance against his KKt, before Black's king's bishop fianchetto then becomes central to his plans for counter-attack.
Board Position
Having some similarities to the Modern Defence (qv.), White must decide whether to proceed modestly or annex the centre by for example the Austrian Attack (move 5w, right) or the Byrne Variation.
