1. d4 ... ;A40 Queen's Pawn Opening. The Queen's
;Pawn opening move is somewhat slower
;than the popular e4, because White will
;not be able to castle for three more
;moves. Its advantage is that it gives
;White more control over tactical
;surprises and often provides more
;lasting initiative and pressure.
... Nf6 ;A45 Indian Defense. The immediate
;development of the Knight is the most
;supple response to the Queen's Pawn
;opening, allowing transposition into
;virtually every type of defense at
;Black's disposal.
2. Nc3 ... ;A45 Indian Defense. By blocking the
;c-pawn, White forces the game out of
;normal Queen-pawn opening lines.
;Transposition to the French Defense is
;now possible, or White may intend the
;Blackmar-Diemer Gambit.
... d5 ;A45 Indian Defense.
3. Nf3 ... ;D02 Grunfeld Reversed / Symmetrical
;Variation (transposed).
