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.
... d5 ;D00 Queen's Pawn Game 1.d4 d5. Black
;answers symmetrically, challenging the
;center directly.
2. c4 ... ;D06 Queen's Gambit. The Queen's Gambit
;is the logical response to Black's
;symmetrical defense, challenging d5.
... Nf6 ;D06 Queen's Gambit / Marshall Variation.
;Awful is such a strong term.
;Positionally, this is an awful defense.
;Black gives up the center for absolutely
;nothing! 3.Nc3, 3.cxd5, and3.Nf3 are the
;favorite moves here, all of which
;extract extreme punishment from Black's
;positional transgression, though 3.Nc3
;allows Black to transpose to normal
;positions with 3...e6.
3. Nc3 ... ;Opening Book move
... e6 ;D35 Queen's Gambit / Declined / Normal
;Defense (transposed).
4. Qc2 ... ;Out of Opening Book. Bg5 would have been
