}
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.}
1...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.}
2...dxc4
{D20 Queen's Gambit / Accepted. The Queen's Gambit Accepted opens a number of important variations in Queenside
openings. Rarely does Black try to hold the pawn. Instead, he attempts to make positional gains while White regains it.
Fianchettoing the Queen's Bishop is common.}
3.Nf3
{D21 Queen's Gambit / Accepted / Accepted 2.c4 dxc4 3.Nf3.}
3...Nc6
{Out of Opening Book. a6 would have been in the Queen's Gambit / Accepted / Alekhine Defense book opening.
