TRANSPOSITION
ENGLISH OPG (Anglo-Fr. Def.) to ORTHODOX QGD.
Black advanced his QPawn to the centre to challenge White's QBP, inviting the Orthodox QGA by threatening 3..P-Q5(d4) with gain of tempo.
White transposes into the "Orthodox" Declined position of the Queen's Gambit by advancing his own Queen's Pawn to Q4(d4), and frees his QB.
