TRANSPOSITION
HEINRICHSEN OPG. to NIMZOWITSCH DEF.
Black developed his queen's knight to limit any White P-Q4 advance contesting Black's K4(e5).
White transposes into a Nimzowitsch Defence variation (a line itself used mainly for transitional purposes) by advancing his King's Pawn to the still vacant centre, taking control of Black's Q4(d5).
