TRANSPOSITION
CENTRE PAWN OPENING to PONZIANI OPENING
Black developed his queen's knight to support his king's pawn and deter White from playing an aggressive 3.P-Q4 for control of the centre.
White transposes to the Ponziani Opening start by deploying his King's Knight to KB3(f3), supporting his P-Q4 plan and threatening Black's KP.
