TRANSPOSITION
PILLSBURY DEFENCE to PHILIDOR'S DEFENCE

Black's KP move (with QP support) freed his Q+KB and challenged Black's QP - inferior but playable.
White develops his King's Knight to KB3(f3), attacking Black's KP further with a plan to exchange pawns and then queens (preventing Black castling) so as to ultimately win a pawn by 6.KtxKP. W-Alt.
