TRANSPOSITION
KING'S FIANCHETTO OPG. (Sicilian V.) to BARCZA S.
Black answered White's centre invitation by a QBP to control Q5(d4), awaiting further White intentions.
White develops his King's Knight to KB3(f6) to challenge Q4(d4) control, transposing into the Barcza (a system where he withholds either P-QB4 or P-Q4 until Black chooses a formation allowing White to transpose into his own preferred variant).
