TRANSPOSITION
RETI'S OPENING to QUEEN'S PAWN SIDE DEF.
Black's wary KKt prevented 2.P-K4 and supported 2..P-Q4, although a KB fianchetto is also likely.
White advances his Queen's Pawn for early K5(e5) control (usual is 2.P-KKt3) and transposes into a QP Side Defence variation, perhaps intending a Colle System. Black often transposes further by 2..P-QKt3 into the Queen's Indian Defence. W-Alt.
