SLAV TRANSPOSITION
(Transpositional route) to EXCHANGE VARIATION
White's QBPawn on QB4(c4) removes Black's QP on Q5(d5) and invites capture. Solid but inferior, as Black can defend himself quite well. W-Alt.
Black's QB3(c6) Pawn removes the doubled QP, forming a fixed centre of mutually blocked pawns.
