Stated plan
Attack the white queen with the rook to gain tempo and central dominance, exploiting the tactical point that Qxd4 loses to cxd4.
Reasoning
The black rook on d6 can jump to d4, directly attacking the white queen on c4 along the 4th rank while remaining safely defended and centralized (no white piece can capture it there). This forces the queen to move, since if it captures the rook, cxd4 wins the queen for rook and pawn, and any other queen move loses time/coordination while black's strong e4 knight and active rook dominate the center.
