on the h4–d8 diagonal and forms a pin of his own on the c3 knight (exploiting the absence of the White's queen bishop from the queenside). If Black later plays dxc4, there may be threats against the g5-bishop. Note that 5. cxd5 cannot win a pawn because of the Elephant Trap
. The main line continues 7. Nd2 Bb4 with the threat of ...Ne4 and pressure along the a5–e1 diagonal.
