1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 - Sveshnikov move order. 6.Ndb5 - White targets the weak d6 square. 6...d6 - Black defends and prepares ...a6 to kick the knight.
White's plans: Play Nd5, Bg5, Bxf6. Occupy d5 with a knight. Black's plans: Play ...a6, ...Bg4, ...Be7. Active piece play compensates for d5 hole.
