Sicilian Kalashnikov Middlegame (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e5 5.Nb5 d6) Chess Puzzles

The Sicilian Kalashnikov middlegame arises after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e5, where Black chooses ...e5 immediately instead of the Sveshnikov's ...Nf6. Black gains central space and development time, but the d6-square can become a target while White often uses Nb5 to increase pressure.
