In order to double the rooks on the e-file, where Black has a problem with the unstable bishop on e6, as well as with the e6-square itself.

2...Bg8? 3.Nb5! Qd7 4.Bxf5 White wins a pawn.

Black's previous move left this diagonal unattended.

An excellent strike based on the line: 8...hxg5? 9.hxg5 cxd4 10.Qd3! with a winning attack. After 8 Ng5! White enjoys a clear initiative and later won the game.

Clearing the e-file for the rook, in order to enhance an attack on Black's weakened kingside.

Black is urged to speed up his development.

If 1...fxe4 2,Nxe4 d5, then 3.Ng5! , followed by Bh3 with a strong attack.

Simple and strong. Now the rook controls a lot of important squares.

4...g5 5.Qh5! Nxd6 6.Bh3 Black is still in trouble.

Black resigned.
