A senseless sacrifice; but after:
5.Bxe7 Nxe7 Black is also clearly better thanks to his superior minor piece.

A sound extra pawn up, Black went on to win without major problems.

Preventing Black's only active idea, ...Na5-c4. Besides which, a doubling of rooks with Rbc2 is enabled.

1...Ra7 2.Rbc2 Raa6 3.Kh2 is similar.

Preparing a kingside advance with g2-g4, f2-f4 and f4-f5.

This simply drops a pawn. Preferable was 2...c6 with just a slight disadvantage – Yusupov.

With a sound extra pawn, White went on to win.

White has managed to isolate the enemy rook on b7.

With every exchange the inferiority of that rook will make itself more strongly felt.

Softening up the light squares.
