Chess Puzzle - Week 2

Hi,

Here is a chess puzzle, courtesy of The Times, for you to try. An easy one this week; it is from

Plaskett - Velimirovic, Banja Luka 1985

White to play and win

Here is another instance of an English player beating up Velimirovic; Plaskett has sacrificed a piece to drive the Black king up the board; how did he now finish it off?

Solution next week.
