Sacrifice the Lady

Queen sacrifices are understood pretty well even by people who do not particularly enjoy chess. Non-chess addicts realize that giving up the most powerful piece on the chess board represents a burn your bridges sort of conviction where a miscalculation could result in a disappointing loss.

 Also there is something rather romantic about parting with a piece of such potency from an artistic perspective. In the following game played at the internet chess club, White(inito from Russia) has built up quite an attack against Black's King but also has an exposed King and needs to finish quickly. Can you find the move that will force Black to tip over his King or force checkmate?



 Remember the hint Queen Sac as that is an enormous amount of information which should lead you quickly to the solution.
