White is way down on material, so only mate or winning Black's queen will tilt the balance in his favor. This study is just pure tactics from beginning to end, so it is a good test of your tactical ability to solve it from the diagram, without moving the pieces. White to play and win.(And please read the annotations)

Hint: The right choice of the first move leads to the rapid capture of black's queen, but enemy counter-play soon restores the balance. Despite this, it is White who has the last word.
