White to play and win

As regular readers will know, I am an admirer of Troitsky’s studies. Here is another.

After White’s first move, there are three different lines to explore, two of which leads to clever, quick and different mates. The third line is longer and shows Troitsky’s genius to its full as he pulls a win out of a seemingly drawn position.

This is one of the harder puzzles I have put on this site but even if you do not fancy a crack at it, looking at the solution is a must! Enjoy!
