sweet rook sacrifice

Hello!

This is an online game that I recently finished. Early out of the opening, I achieved a material advantage. However, I was having difficulty finding a way to break open the position and simplify the game or get at his king. On move 32, though, I found a really nice way (involving a rook sacrifice, as promised) to get at his king and either win immediately if my opponent did not find the best defense, or simplify into a winning endgame.

My opponent did not find the best defense (I didn't find the very best offense, either) and the way in which he loses is quite spectacular.

Enjoy!

A good game and a good "interference" sacrifice, well spotted. I wouldn't worry too much about what your engine says, machines play unthematic moves that human brains are mostly incapable of finding.
