My "Immortal Game"

I played a positional queen sacrifice, similar geometrically (but not too much positionally) to Lilienthal-Capablanca. Black decided to oblige, even though he very obviously was not forced to, gave White too much compensation and lost the resulting endgame (which could maybe serve as a basis for some kind of endgame study with some pretty-looking mates - of course, I missed all of them!).
