A 5min. Bishop Sacrifice

A nice Bishop Sacrifice on f7 leads to a huge lead in Whites play, but ultimatelly I run into time trouble.

By the time the repetative checks start I'm in time trouble.  I find that my apponents start to play so as to run out my clock.  This doesn't bother me since at my level I'm more interested in making correct, good, fast calculations, which I believe I have done during this game.
