Concept of open 'h' file

I lost many games online last night, but managed to win one in the end :) I remembered a concept that I'd seen on a DVD by Roman Dzindzichashvili. The idea is to sacrifice the Bishop on g5 and open the h file. I ended up with a Queen and Rook mate threat and plenty of time to capitalise on my opponent's uncastled King. Here is the game - a 5 minute Blitz.

As usual - any comments welcome!!
