Attacking Chess!! Wedge the Kingside

Sometimes it's a powerful idea to open up the kingside and watch the bare King run around try not to get checkmated, and sometimes a better idea is to wedge it shut!  

Hi there.  This is Stacia and I hope your attacking spirit is ready for some more action because we are going to continue looking at attacking ideas this month!   Today's idea is Wedging the Kingside and if you don't know what I mean, and you don't, I mean that a kingside fianchetto structure without the fianchetto'd bishop is vulnerable to this style attack.

And now let's witness this idea in action in a real game.  This position analyzed in the quick video. below    See if you can find the attacking idea, but what's more, the defenses black has in response.  If you can crack those defenses mate is unstoppable!
