Sudden mate in 1 min game! Opponent wasn't expecting that :)

Here's the game for you if you wish to see it:

But if you want it here, with lesser details, then here is it:

I was just playing some games in a tournament, when suddenly I got this game, and I smashed a sudden checkmate, enough to break his ego . I think he must've been like "wtf?", and cursed. Well, this gave a lot of laughs for me . I couldn't post yesterday as I was busy.

Thanks for viewing!

Excellent game

Not sure what that type of mate is called, but it's one of the cleanest, being that it's essentially stalemate +1 extra attacker targeting the single occupied zone.
"Zone Bounded"? I don't read chess theory, eww. I'll just think about it and share with people.
