SNG Win Last Night

This is my first post, so bare with me. I'll have significant thoughts in the future.

I was playing at a Sit-N-Go tournament yesterday at Party Poker. I made it to the money and was head up as the chip leader. Here's how the final hand went down:

Preflop
Me: (6235 chips) K-6
Opponent: (1765 chips) ??

I call the small blind to 400. Opponent raises to 800 - I call

Flop:
6-6-6, I have quads
I call. Opponent goes all-in shows (A-Q). I call and win.

I love winning is a cool way. This is poker after all.
