Nice!!!
You chased the Queen into the back, and forced the King out.
The Scotch Game (not to be confused with the Scotch Gambit, which usually arises after 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4. Bc4) used to be my opening of choice as white before looking at the Spanish and preparing some lines of the Italian for surprise value. 5.Be3 is the most common at that point in the game, but Nxc6 is not terribly uncommon or bad really - it's still book, the second choice. Black's usual reply is 5...Qf6 and white follows up with something like Qd2, though there are several options that are ok.
This really was a fun game, and a casual one. I'm not just saying that because I won, but because this a game showcase forum, I'll post this one game where I actually won (trust me, I've had my share of losses :)). Anyway, I think a couple of wasted moves on my opponents behalf gave me the win. I don't have time to annotate the game thoroughly, but I will say this much, my opening was not that great, but my end game was in my opinion pretty sweet. Leave contructive comments.
