This is for those of you who are more competitive at this game....

What is your favorite chess opening(s)?

Here is a list of mine:

1. Kings Indian Defense (KID): 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 e6

2. Sicilian Defense; Classical Variation: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d6

3. Smith Morra Gambit is quite fun (A sideline of the Sicilian Def): 2.d4 cxd4 3.c3

4. St. George Defense. A very bad opening, but you can pull surprises with it against beginners: 1...a6

I have a gambit, of my own invention, that I was reasonably successful with, when playing competitive chess.
