works well...
What is YOUR most common chess opening?

The most common opening has to be the Ruy Lopez.
The most common defense has to be the Sicilian.
Yeah i know here comes the arguements against it!

NOT saying it's great: but most common for me is 1 e4 e5, 2. Nf3 Nc6
what is not great?

but you are not defining the game . Now will you go Bb5 for a Lopez or Bb4 for a spanish game? These lineages are well researched. I like the picturesque 1.Nf3 which can by transposition go to numerous other branches.
I did not think of that...
Thanks MidnightExpress1 !!

Queen's Gambit and its derivatives (slav &c.), for both colours. GMs choose these, why should I lag behind? :)

e4/Nc3/Nf3/d4 that's mine most of the time.
that is what I do; pretty powerfull opening :-)
Because it let's you bishops move far....

I used King's Gambit before I used this one...
Which worked well...but...
Some of you might think you are just loosing a pawn
Obviusly you loose one but, most importantly you control
The Center of The Board!!!
Mine is
e4/Nc3/Nf3/d4
