Online or Live? Or a general game of chess? To answer the latter: Learn the opening principles. Start with a centre pawn. If your opponent doesn't prevent it in any way, move the other centre pawn too. Develop your minor pieces, preferably knights before bishops. Castle early, preferably on the kingside. Don't hang pieces. Learn some basic tactics. You should be fine.
Good Luck!
King on e1, Queen on d1, Rooks on the a and h corners. That's usually a good start. Unless you're playing FischerRandom (chess 960), then all bets are off.
1NaturalDisaster:
Don't perceive me as rude, but the second one looks rubbish. The first one is somewhat bad. The last one is okay.
OP:
I recommend the Italian Game, Queen's Gambit, French/Caro-Kann, Semi-Slav and Grunfeld.
In all seriousness, it's a better idea to learn opening principals before trying to learn specific openings. I mean you can try to learn some book openings if it pleases you, but don't focus too much on them yet. At the level you appear to be at, in an actual game, that stuff's going to go right out the window by the second or third move because you'll mostly be playing against players with no clue about openings.
There's a Learn Tab above there. Hover over it, and there are Study Plans. They can help beginners a lot.
Due to your rating I am guessing you are a beginner because of this I recommend e4 as white and if your opponent plays e4 respond with e5.
I like the kings gambit. You can be pretty aggressive.
watch: http://www.chess.com/video/player/how-to-crush-your-opponent-in-the-kings-gambit----part-1 for aggressive moves
the last one is a good way to counter that position. But, in openings, the best first move for me is d4
agree d4 and c4 are best by test
any ideas welcome
