which opening?

I really can't think of any decent openings that I should play.

of black or white...

As of right now, I play the two knight defence as white or I play the queen's gambit if I want to change my game upa bit.

For black, I play the sicilian against the e4 and i usually play the queens gambit declined/slav against d4.

Could you guys suggest some other openings and post some nice games so I can see how effective they are?

As of this moment, your rating on chess.com is 1234.

That's a really cool number what with the sequential thing. Have you considered not playing any more? It would be a shame to mess up such a great rating.

I'd endorse the Bongcloud but recent mention of the Fool's Mate Declined has me intrigued.

If you decide to continue playing, best of luck.

I like the idea of playing the main line openings because by the time you're higher rated you'll have a good grasp of the basics.  The QGD as black and the ruy/guioco as white or black are great choices.  The sicilian is very tricky of course.  If you don't like playing ..e5 vs e4, you should check out the french.  It's a great counter-punching defense with an easy to learn setup, and a lot of white players have trouble with it.

try playing the scotch gambit as white, against players rated below 1700 I scored some very nice (and a lot of) wins. it opens the game and white has a very aggresive attack if black is not careful.

of course if played correctly by black, you might just get a small advantage

against d4 as black, I usually play the dutch, but this is trickier. The dutch kills the d4-e4 initiative(especially the stonewall) but you have to be careful in the opening
