As we all know, a chess game is what you make of it. This is what separates players like me, (beginners) from GM's. But, many people overlook what I think is one of the most important tactics in chess; to know what to do with a blank chess board. How are you supposed to achieve an amazing game, or even put up a good fight against a player stronger than you, if you do not start the game correctly? If you don't, you are just digging yourself a deeper hole before the game has really even started! There are 100's and 100's and 100's of openings, and many are on chess.com. You do not need to know anywhere close to all of the openings ever played, but you do need to know at least 2. Hopefully more, but definatley at least one solid opening when playing white, and one solid opening when playing black. They don't need to be long, and go on forever, just for it to make sense to YOU, and for you to be able to play it confidently.
Here's an easy opening, nice and simple but played often. The "Italian Game: Two Knights Defense, Modern Bishop's opening."
And then the very famous "Queen's Gambit."

These are some very common openings, so go out, and expand your Opening Theory!!
