Master White and Black at the Same Time or Focus on One First?

Honestly though, for SERIOUS games and CC, play a reasonable and SOUND opening. Do not study random crap like the Englund.

I mean, why would you even want to give away a pawn for infinitismly small compensation on move 1? You can get a better and much more sound game playing good, respectable stuff like KID, QGD, Open Sicilians....list goes on and on

And yes, stick with the reasonable+sound opening for a while...

Agree. Chess study takes a very long time. Why waste time with crap openings???

There are openings that will solidly teach you important things such as tempo, tactics, strategy, pawn structure, endgame, etc. And you need to know some of them to find out which one suit you well.

Imo, some useful openings are KID, Sicilian Dragon, Caro-Kann, King's Gambit, may be French (never been in my opening repertoire).

Sicilian is played by the most, but funny thing is, except for Dragon, I feel like it is a waste of time for class-B players.

The defense depends on the offensive, and vice versa. If my opponent attacks make him retreat. If he's defensive exhaust his patence until he m,akes a mistake. The are two sides two every game, but neither side can ever become fixated. One must be prepared to deal with the element of surprise!

The Dragon?! Ive seen people play that quite a bit around here lol, mostly kids though.

I think the Scheveningan is a better choice though as its supposed to be the cornerstone of the Sicilian pawn structures and your position is more solid than the regular Dragon.

Of course expert like you don't want to play the Dragon. But in lower level it is not weak, and teach a lot of usefull knowledge (tempo, imbalance, etc). Of course, an opening should be studied properly (not just used sporadically).

The Scheveningen is one of the most high level opening. In high level, you often need complexity that will give chance for Black to win, even if you have to play a theoretically difficult position. That's one reason why I feel that Sicilian in general is useless for beginners. Scheveningen is even worse. I would love to pick it if I play in tournament time control. But in less than 25/0 time control, I'll probably have to resign before move 25. The Keres Attack, that's my line against the Scheveningen.

I practiced as black a lot and now I sort of regret it because I am not as good when I play white. I think you should practice both as much as you can.

 I do so love playing against the Keres maybe my opponents just don't use it right I'm sure but for a highlevel opening I sure do have some good games playing against it.
