I still think that you need to be a fairly high-class player to be able to break all of those rules like "get castled quickly, " etc.  There are plenty of opportunities for dynamic counterplay in those modern lines, start with those that sees Black rapidly developing his entire kingside and I suspect that your results will improve.

You are aware of the fact that Karpov made Kasparov switch to 5...a6 because of the Keres Attack?

I've been looking at games very slowly. There seem to be an awful lot of tactical bombs here that Black needs to be aware of but the positions are interesting. 



Apparently this Qh3 maneuver is a lot more dangerous than it looks and the pawns are as vulnerable as anything else in these positions. I'm not really used to looking at the board this way unless I'm doing tactics puzzles... 

I can see why people suggested the modern Scheveningen now and how staying in the center seems to require you to have a really good eye for tactics. But the games of Kasparov are what really drew me to this opening and so I'm going to keep trying to play this way. I don't think my opponents will play this aggressively right now but it's still really interesting to learn these tactics.

I too think the modern lines are easier to start with than the classical lines.  But that doesn't have much to do with leaving your king in the center.  Neglecting your king is a no-no, whichever form of Scheveningen you play.

In the classical Scheveningen, one of the more famous examples is Lasker-Pirc, Moscow 1935.  Pirc left his king in the center to get his queenside play going.  And got crushed for it:






          

One small tip, study anti sicilians carefully as well since at club level the open sicilian is very rare. Open sicilians becomes more common when opponents has heiger rating.

Stick with it.  It sounds like you're learning.  But you may want to brush up on the basics first.  You're not going to do well in any opening if you neglect your king safety.  In these Classic Schevy positions, you want to play ..Be7 and ..0-0 as soon as you can, and stop leaving your king in the center.

It would be good to study tactics too.  Yes, you can switch to an opening that is quieter than the Sicilian, but if you do that, you'll just be avoiding the problem, rather than solving it.  And eventually your unfamiliarity with these types of tactics will hold your chess back. 
 

   

Well, yes. And that's still true even after you study the opening. You will be attacked early and often if you play this opening. If you don't like being attacked, don't play it. 

The tone of your comments really speaks of a painful misconception common among inexperienced players about what studying an opening and understanding themes in pawn structures can and can't do for you. A good strategic understanding of an opening is just a kind of coloring of your general understanding of chess--it can't take you so very far beyond that. Yes, you can beat weak players with a recipe opening like the Stonewall or Colle, and yes in internet blitz you can lose to some completely unsound BS where you would have won if you knew the refutation, but in slow chess and mainstream openings these are much less the case. Being subjected to an unsound attack should not be your biggest worry--unlike in blitz, you will have time to discover its disadvantages. Being subjected to a sound attack and not knowing anything about it is the real concern of this kind in studying an opening--and there are plenty of those to worry about in the Scheveningen. But beyond a certain number of moves, normally neither you nor your opponent will know if an attack is sound or not!

On the other hand, if you're not strong enough to think of reasonable replies (not refutations) to unexpected opening moves, that's ok, for if your opponent is of a strength similar to yours, then an opening advantage won't mean much anyway. The game will probably be decided by heavy mistakes on both sides later on. So there again unsound attacks in the opening should not be an excessive concern.

All you can do profitably at this stage is memorize the basic theory (like the summary LeeRoth so generously provided below) to cope with sound responses, maybe look up traps, inspect a bunch of grandmaster games in these lines (especially from the main tabiyas) in a database to see how Black wins when he wins and loses when he loses, and gain experience over the board. 

It's not worth doing a lot of more detailed opening study before you venture the opening in practical play, because you really can't tell if you like the positions or not--or how far in your opponents will know the theory (it's useless to memorize some 20-move forcing line if no one you play even gets close to entering it). And you can't a real feel for the positions from  a book, but only by losing a lot (and winning).

So I say jump in and enjoy. It'll be fun to be able to say you play the Scheveningen! (I only play lines that I enjoy and enjoy identifying myself with). Good luck!
