Q+A for beginners(and everyone else)
Im a aggressively tactical player. What opening should i play?
A couple options
1. The Sicilian(literally any variation, white or black). The sicilian is full of tactical options and quite often has opposite side castling which leads to many tactics. The most tactical variations are the Dragon, Grand Prix, and Najdorf.
2. The French Poisoned Pawn Variation(either side). The French Poisoned Pawn Variation, reached by 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5 5. a3 Bxc3+ 6. bxc3 Ne7 7. Qg4, is a very tactical position. Both sides often sacrifice many pawns in this line for the initiative, and there are so many tactics in this variation.
3. King's Indian Mar De Plata Variation(either side). This variation of the King's Indian Defense is Chaotic. White plays on the Queenside, Black on the kingside. The tactics usually are on the black side, with pawn sacrifices on g3 and bishop sacrifices on h3, but white also has his queenside tactics.
Here is the sicilian:

What should you do if everyone around you is pressuring you to play, even if you do not want to, and have great expectations from you ?? What should you do first, play, do tactical training, or simply improve opening,endgame and middlegame knowledge ??
"... In order to maximize the benefits of [theory and practice], these two should be approached in a balanced manner. ... Play as many slow games (60 5 or preferably slower) as possible, ... The other side of improvement is theory. ... This can be reading books, taking lessons, watching videos, doing problems on software, etc. ..." - NM Dan Heisman (2002)

"... When you get to apply - in a real game - what you've learned from a book or computer screen, the information is reinforced in a powerful way." - GM Andrew Soltis (2009)
On Jan 28, 2015, a player (who got over 2300) told us about his start:
"... when I was a kid (10 or 11) playing in USCF events for the first time, I just wanted to PLAY. I didn't care if I got smoked or not …"
I can understand if chess is just not something that you want to play, but, in that case, there is no reason to bother with tactical training, etc. If you are intending to play eventually, and just holding back until you feel better prepared, you are making it harder for that preparation to be effective. Here is a quote about reluctance to use an opening:
"... I think people tend to be afraid of the main lines. They think: ... sure, I'm going to take up (say) 5 Bg5 against the Semi-Slav, once I've got time and learned it properly. ... My advice is - don't bother. The more you learn anyway, the more you'll recognize how little you know. ... 5 Bg5 is a good move - get it on the board, get ready to fight, and see what happens.
Sure, there will come a time, whether on move two or move twenty, when your knowledge of theory runs out and you have to decide what to do on your own. ... sometimes you will leave theory first, sometimes your opponent. Nothing will stop this happening. It happens in every well-contested GM game at some point, usually a very significant point. This is a part of the game: an important part, something you have to get better at. ... to improve you have to challenge yourself; ..." - IM John Cox (2006)
And here is another one about using an opening in a real game:
"... The way I suggest you study this book is to play through the main games once, relatively quickly, and then start playing the variation in actual games. Playing an opening in real games is of vital importance - without this kind of live practice it is impossible to get a 'feel' for the kind of game it leads to. There is time enough later for involvement with the details, after playing your games it is good to look up the line. ..." - GM Nigel Davies (2005)
If the concern is fear of causing parents to be disappointed, I have to admit that I am not sure how to handle that. For what it is worth, I think that parents need to understand that nearly everyone has trouble when just starting to play chess.

How do I avoid things like discovered attacks or forks
I try to but I always miss something
By playing slower games!
And do a lot of them in the tactical section of this site to make sure you can master them.
Forks are not had to see after a few exercises.
"... Sure, fast games are fine for practicing openings (not the most important part of the game for most players) and possibly developing decent board vision and tactical 'shots', but the kind of thinking it takes to plan, evaluate, play long endgames, and find deep combinations is just not possible in quick chess. … for serious improvement ... consistently play many slow games to practice good thinking habits. ..." - NM Dan Heisman (2002)

"... The best solution, as in many things, is a healthy balance. I would guess up to ninety percent of your playing time should be slow games (thirty minutes for each player or preferably more) and the other ten percent speed games. ..." - NM Dan Heisman (2009)

"... I recommend that if you are a beginner, you should avoid speed chess for a variety of reasons. Among them:
- it can get you into a variety of bad habits,
- cause inexperienced players to rush in slow games, and
- can be very frustrating when you are not very good and can't see the chessboard very accurately in a short glance.
However, once you get good enough to have sufficient board vision and tactical vision to play speed games, I do recommend you add them to your practice repertoire. ..." - NM Dan Heisman (2017)

what is the most efficient way to improve? I have books, tactic training, watch youtube videos, and play of course. I sometimes feel like jumping between many resources is overwhelming
