Answers.Body: <p>The SOS ("Secrets of Opening Surprises") books and articles (in New in Chess magazine) can be good references.  Once in the USATW I was paired up against a 2450 rated player.  I found references with a quick online search that he played the Caro-Khan.  I walked in the bookstore and looked in an SOS book and found a line Kasparov used in blitz a lot.  After 10 minutes of preparation I was armed  to get my well booked opponent out of his element and I won my best game of the tournament.
  I've done such things with the Chess Informants a lot including preparation against Yermolinsky in the US Open.  I would say Chess Informant is best if you have the time and money.</p>

Answers.Body: <p>i don't know you want a opening repertoire for positional or attacking one. I use to play mainly positional repertoire but for some blitz chooses attacking one. I followed some lectures of yassar serwain's from saint luis club , it is available in youtube . I also follow a pdf of gufeld's repertoire <a href="https://e-nautia.com/erich.g/disk/LIBROS%20DE%20AJEDREZ%20EN%20PDF/An_Opening_Repertoire_for_the_Positional_Player.pdf" rel="nofollow noreferrer">Repertoire of Gufeld and another man</a></p>
  
  <p>And also following some advice from GM Arthur Yusupov . But at last I must say that if you do not rely on your repertoire then you cannot become a good player , and if you do not make a hard work on your openings then you cannot make a solid typical opening (most of the player don't like this type of opening which has been analysed , like with 48 moves or more!! ) like Lev poluguasky (Pronouncing wrong?!) , His openings homework was great , every player was scared to play with him , he is mainly known for his hardwork on openings (his favorite opening was sicilian najdorf , and he invented the opening Sicilian Najdorf Poluguasky variation , which is sharp like axe ) , if you make a hardwork on your opening you can be one like him . And at one stage he said by this hard work attitude  he can prepare any master player into world champion.</p>

Answers.Text: This does not answer the question, and some of your comments are pretty "dubious". Yes, having a solid opening repertoire is important, but you need to vary as well, and being the first to come up with a "novelty" in a game can be a great weapon in winning the game at high levels. Always playing the same lines means you are a sitting duck where any opponent can prepare whatever variation they want against you.

Answers.Text: It depends a lot on the level you're playing at. Once you reach a higher level (say 2200+), and many of your games are in online databases, people can prepare for you and so either you need to know *every* variation that can be thrown at you, or you need to vary your openings sufficiently that your opponent cannot easily choose a line to play against you for say the first 20 moves. The element of surprise is very important in openings, even more so than playing the objectively best moves.

You miss your preparation almost always anyway and you mainly need playing abilities. Even if you succeed in home preparation, what is it worth? 20 minutes and 20 centipawns? This is just small part of the game.

Comments.Text: @hoacin What I find the most useful is using ChessBase 14 with a large games database, using the "prepare against opponent" feature of CB14 to easily get an idea of your opponent's repertoire, and then use an opening book together with an engine to find surprising, not so often tried sidelines. It involves some manual labour, but it's been worth it for me so far, almost always being "in book" longer than my opponents.
