i am so annoyed if a player starts to play sicilian against me i change to king's indian attack.

do you think this is a viable strategy?

I'm not too sure of how the KIA works against the Sicilian, I'm not an e4 player. But in general, I'd advise against switching up your game because a certain opening annoys or bothers you. I used to do this quite a bit (I'm looking at you, Benko gambit ) and was given some good advice about not doing it.

First, part of the reason we stick with certain openings and lines is we know those lines and become more familiar and stronger in them. When we switch an opening to spite the opponent, we're taking us out of territory we know best and going down to his level. It evens the game, which gives away a bit of your psychological advantage.

Secondly, the main lines of openings are typically the most critical. If you play a sideline, you're less likely to gain an advantage and the opponent will usually have fewer problems in the opening.

IMO, and from my own experience, it's worth putting in the time and effort to learn the main lines.

It's a perfectly fine strategy. The most popular line is 1.e4 c5 2.Nf3 e6 3.d3, followed by Nd2, g3 etc. It's a bit less popular after 2...d6 or 2...Nc6 from Black, but still fully playable.

Try this:

The Grand Prix isn't dangerous for Black:

Being categorical IS dangerous for a chess player though

It combines well with a Bb5 repertoire since the KIA is pretty solid versus e6 sicilians where you can't really play Bb5.

Nothing is "dangerous" against the Sicilian. Furthermore, he wasn't asking what was "dangerous" against it.

Alapin imo.

i'm working on new theory, using a ferrari engine for analysis. i will disprove this statement.

The world would be a better place if the grand prick were wiped from existance.

KIA, grand prix, alapin all fine club player alternatives to the sicilian. Bb5 seems to have the best standing from GM's - kinda depends at what sort of game you are after.

More open games from Grand prix and most variations of alapin, KIA generally more closed

Bb5 i think tends to more closed, but quite some middlegame positions can arise
