I love Alekhines defence as black, can you share with me what it's disadvantage and it's wakeness of using this kind of defense. what its primary goal?..

It is known as a hypermodern defense, which means it does not immediately necessarily occupy the center with pawns.  There are several sharp lines with it that can leave white in a horrible position. I play it all the time, and absolutely love it!  The chase variation is, of course, my favorite.  I strongly dislike when white refuses to challenge the N on f6 LOL! 

Heh interesting. You say you love that defense but unaware of its goals and disadvantages? this puzzles me... developing such an opinion before knowledge about it is known... That's my opinion of the matter.

  In Alekhines defense, black is willing to concede the center to white early on. Black's plan is to attack white's central pawns once they are fix on advanced positions.

The fact that white will have a greater central control for a big part of the game often means that black will find it a bit harder to maneuver. That's part of the reason it's extremely rare among top players. Has been extremely rare to non existent among them for dozens of years. It's not unplayable though.

The "Alekhine's crux" is said to be: "Are the pawns strong or weak?" (the white pawns on d4 and e5). It seems that if white knows what he's doing he can maintain them.

Alekhine thought the best attempt against this opening is the four pawn attack, but the reason it is hardly played is not that at all, but rather that white tends to keep an edge with simpler lines without using the f and c pawns early on.

1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 is the variation keeping black from playing it more often. Even by exchanging immediately with 4...dxe5 5.Nxe5 white just seems to have a central advantage for no compensation.

If black avoids this exhcange in order to keep better chances for attacking white's pawns later, he has to accept a more cramped position. Playable, but not easy.

wow! you have a capacity to write a book, well expained thank you!

to me Alekhines defence i love it, because it has an extra tempo and increases my stealth counter chances to white is the middle and end game. dispite for the more chance of cramp position youve said...

Teddy, kulbaa da. grabe ang English. :-D

cris pg-puyo diha wala man imo...

I play the Alekhine's often, and my opinion is that like certain variations of French, KID, Centre-Counter etc, even if the theorotical evaluation is + =, the black player will usually find himself in a familiar position which should be more comfortable for him than it is for his opponents, because, more likely than not, the white player would not have even heard of 1.e4 Nf6. In fact, most likely or not, you will not even know that the book gives a particular position a + =.

BTW, grolich, GM Lev Alburt is the man who all Alekhine's Defense fans have a statue of in their room. Lev Alburt refuted many so called refutations, and thought up of plenty of new ideas, including the sharp and exciting Alburt variation of 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 (Modern variation).
