The Argentinian Defence

The Scoresheet : 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6! 6.Be3 e5 7.Nb3 Be6 8.f3

We call this defence the Najdorf because of the Argentinian Super Grandmaster from the 50's 60's Miguel Najdorf. After 5...a6 we get this caracteristical scheme. In fact, instead of playing some classical developpment blacks prefer keep the possibility of b5. Why??

2 reasons
- counter the central square control (d5) with sometimes b5,b4
- counter the longcastle by an early queenside attack

The so many games played in this opening prooved that this is a weapon to take care. With f3, my intention is Queen d2 long castle & g4, the most direct solution

So Be Careful...
