All games have started, so we can have an overview of the variations played.
In the 15 games of the first round, white's replies to the najdorf were:

6. Be2 (Classical Najdorf): 6 games (40%). This is supposed to be a 'quiet, more positional' line (Wikipedia). Played succesfuly by Karpov.

Black's answers were: 6... e5 (4), 6... Nc6 (1), 6... e6 (1)

6. Bg5 (Old main line): 4 (27%). Obviously the sharpest answer for white. 

Black's answers were: 6... e6 7. f4 Be7  (2), 6... e6 7. f4 Qb6 (1 - This is the notorious Poisoned Pawn variation), 6... e5 7. Nb3 Be7 (1)

6. Be3 (English attack): 4 (27%). This is supposed to be the most popular line currently.

Black's answers were: 6... e5 (3), 6... e6 (1)

6. Bc4 (Fischer-Sozin Attack): 1 (6%). Named after Bobby Fischer, that used to play it with success.

Black's answer was 6... e6

Hopefuly, aside of playing, this tournament can become a good opportunity to discuss a bit on this beautiful variation.

I will try to sum the games up with some statistics on the sub-variations that will be used.

Thanks for joining, and have some great games everyone!

Hi all. I ve played Najdorf for several years it is one of my favorits mainly beacause it leads to very sharp positions,  really difficult to count even the variation tree. I ve abandoned it for a while, so its a good chance to play again- lets do it!

Hey G_Odd and thanks for joining. 

If you play the sicilian, you must familiarize yourself with the Najdorf. It's my personal first choice defence, but that doesn't mean I feel really comfortable with it - I seem to lose more games than I win with it.

Hence the tournament...

This should be a practice, I never play this defence (I do not recall I did...). Let's have some nice games though.
