One of the most fascinating positions I have seen on a chess board. 7...b5 is really a fantastic variation. The game ended in a draw a bit later on but the possibilities are endless for black. (I had played 17...Rb5)

And I am playing a new game with Observer, one of the top 5 players of this site, with the same position again. I try to post it when it's finished.

 
 
2 remarks:
There's no reason to accept a draw after 17.Rf1, as White's chances are clearly better.
And 2nd try 14.Qd3 instead next time you're playing this line, as after this continuation I won't give a dime for Black.
See: 14.Qd3 gxf6 15.Bxf6 Rg8 16.0-0-0 Rxg2 and now 17.Kb1 Qb7 etc. gives White a decisive advantage. Or 16...Rg5 17.Ne5 etc.
 
No offence:-)
 

Or 16...Rg5 17.Ne5 etc.
 
Sorry typo: Of course 16...Rg6 17.Ne5 Rxb5 18.Nxg6 Bh6+ 19.Kb1 etc.

Ok challenge me my friend we can all have a laugh

Ok buddy, start laughing then,but don't forget:
"He laughs best who laughs last."
 
I will challenge you.

If you win any of these games (14 Qd3) and (17 Rf1) I will eat my hat.
If you give any of these positions to analyse to a strong program like Fritz or Rybka, it will tend to prefer white. Why?
 
-White has an extra pawn.
-White is much better developped.
-His king looks safer whereas black king is stuck in the middle of the board.Many pins also against black, the knight d7 can't move and the d8 square is very weak.
 
Despite all these drawbacks I am convinced that black can survive and even create winning chances.
 
-Most of the blck pieces are still on their original squares, but white has a lot of weaknesses because of their risky play. The 2 black bishops will be extremily active sooner rather than later.
 
-The 2 black rooks are hyperactive as well and control 2 important colums, the "A" one leading to the white king and the "G" one , possibly the most important one in the Najdorf in terms of counterchances.
 
-The "awkward" position of the black king is not as bad as we think. This king can seek shelter on both sides of the board. It has got great flexibility.
 
Having said that I think we can say the position after 10...b4 is dinamically balanced but any mistakes from one side should be exploited with an instant win by the other side.I will post some of the games I played soon.

Well so far the 14 Qd3 "killer move" hasn't got the expected result, white had to force a draw to avoid defeat.

 
I believe that an interesting variation might start at move 20:
20 Rxd7( it is evident that 20...Qxd7 is bad and 20...Re1+ 21 Rxe1 leaves white in a better position), therefore
20...Kxd7 21 Qa4+. Black has two valid options(anything else seems to be weaker)
A) 21...Kd8 22 Bxe5 Qxe5 23 Qe8+ when the bishop at f8 falls;
B) 21...Kd6 22 Qa6+ Kd7 ( all other moves by black K seem dangerous)
23 Bxe5 Qxe5 24 Qb7+ Ke8 25 Rd1 leads to the capture of the bishop in f8.
 
Indeed, the position is immensely beautiful and rich.
Hopping that I do not have too many mistakes, please analyze this observation.
 
All my best, Kastelka

Thanks for your efforts however your B)-line is incorrect and so far confirming my decision for not to play Rxd7 what I indeed was looking at during the analysis:
 
B)20.Rxd7 Kxd7 21.Qa4+ Kd6 22.Qa6+ Kd7 23.Bxe5 Qxe5 24.Qb7+ Qc7! -+ leading to a lost position for White.
 
Geierwally

 You are right!
Thank you for check it out!
Kastelka

For chess players who like unclear positions and wild complications this variation is a must see. Artistic in a way.

After 22 Qa6 Kd6 white can repeat the moves and force a draw . Too risky for black to try something.
 
But after 14 Qd3 black can improve with 14...Qb7!

 
On this game I think my opponent forgot his queen was not on d3 but on e2, and made the dubious move 16 0-0-0?! when 16...b3! allowed black to swap queens and have a very good endgame with 2 powerful bishops.

I offered a draw by mistake but after 50 Kd3 Rg4 black still has good chances.

Well so far the 2 games I played with GeierWally are very good. In the 14 Qd3 my fellow player is fighting for a draw and he should get it soon.
 
In the 17 Rf1 one, he will have to be more lucky . More when we finish the games.
