Hello,
is there anybody who has experience in this line?
IF this line works, it would be an elegant solution to the Scheveningen move order, and no reason
to study the Main Line Najdorf just to avoid the Keres.
Against unprepared opponents, the move 6...e5 works rather well and leads to some original positions.
Theoretical issues:
a) 7.Bb5+ Bd7 8.Bxd7+ Qxd7 9.Nf5 h5 10.gxh5 Nxh5, and now the spectacular 11.Bh6!.
Incidentelly, it seems I was the first one who faced this move in a tournament game, some years later it became the main recommodation in White repertoire books.
I think Black is rather Ok after Nisipeanu's 11...g6! with enough compensation in the upcoming endgame.
b) 7.Nf5 h5 8.g5 Nxe4 9.Nxg7+ Bxg7 10.Nxe4 d5 11.Ng3! (11.Nf6+ works very well for Black), and now the original idea is the exchange sac 11...Nc6 12.Nxh5 Rxh5 13.Qxh5 Nd4. Though it has still good statistics, I doubt this is not correct after 14.Bd3!, and it seems there are some guys on ICC who can even convincingly refute this in a Blitz game.
But there are possiblities like 11...Bg4.
Someone has checked this stuff?
