variation. And in any case accepting a slighlty cramped position with Nbd7 is
in the spirit. On the other hand, black rules out the possibility of playing
the Mar del Plata variation. } (6... e5 7. dxe5 { annoying in my opinion } (7. O-O Nc6 8. d5 Ne7 { and this is quite a crazy line, impossible to
play without serious preparation. }) 7... dxe5 8. Qxd8 Rxd8 9. Bg5) 7. O-O e5 { Now white has three main alternatives. Exchanging on e5, which looks
a bit senseless; moving to a petrosian structure, claiming that Nbd7 is worse
than Na6 as usually played there; keeping the tension } 8. Re1 { probably the most
precise to keep the tension, since Be3 allows Ng4 (although it can be on
purpose) } (8. dxe5 dxe5 { [%draw arrow,c7,c6] [%draw arrow,d8,e7] now this is still
playable for white, but it does not make much sense. }) (8. d5 { see different file }) (8. Be3 Ng4 (8... Re8 { quite surprisingly this has been the favorite move, also by
several king's indian experts. } 9. d5 { logic: what is now Re8 doing? } (9. Qc2 c6) 9... Nh5! { if Nf4,Bxf4 then Re8 would be okay } 10. g3 Bf8! { and this is

opening the center exd4 (mainly because the rook can come over quickly to the d

probably important to start with Qe7, because the a- pawn should not be
touched, since in many variations black will play c5, white will attack with b4

to do so! Actually, a lot of moves are possible here, but the problem is that
white can keep the tension on, with moves such as Bf1, and if black tries to
also to play waiting for white to close the center with d5 and then start the
counter attack with f5, he will find himself with some weakness (for example,
he would have played a6, or c6 meanwhile). } (8... c6 9. Bf1!? { continuing the waiting game and passing the ball to black. } (9. d5 { it has to be studied to understand how to react the the d5 push
when a pawn is already on c6 }) 9... h6!? { !!? A strange looking move, in this strange looking waiting game.
The explanation is quite deep, indeed. Basically, at this point black can
choose whether to open the center (suggested by the computer with even chances,
roughly speaking) or to pursue a classical fight with closed center and
planning f5. In the latter case, after having tried several moves order and
different plans, the best option for black looks like to not move the queenside
pawns, and preparing the kingside expansion by playing h6. } (9... exd4?! { this is definetely playable, but if white plays precisely
he will keep a space advantage and some pressure. If black's idea is to give up
the center then it's better to do it without c6 }) (9... a5 { is the most played in this position. However, with the
queenside weak white can try to exchange the central pawns. } 10. dxe5 dxe5 11. Qc2 Qe7 12. Na4 $14) (9... a6!? { An interesting option, among several of them. The computers
like exd4, in order to gain some squares for the black knights, but I think
that only white can be better, thanks to the space advantage. Moreover, if
black really wants to take d4 (as general strategy), he should do so without
c6. } 10. d5 { [%draw full,d7] this is always the favorite by the computer, which
likes white space advantage. At this point black's problem is how to carry on
the standard plan with f5 even with the stupid-looking Nd7 (which should be in
e7)? } 10... Ne8!? { crafty move. To understand it, look at the variation starting
with 10...c5: in short, black waits one tempo before to close the center, in
order to see what is white reaction } (10... c5 { it has been played successfully, and is perhaps the most
coherent. No need to say stockfish hates black position after this. Admittedly,
Nd7 looks weird (should be in e7) } 11. a3 h6 { it does not feel correct. } 12. Bd2! { [%draw arrow,d1,c1] } 12... Ne8 (12... Nh7 13. Qc1 { [%draw full,h6] }) 13. Qc1 Kh7 14. b4 f5 15. exf5 gxf5 16.

close to equality } 11. cxd5 (11. Nxd5 Nxd5 12. Qxd5 Nf6 13. Qd3 b5! { one line where a6 is useful! } 14. cxb5 axb5 15. Qxb5 Ba6) 11... b5!))) (8... Qe7! { using a similar strategy such as after 9.Qc2, black prepares
the field for closed center and opposite flank attack. } 9. Bf1 h6!? { and now it looks like white ran out of waiting moves. } 10. d5 (10. Be3 Ng4) 10... a5 { with typical structure (see different file) }) 9. Nxd4 Re8 { Despite some exchange, this position is very complex. Black
needs to know where to place his pieces, or he can easily end up with a very
bad position (due to d6). On the other hand, if he knows the way then he can
achieve nice piece activity, and fair chances to take over the initiative. } 10. Bf1 (10. f3 Nh5!? 11. Be3 (11. g4 Qh4! 12. Rf1 Ng3 13. hxg3 Qxg3+ 14. Kh1 c5! { the key move } (14...

stockfish. Black lures white king in the corner before to play Qf6. Against the
