I've never played 8...e5 in my life so I thought I should stick to stuff I'm more comfortable doing myself.

8... e5 is the other major option. 9. d5 c6 10. h4 This has been played in a variety of high-level games and was seen, for instance, in the Anand-Gelfand match. It's a very interesting position and one that's a lot of fun to analyse.

9. O-O-O ♕d6 This is by far the most topical move in this position, and something I've encountered with both colours. I had this position with White against Fabiano Caruana and with Black against Wang Hao in Stavanger in 2013. White has a variety of options.

9... f5 To be honest with you, my original intention was to recommend this move, which I've been playing for a number of years. I even began that video, but then I ran into some very serious chess problems equalising after 10. e5 , so the idea had to be scrapped. Perhaps some day I'll film a video explaining why I think this line is a bit of a problem for Black, but for now we'll concentrate on the alternative.

10. h4⁈ The two main moves in this position, 10.Kb1 and 10.Nb5 , will be covered later, but this is quite a serious possibility. In general, the whole point of the 3.f3 line is to castle long and try and give mate, which distinguishes it from the normal Grünfeld fare where White is perhaps more concerned with positional advancement.

10. d5⁈♘e5 drives the black pieces towards the squares they want to occupy. The computer even suggests playing 11. b3 here, which is a good indication that something has gone badly

wrong. 11... f5 ( 11... ♕a3+12. ♕b2 ♕xb2+ 13. ♔xb2 f5 )

10. f4⁈ isn't particularly good either. 10... ♗_{g4 11.} ♘_f3 ♖fd8 12. d5Otherwise the centre is about to fall. 12... ♗xc3 is probably the most practical solution, and Black's response is the same regardless of how White takes. 13. ♕xc3 ( 13. bxc3 e6 ) 13... e6 Once again the white centre is under immediate attack and Black is doing fine. 14. ♗_c4♘_{xc4 15.} ♕xc4 exd5 16. ♖_xd5 ♕_e7

10. e5⁈♕b4 is completely counterproductive for White, as it drives the queen directly to the squares it wants to occupy. Nc4 will now be a constant threat, as will Rd8, and the bishop has a fantastic square on f5.

10... ♖d8 After this move White has to pay attention to the centre.

11. ♘_b5

11. d5 ♘e5 is once again not particularly attractive for

White. 12.♕f2 ( 12. ♘b5 ♕d7 13. ♕c2 c6 14. ♘xa7 ♖xa7 15. ♗xb6♖xa2 ) 12... c6 13. dxc6 ♕c7 11... ♕d7 12. h5 a6 13. ♘c3 We're following a game Grischuk and Mamedyarov played in 2010.

13... ♗xd4 The much more practical decision.

13... ♘xd4 was the move played by Mamedyarov, which after 14. hxg6 fxg6 15. g4 led to an incredibly crazy position which I think is objectively quite ok for Black, but requires a lot of knowledge and precise

"computer-like" play.

14... fxg6 15. ♘_d5⁉ The critical move in this position. Black can reply in a variety of ways.

15. ♗xd4 ♕xd4 16. ♕f4 ♕f6 ( 16... ♖f8⁉ 17. ♕xc7 ♕b4 18. a3♕c5 19. ♔b1 ♗e6∞ ^{) 17.} ♖xd8+ ♘xd8 18. ♕_xc7 ♗d7 , and Black is fine.

15... ♘_xd5

15... ♗xe3 is the one "wrong" solution: 16. ♕xe3 ♕e8 At the moment the Nxc7 fork is impossible because of the queen check on d8 after exchanging rooks on d1, but if White finds 17. ♗e2! Black's position is somewhat dangerous, because now Nxc7 is a huge threat, and

after 17...♘xd5 18. exd5 ♘_{b4 19.} ♕b3 White gets a lot of initiative on the kingside after driving the knight away from b4. 19... a5 20. a3 ♘_a621. ♘_h3 ♗_{xh3 22.} ♖_xh3+/=

15... ♗g7⁉ is a very decent alternative for Black, although time constraints mean I'm not going to go into any detail about it here.

16. ♗c4 The point of the previous play.

16. ♗xd4 is a somewhat naive move which runs into 16... ♘_b6! and Black is just perfectly fine. 17. ♗e3 e5=/+

16... e6⁉ The most practical solution.

16... ♗_{xe3 17.} ♕xe3 e6 ( 17... ♘b4 18. exd5 ♕f5 19. ♗b3+/= )18. exd5 ♘a5 is fine for Black, but after 19. ♗d3 exd5 and the somewhat strange-looking 20. ♗_e4! I think White has enough compensation for the pawns he had to sacrifice:

a) 20... ♕f7 21. ♗xd5!♖xd5 22. ♖xd5 ♘c6!∞ ( 22... ♕xd5?23. ♕e8+ ♔g7 24. ♕e7+

♕f7 25. ♖xh7++− )

b) 20... d4 21. ♕_g5 ♘_{c6 22. g4} ♕_{e7 23.} ♘_h3=/∞

16... ♗g7 also allows unnecessary complications: 17. ♘_h3⁉ ( 17. exd5♘e5 18. ♗b3 a5 is very good for Black. ) 17... e6 18. exd5 ♕e7 19.♘f4⇆

17. ♗_xd4 ♘_{b6 18.} ♗xb6 Forced.

18... ♕_e7! Perhaps even stronger than just exchanging queens, as after

19. ♕_e3 ♖_{xd1+ 20.} ♔xd1 cxb6 Black has a safer king and is currently a pawn up. White can regain the pawn at the cost of tempi by playing

21. ♕xb6 but after

21... ♘e5 Black gets his pieces to good squares and is doing perfectly fine.
