1. d4 d6 2. c4 e5 3. Nc3 $5 {The other knight move to f3 is definitely played
more often but I think this move will gain in popularity after this game.} (3.
dxe5 dxe5 4. Qxd8+ Kxd8 {is a pretty toothless endgame for White. He cannot
count on an opening advantage here.}) 3... exd4 {This has been the most
popular choice. Black can maintain his centre without taking on d4 but it then
allows White to develop normally.} (3... Nf6 4. Nf3 {and now the wisest might
be to convert the position into an Old Indian with Nbd7.} Nbd7 (4... e4 5. Ng5
Bf5 6. g4 Bxg4 7. Bg2 $14) 5. e4 $14) 4. Qxd4 Nc6 {With the move 3.Nc3 White
forces Black to give up the centre with 3...exd4 and in return, Black gains a
tempo with Nc6 attacking the queen. So the long term trump of more space lies
with White while the short term advantage of a lead in development is on
Black's side.} 5. Qd2 g6 {This is the normal way of developing the bishop. But
considering how the game continued, Black might want to look for improvements
here.} (5... Be6 $5 {And here we have another game of Erwin himself.} 6. b3 a5
(6... Nf6 {threatening d5.} 7. e4 g6 8. Bb2 Bg7 9. Nf3 O-O 10. Be2 a5 11. O-O
a4 $132 {and even though White has a good space advantage, Black has been able
to create some counterplay on the queenside.}) 7. Bb2 a4 8. Nd5 $5 {I wonder
if this was Erwin's preparation.} axb3 9. axb3 Rxa1+ 10. Bxa1 Bxd5 11. cxd5 $14
{White has not only the double bishop advantage and but also lot of space.} Qa8
12. Bc3 Ne5 13. f4 Nd7 14. g4 $6 {With this White went a little overboard.} ({
The normal way would have been} 14. Nh3 Ngf6 15. Nf2 Nc5 16. e4 $1 Nxb3 17. Qe3

(2640)-Belkhodja,S (2432) Dieren 2013}) 6. b3 {This is the most common way to
play. The bishop on b2 will try to nullify the powerful bishop on g7.} Bg7 7.
Bb2 Nf6 8. g3 O-O 9. Bg2 Re8 {This is all very standard. You can see that
Black has almost completed his development while the white king is still in
the centre. If Black can get in the d5-break, he will cause huge problems for
White.} 10. Nf3 $1 {Erwin develops the knight towards the centre. As Erwin
mentioned in an interview for ChessBase, "My computer gives White a pleasant
edge after 10...Bf5 11.Nh4! with the point that 11...Ne4 can now be met with
12.Bxe4 Bxe4 13.f3! Therefore, Black has to retreat his bishop but then White
has a risk-free game. I wouldn't mind repeating this line."} (10. Nh3 {was my
choice when I reached this position with the white pieces in a recent game in
Al Ain Open 2014.} Bf5 {was played in the game and after} ({Black could have
got a huge initiative by playing} 10... d5 $1 11. cxd5 $6 (11. Nxd5 Bxh3 12.
Bxh3 Ne4 (12... Nxd5 13. Bxg7 $14) 13. Qc2 Nd4 $13 {leads to crazy
complications!}) 11... Bxh3 12. Bxh3 Nxd5 13. Nxd5 Bxb2 14. Qxb2 Qxd5 15. O-O
Qh5 {and Black wins the e2 pawn. White has enough compensation to maintain the
balance but there is not a trace of an advantage.}) (10... Bxh3 {is same as 10.
..d5.}) 11. Nf4 $1 $14 {Sagar Shah-Hojjatova Aydan, Al Ain Classic 2014, (1-0).
White had a very pleasant position.}) 10... Bf5 (10... Ne4 11. Nxe4 Bxb2 12.
Qxb2 Rxe4 13. Ng5 Re8 14. Ne4 $36 {does cause some problems to Black.}) (10...
d5 $2 11. Nxd5 Nxd5 12. Bxg7 Kxg7 13. cxd5 $16 {simply loses a pawn.}) 11. Nh4
$1 {A very important move if White is trying to secure an edge in the position.
} (11. O-O $6 {This natural move would allow Black to equalise quite easily.}
Ne4 $1 12. Nxe4 Bxb2 13. Qxb2 Bxe4 $11 {would lead to bland equality. Black
has no problems because he has got rid of the key c3-knight and the f3-knight
is far away from the crucial d5-square.}) 11... Bd7 (11... Ne4 $6 12. Bxe4 $1 (
12. Nxe4 $6 Bxe4 13. f3 Bd3 $1 $17) 12... Bxe4 13. f3 Bf5 14. Nxf5 gxf5 15. Nd5
$14 {Black's pawn structure is ruined and White has a clear advantage.}) (11...
Be6 {was the choice of MVL against the better half of Erwin L'Ami.} 12. O-O a5
(12... d5 $2 13. Nxd5 Nxd5 14. Bxg7 Kxg7 15. cxd5 $18) 13. Rac1 Nd7 (13... a4
$6 14. Nxa4 $14 {The rook on c1 prevents Bxc4.}) 14. Nd5 Nc5 15. Bxg7 Kxg7 16.
Qb2+ f6 17. Rfd1 $14 {looks like a pretty pleasant position for White.}) 12.
O-O Qc8 {The main problem that Black faces is the lack of space. He hasn't
been able to make use of his lead in development and White has finally caught
up. I would assess this position as being slightly more pleasant for White to
play.} ({Another game by Alina L'Ami continued.} 12... Rb8 13. e4 (13. Rad1 $14
) 13... Nh5 $6 14. Nd5 Be6 15. f4 a6 16. Bxg7 Nxg7 17. Qc3 Bxd5 18. cxd5 Na7
19. f5 $16 {1-0 (58) L'Ami,A (2393)-Ionica,I (2157) Calimanesti 2014. White
had a clear advantage.}) 13. Rfe1 $1 {White keeps pieces on the board as he
has more space. Now Bh3 can be met with Bh1 keeping the bishops.} Bh3 14. Bh1
Qg4 {True to his style Mamedyarov goes for active play.} (14... a5 15. Rad1 $14
{Once again the entire White setup simply looks more cohesive.}) 15. Ng2 (15.
Rad1 {Preventing ...Qd4 would have made the queen look pretty silly on g4.} Qh5
16. Nd5 Nxd5 17. cxd5 $16) 15... Qd4 16. Rad1 Ne4 $6 (16... Qxd2 17. Rxd2 {
was relatively better. Now after} Bf5 18. Nf4 $14 {White definitely has a
pleasant position thanks to his knights coming to d5 but Black can keep
fighting.}) 17. Qxd4 Bxd4 (17... Nxd4 18. Nxe4 Rxe4 19. Rd2 $1 {the black
pieces are extremely clumsily placed. Nf4 is a huge threat.} Ne6 20. Bxg7 Kxg7
21. Nf4 Rxf4 22. gxf4 $16) 18. Rxd4 $1 {A very strong exchange sacrifice by
Erwin.} Nxd4 19. Nf4 {Attacking the bishop on h3 and unleashing an attack on
the e4-knight.} Ng5 $6 (19... Bd7 20. Nxe4 $18) (19... Nxc3 $1 {was the only
way to minimise White's advantage.} 20. Bxc3 g5 $1 {would have kept Black in
the game.} 21. Bxd4 gxf4 22. Bxb7 Rad8 (22... Rab8 23. Bc6 $16) 23. f3 {
Threatening to trap the bishop with g4.} (23. Bc6 Bd7 $11) 23... fxg3 24. hxg3
$14 {White has ample compensation for the exchange and stands better here
thanks to his two powerful bishops.}) 20. Nxh3 Nxh3+ 21. Kf1 {At first this
seems like an illogical resignation. But on closer inspection, things start
becoming clearer. The b7-pawn is hanging. Ne4 is threatened which attacks the
d4-knight and threatens Nf6+. The two bishops are so powerful that White will
inevitably emerge with a crushing advantage.} (21. Kf1 Kf8 (21... c6 22. Ne4
