Mamedyarov and Durarbeyli used this variation in their arsenal} 11. Bg5 {

ready for a fight or not. Also it was a novelty in classical games, although

position seemed for me to be quite sharp and it requires accurate play from
both players. That was the main idea why I chose Deffered Cozio} 21. Rac1 Re8

and spent quite a long time on finding the correct path to keep the balance in
position} Re4 ({another reasonable option was} 22... Re6 23. Qd3 Kb7 24. Rc4 {

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nge7 {After a couple of encounters with
Jonathan in the Spanish this was no great surprise. Although he hadn't played
this move in this specific position beforehand the ideas are similar to the
ones after 4...g6, which he chose against me last time.} 5. c3 g6 6. d4 exd4 7.
cxd4 b5 8. Bc2 ({During the postmortem Tisdall mentioned the option} 8. d5 $5 {
as interesting. This has actually been played once following} bxa4 9. dxc6 Nxc6
{Here White has a few options at his disposal and this could definitely be
worth further investigation.} {The game from the database continued} 10. Qxa4 (
10. Nc3 $146 {This new move playing for quick development looks more
interesting to me as I think White really needs to do something pretty quick
in order to achieve an advantage. At the moment Black's position is slightly
vulnerable with moves like Nd5 and Bg5 coming up. A possible continuation is}
Bg7 11. Bg5 f6 12. Bf4 {when White has managed to close Black's bishop
diagonal and seems to have at least some minimal pressure.}) 10... Bg7 11. O-O

0-1 (36) Grover,S (2515)-Dzhumaev,M (2485) Visakhapatnam 2011. This complex
position offer mutual chances but I would personally prefer Black here as he
has the long term trump of the pair of bishops.}) 8... d5 {The most logical
reply in my opinion. However} (8... Bg7 {is slightly more popular. Now there
might follow} 9. d5 Na5 10. Bd2 $1 {when White's score is huge. The tactics
work out well for White and Black will likely end up in a passive Benoni-like
position.} c5 (10... Nc4 11. Bc3 Bxc3+ 12. Nxc3 $14 {gives White a very strong
grip on the dark squares.}) ({Of course} 10... Bxb2 $146 {will only lead Black
into further difficulties after} 11. Bxa5 Bxa1 12. Nc3 {when White's activity
more than compensates for the exchange.}) 11. Bc3 $14) 9. exd5 Nxd5 (9... Nb4

continuation} f5 15. Bc2 Na5 16. Re1 O-O 17. Ne5 $14 {when White holds an
advantage.}) 11. Nc3 $146 {This move was played in the belief that I was still
following my preparation. However this appears to be a novelty at this very
moment. A fully playable move but not the most testing for Black.} ({Instead} 
11. Bg5 $1 {is to be preferred putting Black under immediate pressure while
his king is still uncastled. Now Black has a few options to chose from.} Qd6 {
This has been played successfully by Iordachescu and is slightly more popular
than the others although the position in general is rather unexplored.} (11...

a decisive advantage as Black will either lose material or be preented from
castling.} Be6 (16... Bf6 17. Bh6 $18 {Althouugh the material is still equal

Grandelius. However the alternatives are also interesting and it's hard to
give any clear favourite.} ({The move order} 12. Nc3 {was chosen by Adams but
leads to the same thing as Nbd2 after} O-O 13. Ne4 {transposing.}) ({However} 
12. Re1+ {is an independent option forcing Black to part with his bishop
before castling.} {Following} Be6 13. Nc3 Nxc3 14. bxc3 O-O 15. Nd2 Bd5 16. Ne4
Bxe4 17. Bxe4 $14 {White was better in 1/2-1/2 (47) Nijboer,F (2546)-Arnaudov,
P (2439) Dieren 2011. The pair of bishops secure an edge although Black is
pretty solid.}) 12... O-O 13. Ne4 Qd7 14. Re1 $1 {A strong flexible move which
slightly improves White's position while giving Black several ways to step in
the wrong direction.} (14. Bb3 {played by Adams is less critical although after
} Na5 15. Ne5 Qe6 16. Bxd5 Qxd5 {his position was promising in 0-1 (52) Adams,
M (2723)-Iordachescu,V (2636) Konya 2012. Now instead of the immediate Nf6+ he
should rather have gone for} 17. Qf3 $1 $146 Bb7 18. Nf6+ Bxf6 19. Qxd5 Bxd5

losing.} Kh7 18. Rc1 $16 {White was clearly better and probably already even
winning in: 1-0 (45) Grandelius,N (2576)-Tomazini,Z (2277) Kocaeli 2013} {
After the continuation} Na5 $2 {White's best would have been} 19. Bxd5 $146
Qxd5 20. Nd3 $18 {when White's activity and the many threats provide a
decisive advantage, e.g.} Bb7 21. Rxc7 Rac8 22. Rce7 $18) 11... Nxc3 (11... O-O
{was an alternative option. There might follow} 12. Bg5 Qd7 13. Re1 {with some
slight pressure for White.}) 12. bxc3 ({Now the intermediate move} 12. Re1+ $5
{was worth considering following} Be6 13. bxc3 O-O {when Black's bishop has
been forced to e6 compared to the game. Now one exciting continuation for
White is} 14. Ba3 Re8 15. Rxe6 $5 fxe6 (15... Rxe6 16. d5 $14) 16. Be4 Qd7 17.
Ng5 {when White's active piece play offers him full compensation for the
sacrificed material.}) 12... O-O 13. Re1 Bb7 14. Bg5 $1 {A good active move
trying to provoke the weakness ...f6 which would put the black bishop on g7
under a cloud.} Qd6 $6 {This appeared to be a rather unfortunate square for
the queen.} ({Instead} 14... Qd7 {looks somewhat better although here too
White has some initiaitve.} 15. Qd2) 15. Nd2 $1 {This knight manoeuvre to e4
secures an advantage for White.} Rae8 16. Ne4 Qd5 {Black hopes to achieve
counterplay along the a8-h1 diagonal and also creates the threat of ...Rxe4.
Here The position is full of options for White but during the game nothing
appeared to be very clear to me.} 17. Qd2 {White protects the bishop on g5 and
slowly builds up an attack. Now Nf6 might also soon become possible.} (17. Qf3
{might lead right into an endgame following} Na5 18. Nf6+ Bxf6 19. Qxd5 Bxd5
20. Bxf6 {when the game is about equal. White has the pair of bishops and has
a bind on the kingside but Black's light square control on the queenside
compensates.}) ({The forcing move} 17. Bb3 {would only help Black after} Qf5 {
and now} 18. g4 $2 {is a bit too optimistic as Black will soon achieve
dangerous counterplay agianst White's open king.}) (17. Bh6 {is a tactical way
to exchange off the dark squared bishops but does not look too critical for
Black after} Na5) 17... Na5 $6 {This might look logical in a way opening the
diagonal towards g2 and heading with the knight for the c4-square. However the
knight gets a bit offside and White receives a dangerous initiative.} ({Here}

directly puts White under pressure. However there is a a good reply} 18. Bf6 $1
bxc3 19. Nxc3 $36 {keeping the initiative.}) 18. f3 {A slight weakness but
also a necessary move in order to give freedom to the white pieces. Now Nf6+
becomes a serious threat.} f5 {A logical reply in a way but it also weakens
Black's king and he soon end up in difficulties.} ({The alternative} 18... Re6
{also look troublesome after} 19. Nc5 ({or} 19. Bh4 $36 {with a continuous
strong initiaitve.}) 19... Rxe1+ 20. Rxe1 {Black is under heavy pressure and
the best seems to be grabbing the pawn with} Qxa2 {after which.} 21. Nd7 {
wins an exchange, e.g.} Nc4 22. Qe2 Qa5 23. Nxf8 Bxf8 $14 {with an obvious
advantage for White although Black is not without chances.}) 19. Nc5 b4 20.

the diagonal h8-a1. However there was something even better available.} (21.

would have kept the game in balance.}) 24. Kh1 $1 {A strong move which is easy
to underestimate in time trouble.} Bb5 $4 {A serious blunder which loses
immediately. However Black's task was already difficult.} (24... Qxd2 {was to
be played when after} 25. Bxd2 Nc4 26. Bf4 a5 $14 {Black can still fight for a
draw.}) 25. Qxd4 Bxd4 26. Ne6 Nc6 27. Bb3 Bc3 28. a4 {Now a piece will be lost

{This game was played in the 3rd round of the Dutch championship 2018 in
Amsterdam. The win in this game allowed me to take the lead in the tournament
with 2.5 points out of 3.} 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 b5 5. Bb3 g6 {
My opponent in this game Ivan Sokolov is a very experienced player. We had
played a huge number of games before that one. But here Ivan manages to
surprise me choosing an obscure modern line of the Ruy Lopez. I was expecting
a much more solid choice here. This variation is becoming popular due to the
practice of S. Mamedyarov.} 6. a4 {Since I was not familiar with the recent
theoretical developments of this obscure line, knowing only the traditional 4..
.g6, I decided to compare the positions with and without inclusion of the
moves b7-b5, Ba4-b3. And, of course, punishing my opponent for such strange
play in the opening came into my mind. White has a development advantage, and
when one has the advantage in development it is necessary to open the position
and play for attack. This is what I was trying to do in the coming moves!} b4 {
