Stubborn Defense

Fabiano Caruana significantly improved his tournament situation in Shamkir after an important win with the Black pieces against the former world champion Vladimir Kramnik.The Italian GM had to survive at first the strong pressure that his opponent put on him. The moment in which Kramnik decided to open up the game was not chosen right and the tables have turned into Caruana's favour.
A game that I liked (ChessBase 13)

1. d4 Nf6 2. Nf3 {Just like Carlsen the other day, Vladimir Kramnik also
decided to avoid the Gruenfeld.} g6 3. Bg5 Bg7 4. c3 O-O 5. Nbd2 d5 {This is
considered the most reliable move against teh Torre Attack.} 6. e3 Nbd7 7. Be2
c5 {Diagram [#] The Torre Attack represents in this case the reversed Slav
defense. To which Caruana replies with something like a reversed Catalan. My
tongue got reversed as well.} 8. O-O b6 9. a4 {A standard reaction to the
fianchettoe similar to the one that Carlsen used against the same Caruana in
round three.} a6 ({Alternatively} 9... a5 {weakens the light squares and the
pull for White} 10. Bb5 Ba6 11. Bxa6 Rxa6 12. Qe2 $14 {Petrosian,T (2649)
-Gopal,G (2522) Golden Sands 2013}) 10. b4 {White shows aggression on the
queen's flank but his plan is deeper than that. Kramnik wants to force his
opponent to close that side of the board in order to concentrate his forces in
the center and the kingside.} Bb7 11. a5 $146 {Diagram [#] A novelty, in the
spirit of the above-mentioned plan. Previously only} (11. bxc5 bxc5 12. Qb3 {

to keep his opponent busy .} 12. cxb4 b5 13. Rc1 Ne8 {Carlsen already proved
in his game with Mamedyarov earlier that the structure arising after} (13...

find the optimal squares for their pieces.} 15. Ne1 Nc4 16. Nd3 $14 {Diagram
[#] It becomes apparent that White has a lot of small advantages in comparison
to his opponent. To start with- the space advantage. The little pawn on a5
takes away the b6 square from the black Nd7 while the white knights are
feeling very comfortable. White's bishops are also more active and all of
this leads us to the conclusion that Kramnik succeeded with his opening
strategy. Now he starts slowly torturing his opponent. The grand plan is to
prepare and carry out the e3-e4 advance. Caruana's position lacks any
weaknesses, but is passive and it is overall quite unpleasant to play.} Ra7 (
16... Rc8 {is less precise as after} 17. Nbc5 Nxc5 18. Nxc5 {the pawn on a6
will hang.}) 17. Bh4 Ba8 18. Bf3 ({Also interesting is} 18. Re1 {intending
Be2-f1, f2-f3 and later e3-e4 but the former world champion prefers a more
aggressive set up.}) 18... Nf6 19. Qe2 Ne8 20. g4 $5 {[%cal Gh4g3,Gf3g2,Rf2f3,

further advance of the f and e pawns.} Ned6 21. Bg2 Qc8 22. Nbc5 Re8 23. Bg3
Qd8 {Caruana prepared his position as much as he could for the possible
assault.} 24. Rcd1 ({White could have also provoked a weakening with} 24. Be5

Kh1 Bh6 {Black does not want to change the pawn structure and play with
isolated pawn after} (26... e5 $5 {but this definitely interesting.}) 27. Nf4 {
The time trouble is approaching and Kramnik decided that this is a good moment
to complete his idea. However, as he later confessed at the press-conference
he missed an important tactical detail.} ({He did not like} 27. Bf2 {due to} f5

risk after say} 28. Ne5 fxg4 29. Nxg4 Bg7 30. e4) 27... Nb7 28. Ncd3 {Or else
Black might take on c5 and put his bishop on c6.} Nd8 $1 {Strong maneuver
before the decisive central clash.} 29. e4 Nc6 $1 {Diagram [#] The point. Now
it is not clear who attacks more.} 30. exd5 (30. Qf2 {simply loses a pawn} Nxb4

into life and his position is stronger now.} fxe6 ({Even better was} 32... Qf6

are too many weaknesses in White's camp and he tries to compensate with
kingside activity.} 34. h4 Rf7 ({Kramnik suggested a more simple alternative}

What I'm wondering is Cheap Archeage Gold why no manufacturer produces a device this size with, say, 16 SD card slots in it Buy Archeage Gold and a RAID controller, a ram buffer and a coin cell battery. You would get great speeds, get to choose how much capacity you want, and when a card or Archeage Gold battery dies, you just replace it.
