the pawn on d6 was hanging, and that even if White did lose his b3-pawn, there
would be good compensation because of the strong dark-squared bishop. This is
a typical evalution for most King's Indian positions: the dark-squared bishop
is more important than material. Probably, my opponent thought the same way,

{This is GM Aleksandr Lenderman with the analysis of the Game of the Day of
round three at the Gashimov Memorial. And what a sharp battle it was!
Eljanov-Mamedyarov is one of the most epic games I've seen in recent times,
with huge swings in evaluations at critical moments. That's completely
understandable when the position is as complicated this one was. Without
further ado, let's go through it.} 1. Nf3 Nf6 2. g3 g6 3. Bg2 Bg7 4. O-O O-O 5.
d4 d6 $5 {Black opts for the dynamic double-edged King's Indian Defence.} (5...

positions.}) 6. c4 Nbd7 7. Nc3 e5 8. e4 exd4 9. Nxd4 Re8 10. b3 {Eljanov spent
4 minutes here roughly, probably since he already had a game from this
position where he also played 10.b3 against Svidler. However, ultimately he
decided to test Mamedyarov's preparation, which shows how much faith he had in
his own analysis in this line.} a6 $5 {Mamedyarov deviates first. Actually
Mamedyarov had already had this position with Black against Vladimir Kramnik
in a rapid event in Geneva.} (10... Nc5 {was Svidler's choice.} 11. f3 c6 12.

Eljanov, after some thought, deviates from Kramnik's choice. The point of
course is prophylaxis against c5 followed by b5 counterplay. Also this is a
novelty according to my database.} (12. Qd2 {was Kramnik's choice.} c5 13. Nde2

meant Mamedyarov was out of his preparation at this point. a5 is a logical
move though, since now that White played a4, Black has full control of the
c5-square outpost. Possibly it was a little bit more accurate though to start
with ...Nc5.} (12... Nc5 13. f3 a5 14. Ndb5 Nfd7 {and here Black has time to
stabilize his position. His next idea is ...b6 followed by ...Bb7. Also
starting with ...b6 instead of ...Nd7 deserved attention.} (14... b6 15. Qc2 c6

gets Rad1 in, which not only gets his rook in the game, but also prevents the
move ...c6, which would free up Black a little bit. Also the reason why the
rook from the a-file goes to d1, is because on a1, b1, or c1 it has no
prospects, while the rook on f1 might be potentially good on e1, protecting
the center, or f1, helping with a kingside attack.} Bb7 16. f3 Qe7 17. Rfe1

pieces. A great battle, and great comeback by Mamedyarov and great start for
him in the tournament. On the flip side, a very big pity for Eljanov who had
started with 2/2 and came so close to starting 3/3... but one bad move spoiled
it for him.} 0-1
