equal yet very imbalanced endgame. White has a 5v3 majority on the Kingside

one interesting detail: 6.Bg3 was favored at the same time by such giants of

third and much less popular 6.Bd3 scores even higher: almost 64%. The breakup
of White's pawn structure after 8. ... Bxf4 9.exf4 in this case is only

standard plan for it, mostly due to its pawnless center, lack of apparent
weaknesses, and the direct contact between the pieces of the sides. For that
reason, playing such positions may be formidably difficult for both sides,
notwithstanding which side has the initiative. Yet one can formulate some
general strategic guidelines for playing them: a battle will be of a tactical
nature, there is no room for lengthy maneuvers. Every move preferably should
either create a direct threat or defend from it, or do both if possible. The
crisis and transformation may occur very quickly, and because there may be
lots of reasonable alternatives and complications, mistakes are "normal" and
the balance can easily swing from one side to other, and therefore a search in
width rather than in depth should be applied in calculations. The next few

you may wonder why the name of the opening is cited as Najdorf variation
instead of Dragon at the top. The game transforms in a position which has an
opening classification B92 (Najdorf, Opocensky variation). You will be
surprised to learn that the Black bishop will never end up on g7 in this game!
However in a variation which was eventually played by Black, it is not rare
that the bishop is not fianchettoed. But formally this opening can also be
classified as Dragon because of Black's specific pawn structure, and how the
game starts. Or maybe it should be named Dragon-Najdorf?!} 6. Be3 a6 {Probably
an attempt to surprise the opponent with less theoretical and unusual setup.

could not escape the consequences of his weakened pawn structure introduced by
g6 in this particular case.} 18. Qd4 {The best "machine" move here is 18.Qc3!?,
but from "human's perspective" 18.a5 or first 18.c4 then 19.a5 deserved

{Before this game, I knew Bindi was a tough opponent, as he smashed me in the

Sicilian. Unfortunately for him, I knew theory there as well.} 1. e4 c5 2. Nf3

Diagram [#] This is a normal theoretical line in the Najdorf. The most popular
response is either Bg5, or Bc4. I decided to play a line that Karpov used to
play most regularly.} 6. Be2 {This was Karpov's calm move, with no real
intention of attacking, just attempting to get a positional edge over your
opponent. After Be2, there are two good responses for Black: ...e6 or ...e5.
...e5 usually leads to boring positions, and knowing Bindi, I wasn't afraid of
his response.} e6 7. O-O Be7 8. Be3 O-O 9. f4 Nc6 10. Kh1 {This is still
theory, and I probably still played Kh1 prematurely, but I just wanted to keep
my king safe from the a7-g1 diagonal.} Qc7 11. Qe1 Nxd4 12. Bxd4 b5 13. Bd3 Bb7
14. Qg3 {Diagram [#] My bishops are placed very well, and after Qg3, I am
ready to attack my opponent's king. The only piece defending his K is his
knight, but White has two ways of attacking the Nf6: pushing e5, or playing
Nc3-d5 as a sac to open lines for the bishops. That is a very typical idea.
For example: 15...Bc6 16. Qh3 Rac8 17.Nd5. With ideas of 17...exd5 18.exd5 and
threatening mate on h7. Also, if Black goes ...b4, the Knight goes from
c3-d1-e3-g4 and trades the Nf6. The e4 pawn isn't hanging after Nd1 because
there's a mate: 14...b4 15.Nd1 Bxe4? 16.Bxe4 Nxe4 17.Qxg7#. Knowing Bindi
though, he wasn't going to allow me to have all that, but these tactical
threats may force Black to weaken his king side position with ...g6.} Nh5 $4 {
A huge error. The only piece that was defending his king, and with one move,
Bindi puts his best piece out of play.} 15. Qh3 Nxf4 16. Rxf4 e5 {Diagram [#]

tactic that Bindi missed...} 17. Nd5 $3 {A strong in-between move forcing
Black to give up his strong bishop. If Black doesn't take the knight, (e.g. 17.
..Qd8) White goes 18...Bb6 and is up a piece, or even more.} Bxd5 18. exd5 g6 {

the better minor piece and better structure. A big problem with defending
the IQP with major pieces and only one minor piece is that if Black defends
from behind, then the Pd5 might get pinned on the d-file, and e3-e4 creates a
winning lever against it. But if Black defends the Pd5 from the side (as he's
