1. d4 ({It is interesting to compare the variation played in this game with a
modern English anti-Nimzo setup:} 1. Nf3 Nf6 2. c4 e6 3. Nc3 Bb4 4. g4 $5 {
In this variation Black has less control in the centre and White has not spent
a tempo on committing his queen, so intuitively I would say that Black's
chances of finding a clear-cut antidote are slimmer. But at the same time
hundreds of games have been played starting from this position and there is no
better theoretician than the accumulation of practice!}) 1... Nf6 2. c4 e6 3.
Nc3 Bb4 4. Qc2 Nc6 5. Nf3 d6 {This is one of my favourite ways of meeting 4.
Qc2. Black avoids the theoretical lines by setting up a strategic battle where
understanding plans and structures is more important than memorising
lines-lines-lines. White's main continuations are 6.a3 and 6.Bd2, but after
the previous round win with Black Mamedyarov was in an aggressive mood.} 6. g4
$5 {"Almost" a novelty. The early advance of the g-pawn has become a common
pattern in many openings. Imagine, they have tried it in the good old
Tartakower Queen-s Gambit! But every time it pops up in a new form, the
surprise effect may be at least as big as when Bogoljubov faced Keres' 6.g4 in
the Scheveningen Sicilian, back in 1943. Since Black has relatively good
control in the centre in our Nimzo-Indian position, this attack should not be
too dangerous, but meeting it over the board may be unpleasant without
previous (at least brief) preparation. "Did my opponent analyse this
thoroughly or is it just an experiment?" Or: "Could he have meant 6.g3, but
dropped the pawn one square too far?" And finally, after failing to answer
those above: "Should I have played the Queen's Gambit Accepted?!" These are
the kind of questions that may be assaulting the player with Black while his
team-mates would think he is emerged in deep calculation. Or at least this
would happen with me, maybe other players have better over-the-board
discipline.} e5 {Ivan replied relatively fast, after eight minutes. After all,
...e6-e5 is the main idea of the whole variation. However, there are many
reasonable alternatives.} ({If taken by surprise, I would probably play} 6...
