1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. Bf4 $5 {This move is a rarely chosen reaction
to the Queen Indian Defence. White most commonly plays 4.g3 and finishes
kingside development while its bishop is waiting on its original square or
placed on d2 to block Bb4 check. Although the text move is certainly playable,
the bishop might find itself poorly placed.} (4. g3) 4... Bb7 5. e3 Bb4+ 6.
Nfd2 {(DIAGRAM) This move looks strange at first, but it actually carries an
interesting idea. After actively developing bishop to f4, White prevents Black
from attack it with Nh5. Second idea is to chase away the Bb4 with a2-a3,
without allowing pawn destruction which usually happens when White places a
knight to c3.} O-O 7. a3 Be7 8. Nc3 {At the end, this Bf4 sideline does not
look bad at all!} c5 $6 {(DIAGRAM) This is both the first active and dubios
pawn move. Black invites White to close the center and transfer the position
into Benoni style structure while his both bishops are passively placed.
Especially the bishop on e7 would more enjoy its typical stay at g7 square.
Surprisingly there were other strong players that chose the text move so there
might be something good in disguise.} ({I feel it is better to grab the d-pawn
and actively play} 8... d5 9. cxd5 exd5 10. Bd3 c5 {leads into interesting
play.}) 9. d5 d6 ({Recapturing is not recommended. White has strong a resource
there!} 9... exd5 10. cxd5 Nxd5 11. Qf3 $1 {Pinning the bishop and causing
some trouble for the corner rook. Black can try:} Nxf4 12. Qxb7 Nc6 13. exf4 {
and although it looks risky for White, it is not possible to trap the queen.
White will consolidate soon and keep material advantage.}) 10. e4 exd5 $6 {
This does not look like a good move either. Black jumps to a bad Benoni where
his pieces are passive and where White will be able to get a powerful play in
the center.} ({One possibility can be} 10... Na6 {with the plan of Nc7 and b5
to push for space and active play.} 11. Bd3 Nc7 12. O-O b5 13. b3 Nd7 {and
Black has reasonable chances of obtaining counterplay.}) 11. cxd5 Re8 12. Be2
Ba6 {Fully understandable. Black bishop has no business on b7 and is better
off exchanged.} 13. O-O Bxe2 14. Qxe2 Bf8 15. Bg5 {(DIAGRAM) This pin looks
quite annoying plus White clears the f4 square for its pawn. White's position
is clearly more comfortable here.} Nbd7 16. f4 $1 {Massive control of the
center is established, next on the list is e4-e5.} Qb8 17. a4 g6 {This move
proves that the whole benoni plan was not good when Black spends extra time
aiming to get the bishop to the g7. Unfortunately, it is a little late to
realize that bishop belongs there. White already got a lot of time to control
important squares.} 18. Rae1 ({Computer prefers immediate} 18. Qf3 Bg7 {and}
19. Nc4 {to attack the king via f5 and the later open f-file. Hard to argue
with this plan.}) 18... Bg7 19. Qa6 $6 {(DIAGRAM) Mysterious! I am not exactly
sure what idea is behind this move. It prevents a7-a6 and b6-b5 break, but it
is unclear if this idea is a real thread. Instead of decentralizing the queen,
White should be aiming for either e4-e5 or f4-f5. Whites position is still
better as he can bring his queen back to e2 at any point.} ({Recommended would
be} 19. Qf3 {which threatens the thematic e5 or f5. Variation could continue
with} a6 20. e5 $1 dxe5 21. f5 $1 {where White has a clear edge.}) 19... Ng4

better here. It seems to be good to have the knight placed on c3 instead of d1.
}) 20... Bd4+ $1 {Finally getting the chance to be active! Black is no longer
worse here.} 21. Kh1 Bf6 $2 {Why to go back? With his king being weak, it was
not wise to exchange the kings defender.} ({Although Black's position does not
have a very active plan, he should play Qc7 and try to improve its position.}

24. Nc3 {(DIAGRAM)} Qd8 $2 {Truth to be told, it is very difficult to find a
good move for Black here. However, the queen on b8 was protecting d6 pawn and
preventing the white pawn's march in the center. It should have stayed there.}
({A better option was} 24... a6 {, but White is still better after the
well-known plan of} 25. e5 dxe5 {and} 26. f5) 25. Nc4 Nf8 26. Qd3 {The last

Black intends to develop his bishop to h6 with a tempo and speed up his
development. However, the problem is visible after the plan execution when
both the bishop on h6 and the knight on g4 is oddly placed and causes
disharmonization of pieces. Most likely is would be better to place the bishop
on g7 to counter his opponent on b2 and the knight on f6 will have option of
going to d7 and later to c5.} 11. Nf3 ({As mentioned before, I would recommend
