{What should White play after the sealed} 41... Rf8 {? One idea would be to
play passively and construct a fortress, a logical plan given the presence of

opposite-color bishops favor the attacker - was more applicable here. Active
play with the rook was necessary. But how?} 42. Ke1 $6 {seemed a likely choice,

{After 7 rounds I was in a 3-way tie with 5.5/7. In round 8 I was paired with
an internationally famed young Indian player named Aravindh. This was our
first match with each other, but the first time I saw him was in the 2011
World Youth where he was the top seed in my section U-12. This was also the
round before the rest day. I was glad I got the opportunity to play an
exciting game with a lot of risk taking from both sides. I had played a lot of
this kind of fighting chess when I was young, at the encouragement of my first
GM coach Annakov.} 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 dxc6 (4... bxc6 {Is

{This is one of the crucial games of the last round: four players were sharing
first with 6 out of 8: GM Gata Kamsky, yours truly, GM Conrad Holt, and 'the
hero' of the event IM Keaton Kiewra. While an ultimate battle was undertaken
on board 1 between Kamsky and Holt, I and Keaton were trying our chances
against GM Denes Boros and young IM-elect Joshua Sheng, respectively. Keaton,
seemingly a bit disappointed by the fact that even a victory would not have
given him the deserved GM-norm played too unambitous in the opening and
offered a draw soon, which Sheng ultimately accepted. Soon, after the opening
phase, I realized that the game between Holt and Kamsky is a close encounter
with high tendency toward a draw. Therefore, the 'postman' was up for the task
against his ex-roommate Denes Boros, who was tallying the leaders half a point
shy.} 1. d4 Nf6 2. Nf3 e6 3. c4 d5 4. g3 Bb4+ {It is almost impossible to
guess Denes opening. His opening repertoire is broader than any GM I can think
of!} 5. Bd2 Be7 6. Bg2 c6 {This continuation is referred to as 'closed Catalan

of Carlsen's games which he won as black. Although I had some vague recall
that his position was not that great, I decided to play off the book in order
to force Denes to think a bit. I indeed managed to get off the usual
theoretical lines, nevertheless, Denes kept 'blitizing' his moves like if he
had seen this position hundreds of times before.} (11. Be3 Nd6 12. b3 Nf5 13.

pawn structure and collects a number of pawns at a cost of a knight. This
knight sacrifice does not change the evaluation of the position, but it

1. d4 {Notes by Alekhine} Nf6 2. c4 e6 3. Nf3 Bb4+ 4. Nbd2 {The usual move
nowadays is 4 Bd2, in order to develop the knight on the more natural square
c3. But, on the other hand, if Black wants to avoid the exchange of his king's
bishop, he will now be forced to lose time by retreating it to e7. The text
move therefore cannot be condemned. It has the advantage anyhow of leading to
more complicated lines than the usual move.} b6 5. g3 Bb7 6. Bg2 O-O {Diagram 
[#]} 7. O-O Bxd2 {? Instead of this exchange, which yiels White the advantage
of the pair of bishops without necessity, Black could play either d5 
(Rubinstein-Alekhine, Semmering, 1926) or even Be7, followed by d6, Nbd7, etc.
In both cases he would have better equalising prospects than in the actual
game.} (7... d5) 8. Qxd2 {The correct recapture, as the queen bishoop is
wanted on the long diagonal.} (8. Bxd2) 8... d6 9. b3 Nbd7 10. Bb2 Rb8 {Black
shows his hand decidedly to early. The obvious object of the text move is to
play Ne4 followed by f5, for which purpose the bishop must be protected, to
avoid the possible answer Ng5. But the same idea could have been combined with
a mobilisation by 10...Qe7, 11...Rad8, and eventually Ba8.} 11. Rad1 {! An
interesting and effective method of meeting Black's plan. The White queen
bishop is to play in the following development a most important and
practically decisive part.} Ne4 {If Qe7 then 12 Qe3 (Ne4 13 d5).} 12. Qe3 f5
13. d5 {This pawn will only apparently be weak, as White can always protect it
by counter-attack.} exd5 {e5 instead would lose a pawn by 14 Nh4!} (13... e5
14. Nh4) 14. cxd5 Ndf6 15. Nh4 Qd7 {If Nxd5 then 16 Rxd5 Bxd5 17 Qd4 winning a
piece.} (15... Nxd5 16. Rxd5 Bxd5 17. Qd4) 16. Bh3 {Again preventing Nxd5 ,
this time because of 17 Qxe4.} g6 (16... Nxd5 17. Qxe4) 17. f3 Nc5 18. Qg5 {
Threatening not only 19 Bxf6 but also 19 B or Nxf5; and if 18...Nxd5 then 19
Nxg6 wins. Black's reply is therefore forced.} Qg7 19. b4 Ncd7 {Equally
hopeless would be Na4 20 Ba1, etc.} (19... Na4 20. Ba1) 20. e4 {! The initial
move of the decisive sacrificial combination.} Nxe4 {Black clearly based his
last hopes on this ingenious stroke. If now 21 Bxg7 Nxg5 22 Bxf8 then Nxf3+ 23
Kg2 Rxf8 24 Kxf3 Nf6 followed by Nxd5 with good fighting chances.} (20... fxe4
21. Bxd7) 21. Qc1 {! Much more effective than 21 fxe4 Qxb2 22 exf5 Qf6
yielding White only a possible win after a laborious end-game.} Nef6 22. Bxf5 {
! The surprising sequal to 20 e4. After gxf5 23 Nxf5 Black would either lose
his queen or be mated (23...Qh8 24 Nh6+ Kg7 25 Qg5 mate).} Kh8 (22... gxf5 23.
Nxf5 Qh8 24. Nh6+ Kg7 25. Qg5#) 23. Be6 {At last the d-pawn is definitely safe.
} Ba6 24. Rfe1 Ne5 25. f4 {Far the simplest way to force resignation.} Nd3 26.
Rxd3 Bxd3 27. g4 {There is no remedy against g5. This game won the special
prize for the most brilliant king side attack at Nottingham.} Qh6 28. Ng2 1-0

{Diagram [#] In July 2016 I fought very hard to win the US Junior Championship
held in the famed Saint Louis Chess Club and also earned the previliege to
represent USA in the World Junior Chess Championship. So in August, I traveled
to Bhubaneswar, India to play in the 2016 World Junior Chess Championship
tournament. I have always liked playing in international junior tournaments
since I get the opportunity to travel to countries that I have never been to,
and meet and make friends with young players from other continents, and get to
know their culture, their sports, and the fun things they do on a daily basis.
My fellow young players are all very talented, regardless of their rating.
They are rarely afraid of taking risk and playing interesting ideas, which
would make the tournament very exciting. This was perhaps the most important
game of the tournament. I was playing well so far and was on 7.5/9. My
opponent from Poland has played very strong so far, possessing a sole second
position with an undefeated record of 7.0/9. I felt very lucky to be granted
the White pieces which meant I could control the game in general. I had
succeeded in doing so and had on my hands an endgame where I was the only one
with serious winning chances. A win would really distance myself from the
field and but I would need to make high quality moves to get there, since my
opponent has demonstrated his capability to beat strong GM players in this
tournament.} 1. Nb2 $1 {My best move (part one). The main idea behind this
move is to give the c4 square to the King and later playing Nd3 to gobble up
the pawn. It also prevents Black's idea of Nc5+-a4.} (1. Nb6 {I was about to
play this move pretty quickly as I saw that in a few moves I will win the pawn
on b4.} Nxb6 2. Bxb6 Ke6 3. Kc4 Be7 4. Ba5 Bd6 5. Bxb4 Bc7 $11 {Unfortunately
what I soon realized was that even if I win this pawn the following Bishop
endgame is a fortress. White simply has no plan to win. If White tries the
break f3-f4 Black may simple recapture and play h6-h5. Invading with the King
also isn't going to work. Black will always have a method to cut off the
King's invasion, namely with the Bishop on d8-h4 diagonal and White can't go
through d8.}) (1. Na5 Nc5+ 2. Kc4 Na4 {Complicates White's task as Black's
knight starts to be annoying.}) 1... Bc5 {The only serious reply.} (1... Nc5+
2. Kc4) (1... Nb8 2. Kc4 Nc6 3. Kb5 Nd8 4. Nd3) (1... Ke6 2. Kc4) 2. Nd1 $1 {
The big point. My knight supports the Bishop on e3 and my next move is Kc4. If
not for this move Black would have no problems whatsoever.} (2. Bxh6 g5 3. h4
gxh4 4. gxh4 Kg6 5. Bg5 Bd4 {Leads to a complete draw.}) 2... Bxe3 (2... g5 3.
Kc4 Bf8 {Retreating would simply delay the inevitable.} 4. Nf2 {There is
nothing Black can do to save the b4 pawn against Nf2-d3.}) 3. Nxe3 $16 {
Diagram [#] This idea won me the b4 pawn without issues and I eventually
managed to win. In doing so I extended my tournament lead to a full point.
This has put me in a very comfortable position in the competition for the gold
medal. I only needed to play solid chess in the rest 3 games to maintain my
lead. I was able to do just that and brought the gold medal back to USA, after
last time GM Tal Shaked won it in 1997.} 1-0
