{The world champion's return to open tournaments indeed had a rough start, but
by round 5 he certainly had found his pace, and on Christmas Eve he created
excellent entertainment for all those kids waiting for the evening to come.
And for all other chess-lovers:} 1. d4 Nf6 2. c4 g6 3. f3 $5 {A move that has
been very much in the limelight over the last couple of years, but somehow the
interest seems to have faded a bit, for no apparent reason except fashion.} d5
4. cxd5 Nxd5 5. e4 Nb6 6. Nc3 Bg7 7. Be3 O-O 8. Qd2 Nc6 9. O-O-O f5 (9... Qd6 {
has been established as the main line, and is what Caruana played against
Magnus in Norway Chess 2014. But Li, stays true to his favourite choice.}) 10.
e5 Nb4 11. Nh3 Qe8 $5 {Here however Li springs his surprise, just before
Magnus would had a chance to show how he thought to proceed after Li's usual
move 11..a5. The text move has the queen not only the keeping an eye on the
f7-square, attacking a2, but also ideas like ...Na4 exchanging of an important
defender of both the queenside and the d5-square. Magnus, almost in Grischuk
like fashion, here had a very long think, trying to grasp the subleties of
Li's novelty.} 12. Kb1 a5 {Black switches back to this move, the point of 12.
Kb1 being that 12...Qf7 could now just be answered by 13.Ng5! and 13...Nxa2 no
longer is check.  In a way this position is a "mini zugzwang", in the sense
that White would love to play Nf4 and h4 with a complete grip, but Black's
concept with ...Qe8 is, that Nf4 can be answered strongly by ...g5! as h5 is
protected. Thus Black do not want to play ...Be6, as this exactly allows Nf4
and h4, so both players try to bide their time, while making small
improvements to their position.} 13. Be2 c6 14. Rc1 Kh8 $6 {A logical move,
seen often in the Leningrad Dutch freeing the g8-square for the black bishop,
but with hindsight it is easy to see that the king is very vulnerable in the
h-file.} (14... Be6 {seems preferable straight away, even if} 15. Ng5 $5 {
still seems to give White a promising position.}) 15. Ka1 $1 {One could make
the same argument here in reverse, that the white king is vulnerable due to
the attack in the a-file, but there is a major difference. Partly in that
there is no white pawn on b3, and thus the direct ...a4 is harmless, but
especially as it becomes relevant in the game that ...Bxa2 is no longer check.}
Be6 16. Nf4 ({Without the inclusion of ...Kh8 Ka1} 16. Ng5 {was the move, here
however it leads to} Nc4 $1 {as} 17. Qe1 $4 {now fails to} Nxe3 {when} 18. Nxe6

down somewhat.} {Probably} 18. Nh3 $5 {is the correct way forward, preparing
19.h5, and if} ({, and} 18. Nxe6 Qxe6 19. f4 (19. h5 g5) 19... h5 $1 {leaves
the position too blocked for White's liking.}) ({The straightforward} 18. h5 g5
19. Ng6+ Kg8 {leads nowhere}) 18... h5 {by Black, then} ({and if} 18... Bxe5 {
then} 19. Ng5 $1 {followed by 20.h5 gives a very dangerous attack for the
sacrificed pawn.}) 19. g4 $1) 18. h5 Kg8 {Of course it can be seen as
admitting that move 14 was wrong, but Black will claim he won the a2-pawn, and
that White has to play energetically to prove Black's plan wrong:} 19. hxg6
hxg6 20. g4 Bb3 $1 {Neccesary,} ({as} 20... a4 {is answered by the simple} 21.
gxf5 a3 22. b3 $1 {when Black's attack comes much too late, despite winning
the white queenside pawns. But now however should the black pawn reach a3, his
threats are deadly, so Magnus has to act decisively.}) 21. Bd1 $1 {White wants
to get his queen to h2 as soon as possible, creating mating threats against
the black king, but in this way he maximises the pressure on Black's position,
exploiting the fact that the bishop on b3 is vulnerable, which is more than
Black's position can bear. Another move actually has a lot of logic too:} ({
As White wants to get his queen to h2, and also slow down Black's attack,} 21.
Ba6 $5 {comes to mind, and indeed the computers after some time shows White is
completely winning!}) 21... a4 22. Qh2 Rfd8 23. Qh7+ Kf8 24. d5 {A good move,

very accurate, the point is that after} gxf5 (24... a3 {also does not work, as}

danger is illustrated by} 28. bxa3 $4 Rxa3+ 29. Kb1 Bc2+ $3 {which forces mate.

history of Chess Olympiads. Many of my foreign chess friends opined that the
pairing and tiebreak system was unfair and by sheer luck, India made a medal
without meeting many strong teams in the top ten (except Armenia). I can only
say that the medals are simply the representation of the human effort made.
The Indian team made their effort wholeheartedly and the existing system
rewarded us with the bronze medals. If other teams felt that the pairing/
tiebreak system was unfair, I think it is only fair to have discussed this
issue in the captains' meeting before the start of the 41st Olympiad and not
after the 19th seeds finished on the podium.  However with so many people
mentioning about the unfair system in the Olympiad, I was wondering what would
be the best tie break system? Perhaps to award the medals to the teams with
the highest average of the best four rating performances of each team. Only
time will tell!} 0-1

{This is the first individual victory (national and international) I had since
Bad Homburg, Germany. God knows how happy I was. Really can't imagine how I
made it through these 4 years and 3 months time. I am really thankful for
those coaches and friends who have always been there supporting me. Hopefully
this Grand Prix is a brand new start to my chess career and I will still keep
fighting! Now let me introduce two of my games played this time.} 1. d4 Nf6 2.

Kate had been trying to play actively and gain the initiative.} (15... Ba6 {
