Abrahamyan is a seasoned veteran of elite American chess, a member of the
United States' Women's National Team for nearly a decade. So what happens in
Iceland when a teenage superstar meets a player who just grossly
underperformed at the U.S. Women's Championship? How does Liang, with the
white pieces and the much higher rating, fare against Abrahamyan, the underdog
who beat a grandmaster earlier in the event?} 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4.
g3 Bb7 5. Bg2 Be7 6. O-O O-O 7. d5 ({Significantly more common is the natural
development of the queenside material, starting with} 7. Nc3 {whereafter the
principled reply} Ne4 {is met by the increasingly popular} 8. Bd2 {A
particularly brilliant game following this line was played by Levon Aronian,
who defeated Richard Rapport in just 28 moves at the 2017 Tata Steel
tournament.}) 7... exd5 8. Nh4 Ne4 ({Frequently seen here is} 8... c6 {with
mixed results. The essential concept is that Black goes up a pawn but has to
deal with clumsy minor pieces. For instance,} 9. cxd5 Nxd5 10. Nf5 Nc7 11. e4
d5 12. Nc3 Bf6 13. exd5 cxd5 14. Bf4 Nba6 15. Re1 Qd7 16. Bh3 {was essayed by
Garry Kasparov in a demolition win over Slavoljub Marjanovic at the 1980
Olympiad. With the advent of high-powered chess engines improvements are of
course readily apparent, but the pitfalls that Black must avoid are evidently
numerous.}) 9. cxd5 Nd6 10. e4 $5 {White's tenth move begs the question that
all chess players - amateur and grandmaster alike - struggle with: when is it
correct to sacrifice a pawn (or more) for the initiative?} ({In our mental
calculations, let's start by acknowledging that the sequence} 10. Nf3 Bf6 11.
Nc3 Na6 12. Bf4 Bxc3 13. bxc3 Nc5 14. Bxd6 cxd6 {[#] appears to be ugly for
Black, thanks to the doubled, isolated d-pawns. But upon further inspection
the situation proves to be far murkier, as the upside of doubled pawns is an
additional unimpeded file for a rook. Black quickly obtains sufficient
activity to offset the problems associated with the compromised pawn structure.
In fact, I'd even prefer to take Black here. Thus, it is no surprise that
Liang dismissed this option.}) 10... Bxh4 11. gxh4 Qxh4 {[#] Alright, it's now
time to take stock. White has the bishop pair as compensation for the
sacrificed pawn. Yet it is not any old pawn, but an extremely valuable
kingside protector. In its absence it is psychologically tougher to push e4-e5,
as the knight aims to jump into the action via f5. Unlike in sharp Sicilians,
here White relies on initiative rather than tactical motifs. In order to make
progress, White must make concessions along the way. With a significant rating
edge, Liang must have believed the imbalance would play out in his favor.
Abrahamyan, to her credit, goaded her opponent into a variation that
challenges him to prove he has enough for the pawn.} 12. Nc3 {This move is by
no means bad, but it is not forceful. Some positions require patience, but
here action was warranted.} ({The first move that comes to mind is} 12. e5 {
Liang wouild seize additional space and boot the knight from its surprisingly
strong square. A perfunctory glance at the numbers the engine spouts does
little to help humans evaluate the immense complications. The drawback of this
pawn push is that Black can more easily poke at the center:} Ne8 {13. f4 d6 is
tense. White has a number of options including 14. Qe1, as the queen swap
removes Black's most active piece.} ({Queen safety issues arise after} 12...
Nf5 13. Nc3 d6 14. Ne4 {White is happy to keep sacrificing pawns if it means
the enemy queen will be hunted.} Qe7 {(Black will not enjoy the pawn storm
after 14...h6 15. Ng3! Nxg3 16 hxg3 Qd8 17. exd6 cxd6 18. f4)} (14... h6 15.
Ng3 Nxg3 16. hxg3 Qd8 17. exd6 cxd6 18. f4) 15. Bg5 {gives away a second pawn,
and after, say Qxe5 16. Re1 Qxb2 17. Qg4, it is increasingly evident that
White's counterplay leaves Black with the uneviable task of parrying threat
after threat. White certainly stands better, though who can blame Liang for
not foreseeing all of this?} Qxe5 16. Re1 Qxb2 17. Qg4) 13. f4 d6 14. Qe1)
12... Qe7 $1 {Abrahamyan's defensive instincts are correct. She hardly wanted
to have her queen stranded on h4, a powerful square only in theory.} ({Black
would have lost a key protector of the e5 square had she begun with} 12... f6 {
Importantly, the queen lacks retreating squares, which is most clearly
evidenced by:} 13. f4 Re8 14. f5 $1 {[#] The queen has run out of breathing
room, and the sacrificial attempt Nxe4 is met by 15. d6!!} Nxe4 15. d6) 13. f4
({It is easy to acquire tunnel vision when the whole foundation of the pawn
sacrifice was to best support e4-e5. But if Liang was given this position as a
study rather a game played from move one, I am confident he would recommend} 
13. Bf4 {The bishop applies pressure along the diagonal, the rook can come to
c1, it is unclear how Black can best develop, and Bg3 followed by an eventual
f4-e5 is in the cards. White is better here.}) 13... f6 14. Re1 c6 {Abrahamyan
finds a necessary resource. Black can hardly wait for the pawn storm to occur;
rather, she chisels at the center immediately.} 15. e5 $6 ({With every move,
it feels as if the advice shifts from active to deliberate strategy. Here,
once again, White should have chosen the more patient path. Abrahamyan rightly
was worried about} 15. b3 {threatening to pin the knight. Black can't capture
on d5 anytime soon, so she is forced to coordinate another way. While 15...Na6
or Nf7 are both perfectly reasonable moves, both sides begin to feel the
tension. In the game, Black became free.} Na6) 15... fxe5 (15... Nf7) 16. fxe5
({White's pawn structure is left in shambles after} 16. Rxe5 Qf6 {though Black
will still struggle to set her pieces loose. The extra pawn looks much more
promising now than it did five moves ago, but bishops do love open space.
Black is to be preferred, but things easily can go awry.}) 16... Nf5 {[#]} 17.
e6 $6 {Another inaccuracy is all Abrahamyan needs to grab the upper hand for
good.} ({Liang likely avoided} 17. d6 {because he feared allowing his opponent
to blockade his pawns. However, this accurate pawn push was required here.
Objectively Abrahamyan's position is excellent, but without comfortable homes
for her pieces, there are many technical difficulties. These lines evidence
the complications:} Qe8 (17... Qe6 18. Ne4 {quickly becomes double-edged. Pawn
gobbling merely allows White's pieces to activate with tempi, as Qxe5 19. Bd2
with the threat of Bc3 and Qg4 is promising.} Qxe5 19. Bd2) 18. Qg4 Na6 19. b4

{During the last round of Supernationals VI, I finally reached the DGT boards.
After six exhausting rounds of chess, everything was up for grabs. There were
three people tied for first going into the final round, but with the tight
competition, a massive tie for first was certainly possible} 1. d4 Nf6 2. c4 c5
3. d5 b5 4. cxb5 a6 5. bxa6 g6 6. Nc3 Bxa6 7. e4 Bxf1 8. Kxf1 d6 9. Nge2 Bg7
10. h3 Na6 11. Kg1 O-O 12. Kh2 e6 13. Ng3 Nc7 14. Bg5 exd5 15. exd5 Qd7 16. Qd2
{[#] In the Benko Gambit variation that I play, normally black develops his
pieces aimed towards a queenside attack, rather than breaking open the e-file.
Therefore, when I reached this position, I had to develop a new plan - ideally,
I could double my rooks quickly on the e-file and plant one on e7, but
black’s rook penetrated to the fourth rank too quickly. I had to settle for
attempting to protect my d5 pawn.} Rfb8 17. Rad1 Rb4 {At this point, Rd4 is
the key move. Playing Qc2 allows Nb5, and the queenside is too weak to
maintain. Trading off the bishop for the knight doesn’t help because the
resulting activity from black’s bishop is possibly more devastating. Instead,
I headed into complications.} 18. Rhe1 (18. Qc2 Nb5) 18... Rd4 19. Qe2 Nfxd5
20. Rxd4 (20. Nxd5 Nxd5 21. Rxd4 Bxd4 22. Qf3 Qc6 {I was less fond of this
move order because I felt that by keeping more pieces on the board, I allowed
myself more chances to attack and/or restrict the movement of the d5 knight.})
20... Bxd4 21. Qf3 {[#] The pin on the knight, and the lack of viable squares
makes black’s position difficult. The constant threat of Re7 forces either
the trade or Qc6. Placing the queen in the pin seems extremely
counterintuitive, and I was planning to meet it with Nge4 followed by Bf6.}
Bxc3 22. bxc3 Ra3 23. Ne4 {Without a bishop, black’s dark squares are
extremely weak. The centralized knight on e4 effectively targets both d6 and
f6, as well as protects the weak c3 pawn. While material might be equal and
black’s pawn structure is more solid, my better coordinated attacking pieces
give me the practical advantage.} Ne6 24. Bc1 {[#] No effective discoveries
exist, and the bishop is much too useful to trade. By retreating, the attack
on the a3 rook forces it to move, and frees the c3 pawn to threaten the knight.
The weakness of the f6 square allows white a variety of tricks and a back rank
attack is always in the works.} Rxa2 25. c4 Nd4 26. Qg3 (26. Qf6 Nxf6 27. Nxf6+
Kg7 28. Nxd7 Rxf2 29. Rd1 Re2 {The cute Qf6 was tempting, but I felt that the
piece-up endgame resulting from the trade of queens was more complicated than
it seemed, at least during the game. I preferred keeping the queens on the
board and attacking in the middle game, in order to maintain as many chances
as I could in this crucial round.} 30. Bf4 Re7) 26... f5 27. Nxd6 Nc7 28. Be3 {
Here, I felt there had to be a crushing blow to advance the attack, but to my
surprise I couldn’t find anything. Black’s knights coordinated to stop the
onslaught, and my pieces weren’t yet ready to finish off the advantage. This
simple move with the idea of trading for the knight and forming an outpost on
d6, also opened up the route to the b-file for my rook} Nc2 29. Rb1 Nxe3 {[#]}
30. Rb8+ {The intermediate check finally allows penetration into black’s
position. Now the attack with three pieces breaks through, and the
coordination between the queen and the knight is showcased. Black’s rook is
out of place; it should be back on the back rank defending the king. Playing
Ra8 or Ra6 instead of Nc4 would have allowed black better defensive chances,
but white is still objectively better.} Kg7 31. Qe5+ Kh6 32. Qxe3+ Kg7 33. Qe5+
Kh6 34. Qf6 {Once again, there is no series of forcing moves to push the
advantage through. The king can always shuffle between h6 and g7, and the
black queen and knight defend any knight moves for now. Instead, a quiet queen
move with various threats essentially seals the deal.} Kh5 {[#]} 35. Rh8 {
At this point, most moves win, but I chose the slower Rh8 to avoid any
unnecessary blunders. 35. Nxf5 looks tempting, followed by either g4+ or Rg8,
but a variety of other options would lead to mate as well.} (35. Nxf5) 35...
Rxf2 36. Kg3 {Now white’s king joins in on the attack as well! By
threatening Qh4 and removing itself from the pin on the g-pawn, my king goes
on its own run to finish the game. My calculation was not functioning the best
at this point, so I missed some quicker wins, but it worked out in the end.}
Rf4 37. Kxf4 Ne6+ 38. Qxe6 Qg7 39. g4+ Kh6 40. Nxf5# {A cute queen sacrifice
finally ended the game. The middle game positions started out around equal,
but by playing into some complications, I was able to confuse my opponent with
different move orders. Trading off black’s dark squared bishop for my knight
allowed me control of the crucial dark squares around black’s king, and
helped me mount a strong attack. A couple of inaccuracies from my opponent
assisted in finally penetrating, and after that, the coordination between my
queen, knight, and king (!) took care of the rest.} 1-0

important win of my tournament. This win would mean a draw with black would
very likely be good enough to tie for first, and I was able to hold against
Kesav.} 1-0
