{At the beginning of the year, I have received the news that my mother wasn't
well, but by the time I arrived back home to Romania things got even worse and
I learned that not much could be done, and on the 21st of January we lost my
mom. The news has come as a shock knowing how much she would have wanted us to
play together in the Women's World Chess Championship, and of course further
to see me finally perform well in the US Women's Championship. Finishing in
top 3 in one's National Championship is a dream come true to every player, but
for me this year would have been even more special. I started the tournament
with a dissatisfying 2/4, with two wins and two losses. I was 6th seed in the
tournament and nobody expected anything better of me, but I did. I was able to
put myself together and gain momentum so that after the 10th round, I was
sharing the 1st place with former US Women's Champion Nazi Paikidze, both with
7/10. The last round I had to give it my all. Playing with the black pieces
against the talented Apurva Virkud, wasn't going to be easy, but I had to give
it my best shot. I opted for the Nimzovich, a surprise opening to get us
started on a neutral territory where none of us had much preparation, or so I
thought} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 {my choice of opening didn't seem to
come as a surprise to my opponent who started blitzing her way through the
first moves.} 4. Qc2 O-O 5. Nf3 c5 6. dxc5 Na6 {I have played this line myself
as white, so I was envisioning my opponent would continue 7. g3 or 7. a3 to
either finish the development or gain the pair of bishops. However, I was
surprised by} 7. c6 {I had seen the idea previously in some other Nimzovich
lines, but not in this particular position. Following the game I learned that
Morozevich was the one who first opted for this move. The idea is to try to
delay black's knight from coming to c5. However, it helps black strengthen the
center.} (7. g3) (7. a3) 7... bxc6 8. g3 $6 ({I think} 8. a3 {was necessary
forcing black to make a decision on keeping or giving the bishop away. After}
Bxc3+ 9. Qxc3 d5 10. e3 {the position is balanced}) 8... d5 9. Bd2 $6 {Another
move which slows white's development and also doesn't try to stop black from
gaining space advantage.} (9. a3 {was once again a must; followed by} Bxc3+ 10.
Qxc3 Nc5 11. Bg2 {with a balanced position}) 9... d4 {I started feeling
confident in my position from here. My opponent has given me a comfortable
position and will have to struggle finding a way to break through my center.}
10. Ne4 {considering that white would like to trade pieces (due to the lack of
space), and that I cannot stop the trades if I want to maintain good activity
for my pieces, I have decided to finish my development and always be sure that
the way in which pieces would be traded would be in my favor.} Rb8 11. Nxf6+
Qxf6 12. Bg2 e5 13. O-O Bf5 14. Qc1 {now white might try to play 15. Bg5
followed by 16. a3 and try to gain space on the queen side, so I thought this
was the right moment to trade the bishop to stop white from any active play.}
Bxd2 15. Qxd2 (15. Nxd2 {was a better choice to slow down e4 for a little while
}) 15... h6 16. Qa5 c5 17. b3 ({White could have gone for a more active
approach by playing} 17. Nxe5 {but the following line is giving black a big
advantage} Qxe5 18. Qxa6 Rxb2 19. Qxa7 Rxe2 {and black has the control over
both opened files and will have it easy to attack white's weakness on c4})
17... e4 18. Nd2 Rfe8 19. Rad1 Rb6 $5 {The position is in black's favor, and
now I felt confident that I had to find a way to utilize the badly placed
queen in a5. The idea of the text move is Qe7 to protect my two weaknesses c5
and a7 and get ready to improve the position of Na6 which seems to have been
way overdue.} 20. Nb1 Qe7 21. e3 Bg4 22. Rd2 {[#] This is a critical moment in
understanding what should be done for the final improvement of the position}
Nb4 $1 {improving the position of the last piece which was outside of the game.
This move has helped the final ending of the game as well! I was looking
forward to} 23. exd4 {which was part of white's plan to activate her pieces.
Although until now it didn't seem like black could have any attack on the king
side and only look at how to trap the Qa5, things have changed here after} e3
$1 {white is forced to open up her king} 24. fxe3 Qxe3+ 25. Kh1 Rf6 $3 {
without this move black cannot claim a king side attack} 26. Rg1 $4 {[#] My
heart started beating really fast here. I was hoping for this move to have a
spectacular finish. I took my time to double-check that I am not hallucinating
and that I am in fact winning} Qxg1+ $3 {and the mate is unstoppable} 27. Kxg1
Re1+ 28. Bf1 Rfxf1+ 29. Kg2 Rg1+ 30. Kf2 Ref1+ 31. Ke3 Rf3+ {In this position
my opponent resigned as the mate is inevitable as follows. This remains a
memorable game for me especially for being able to find the best two moves
that started and finished the attack on my opponent's king! A wonderful way to
finish the championship in my Mother's memory!} (31... Rf3+ 32. Ke2 (32. Ke4
