Ruifeng Li Wins Philadelphia Open

ruifenglilukeharmon Ruifeng Li, here pictured against Luke Harmon at the US Chess School
IM Ruifeng Li scored an undefeated 7-2 at the 10th Annual Philadelphia Open tying for first and winning the $200 first place tiebreak bonus for a total of $5415.  Li tied with GM Aleksandar Indjic who he defeated in round 5.  Indjic scored 3 ½ out of his last 4 games to catch Li who “coasted in” with four draws.  Even though Li made four draws in the last four rounds, many of them were fighting draws and Li had opportunities to win.  His games were 42, 45, 32 moves and it was only in the last round that he played a 15 move draw. Here is Li’s game against his co-champion, GM Aleksandar Indjic:

Li played four GMs in this tournament scoring two wins and two draws.  In doing so, preliminary calculations are that he crossed 2500 FIDE for the first time and made his first GM norm.  Once he achieves his 2nd and 3rd norms, he will receive the title. Li is only fourteen years old and he is currently the highest rated 14 year old in the USA.  He is also ranked number 7 in the world for Under age 16.  He has been rapidly improving having gained nearly 100 points in the last year and recently crossing 2600 USCF.  Li received the IM title last year and appears on the verge of earning the GM title.  Ruifeng played the majority of his games on board one.  He liked the DGT and Monroi broadcasts and the quality provided to the top players.  One of the interesting things about GM norms in Swisses is that the math changes every round.  Li had already played the necessary four foreign players going into the last round.  Had Li been paired up in the last round, he could have lost and still made the GM norm.  Because he was paired down to FM Craig Hilby who was also having a breakout tournament performance, the average rating of his opponents dropped slightly and he needed a draw.  I suspect that was part of the motivation (along with $5000) to make a quick draw in the last round!  Ruifeng often comes to tournaments with his younger sister Rachael and they form a mixed doubles team.  Sometimes she scores more points in her class section than he does!  This time he had a different mixed doubles partner and didn’t win any mixed doubles prize.  Still, I think the $5000 and GM norm made up for it! GM Aleksandar Indjic also tied for first.  Indjic played fighting chess through the tournaments and his six wins were the most victories of anybody in the tournament.  Indjic lost only to Li and he drew Hilby and GM Sam Sevian,.  Indjic defeated GM Ioan Chirila and IMs Farai Mandizha, and Michael Mulyar.  Here is Indjic’s win over GM Chirila.

Craig Hilby tied for third with 6 1/2 points.  He made an IM norm with a round to spare!  This is his second IM norm as he made an IM norm last year at the World Open.  As noted, he drew both of the champions.  He also drew GMs Alexander Fishbein and Sandro Pozo Vera.  His significant wins were back to back wins over IMs Awonder Liang and Zurab Javakhadze in rounds seven and eight.  Here he annotates his round 8 win over Javakhadze.

{I had come in before the game needing 0.5/2 in the last day for an IM norm.
However, 2/2 could get me a GM norm and first in the tournament. I couldn't
make up my mind whether to be satisfied with a draw or to go all out for a win,
so I just decided to try and play the best moves :)} 1. Nf3 Nf6 2. g3 g6 3. b3
{I had actually expected this from him, as he had games in the database with
this strange move before. The idea of course is that if White wants to
fianchetto this bishop, he should do it before Black's bishop gets to g7.
White is playing for a space advantage.} (3. Bg2 {would have actually more or
less taken me out of theory becayse I have never played 2...g6 or King's
Indian before}) 3... Bg7 4. Bb2 O-O 5. Bg2 {I spent most of my time here in my
preparation trying to figure out how Black should proceed, and I (actually,
more like Stockfish) came up with an idea that had not been played very often
at all.} c5 {Natural, putting some grasp over d4. As a Benoni player, I always
like having the pawn on c5.} (5... d6 {was the other main move I had
looked at, with the idea being} 6. d4 e5 (6... c5 {was also interesting, but I
decided I liked what I played better.}) 7. dxe5 Nfd7 8. O-O dxe5 {but I wasn't
really too comfortable with the position after} 9. e4) (5... d5 {and other
moves are also of course, playable.}) 6. c4 {White's LSB on g2 is stronger
than mine on c8. The idea is that if I go d5, White will get to trade DSB's,
and we will get a position with a couple knights and a superior LSB for white.
White will try to use the c- and d-files to infiltrate into the Black position.

a pawn! This is a very rare move but one that I liked while preparing.} (6...

game} (7... d6 {is the main line, which goes} 8. d4 cxd4 9. Nxd4 Bd7 10. Nc3 {
This position did not really appeal to me})) 7... d5 {should equalize pretty
easily}) (6... d5 {The immediate break does not quite equalize} 7. cxd5 Nxd5 8.

will not be complete liquidification in the center, as I will always take back
on d5 with the pawn.} 10. Nxc6 {A surprise for me, I hadn't looked at this
before the game. I had only looked at positions where I had the isolani on d5.}
(10. cxd5 {giving me an isolani was definitely the most natural.} exd5 {
However, White does not have any real pressure on the d5 pawn, and meanwhile
Black can play Re8 and Bg4 and create his own counterplay very easily. I do
not think Black is worse here.}) (10. Nd2 {I also considered, but that thought
I would be fine after} Re8 11. Rc1 Nxd4 12. Bxd4 e5 13. Bb2 d4) 10... bxc6 11.
Qc2 {Okay, so White's idea is clear. I cannot move my c- or e-pawns forward
without creating serious weaknesses, and meanwhile White will try to control
the dark squares (d4, e5, c5). Meanwhile, Black has to find some way to create
counterplay.} a5 $2 {I wanted my bishop on a6, and was trying to decide
whether or not to include this move. It didn't feel right having my bishop
just unprotected on a6, so I decided that a5 couldn't be that bad. However,
this is probably too slow.} (11... Re8 {was also interesting, trying to play
e5.} 12. Nc3 Rb8 (12... e5 13. cxd5 cxd5 14. Rfd1 Bb7 15. Nxd5 Nxd5 16. Bxd5

see what I had accomplished here though}) (11... Ba6 {Maybe I was just scared
of ghosts, and the bishop being unprotected on a6 did not actually mean
anything. After} 12. Rd1 Rc8 13. Nc3 Qa5 $1 {An advantage of not playing a5;
The queen can now access that square.} 14. Na4 dxc4 15. bxc4 Ng4 {Black should
be fine}) 12. Nc3 Qe7 13. Rfd1 (13. e4 d4 14. Na4 e5 {is definitely okay for
Black}) 13... Ba6 14. Na4 Rfd8 15. e3 $6 {Allowing me to relieve some of the
pressure.} (15. Bc3 $1 {is what I was somewhat afraid of, but I figured that}

losing.}) 16. Bxa5 (16. Rac1 $1 {However, keeps the advantage} dxc4 17. Rxd8+

(putting more pressure on c4) to the list of possibilities.} 16. Bxg7 Kxg7 17.

is better according to Stockfish. The queen is annoying, putting
pressure on the White queenside, and can't be kicked out easily.}) 18. cxd5

dxc4, Bxc6 hitting my rook will be annoying. In addition, the rook might be
nice on b4 to attack White's queenside. Also, the concrete point is shown
after White's next move.} (17... dxc4 {I actually thought for about half an
hour on this move, trying to decide if this worked.} 18. Bxc6 $6 (18. Qc3+ $1 {

Good report by Dave, and another comprehensive annotation by young Craig Hilby, who won a Chess Journalists award for one of his thorough dissections two years ago. He swears he does this for all his games, not just those that are published! (I assume that in the note to White's 20th, "22.c5 $11" is a typo that will be corrected.)
