There was a lot of coverage of Qiyu's performance at the WYCC, but other Canadians fared well. Maïli-Jade also lead her section for some time, before losing three games in a row. Here's one of her most convincing wins against a Nimzo-Indian defense in which she carefully exploited the weaknesses in her opponent's position.

1. d4 e6 2. c4 Nf6 3. Nc3 Bb4 4. Qc2 O-O 5. Bg5 c5 6. e3 h6 7. Bh4 b6 $6 {
Until then both player followed the theory without creating any imbalance.
However, it would have been better to take advantage of the fact that the
White queen does not protect the d4 pawn anymore and open the c-file.} ({
Instead} 7... cxd4 8. exd4 Nc6 9. Nf3 d5 {And Black has completely egalized.})
8. dxc5 (8. a3 {Also interesting was} Bxc3+ 9. bxc3 {Obtaining the Bishop pair.
However, White cannot take in c5 anymore, as it would create too many
weaknesses.}) 8... bxc5 ({Taking with the b-pawn helps solidifying the center,
but Black must be ready to perhaps give up the bishop pair. Taking with the
bishop is also entirely possible :} 8... Bxc5 9. Nf3 Bb7 10. Be2) 9. Nf3 Bb7
10. Bd3 (10. O-O-O $5 {Is a move that would have attracted a lot of young
players. However, Maïli-Jade is not a big fan of such tactical positions and
probably made the best decision.}) 10... d6 11. O-O {Now Black must make a
decision. She could take either knight or play Nbd7 and all three moves can
lead to completely different positions.} Bxf3 $6 (11... Bxc3 12. Qxc3 Nbd7 13.
Nd2 Qb6 {Would have given Black a good game. Black has a strong center and
very coordinated pieces, although the d6 pawn could end up being a big
weakness.}) 12. gxf3 Bxc3 13. Qxc3 Nbd7 {As surprising as it may seem, the f3
pawn is not such a weakness in this position. White has the bishop pair and
could even launch an attack on Black's king.} 14. Rfd1 {The d6 pawn is Black's
only weakness and White has to somehow take advantage of that. Furthermore, it
is always a good idea to solidify the center before trying to attack.} Qb6 15.
Bf1 $6 (15. Bg3 {Is a simple yet efficient to add pressure on d6. Black will
have to play either e5 or d5, creating more weaknesses.}) 15... Rad8 (15... d5
16. cxd5 Nxd5 {Would have allowed Black to release the pressure in the center.
However, Black has not much compensation for the bishop pair.}) 16. Rd2 g5 $2 {
Creating more weaknesses and only helping White to attack d6 another time.} 17.
Bg3 e5 $2 {Black now fixes her own weakness in d6. This is a huge mistake, as
White will now be able to consolidate the pressure on the d-file.} 18. Rad1 $1
Ne8 {White has now a critical advantage and must find a way to convert this
into a win.} 19. f4 $1 exf4 {Black cannot afford to let White open the d-file
for its rooks.} 20. exf4 g4 {There is not much to do anymore. Black does not
want to open the g-file, but is losing a precious tempo.} 21. Bh4 f6 22. Qg3 h5
23. h3 f5 {Perhaps slightly better was Rf7, but even with a perfect play Black
cannot stop the attack.} 24. Bxd8 Qxd8 25. hxg4 fxg4 26. Rd5 Ndf6 27. Rg5+ Ng7
28. Bg2 Qe7 29. Qc3 h4 30. Re1 Qd7 31. Bd5+ ({Another elegant way to win was}
31. Re6 $1 Qd8 (31... Qxe6 32. Bd5) 32. Rg6) 31... Kh8 32. f5 Nxd5 33. cxd5
Rxf5 {As White can simply take the g4 pawn with a crushing advantage, Black
resigned.} 1-0
