Here is another game from the recent Hart House Holiday tournament. Black played a pretty accurate game and showed how patience can be extremely important in some positions.

1. d4 d6 2. Nf3 ({Black must be prepared to play the French, as White can play
} 2. e4 {Although many d4 players will prefer not to enter such lines.}) 2...
Nf6 {So far, Black has many options. It can play a King's Indian setup with
g6-Bg7, or play for a c5 or e5 push, or even plans involving c6-b5 in some
cases!} 3. c4 Nbd7 {Avoiding the King's Indian main lines, but White should
still know the lines with Nbd7, as they are pretty common as well. This
variation is usually called the Old Indian Defense, as Black often plays Be7
instead of Bg7 (although a fianchetto is still possible).} 4. g3 (4. Nc3 e5 5.
e4 {Leads to the main line of the Old Indian Defense.}) 4... c5 $5 {It is not
a bad move, but it is also not the most obvious one either. Black may have
wanted to surprise White.} (4... e5 {Still seems somewhat more logical, as
Black may want to move Be7 and castle rapidly.}) 5. Bg2 g6 6. O-O Bg7 7. Nc3
O-O {This setup could be familiar for Benoni players, and has some chance to
transpose in a Maroczy bind, although White probably doesn't want to play e4,
as it would restrict its bishop diagonal.} 8. b3 {This move may seem odd at
first to some, but it is actually very common. It allows White to protect c4,
which often becomes a target, and also frees the b2 square for the bishop.} (8.
d5 {Leads to a very interesting position, but White may not be used to Benonis
and should thus be careful before venturing into those complicated lines.} {A
typical continuation would be} a6 9. a4 Rb8 10. e4) 8... Rb8 9. Bb2 Qa5 $6 {
Probably the first dubious move of the game. Black doesn't lose anything, but
it's really not clear what the queen is doing there.} (9... a6 10. a4 cxd4 11.
Nxd4 Nc5 {And Black has a decent game, although White keeps a small edge, as
it is usually the case in these positions.}) 10. e3 a6 11. a4 {White wants to
prevent a b5 push, as this would significantly help Black.} Qc7 {Well, the
queen wasn't doing much in a5, so it's time to bring it back.} 12. h3 b6 13.
Re1 Bb7 14. e4 (14. d5 $5 {Is promising for White. It severely restricts
Black's b7 bishop, and it's not clear how Black would continue, besides maybe
trying to exchange pieces to have more space.}) 14... Rfd8 (14... cxd4 15. Nxd4
Rfc8 {And Black has a solid position}) 15. Qe2 {Again, d5 was probably best.}
cxd4 16. Nxd4 e6 17. Rad1 Rbc8 18. f4 $6 {This is a pretty risky move. White
has definitely some attacking potential, if Black is not careful, but if the
center opens, White could be in trouble.} Nc5 19. Qc2 Qb8 20. b4 (20. f5 $2
exf5 21. exf5 d5 $1 {And Black is much better}) 20... Ncd7 21. Qe2 Nh5 $1 {
Putting pressure on g3, preventing g4 by attacking f4 and freeing the g7
bishop.} 22. Qd3 $2 {Not only does it do a poor job at protecting g3, but it
fails to some later tactics. White probably wanted to add pressure on d6, but
it is simply not working.} (22. Kh2 {Was best}) 22... Qc7 (22... Ne5 $1 23.
fxe5 dxe5 {And Black is winning}) 23. Bf1 $5 {Objectively not best, but does a
decent job at preventing Ne5} (23. Nce2 {Is probably the best attempt at
saving the game.}) 23... Ne5 $2 (23... e5 24. Nde2 exf4 25. gxf4 Qxc4 {And
Black is clearly much better}) 24. fxe5 dxe5 {Thanks to the f1 bishop, this is
not nearly as strong as if Black had played Ne5 earlier.} 25. Nxe6 $1 fxe6 26.
Qe3 Rd4 $1 27. Kh2 Rcd8 28. Qf3 (28. Be2 Qe7 {And Black is slightly better,
but White can still fight}) 28... Nf6 ({Also strong was} 28... Qe7 29. b5 axb5
30. axb5 Bh6 {And Black threatens to infiltrate in d2}) 29. Nb1 $2 Rxe4 $17 (
29... Nxe4 $1 30. Bxd4 Ng5 31. Qg4 Nf3+ $19) 30. Rxe4 Nxe4 31. Rxd8+ Qxd8 32.
Qg4 $2 (32. Bg2 $1) 32... Ng5 33. h4 Nf3+ 34. Kh3 Qd1 35. Qxe6+ Kf8 36. Bg2 {
And now Black has a single winning move :} Ng5+ 0-1
