1. c4 c5 2. g3 Nc6 3. Bg2 g6 4. Nc3 Bg7 5. a3 {White chooses a very flexible
approach, opting to expand on the queenside before defining his central
configuration. I've looked at this in the past and I believe the best remedy
is to continue development as normal.} e6 {I like going for a Nge7 setup in
the symmetrical English. This is not bad but the weakening of the dark squares
does invite white's next move.} (5... d6 {has the benefit of forcing white to
play} 6. Rb1 {if he wishes to go for a quick b4, and then black can continue
with} e6 7. b4 Nge7 {and white doesn't have the option of wrecking black's
pawn structure as in the game.}) 6. b4 {This pawn sacrifice is sound when
black has his pawns on e6 and g6. I am very familiar with the ideas because I
play a similar gambit arising from the Grand Prix Attack. If black grabs the
pawn, white will have a dangerous initiative on the dark squares giving him
more than enough compensation. In the Sicilian version, black has several good
ways to decline the gambit, such as b6 and d5, but neither move is possible in
this position because of white's light-squared bishop.} d6 (6... cxb4 $2 7.
axb4 Nxb4 8. Ba3 Nc6 (8... Bf8 {is more precise but white's activity and
development gives him more than enough compensation for the pawn.}) 9. Nb5 Bf8
10. Bd6 {This is the main idea. White threatens to win the queen, so black is
compelled to trade bishops.} Bxd6 11. Nxd6+ Kf8 {A glance will tell you that
white is much better.}) (6... Nxb4 {is the strongest response and something I
considered, but it felt too risky to play considering my opponent likely knew
he what he was doing a lot more than I did.} 7. axb4 cxb4 {White should give
the piece back with a move like 8. d4, leading to an equal position, but what
if he goes for more?} 8. Nb5 $2 Bxa1 9. Qa4 Bf6 10. Qxb4 {Black is going to
suffer on the dark squares, but compared to the 6..cxb4 line, black has an
extra exchange and white's counterattack is not as fast. For these reasons,
black is objectively much better, but the position is quite sharp so I'd say
all three results are on the table.}) 7. bxc5 dxc5 8. Bxc6+ bxc6 {I considered
my position to be a tiny bit worse. White has given up his valuable bishop but
he will enjoy a long-term structural advantage. Black has the bishop pair and
small initiative: currently he has the positional "threat" of Bxc3, returning
the favour.} 9. Rb1 {White lays claim to the b-file, allowing black to carry
out his idea. I was happy to see this; if I was on the other side, I would
relish at the opportunity to keep a healthy pawn structure and play against
the c-pawns throughout the midldegame. I anticipated something like...} (9. Bb2
Rb8 10. Rb1 Ne7 11. Nf3 Nf5 {where black's active pieces and central control
should offset the structural weakness.}) 9... Bxc3 10. dxc3 Qxd1+ 11. Kxd1 {I
did not deem white's control of the b-file to be important because black
controls b7 and b8. I thought black has a small edge here because of his
slight initiative and white's awkward king placement.} Nf6 12. Be3 {I missed
this move. White defends against Ne4 while threatening the c5-pawn.} Ba6 13. f3
{I thought this was a waste of time. It also blocks the knight's natural
development square.} (13. Nf3 {makes more sense.} Ne4 (13... Bxc4 14. Ne5 $14 {
and white takes over the initiative.}) 14. Kc2 Bxc4 15. Rhe1 {It looks like
white has lost a pawn and gone passive, but one of Ne5 and Rb7 is coming,
which is enough to keep the balance.} f6 16. Rb7 O-O $11) 13... Bxc4 14. Bxc5
O-O-O+ 15. Ke1 {I intended 15..Rd7, covering e7 and a7, but then I spotted a
third threat of Bd4, forcing me to change plans.} Nd5 16. e4 {I was pleased to
see this move. White gains space, but loosens his position at the same time.
There was nothing wrong with grabbing the a-pawn, but black has sufficient
compensation.} Nc7 {It took me longer than it should have to see the
refutation of} (16... Nxc3 17. Rc1 Rd3 {I spent some minutes investigating 18.
Rxc3 and 18. Bd4 before spotting} 18. Bb4 {simply attacking and winning the
pinned piece.}) 17. h4 {A clever multi-purpose move. I was already under 20
minutes, so I had to pick up the pace.} h6 {Preparing to meet 18. h5 with 18..
g5, and missing white's main intention.} 18. Rh2 Rd3 19. Rhb2 Rhd8 20. Be7 Re8
{Of course, not} (20... R8d7 $4 21. Rb8#) 21. Bf6 {I had anticipated this
position before playing my 18th move, but what I had failed to realise until
now is that white is threatening a forced checkmate starting with Rb8+. I had
planned 21..e5, which actually does avoid the mate, but loses a pawn in the
process. I tried a different defense.} Na6 $2 {This also loses a pawn, but I
thought it was better than 21..e5.} (21... e5 22. Rb8+ Kd7 23. Rxe8 Nxe8 {
Forced.} 24. Bxe5 {and I failed to see any compensation. c3 and f3 are secure,
and black's pieces are awkwardly-placed.}) (21... Ba6 {is one of the engine's
top recommendations. Rb8+ is harmless.} 22. Kf2 Kd7 {with a roughly equal
position.}) 22. Rd2 $2 {Throwing away the advantage. I'm not sure why white
rejected 22. Rb7.} (22. Rb7 e5 23. Rxa7 {is much better for white.}) 22... e5
23. Rxd3 Bxd3 24. Rd1 Nc5 {Both players had under 10 minutes until move 36, so
we were playing quite quickly.} 25. Bg7 h5 26. Nh3 Bc4 27. Nf2 Kc7 28. Bf6 Nd7
{I intended this anyway, to free the rook. It's nice to gain some time in the
process.} 29. Bg5 Rb8 {I was very happy with my position.} 30. Be7 Rb2 31. Bd6+
Kb6 32. Rd2 Rb1+ 33. Rd1 Rb2 34. Rd2 Rb3 35. Nd3 Rxc3 36. Bxe5 $4 {A fatal
mistake at the time control. Unfortunately, we were playing with analog clocks.
I knew I had under a minute left, but without knowing the seconds, I just
played a move instantly.} Nxe5 $4 {Of course, 37. Rxd3 won immediately.} 37.
Nxe5 Be6 {I fully intended to play for a win here. Black is more active, and
he has the better minor piece.} 38. Rd3 {White might have thought
simplification will ease the defense, but I don't believe this is true.} Rxd3
39. Nxd3 {Now I'm definitely playing for a win! Even if it objectively equal,
black is going to have all the fun.} Kb5 40. Nb2 {Still playing quickly on the
adrenaline of the time scramble, I missed this obvious defense. So black isn't
winning the a3-pawn by force as I first suspected. Oh well. At least he can
put his king on d4.} Kc5 41. Kd2 Kd4 {I thought it would be smooth sailing
from here, but the knight proves its worth as the trickiest piece in the game.}

Kd4 49. Nc1 a4 50. Ne2+ Kc4 51. Nc1 Bh3 {Black's queenside position is optimal,
but he can't force an infiltration on that side alone. Now the principle of
two weaknesses kicks in. It's time to create a distraction elsewhere.} 52. Nd3
Bg2 53. Ne1 (53. Ne5+ {had to be tried, but I was confident of my chances after
} Kb3 54. Nxf7 Bxf3 {Black should be winning, but white has become active, and
anything could have happened in the ensuing time scramble.}) 53... Bh1 54. Kc2
{it looks like white has everything covered. And he does, if he didn't have to
make moves!} f6 {Zugzwang. It's time for white to give something up. Glancing
at my clock, I saw that I had some amount of time between 0 and 120 seconds.
My opponent had more time I think, around three minutes, if not more. I
stopped writing my moves down.} 55. Kb2 Kd4 56. Kc2 Ke3 57. Nd3 c4 {If I
allowed Nxc5, the knight would defend e4 and attack a4. Instead I force the
knight on a much slower path, gaining a lot of time. It probably doesn't
matter here, but in many endgames even a single tempo can make all the
difference.} 58. Nb2 Bxf3 59. Nxc4+ Kxe4 60. Nb2 Kf5 61. Nxa4 Kg4 62. Kd3 Kxg3
63. Ke3 Ba8 64. Nc5 Kxh4 {I don't remember the remaining moves, but they are
not important. I started pushing my pawns and my opponent's flag fell first. I
didn't bother to check how many seconds I had left!} 0-1
