{The following win really set up Moulthun's SIO victory by putting him in the
clear lead (after co-leader Nisipeanu only drew his game).} 1. e4 c5 2. Nf3 e6
3. d3 b6 $5 {This is already a sign that Black wants to play the opening
creatively.} 4. Nbd2 Bb7 5. g3 d6 6. Bg2 Nf6 7. O-O Be7 8. h3 {It is hard to
see how this move helps White.} (8. e5 dxe5 9. Nxe5 Bxg2 10. Kxg2 {would be a
more logical attempt to press, though the endgame after} Qd5+ 11. Qf3 Qxf3+ 12.
Ndxf3 Nd5 13. a4 f6 14. Nc4 Nc6 {is already completely fine for Black - I
would even prefer his chances due to his extra space.}) (8. Re1 O-O 9. c3 Nc6
10. d4 {probably makes the most sense of all.}) 8... Nbd7 9. Qe2 O-O 10. a4 a6
(10... Qc7 {immediately connects the rooks, but in such a non-confrontational
position Black can afford to take time gaining some queenside space right off
the bat.}) 11. c3 (11. b3 b5 12. Bb2 {is a more harmonious deployment, though
after} e5 $1 {Black has no problems; if White pushes for f4 with} 13. Nh2 {,}
Re8 14. f4 exf4 15. gxf4 c4 $1 16. bxc4 bxc4 17. Nxc4 d5 {is a nice
counterstrike at the centre.}) 11... b5 12. Nh2 (12. axb5 axb5 13. Rxa8 Qxa8 {
is a favourable trade for Black as he now gets the open a-file and stops White
playing a quick d4. So White correctly plays on the side of the board where he
is stronger.}) (12. d4 {occupies the centre, but then it is hard for White to
develop the c1-bishop as the d2-knight is tied to defending the e4-pawn.} Qc7
13. e5 dxe5 14. dxe5 Nd5 {for instance would just leave the e5-pawn as a
target for Black's pieces.}) 12... Qc7 13. f4 bxa4 {This seems a small
concession, splitting the Black pawn chain.} (13... e5 14. f5 {seems a
promising change in the structure for White, but Black can play the strong} c4
$1 {to make the e4-pawn backward, and} 15. dxc4 bxc4 16. Nxc4 a5 $1 (16... Nxe4
17. Bxe4 d5 {is also OK mind.}) 17. Nd2 Qb6+ 18. Kh1 Rfc8 19. c4 Nc5 {gives
Black a very strong queenside initiative - White's pieces are tied to
defending all the weak pawns while Black penetrates the weak squares left
behind by those pawns.}) 14. Rxa4 Rfe8 15. Ra1 Bf8 {Black is preparing his
defences for the attack with ...g6 and ...Bg7, but after} 16. g4 $1 {White
definitely has the initiative.} g6 (16... Nb6 17. g5 Nfd7 {borrows an idea
from the Scheveningen, but I don't trust a lone bishop with the safety of my
king.}) 17. c4 {This is a positional mistake as it unnecessarily weakens the
d4-square.} (17. Bf3 Nb6 18. g5 Nfd7 19. Ng4 {followed by e5! is how I would
build up the attack. Black is yet to generate any counterplay on the other
wing.}) 17... Bg7 18. Ndf3 Nb8 $1 {A clever manoeuvre: after} 19. Bd2 Nc6 {the
knight will be ready to later come to the d4 or b4 outpost.} 20. Bc3 e5 (20...
Nd7 21. Bxg7 Kxg7 {is a positionally favourable exchange for Black, but after}
22. g5 {and Ng4 he should take great care not to get mated.}) 21. fxe5 {A
strange move as after Black's recapture his e5 and c5-pawns are as good as
White's c, d and e pawns.} (21. f5 {is the obvious reply, to deprive Black of
a pawn break and press on with the kingside attack.}) 21... dxe5 22. Qf2 Nb4
23. Rfd1 Rad8 (23... Nxd3 24. Rxd3 Nxe4 25. Qe1 Nxc3 26. bxc3 e4 27. Re3 Rad8 {
followed by ...f5 would have been a strong sequence - all of White's pieces
look stupid now. But Black prefers to play more positionally.}) 24. Qe2 h5 25.
g5 Nh7 {With the kingside closed, White won't ever get a checkmate, even if he
can somehow arrange a sack on h5.} 26. Nf1 Nf8 27. Ne3 Ne6 28. Bxb4 (28. Nd5
Bxd5 29. exd5 Nf4 {is very cute, but after} 30. Qe4 {I don't see how Black
cranks up the pressure.}) 28... cxb4 29. Nd5 Qd6 30. Qe3 Nd4 (30... Nf4 {is an
interesting idea, as White can't take the knight without the g7-bishop
breathing fire down the long diagonal.}) 31. Qf2 (31. Nxd4 exd4 32. Qf4 Qxf4 {
(else Nf6 will be quite annoying)} 33. Nxf4 {was White's chance to come out
unscathed - with Black's queenside pawns isolated and vulnerable, White will
take the initiative on the queenside.}) 31... Bxd5 $1 32. exd5 (32. cxd5 Nb3
33. Rab1 a5 34. Nd2 Nxd2 35. Rxd2 a4 {was still much better for Black as
White's bishop is effectively a prisoner, while Black is up a pawn on the
queenside and can activate his prelate to c5 via. f8.}) 32... e4 {A neat trick
- if Nxd4 Black has e3!.} 33. dxe4 Nb3 34. Ne1 {Sacrificing the exchange like
this is hopeless, but} (34. e5 Bxe5 35. Nxe5 {(to stop ...Bg3!)} Rxe5 {still
picks up a pawn due to the double threats of ...Nxa1 and ...Rxg5.}) 34... Nxa1
35. Rxa1 Qe5 (35... Rc8 36. Rc1 Qe5 {was more precise, so that after} 37. Nd3
Qxg5 {, compared to the game the rook on c8 attacks the c4-pawn.}) 36. Nd3 Qxg5
37. Rf1 {A blunder; instead} (37. Kh1 {followed by advancing the c-pawn would
have given White real compensation in his connected passed pawns.}) 37... Rxe4
38. Qxf7+ Kh7 {Now White's king is unable to resist the pillaging Black pieces.
} 39. Qc7 Rde8 40. d6 Rd4 {Here or on the previous move, ...Re2 would have
been pretty strong too.} 41. Rf7 Rg8 42. Nf2 Qc1+ 43. Bf1 Rf4 {Preparing ...
Rxf7 and ...Rf8, after which it is all over.} 44. b3 Rxf7 45. Qxf7 Rf8 46. Qe7

{In the next round the two stars of the SIO - Moulthun and Junta - agreed a
fairly early draw to conserve energy for the crucial penultimate round. For
those of you who haven't heard of the SIO before this post, there are two
rounds a day in this nine round tournament and each round can go for six hours
- so even hardened professionals can become fatigued from this schedule,
especially after playing the same schedule in the Doeberl Cup just beforehand!

{I attended this round of the SIO in person (I didn't play the tournament as I
fell ill just after the Doeberl Cup) and it was a good round to visit as this
game was very interesting and Junta Ikeda broke a live FIDE of 2400 on the day!

the pin can later be broken with f3, if he wants.} e6 9. O-O Be7 10. h3 (10.
