1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 {My opponent played the King’s Indian.} 4. e4
d6 5. Be2 O-O 6. Be3 e5 7. d5 a5 {The Semi-Averbakh variation.} 8. g4 Na6 9. h4
Nd7 {My opponent played 9...Nd7 which was a little odd because the normal move
is 9...Nc5, and one possible line that could happen is 10.f3 h5 11.g5 and
Black has a few choices here.} 10. h5 Ndc5 {I took advantage of the inaccuracy
...Nd7.} 11. Qd2 f5 {11...f5 here seems like a mistake because after} 12. hxg6
hxg6 13. gxf5 gxf5 14. f3 {the g- and h- files are both open for me to attack.}
f4 15. Bf2 a4 16. O-O-O a3 {An interesting move because it sacrifices a pawn
to create weaknesses in my queen side. I think that it is a possible option to
take the pawn here, but I did not want to give my opponent any counterplay, so
I decided to ignore.} 17. b3 Nb4 18. Bxc5 {18.Bxc5 was a mistake because in
the game, I did not want any tactics such as ...Nxa2+ or ...Nxb3+ to happen to
me in the future when I might be caught unguarded, so I decided to simplify.
Some better moves that I could have played were 18.Kb1 or 18.Nh3.} dxc5 19. Bf1
Rf6 {I wanted to maneuver my bishop to h3 so I could trade his important
light-squared bishop.} 20. Bh3 Bxh3 21. Nxh3 Rg6 22. Qe2 Qf6 {My plan was if
my oponent played 22...Rg3 next, I could go 23.Nf2 and play Ng4 next. After 23.
Nf2, if he played ...Rg2, then I can go Qf1 and next move Ng4.} 23. Rdg1 Rxg1+
{This move was a mistake because after Rxg1, I take control over the g-file
and I can play Ng5 and Ne6 and win easily. Also, the game was going on for
almost four hours now, and the game started in the late afternoon, so I was
starting to get tired. Because of that, I nearly offered a draw after 23.Rdg1,
but I stopped myself and decided to play on.} 24. Rxg1 Rd8 25. Ng5 Rd7 26. Qh2
Qh6 27. Qxh6 Bxh6 {Now it only takes a little more precision to win the game.}

These two games were played in the recent States Cup Online team competition.
My first and second games from the match Oregon vs. Arizona. The time control
was 15 minutes with (only) a two second increment added. For me this is a fast
time control, especially when things get down to that two second increment.} 1.

e5 Nh6 10. e6 {Running Black over right away is definitely a reasonable idea
in this sort of Modern Defence position. However, expending a tempo on the
defensive 6.a3 does not jive with the aggressive 10.e6 and 11.Ng5.} fxe6 11.
Ng5 Nf5 {An important resource: Black is able to respond aggressively in turn,
rather than having to grovel defending e6 by ...Nf8.} 12. Bf2 {A good moment
to expend a couple of those precious 15 minutes trying to calculate just what
is going on here. My instinct was Black just had to stand well, and I was
right, though not the way I played it.} Bxd4 ({After the game, with plenty of
time and that infernal computer to help, everything looks so obvious:} 12...

cleared after the opening and he is realizing just how badly it has gone for
him. A nice, smooth victory with Black to start the match.  That is what I
thought during the game, after the game, and as I started to carefully analyse
the game the next day. When that infernal machine pointed out something we
both totally missed at the board -- and might have missed even in a careful
post mortem -- do you see it?} 18. Ng5 (18. Qxf5 $3 {captures the knight and
totally turns the tide.}) 18... Rf8 {Now everything is back where I thought it
was: my entire army plays, his king is in trouble, his rooks do not
participate, without backup his knight and queen cannot hurt me.} 19. Nxh7 Ne3

{Back in the old days, in queen pawn openings such as this one, all the
chessmasters knew that White's c pawn belonged in front of the Nc3, not behind
as here. One of the things people knew back then that turned out not so true
as they thought.} Nf6 3. Bg5 d5 4. e3 {I had faced this myself earlier in the
States Cup, with the Black pieces versus Kiewra of Southern California. He got
a nice position, making straightforward easy moves, and so I figured I would
try it from the White side.} (4. Bxf6 {is (or at least was) more familiar to

someone who plays the Dutch myself, I once read a very pithy comment
concerning just what can go wrong: "At some point, Black's best move is to
play the f5 pawn back to f7!" In other words, unless the rest of Black's army
coordinates and manages to make some sort of use of that first move advance,
it can amount to nothing more than a weakening of the pawn structure. We see
something of that here. Having played c4, however belatedly, White is back to
a "normal" queen pawn formation, but one in which Black's f pawn advance does
little but weaken the e6 pawn and the e5 square.} Qd7 {Breaks the pin on the
knight but Black remains behind in development.} 11. Bxf6 Rxf6 12. cxd5 Qxd5

very far behind in development and his position is clearly dire. But as so
often in such positions it remains a challenge to work out: just how to make
progress from here? I choose (or one could say I am seduced) by a fanciful
path, sending my knights around the edges of the board.} (16. Ng5 {and taking
the h pawn}) (16. Bxa6 {This possibility totally escaped my radar at the board}

certainly looked logical and strong. However, it is wrong and gives away my
advantage. I am merely trading one good diagonal for another. The machine

unusually with the bishop and intending to capture it with Nh5. A good example
of the subtleties than mark the difference between a fast game and a slow one.
Chess as a game of thought, rather than of reaction.}) 25... Nd8 {Black is
close to equalizing, his main problem being the weaknesses resulting from that
first move of 1. ...f5. He needs to find a few good, accurate moves to stay in
the game. And without thinking too much: remember we are playing at 15/2. This
backwards move 25. ...Nd8 is a step in the wrong direction.} (25... Bb8) (25...
