dogmatic teenager, I learned from Modern Chess Openings 10 that the "only"
correct way to play this position was 9.f4 and 10.Qe1 with the idea of playing
Qg3 and intimidating Black's king. But over the last 48 years I have seen that
there are lots of ways to interpret the White side of the Sicilian. Austin has
more space and better development, so he isn't under any obligation to start
playing for mate on move 9.} O-O 10. a4 d6 11. f3 b6 {Austin's 11th move

pieces are centralized and he has good control of the d-file}) 15. b4 {Not the
kind of move we would have made back in 1972, as weakening White's control of
the c3 and c4 squares would have been considered positional suicide. Since
then, I have seen some Scheveningen Sicilian games where white plays b4 and
chokes off Black's counterplay. After 12.Rab1 I suspected the b2-b4 push would
come, but I didn't know how to arrange my pieces to prepare for it.} Bd7 (15...

too late. But the engines believe I am equal even if I don't play 20...a5.} 21.

13,0,16,0,16,0,16,0,16,-1011,-1012] Going into round two, the match was tied
with both teams scoring two wins. After a disappointing first round loss
against FM Mark Heimann, I found myself up against National Master James Canty
III with the black pieces. Canty achieved his National Master title in 2009
and nowadays competes in tournaments across the United States in search
International Master and Grandmaster norms. It was clear, before the match
started, that I would have to brace myself for a grueling battle.} 1. e4 c5 2.
c3 d5 3. exd5 Qxd5 4. d4 g6 $5 {Having done a bit of preparation against my
opponent before the match, it was clear that Canty's primary weapon against
the Sicilian Defense was the Alapin Variation, a weapon where he was equipped
with extensive opening preparation. In fact, he even created a video course
titled "The c3 Sicil For The Kill"! Entering his comfort zone, the theoretical
mainlines of the Sicilian Alapin, would be impractical, so I opted for a
lesser known line. With 4...g6, Black aims for an improved anti-IQP structure
where the dark-squared bishop is destined to put pressure against the isolated
d4-pawn. Games in this variation often feature lengthy, positional struggles
rather than sharp, tactical finishes. Black is generally solid in these
structures so therefore, I believe that the system I played in the game is
somewhat underrated and deserves more attention from stronger players.} 5. Nf3

best explanation for this blunder was that Canty was playing under his time
scramble instincts of attempting to "flag" the opponent even though this game
was played with a two-second increment.This circumstance goes to show how
excessive play of bullet chess can be detrimental to one's play even at the
master level.} Rxc6 {White immediately resigned. Clearly, the element of luck
was present in the victory of mine that I just now shared but I am proud of my
defensive play in the earlier phase of the game where I was significantly
behind in development with my queen getting constantly booted around. In
summary, what started as a largely theoretical battle soon transformed into a
back and forth middle-game, dead-drawn endgame, and lastly a heartbreaking
finish for one of the belligerents in this thrilling finals game. This was
crucial for the match situation and delivered a huge psychological blow in
favor of Team Washington. I learned a lot upon analyzing this game and I am
certain that most readers can as well even through the few inaccuracies made
by both players.} 0-1
