06.10.06 - Openings at the 2006 Canterbury/Box Hill OPEN tournament
- by Trevor Stanning: Round 2:
Zhigen Wilson Lin v Mirko Rujevic was Centre Counter
(Portuguese var.); a favourite of Michael Gluzman who has won
this event previously. Lin had the advantage of a mobile
queen-side majority (2 v 1), together with q-side space. He
needed a plan that would cause Rujevic’s pieces to be tied down
to some defence. The plan remained undiscovered and Rujevic
showed how quickly an IM could move major pieces into
threatening positions given a free hand.
Sam Chow v Thai Ly was a passive Queens Indian that developed
into a Marozy Bind set-up with Sam having the added advantage of
solving the light-squared bishop problem through an exchange.
This left Black with a light square weakness on c6 which proved
fatal as Sam used this as a transfer square for his knight. The
knight exchanged for the black-square bishop on e7, and with
this piece missing Thai had no way of defending d6.
Rothlisberger v D Stojic reminded me of one of those Korchnoi
games where as Black he will grab a proffered pawn and hang onto
it though suffering all sorts of positional concessions. The
pawn remained right into the early end game and of course
assumed more importance with each exchange. An intriguing
tight-rope game.
Rukman v Tony Davis was an odd variation where white did not
follow the usual strategy of a3-a4 followed by Ba3. Black seemed
unsure of where to proceed to place pressure (g-file or q-side).
Eventually Black castled q-side and collapsed rather quickly as
he had no answer to the knight that established itself on the
black square d6; his white-squared bishop was a passive
on-looker.
I often struggle to follow Scot Sharman’s thought patterns
and very rarely can I understand Leon Kempen’s intricate moves.
So, when it comes to Sharman v Kempen I think we move on.
Round 1:
On board 1 Shane Lawson allowed Sam Chow to proceed with his
favourite French defence, and the Advance variation would have
been comfortable ground for Sam. Shane jettisoned the pawn on d4
with his 8th move to castle and the compensation was never
enough to hold off Sam’s accurate strong play.
The same French Advance was seen on board 2 with the stronger
player, Dusan Stojic, on the white side against Zjelko Podvorac.
Black’s 5th …h6 was a crucial waste of time and allowed White to
castle without having to give a concession while having the e5
pawn nicely established. White’s a-pawn got passed with a nice
tactical play and the run-away gave Black more problems than he
could solve.
And again a French on board 3 but this time along classical
lines instead of Advance. It looked as though Peter Schulzer
thought that exchanges were helping him against the stronger
player, Chris Wallis, but essentially he was just speeding the
development of Chris’ pieces with the inevitable attacking
advantage with Chris. The minature was over in 23 moves.
On board 4 Dirk Vielsakaeker v Serif Tuglaci was a
symmetrical English that quickly became a Marozy bind. Serif
thought he was winning a pawn but instead he just traded the
e-pawn leaving his d pawn backward, isolated and on a half-open
file. This was enough of a hinderance to cause his position to
deteriorate.
On board 6 Rolf Exner started off with ideas of a Slav
defence, but soon switched to Queens gambit accepted, but at the
cost of a tempo. Rukman Vijayakumar had soon isolated Rolf’s d4
pawn and Rolf’s need to devote pieces to the protection of this
pawn allowed Rukman to switch to a mating attack on g2.
Board 7 saw Leon Kempen play the Tarrasch line against the
French Defence, and he had all the attacking options as Jason
Tang got into a logjam of pieces on the Q side. Inevitable
result was a win to Leon.
Well, that is the review of the top boards for round 1. No
upsets expected in round 1 and none occurred. Each week, your
aisle-side-patzer will give his comments on what the top boards
are using to open with at the OPEN.
