was playing against the defending champion, Paul Leblanc, who beat him the
year before in a seemingly drawn game. This was his chance of getting the
revenge he had been waiting for. He was having a very good tournament: he had
just drawn against the 3-time champion Roger Lebrun and his unit (CFS Leitirm)
was in the top 3. However, he knew things would only get tougher as the

{The following was one of my more interesting games at Arnprior. After an
unambitious opening by White, a fairly equal middlegame arose in which I
invited my opponent to create an imbalance by trading a knight for a bishop,
with a basically symmetrical pawn structure. Eventually a fairly
complicated endgame occured in which I had pair of knights against bishop and
knight. We each made a number of mistakes, and at one point I missed a win in
mild time trouble, relative to my opponent's. The final significant mistake
allowed me to win a piece, and the game.} 1. Nf3 d5 2. d3 Nc6 3. Nbd2 e5 4. e4
Nf6 5. g3 {After this Black can immediately demonstrate at least equality, in
dry fashion. Instead, playing a Reversed Philidor's Defence by 5.Be2 (or 5.c3
first), in spite of its modest appearance, may offer somewhat better hope for
more than equality, as for one thing if Black trades on e4 then the B/e2 is
released and is not needed on g2.} dxe4 6. dxe4 {Diagram [#]} Bc5 ({Even} 6...

possible Black might claim a tiny edge. Instead I offer my B for a White
knight, hoping one of my knights might outshine the White B better than my
good B might ever get the chance to. It's often better to have a knight vs. a
bad B, given such a choice, as for one thing the knight can operate on both
coloured squares, and for another it thus may be harder to swap the bad B off.}
14. Nc5 b6 15. Nxe6 Qxe6 16. b3 {In spite of White's slightly "bad" B the

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 {When I first started to play, I choose
the g3 lines against the King's Indian. Back then it seemed to me that the
mainline "Mar del Plata" lines, even if objectively favourable for White, were
too easy for Black to play. Strategically it seemed like a no-brainer: prep
your pawn storm and sac a piece on the White pawn chain. Tactically it also
seemed too easy: Black has so little space that there are really very few
choices about where to put the pieces, and so even a little familiarity with
it goes a long way for Black. I still think that's more-or-less right (perhaps
less right for those facing professional-quality opening preparation), but
last year I decided to change my White repertoire, and that meant no g3 here.}

crucial defender. ...Nc6, threatening Na5, was better.} (8... Nc6 9. Nc3 Bb4

resource in 9...Be7. White can again try the tempting Bh6, but it wastes time,
allowing Black the opportunity to free himself. After 10. Bxe7 Black stands
better than in the game.} (9... Be7 10. Bh6 Nc6 {Threatens Nxd4 and Nxc4

compensation in the form of the Bishop pair but his King is weak and White
should be able to engineer advantageous exchanges.} (10... Qxc4 $6 11. Qxc4

move maintains the tempo of the game, allowing White to castle immediately and
press on with the attack. However Bh4 may have been wiser. The Bg7 will be of
less use in the defence than its opposite number will be in the attack

this inaccuracy and the blunder that follows it. 22. Nc5+ was clearly better.}
