This isn't the sexy modern ...Nh6 line, as recommended in Watson's Play the
French books. But it's strategically complex, and has been played by Kortchnoi,
Petrosian and Bareev, and it is recommended by Moskalenko in his books on the
French. Black's idea is to gain queenside space and then overprotect the
light squares with moves like ...Na5 and ...Nge7-c8-b6 and even ...Bd7-a4.
This will guarantee that White cannot break on the queenside without giving
Black's pieces control and use of the light squares, especially c4. Since it
would be foolish for White to break on the queenside, Black will castle long
and all the pawn play will be on the kingside. White has more space on the
kingside, but will castle that way too, and any pawn breaks (f4-f5 or ..f6)
might open lines for Black to attack.} 7. g3 Na5 8. Nbd2 Bd7 9. h4 {Diagram [#]

with ...b5 or ...d5. When that works -- as it does in this game -- White can
get torn apart on the over-extended kingside. It's nice to see a young player

Dorrance's game from the 2015 WYCC. Adam put in a strong performance and
gainied around 150 FIDE rating points. I decided to annotate his last round
game against a higher-rated player. Adam played quite solidly, and even
outplayed his opponent with the Black pieces and gained some winning chances.

{http://chess.ca/newsfeed/node/689 This year's Montreal Open drew out a
number of inactive players, including FM Goran Milicevic. I chose to annotate
his last round game against a strong expert of the Montreal chess scene, Louis
Robichaud. The game is interesting in that it shows FM Milicevic going for the
quick kill with an early Kingside pawn storm but having his attack parried and
then almost getting into trouble late in the game. There is a lot to learn -
especially from the psychological side (due to the rating difference between
players) - from the following game. In a final round game where the White
player has a significant rating advantage, you know he's playing for the win.
It's interesting to see how Louis neutralizes White's advantage and then has
his own chances to win.} 1. d4 Nf6 2. Nf3 g6 3. Nc3 d5 4. Bf4 Bg7 5. e3 O-O 6.
