Jenkins Trophy NSCC (1.6), 26.08.2015

1.e4 c5 2.Nf3 d6 3.g3
Sicilian Defence, Closed System.

3...Nf6 4.d3 Nc6 5.Bg2 Bg4
To provoke h3, and create weaknesses around the White King.

6.h3 Bd7 7.0-0 Qc8
Luring the King forward. Evans thought this move looked awkward. Which looks more awkward, the Black Queen or the White King?

8.Kh2 g6
Once the Black Bishop arrives on g7 the discovered attack with ...Ng4+ can be lethal.

9.Nc3 Bg7 10.Be3 0-0
Not 10...e5 11.Qd2 0-0 12.Bh6 and the powerful Black Bishop is exchanged.

11.Qd2 Re8
Preventing the exchange of the fianchetto Bishop and protecting the e7 square from a future Knight fork via d5.

12.Bh6 Bh8 13.Rae1
White's intentions are now clear, a full scale Kingside attack.

This move symbolises the Botvinnik Variation, but White's attack is slower as he normally plays Nge2 and f4.

14.Nh4 Nd4
Better is 14...Nh5! 15.f4 exf4 16.gxf4 Ne7 17.a3 d5.

Better is 15.f4 Qd8. After 15.Ne2 Black makes it difficult for White to play the f4 break.

15...Nxe2 16.Rxe2 Nh5
! Now if 17.f4 exf4 18.gxf4 and the White King is exposed, or 18.Bxf4 Nxf4 and the annoying White Bishop disappears. Also, if White tries to attack the King with 17.Qg5 then Black has several resources in 17...f6, 17...Bf6 or 17...Qd8.

17.c3 Qc7
Lining up on the same diagonal as the White King, if White forces the position open with 18.f4.

White starts to get tangled up with his pieces.

Heading for e6 to take control of d4 and wait for the f4 break to come.

Heading for e3 and d5, but the White pieces get in each others way.

Forcing the g pawn forward, as the Bishop cannot retreat to protect h3.

20.g4 Ne6
Now Black has complete control of the dark squares.

Walking away from protecting the h3 pawn. This will prove fatal.

Holding the balance by eyeing up h4 and preventing the Knight from going to e3 and d5.

?? The blunder in time trouble. I'm expecting 22.g5. White has run his clock down to 5 minutes left, and Black has 35 minutes.

! I thought about 22...Qf6 23.Bg2 g5 24.Nf5 Nf4 but the simple way is the best way. White must lose a piece. Note the importance of the Rook on e8, preventing a possible Mate after 23.Nd5 Qxh3+ 24.Kg1 Qxf3 25.Ne7. 0-1
