D.Browns v HV (Honley Liberal Club), 2006
Round 1
|
1.c4 e6 2.Nf3
c5 transposing into an English symmetrical
defence, which can also arise from Reti opening. 3.Nc3 Nc6 Here Nf6 is more usual. | ||
|
[3...d5 4.cxd5 exd5
5.d4 Nc6 6.g3
Nf6 7.Bg2 Be7
8. | ||
4.d4  This is more forcing than the slower, positional g3 move. | ||
| [4.g3 Nf6 5.Bg2 d5 6.cxd5 would be a Tarrasch defence.] | ||
|
4...cxd4 forced, White was threatening
d5. 5.Nxd4 Bb4 | ||
| [5...Nf6 is the English Symmetrical 4 Knights variation.] | ||
|
[5...a6 is possibly best,preventing Nb5.
It can transpose into the Kan/Paulsen variation with c4.e.g.... 6.e4 | ||
| (6.g3 Nf6 7.Bg2 is safer,72% White.) | ||
| 6...Qc7 7.Be3 is 63% White.] | ||
|
6.Ndb5 This has scored 67% for White.
The threat is Bf4. 6...a6 7.Nd6+ Bxd6 | ||
| [7...Ke7 8.Bf4 has scored 94% for White !] | ||
8.Qxd6  Now Black is crocked on the dark squares, and has lost a move compared to the English Symmetrical 4 Knights, as he has made 2 moves with his Bishop. In the 4 Knights, Black would already have a Knight on f6 in this position. 8...Qe7 novelty | ||
|
[8...Nge7 preparing to castle is best. 9.e4 | ||
|
(9...Qa5 10.Be2
Qe5 11.Qxe5 Nxe5
12.f4 N5c6 13.Be3
d5 14.cxd5 exd5
15.exd5 Nb4 16.Rd1
Nf5 17.Bc5 a5
18. | ||
|
10.Bd3 Ng6
11. | ||
|
9.Qg3 ! f5
10.Bf4 ! The
threat of domination with Bd6 provokes e5. Nf6 ?! | ||
| [10...Qf6 !? allowing Nge7 looks better.] | ||
|
[10...e5 is the move I expected, but Black
concedes another square - the d5 square for the White Knight. Black rejected it because of .. 11.Nd5 | ||
| (11.Bg5 is also playable.) | ||
| 11...exf4 12.Qc3 ! Qf8 13.Nc7+] | ||
11.Bd6 Qf7
12. Black is probably already lost positionally | ||
| [12.e3 may be better, but I already envisage the e4 break.] | ||
|
12...Ne7 preparing to castle. 13.f3 !This cuts out any Ne4 move and prepares a possible Na4 and Nb6 option. 13...Nh5 ?This just loses another tempo. 14.Qh4 ! Now Ng6 would drop the h5 Knight, and castling would lose the other Knight so an ignominious retreat is called for. 14...Nf6 best move ! 15.e4  ! Now Black is faced with pawn to e5 threat, and his pieces are squashed into complete disarray. He is unable to castle. However, I had to calculate this carefully as it is, in fact, a pawn sack. 15...Ng6 | ||
|
[15... | ||
|
16.Qf2 fxe4
17.fxe4 Ng4
18.Qxf7+ Kxf7
19.Be2 Black cannot go into f2 because
of a Rook pinning it on the f file. 19...Ne3 20.Rd2  ? even though this wins, I did not realise that Rd3 is stronger as the Rook can go to h3. | ||
|
[20.Rd3 is a forced win. 20...Nxg2 | ||
| (20...Nxc4 21.Rf3+ wins) | ||
| 21.Bh5 N2h4 22.Rh3 Kg8 23.Rf1 b5 24.Rxh4 wins.] | ||
| 20...Re8 ?! | ||
|
[20...b5 is forced as White has Na4 and
Nb6 otherwise. 21.cxb5 Rd8 22.h4 axb5 23.h5 Ne7 24.Rd3 Nc4 25.Rf1+ Ke8 26.Nxb5 Black is lost.] | ||
| [20...Nxg2 21.Rf1+ Ke8 | ||
| (21...Kg8 22.Na4 is an easy win.) | ||
| 22.Na4 and Black does not have an adequate defence to Nb6.] | ||
|
[20...Rd8 21.Rg1 and
Black cannot save his e3 Knight from the Bc5 threat. | ||
| (21.g3 and Rd3 etc also picks up the Knight.) | ||
| 21...b5 22.b3 bxc4 23.bxc4 Bb7 24.Bc5] | ||
|
21.b3 freeing the King Bishop to go
to h5. | ||
|
[21.Rg1 may be simplest win, threat Bc5
picking up the Knight. 21...b5 22.b3 and Black cannot prevent Bc5 winning.] | ||
| [21.g3 b5 22.b3 with Bc5 to follow also wins.] | ||
|
21...Nxg2 22.Bh5
e5 ? Black is losing material anyway,
but this is tantamount to resigning. | ||
| [22...N2h4 loses to 23.Na4 | ||
|
(23.Bg3 also wins. 23...Ke7 24.Bxh4+ Nxh4 25.Bxe8 Kxe8 26.Rf1) | ||
| 23...b5 24.Nb6 Bb7 | ||
| (24...Ra7 25.Bg3 wins.) | ||
| 25.Nxa8] | ||
|
23.Rxg2 Black is a piece down, and
has a hopeless position. 23...Re6 24.Rf1+ Rf6 25.Rgf2 Ke6 26.Rxf6+ gxf6 27.Bxg6 hxg6 28.c5 b6 29.Nd5 threatening mate on f6. 29...f5 forced 30.Nc7+ Kf6 31.Nxa8 Bb7 32.Nxb6 1-0 | ||
