1984-11-14 - Powney, Colin 1-0 Kilmister, John
Colin Powney gives an excellent display of how to play against your own favourite Black defence with the White pieces. He goes forward all game against poor defence and Black is quickly mated.
[Event "BRISTOL LEAGUE DIV 2"] [Site "?"] [Date "1984.11.14"] [Round "?"] [White "Powney, Colin"] [Black "Kilmister, John"] [Result "1-0"] [ECO "B07"] [Annotator "Mordue,Tyson"] [PlyCount "45"] {Colin Powney was a B team regular for many years and a threat to anyone. John Kilmister was one of a huge bunch of juniors at Keynsham and still plays for them today. The notes are based on Colin's original comments which are marked CRP.} 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. f3 {An aggressive system similar to the Yugoslav attack. Colin played the Pirc as Black so if this is what he plays against it as White then it should be noted. The Pirc was very much in vogue in the late 1970s and early 1980s. If Black plays an early...e7-e5 then there is an analogous line in the Philidor's Defence.} Bg7 5. Be3 O-O 6. Qd2 Nbd7 7. g4 Re8 {"Usually played to allow ...Bg7-h8 after White's Bh6." CRP. The text looks slightly odd but Black needs to challenge in the centre with ...c7-c5 or. ..e7-e5 and the Rook move supports the latter.} 8. h4 e5 9. h5 {9 0-0-0 was played in the game Brunello-Borsato, Italian Ladies Championship 2004. Closing the centre with 9 d5 is also an option then playing the position like a King's Indian Defence but without c2-c4.} exd4 10. Bxd4 d5 $2 {This is not good because at the very least White can simply play 11 Nxd5 Nxd5 12 Bxg7 Kxg7 13 Qxd5 and win a Pawn for virtually nothing. The line may be playable with the Queen's Knight on c6 instead of d7. In the Philidor's Defence there is a line where Black plays ...c7-c5 and then ...Qd8-a5 but once again this is with a Knight on c6 and a swap of steeds on d4 occurs before ...c7-c5. The d6 Pawn is offered as a gambit but White should ignore it.} 11. hxg6 fxg6 {This is the usual recapture in these type of positions. The h7 Pawn can be defended by a Black Knight on f8 but with the h-file completely open h8 becomes a vulnerable square too. Nevertheless Colin very quickly proves that the a2-g8 diagonal is a vulnerable line also.} 12. O-O-O dxe4 $2 {A naive Pawn-grab that Black can't even keep. He had to move the d7 Knight and get developed. Deep Rybka now has White at +2.4 here mainly because White now has Bc4+.} 13. g5 {Deep Rybka considers the immediate 13.Bc4+ Kh8 followed by 14.Nxe4 to be more accurate. This is because 14...Nxe4?? is mate in five after 15.Bxg7+ Kxg7 16.Qh6+ Kf6 (if 16...Kh8 17.Qxh7 mate) 17.Qf4+ Kg7 (if 17...Ke7 18.Qf7 mate) 18.Qf7+ Kh8 19.Qxh7 mate.} Nh5 {Deep Rybka offers 13...e3 as an alternative by trying to deflect the d4 Bishop with 14 Bxe3. However, the engine gives two different lines against 13...e3. A) 14.Qg2 Nh5 15.Rxh5 gxh5 16.Bf6! Bxf6 (or 16...Re7 17.Nd5 wins) 17.gxf6+ Kf7 18.Qg7+ Ke6 19.Bh3+ Ke5 20.Qg5 mate, or B) 14.Bc4+ Kh8 (If 14...Kf8? 15.Bc5+! Nxc5 16.Qxd8 wins an Exchange) 15.Qd3 Nh5 16.Bxg7+ Kxg7 (if 16...Nxg7 17 Qxg6 is crushing) 17.Qd4+ Re5 18.f4 wins. Both lines are convincing but I think Black should try 13...e3 anyway.} 14. Bc4+ Kh8 { "And it's check when the dark-squared Bishops come off." CRP.} 15. Bxg7+ Nxg7 { If 15...Kxg7 then 16.Qd4+: a) 16...Re5 17.Qxe5+ Nxe5 18.Rxd8 Nxc4 19.Nb5 is winning, or b) 16...Ne5 17.Qxe5+ Rxe5 18.Rxd8 Rxg5 19.Rg8+ Kh6 (if 19...Kf6 20.Nxe4+) 20.Be6 wins, or c) 16...Kf8 17.Qh8+ Ke7 18.Qxh7+ Kf8 19.Qf7 is mate. } 16. Qh2 $2 {Getting a bit carried away. Simply 16 Nxe4 gives White a big advantage because of the threat of 17 Nf6, but even better is 16 Bf7 threatening 17 Bxg6. So Deep Rybka coughs up the Exchange with 17...Re6 and after 18 Bxe6 Nxe6 19 Nxe4 White is +3 or so.} Qxg5+ {"Not so much a Pawn lost as one less between me and his King." CRP. However, if you're keeping count White is now two Pawns down, although Deep Rybka says White is still better!} 17. Kb1 Qh5 $2 {This actually loses a tempo, not gains one. Better are either 17...Nh5 to which Deep Rybka goes after the fork on c7 with either 18 Nb5 or 18 Nb5, or 17...Nf8 when 18 fxe4 is the engine's preference. Despite the Pawn minus 19 Qxc7 is a threat and 19 Nf3 follwed by 20 Rdg1 adds more pressure to the Kingside, clearly a line that adds weight to Colin's last comment.} 18. Qg2 exf3 $2 {Yet another move by this Pawn and another mistake! It helps to connect the White Rooks and brings the other White Knight into the game. Deep Rybka first suggests 18...Qe5 but after 19 Bf7 it has to concede the Exchange again. Correcting with 18...Qf5 allows 19 fxe4 and White has an enormous initiative for a Pawn.} 19. Nxf3 Qc5 {"19...Qf5 20 Bd3 must have looked worse - White's attack looked good enough. [20 Nh4 is even better. TM] So now I sit and try to think of an excuse to ignore the attack on the Bishop and, after worrying for a while about Black's possible 22nd, play:" CRP.} 20. Qxg6 {Well Colin, Deep Rybka has White at +10.64 so your judgement is accurate. How's your calculation?} Nf8 {"Forced. Now Queen and Bishop are en prise so give up a Rook." CRP.} 21. Rxh7+ $1 Nxh7 22. Rh1 Bf5 {"A free move. This stops 23 Qxh7 mate but not ..." CRP. 22...Bh3 is Deep Rybka's desperate suggestion. Of course White just takes. Note how 18...exf3? has added grist to White's mill. The f3 Knight stops mate on e1 after 24 Rxh3.} 23. Rxh7# {"And the Bishop's been en prise for 4 moves." CRP.} 1-0
