1985-08-02 - Lane, Gary 0-1 Mordue, Tyson
Tyson's debut at the Paignton Congress against Paignton's finest player. Future IM Gary Lane allows his dark-squared Bishop to be swapped for a Knight in a c3 Sicilian. As the position opens up Tyson takes the initiative on the dark squares, and he quickly proves that if White hasn't developed his other bishop then he's going to be weak on the light squares as well. It's a wonder that Lane avoided material loss for as long as he did.
[Event "PAIGNTON PREMIER"] [Site "?"] [Date "1985.08.02"] [Round "2"] [White "Lane, Gary"] [Black "Mordue, Tyson"] [Result "0-1"] [ECO "B22"] [Annotator "Mordue,Tyson"] [PlyCount "54"] {Gary Lane was a strong junior who won the WECU senior title several times. He went on to become an IM in 1987, is a author of many chess books and now lives in Australia. This game was played in his home town and was Tyson's first Paignton Premier. The original notes are by Tyson marked TM.} 1. e4 c5 2. c3 d5 3. exd5 Qxd5 4. d4 e6 5. Nf3 Nf6 6. Na3 {"Lane-Mordue, Exeter 1984, continued 6 Bd3 Nc6 7 0-0 cxd4 8 cxd4 Be7 9 Nc3 Qd6 when Black maintained equality and scored a comfortable draw." TM.} Nc6 {"Better is 6...Be7 and if 7 Nb5 Na6! is okay for Black." TM. I originally gave 6...Nc6 an ? but it's merely a move-order blip. By the same token 7...Na6 doesn't reserve an ! This may have been the first time I'd met 6 Na3 but I made sure to get the move-order right in future games.} 7. Nb5 Qd8 {The most popular move. A few players have essayed 7...Qd7 but this is probably the square Black wants for the c8 Bishop. One unfortunate played 7...Qe4+? and lost the a8 Rook. After rhe text 8 Bf4 is answered comfortably by 8...Nd5 9 Bg3 and, if Black wants, 9. ..a6 ejecting the Knight. The most common reply is 8 dxc5 and then 8...Bxc5 9 Qxd8+ Kxd8 10 Bf4 Ne4 should be okay for Black. Nevertheless, this variation is the reason I made sure that in future games I was playing 6...Be7 and 7... Na6.} 8. Be3 $2 {This is poor move because at the very least Black can play 8.. .a6 9 Na3 cxd4 followed by ...Bxa3 breaking up White's Queenside. This certainly happened in one game on my database. With my reluctance to play Pawn to Rook Three I looked for another move.} Nd5 $5 {"I had discussed this variation before the round with Jeremy Menadue and he had mentioned a game of Hungarian GM Adorjan's where he had played ...Ng4. I believe the Black Queen was still on d5 then, but here I took the option of going to the natural blockading square on d5. Now White cannot take on c5 which he should have done last move." TM. This move was Deep Rybka's second choice after the afore-mentioned 8...a6. The irony is that in that line Black gives up his dark-squared Bishop to inflict weaknesses on White, while here I'm going after White's dark-squared Bishop to do the same! The engine says White should still play 9 dxc5 but after 9...Nxe3 10 Qxd8+ Kxd8 11 fxe3 Bxc5 Black has a comfortable game which I think deserves better than Deep Rybka's evaluation of a mere +0.12 to the second player.} 9. c4 $6 {"Normally White can allow ... Nxe3 because his centre is strengthened thereby, but by playing c4 White loses control of d4 and b4. 9 Bd2 is a book move but best is probably the simple 9 Be2." TM. The nearest I can find to the current position in any book is a transposition involving 8...cxd4 9 Nbxd4 Nd5 which occurred in Meulders-Sosonko, Amsterdam Zonal 1978 and did feature 10 Bd2. Sosonko squeezed out a win in a Rook and Pawn ending in 57 moves. In this game after 9 Bd2 Deep Rybka suggests the simple 9...a6 10 Na3 cxd4 11 cxd4 Be7 with a clear advantage to Black. The Bishop doesn't belong on d2 nor the Knight on a3. Upon 9 Be2 Deep Rybka belives Black can safely adopt the following sequence: 9. ..a6 10 Na3 cxd4 11 cxd4 (if 11 Nxd4 Nxe3 just leaves White with a shattered Pawn structure) 11...Bxa3 12 bxa3 Nxe3 13 fxe3 Qa5+ and 14...Qxa3 winning a Pawn. Note how Black takes care to play ...a7-a6 before playing ...c5xd4 so that the b5 Knight doesn't have the chance to retreat to the better c3 square, but after the text Gary's can now go to c3 is pushed.} Nxe3 10. fxe3 cxd4 11. exd4 Bb4+ 12. Nc3 O-O {Now Black has a small but clear advantage in an open position where he also has the Bishop pair.} 13. Qd3 $2 {"Actually making Black's intended reply even stronger! Best is probably 13 Be2 but Black can comfortably reply 13...Qa5, or 13...Qb6 followed by 14...e5 or 13...e5 first." TM.} e5 $1 14. O-O-O {"Not 14 d5 for 14...e4 wins. Taking on e5 meets 14...Qa5 followed by ...Bg4 and centralising the Rooks after which Black has enormous pressure. White can be stopped from Kingside castling simply by ...Bc5. In the game he tries the Queenside but it's just as draughty there." TM. Not any better is 14 Nxe5 Nxe5 15 dxe5 Qh4+ 16 g3 Qg5 with a fine position for Black. After some thought Deep Rybka chooses 14 dxe5 Qa5 15 Be2, but after 15...Nxe5 16 Nxe5 Qxe5 17 0-0 Bxc3 Black has a clear advantage particularly after bringing his Bishop to e6 to target the weak Pawn on c4. Deep Rybka puts it at +0.82. Notice how much damage is being done on the dark squares, a direct result of the elimination of White's Queen's Bishop. After White has castled Queenside the engine has Black's plus at an equally satisfactory +0.75. } exd4 15. Nb5 $2 {"Walking into a pin on the d-file. White was trying to avoid 15 Nxd4 Nxd4 16 Qxd4 Qxd4 17 Rxd4 Bxc3 18 Bxc3 when Black has a very favourable ending, but the coming middle-game is even worse for White." TM. Deep Rybka puts an evaluation on this ending of +0.45 for Black after 18...b6. It prefers the middle-game with 15...Qa5. After the text we are now back to the ironic situation of White trying to justify his Knight excursion to b5. and Black trying to time his ...a7-a6 to maximum effect. In other words the opening motif repeating itself!} Qf6 16. Nfxd4 $2 {"This is probably worse than 16 Nbxd4 because Black now has a threat of ...a6 winning a piece. However, if 16 Nbxd4 Rd8 17 Qb3 Qf4+ 18 Kb1 Nxd4 19 Qxb4 (if 19 Nxd4 Rxd4 20 Rxd4 Qxd4 21 Qxb4 Qd1 mate.) 19...Bf5+ 20 Bd3 Nxf3 wins or here 18 Kc2 Rxd4 19 Nxd4 Qxd4!! Better is 16 Ndxd4 Rd8 17 Qe4 Nxd4 18 Nxd4 (if 18 Rxd4 Bf5 wins) 18... Qg5+ 19 Kc2 (if 19 Kb1 Bf5 wins) 19...Bg4 with a big advantage. If here 20 Be2 Rxd4 21 Rxd4 Bf5." TM. A reasonable bit of analysis that needs expanding at two points, or rather at the same point twice! In the line 16 Ndxd4 Rd8 17 Qe4 Nxd4 18 Rxd4 Bf5 wins the engine carries on with the amusing 19 Qh4 Qxh4 20 Rxh4 Bc5 threatening 21...Be3 mate and if 21 b3 Ba3 is mate instead! As 21 Nd2 is still met by 21...Be3 winning a piece White is resigned to the miserable 21 b4 giving up a Pawn. In the same line 16 Ndxd4 Rd8 17 Qe4 Nxd4 a different recapture with 18 Nxd4 meets a symmetrical yet prosaic reply in 18... Bc5. If the desperate 19 Bd3 threatening h7 then simply 19...Qh6+ and 20... Bxd4. I think that it's fair to say that White has no realistic chance of recapturing on d4 safely, and that he should play 16 Qe4 and 17 Bd3 just for the sake of getting his King's Bishop out.} Rd8 17. Qf3 {"The point of taking with the f3 Knight was to free this square for the Queen, but Black can win material with a nice Queen sidestep." TM. If instead 17 Qe4 Nxd4 18 Rxd4 Qg5+ 19 Qf4 (if 19 Kb1 or c2 Bf5 wins) Qxf4+ 20 Rxf4 Bd2+ wins the Rook, while 18 Nxd4 Bc5 and all of 19 Nb3, 19 Nb5, 19 Nf3 and Ne2 are met by a combination of ...Bc8-f5 and ...Rd8xd1+ as appropriate. 19 Nc2 just simply loses a piece to 19...Qg5+. Black hardly needs to calculate here. His moves are coming easily and naturally.} Qg5+ 18. Kb1 Bg4 {A fine entry into the game. White's Rook is in trouble, his Knights are in bother and his Queen keeps running around to no good effect. How long can he continue to avoid losing material?} 19. Qg3 a6 20. Be2 {"If 20 h3 axb5 followed by ...Nxd4 wins a piece, or 20 Nc7 Bd6." TM. Upon 20 h3 Deep Rybka suggests 20...Bf5+ 21.Nxf5 Rxd1+ 22.Kc2 Qd2+ 23.Kb3 Na5+ 24.Ka4 axb5+ 25.Kxb5 Bf8 to guard the mate on g7 and apparently mating in seven moves as well.} Qg6+ 21. Bd3 Qh5 {"And now White has a whole Rook en prise as well." TM.} 22. Nxc6 bxc6 23. Rdf1 axb5 {Finally some material gain!} 24. cxb5 Be6 {"I spotted 24...cxb5? 25 Rf4 forking the Bishops but missed the superior 24...Qd5!" TM. Deep Rybka says that 24...cxb5 25 Rf4 Qd5 is strong too but 24...Be6 is the second-best move and tidies up.} 25. b3 cxb5 26. Qe3 Bc5 {Switching the Bishop around to d4 before thinking of sacs on a2 or b3.} 27. Qe4 Bd5 {Convincing enough. White resigned.} 0-1
