k This lecture is an edited version of a transcript of a live lecture given by Grandmaster Milorad Knezevic (FICS handle Knez) on April 15, 1999. 10 k Many extraneous comments were eliminated, and the order in which some comments appear were changed so that they appear right before or after the move(s) being discussed. 15 k For consistency, all moves within kibitzes and whispers were changed to standard algebraic notation. 8 k Spelling errors were fixed. Punctuation and grammar were only fixed when what was being said was difficult to understand otherwise. 12 k Now, on with the show :) k GM Knezevic: hi k GM Knezevic: the main idea of our lecture today is open lines as strategic element 8 k GM Knezevic: experienced players perfectly know the meaning of open lines in chess game 8 k GM Knezevic: in general their main use should be the ways to infiltrate in opponent's camp k GM Knezevic: but apart from the abstract meaning of open line , we must find some moment supporting its use , for example better coordination of pieces , more space and so on 17 k GM Knezevic: I will start showing my game against GM Kypreichic , played in Czechoslovakia 1975 9 bname Kypreichic 1 k GM Knezevic: i have white pieces d4 d5 c4 c6 Nc3 e6 Nf3 Nf6 e3 Nbd7 Qc2 Bd6 e4 k dfgordon(CA): e4 is very aggressive k GM Knezevic: 7.e4 , with idea to open game as much as possible , and also trying to open some central lines , at the same time developing well 30 dxe4 Nxe4 Nxe4 Qxe4 Bb4+ Bd2 Bxd2+ Nxd2 O-O O-O-O k dfgordon(CA): 0-0-0 is interesting k GM Knezevic: For the moment white could be satisfied with opening as he got more space and better development! 30 e5 k GM Knezevic: 12...e5 Black is in danger to be too much cramped , and he started fighting for centre 30 dxe5 Qa5 Bd3 g6 Bb1 k GM Knezevic: 15.Bb1! Solving whites problems and with good prospect to control both central lines 30 Nxe5 Rhe1 f6 k dfgordon(CA): f6 is a sign that things are not going well k GM Knezevic: 16 ...f6 , With idea next move Bf5 15 Qh4 k Alias: Why not Be6 k dfgordon(CA): Be6 loses a piece to f4 15 Qc5 k GM Knezevic: 17...Qc5 Trying some counter play with pressure on c4 pawn.But white is perfectly coordinated and tactical complications are serving to him 15 f4 k GM Knezevic: 18 f4! If now black takes on c4 he is immediately lost! 20 Nxc4 Ne4 k Obliviax: why can't Qe7 be played to avoid Nxf6+? k dfgordon(CA): on Qe7 Nd6 looks strong 15 Qb4 Nxf6+ Kg7 Qxh7+ Kxf6 Qxg6 15 back 8 Ng4 k GM Knezevic: he played Ng4 Re2 k GM Knezevic: Re2! Now you will see the main way of using open line : Occupy it with both rooks , come to 7th or 8th rank and try to finish game in direct attack 16 k GM Knezevic: Of course such things do not happen often , just in the case as here when everything works in our favor! 30 Kg7 Rde1 Rf7 Re8 k GM Knezevic: 21.Re8 , That's it! 12 b5 k GM Knezevic: 21... b5?, mistake , losing immediately , but anyway black position is hopeless 20 Bxg6 k GM Knezevic: Bxg6!! k Obliviax: threats: Qxh7 and Bxf7, or if hxg6 then Qh8++ 20 Kxg6 Rxc8 k GM Knezevic: of course it is not necessary to say after 23...Rxc8 24. Qxg4 and Qxc8 16 Nf2 Rxa8 Nd3+ Kb1 Qf5 g4 Qxf4 Rg8+ k GM Knezevic: 27. Rg8 And black resigned , as after Rg7 he gets mated with Qh5 10 Rg7 Qh5 k GM Knezevic: This was just extreme case where white had all conditions for attack 8 k GM Knezevic: but it is anywhere good to know technique of occupying one of last ranks 8 k GM Knezevic: now we will see another game also about lines and ranks.It is my game against Russian GM Alexander Zaitzev(Not related with GM Igor Zaitzev) 14 k GM Knezevic: Alexander was even champion of USSR , but unfortunately died in the best age. 8 revert 1 bname A.Zaitzev 1 e4 c6 d4 d5 exd5 cxd5 c4 Nf6 Nc3 e6 Nf3 Be7 k GM Knezevic: Panov Botvinik line of Caro Kann 6 cxd5 Nxd5 k Knightnite: what is current theory on isolated pawn, a bonus, or a weakness 8 k GM Knezevic: (about isolated pawn)This is a non stop discussion about this matter and it is not possible to give direct answer 12 Bb5+ k GM Knezevic: almost forgotten move but deserving serious attention.In this line Alekhine won against Eliskases on Olympiad in Buenos Aires 1939 13 Bd7 Bxd7+ Qxd7 Ne5 Nxc3 bxc3 Qd5 O-O Nc6 Re1 k Knightnite: what about b5 any good? k GM Knezevic: black has no time for such moves like b5, he must finish developing 20 Rc8 k dfgordon(CA): not 0-0 yet? hmmm that might cost k GM Knezevic: 13...Rc8 more simple is 13...o-o 15 Bb2 O-O k GM Knezevic: 14...0-0? k GM Knezevic: black ignored the critical moment of all position -- danger to his position from whites Ne5 15 k GM Knezevic: it was the last moment to change that knight taking it with N from c6 15 k Knightnite: is c4 good for white k GM Knezevic: yes k GM Knezevic: it is the next move 10 c4 Qd8 Ng4 k GM Knezevic: 16.Ng4 extremely important move , after that white gets strong attack! k dfgordon(CA): d5 is crushing 25 Na5 c5 Nc6 k GM Knezevic: 17...Nc6 , Black likes to install his N on d5 , afterward he would have clear advantage.But white will not allow it! 18 Re3 k GM Knezevic: 18.Re3! If now 18...Nb4 6 Nb4 Rb3 k GM Knezevic: and b7 pawn is hanging 8 back 2 Qd7 k GM Knezevic: 18...Qd7 Now he likes Nb4, as b7 pawn is protected, but white turns on direct attack on blacks king 15 Rg3 f6 k solochess: was the f6 to let the Q protect the g7 pawn? k dfgordon(CA): yes, and block long diagonal 15 Nh6+ Kh8 Qg4 Bd8 k GM Knezevic: 21... Bd8 for the moment looks black managed with defense, but 10 d5 k GM Knezevic: d5! 15 k GM Knezevic: 22...gxh6 No other moves k Obliviax: Ne5 wasn't possible? k dfgordon(CA): if Ne5 then Bxe5 and dxe6 20 gxh6 k dfgordon(CA): theme of open lines again 12 dxc6 Rxc6 k GM Knezevic: For the moment I almost thought "what have i managed , no attack anymore and he even has a pawn more?" But after that I immediately "recognized" d-line and 7th rank! 18 Rd1 Qf7 Rgd3 Be7 k Knightnite: black is very disorganized Rd7 Rxc5 Ba3 Rg5 Qf3 Re8 Qxb7 Qh5 k GM Knezevic: 29...Qh5 , the last black attempt , in some lines the Rd1 is hanging 15 Bxe7 Rxe7 Rd8+ Re8 Qf3 k dfgordon(CA): !! k Ricci: wow k Psycho: I would love to play such a move in a tourney.... k DAV: Q looks like it's overloaded. 6 k Obliviax: sweetest variation is RxR then Qxf6+ 10 k Knightnite: what if black did qf7? k Obliviax: then RxR+ followed by Qxf6+ and Rd8! 15 k GM Knezevic: Qf3!! And here black resigned , as after 32...Qxf3 8 Qxf3 Rxe8+ Kg7 Rd7+ Kg6 Rg8+ Kf5 Rxg5+ hxg5 gxf3 k GM Knezevic: And white as you see stays with R more 6 k GM Knezevic: it was the most important in using open lines on a direct way.Of course there are many moments with maneuvering and positional playing in different positions , but it is something what needs much experience and practice! 23 k GM Knezevic: That was all for today.Thanks very much for attention! 6
