White will eventually have to advance his kingside pawns and every. tempo could prove decisive This is why it makes sense to start active. operations there as soon as possible The standard plan in such positions. would be 45 f3 followed by 46 g4, 45 a5 46 Ra7, The obvious 46 Ra6 Kd5 leads to a position from the game Akopian. Kir Georgiev Las Vegas Wch 1999 with colors reversed Diagram 9. 166 in the Endgame Manual The complicated analysis given in the book. shows that White s counterplay comes too late so his position is lost. 46 a4 47 Ra5, How many times can White make the same double blunder Again he. takes his rook off the seventh rank and postpones his kingside. counterplay After 47 f3 it appears that the position would still have. been drawn, The advance of the black king sacrificing the f7 pawn is very. dangerous for White either with the rook on a3 and White s king on. g2 as in the above cited endgame Akopian Georgiev or with the. rook on a2 and the pawn on a3 Ernesto decided to play the second of. these lines Objectively speaking 47 Kd6 was stronger and should. The concluding error although a most excusable one According to prior. theory the text move assures White an easy draw Only recently was it. discovered that White s only chance to save himself is 49 g4 You may. find out all the rest in the detailed analysis of the Kantorovich Steckner. position from my Endgame Manual Diagram 9 144, 49 Kd5 50 Ke3. The main line is 50 Rxf7 Rc2 51 Ra7 a2 52 Kf4, The Swiss player Johannes Steckner discovered that after 52 Kc5.
Black wins by a single tempo For example 53 Kg5 Kb6 54 Ra3 Rc5. 55 Kxg6 Ra5 56 Rxa2 Rxa2 57 Kxh5 Kc6, 50 Kc4 51 Rxf7 Rc2 52 Rc7 Kb3 53 Rb7 Kc3 54 Ra7 a2 55 f3 Kb3. 56 Rb7 Ka3 57 Ra7 Kb2 58 Rb7 Kc1 59 Ra7 Kb1 0 1, Sometimes the stronger side is able to place his rook on the same. rank as his passed pawn in order to defend both it and his pawns on. the other wing Such a setup is exceptionally dangerous for the. defender since the king is then free to jump over and support its. passed pawn, Let s examine an instructive endgame badly played by Adrian. Mikhalchishin and poorly annotated by him in his book Modern. Endgame Practice Some considerably deeper and more accurate notes. were given by Boris Gelfand first in Informant 80 and later in his book. My Most Memorable Games I shall rely on these, Gelfand Mikhalchishin. Istanbul Ol 2000, White s rook cannot guarantee the protection of his kingside pawns so.
one might suppose that the position is drawn The guiding principle in. defending such situations is generate counterplay on the kingside. after White s king has gone to the queenside Well such general advice. is easily given It is much harder to choose the only correct concrete way. to do it Let s examine the different possibilities. A 54 Kh7 The passive defence I rejected White will sacrifice the g4. pawn to control the a pawn with his king It is too late for Black s. counterplay g7 g6 Mikhalchishin, This note makes no sense he does not explain under exactly what. circumstances White would be justified in sacrificing the g4 pawn for. nothing when in fact it should not be given up at all Since. Mikhalchishin s analysis stops here while Gelfand did not examine. moving his king to h7 I had to study it for myself The results were pretty. interesting, 55 Ke3 Rxg4 56 a6 56 Kd3 Ra4 57 Kc3 g6 56 Ra4 57 Rb6 Ra5. or 55 g5 hg 56 Rxg5 Kh6 57 Kc5 g6 are useless, It is more logical for White to play for zugzwang 55 Rc5 Now 55 g6. leads to a position that we will examine later on cf 54 g6 Here we. shall test a continuation of Black s waiting tactics by 55 Kg8 and the. move 55 g5, A1 55 g5 56 Rc7 Kg8 57 Ra7, Black cannot just jog in place White would continue 58 a6 and send his. king after the a pawn 57 Rf4 58 Kg3 Re4 might look tempting with. the idea 59 a6 Re6 60 Kf3 Kh8 when Black has a guaranteed draw. because his rook simultaneously locks White s king up on the kingside. while tying White s rook to the pawn s defense However White has the. winning 59 Ra6 allowing the rook to get off the a file and move the. pawn up to a6 For example 59 Kh7 60 Rb6 Ra4 61 a6 Kg7 62 Rb7. Kf6 63 Rh7 Ra3 64 Kf2 Ke5 65 Rxh6, We must also check 57 Kf8 58 a6 Ke8 59 Ke3 59 Ra8 Kf7 60 Ke3.
Kg7 would be premature with his next move Black intends to snap. off the g4 pawn 59 Kd8 60 Ra8 Kc7 60 Ke7 61 a7 Kf7 62 Rh8. After Black s king moves to the queenside White should plan on. securing the g4 pawn with his king 61 Kf3 wins for example 61 Rf4. 62 Kg3 Rf6 63 a7 Kb7 64 Rg8 Kxa7 65 Rg6, An instructive draw occurs after the mistaken 61 Kd3 Rxg4 62 Rh8 Kb6. 63 Rxh6 Ka7, After 64 Rg6 Rh4 65 h6 65 Rxg5 Kxa6 65 Ka8 the white king. permanently cut off on the fourth rank cannot get close to its pawns and. without its help they can never queen, But if White leaves the rook at h6 then a position of mutual zugzwang. inevitably arises with the rook on h4 and the king on g3 and White. cannot obtain this position with Black to move For example 64 Ke3 Rh4. 65 Kf3 Rf4 66 Kg2 Rg4 but not 66 Rh4 67 Kg3 zugzwang 67. Kh3 Rf4 68 Kg3 Rh4 zugzwang, Once again the pawn sacrifice does not work 56 Ke3 Rxg4 57 a6 Ra4. 58 Rc6 Kf7 59 Kd3 Ke7 60 Kc3 Kd7 61 Rg6 Kc8 62 Kb3 Ra5 and. draws Therefore White continues 56 Rc8, After 56 Kh7 57 Ra8 the attempt to attack the a pawn from the flank by.
57 Rc4 58 a6 Rc6 generally speaking this is a typical method of. defense against a rook pawn fails to achieve its aim in view of the rook s. inability to operate freely on the f file without the important square f5. and on the e file it is too close to the pawn, Here s a sample variation 59 Ke4 Rb6 60 Kd5 Rf6 61 Kc5 threatening. 62 Kb5 61 Re6 62 Kb5 Re5 63 Kc6 Re6 64 Kc7, And if 56 Kf7 then 57 Ra8 Kf6 58 Ra6 Kf7 no longer works. White plays 57 Rc7 Kf6 57 Kg8 58 Ra7 58 Rc6 instead with 59. a6 to follow reaching the same winning position as in the game We shall. analyze that later on, B At first Gelfand thought that Black could draw by playing 54 g6. but while preparing his book for publication he found the winning. method for White, 55 hg Kg7 56 Kg3 Kxg6 57 Kh4 Ra1 58 Rb6 Kg7 59 Ra6 Rh1 60. Kg3 h5 is not a problem, After 55 Ke3 gh but not 55 Rxg4 56 Rb8 Kg7 57 Rb7 Kf6 58 Rb6.
Ke5 59 Rxg6 56 gh Kf7 57 Kd3 Ke6 58 Kc3 58 Rb6 Kf5 58. Kd6 59 Kb3 Ra1 the a pawn is no longer a threat White will have to. trade it for the pawn at h6 The game might continue as follows 60 Kb4. 60 Rb6 Kc5 61 Ra6 Kb5 62 Rxh6 Rxa5 63 Rh8 Kb6 64 h6 Kb7 65 Kc4. Ra6 changes nothing 60 Rb1 61 Kc4 Rc1 but not 61 Ra1 62. Rb6 Kc7 63 Kb5 62 Kd4 Ra1 63 Rb6 Kc7 64 Rxh6 Rxa5 65 Rh8. Kb7 66 h6 Ra6, On the board we have the so called Vancura Position which every. chessplayer will find useful to include in his briefcase of endgame. knowledge The rook attacks the pawn from the side keeping the. opposing rook tied to the h file and checking the king away from the. pawn when it goes to the kingside, 55 Rb8 Kg7 56 Rb7 is considerably stronger The king cannot move. forward and remain cut off on the eighth rank Let us examine 56 Kg8. 57 Ra7 gh 58 gh Kf8 59 a6 Ke8, As in the similar situation from the 54 Kg8 variation where the pawns. at g4 and g5 were still on the board the major subtlety of the position is. that White must give check with the rook at a8 at exactly the right. moment not to early nor too late, B1 The immediate 60 Ra8 leads to a draw 60 Kf7 61 Ke3 Kg7. just not 61 Kf6 62 Rg8 62 Kd3 Ra5 63 Kc4 Rxh5 64 Kb4 64 Rc8. Ra5 65 Rc6 h5 66 Kb4 Ra1 67 Kb5 h4 64 Rh1 65 Rc8 Ra1 66 Kb5. A standard technique to avoid interference the king is checked into a less. favorable position 66 h5 loses to 67 Rc5 Kg6 68 Kb6. 67 Kc6 Ra1 68 Kb7 Rb1 69 Ka8 Kg6, B2 60 Ke3 Kd8, Waiting tactics do not make much sense here 60 Kf8 61 Kd3 Ke8 and.
White does not play 62 Kc3 Kd8 63 Kb3 Ra1 64 Kc4 Kc8 65 Ra8 Kc7. 66 a7 Kb7 but 62 Ra8 Wherever the king goes White wins easily. 62 Kf7 63 Kc3 Kg7 64 Kb3 Ra1 65 Kb4 or 62 Kd7 63 a7 Kc7 64. Rh8 Rxa7 65 Rh7 Kb6 66 Rxa7 Kxa7 67 Ke4, The rook check must be given now since 61 Kd3 Kc8 62 Kc3 Ra5 leads. only to a draw As in the analogous situation from the 54 Kh7 variation. after the black king arrives on the queen s wing White changes his plan. and sends his own king after the pawns on the opposite side. 61 Ra8 Kc7 61 Ke7 62 a7 Kf7 63 Rh8 62 Kf3 Ra5 62 Rh4 63. Rh8 Kb6 64 Rxh6 62 Kb6 63 Rh8 Kxa6 64 Ra8 63 Kg4 Rg5 64. Kh4 Ra5 65 a7 Kb7 66 Rh8 Ra4 67 Kg3 Kxa7 68 Rxh6 Ra5 68 Kb7. If the black rook were on c5 we would have the drawn Vancura position. We would inevitably arrive at the same situation if the white king stood a. little farther away from the pawn But here it stands ready to support the. pawn and it cannot be driven away by checks since the black king. interferes with its own rook Here s a sample line 69 Rh7 Ka8 70 Kg4. 70 h6 Ra6 71 Kg4 Rc6 70 Ra4 71 Kg5 Ra5 72 Kg6 Ra6 73. Kf7 Ra7 74 Kg8 Ra5 75 h6 Ra6 76 Rh8 Ra7 White threatened 77 Kg7. discovered check 77 Kf8 as 78 Rg8 is coming next, For a full picture recall that at the very beginning of this variation the. black king could have immediately gone over to the queenside 56 Kf8. instead of 56 Kg8 57 Ra7 gh 58 gh Ke8 59 a6 Kd8 But this would. have changed little 60 Ra8 Kc7 61 a7 61 Kg3 would be a mistake. 61 Ra5 62 a7 Kb7 63 Rh8 Kxa7 64 Rxh6 Rc5 this is the Vancura. position 61 Kb7 62 Rh8 Kxa7 63 Rxh6, We already know what happens after 63 Ra5 64 Rh7 and 65 Kg4 And. 63 Kb7 should be answered not by 64 Rg6 Rh4 65 h6 Kc7 66 Kg3. Rh1 nor by 64 Rh8 Rc4 intending 65 Rc5 but by 64 Rh7 Kc6. 64 Kb8 65 Kg3 Ra5 66 Kg4 65 h6 Rh4 Black can no longer attack. the pawn from the side and the rook behind the pawn is known to be lost. for Black 66 Rh8, C Mikhalchishin rightly considers 54 g5 to be the correct move here. He examined the variation 55 Rb6 55 Rb8 Kf7 56 Ra8 Kf6 57 a6 Kg7. or 56 Rb7 Kf6 57 Rb6 Ke5 58 a6 Ra3 59 Ke2 Kf4 60 Rxh6 Kxg4. 61 Kd2 Kh4 Gelfand 55 Rxa5 56 Rxh6 Kf7 57 Rd6, It seemed to me that after a subsequent march of the king and the move.
Rd6 d5 the endgame could not be held but I did not notice that Black. keeps the rook on e5 and makes a draw this also shows poor knowledge. of a theoretical position Mikhalchishin Well let s just say that poor. knowledge of theoretical positions does not mean much here since the. position is not a theoretical one What we should be talking about here is. a theoretical technique cutting off the king In fact 57 Re5 gives. Black an uncomplicated draw 58 Rg6 Ke7 59 h6 Kf7 60 h7 60 Rg7. Kf6 60 Re8 61 Rxg5 Rh8 62 Rh5 Kg7 63 Kf4 Rf8 and White cannot. make progress, On the other hand it is not clear how he was going to win after 57 Ke7. 58 Rd4 Kf6 59 Ke4 is met by 59 Re5 either, As you may see the only correct path turned out not to be so complex. after all Now the refutation of the alternative possibilities required a. great deal of hard analysis but that way you do not have to do it during. D Black s mistaken choice of 54 Kf7 in the actual game which. Mikhalchishin awarded a would only have justified itself if White. had played 55 g5 hg 56 Rxg5 Kf6 57 Rb5 g6 or 57 g5 as long as. Black does not play 57 Ke6 58 Ke3 Kd6 59 Kd3 Kc6 60 Rg5 and 61. Rg6 when White wins 58 h6 58 Rb6 Kg5 58 Rh4 59 a6 Rxh6. 60 Ra5 60 a7 Rh3 60 Rh8 61 a7 Ra8, 55 Rb7 Kf6 55 Kg8 56 Ra7 is no fun for Black either 56 Rb6 Ke5. This is the ideal layout of White s forces that we spoke of when we. introduced this example The rook defends the passed pawn from the side. while simultaneously protecting from g6 his own kingside Such. situations are won as a rule marching the king over to the passed pawn is. decisive And if Black s king comes and stands in the way then the. king s wing will be left undefended, 57 Ra3 58 Ke2 Kd4 59 Rd6 Ke4 60 Kd2 Ke5 61 Rg6 Ke5 62 Kc2. On 62 Rxg7 Rxa6 63 Rg6 Mikhalchishin gives 63 Ra4 although of. course 63 Rxg6 64 hg Ke6 would do equally well, 62 Ra4 63 g5 hg 64 Rxg5 Kc6 65 Rxg7 loses at once.
Mikhalchishin but the text move was no better There followed 63 Kb2. Ra5 64 Rxg7 Rxa6 65 Rg6 Ra4 66 Rxh6 Kd5 67 Rg6 and Black. He could have held out far longer after 62 Kc5 The grandmaster. believes Black could have saved the game He gives the line 63 Rxg7. Rxa6 64 Rg6 Rd6 65 Kc3 65 g5 Rd5 65 Rd4 all exclamation. marks are Mikhalchishin s, But in fact as the following analysis will make clear the final position of. his variation is lost However Black can in fact save himself by 64 Ra4. instead of 64 Rd6 65 Kd3 Kd5 66 Ke3 Ke5 67 Kf3 Ra3 67 Rf4. 68 Kg3 Rf6 is not bad either 68 Kg2 Kf4, And yet as Gelfand demonstrated 62 Kc5 would not have saved Black. Before capturing on g7 White would need to improve his king s position. and take away the a4 square from Black s rook This can be done by 63. Kb2 Ra4 64 Kb3 Ra1 and only now playing 65 Rxg7 Rxa6 66 Rg6 Rd6. here indeed Black has nothing better, 67 Kc3 of course not 67 Rxd6 Kxd6 68 g5 Ke6 69 g6 Kf6 67 Rd4. 67 Kd5 68 g5 68 g5 Mikhalchishin only looks at 68 Rc6 Kxc6. 69 Kxd4 Kd6 68 Rd5 69 Ra6 Kb5 69 Rxg5 70 Ra5 Kd6 71 Rxg5. 70 Rxh6 Rxg5, 71 Kd4 71 Rh8 Kc6 72 h6 Kb7 lets slip the win 71 Ka5 72 Ke4. Getting the king closer to the pawn is important The hasty 72 Rh8. would be a mistake 72 Kb6 73 h6 Kb7 threatening 74 Rg6 with the. Vancura Position 74 Rf8 Rh5 75 Rf6 and Black s king gets back to. the kingside in time 75 Kc7 76 Ke4 76 Ra6 Kb7 76 Kd7 77 Kf4. 72 Rb5 73 Rh8 Rb4 73 Ka6 74 h6 Rb4 75 Kd5 Rb5 76 Kc4 Rh5.
