$ChessTask File $Version: 2.0 Example tasks 6 Introduction 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0 $BEGIN_TASK The following positions were taken from several of my own games for the SK Soltau. They are not supposed to be examples of good chess play. Their purpose here is to demonstrate what ChessTask can do for you. The given solutions might be incomplete or even incorrect. $END_TASK $BEGIN_SOLUTION $END_SOLUTION Game A 0,0,0,0,0,0,0,0,0,0,0,6,0,0,9,0,0,0,0,0,0,0,0,9,0,0,0,0,14,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 1 $BEGIN_TASK In this position Black tried to keep his opponent away from his pawns with \movecomment{46. ..., Kf6?} but this is wrong! After \movecomment{47. Ke8} White holds the draw with \movecomment{47. ..., g5 [47. ..., g6 48. Kf8 h5 49. Kg8 hxg4 50. hxg4 Kg5 51. Kg7 Kxg4 52. Kxg6\equal] 48. Kf8 Kg6 49. Kg8 h5 50. gxh5+ Kxh5 [50. ..., Kh6 51. Kh8] 51. Kg7 Kh4 52. Kg6 Kxh3 53. Kxg5\equal}. Which would have been the correct move that leads to win for Black? $END_TASK $BEGIN_SOLUTION By playing \movecomment{46. ..., Kf4} Black does not lose any time and after \movecomment{47. Ke6 g5 48. Kf6 Kg3 49. Kg6 Kxh3 50. Kxh6 Kxg4 51. Kg6 Kf4 52. Kh5 g4 53. Kh4 Kf3} the pawn promotes very soon. $END_SOLUTION Game B 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9,9,0,0,0,0,0,9,0,14,0,6,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 1 $BEGIN_TASK At first sight this position looks like a draw. The pawns to the right can not move (or at least they should not) and with \movecomment{59. ..., Ka3 60. Kc3 Ka4 61. Kc4} Black does not seem to get any further. How can Black win this game? $END_TASK $BEGIN_SOLUTION \movecomment{59. ..., Ka3 60. Kc3 a4!} and then either \movecomment{61. Kc2 Kb4} or \movecomment{61. Kc4 Kb2}. The black king leaves his a-pawn and while White captures it, Black has enough lead to take both white pawns. $END_SOLUTION Game C 0,0,0,0,0,0,0,0,0,0,0,0,12,0,0,0,9,9,0,9,0,14,0,9,0,0,0,3,0,9,0,0,0,1,1,0,0,1,1,0,1,0,10,0,0,0,0,1,0,0,0,0,4,0,6,0,0,0,0,0,0,0,0,0 1 $BEGIN_TASK Black's last move was \movecomment{40. ..., Ne4-c3} in order to attack the rook and the bishop simultaneously. Because of his better position White captures the rook \movecomment{41. Rxe7 Kxe7}. How could White have played much better? $END_TASK $BEGIN_SOLUTION After \movecomment{41. g5+ hxg5 42. fxg5+ Kxg5 43. Rxe7} White has won a rook for a pawn! $END_SOLUTION Game D 0,0,0,0,0,0,0,0,0,0,0,0,10,0,1,0,0,0,0,0,0,0,0,0,9,0,0,0,14,0,0,0,1,0,3,0,0,0,0,6,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 1 $BEGIN_TASK Black's last move was \movecomment{58. ..., Kf5-e5}. White---after checking that his bishop covers the promotion square of the a-pawn---decides to play \movecomment{59. g8Q Nxg8 60. Bxg8}. He plans to capture the black a-pawn and promote his own a-pawn more or less quickly. Is there a faster win for White? $END_TASK $BEGIN_SOLUTION White should play \movecomment{59. Kg5!}. After \movecomment{59. ..., Kd6 60. Kf6 Kd7 61. Bf7 Kd8 62. Ke6} the black numb has to move---otherwise he is lost---and the white g-pawn promotes. $END_SOLUTION Game E 12,0,0,0,0,0,14,0,0,0,0,0,0,9,9,0,0,0,13,0,9,0,0,9,9,0,0,10,2,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,1,0,1,0,4,5,1,6,0,0,0,0,0,0,0,0,0 1 $BEGIN_TASK Here, Black and White have only seconds left for their 40th move. So both do not realize that White's last move \movecomment{40. Nf3-e5} is a blunder. Black quickly moves his threatened queen \movecomment{40. ..., Qd6}. How could he have ended the game in two moves instead? $END_TASK $BEGIN_SOLUTION After \movecomment{40. ..., Nf4+} or \movecomment{40. ..., Ne3+} White can try \movecomment{41. Kh2} or \movecomment{41. Kg1}. Both times, Black checkmates with \movecomment{41. ..., Qg2\mate}. If White tries to escape with \movecomment{41. Kf1} then \movecomment{41. ..., Qh1\mate} follows. $END_SOLUTION
