| Sep-03-07 | | Dr. Siggy: Dr. Tarrasch, "The Game of Chess", english transl., London 1934, pages 50-2: "For a player defending against a pawn on the fifth or even on the sixth rank to obtain a draw, even after his King has been forced off the queening square, the following conditions must obtain: The file on which the pawn stands divides the board into two unequal parts. The defending Rook must stand in the LARGER part and must give checks from the flank at the greatest possible distance from the attacking King. Nothing less than a distance of three files makes it possible for the Rook to keep on giving check, otherwise it would ultimately be attacked by the King. The defending King must stand in the SMALLER part." After 77... Ra2!, White could not win since the Black Rook, when giving checks from the flank (...Ra6+, etc.), was three files removed from the White King, which could not, therefore, successfully approach it. "From these demonstrations [...] we see that the Knight's pawn always wins in these circumstances since there is no room for the defending King in the smaller part of the board [...]." |

click for larger view <38... 1c3+>? When the game finished, <"Meister Schottländer"> showed how 8c3+! would win: 39.h4 h7!! with some <"problemartige Wendungen"> for instance if 40. e6 e1+ 41.h5 g3!!

 | | Chessical: <vonKrolock>: Rybka and Fritz both support Schottländer's penetrating anlysis. <38...R8c3+!> 39. Kh4 Kh7 40. Qe6 Qe1+ 41. Kh5 Rc6 42. Qf7 Qg3! 43. hxg3 Rh1 mate. Despite using a favourite system, Tarrasch got no advantage from the opening against an opponent who was very proficient with the French defence. I do not know the round order, but the game at move 15 is identical with the famous Tarrasch vs Spielmann, 1906 also at the 1906 Congress. 
click for larger view There Tarrasch took the Knight on <c5> and soon ran into grave problems, so it seems logical that <15.0-0-0> was an improvement and Tarrasch still had faith in the variation. In this game, Tarrasch's woes appear to stem from allowing Swiderski's Queen to penetrate to <f1>, so <36. Kf2> is indicted with R(4)d3 preferred |
