   Aug-30-14 Tarrasch vs Schlechter, 1911 (replies)
Dr. Siggy: According to Dr. Tarrasch, after 44. ... ♖xg3, "White's King comes up to the Queen's Bishop pawn via e4 and conducts it on to queen." I may be wrong but, after 44. ... ♖xg3 45. ♔e4 ♖c3 46. c5 a3 47. ♔d5, Black's game seems as good as lost...
   Nov-30-12 Ruy Lopez, Open (C83) (replies)
Dr. Siggy: A demonstration of how to play against the Breslau variation of the Ruy Lopez, with a very beautiful finish: NN vs Tarrasch, 1915 .
   Aug-30-12 Tarrasch vs Schlechter, 1911
Dr. Siggy: <master of defence>: After 15...exf4 16. Qxf4, Black's castling becomes too vulnerable, namely at f7 and h7. For instance: (1) 16...Qd7 17. Qh5 h6 18. Nxf7; (2) 16... Qd5 17. b4 Bb6 18. Bxb6 cxb6 19. N or Qxf7; (3) 16...Qf6 17. Qxf6 gxf6 18. Ne4 Kg7 19. Rf3 followed by Raf1.
   Apr-20-12 Alekhine vs E Andersen, 1933 (replies)
Dr. Siggy: Here's the position after 21... Nxc8: [DIAGRAM] From Reuben Fine, "Basic Chess Endings", New York 1941, pages 111-2: "Unlike a Bishop a Knight is at home in any Pawn structure, so that advantages of this type must be utilized immediately or they will dissipate into thin air. The ...
   Apr-09-12 Spassky vs Chandler, 1987
Dr. Siggy: After 11... Nd5, it would be interesting to know why Spassky didn't play the very promising exchange sacrifice 12. Nxd5 exd5 13. Bxd5 Bh3 14. exd6! Bxf1 15. Kxf1! which would have left Chandler in serious trouble...
   Apr-07-12 Lilienthal vs Botvinnik, 1944 (replies)
Dr. Siggy: A closer examination of this game reveals that, from the very start, Botvinnik was completely outplayed by Lilienthal. What is more, after 39. Rc3 Botvinnik's position was as good as lost. The only reason why Lilienthal answered 39... e4 with the lamentable 40. fxe4 (instead of ...
   Apr-01-12 Paulsen vs Tarrasch, 1888 (replies)
Dr. Siggy: <bystander>: After 19. Kg2, Black would play 19... Qa6 and double his Rooks on the c-file with a strategically won game. Instead of 28... h6, Tarrasch himself would later recommend 28... Ra2, winning the a-pawn without danger as White's Rook couldn't break in along either ...
   Mar-31-12 Ljubojevic vs Portisch, 1982 (replies)
Dr. Siggy: Here's the position after White's 96th move: [DIAGRAM] Portisch draws this <♖ + ♗ vs ♖ endgame> using the so-called Cochrane Defense: 96... ♖e1! The <Cochrane Defense> works when (1) the defending Rook pins the Bishop to the King on one of the ...
   Mar-16-12 Piket vs J Arnason, 1990
Dr. Siggy: What a pity!... Piket emerges from a rather difficult opening with a very well earned advantage just to throw it away at the beginning of the middle game with 22. fxe6? fxe6 23. c5? (instead of increasing it with the beautiful 22. Nxe6! fxe6 23. f6!) and 26. Qh3?? (instead of ...
   Mar-06-12 B Verlinsky vs Lasker, 1925 (replies)
Dr. Siggy: Bogoljubov's note to Black's 6th move is mistaken. The "remarkable novelty" Nb8-a6-b4 was conceived and introduced in practice by Georges Maréchal.
