(see solutions below)


Problem #1: (38. … Rch2  39. f5+ Kg5  40. Rf2 R8h3#), note: in the actual game black chose 38. … Rhh2? and the game continued 39. Rf1 Rhg2 40. Kf3 etc. 1/2 – 1/2

Problem #2: (1. Re7! Re7 2. Rxf6 – threatens both 3. Rf8 mate and 3. Rxc6)

Problem #3: after 18. c4?? black should reply … Bf2! and win a piece (note: the continuation 19. Kf2?? only makes it worse after de and 19. Be4  Re4, which snags the other bishop due to the Queen’s pin on the king).

Problem #4: White has just played 26. Be3 to block the revealed check (after the black Knight moved from f2 with 25. Ne4).  In the game, black played 26. … Be3+, missing the following tactic – 26. … Nd2!  27. Qc1 Nf3+, winning the other Rook.  After this black can follow with Be3+, further reducing white’s material.

Problem #5: The best continuation for black is 35. … f3!, (threatening Nf6 which wins the bishop).  The best continuation for white is … 36. c4 bc 37. bc Nf4 38. Bf3 Nf3 39. Ke3 Nh3 40. Kf3 but black will have solidified his advantage.  In the actual game, black missed this opportunity and chose 35. … h3

Problem #6: The missed shot was 49. … f3! which forces off a piece.  A possible continuation would be 50. Nf2 ef 51. Bh3 Nf5 etc.  The full line is noted in the analysis of Pedersen-Kushner noted above.

Problem #7: Black overlooked mate in 1, and has just queened a pawn.  The finish is 51. c3 # (note: black could have remained even by underpromoting and choosing a Knight)

Problem #8: (note: this problem is setup from the black point of view) White had less then 3 minutes on his clock and had just played Qg4 to try and break the pin.  The reply Ne3!, capturing the Knight and offering the queen, ends the game because black’s checkmate threat can only be stopped by a sacrifice of material by white.

Problem #9: Black has just pushed a pawn to drive the Knight away, but missed the surprising reply – Nc6!  Black played … bc (pawn takes Knight), and was crushed by the x-ray attack Rd7.  All he could do at this point was resign.

Problem #10: In a drawish endgame, black played Kh5 in an effort to eliminate one of white’s pawns.  Unfortunately, he has also trapped his king and after Ne6, it’s mate in 1 – on either Ng7 or Nf4.

Problem #11: White has just retreated his rook from f4 to f1.  Black forced the win after:  25. … g4 26. Rd4  Rh3+  27. Kg2?? e3+  28. Kg1 Rh1 mate (note: it’s still mate even if white chose 27. Kg1, because e4 28. Rf3 Bf3 29. Ke1 Re1).

Problem #12: White has just played 31. Qe1. Black replied Qe4, threatening mate on c2 and winning material. Note that Kb3 doesn’t work as mate occurs after Qc4.

Problem #13: Black played 40. …Kg5 and white missed the game winner, blundering with Rc6?? The correct move was 41. f4!+ forcing the king to h5. After 42. Bf3+ Ng4 (forced), the Rook will fall.

Problem #14: White played 49. hg?? and the game was soon lost after … 50. Kf3 h4 51. gh gh 52. Kg4 Ke4.  Amazingly, the very move that led to black’s victory should have resulted in his downfall. The winning path was 49. g4!! followed by … gh 50. gh h3 51. Kf2 f5 52. Kg3 f4 53. Kh3 after which white will Queen. Note that 49. … hg is no better because … 50. h5 Kf5 51. c4! bc 52. bc Ke6 53. h6 Kf7 54. c5 Kg6 55. c6 and black cannot stop the two white passers.
