   zb2cr has kibitzed 2800 times to chessgames   [more...]
   Jul-07-20 Huebner vs Adorjan, 1980
zb2cr: Had to be a stalemate trap, and the most obvious is 66. Kxh4. If Black takes the Rook, White is stalemated. What about other moves for Black's 66th? 66. ... Rc4+; 67. Rg4, Rc5; 68. Rb4 looks drawish. 66. ... Rc3; 67. Rg4, Rb3; 68. Ra4, Rxb5; 69. Rxa7, Rb1 is more unbalanced but I ...
   Jul-06-20 Denker vs D MacMurray, 1932 (replies)
zb2cr: Why sacrifice a Queen, when a Rook will do? Besides, 14. Rd8+ is more forcing, since Black can't play anything but 14. ... Nxd8, which allows 15. Qe8#. 14. Qxc6, Qxg5+; 15. e3, bxc6 doesn't look like a win for White, <et1>.
   Jun-29-20 R Kiuttu vs A Giri, 2005 (replies)
zb2cr: 15. ... Rxg7 works. Black is threatening ... Bxg2#. White's most easily visible defense, 16. Qxe2, Rxg2; 17. Qe4, is refuted by 17. ... Qc7!. After 18. Kxg2, Bze4+; 19. Nxe4, qc6; 20. Rae1, f5 wins the Knight and Blakc has a good material edge. <abg2002> has done excellent work ...
   Jun-22-20 E Pettersson vs Stahlberg, 1935 (replies)
zb2cr: 34. ... Rb1+ does the trick. If White plays 35. Kxb1, Nxc3+ regains the Rook , leaving Black ahead by 3 Pawns. If White declines by 35. Ka3, he ends up in even worse case after 35. ... Rb3+; 36. Ka2, Nxc3+; 37. Ka1, Rb1#. 35. Ka2 is simply fatuous, as Black gets to mate in two by 35.
   Jun-15-20 B Rabar vs E Paoli, 1953 (replies)
zb2cr: 33. ... Nf3+. No matter what White does, the next move is 34. ... Qxh2#. Except in the case of 34. Kh1, when Black has the choice of playing 34. ... Rxh2#, for an Arabian mate.
   Jun-08-20 D Byrne vs W G Addison, 1969 (replies)
zb2cr: White ends up with a 2 Pawn advantage after 27. Rxc6, bxc6; 28. Nxc6+ regaining his sacrificed Rook.
   Jun-02-20 I Cheparinov vs S Nikolov, 2005 (replies)
zb2cr: Nice analysis, <agb2002>.
   Jun-01-20 M Mrva vs Movsesian, 1997 (replies)
zb2cr: With the Black Queen pinning the White Rook, 32. ... Rxf1+ gives mate in 4, 33. Kxf1, Bd3+. Now White has two ways to lose, neither of them elegant: A. 34. Kg1, Qe1+; 35. Rf1, Qxf1#. B. 34. Re2, Qxe2+; 35. Kg1, Qf1(e1)#.
   May-26-20 Mamedyarov vs A Tasan, 2002 (replies)
zb2cr: : Not entirely sure I agree with "easy". Looks like White's best try is 42. Rc7+. Now, Black can refuse the sacrifice in two ways: A. 42. ... Kh8; 43. Qh6+ with mate next move. B. 42. ... Kg8; 43. Re8+, Bf8; 44. Rg7+, Kh8; 45. Rxf8#. So much for declining the sacrifice. What about ...
   May-25-20 A Chibukhchian vs Z Izoria, 2001 (replies)
zb2cr: Black gets a winning edge in material with 32. ... Qxg1+; 33. Kxg1, Ne2+; 34. Kh2, Nxg3; 35. Kxg3, Rxg2+ and Black is up by the exchange and a Pawn.
