| Mar-07-15 | | Albanius: 58 Rb8+ wins immediately. |
|
| Aug-06-15 | | bougre: 57. Kxh2 would end the game... |
|
| Mar-23-20 | | Cheapo by the Dozen: This was Tuesdayish in difficulty for me. I tried and failed to get something done with b6, but the problem was that Black had forcing counterplay. So I almost settled for just winning a piece ... but then I did see the Qh5+/Re8++ maneuver. |
|
| Mar-23-20 | | lentil: I saw 58 Rxb8+ almost immediately, but then rejected it because I 'saw' that after Kxb8+ 59 Qd8+ and Qa5+, the R/e1 would check on f8 (?!). (I eventually noticed my mistake!) |
|
| Mar-23-20 | | landshark: After a day of mostly losses at blitz I went for b6, not taking enough time to look at the <entire> board, missing ... Rh1+ which admittedly is desperate and doesn't salvage Black's game. However.... an inferior line is - inferior. No meal for this shark today - |
|
| Mar-23-20 | | boringplayer: I got this one. TY Monday! |
|
| Mar-23-20 | | stacase: This was not yer basic Monday puzzle. At every turn there were several ways to say check and not all of them worked. In the end the obvious moves were the correct ones, but you had to check it out all the way to mate. The continuation of 64...Ka8 is forced allowing the White Queen to say check 65.Qa5+. At this point, you have to notice that she covers a7 and c7 forcing Black's King to move 65...b8 Where White's Rook, not the Queen, says 66.e7# |

 | | al wazir: I saw the win of the piece with 63. Rxb8+ Kxb8 64. Qg8+, and said to myself, "There must be something more elegant." So my move was 63. b6.
A) 63...Qxc8 64. Qa5+ Ba7 65. Qxa7#.
B) 63...Qb4 64. Rxb8+ Kxb8 65. Qd8#.
C) 63...Qc3 64. Rxb8+ Kxb8 65. Re8+ Qc8
66. Qd6+ Ka8 67. Rxc8#.
D) 63. b6 Rh1+ 64. Qxh1 Qxf8 65. Qd5 Qb4 66. Re8 Qc3 67. Rc8, and now proceed as in A) or B). |
|
| Mar-23-20 | | Walter Glattke: 63.Ree8 Qc1(a1)+ 64.Re1 65.Qc3! In the match, then 64.-Ka7 65.Qa5+ Kb8 66.Re8# D2) 63.b6 Rh1+ 64.Qxh1 Qe3+ 65.Kg2 Qd5+ 66.f3!? (others possible) Qd2+ 67.Kh3 Qh6+ 68.Kg2 Qxf8 wins, but by decisive material. |
|
| Mar-23-20 | | saturn2: If 63. Rxb8+ Ka7 it is a rook more but
I did not see an imnediate mate
64. Rbe8 Rh1+ 65. Ke2 Qb2+ 66. Qd |

 | | scormus: It's easy if you're just looking for a clear win, 63 Rxb8 does the job. But it is more interesting to go on and try to find a direct mate after ... Ka7, or by choosing 63 b6 instead. |
|
| Mar-23-20 | | Morten: 63.-, Ka7. 64. Qd4+ and either 64.-, b6. 65. Qxb6++ or 64.-, Kxb8. 65. Qd8+ transposing to the game? But white kept the mouse alive to play with it for too long. |
|
| Mar-23-20 | | agb2002: White has a rook for a bishop.
Black threatens Qf8.
White forces mate with 63.Rxb8+:
A) 63... Kxb8 64.Qd8+ Ka7 65.Qa5+ Kb8 66.Re8#.
B) 63... Ka7 64.Qd4+ Kxb8 (64... b6 65.Qxb6#; 64... Qc5 65.Qxc5+ Kxb8 66.Re8#) 65.Qd8+ transposes to A. |

 | | ajk68: I saw the whole line to mate but I thought there must have something quicker I was missing - it being a Monday puzzle |
|
| Mar-23-20 | | Walter Glattke: 63.-Ka7 64.b6+ Ka6 65.Ra8+ Kxb6 66.Rb1+ Qb3 decisive material, but no immendiate mate so far. |
|
| Mar-23-20 | | Damenlaeuferbauer: After long pondering, the great Russian chess player Evgeni Vasiukov finally found the mate in 4 moves with 63.Rxb8+!,Kxb8 64.Qd8+,Ka7 65.Qa5+,Kb8 66.Re8#. His best game was, in my opinion, against Loek van Wely at the Aeroflot Open 2002 in Moscow, which was awarded for the prize for the best half-year game by the Belgrade/Serbian Informator. As far as I know, in the 1970s and 1980s Shenya worked for Tolya Karpov. |
|
| Mar-23-20 | | zb2cr: Once I discarded the idea of using an immediate Pawn push to b6, I found the forced mate. (A) Main line, Black accepts the sacrifice: 63. Rb8+, Kxb8; 64. Qd8+, Ka7; 65. Qa5+, Kb8; 66. Re8#. (B) Black declines the sacrifice: 63. Rxb8+, Ka7; 64. Qd4+. Now Black has
three choices.
(B.1) 64. ... b6: 65. Qxb6#.
(B.2) 64. ... Qc5; 65. Qxc5+, Kxb8; 66. Re8#. (B.3) 64. ... Kxb8; 65. Qd8+ transposes to line A. |
|
| Mar-23-20 | | lajube: How did Bronstein miss this? |
|
| Mar-23-20 | | TheaN: White mates after <63.Rxb8+>. The 'easy' line is 63....Kxb8 64.Qd8+ Ka7 65.Qa5+ Kb8 66.Re8#. After 63....Ka7 I went slightly suboptimal with 64.Ra8+ #4 (Qd4+ #3); now Kxa8 is 'best' with the same pattern, 64....Kb6 65.Re6+ Qd6 66.Rxd6+ Kc7 67.b6#. |
|
| Mar-23-20 | | stacase: <zb2cr: Once I discarded the idea of using an immediate Pawn push to b6,> Yeah, I kept looking at that, but in the final analysis, all the moves had to say check, otherwise Black was going to unleash the hounds of hell. |

 | | chrisowen: Mob handed absolutely! |
|
Mar-23-20
| | chrisowen: Lord knows wash off? |
|
Mar-23-20
 | | Breunor: I started with b6 but I thought it was too open; I found the mate in 3 but it took me a few minutes. |
|
| Mar-23-20 | | Olsonist: I prefer b6 but I grant the game played is a series of forced checks ending mate. |
|

 | | fm avari viraf: The sweet memories of playing with GM Vasiukov & GM Bronstein still linger in my mind. Both are just wonderful human beings. |
