| Mar-10-13 | | mistreaver: Sunday. Black to play. Insane.27.?
White is threatening mate in one, but there is option of diverting the rook on h2,
so i would assume that black's combination is not forced as it looks.
At first sight i considered two natural candidates, Rxb2 and Nc3+.
A)
27... Nc3+
28 Kc1 (not Ka1 Ra4+ and black wins)
28... Nxd1+
29 Kxd1 and black doesn't have a plausible check, and can resign.
B)
27...Rxg2+
Now white has two choices:
A1)
28 Kxg2 Rb8+ (not Qb4+ Qb3 and black has nothing); and now:
A12)
29 Ka1 is the move that refutes black's combination as there is not a single check, and queen also covers a3 square.
After assuring myself that both my lines are big fails, i considered synthesis of both ideas.
C)
27... Nc3+
28 Kc1 Nd4+
29 Kb1 and black has a draw
D)
27... Nc3+
28 Kc2 Rxb2+
29 Kxb2 Qb4+
30 Kc2 Nd4+ is mate.
I don't know if black has more then draw in this one, i would assume he has, but i can't find it. Time to check.
---
Ahhhhh, Na4, what a nice move that threatens to take on b2.
Too bad i didn't look harder, so zero for me today, altough the variations i gave are correct, it's just that i haven't seen the right move rather then failing to calculate anything, or missevaluating the position, so 5/6 this week, due to missing Thursaday's puzzle. |

Interesting line - as a player of the Fischer-Sozin, I have sacked many pieces on e6 in the past. Interestingly, Fischer gives it as "equal at best" generally speaking, for white, in MSMG. For Club play, it's a powerful sac, and black has to defend incredibly carefully. In the line you gave, how about 19...Qc4!? Best play goes: 20.Nxb4 Qxb4 
click for larger viewand black has much better chances than in your line, I believe. 19...Qb8!? looks lost. -Garech |

 | | James D Flynn: Black is a pawn up but appears to be n great difficulty because White threatens m ate by 27.Qxh7#. There is no way to defend h7 so Black needs either to check immediately or divert the White Q by h6 or h5 then after Q xh6 or h5 then check. The disadvantage of the Q diversion is that when the White Q takes she no longer needs th support of the R to mate on h8 so an immediate check seems likelier. There are only 2 checks available 27.Nc3+ or Rxb2+. 27…..Rxb2+ 28.Kxb2 Qb5+ 29.Qb3 and Black has run out of checks and is a R down or 28….Rb8+ 29.Kh2 h6 or h5 30.gxh6 (not Q xh pawn Nc3 mates) and now Kh7is forced to prevent mate and 31.Qa3 repulses Back’s attack and he is simply a R down. Therefore 27……Nc3+ is forced.
27……Nc3+ 28.Kc1(not Ka2 Ra4+ 29.Kb3 Qb4+ 30.Kc2 Nxd1+ 31.Kxd1 Ra1+ 32.Ke2 Qxb2+ 33.Ke3 Rc3+ 34.Bd3 Re1+ nor Kc2 Rxb2+ 29.Kxb2 Qb4+ 30.Kc2(not Kc1 Na2#) Ne2+ 31.Kd3 Nxf4+ 32.Ke3 Nxh3)Ne2+ 33.Kd2(if Kb1 Rxb2+ 34.Kxb2 Qb4+ 35.Ka2 Qa4+ 36.Kb2 or Kb1 (if Qa3 Rc2+ 37.Kb1 Nc3+ 38.Qxc3 Qa2#) Rb8+ 37.Qb3 Rxb3#. |
|
| Mar-10-13 | | Marmot PFL: The obvious move is 27...Nc3+ 28 Kc1 (or Kc2) Na4+ 29 Kb1 (Kd3 Rb3+ or Kd2 Rxb2+ both lose quickly), now many players might just repeat moves with 29...Nc3+ unless they see the power of 31...Qa3, which I missed in my very brief analysis of the position. |

 | | David2009: Minic vs Fischer, 1970 Black 27...? Insane Minic is threatening mate starting 28.Qxh7+ but (since it's a puzzle) we know that Fisher gets there first. The question is how? Try 27...Nc3+ expecting 28.Kc2. Now Black has a choice: 28...Ne2+ or 28...Rxc2+. I choose Ne2+ since this is also the response to 28.Kc1. 29.Kd2 looks forced allowing 29...Rxc2+. Here and earlier/later, Kd3 loses the Queen to Nxf4+. Now 30.Ke1 loses quickly to Qb5+ 31.Kf2 Nxf4+ etc which leaves 30.Ke3 when Black can choose between Rb3+ 31.Kxe2 Rxh3 32.Rxh3 Kxg7 and should win on material, or pursuing the King hunt with 31..Qc5+. My problem with this line of play is that it is not "insane". Assuming I have found the solution, Fischer's play is completely rational. Time to
check:
====
To adapt a classic Fischer quote <Black played differently and won differently>. Does my solution work? Here's the puzzle position
click for larger view
colours reversed
click for larger view (Minic vs Fischer 1970 27...? colours reversed)
linked to Crafty End Game Trainer: http://www.chessvideos.tv/endgame-t... The EGT soon shows the flaw in my thinking: 31.Kc1 Ne2+ leads nowhere after 32.Kb1! Nc3+ repeating the position, so Black can either accept the draw or play Fischer's combination. The EGT <defends differently anl loses differently>, varying with 31.Kc2 Qa3 32.Bd3 Qa4+ 33.Kd2 Qxd1+ 34.Ke3 Ne4 (there may be a better move, but this prevents White's mate threat) 35.Qf1 Qxf1 36.Bxf1 a5 and I successfully converted the colours-reversed endgame because I was two Pawns up. A final thought to end Fischer week. Leonard Barden once wrote that (unless Fischer was clearly losing) <Fischer played to win in every game and with every move.> This attitude is a chess lesson in itself! |

 | | patzer2: Thanks chessgames.com for a week of puzzles from Bobby Fischer's games, celebrating the 70th anniversary of his birthday on March 9, 1943 in Chicago, Illinois. In this game, the Sunday puzzle solution 27...Nc3!!, combined with the strong follow-up 31...Qa3!, provides a magnficient example of Fischer's ability to combine defensive and offensive tactics. Fischer's attack against the White King on the Queen side provides just enough tempo to win decisive material and neutralize an eminent mate-threat on his King side. |

It does not seem to matter what White plays here, both moves (Kc1 or Kc2) seem to lose for White. [An analysis of Kc2 here:
