 | | Phony Benoni: Sweet. |
|
Feb-14-18 | | dumbgai: Dang, this was a tough one for me. Didn’t find Qe5. |
|
Feb-14-18
 | | FSR: I saw 45.Qe5!?, but didn't realize the strength of 45.Rxf7! Kxf7 46.Qe5! |
|
Feb-14-18 | | stacase: For a while I thought White could snag the Black Queen, but Rook x Knight looked better and better. |

 | | al wazir: Got it.
45. Rxf7 Rxg2+ 46. Rxg2+ Kxf7 47. Qe5 Re4 48. Rg7+ Kf8 49. Qf6+ Ke8 50. Rg8+ Kcd7 51. Rd8+ Kc7 52. Qd6+ Kb7 53. Rb8+ Ka7 54. Qc7+ Ka6 55. Qb6#. Sacking the exchange one move earlier would have worked just as well. |
|
Feb-14-18 | | Fish55: <FSR> Same as you. |
|
Feb-14-18 | | stst: getting late ... kick off this quiet but quick line:
45.Qe5 (eyeing Qb8)
IF (A)..............NxQ, 46.Rd8#
IF (B)...............Kh7
46.RxN+ .... no more defense for Black |

 | | An Englishman: Good Evening: One might think that Larsen would have been nicer to someone who played the Larsen Defense. |
|
Feb-14-18 | | stst: yes, CG POD now prefers more direct and forceful attacks, rather than subtle maneurvers. RxN is stronger! |
|
Feb-14-18 | | NBZ: I had Rxf7 Kxf7 Qh8, which also appears to win fairly comfortably. |
|
Feb-14-18 | | agb2002: White has a bishop and a pawn for a knight.
White can start an attack the black king with 45.Rxf7 (45.Ra8+ Kh7 46.Rd7 Rxg2+ 47.Kxg2 Qe2+ seems to win for Black) 45... Kxf7 46.Qe5: A) 46... Re6 47.Rd7+ and mate soon.
B) 46... Rf6 47.Rd7+ Kg8 48.Qxf6 wins.
C) 46... Rxg2+ 47.Rxg2 and the threat Rg7+ is decisive (47... Re4 48.Rg7+ Kf8 49.Qf6+ Ke8 50.Rg8+ Kd7 51.Rd8+ Kc7 52.Qd6+ and mate in three). D) 46... Rg8 47.Rd7+ and mate next.
E) 46... Qh4 47.Rd7+ and mate in two. |

Feb-14-18 | | patzer2: Count me among the crowd that picked the difficult win with 45. Qe5 +- (+3.89 @ 30 ply, Stockfish 8) for their Wednesday puzzle solution, but wished instead we had seen the stronger game line 45. Rxf7 Kxf7 46. Qe5 +- (+56.51 @ 30 ply, Stockfish 8). Black's decisive mistake appears to be 35...Qh5 allowing 36. Rd3 +- (+2.12 @ 28 ply, Stockfish 8). Instead, 35...Ng4+ 36. Kg1 Qxe1+ (+0.92 @ 30 ply, Stockfish 8) puts up much more resistance and gives the second player practical drawing chances. Earlier, instead of releasing the tension with 13...Bxf3 14. Qxh6 ⩲ to = (+0.26 @ 28 ply, Stockfish 8), I prefer maintaining it with 13...Nf6 = (0.06 @ 29 ply, Stockfish 8). |
|
Feb-14-18 | | mriddle: I considered 45. Rxf7 Kxf7 46. Qe5, but went with 45. Qe5, thinking I saw a quicker path to a win that way. It looks like I missed a couple responses by black that could make things trickier though: 45... Rg7 and 45... Nd6 (with the possibility of following it up with 46. Rxd6 Rxg2+ 47. Kxg2 Qe2+ which I believe leads to a perpetual check) |
|
Feb-14-18 | | saturn2: I found the game continuation. |
|
Feb-14-18 | | mike1: If Larsen would have played the exchange sac straight away it would
have been a most impressive start of a sequence I have seen for a long time.
41.R1d2 b5, 42.b3 43.Qa1 44.Rxf7 45.Qe5
Would have.. but no, did not Qe5 myself |
|
Feb-14-18 | | cocker: I looked at the game line but didn't realise how strong it is. 46 Qh8 is just as good. |
|
Feb-14-18
 | | ajk68: I went with the follow up of Qh8. Not quite as smiting as Qe5, but still easily winning. |
|
Feb-14-18 | | malt: Gone for 45.R:f7 K:f7 46.Qe5 R:g2+
(46...Re6 47.Rd7+ Ke8 48.Q:e6+) 47.R:g2 Re4 48.Rg7+ Kf8 49.Qf6+Also 46.Qh8 |

Komodo rates it as +1.8 for White. Enough for the win, but not as clean a kill-shot as the game continuation. |

|
Feb-14-18 | | dfcx: Like others, I also went with 46.Qh8, which appears to be as good as Qe5. |
|
Feb-14-18
 | | paulalbert: I also went with 46 Qh8, after looking for a few seconds. Be curious to know from someone who has time to analyze or has an engine whether that is also good. |
