| ex0duz: Cogano, black cant stop Rb8++. For instance;
47. Qxe6 48. Qxa6+ Qxa6 49. Rb8++
47. Nc7 48. Qxa8 with the same threat of mate at b8 with 2 passed pawns on the 6th rank just prove to be too much for black. |

| Cogano: <ex0duz> Thanks for the explanation. But, if 47... Qxe6, then 49.Rb8 is not mate, since 47...Qxe6 freed up the d7 square for the King to escape to! &, 47...Nc7, 48.Qxa8? What ever happened to Black's a7 pawn? I'm sure you meant 48.Qxa7. Thanks again. If I may trouble you further, what do you think of 47...Rh7? It seems to give Black a chance: 47.Qxa5 Rh7, 48.Qxa6+ Rb7, 49.Rxb7 Qxb7, 50.Qxc4+ Kd8, 51.e7+ Kd7 & White's checks run out. But I may have missed something. Thanks much again. Take very good care & have a great week end. Cheers mate! |

| ffire: <Cogano> If 47 ... Qxe6 => 48. Rb8+ Nxb8 49. Qc7# If 48 ... Kd7 49. Rd8+ Kc6 50. Qxa6# |

| TTLump: <ex0duz: 47. Qxe6 48. Qxa6+ Qxa6 49. Rb8++> sorry that's not mate, the King has the d7 escape square after Qxe6, however mate is still accomplished as follows:
after 47. ... Qxe6,
48. Rb8+ Kd7 (not Nxb8, else Qc7#)
49. Rd8+ Kc6
50. Qxa6#
and if Black plays 47. ... Nc7, then
48. Qxa7 (threatening Qb8#) Na6
49. Qb8+ Nxb8
50. Rxb8#
or if Black tries 47. ... Rh7, then
48. Qxa6+ Rb7 (of course not Qxa6, else Rb8#)
49. f7 Kd8 (not Bxf7, else exf7 and the pawn can't be stopped) 50. Qxc6 Bxc6
51. f8=Q+ Be8
52. Rxb7 a6
53. Rb8#

| melianis: Again, a sunday puzzle that i've seen before. This is the kind of "intuitive sacrifice", which could happen in my game, if i'm in a properly violent mood. Originally thought that a pawn roller may be possible. |

| ckr: Piece of cake, same solotion as Saturday! |

| NBZ: I saw both the ideas of Nxd5 and Rxa5 but only calculated Nxd5 exd5 e6 Qh7?? (forgetting all about the c6 square) when e7 Rd7 Rxa5! bxa5 Qe5 mates. |

| Richard Taylor: I thought that the following was the idea - similar to that above - and wins as easily (alhtough Suetins idea of suinfg the 2 Bishops is a bit more impressive aesthetically): 41. Rxa5 bxa5 42. Bxd5 Rxd5 43. Nxd5 exd5 44. e6 Qc6 45. Qd5 or f7 Black has 44. ... Qc6 43. Qd5 Nc7 48. f7 but Whte wins easily. |

| Richard Taylor: I at first thought of 41. Rxa5 bxa5 42. Nxc4 and if dxc4 43. Bb7+ but then Kd7 44. Bxa6 but its not so clear but if 42. Qxc4 Qxc4 43. Bb7+ Kd2 44. Bxa6
But it's possible that line wins also.
That wasn't too clear either but I knew the b file needed to be opened then I thought of sacrificing on d5 or playing f7 Fascinating game! |

| Richard Taylor: The way Suetin played was the most economical and hence the most beautiful and decisive - superb combination! Suetin's name appears in "The Soviet School of Chess" aand also he wrote "Three Steps to Chess Mastery" - I have both books. |

| macphearsome: 41. Nxc5 just seemed intuitive to me.
after 41...exd5 white gets a dangerous passed pawn and a beautiful open diagonal for the black bishop. As a puzzle I'd say it didn't seem as impossible as the rest of the puzzles that we usually see in the later half of the week, but I don't mind. I don't usually get anything after wednesdays anyways :P |

| Richard Taylor: <ckr: 23 minutes and I was proud as a peacock! 41.Rxa5 bxa5 42.Nxc4 dxc4 43.Bb7+ Kd7 Bxa6 and Black's goose is cooked. but as usual, I blew it. >
No you didn't - you were on the right track I think that you found line also wins (I also found it) - but from then you just needed to persist and think of how to knock a hole in the centre and get possibly a quicker win - I don't feel I "blew it" by choosing Rxa5 and then Bxd5 as it also wins I think - the two passed pawns are what win and the Ron the b file sending it's laser beam down cutting off room for the Black King. Also the opening of the diagonal for W's black squared B. I could see Black was lost at he end but didn't bother to calculate the details. Suetin just found the most precise and beautiful of probably a number of winning methods. |

| Cogano: Hi <TTLump>. I'd really appreciate it if you'd clarify some things to me. You said that if 47...Rh7, then 48.Qxa6+ Rb7, 49.f7. First,
if you'll forgive my ignorance, why f7, & what would be wrong with Black playing 49...Qxa6? Thank you kindly for
sharing your insight with me. I truly appreciate it. Take very good care & enjoy what's left of the weekend. |

| alefromitaly: Hi <Cogano> and I hope this finds you well ^_^ 50. fxe8=Q# (or 50. fxe8=R# if you prefer) |
|
| Feb-05-06 |
| Cogano: Hi <alefromitaly> & I sincerely hope this finds you well. How could I have been so blind? Thank you for pointing that out. Take very good care & enjoy what's left of the weekend. Cheers! |

| Georgie Dubb: Got it too fast : the fact that the quote of the day (“In general ... two connected passed pawns on the sixth are winning. To draw, the defender can't allow the pawns to get that far!” Jeremy Silman) is the same as yesterday’s one quickened my solving process a lot... Learning is repetition. |

| percyblakeney: The first two moves of the solution actually looks like something I could play without calculating properly since it feels as if it must be winning in some way (even if it often turns out that it isn't...). Here I didn't look at 43. Rxa5 and instead had the continuation 43. e7 which of course is worse but also ought to be winning. |

| silvio: ffire's answer to Cogano's 47...Qxe6 isthe correct one. On 47..Qxe6 White answer is NOT 48.Qxa6?! but indeed
48.Rb8 + leading to mate. Quite obvious I must say
|

| fizixgeek: It took me a while to understand 45. Bxd5. If 45. ... Qxe5, then 46. Bb7+ Kc7 47. Bxe5+ Kc7 and 48. Bxa6 leaves the Black king back in his hole without the protection of the a6 knight. Probably obvious to the rest of you, but it took me a minute. |

|
| ckr: <Richard Taylor> 43.Bb7+ Qxb7 is what I didn't see and White's goose is cooked. |
|
| Feb-05-06 |
| grobmaverick: I got the 1st 4 moves for white but this is the 1st time I have tried solving the problem on a full size board rather than a computer screen in 2d plus during a match you have to do this all in your head. Still there is hope for me yet. |

 |
| cu8sfan: Wow! I saw the idea of  xd5 followed by e5-e6 and also  xa5 followed by threats down the b-file. Even though I didn't get the whole combination this is the closest I've ever gotten to solving a Sunday puzzle. |

| kevin86: Morphy's Opera House game has seemed to flow through this week's problems.Here the threat is : xa6+ xa6 b8#-black is at loss to find an escape. |
|
| Feb-05-06 |
| lopium: I got it too, my first sunday.... by intuition, not calculous though. |

| patzer2: White prepares a decisive passed pawn with the sham sacrifice 41. Nxd5!! |
