Apr-28-06  babakova: I got this one...Rather straightforward calculating. But I dont see what the fuss and praise is about 43.Qc7, to me it seems like an obvious move, getting the queen out of exchanging and making way for the passed pawn.
Apr-28-06  Summum Malum: A little easy for a friday isn't it??
Apr-28-06  Catenaccio: I solved my first friday:
either I am getting better or Chessgames is still making up for the tough start of the week
Apr-28-06  RandomVisitor: This whole combination is possible because of the weak move 37...c4.

If Black had played something like 37...a5, then he could play 43...Qe1+ 44.Ka2 Qe6+ 45.b3 a4 and hold on.

Apr-28-06  SickedChess: because all is forced I got it easily
Apr-28-06  LIFE Master AJ: I found 39.Rd7 almost right away, which Fritz says is winning easily. (I didn't bother to look for anything else.)
Apr-28-06  LIFE Master AJ: Good puzzle - thank you (to) Chess Games!

Apr-28-06  chiguire: I am sure that I am missing something, but why doesn't black play 37 ...Rxd6? If black plays 37 ...Qxd6 I can see desaster ahead for black, but I can't work out a sure win for white if black play 37 ...Rxd6.

Like I said, I am probably missing something, but if someone could enlighten me I would be very appreciative.

Apr-28-06  Castle In The Sky: <LIFE Master AJ> One move and going to Fritz does not count as problem solving, especially for a self-professed "strong" player.
Apr-28-06  YouRang: At first, I thought White might be grateful for a draw, and of course the perpetual check is there (shift queen between h6 and h7).

But then I found a potential win for White (not as good as the solution in the game). Let me know what you think:

39. Qh6+ Kg8
40. Ra7 Rxd6
41. Ra8+ Kf7
42. Rf8+

  technical draw: <Castle In The Sky> Do not insult AJ. He is not a "strong" player he is a master just like you and I. We masters can see a position and know, via some mystic power, what the correct continuation is.
Apr-28-06  babakova: <chiguire> 37...Rxd6?? 38.Qc8+ Qf8 39.Re8 looks like good reason to me...
Apr-28-06  Mendrys: Drats! I looked at the line: 39. Rf7+ Qxf7 40. Qh8+ Qg8 41. Qf6+ Qf7 42. Qxd8+ Qe8 but didn't see a win for white. My endgames are usually horrible anyway wich is probably true of most patzers like me. Anyone have suggestions for good endgame books?
Apr-28-06  YouRang: I've been considering other variations in the <alternate line> I proposed, but still I see White winning. For example:

39. Qh6+ Kg8
40. Ra7 Qf1+
41. Ka2 Qf6
42. Qh7+ Kf8
43. Qe7+ Qxe7
44. dxe7+

Anyway, unless someone points out a flaw, I'm going to give myself credit for finding a solution. :-)

Apr-28-06  chiguire: <babakova> thanks for the correction; Before I posted the question I followed it out that far and then continued 39 ...Rf6, but I guess that leaves black with a rook and white with a queen.

Thanks for answering my question.

  kevin86: I missed it,shucks!! I missed the fork on move 41-I thought it was a goof.
Apr-28-06  bugeyes: Yeah! This is only the third Friday puzzle I have ever solved well (In about a year and a half of trying!) This is also the first time I have solved them all from Monday through Friday! It makes a dummy like me feel pretty darn good. Thanks to all during this time who have helped me see new things through their postings! I couldn'ta done it widdout ya! Saturday, here I come! (now primed for an utterly desolating failure...) ;)
Apr-28-06  EmperorAtahualpa: Excellent puzzle in a position that seems so simple!

I sadly missed it. :( I was thinking of 39.Re6.

  Open Defence: <<YouRang:>> in your <alternate line> what about 40..♖e8 that should defend against the subsequent ♕e7+ but does that allow White any mate ? its just a thought at the top of my head so I hope I didnt blunder
Apr-28-06  Montreal1666: <eaglewing:> <<Montreal1666> and <Patzer2> You asked: Why 43. ... b4?

Before b4, White's threat was 44. d7.
If White ignores b4, there might be a danger to either be perpetualled or lose the pawn d7. If ignored, Black should try to swindle like this:

43. Qc7 b4
44. d7 Qd1+
45. Ka2 b3+
46. cb cb+
47. Kxb3 Qd1 or e6+ >

Ok. Thanks

Apr-28-06  azchess: <YouRang>, black's move 40 in your line could be stronger... if: 40. ... Rxd6, 41. Ra8+ Kf7, 42. Qf8+ Ke6, 43. Qxf6+ Kxf6 and black is ahead with a passed pawn
Apr-28-06  YouRang: <Open Defence> Hmmm. Good point-- 40...Re8 appears to be Black's best defense. However, I *think* White can still end up better:

After 39. Qh6+ Kg8 40. Ra7 Re8,
41. Rxa6 Rd8
42. Qd2 Qf1+
43. Ka2 Qf7
44. Qd4 c3+
45. b3 Qe6
46. Rb6

And I think black's queenside pawns fall.

  Open Defence: <After 39. ♕h6+ ♔g8 40. ♖a7 ♖e8,
41. ♖xa6 at the top of my head 41..♖e6
Apr-28-06  YouRang: <azchess> <black's move 40 in your line could be stronger... if: 40. ... Rxd6, 41. Ra8+ Kf7, 42. Qf8+ Ke6, 43. Qxf6+ Kxf6 and black is ahead with a passed pawn>

But in that line (the first one I mentioned above), it should go:

39. Qh6+ Kg8 40. Ra7 Rxd6 41. Ra8+ Kf7 42. <Rf8+> (not 42. Qf8+). The skewer wins the queen.

Apr-28-06  YouRang: <azchess> On the other hand, Black can improve with 39. Qh6+ Kg8 40. Ra7 Rxd6 41. Ra8+ <Rd8>. After exchanging rooks, White can take the g6 pawn (with check) and then the a6 pawn. White is better, but only by a pawn...
