Jun-21-11  Samagonka: Wow! Great game, great finish, great lessons learnt...
Jun-21-11  zb2cr: Easy indeed. All forced, one side-variation. It's well-described by <Formula7>, <dzechiel>, <CHESSTTCAMPS>, <VincentL>, <rhickma4>, <lost in space>, and <TheBish>.
Jun-21-11  CHESSTTCAMPS: I agree with earlier commentary that the twin solution (that I missed) with mate off the edge is more pleasing.
Jun-21-11  Fuegoverde: 44 Bxh7+ Kxh7!, 45 Qh5+ Kxg7 (if Kg8,46 Qh8++), 46 Rxf7+ Kg8!, 47 Qh7++
Jun-21-11  MaczynskiPratten: When I first looked at this I thought it was mate in 3 after 45..Kg8 46 Qh8# and a "tw'eazy Tuesday". My mind retained the image that the g7 pawn was inviolate because it was guarded by the Queen, but it wasn't any more after 45 Qh5+. Fortunately I spotted it on the check through and then saw the Rxf7+ line, which makes it a reasonable Tuesday rather than a "tweazy". Wonder if anyone else experienced this minor hallucination, even if only momentarily?
Jun-21-11  LIFE Master AJ: 44.BxP/h7+! (Yet another greek gift.)

  Patriot: At first I don't think I noticed the bishop which caused a delay in solving this. After seeing the bishop, 44.Bxh7+ became an obvious first try and after 44...Kxh7 I noticed 45.g8=Q+ and 45.Qh5+ and thought the latter seemed easier because it offered the mistake 45...Kg8 46.Qh8#. So I continued on, 45...Kxg7 ("Should I try 46.Qxf7+ or 46.Rxf7+? 46.Rxf7+ limits black more severely.") 46...Kg8 47.Qh7#--Done! That's why I chose the game line.

  agb2002: White has a bishop for a knight.

Black threatens 44... Qxg4.

Three white pieces and a pawn aim at the black king. We can sacrifice two men and deliver mate with the other two, 44.Bxh7+ Kxh7

A) 45.Qh5+ Kxg7 (45... Kg8 46.Qh8#) 46.Rxf7+ Kg8 47.Qh7#.

B) 45.g8=Q+

B.1) 45... Rxg8 46.Qh5+ Kg7 47.Rxf7#.

B.2) 45... Kh6 46.Qh3+ Qh4 47.Qxh4#.

Jun-21-11  sevenseaman: I do see some sophistication and style in queening the 'g' pawn but the direct and workmanlike

44.Bxh7+ Kxh7 45.Qh5+ Kxg7 46.Rxf7+ Kg8 47.Qh7#
is my preferred choice. Case closed.

  kevin86: The queen and rook shall mate.
Jun-21-11  Dr. J: To settle the argument that has been raging between 45 Qh5+ and 45 g8/Q+:

45 Qh5+ is <absolutely, completely, and unquestionably> the superior esthetic and logical choice: For 45 Qh5+ the single side variation (45...Kg8) is a rapid mate-in-one, whereas for 45 g8/Q+ the single side variation (45...Kh6) is a long drawn-out mate-in-two.

And that is the <final word> on the subject.

Jun-21-11  M.Hassan: "Easy" White to play 44.?
White has a Bishop for a Knight that is considered equal

44.Bxh7+ Kxh7 (forced)
45.Qh5+ Kxg7 (forced again)
<If 45...Kg8 46.Qh8#>

46.Rxf7+ Kg8
47.Qh7#

Jun-21-11  Quad Fifties: Altanolzii Enxtuul

what a cool name :)

Jun-21-11  fyad reject: i considered and rejected the winning move - i could not find 46. Rxf7+ and thought the sacrifice went nowhere

best i could find was 44. Qf5 which i think wins the knight but not even sure about that

this was in spite of the fact that i couldn't find anything useful for the rook to do

just have to do more of these i guess

  Patriot: <fyad reject> It sounds like you started calculating this correctly but your visualization failed to find 46.Rxf7+. That's a different aspect of calculation and is improved upon by moving the pieces in your head (not on the board). Keep that up and it will help reduce the problem.

44.Qf5 is certainly a strong move and it would definitely make me uncomfortable as black. White is threatening either 45.Qxf7# or 45.Qxh7# so black needs to explore his options carefully. It turns out that 44...Qxg7 diminishes white's attack.

Jun-21-11  wals: Analysis by Rybka 4 x64:

1. (#4): 44.Bxh7+ Kxh7 45.g8Q+ Rxg8 46.Qh5+[] Kg7 47.Rxf7#

Jun-21-11  TheFocus: Nice. 8 seconds to solve that.

  ajile: <wals: Analysis by Rybka 4 x64:

1. (#4): 44.Bxh7+ Kxh7 45.g8Q+ Rxg8 46.Qh5+[] Kg7 47.Rxf7#>

44.Bxh7+ Kxh7 45.Qh5+ Kxg7 46.Rxf7+ Kg8 47.Qh7#

Since both lines mate on the same move they are both equal in value.

Jun-21-11  Nullifidian: A few four-movers for one today.

The first one I came up with was the following:

44. ♗xh7+ ♔xh7▢ 45. ♕h5+ ♔xh7 (♔g8 46. ♕h8#) 46. ♖xf7+ ♔g8 47. ♕h7#

Or

44. ♗xh7+ ♔xh7▢ 45. ♙g8=♕+ ♔h6 46. ♕h3 ♕h4▢ 47. ♕xh7#

Or

44. ♗xh7+ ♔xh7▢ 45. ♙g8=♕+ ♖xg8 46. ♕h5+ ♔g7▢ 47. ♖xf7#

Jun-21-11  WhiteRook48: 44 Bxh7+ Kxh7 45 g8=Q+ Rxg8 46 Qh5+ Kg7 47 Rxf7# works
Jun-21-11  stst: Again theme for Bxh7+ followed by Q to h file +:
44.Bxh7+ Kxh7 (this time forced, couldn't go h8 or f8 because of P@g7) 45.Qh5+ Kxg7 (Obviously not Kg8 for Qh8#)
46.Rxf7 (supported by Q) Kg8
47.Qh7#
Curious enough, g7 is heavily guarded by Bk N & Q, yet neither could rescue, nor took part in the play - a pure "K-dance!"
Jun-21-11  stst: <reasonable Tuesday rather than a "tweazy". Wonder if anyone else experienced this minor hallucination, even if only momentarily?> --

NOT Really - nowadays when CG says "Easy" - it still needs a few moves to get the job done. By "few" I refer to 3 or more, often more than not.

Yet sometimes, "Very Difficult" / "Insane" may not turn out to be so "Untouchable!"

Jun-21-11  stst: <44.Qf5 is certainly a strong move and it would definitely make me uncomfortable as black. White is threatening either 45.Qxf7# or 45.Qxh7# so black needs to explore his options carefully. It turns out that 44...Qxg7 diminishes white's attack.

-- It would prove to be a Long wind if Q goes 44.Qf5 allowing Bk ...Qxg7 - Starting from this position, it's a considerable tougher puzzle.

Jun-21-11  TheFocus: <Nullifidian>

<44. Bxh7+ Kxh7only move 45. Qh5+ Kxh7 (Kg8 46. Qh8#) 46. Rxf7+ Kg8 47. Qh7#

Or

44. Bxh7+ Kxh7only move 45. Pg8=Q+ Kh6 46. Qh3 Qh4only move 47. Qxh7#>

You want to check these again? Both of these are illegal.

Jun-21-11  PhilFeeley: I actually got the whole sequence of moves this time.

Anybody want to try to guess move 24 of Alekhine vs Verlinsky, 1918? I'm surprised it hasn't been a puzzle yet.
