Sep-02-15  thegoldenband: <al wazir: I chose 59. Qxg5+. 59...Kxg5 is again stalemate, but after 59...Ke6 60. Qxh4, there's lots of play left, with black definitely having the better game.>

I can't really see this -- in practical terms it looks to me like a dead draw after 60. Qxh4, and in any event it's a tablebase draw.

Sep-02-15  dfcx: white is down two pawns and does not have any chance of winning. So the only option is to draw.

58.Rxf6+!

A. 58...Kxf6 59.Qb6+ Qxb6 stalemate

If black refuses the rook,

B. 58...Kh5 59.Qe2+ g4 60.Rf5+ Kg6 61.Rb5 and white is winning.

C. 58...Kg7 59.Qxg5+ wins

D. 58...Kh7 59.Qxg5 wins the rook, if 59...Rh1 60.Qg6+ Kh8 61.Rf8#

  patzer2: The prompt of a daily puzzle made today's Wednesday solution 58. Rxf6+! Kxf6 59. Qb6+ Qxb6 with stalemate easy for me.

Where might Black improve?

Well for one, instead of 51...f5 =, Black can secure a strong advantage with 51...Kg8! (-0.87 @ 22 depth, Deep Fritz 14) when play might continue 52. Rc4 g6 53. Rc8+ Kg7 54. Rd8 Kh7 55. Rd2 Qb4 56. Qxg5 Qb3+ 57. Kg4 Qxb6 58. Qf6 Qb4+ 59. Kg3 Qc3+ 60. Kg4 Qc4+ 61. Kg3 Rf1 62. Rf2 Rxf2 63. Kxf2 Qd4+ 64. Kf1 Qd3+ 65. Kg1 Qb1+ 66. Kh2 Qf5 67. Qh4+ Kg7 (-2.20 @ 22 depth).

  agb2002: White is two pawns down.

Black threatens 58... Qb8+ 59.Kf2 Rf4+ 60.Ke2 (60.Ke1 Qb1+ 63.Kd(e)2 Qa2+ wins the rook; 60.Kg3 Rf3+ 61.Kg4 Qg3#) 60... Qb2+ 61.Kd(e)1 (61.Qd2 Rf2+ wins) 61... Qb1+ wins the rook as in the first subline.

The white king can only move to f2. This suggests 58.Rxf6+:

A) 58... Kxf6 59.Qb6+ Qxb6 stalemate.

B) 58... Kg7 59.Qxg5+ mates in four.

C) 58... Kh7 59.Qxg5 wins.

D) 58... Kh5 59.Qe2+ g4 (59... Rg4 60.Qxg4#) 60.Rf5+ Kg6 61.Rb5 Qh7 62.Qxe4+ wins. For example, 62... Kf5 63.Qc6+ Kg7 64.Rb7+ Kh8 65.Qf6+ and mate next.

Sep-02-15  Kyudaime: 58. Rxf6+! Kxf6 (58...Kg7 59. Qxg5+ 1 - 0) 59. Qb6+ draw

  morfishine: <al wazir> 59.Qxg5+ doesn't lead to stalemate since after 59...Kxg5 White has 60.Kf2 and is lost
Sep-02-15  schachfuchs: I got also a 3-step solution:
1st idea was: "stalemate"!
2nd step was: How do we get Black guard the last free square f2? 3rd was the joy after finding the detailed realization 58.Rxf6+ Kxf6 59.Qb6+ Qxb6 =

  gofer: After a few minutes of staring at this one, I don't see how we can be looking for a win, we must be playing for a draw. We are nearly in a mating net all we need to is put Qb7 on b6 and the net is complete!

<58 Rxf6+! ...>

58 ... Kg7/Kh7
59 Qxg5+

<58 ... Kxf6>
<59 Qb6+! Qxb6 (forced)> draw

~~~

Yep.

Sep-02-15  saturn2: I had the stalmate idea of al wazir but soon verified it does not work. The solution honestly I did not see.

To my apologize I have to say I assumed the puzzles to be constructed to find a winning move. So I wasted sometime to find mating motives bringing the rook to the 7th rank with tempo after Qa3 for instance.

Sep-02-15  wooden nickel: White probably had seen the stalemate a move earlier before 57.Re6!

Did Black also see it coming? ... alternatives to 57... Qxb7 don't seem much better.

  CHESSTTCAMPS: Black, with two connected passed pawns to the good, would seen to have a won ending, but white can force a draw with 58.Rxf6+!! Kxf6 (not 58...Kh7?? 59.Qxg5 R moves [e.g. Rh1] 60.Qxg6+ Kh8 61.Rf8#) 59.Qb6+ Qxb6 stalemate.

If you understand what white needs, it's much easier to find.

  Bubo bubo: White, being down two pawns, saves the day by forcing stalemate: 58.Rxf6 Kxf6 59.Qb6+ Qxb6. Refusing the sac does not help, as 58...Kh5 59.Rh6+ Kxh6 60.Qb6+ leads to the same result, while 58...Kg7/h7 59.Qxg5(+) even loses.
Sep-02-15  vodkaboris: Damn. On the right lines - realised it had to be a stalemate and so had to shut off f2 as an escape square for the white king - but didn't see it all the way through.
Sep-02-15  Herma48852: Completely clueless. Hats off to those who solved it.

  Jimfromprovidence: <dfcx> <58...Kh5 59.Qe2+ g4 60.Rf5+ Kg6 61.Rb5 and white is winning.>

This line is more interesting than the stalemate, IMO, especially after 60...Kg6.

Because 1 Rc5! also wins.

The side analysis is to figure out why this move works.

It's worth pointing out that White can still play for the stalemate with <59.Rh6+>. That's what usually happens in these Fire Sale Stalemates. In this case, of course, White would play for the win with 59.Qe2+, as several analysts have mentioned.

  kevin86: A very deft stalemate trap! White rescues a game down two pawns.
Sep-02-15  Howard: Andy Soltis mentioned this position briefly in one of his monthly columns once. It was back in the 1990's I think.

  al wazir: <morfishine: 59.Qxg5+ doesn't lead to stalemate since after 59...Kxg5 White has 60.Kf2 and is lost.> You're right. How embarrassing.

  Longview: Saw Rxf6 and Qb6 as starting moves but missed the forced stalemate entirely. Cool escape.
Sep-02-15  Howard: Any more suggestions as to how Black could have won this game ?
Sep-02-15  Imran Iskandar: I figured that I needed to force a stalemate but I couldn't find the combination.
