|Apr-15-17|| ||detritus: Kind of a weird Saturday puzzle in that the next several moves after White's first move are pretty obvious, but you have to be careful as to how White's bishop vacates the e-file. I went with 21. Bf6, but after Black's queen captures on f6 she covers h4, a crucial difference compared to how the game actually played out.|
|Apr-15-17|| ||ChessHigherCat: Second! (tactfully declining the privilege of saying the F word). I was barking up the wrong tree here. I thought it had something to so with Bf6 Rxe1, Rxe1 with Bc2 thrown in somewhere along the line to divert the queen, but shows what I (don't) know.|
|Apr-15-17|| ||Walter Glattke: Weird, 21.Bf6 and 21.Bc2 fail, 21.Bxd6
Bd7 22.Be5 g6 23.Bxd4! (23.Bxc7? dxc3
24.bxc3 Bxf2+ with draw)one pawn for White.
|Apr-15-17|| ||Patriot: I almost went with 21.Bf6 Rxe1+ 22.Rxe1 Qxf6 23.Re8+ Kh7 and 24.Qh4+ cannot be played as <detritus> points out.|
The next logical move for me was 21.Bxd6 Rxe1+ 22.Rxe1 cxd6 23.Re8+ Kh7 24.Qh4+ Kg6 but I missed the key move, 25.g4, and didn't see anything useful. So I did some adjusting to this line and tried 23.Qh4 thinking 23...Kf8 24.Qd8# or if 23...g5 24.Re8+ Kg7 25.Qh8+ Kg6 26.Rg8#. Thanks to the pin on f7 black cannot play f6. But I missed the simple 23...Be6 which kind of throws a wrench into the machine.
|Apr-15-17|| ||protonchess: Just looking at the diagram on screen, I went for 21. Bc2 Qxc2 22. Bf6, thinking Rxe1+ 23. Rxe1 Qg6 would win for White (a check pulls the BQ to h6 where she gets skewered by Rh8+). But after looking at the solution :) I see that Rxe1 is not forced! Black has a beautiful counter 22. .. Bg4! which is almost its own puzzle, and leaves the game about equal after 23. Qxg4 Qg6 24. Qxg6 fxg6 25. Bxd4 Bxd4 26. cxd4 Kf7.|
|Apr-15-17|| ||al wazir: <detritus: I went with 21. Bf6>. Me too.|
Another possibility is 21. Bc2 Qxc2 22. Bf6 Rxe1+ 23. Rxe1 Qg6 23. Re8+ Kh7 24. Qh4+ Qh6, but that seems to give white nothing better than a draw.
|Apr-15-17|| ||protonchess: alwazir: You must have posted before you could read mine :-P|
At the end of your line, 25. Rh8+! wins. But it doesn't have to get there.
|Apr-15-17|| ||Cheapo by the Dozen: I gave up after failing to work out a successful Bf6 line.|
|Apr-15-17|| ||WorstPlayerEver: 21. Bd6 Be6 draw.|
|Apr-15-17|| ||agb2002: White is one pawn down.
Black threatens dxc3.
The first idea that comes to mind is 21.Bf6 but after 21... Rxe1+ 22.Rxe1 Qxf6 23.Re8+ Kh7 White doesn't seem to have enough compensation. This suggests 21.Bc2 to decoy the black queen:
A) 21... Qxc2 22.Bf6 Rxe1+ (22... Rf8 23.Qxg7#) 23.Rxe1 Qg6 (23... g6 24.Re8+ Kh7 25.Rh8#) 24.Re8+ Kh7 25.Qh4+ Qh6 26.Rh8+ Kxh8 27.Qxh6+ Kg8 28.Qxg7#.
B) 21... Qd7 22.Bf6 g6 (or 22... Rxe1+ 23.Rxe1 g6) 23.Qh4 and mate soon.
C) 21... Qh5 22.Bf6 Rxe1+ 23.Rxe1 Bg4 (23... Qh6 24.Re8#; 23... g6 24.Re8+ Kh8 25.Rh8#) 24.hxg4 Qh6 25.Bxd4 + - [B].
D) 21... Rxe7 22.Bxf5 Rxe1+ 23.Rxe1 Bxf5 24.cxd4 + - [Q vs 2B] (24... Bxd4 25.Qf4 wins a bishop).
E) 21... d3 22.Bxd3 doesn't seem to improve much for Black. For example, 22... Bxf2+ 23.Qxf2 Qxf2+ 24.Kxf2 f6 (to trap the bishop) 25.Bg6 Bd7 26.Bxe8 Bxe8 27.Rad1 with a won ending even after Bxd6.
|Apr-15-17|| ||agb2002: I missed 23... Qxd3 in my line E.
Better luck next time.
|Apr-15-17|| ||pawndude88: 22...Bd7 23.Be5 g6 24.Qh4 and 22...Be6 23.Be5 f6 24.Bxf6 also look bad for Black.|
|Apr-15-17|| ||morfishine: <21.Bxd6> attacking the Black rook looked best, but as Black, I would've replied <21...Be6> to clear the back rank; giving up the rook with check doesn't seem right|
|Apr-15-17|| ||patzer2: Maybe I'm missing something, but after an hour of computer analysis with Deep Fritz 15 on a fairly fast i7 processor I'm convinced that with best play our Saturday puzzle (21. ?) is a draw.|
The game move 21. Bxd6! is no doubt the most practical option because it gives White lots of winning chances with a draw in hand.
However, the option 21. Bf6, which was also my pick for today's Saturday puzzle solution, also appears to force the draw.
Here's my analysis with Deep Fritz 15:
<21. Bxd6!> The best option because it gives White the most practical winning chances. Yet with best play by Black, computer analysis suggest it yields only a draw.
However, White can also reach the best play draw conclusion with my pick 21. Bf6!?, which levels out after 21. Bf6 Rxe1+ 22. Rxe1 Qxf6 23. Re8+ Kh7 24. Rf8 dxc3 25. bxc3 d5 26.
Bxd5 Bc5 27. Rxf7 Qh6 28. Be4+ Kg8 29. Bd5 Kh8 30. Rxg7 Qxg7 31. Qh4+ Qh7 32. Qf6+ Qg7 33. Qh4+ Qh7 34. Qf6+ Qg7 35. Qh4+ = (0.00 @ 31 depth, Deep Fritz 15)
<21... Rxe1+> This probably leads to a draw, but the best option for forcing the half point is <WorstPlayerEver>'s suggestion 21... Be6 which leads to full equality after 22. Be5 f6 23. Bxe6+ Qxe6 24. Bxd4 Qxe1+ 25. Rxe1 Rxe1+ 26. Kh2 Bxd4 27. cxd4 Rd8 28. Qxc7 Rxd4 29. Qxb7 Re2 30. Qxa6 Rxb2 31. Qe6+ Kh7 32. Qf5+ Kh8 33. a3 Rdd2 34. Qh5+ Kg8 35. Qe8+ Kh7 36. Qe4+ Kh8 37. f4 Ra2 38. Qa8+ Kh7 39. h4 Rd4 40. Qa5
Rf2 41. Qf5+ Kg8 42. Kg3 Rfd2 43. Qc8+ Kh7 44. Qa8 f5 45. Qa6 R2d3+ 46. Kh2 Re3 47. Qf1 Rxa3 48. Qf2 Rc4 = (0.00 @ 35 depth, Deep Fritz 15)
<22. Rxe1 cxd6 23. Re8+ Kh7 24. Qh4+ Kg6 25. g4!?>
The computer suggests a stronger try here for White is 25. Rf8!, but it also yields a draw after the difficult and clever continuation 25...d5 26. g4 Qg5 27. Bc2+ f5 28. Qg3 Kh7 29. Kg2 Qe7 30. Rxc8 Rxc8 31. Bxf5+ g6 32. Bxc8 d3 33. Qxd3 Qf8 34. Bf5 gxf5 35. Qxd5 Qc8 36. gxf5 Qg8+ 37. Qxg8+ Kxg8 38. Kf3 Kg7 = (0.00 @ 24 depth, Deep Fritz 15)
<25... Qg5 26. Qg3 Qc1+?> This appears to be Black's decisive mistake.
Instead, it appears Black can still salvage the draw with 26... Kh7 27. Bxf7 dxc3 28. Bg8+ Kh6 29. Bb3 Bxf2+ 30. Kxf2 Bf5 31. Qxd6+ Qf6 32. Qxf6+ gxf6 33. Re1 Bg6 34. bxc3 Rc8 35. Re3 f5 36. Bc2 Kg5 37. gxf5 Bf7 38. a4 a5 39. Rd3 Rc4 40. Kg3 Bh5 41. Re3 Rf4 42. Be4 Bf7 43. c4 Bxc4 44. Bxb7 Rxf5 45. h4+ Kf6 46. Bf3 Bf7 47. Rc3 Re5 48. Kf4 Rf5+ 49. Kg4 Be8 50. Bc6 Bh5+ 51. Kg3 Re5 52. Kf4 Bd1 53. Rc4 Bb3 54. Rc1 Rh5 55. Kg4 Re5 56. Kf3 Re7 57. Rf1 Rc7 58. Bb5 Ke5 59. Re1+ Kf6 60. Ra1 Bd5+ 61. Ke3 Ke5 62. Rg1 Rc3+ 63. Kd2 Rh3 64. Rg5+ Kd4 65. Rg4+ Ke5 66. Bf1 Rh1 67. Bd3 Rh3 68. Bc2 Rh2+ 69. Kc3 Rh3+ 70. Bd3 Bf3 71. Rg5+
Kd6 72. Kd2 Rxh4 73. Rxa5 Bc6 = (0.00 @ 30 Depth, Deep Fritz 15)
<27. Kg2 > (+81.31 @ 28 depth, Deep fritz 15) After Black's not-so-obvious error with 26...Qc1+?, White is winning easily after this move (27. Kg2) as play continues
<27...dxc3 28. Qd3+ Kg5 29. Bxf7
d5 30. Rxc8 1-0> Black resigns as it's mate-in-two after 30...Rxc8 31. Qf5+ Kh4 32. Qh5# or mate-in-four after 30...Qg1+ 31.Kxg1 Kh4 32.Qh7+ Kg5 33.Qf5+ Kh4 34.Qh5#.
|Apr-15-17|| ||gofer: I got the first six moves;
<21 Bxd6 ...>
21 ... Rxe1+
22 Rxe1 cxd6
23 Re8+ Kh7
24 Qh4+ Kg6
25 g4 Kg5
26 Qg3 ...
But I didn't think black could allow this line. Like <Patzer2> and <WorstPlayerEver> I thought that black had to play <21 ... Be6>
Which could trade off as follows...
<21 ... Be6>
<22 Bxe6 Rxe6>
<23 Rxe6 Qxe6>
<24 Be5 f6>
<25 Bxd4 Bxd4>
<26 cxd4 ...>

Okay, we are a pawn up after 6 moves and before that we were a pawn down, so perhaps not too
shabby, but hardly worth writing home about...
|Apr-15-17|| ||Walter Glattke: 21.Bc2 could stoppped by later Qxd3,
but also 21.-Qxc2 23.Bf6 Bg4! would prevent the trap with Rh8+ and mate.
24.Qxg4 Qg6 seems to get draw.
|Apr-15-17|| ||nazgulord: <detritus> I made the same error of Bf6. I thought threatening mate would be the best way to open the line of attack on the back rank, but I was wrong.|

30.-Qc1+ 31.Kh2 Bb8 32.Bf7 d5 and now the magic moves: 33.g5+ Kh7 36.g6+ Kh5
But maybe FRITZ has other moves then.
|Apr-15-17|| ||Walter Glattke: Corr: 36.-Kh6|
|Apr-15-17|| ||thegoodanarchist: < patzer2: ...
However, the option 21. Bf6, which was also my pick for today's Saturday puzzle solution, also appears to force the draw.>
That was my choice too.
Proving the old adage, great patzers think alike
|Apr-16-17|| ||patzer2: <Walter Glattke> Thanks for taking a look at the line 26...Kh7 27. Bxf7 dxc3 28. bg8+ Kxh6 30 bxc3 (in place of 30. Bb3)|
I think you're right. This line does appear to win for White. Deep Fritz 15 now assesses 26...Kh7 27. Bxf7 dxc3 28. bg8+ Kxh6 30 bxc3 (+2.64 @ 21 depth, Deep Fritz 15)
So if Black is to force the draw after 21. Bxd6!, it appears 21...Be6 may be the last and only chance for the second player to survive in this line.
P.S.: Maybe Fritz was sleepy as I was this morning. In between researching the puzzle from 5 to 6 AM, I was also preparing to travel with my Grandsons and their parents to a 110 mile distant Chess tournament.
