 | | Phony Benoni: Not that easy, because so much is going on.. If you don't get lucky quickly, it takes a while to slice through the thickets. |
|
| Jul-11-17 | | Walter Glattke: 36.Qh5 Nh7!? 37.Rxc8+ Kg7 38.Rxh7# |
|
| Jul-11-17 | | agb2002: White has a bishop and a pawn for a knight.
Black threatens Q(R)xc4 and bxc3.
White can unpin the rook on c4 while creating two threats (Rh8+ and Rxc8) with 36.Qh5: A) 36... Q(R)xc4 (or 36... bxc3) 37.Rh8+ Kg7 38.Qh6+ Kf7 39.Qf6+ Ke8 40.Rxf8+ Kd7 41.Qd6#. B) 36... Rh7 37.Rxh7
B.1) 37... Nxh7 38.Rxc8+ and mate soon.
B.2) 37... Q(R)xc4 38.Rh8+ as in A.
C) 36... Nh7 37.Rxc8+ wins.
D) 36... Rc6 37.Rcxc6 wins (37... bxc3 38.Rh8+ as in A). E) 36... Rd8 37.Rh8+ as in A. |

| Jul-11-17 | | diagonalley: <phony benoni> ... well put ... difficult for a tuesday puzzle (<diagonalley>: nul points) |
|
| Jul-11-17 | | AlicesKnight: I saw 36.Qh5 Qxc4; 37.Rh8+ Kg7 and then missed the much easier 38.e5 completely! - going with Qh6+ Kf7; 29.Qf6+ Ke8; 40.Rxf8+ Kd7; 41.Qd6 (so laborious!). |
|
| Jul-11-17 | | gofer: The most forcing move is <36 e6> threatening <37 Rh8#>, so lets
see where that leads...
<36 e6 ...>
36 ... Nxe6?
37 Qxe6+ Kf8
38 Rh8#
36 Rg7 Qh5
37 Rh7 Qf7+!!! (Nh7 38 Rxc8# Qe8 39 Rxe8#)
38 Rxf7 Rh8#
<36 ... bxc3>
<37 Qh5 ...>
Now white threatens <38 Rh8+ Kg7 39 Qh6#>, so black still has to find a defence
but now Rc4 is free to take Rc8!
37 ... Kg7
38 Qxg5+ Ng6
39 Qxg6+ Kf8
40 Qf6+ mating
37 ... Nh7
38 Rxc8+ 
<37 ... Qb1+>
<38 Kh2 ...>
Black has delayed the decision how to defend against <39 Rh8+ Kg7 40 Qh6#> by one move, but the decision still has to be made... <38 ... Rh7>
<39 Rxh7 Nxh7>
<40 Qg6+! Kh8> (Kf8 41 Qf7#) <41 Rxc8+ Qe8> <42 Rxe8+ Nf8>
<43 Rxf8#>
~~~
Doh! Hmmm, okay, but a win is a win is a win... |
|
| Jul-11-17 | | saturn2: 36 Qh5 and black cannot take the rook on c4 because mate is threatend. So RxRc8 is looming. |
|
| Jul-11-17 | | cocker: <Whitehat1963> got it right all those years ago - more suitable for Thursday/Friday. |
|
| Jul-11-17 | | MrCarciofo: I would have played 36. e6 - and if ...cxb3 then Qh5, Qb1+; Kh2, f4; Rh8+, Kg7; Qh6#. But Qh5 is more safe and quick. |
|
| Jul-11-17 | | whiteshark: <36.e6> would have been my choice, too. |
|

 | | Willber G: Looks like I'm the only one who went for the rook sac (it is Tuesday, after all) which, on further examination, works perfectly right up until the point that it fails. |
|
| Jul-11-17 | | Pasker: Very difficult puzzle. It should not be a Tuesday. 38...e6+ is the key move in this combination. |
|
| Jul-11-17 | | kevin86: White pieces in position ,black's not to defend. |
|
| Jul-11-17 | | DrGridlock: <Pasker> Agreed that e6+ is the key move in the combination. The deeper key is understanding that the "value" in e6+ is NOT in the discovered check by the bishop on c3 (since it can be taken easily enough by the b-pawn), but IS to cover the f7 square and cut off the black king's escape route. |
|
| Jul-11-17 | | swclark25: <sensex: 36.Qh5 QXR or PxB 37.Rh8+ Kg7 38.Qh6#> In this case, looks like 38...Kf7 would avoid mate since white never moved e6. However, I wonder if your proposed 36)...bxc3 would have helped black survive? |
|
| Jul-11-17 | | botvinnik64: Easy; could have been Monday puzzle, guys, cmon. What else to play with so many of white's pieces en prise? Nice finish. |

 | | doubledrooks: I cast my vote for 36.Qh5. For example, 36...Rh7 37.Rxc8 bc 38.Qg6+ Rg7 39.Rh8+ Kxh8 40.Rxf8+ Rg8 41.Rxg8# |
|
| Jul-11-17 | | NBZ: Unfortunately I missed e6+ but did find a much slower and more cumbersome way to mate the black king: Qh5 Qxc4 Rh8+ Kg7 Qh6+ Kf7 Qf6+ Ke8 Rxf8+ Kd7 Qd6# |
|
| Jul-11-17 | | Tiggler: With engine help (Houdini) I find that 36.e6 is M+21, but 36.Qh5 is M+5. I made the wrong choice (e6), and needless to say, did not see all the lines that make it mate in 21. |
|
| Jul-11-17 | | Cheapo by the Dozen: I rarely whiff on a Tuesday, but in this case I was too concerned about the ... Rh7 defense. The biggest thing I overlooked was that Rxc8 pins the knight. |
|
| Jul-11-17 | | drollere: i had Qh5+ sacrificing the rook for plenty of tooth on the black K. <I overlooked was that Rxc8 pins the knight.> the white Q is hanging. |
|
| Jul-11-17 | | morfishine: Seemed like the whole game Black had one foot in Duh-grave ***** |
|
| Jul-11-17 | | patzer2: Got the first two moves of today's Tuesday puzzle 36. Qh5! Qxc4 37. Rh8+ Kg7 (diagram below):
click for larger viewHere (diagram above) I calculated mate-in-four with 38. Qh6+ Kf7 39. Qf6+ Ke8 40. Rxf8+ Kd7 41. Qd6#. Faster instead was the game continuation 38. e6!, which I missed, with mate-in-one to follow. P.S.: For a Black improvement Stockfish 8 recommends 26...Rbc7 = as a replacement for 26...g5?!, which weakens the King side by allowing 27. h4  . |

 | | gawain: I was obsessed with trying to make 36 Rh8+ work. And it doesn't. I considered 36 Qh5 but I did not pursue that very hard as it did not feel like a Tuesday puzzle solution. (Isn't that a pathetically feeble excuse!) |
|
| Jul-12-17 | | ChessHigherCat: <gawain: I was obsessed with trying to make 36 Rh8+ work. And it doesn't.> Everything would be a lot easier without that sneaky little black pawn on b4! |
