 | | FSR: 36.Rg8+ Kxg8 (36...Kh7 37.Ng5+; 36...Kf6 37.Qd8+ Ke6 38.Ng5#) 39.Qd8+ Kg7 40.Bf8+ Kg8 (40...Kh7 41.Ng5+ Kg8 42.Bh6#) 41.Be7+ Kg7 (41...Kh7 42.Ng5+ and 43.Qf8#) 42.Qf8+ Kh7 43.Ng5#. |
|
| Jun-22-17 | | ChessHigherCat: Black can force a trade of queens with Qxf2 if need be, so whatever white does it has to be forcing, most likely a series of checks. If 36. Rg8+ Kf6 (36...Kh7 37. Ng5+ with a quick mate and if 36..Kxg8 37. Qd8+ Kh7 39. Ng5+ leads to the same position) 37. Qd8+ Kg7 38. Rg8+ Kh7 39. Ng5+ Kh6 40. Qf8#. Not so hard for a Thursday, if all that's right. Time to look. |
|
| Jun-22-17 | | patzer2: For today's Thursday solution, 36. Rg8+ forces mate. For an early improvement, Stockfish 8 suggests ditching 17...Nfd7?! and replacing it with 17...Ncd7 = (0.00 @ 34 depth.) |

| Jun-22-17 | | ChessHigherCat: Making the Zuckertort a piece of cake |
|
| Jun-22-17 | | mqhelisi: Got it better recovery after missing the shorter route on Monday 39. Ng5+ lingering after Kh7 |
|
| Jun-22-17 | | Prosperus: 36. … Kh7 37. Ng5+ Kxg8 (37. … Kh6 38. Ne6+ Kh7 39. Rg7+ Kh8 40. Qd8#) 38. Qd8+ Kg7 39. Qf8+ Kf6 40. Nh7+ Ke6 41. Qe8+ Qe7 42. Qxe7# |
|
| Jun-22-17 | | Eusebius: Wow. All of the sudden Black's position appears like a holey piece of cheese. |
|
| Jun-22-17 | | gofer: I found this POTD much easier than yesteday's, the theme of the rook
forcing the king to a square where entry is possible for the
queen was somehow much easier to spot than the "X-ray"... <36 Rg8+ ...>
36 ... Kh7
37 Ng5+ Kxg8 (Kh6 38 Bf8#)
38 Qd8+ Kg7
39 Bf8+ Kg8/Kh8

<36 ... Kxg8>
<37 Qd8+ ...>
37 ... Kh7

38 ... Kh7
39 Ng5+ Kg8/Kh8

<38 ... Kg8/Kh8> At this point white is sploit for choice...
39 Be7+ Kg7 (Kh7 40 Ng5+ Kg7 41 Qf8#)
40 Qf8+ Kh7
41 Ng5#
But the following has one less variation, so is slightly preferable?! <39 Bh6+ Kh7>
<40 Ng5+ Kxh6>
<41 Qh8#>

| Jun-22-17 | | Sokrates: A wonderful demonstration of the most charming aspect of chess: mind defeating matter. Admittedly, I had to look for a minute before the first move came to me, probably because I didn't notice that the square d8 was vacant for white's queen. Brilliant combination by Ahmed Adly. |
|
| Jun-22-17 | | saturn2: White is up a piece and Black has threats on the queenside like Rc2 or bxa2
36 Rg8+ is decisive. I went through the answers KxR, Kh7, Kf6 and found no good way for black to continue. |
|
| Jun-22-17 | | et1: very well done. missed in tompletely because of its brilliance. |
|
| Jun-22-17 | | eblunt: Isn't white a piece up and winning already ? |
|
| Jun-22-17 | | Lambda: 36. axb3 and winning with the extra piece and passed pawn seems to work too. The only chance black has to shake things up is to try to get his rook to the second to attack f2, but on 36... Ra6 white can just bring his rook back to c2 via c8, and on 36... Qc7 white can force queens off with 37. Qd8 and then put something on d2. |
|
| Jun-22-17 | | Nosnibor: Got it in two seconds. This is more like a Monday or Tuesday puzzle. |
|
| Jun-22-17 | | JTV: After 35...Kg7, it's mate in six... |
|
| Jun-22-17 | | agb2002: White has an extra bishop.
Black threatens Rc2 and bxa2.
White can start a mating attack with 36.Rg8+:
A) 36... Kxg8 37.Qd8+
A.1) 37... Kg7 38.Bf8+ (38.Qf8+ Kf6)
A.1.a) 38... Kh7 39.Ng5+ Kg(h)8 40.Bh6#.
A.1.b) 38... Kg(h)8 39.Bh6+ Kh7 40.Ng5+ Kxf6 41.Qf(h)8#. A.2) 37... Kh7 38.Ng5+ Kg7 (38... Kh6 39.B(Q)f8#) 39.Bf8+ Kg(h)8 40.Bh6#. B) 36... Kf6 37.Qd8+ Ke6 38.Ng5#.
C) 36... Kh7 37.Ng5+ Kxg8 38.Qd8+ Kg7 39.Bf8+ Kg(h)8 40.Bh6#. -----
Much quicker than 36.axb3. |

| Jun-22-17 | | BOSTER: 29...Re8 or Rc6 and black had no problem. |
