 | | Phony Benoni: Hmmm... Discovered check possibility after <40.Qg6+ Rxg6 41.Rxg6+ Kh7>. Nothing looks particularly tasty, though. We could continue with the knight check <42.Ng5+ Kh8>, and a rook check ... no wait, it's a fork with <43.Nf7+>, making it a whole rook gained. Helps to be distractible sometimes. |
|
| Jun-03-15 | | jith1207: Easy and Humiliating! There's nothing like doing a Royal Fork, but opt not to take the queen and go for the kill instead. |
|
| Jun-03-15 | | jith1207: 42..Kh8 43. Nf7+ Kh7 and place the Rook on 44. Rg4+ (under attack from Knight and pawn). What a Sadist way to checkmate. |
|
| Jun-03-15 | | Cheapo by the Dozen: This seems simple enough:
40 Qg6+ Rxg6
41 Rxg6+ Kh7
42 Ng5+ Kh7
43 Nf7+
I'm guessing White just wins the queen and goes a rook up, plus gets another piece via a discovered check. If there's actual mate in that direct line, so much the better. ---
From the other comments, it looks like I guessed wrong. :) |

| | Phony Benoni: Oh, good grief. The closer I get to Social Security, the more I favor materiality over mating. |
|
| Jun-03-15 | | Cheapo by the Dozen: They should have a TV show called "Whose attack is it anyway?" Black seemed unclear on the point. |
|
| Jun-03-15 | | jith1207: <Phony Benoni> It might be the years of experience taking the safer route. Nothing wrong in getting there ;-) |
|
| Jun-03-15 | | Coriolis: I thought the answer was 40. Ng5 |
|
| Jun-03-15 | | diagonalley: there having been a royal fork on monday, i assumed this was just another example... didn't bother to look any further... situation normal :-( |
|
| Jun-03-15 | | patzer2: Instead of <34...Qe7 =>, Black has 34... Be7! when play might continue 35. fxg4 Qd4! 36. g5+ Kg7! 37. Rf1 Qxe4+ 38. Nf3 Qxf3+ 39. Qxf3 Nxf3 40. Rxf3 Bxg5  (-0.76 @ 27 depth, Deep Fritz 14) with Black having an extra pawn and the initiative.Black's decisive mistake was <39...Nf6??>, allowing mate-in-five with <40. Qg6+!!> (solving our Wednesday puzzle) followed by <40...Rxg6 41. Rxg6+ Kh7 42. Ng5+ 1-0> where Black resigns in lieu of 42...Kh8 43. Nf7+ Kh7 44. Rg5#. Instead of <39...Nf6??>, Black has 39... Qe7! when play might continue 40. h3 Nf6 41. Qxg8 Nxg8 42. Rxg8 Qf6 43. b3 Bd6 44. Nh4 Qxh4 45. Rg6+ Kh7 46. Rg4+ Kh6 47. Rxh4 Kg5 48. Rxh5+ Kxh5 49. Kg2 Be5 50. Bg4+  (+0.64 @ 31 Depth, Deep Fritz 14) with good drawing prospects for Black in an opposite color Bishops endgame. |
|
| Jun-03-15 | | goldfarbdj: Qg6+ was the obvious and only move; it merely required looking ahead a few moves to verify the forced mate. (I noticed the queen fork, but unlike some here I did in fact see the mate.) |
|

 | | Sneaky: Oh snap, there is a mate after all! I just saw the royal fork. But 42...Kh8 43.Nd7+ Kh6 and 44 "Rook to just about anywhere, checkmate." |
|
| Jun-03-15 | | gofer: Forced mate in 5: <40 Qg6+ Rxg6 41 Rxg6+ Kh7 42 Ng5+ Kh8 43 Nf7+ Kh7 44 Rg1#/Rg2#/Rg3#/Rg4#/Rg5#> |
|
| Jun-03-15 | | agb2002: The material is identical.
Black threatens 40... Rxg2.
White can win immediately with 40.Qg6+ Rxg6 41.Rxg6+ Kh7 42.Ng5+ Kh8 43.Nf7+ Kh7 44.Rg1(2-5)#. |
|
| Jun-03-15 | | EIDorado: I only thought about Bg6. |
|
| Jun-03-15 | | BxChess: <Phony Benoni> "materiality over mating". I guess it depends upon the position. |
|
| Jun-03-15 | | morfishine: <40.Qg6+> forces 40...Rxg6 41.Rg6+ Kh7 42.Ng5+ Kh8 43.Nf7+ forks the Queen and White is up a rook |
|
| Jun-03-15 | | jith1207: <BxChess> Just curious, in what scenario, we could opt for gaining material when there is a sure way to mate? |
|
| Jun-03-15 | | Lambda: When the material gain is both more obvious, and good enough. |
|
| Jun-03-15 | | Robespierre: "Oh, good grief!..." Uff-da -- I'm in the same unfortunate boat as Phony Benoni! ;-)) |
|
| Jun-03-15 | | Oxspawn: <goldfarbdj: Qg6+ was the obvious and only move>
Not at all how chess is played on my board. I discarded the 'right' move fairly quickly after concluding that the king could escape! and spent time on 40. Ng5, and 40. Bg6.
OK, so I was wrong, but I was well entertained before starting work. You were right, but you were stuck in the dismal narrow passage of the "only move". Chess as a journey or chess as a destination? And I get to see the correct moves by playing through the game. I see this as a lose-win situation that seems like a win-win solution. Have fun... |

| Jun-03-15 | | bachiller: After 43.Nf7+, Kh7, some people would mate the king. Others would play 44.NxQ; why spoil the fun of playing a few moves in a won game? Checkmate ends it all. Or better, why avoid the exciting possibility of blundering and losing? My choice is 44.NxQ, of course. |
|
| Jun-03-15 | | TheaN: Wednesday 3 June 2015 <40.?> I'm a bit in limbo whether I saw the mate in this one unconsiciously or it all fell into place immediately after opening the game. I saw the obvious <40.Qg6+!> after trying Qxg8, which forces black to walk into a windmill with <40....Rxg6 41.Rxg6+ Kh7> at first sight, white does not get much out of this windmill. However, then you realize the knight's as free as a bird <42.Ng5+ Kh8 43.Nf7+ Kh7>. Now here's the interesting point of this puzzle, and already much discussed. Lets agree that black's lost after either Nxd8 or Rg1-5#, the latter is just quicker and more in line with setting up the combination. By the time I saw that black had no reasonable options left after Nxd8 I clicked the game, but as I did I pondered if white could first use the discovered check; black was losing the queen anyhow. As I played Nf7+ on the board I realized white would checkmate in one and I had the feeling I did <before> I saw the move played on the board or clicking the game. Personally, I'd go with <44.Rg4#> for the reasons <jith1207> posted. Tl;dr, always look for a better move and if black hasn't resigned after Nf7+ you always have time to look for a checkmate. |
|
| Jun-03-15 | | TheaN: What I describe is what I think is also the base of the flawed reasoning of 'overthinking'. We've all had it at least once that immediately when it's your move you know you can't play a certain move because of something. However in overthinking all your options, 'something' is completely forgotten and the initial wrong move is played anyway. An unconcious decision to reinstate the move you discarded earlier. NB: oh and again the Wednesday puzzle seems more forced and in a way easier than Tuesday. |
|
| Jun-03-15 | | dfcx: It's a simple mate in 5.
40. Qg6+ Rxg6 41. Rxg6+ Kh7 42. Ng5+ Kh8 43. Nf7+ Kh7 44. Rg5# I first saw the fork Nf7+ then found the mate.
This is way easier than the last Tuesday's puzzle. |
