| Sep-25-18 | | Whitehat1963: Now that’s a Monday/Tuesday puzzle! |
|
| Sep-25-18 | | Matloc: 22. cxd4?
Black bishop is a pain, you can get rid of it with check, so why not?31. Rh6??
Looking for trouble. White king is in cage, the knights out of the battle, one undefended rook left alone to guard last rank. If 31..Qa4, White loses. White attack is a joke. |

| Sep-25-18 | | zb2cr: Very straightforward. 42. Rxh7+ starts things. The main line is 42. ... Kxh7; 43. Qxg6+, Kh8; 44. Rh1+, Rh3; 45. Rxh3+, Qxh3; 46. Nxh3 and White wins on the basis of being ahead by Q+2N vs. R+P. |
|
| Sep-25-18 | | Cheapo by the Dozen: I saw that 44 Rhi+ won massive amounts of material, and stopped there without also noticing the Rg1 mating idea. |

| Sep-25-18 | | patzer2: Sometimes, chess clichés can be helpful. Looking at today's Tuesday puzzle (42. ?), I remembered "always check it might be mate" and "examine every possible check and capture." So I did. First I looked at the exchange captures 42. Nxg6 hxg6 43. Rxd4 Qxd4 44. Qb7+ +- (+10.38 @ 33 ply, Stockfish 9). Although 42. Nxg6 +- simplifies to a piece up winning position, I remembered yet another chess cliché. "If you find a good move look for a better one." So for my second candidate move, I looked at the check 42. Rh7+! and calculated 42...Kxh7 43 Qxg6+ Kh8 44. Rh1+ +- (mate-in-four, Stockfish 9 @ 79 ply) for a faster and easier win. P.S.: So where did Black go wrong?
In this game, Black blew a won position. After 31. Rh6 +-, Black played 31...Qb7? which allows 32. g6! = (+0.08 @ 31 ply, Stockfish 9) to let White off the hook with a level position. Instead 31...Qa4! -+ (-18.80 @ 26 ply, Stockfish 9) with numerous decisive threats, such as 31...Qa4 32. Re1 Bxa2+ 33. Kxa2 bxa3 -+ (mate-in-ten, Stockfish 9 @ 41 ply), would have kept Black on the winning track. |

 | | perfidious: White has more than one way to close the show, but 42.Rxh7+ looks brutally direct and gets the job done. |

<42.?>
Long gone from CG, want to start picking up my daily routine of these puzzles, considering I'm getting a bit tired of Chess.com's easy puzzles or studies. The reason I made this one my maiden flight after an absence of almost 8 months (in practice three years as I've only posted six times since 2015) is that I find the effectiveness of the most logical followup to be intriguing. <42.Rxh7+ Kxh7 43.Qxg6+ Kh8> is obvious. Black can attempt all sorts of declines on move 42, but it's 'LUaE' for White, not Black: <42....Kg8 43.Qxg6+ Kf8 44.Qf6+<>> and mate, <42....Kf8 43.Nxg6+ Ke8 (Kg8 44.Ne7+! Kxh7 45.Qg6+ Kh8 46.Qg8#) 44.Qa8+! Qd8 45.Rf1!!<>> seems painful enough and last but not least <42....Kf6 43.Qxg6+ Ke5 44.Rh5+!<>> makes a decent mating net. What is interesting is what is best after 43...Kxh8. Pretty much everyone so far posts <44.Rh1+<>>. The most logical move, however, what is the follow up after <44....Rh3<>>? <45.Rxh3+?! Qxh3 46.Nxh3<>> and Black isn't mated yet, even though it will follow soon. Paramount is 46....d2 47.Ng5! with mate to follow but Black can postpone it a bit with another move 46. Of course White could play <45.Nxh3?!<>>, but after 45....Rh4 mate's still away, even more than in the beginning. Not doing Rh1+, <44.Qh6+! Kg8 (Qh7 45.Qf8+ Qg8 46.Rh1 Rh3 47.Rxh3#) 45.Rg1+<>> Black can only postpone by interposing <45....Rg3 46.Rxg3+ Qg4 47.Rxg4+ Kf7 48.Qd6+ Kf8 49.Rg8#<>>. This is forced, yet takes to move 49 so it isn't necessarily faster than the first variation. So what is, then? Not sure about what of the above is fastest, I decided to let Stockfish have a go after 43....Kh8. The interesting thing about computers is that they can be so 'cruel', as the computer denotes <44.Rg1> as mate in four. Would any of us play that? Probably not. |

|
| Sep-25-18 | | Strelets: 42.Rxh7+ grills Weber like Cretan apaki. Mate or decisive loss of material is impossible to avoid. |

| Sep-25-18 | | Walter Glattke: Also win with 42.Nxg6 hxg6 43.Rxd4 Qxd4 44.Qb7+ mating or 42.-Rxh4 43.Nxh4+ Kf7 44.Rf1+ or 42.-Re2 43.Rxh7+ Kf6!? 44.Qf3+ |

<Also win with 42.Nxg6 hxg6 43.Rxd4 Qxd4 44.Qb7+ mating> After the above, I don't see any quick mate after, say, 44...Kh6. (Although I do agree that White looks winning.) |

| Oct-02-18 | | PeterPringle: Is this a repeat? I recognized it right away. |

| Oct-02-18 | | Marmot PFL: Much easier than the problem they had up earlier today (Seirawan-Lobron). |

 | | takebackok: Take a break no think Monday, after 42. Rxh7+ it's over. |
|
| Feb-10-25 | | King.Arthur.Brazil: Welcome Mondays: 42. Rxh7+ Kxh7 43. Qxg6+ Kh8 44. Rh1+... |
|
| Feb-10-25 | | saturn2: Rxh7, Qxg6 then Rh1+ |
|
| Feb-10-25 | | mel gibson: That's too easy - LOL. |

 | | Teyss: Yes at last a real <Very Easy> Monday. I thought that if 42...Kg8 or Kf8 or Kf6, White just wins the BQ with 43.Rxd7 but actually it's mate in 3 or 5. |
|
| Feb-10-25 | | TheaN: Holy *bleep* I forgot that wall of text I made in 2018: I Stavrianakis vs U Weber, 2008. Not really sure in what state of mind I was then but it can't be good /s. Because honestly, after <42.Rxh7+ Kxh7 (Kg8/Kf6 43.Qxg6+ +-; Kf8 43.Nxg6+ +-) 43.Qxg6+ Kh8> there's very little that doesn't win for White. Okay, not literally every move, bringing the rook in or shifting the king all work, but no need to over-analyze: this time I saw <44.Rh1+?! Rh3 45.Rxh3+ Qxh3 46.Nxh3 +-> and no reason for Black to continue as it's ♕♘♘:♖, the d-pawn is harmless. |
