| Oct-28-20 | | Stale.Mate: I thought “X to play” means X is going to win. |
|
| Oct-28-20 | | Walter Glattke: Applause to agb, I thought for 36.Qb2 while 36.Nc4? loses by 36.-Qa1+ 37.Qb1 Qxb1+ 38.Kxb1 Nxc4 - 36.-Qxb2+ 37.Kxb2 Rd2 38.Rg6 Rxf2 39.Rxh6 Nxa5+ 40.Kb3 Rf3 41.Kxa4 Rxg3 42.Rxf6 Rh3 43.Rh6? hah- hah 43.-b5+ 44.Ka5 Ra3#, but ending of course rather draw. |
|
| Oct-28-20 | | Cheapo by the Dozen: Black's 36th move was a successful sacrifice. Perhaps that's what the puzzle was meant to be. |
|
| Oct-28-20 | | Walter Glattke: Oh, oh, earlier mate, Rd2 seems to strong in the continuation. |
|
| Oct-28-20 | | Brenin: Very confusing: White to play and avoid a blunder. I spent several minutes wondering why 36 ... Nc4 didn't refute 36 a5, only to find that it does. White threw away a win with 33 Qb3, when 33 Bxb6+ Nxb6 34 Nf5 would have retained a big advantage. In fact, Bxb6+ could have been played at any of moves 30 to 33. |

 | | offramp: <morfishine: Wow, Pomar only passed away 4 years ago.> Yes, he lived to the age of 84, including a 50 year chess career. Towards the end of that career he played Topalov:
Topalov vs A Pomar Salamanca, 1992
And at the start he had played Maroczy:
A Pomar Salamanca vs Maroczy, 1947 Maroczy had played Henry Bird:
Bird vs Maroczy, 1895 And Henry Bird had played Paul Morphy:
Morphy vs Bird, 1858 So that is four handshakes from Morphy to Topalov. |

| Oct-28-20 | | et1: White to play and lose ? |
|
| Oct-28-20 | | erimiro1: 36.-Nc4!! what a shocking move. I also thought that 36.a5? will do, but after the response it's clear that 36.Kb1 is essential. |
|
| Oct-28-20 | | Willem Wallekers: Black is threatening Nc4. What can I do? Give check with Ra8+? Otb I would play Kb1. Now let's open the link for the real solution. |
|
| Oct-28-20 | | Everett: I often solve for both White and Black to move. Proved very helpful in this case |
|
| Oct-28-20 | | beenthere240: Us chess championship now being played. GAS CG? |
|
| Oct-28-20 | | TheaN: After looking at White to play for about five minutes, I deduced this was supposed to be <Black to play>; not knowing whether this was the position after B35 or W36 I solved it anyway, given that 36.a5 doesn't change the position tactically. I saw 36.a5 <Nc4!> given Black threatens Qa1-a3-b2#. 37.Qxc4 Qa1# doesn't make this any better, and after 37.Nxc4 the mate's gone but Black follows 37....Qa1+ 38.Qb1 Rd1+ -+. The move I was not sure about (but given I was already solving it in the wrong position and deducing the correct color, so I'm happy as is) was <37.Qa2>. I thought Black's best was <37....Nxe3> threatening Rd1# to boot <38.fxe3 Qxe3+ 39.Kb2> but here I was struggling a bit to finish it off:

I had the feeling Black's a lot better and probably has to continue with <39....Qe5+ -+>. The key is limited space for the king. The 'simple' variations are 40.Kb1 Rd1#, 40.c3 Rd2+ -+ and 40.Kc1 Qe1+ 41.Kb2 Qxb4 -+. The second hardest line (and we're already a few moves in) is 40.Ka3 Rd1! -+, essentially trapping the queen. The hardest line, by far, is <40.Kb3>:

Where you'd have to find <40....c5! -+> just before time control to snare the king. Even given the mishap with the color to play, the 37.Qa2 variation goes a bit too far for a Wednesday I'd say; that's if it's not enough to claim Black's better after 37....Nxe3 38.fxe3 Qxe3+. |
|
| Oct-28-20 | | gym: By Stockfish10 36.Qa3 leads to a draw. |
|
| Oct-28-20 | | Predrag3141: The error in puzzle positions seems to occur in one place where a human enters the wrong move number, from which the server generates a matching (but incorrect) caption and URL. Here as in a recent case where the move number was after the end of the game, the caption and URL match. |
|
| Oct-28-20 | | SpiritedReposte: Ah the old white to move and blunder puzzle. I was born for these. I like my solution better. <Qc3??> |
|
| Oct-28-20 | | Pawn Slayer: Brilliant. An hour of analysis and I found no win for white.
Then I noticed that black wins.
That's an hour of my life I won't get back. |

 | | benveniste: White to play and avoid a5. I came up with ♖g4, which I think invites the quickest draw. |
|
| Oct-28-20 | | thegoodanarchist: Unfortunately, I found the same solution Nona found. |
|
Oct-28-20
 | | paulalbert: Glad I did not spend more time on this agonizing over why I was too stupid to find a forced win for White.The tempting a5 did not seem to work and Qa3 or Kb1 seemed necessary to protect the a1 square from a1 Black Q check, but did not seem to threaten Black. |
|
| Oct-28-20 | | Messiah: Terrible! |
|
| Oct-28-20 | | Walter Glattke: What we can learn: stockfish is better than Gaprindashwili, but we knew this before! |
|
Oct-28-20
 | | OhioChessFan: Come on, people. White to play. Find the best move, <regardless of whether the game follows that line>. Loike, what a bunch of pearl clutchers here. |

 | | FSR: <offramp> I drew Leonard Barden. L Barden vs F Rhine, 2010. Barden drew Mieses at the Hastings Premier Reserves 1948-49. Mieses drew Bird in the last round at Hastings 1895. Bird vs J Mieses, 1895. Bird lost five games to Morphy in 1858 and 1859. https://www.chessgames.com/perl/che...
Indeed, as I documented in Wikipedia, Barden has a Morphy number of three by six different routes, more than any other living player. https://en.wikipedia.org/wiki/Leona... |
