Jul-29-18  messachess: Why the Sunday puzzle when the first two moves are so easy?

  al wazir: I found 39. Rxd5 exd5 40. e6, but I was unsure of the continuation, because I didn't know what black would play.

Fortunately, Zhigalko resigned and saved me the trouble.

  agb2002: Recycled.
Jul-29-18  Walter Glattke: 39.Rxd5 exd5 40.e6 Rf8 41.Bxc6+ Qxc6 42.Qxf8 (>e7) Qxe6 43.Qxg7+ (sudden mating) Kc6 44.Qc7+ Kb5 45.b7 Qc6 46.b8Q+ or 45.-Bxb7 46.Qxb7+ Kc5 47.Bd4#
The harmless looking Qg7+ decides the match then.
Jul-29-18  Granny O Doul: I hadn't seen this since June, but I still knew it was from a game of chess.
Jul-29-18  morfishine: Seen this one <39.Rxd5> followed by <40.e6>
Jul-29-18  Cheapo by the Dozen: I completely forgot we'd seen this not long ago -- but yeah, it was pretty easy. I saw Rxd5 immediately, but looked at other followups first before hitting on e6.
Jul-29-18  wrap99: I saw this in seconds, like less then 10 seconds. I attribute this to many hours at Bughouse chess.

  malt: 39.R:d5 ed5 40.e6 Rf8

(40...Re7 41.B:c6+ Q:c6 42.Q:e7+ )
(40...Rf6 41.B:f6 )

41.B:c6+ Q:c6 42.Qe7+ Kc8 42.Q:f8+

Jul-29-18  Absentee: <wrap99: I saw this in seconds, like less then 10 seconds. I attribute this to many hours at Bughouse chess.>

Me too, but I attribute it to the puzzle being much easier than the Sunday average.

Jul-29-18  wrap99: <Absentee>: Sure, but I have to say that BH, which has a bad reputation among serious players often, seems to help certain areas of chess, at least for me. I think playing a lot of BH before a chess tournament is probably a bad idea but BH associated with studying standard chess seems to be useful.

  Dionysius1: I saw it right through to 40.e6 1-0, so I think I'm obliged to claim it as my first ever Sunday win.

I've no "concrete" solution after 40. e6 but black resigns, so there we are.

I expect there are lots of people like me on this puzzle today. Anyone want to argue seeing it through to the opponent resigning isn't enough for us to claim we solved it?

If I ask nicely?

  catlover: <ChessHigherCat: Yeah, it was easy for a Sunday but we got our real Sunday puzzles on Thursday and Friday! Don't you think they were unusually hard?>

Yes, the puzzles on Thursday and Friday seemed unusually difficult.

Jul-29-18  saturn2: 40..Rf6 or 40..Rf8 lose.

40..Rf6 41 BxR gxB 42 BxN QxB 43 QxQ KxQ 44 e7 and neither king nor bishop can control the square e8

40..Rf8 the rook will fall. Black has to give the queen in order to prevent e8Q

Jul-29-18  PJs Studio: I actually got this instantly. But... not sure Iíd have the cajones to play Rxd5 OTB!
Jul-29-18  PJs Studio: Not too tough. Rf7 has no available squares except for e7 which allows Bxc6 and Qxe7.

So, more of a Wednesday puzzle than a Sunday. 😬

Jul-29-18  PJs Studio: I like 14.Rxb4! quite a bit.

  Breunor: I've been on this website for over a decade, I doubt I've gotten more than 5 Sunday puzzles (where I really got it with all variations.) But I got this one easily - it just doesn't seem to be close to Sunday for me.

  PawnSac: < saturn2: 40..Rf6 or 40..Rf8 lose.

40..Rf6 41 BxR gxB 42 BxN QxB 43 QxQ KxQ 44 e7 and neither king nor bishop can control the square e8

40..Rf8 the rook will fall. Black has to give the queen in order to prevent e8Q >

In your line 40..Rf6 41 BxR gxB 42 BxN QxB 43 QxQ KxQ (the K is now on c6, so after..) 44 e7 Kd7 and the K stops the pawn. The correct way to play it is.. ..Rf6 41. Bxf6 gxf6 and 42. e7! immediately as Nxe7?? QxN+ K-any Qa7# so black is at a loss for a move 42... ? . If say ..Qe8 then we have the trade on c6 again but this time the pawn is one square closer to promoting and can't be stopped. If instead of ..Qe8 black plays something silly like Nxa5? then e8=Q Qxe8 Qc7+ Ka8 Qa7#

on ..Rf8 41. Bxc6+ Qxc6 42. Qe7+ Kc8 43. Qxf8+ Kb7 44. Qe7+ Kc8 45. Be5! (white now threatens Qf8+ Kb7 Qb8#, so..) ..Bb5 (to answer Qf8+ with ..Qe8 blocking, but.. ) 46. b7+! Qxb7 47. Qf8+ Be8 48. Qxe8#

Jul-29-18  Mayankk: Like many others, I can claim a rare Sunday solution as well. So what if itís not Sunday material!

Things to notice are

1) All white pieces are involved in the attack except the d1 Rook. If there is a larger material gain possible, like Queening a pawn or mate threats, this Rook can be sacrificed.

2) The c6 knight canít really defend anything as Bxc6+ will render the piece defenceless. So holds true for the c8 Queen since it will have to come to c6 to capture back.

3) Rxd5 followed by an e5 pawn push gives us a passed pawn, threatens the enemy Rook with no pieces to defend it and no hiding place, while also giving our c3 Bishop a long diagonal.

Given all the above considerations, Rxd5 calls itself to be played.
