38. Rh8+ Nxh8 39. Qg7#
|Apr-10-12|| ||LoveThatJoker: Sunday, April 8th, 2012
I'm going to divide my solution into two sections (i.e., 'Accepted' and 'Declined') so as to make it more inviting than a large jumble of variations would
The solution starts with <14. Nxh7>
<14. Nxh7 Kxh7 15. Qh5+ Kg8 16. f5>
a) 16...d6? 17. Bg5 Qf7 (17...Qd7 18. Bxe6+ wins) 18. fxe6! Qxh5 19. e7+
b) 16...Ne5 17. Bb3 Nf7 [17...Nc6 18. fxe6 d6 (18...d5 19. Bxd5 wins at least a pawn; 18...dxe6 19. Bc5 wins) 19. Rf7 and White has evened up the force count and has a strong attack] 18. fxe6 dxe6 19. Rf3 with the two Bishops and the strong and flexible plan of doubling on either the f- and h-files with a positional advantage.
c) 16...Na5 17. Bxe6+ dxe6 18. f6 Rxf6 (18...gxf6 19. Bc5 Qf7 20. Qg4+ Qg7 21. Qxg7+ Kxg7 22. Bxf8+ Kxf8 23. Rxf6+ and now despite that White has only a R+P for 2 minors, he does have the strong and connected kingside passers, plus better piece activity) 19. Qxa5 to as Black cannot easily develop his Queenside. This said this variation as well as variation 'b' above seems to be Black's best defense.
a) 14...Rf5 (preventing 15. Qh5) 15. Bd3 and White keeps his pawn with an excellent attacking position.
b) 14...Nxf4 15. Bxf4 Qc5+ (15...Rxf4 16. Rxf4 Qe3+ 17. Rf2 ) 16. Kh1
c) 14...Nd8 15. Nxf8! Qxe3+ 16. Kh1 Qe8 17. Qg4! and the N is saved as both 17...Qxf8?? 18. Qh5#; while 17...d5 18. Ng6+ win for White.
d) 14...Ng5 15. Nxf8 Qxe3+ 16. Kh1
e) 14...d5 15. Nxf8 Nxf8 16. Qh5+ Nh7 17. Bd3 Qxe3 (17...g6 18. Bxg6 Qxe3+ 19. Kh1 Qe7 20. Rae1 wins) 18. Kh1 Kg8 19. Bxh7+ Kf8 20 Rae1
|Apr-10-12|| ||LoveThatJoker: Saturday, April 7th, 2012
a) 28...Rxh5 29. Nxg6+ hxg6 (forced as 29...Kmoves 30. Ne7+ wins) 30. Rxg6 Rxh2+ 31. Qxh2+ Rh7 32. Rh5! Qd7 33. Rxh7+ Qxh7 34. Rh3
b) 28...gxh5 29. Rg8+ mating
c) 28...Rg7 29. Bxg6 hxg6 (29...Kg8 30. Bf7+ wins) 30. Nxg6+ Rgxg6 (30...Kh7 31. Nf8+ ; 30...Kg8 31. Ne7+ ) 31. Rxg6 Rxg6 32. Rxg6 wins
d) 28...Kg8 29. Nxg6! hxg6 [29...Kh7/...Rg7 30. Ne7+ wins; 29...Kf7 30. Ne5+! Kf6 (30...Ke7 31. Rg7+ Kf6 32. R7g6+ transposes) 31. Rg6+! hxg6 32. Rg6+ Rxg6 (32...Ke7 33. Rxh6 ) 33. Qxg6+ Ke7 34. Qg5+ Kf8 35. Qf6+ Kg8 36. Bf7+ Rxf7 (36...Kh7 37. Qg6+ Kh8 38. Qh6#) 37. Qxf7+ Kh8 38. Ng6#] 30. Bxg6 wins
e) 28...Kg7! (surprisingly the best try) 29. Nxg6! hxg6 30. Bxg6 Qh8 [30...Kf8 31. Bxf5 ; 30...Kf6 31. Bh5 Rah7 (31...Rxh5 32. Rxh5 ; 31...Qh8 32. Rg6+ Rxg6 33. Rxg6+ Ke7 34. Rg7+ Kf8 35. Rxa7 ) 32. Rg7! Rxg7 33. Rxg7 e5 34. Qg5+ Ke6 35. Bf7+ Kd7 36. Ba2+ Ke8 37. Qe7#] 31. Bxf5+ Kf6 [31...Kf8 32. Rg8+ ; 31...Kf7 32. Rg7+ Kf6 33. R3g6+ Kxf5 (33...Rxg6 34. Qxg6#) 34. Qg5+ Ke4 35. Qe5#] 32. Rg6+ Rxg6 [32...Kxf5 33. R3g5+ Ke4 (33...Kxf4 34. Qg3+ Ke4 35. Qf3+ Kxd4 36. Qd3#) 34. Qb1+ Kxf4 (34...Kxd4 35. Qd3#; 34...Ke3 35. Qd3+ mating) 35. Rg4+ Ke3 36. Qd3+ mating] 33. Rxg6+ Kxf5 [33...Ke7 34. Qg5+ wins; 33...Kf7 34. Bxe6+ Ke7 (34...Kf8/...Ke8 35. Rg8+ wins) 35. Qg5+ wins] 34. Qb1+ Kxf4 35. Qd3! Qh5 (forced) 36. e3+ Kf3 37. Rg3+ Kf2 38. Qd2+ Qe2 (forced) 39. Rg2+ Kf3 40. Qxe2+ wins
|Apr-10-12|| ||VincentL: "Easy".
Perhaps this is rook sacrifice week.
Here 42. Rh8+ ! ends the game, since after 42.....Kxh8 (forced) 43.Kg6 and black cannot prevent Re8# (Re2 / Be5 delay the inevitable).
|Apr-10-12|| ||gawain: My first thought was Rh6+ which does mate but only if Black captures the rook. But Black can refuse. Therefore 42 Rh8+ Kxh8 (forced) 43 Kg6 and Black can do nothing to prevent 44 Re8#.|
|Apr-10-12|| ||gawain: <Vincenti> is right. Black can delay--but not prevent--the eventual Re8#|
Maybe every solution this week will begin with Rh8.
|Apr-10-12|| ||tcoxon39: 42. Rh8+ Kxh8 43. Kg6 ... 44. Re8#
Black can postpone the mate for a couple of moves, but it is futile.
|Apr-10-12|| ||bachbeet: Got it. Again, easier than past Tuesday puzzles.|
|Apr-10-12|| ||sleepyirv: First we sac the rook but which rook? Rh6+ would lead to a pretty mate if Black forgot how pawns capture but since we cannot count on our opponent's ignorance...
42. Rh8+ Rxh8 43. Kg6 Rxf2 44. Re8+ Rf8 45. Rf8#
43. Kg6 is a minor quiet move and I would like to drill chessgames.com drilled into my thick skull that not all moves have to flashy threats with these puzzles.
|Apr-10-12|| ||Marmot PFL: Not too difficult, but 42 Rh8+ wasn't the first move I looked at (maybe the 3rd). After 43 Kg6 black is incarcerated without any chance of parole.|
|Apr-10-12|| ||M.Hassan: "Easy" White to play 42.?
White has a Rook+pawn for a Bishop

What can Black do to prevent mate by Rook moving to e8?. Delay the inevitable:
|Apr-10-12|| ||Whitehat1963: Saw this one right away, unlike Monday's (in which I reflexively looked no further than a queen sac and missed!)|
|Apr-10-12|| ||WinKing: A cute finish.
Black could throw in a few spite blocking moves here to prevent the mate with but I would think that he resigned. Let's see.
|Apr-10-12|| ||mohannagappan: 42 Rh8+ Kxh8 43 Kg6 Black cannot escape from mate|
|Apr-10-12|| ||dzechiel: White to move (42?). White is up an exchange and spawn "Easy".|
White ends this game quickly with...
42 Rh8+ Kxh8 43 Kg6
Black can make any move here, but there's no stopping...
|Apr-10-12|| ||sevenseaman: White is a P and an exchange better.
1) Deliver a R check at h8 before it is too late.
2). Double the Rs on the 8th.
42. Rh8+ Kxh8 43. Kg6 is a polished (Chess Tempo type) win, a tactical shot. It leaves no resource to Black against the threatened 44. Re8#.
Its a win win for White though.
I do believe he would win in a pedestrian manner too.
42. Ree8 g5+ 43. Kg5
(Now the White threat has shifted to 44. Rd7# & Black is in an emergency situation).
Any B check by Black ends up losing him his B.
i) 43...Bd2+ 44. f4 Bxf4+ 45. Kxf4
ii) 43...Bf6+ 44. Kxf6
I do not think a perpetual is possible.
Memories of my yesterday's faux pas will rankle long. It looks I was the only one to put my foot in my mouth.
|Apr-10-12|| ||FSR: This one actually took me a few minutes. I started out looking at 42.Rh6+?? (a "fifty-percenter," hoping for 42...Kxh6?? 43.Rh8#) gxh6 and wins, and tried to figure out how to make 42.Ree8? work. I should've also looked at the other check immediately. 42.Rh8+! Kxh8 43.Kg6 followed by back-rank mate.|
|Apr-10-12|| ||M.Hassan: |

Black to move and win.
I could'nt do it without getting help. I am sure many kibitzers can.
|Apr-10-12|| ||DrywallRickshaw: <Hassan>, is it... 1. ... Ng3+ 2. hxg3 3. Rf6!
And if Rxf2, then ...exf2 and mate is unavoidable. In fact, if anything at all, mate is unavoidable I believe.|
|Apr-10-12|| ||M.Hassan: <DrywallRickshaw>:
|Apr-10-12|| ||MarkFinan: This took me a minute or two to see, and i even looked at Rh6? first, but hands up if you think you'd have seen this in tournament play?? Or any OTB game??|
I only solved this as it's a puzzle, i wouldn't have seen it otherwise..
|Apr-10-12|| ||FSR: <sevenseaman: ... I do believe he would win in a pedestrian manner too.|
42. Ree8 g5+>
<Not> forced. 42...Rxf2+ is much better. But I do congratulate you for figuring out how to make the "box" symbol - the square. How did you do that?
|Apr-10-12|| ||Once: <M.Hassan> I had answered your copy and paste question two days ago, when you first asked it...|
It's worth checking back on old posts, especially those where you ask a question ;-)
|Apr-10-12|| ||rhickma4: I don't think I have seen a mating pattern like this before.|
42.Rh8+ Kxh8 43.Kg6
Blacks pieces a strangely helpless to stop the back rank mate.
