May-31-17  RKnight: Double rook sac and mate! Pretty simple as a problem, but how many of us would see it over the board? Unlikely for me.
May-31-17  goldfarbdj: I got the basic idea, but I got the order of moves wrong: I thought Rd8+ first, which after Qxd8 allows a very similar finish: 25 Rh8+ Bxh8 26 Qh7+ and mate next. But Black can block with 24 ... Bf8, after which the attack, while winning, takes longer.
May-31-17  lost in space: The quickest way to mate seems to be

24. Rh8+ Bxh8 25. Rd8+ Qxd8 26. Qh7+ Kf8 27. Qf7#

but also 24. Rd8+ Bf8 25. Rh8+ Kg7 26. Qh6+ Kf6 is mate soon

May-31-17  poulh: Where is the mate soon after 25. Rh8+ Kg7?
May-31-17  diagonalley: wow! ... easy peasy for a wednesday :-)
May-31-17  BxChess: I found a marvelous forced mate after 24. Rd8+ Bf8 25. Rh8+ Kg7 but this box is too small to contain it.
May-31-17  stst: Almost all Forced ...
24.Rh8+ BxR
25.Rd8+ QxR or Qe8 (if Qf8, 26.Qh7#)
26.Qh7+ Kf8
27.Qf7#
May-31-17  stst: <I found a marvelous forced mate after 24. Rd8+ Bf8 25. Rh8+ Kg7 ..>

Same 26.Qh7+ Kf6, 27.Rf8+ QxR, 28.QxQ and White prevails..

May-31-17  agb2002: White has a rook and a knight for the bishop pair and a pawn.

Black threatens Qxg5.

The knight on g5 and the queen on h3 suggest the possibility of an eventual mate Qh7+ and Qf7# but the black queen controls the seventh rank. Therefore, 24.Rd8+:

A) 24... Qxd8 25.Rh8+ Bxh8 26.Qh7+ Kf8 27.Qf7#.

B) 24... Bf8 25.Rh8+ Kg7 26.Qh6+ Kf6 27.Rf(h)xf8+ Qxf8 28.Rxf8+ Ke7 29.Qg7+ Kd6 30.Rd8+ Bd7 31.Q(R)xd7#.

May-31-17  patzer2: For today's Wednesday puzzle solution (24. ?), we have two decoys leading to mate-in-four after 24. Rh8+! Bxh8 25. Rd8+! Qxd8 26. Qh7+ Kf8 27. Qf7#.

It was so easy, I imagined an experienced hunter in a marsh setting out decoys to successfully attract a flock of ducks. Once the ducks are attracted to the decoys, it's easy for an expert hunter with a shotgun to pick them off.

Seems to me that's roughly analogous to how the two key decoys in this game <24. Rh8+!> and <25. Rd8+!> were used to attact Black's defenders and put the enemy King into position to be taken out with checkmate.

P.S.: Black's decisive mistake appears to be the not-so-obvious 17...exf4? allowing 18. hxg6 to (+2.34 @ 28 depth, Stockfish 8.)

Instead 17...Bxg4! 18. hxg6 hxg6 19. Bh6 Bxf3 20. Qe3 Bxd1 21. Bxg7 Kxg7 22. Qh6+ Kf7 23. Rxd1 Rh8 = (0.00 @ 34 depth, Stockfish 8) holds with level chances, as play might continue 24. Ng5+ Kf6 25. Ne4+ Kf7 25. Ng5+ Kf6 26. Ne4+ Kf7 27. Ng5+ = with a draw by threefold repetition.

May-31-17  AlicesKnight: It looks like a different form of double-rook sacrifice. 24.Rd8+ probably brings ...Qxd8, whereon 25.Rh8+ Bxh8; 26.Qh7+ Kf8; 27.Qf7 mates. In the unlikely event of 24... Bf8, 25.Rh8+ Kg7; 26 Rh7+ wins the Q, or better still 26.Qh7+ Kg6; 27.Rhxf8+ Qxf8; 28.Rxf8 and 'curtains'. Let's see - same 'error' as <goldfarbdj> but OK.
May-31-17  Walter Glattke: "We love Mondays",24.Rd8!?, Knight, then
allows 24.-Bf8 25.Rh8+ Kg7 26.Qh7+ Kf6
or 25.Rxf8+ Qxf8 26.Rh8+ Kg7 27.Qh6+ Kf6
and butcher's Party for Lovers with 28.Rxf8+
May-31-17  lost in space: <<poulh>: Where is the mate soon after 25. Rh8+ Kg7> 24. Rd8+ Bf8 25. Rh8+ Kg7 26. Qh6+ Kf6 27. Rdxf8+ Qxf8 28. Rxf8+ Ke7 29. Rf7+Kd6 30. Qf8#

you too? I thought I am the only one

May-31-17  Walter Glattke: The Bangles and the Boom Town Rats don't like Mondays, but we do this. I just remembered to 1963, we played School chess, and a pupil said to his opposite, he would not set him mete, before, he would take off all his chessmen, then finally mate. I saw, here we can play cruel chess after
24.Rd8.

May-31-17  BxChess: 0 for 3 so far this week. I've got a bad feeling about tomorrows duel.
May-31-17  gofer: Okay, we have <"the hard way or the easy way - which do you want?">.

The easy way...

24 Rh8+ Bxh8
25 Rd8 Qxd8 (Kg7 Qxh8#)
26 Qh7+ Kf8
27 Qf7#

Dummy here, chose the hard way...

24 Rd8+ Bf8 (Qxd8 transposes)
25 Rh8+ Kg7
26 Qh6+ Kf6
27 Rdxf8+ Qxf8
28 Rxf8 Ke7
29 Qg7+ Kd6
30 Rf6+ Be6
31 Rxe6#

May-31-17  saturn2: Black has more material but both 24 Rd8 and 24 Rh8 save the point for white.
May-31-17  leRevenant: <diagonalley: wow! ... easy peasy for a wednesday :-)> Yes, easiest so far, this week.
May-31-17  et1: given the theme of the week this was easy, never 2 without 3... :)
May-31-17  cocker: 24 Rh8+ mates in 4, 24 Rd8+ mates in 7. I went for the slow one.
May-31-17  Moszkowski012273: If black had found 17...Bxg4 he MIGHT of held this game.
May-31-17  morfishine: Both 24.Rd8+ & 24.Rh8+ win

*****

May-31-17  nalinw: <BxChess> I found a marvelous forced mate after 24. Rd8+ Bf8 25. Rh8+ Kg7 but this box is too small to contain it.

Fermat's ghost? I love it!
