  Phony Benoni: First sac a bishop, then sac a rook. Almost the same as saccing a queen.
Dec-16-15  zluria: The game continuation is pretty and forcing, but doesn't the simple Rh6 threatening Rh8++ also win?
Dec-16-15  greed and death: Looks like its something like 25. Bh7+ Kxh7 26. Rxh6+ Kxh6 27. Rh1+ Kg6 28. Rh8 and White queens the g-pawn.
Dec-16-15  greed and death: ...and it looks like i was wrong and 27. Qf6+ leads to mate while my computer says that Rh1+ completely blows the advantage. :P

  Gregor Samsa Mendel: Always seek the most forcing continuation: after 26 Rh6+ Kxh6, follow up with 27 Qf6+ Kh7 (....Kh5 28 Qg5#) 28 Rh1+ Kg8 29 Rh8#.
Dec-16-15  diagonalley: maybe it was an inferior choice, but i thought the obvious, prosaic 25.RxP was winning...

  An Englishman: Good Evening: 25.Rxh6,d4 gives Black defensive chances, but I went with 25.Qf6, second best at best, but possibly also a winner in the long run.

As for a game title, how about "O. B. V. Kenobi?"

  agb2002: The material is identical.

White can deliver mate in five at most with 25.Bh7+ Kxh7 26.Rxh6+ Kxh6 (26... Kg8 27.Rh8#) 27.Qf6+ Kh7 (27... Kh5 28.Qg5#) 28.Rh1+ Kg8 29.Rh8#.

Dec-16-15  Moonwalker: At first I was going to lead with Rxh6 threatening a back rank mate but wasn't comfortable with black's options (creating luft or countering with his queen-rook combo) so looked for something more forceful. Bishop sac THEN Rxh6+ was obvious enough, but then came the second decision point, how to continue the forcing line? Both Rh1+ and Qf6+ looked equally forcing. OTB I probably would have seen it instantly but solving without a board it took a little mental gymnastics but eventually saw that the queen check is superior as it forces mate whether the black king retreats or advances.

  morfishine: Sac, Sac mate: <25.Bh7+> forces the walk of death: 25...Kxh7 then <26.Rxh6+> forcing 26...Kxh6 and finally: 27.Qf6+ etc., etc...

*****

Dec-16-15  BxChess: <zluria>: The problem with 25. Rxh6 is 25...Qxb2+. After the exchnage of queens the pg7 is no longer protected and there is no immediate mate.
Dec-16-15  saturn2: Bh7 Rh6 Qf6 everything with check kills blacks king.

  Once: A neat little puzzle. The trick is seeing that after 25. Bh7+ Kxh7 26. Rxh6+ Kxh6 we need to continue with 27. Qf6+ instead of 27. Rh1+
Dec-16-15  kubbybulin: Missed again. Looked at 25. Bh7 and 26. Rh6 but 27. Rh1 goes nowhere (missing the obvious 27. Qf6). So what do I go for? 25. Qf6 of course. But after 25...Qb2 white is up an exchange but I don't know that black can't hold.
Dec-16-15  Sularus: Didn't see the Qf6+ move.

  patzer2: Got this Wednesday puzzle solution 25. Bh7+, but first had to invalidate 25. Bh7+ Kxh7 26. Rxh6+ Kxh6 27. Rh1+? = (0.00 @ 29 depth, Deep Fritz 14).

Instead, 25. Bh7+ Kxh7 26. Rxh6+ Kxh6 27. Qf6+ completes mate-in-five as posted by <agb2002>.

Black's decisive mistake was 20...Qd4?, allowing 21. g5! (+ 2.74 @ 24 depth, Deep Fritz 14).

Instead, 20...Qc6 (+0.33 @ 24 depth) keeps Black in the fight.

Earlier, Fritz indicates Black missed a potential winning shot. Instead of the tempting 16...Nh5!?, which threatens 17. gxh5?? Bg5 , Black could have secured a strong and near winning advantage with 16... Bb7! when Fritz indicates play might continue 17. h4 d4 18. Ne4 Bxe4 19. Bxe4 e5 20. Qf5 g6 21. Qxe5 Qxe5 22. Bxe5 Nxe4 23. Bxd4 Rae8 24. Rde1 Bd8 25. Re2 Nf6 26. Rxe8 Rxe8 (-2.12 @ 23 depth, Deep Fritz 14).

Dec-16-15  stacase: <Sularus: Didn't see the Qf6+ move.> Sort of like I didn't see the right moves for both the Monday and Tuesday editions. But I did today (-: So I'm of the opinion that this was easy for a Wednesday.

Yes, Qf5+ is the killer move that allows her royal highness to chew up the North East corner of the board in style.

  gofer: A simple "known" mate in 5...

<25 Bh7+ Kxh7>
<26 Rxh6+ Kxh6+> (Kg8 Rh8#)

<27 Qf6+ Kh7> (Kh5 Qg5#)

<28 Rh1+ Kg8>
<29 Rg8#>

  The Long Diagonal: Always check, it can be a mate.

The end of this game reminded me of those blitz games where your opponent is threatening a mate in one and you have no defence, but your opponent only has 5 seconds in the clock and you have two or three spite checks left. So, you just play the checks and throw away all your pieces which are able to deliver a check, using them like kamikaze pilots, hoping that your opponent will flag before he can finish the mating move.

  jith1207: Throw everything [including your kitchen sink and your least favorite pet's food bowl🍜] until the opponent king gets forced to mate.

  jith1207: If Rh6 was played initially, Black would rather not go for Qxb2+ immediately as that could lose a major piece but would go for first rank check to drive the king off the pawn support and then play Qxb2 to exchange the Queens off the board and let the black king capture the pawn from promotion.

It needs to be seen more how that line would play out to the end and who would actually win. Please let us know if you have gone through that alternate line :)

  DuaneTiemann: <jith1207> after Qxb2, Rh8 instead of exchanging queens is mate.

  CHESSTTCAMPS: Material is even and both sides have attacks on the opposing king, but white's is substantially more developed, and black's castled position more substantially weakened. Black threatens both 25... d4 and 25... Qa1+ 26.Kd2 Qxb2. White can avoid counter-play by executing a forced mate:

25.Bh7+! Kxh7 26.Rxh6+! Kxh6 (Kg8 27.Rh8#) 27.Qf6+ Kh7 (Kh5 28.Qg5#) 28.Rh1+ Kg8 29.Rh1+

  CHESSTTCAMPS: Hmm. Rh1+ looked so strong I thought I'd repeat it. Let's try 29.Rh8#

  Machado: Solved today's puzzle after seeing 27.Qf6+ instead of Rh1+. I think the straight 25.Qf6 should win at least a rook.
