  Check It Out: 24.Qxd4 cxd4 25.Bh6# seemed too easy so I came up with 24.Qxd4 Qxf7 25.Qh8+ Qg8 26.Qf6+ Ke8 27.Qe7#.
Oct-07-15  psionl0: I would like to brag about how clever I was to solve this problem in 5 minutes.

However, it took 4 of those minutes to realize that White's King was in check. Once I realized that, the game played itself.

  patzer2: Following a typically easy Monday and Tuesday puzzle, today's Wednesday puzzle solution 24.Qxd4 Qxf7 (24...cxd4 25.Bh6#) 25. Qh8+ Qg8 26. Qf6+ Ke8 27. Qe7# was so simple it felt like Monday came three times in a row this week.

Sort of reminded me of "Ground Hog Day" with Bill Murray.

From https://en.wikiquote.org/wiki/Groun...(film):

"Rita: What about me, Phil? Do you know me too?

Phil: I know all about you. You like producing, but you hope for more than Channel 9 Pittsburgh.

Rita: Well, everyone knows that!

Phil: You like boats, but not the ocean. You go to a lake in summer with your family up in the mountains. There's a long wooden dock and a boathouse with boards missing from the roof, and a place you used to crawl underneath to be alone. You're a sucker for French poetry and rhinestones. You're very generous. You're kind to strangers and children, and when you stand in the snow you look like an angel.

Rita: How are you doing this?

Phil: I told you. I wake up every day, right here, right in Punxsutawney, and it's always February 2nd, and there's nothing I can do about it."

  morfishine: Easy enough, the Bishop can be captured with tempo by the Queen due the mate threat: <24.Qxd4> and now 24...cxd4 is met by 25.Bh6#

No use in "drogging-it-ou" with 24...Qxf7

  patzer2: Black's decisive mistake was <17...Qd8??>, allowing 18. Rxf7+ (+6.53 @ 21 depth, Deep Fritz 14).

Instead, 17...Bd4+! (-1.12 @ 21 depth) holds as play might continue 18. Kh1 f6 19. Bxg5 Kg7 20. Bg4 Rh8 (20... fxg5? 21. Rf7+ =) 21. Bf4 Qe8 22. Qb3 b6 23. Bf5 Nf8 24. Rae1 Nbd7 25. Rxe4 Ne5 26. d6 Nfxg6 27. Qg3 Rd8 28. Bxe5 Bxe5 29. Rxe5 Qxe5 30. Qxg6+ Kf8 31. h3 Rxd6 32. Bd3 Rh4 33. Bc4 Rxc4 34. Qh6+ Ke8 35. Qg6+ Kd7 36. Qf7+ Kd8 37. Qxc4 Qxb2 38. Qf7 a5 39. Re1 Rd7 40. Qg8+ Kc7 (-0.74 @ 22 depth).

  gofer: This one is a simple queen sacrifice, but it has a nice twist, a counter queen sacrifice as a defence!

<24 Qxd4 ...>

24 ... cxd4
25 Bh6#

24 ... Qxd6
25 Qh8#

<24 ... Qxf7>

A valiant try but it fails on many levels; White can try

25 Bh6+ ...

25 ... Ke8/Kg8
26 gxf7+ mating soon

25 ... Qg7
26 Rf1+ mating soon

But the following looks more forcing...

<25 Qh8+ Qg8>
<26 Rf8+ Ke8>
<27 Qxg8+ Kd7>
<28 Qd5 > mating in only a few more...

~~~

Yep...

Oct-07-15  saturn2: In the 24..Qxf7 variation white can soon deliver a mate with the queen on either f7 or e7 because the advanced pawns d6 and g6. The rock is not needed.
Oct-07-15  Cheapo by the Dozen: I didn't bother analyzing it out to mate, once I noticed that

24 Qxd4 Qxf7
25 Bh6+

wins the queen.

I still count that as a success. :)

  Oxspawn: If white were free to choose any move then Bh6 would be mate. But white is in check, so probably a good idea to remove that.

24. Qxd4 seems to do a decent job of this, since if
24. cxd4
25. Bh6 is still mate.
As this is not Monday I suspect that Black has a better defence. Nc6 does not seem to help any and the queen cannot interfere with the black bishop so…

24. Qxd4 Qxf7
25. Qh8+ Qg8
26. Rf1+ Ke8
27. Qxg8+ Kd7
I think black moves 25, 26 and 27 are all forced and the position is hopeless. I cannot see the best continuation without setting up the board, but any of 28. Be7, Qf8 or Re7 would surely lead to a quick win.

Oct-07-15  Robespierre: Refer to the comment from 'psionIO' above. Replace the numbers, 5 & 4, with my numbers, 10 & 9. Thus, he's about twice as astute as I in solving these problems! ;-))

  patzer2: After 24. Qxd4 Qxf7 (diagram below),

the quickest rout to mate is 25. Qh8+ Qg8 26. Qf6+ Ke8 27. Qe7#.

However, a fun option is 25. gxf5 cxd4 (diagram below)

when it's mate-in-three after 26. Rf1! Kg7 (26... Nd7 27. Bh6#) 27. f8=Q+ Kg6 28.Qh6#.

Oct-07-15  Mehem: Generally speaking it would be nice to see puzzles which are "the result changer". In the given position I can play 24.Kh1 and Black are still completely lost.

  agb2002: White has the bishop pair and a pawn for a bishop and a knight.

Black checks and threatens 24... Qxd6.

The obvious move is 24.Qxd4 Qxf7 (24... cxd4 25.Bh6#) 25.Qh8+ Qg8 26.Qf6+ and mate next.

Oct-07-15  schachfuchs: Got that in 10 sec - even considering the mentioned counter queen sacrifice 24.Qxd4 Qxf7 25.Qh8+ Qg8 where I quickly saw Bh6+ is also doing the job.

But the funny thing is: only after reading through the (always appreciated) comments of patzer and psionl0 I realized like him that in the puzzle position White's King was in check! :-)

Oct-07-15  TheTamale: Friends, this is perhaps the first time this year I've successfully solved a Mon/Tue/Wed trilogy. Please forgive my boasting over this admittedly modest accomplishment..
Oct-07-15  abuzic: Only 4 moves are possible:
24.Kf1 loses to 24...Qf5+;
24.Kh1 which eventually wins;
24.Be3 should also win;
and BINGO 24.Qxd4 and Bh6# to follow; if 24...Qxf7 25.Qh8+ mates in 3; a longer range mate is possible with 25.Be7+ Ke3 26.gxf7+ Kd7 27.f8N+ Kc6 28.Qxe4+ Kb5 29.b3 Nc6 30.Qa4+ Kb6 31.Nd7# <on 29...c4 30.Qxb7+ Kc5 <(30...Ka5 31.Bd8#)> 31.Ne6#

  kevin86: Monday type puzzle...the only quirk- black can refuse the queen sac and then must lose his own queen!
Oct-07-15  BOSTER: Beginning from Sunday <CG > have given 3 times <POTD> with advanced white pawn on< d6 >. Maybe this is coincidence, or maybe CG want to show that enough to advance white pawn on <d6 > , and you'll win the game.
Oct-07-15  dark.horse: White's bishop stabs the Black king in the back.
Oct-07-15  PJs Studio: 24.Qxd4! Black misses an excellent chance to resign if he plays 24...Qxf7
Oct-07-15  starry2013: I thought I'd solved this - Be7 as first move. But when I set it up on the computer site I found I couldn't move lol. I was in check. So the problem started all over again for me.

It took a while too, even though I suppose I should have guessed it was a sacrifice despite not being a sacrifice check like often earlier in the week, in fact it's a sacrifice to get out of check.

1. Qxd4 2.Qxf7 gxf7 3.cxd4 Rf1 4.Kg7 f8=Q+ 5.Kh7 Rf7+ 6.Kg6 Qg7+ 7.Kh5 Be7 8.Nc6 Rf5#

  Bubo bubo: 24.Qxd4! parries the check and sets up the dual threat of Qh8# and Bh6#.

Black can avoid instant checkmate only by playing 24...Qxf7. But on 25.Bh6+ the black king has to flee to e8/g8 (or 25...Qg7 26.Qxg7#), causing his queen to drop <with check>. After 25.gxf7+ Kxf7 26.Qg7+ White is simply up a queen and a pawn.

An amusing puzzle! Both queens capture the guarded kingside's bishop in turn, but with quite different results. <Quod licet jovi, non licet bovi.>
