  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.

  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.

  playground player: Odin downs Beer?
Dec-16-15  jwjennings: Dec-16-15 zluria: The game continuation is pretty and forcing, but doesn't the simple Rh6 threatening Rh8++ also win?

Opps 25... d5-d4

Dec-16-15  dfcx: There are several choices for white. Rxh6 and Bh7+.

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

With 25.Rxh6, black's only defense is 25...Qxb2+ 26.Qxb2 Rxb2 27.Kxb2 Kxg7 and white has won a rook for two pawns. Wait I just saw <jwjennings: ... Opps 25... d5-d4>

Dec-16-15  Marmot PFL: Found this instantly...yesterday I lost a winning game in time trouble by overlooking exactly this bishop check.
Dec-16-15  Coriolis: Did anyone see a phantom clue (possibly clue 21) yesterday (depending on time zone maybe) that vanished and was replaced?

  morfishine: <Marmot PFL> Yesterday, I crushed my opponent but 'mouse-slipped' and stale mated

What is one to do?

  Sally Simpson: Hi Morf.

(Mouse slips) "What is one to do."

Look at what you have done and turn it into a swindle. A while back I was Black in an online blitz game.


click for larger view

I played 1...Ka5 2.Rb1 a2 3.Rxb5+


click for larger view

Here I moved my mouse clicked on the screen intending 3...Ka4 which draws but it jumped/slipped and I played 3...Ka6.


click for larger view

My opponent played 4.Ra8 and I suddenly saw 4...Ka7.

and I'm winning and actually did win. If not for the mouse slip I'd have played 4...Ka4 which draws or I may have resigned because if it had gone as I intended.

4...Ka4 5.Rb8 Ka3.

My opponent may have been one of them that would have gone Ra8+ & Rb8+ till a my flags drops. I repeat for a few times and resign these games. I don't get involved in that silly nonsense.

Dec-16-15  1.e4effort: For me, this was the easiest Wednesday puzzle ever - white had to check and keep checking or it was over.
Dec-16-15  Sniffles: Too many people are thinking game play instead of blitz. Blitz dictates a check and there is only one. At that point the puzzle becomes <1 difficulty. If the puzzle started at 25, K on H7 the play is obvious. You can add to this in that the Bishop must be moved or the Queen gets forced out of her position with h5.

  Penguincw: Ooh, almost end of day, and I still haven't attempt the puzzle!

Anyway, I had 2 thoughts: 25.Rxh6 Qa1+ 26.Kd2 f6 27.Rh8+ Kf7 28.Bg6+ Kxg6 29.g8=Q+, etc (not going to mention any errors in this line)

I also considered 25.Bh7+ Kxh7.

Dec-17-15  Sniffles: <Penguincw> 25.Rxh6 d4 sinks the boat.

  morfishine: <Sally Simpson> Now that is funny! Maybe it wasn't a "mouse slip" after all, but your "inner self" or intuition took over since it knew the winning line and magically forced Ka6

Nice win!

My gaffe was the truest mouse-slip possible:

Here, I meant to play Rf6 but the Rook slipped sideways to <e7>. Was I Nervouos? Sweaty? I didn't care to ponder these excuses as I rushed to the fridge for a fresh beer, muttering under my breath LOL

  TheFocus: I wish I could blame my OTB losses on a mouse-slip.

  kevin86: The double sac sends the black king down a black corridor where he is mated by the other rook.
