Oct-05-20  Brenin: This was a little harder than most Monday puzzles, no doubt because the mate by Qh8 doesn't look likely at first glance. After some rather mediocre defence, Black's final mistakes were 27 ... Re7 (move the B to release the R on a8) and 30 ... Rc7, when Qe6 would have slowed down White's attack.
Oct-05-20  stacase: <Brenin ... the mate by Qh8 doesn't look likely at first glance.>

I spent time looking at 32.Qh3 and an eventual mate at h8, but Black's Queen would cause too much heartburn. Finally I realized that 33...Kg7 (Forced) blocks Black's defense against the h8 mate. So yeah, more difficult than most Monday outings.

Oct-05-20  saturn2: 32 Nf6+ gives way for the queen to enter the h file

Oct-05-20  ismet: why there is still NO chessgames.com apps in appstore or android ?
Oct-05-20  saturn2: <stacase >

After 32. Qh3 there is also Qxd4+ 33. Kh1 Qh4 

Oct-05-20  Brenin: <stacase>, <saturn2>: 32 Qh3 Qxd4+ 33 Kh1 Qh4 is answered with 34 Qc3, threatening Qh8#, e.g. 34 ... Rxc3 35 R1f7+ Kh6 36 Rh8#.
Oct-05-20  Predrag3141: Black sometimes foregoes ... f6 and lets White control the kingside. But if he intends ... f6, it gets worse the longer he waits.

7 ... Qb6 may already be too lackadaisical in this regard. Black lost 5/6 in the database with 8 ... cxd4 9 cxd4 f6 10 Nf4 fxe5 11 dxe5 Bb4+ 12 Kf1.

Most common, by about 4 to 1 in the database, is to prioritize ... f6 with 7 ... cxd4 8 cxd4 f6 9 exf6 Nxf6, denying White any early chance to exploit open lines on the kingside or a weak e6 square.

Oct-05-20  TheaN: <32.Nf6+> and mate soon <32....B/Qxf6 (Kh6 33.Qh3+ Kg7 34.Ne8#; Kg7 33.Ne8+ with 34.Qh3#) 33.Qh3+ Kg7 34.Qh8#>. A somewhat unique clearance.
Oct-05-20  Predrag3141: <ismet: why chessgames.com so slow for a long time?>

My recent experience is that often, the moves simply don't load (perhaps they time out so in that sense it's slow).

This happens in the supposedly wonderful Chrome as well as in Edge. So don't blame the browser.

  gawain: I propose a new word "hallusolution." A hallusolution is a solution that is based on a hallucination.

A good example of a hallusolution is 32 R1f7+ Kh6 33 Rh8# which is based on the hallucination that the Black rook sitting on c7 is a pawn.

  pittpanther: I could not get the game to load but it would load other games......I have noticed for the last couple of months that the service is getting poorer and poorer for this site. That is too bad because the daily problem is something I enjoy every day and have for many years!
Oct-05-20  vonKrolock: Nf6+ mates, or win the Queen (15 seconds)
Oct-05-20  vonKrolock: Quick second thought: It's a mate also after Nf6+ Kg7 Ne8+ and Qh3#
Oct-05-20  Damenlaeuferbauer: After long thinking, the Ulf man finally found the mate in 3 moves with the nice knight sacrifice 32.Nf6+!,Kh6 (32.-,Qxf6 33.Qh3+,Kg7 34.Qh8#; 32.-,Bxf6 33.Qh3+,Kg7 34.Qh8#; 32.-,Kg7 33.Ne8+,Kh6/Kh7 34.Qh3#) 33.Qh3+,Kg7 34.Qh8#. He was and is not only positionally, but also tactically incredible strong.
Oct-05-20  woodenplayer: I have found that when the game won't load, clicking a link, such as the name of the White player, and then returning to the page loads the game. Some scripting problem presumably.
Oct-05-20  woodenplayer: I suspect the newish pop-up advertisements are interfering with the game load.

Premium Chessgames Member agb2002: White has a knight and a pawn for a bishop.

The knight blocks the h-file. Hence, 32.Nf6+:

A) 32... B(Q)xf6 33.Qh3+ Kg7 34.Qh8#.

B) 32... Kg7 33.Ne8+ Kh6(7) 34.Qh3#.

C) 32... Kh6 33.Qh3+ Kg7 34.Ne8# (or Qh8#).>

Nice analysis.
A bit more complicated than the average Monday puzzle.

I didn't see the
33.Ne8+ move.

  keypusher: Nice that 32.Nf6+ Kg7 33.Ne8+ is a royal fork, but White doesn't even have to take the queen, since K moves Qh3 mates.

  eternaloptimist: <Brenin> Indeed this puzzle is harder than most Monday puzzles! I didn’t envision a # by ♕h8 until I saw 32. ♘f6+. At first I kept thinking that moving 1 of the ♖s was the correct 1st move in this puzzle. After several minutes of thought I solved it after I saw that if black doesn’t capture white’s ♘ then 33.♘e8+. This is really more like a more difficult than normal Tuesday puzzle or an easier than normal Wednesday puzzle IMHO. I think it should’ve been a Tuesday puzzle
Oct-05-20  messachess: The black K blocks the B from h8! Neat.
Oct-05-20  LeifTerry: <gawain> Ha! I had exactly the same "solution".
Oct-05-20  Nullifidian: 32. ♘f6+

If 32... ♗xf6 (or even ♕xf6) then 33. ♕h3+ ♔g7 34. ♕h8#

If 32... ♔g7 then 33. ♘e8+ is a family fork.

Just kidding.

After 33. ♘e8+ the king has to go back to the h-file where 34. ♕h3# is mate.

Oct-05-20  catlover: <LeifTerry: <gawain> Ha! I had exactly the same "solution".>

That makes three of us. What a terrible way to start the week!

Oct-15-23  Saniyat24: don't often see so many pieces on the h-file...!
