  doubledrooks: The black queen is the only piece stopping Rh8+ and R1h7#, so a deflection move seems like a possibility. Therefore, 36. Qd6 and now:

a. 36...Qxd6 37. Rh8+ Kg7 38. R1h7#

b. 36...Qc3 37. Qf6

b.1 37...Qxf6 38. gxf6 and 39. Rh8#

b.2 37...Qc2+ 38. Ka1 and mate on h8 is unavoidable.

c. 36...Qxg5 37. Rh8+ and 38. R1h7#

Apr-05-11  stst: Easy...but with a trap.
Crux is twofold, to launch an uninterrupted attack via Rh8 and also not to let the Bk K flee via f8. Try:
36. Qd6 (to divert the Bk Q, as well as guarding f8 and f6) Now Bk Q has no good place to go
36.....QxQ? or Qxg5P or any where will leave the diagonal that W exactly wishes. Then 37.Rh8+ (now without being captured by the Bk Q, leaving the Bk K the only square to go...Kg7 38. Rh7# thanks to the P at g5

If 36... Qxg5, the same:
37.Rh8+ Kg7
38.Kg7 Rh7, Bk K still has no flee square (f6 guarded by WQ, h6 of course is the WR-file.)

Trap will be 36.Qh3, or the direct failure 36.R8+.

Apr-05-11  sevenseaman: << fyjx: sevenseaman i think the key is Bg8, then zugzwang>

Bg8, Ra7 refutes.

Apr-05-11  CHESSTTCAMPS: <David2009:> I found and tried your link to EGT (page 2) before I read your entire post. From your final diagram in the post (arising from the 36.Qh3 line), white has a more forcing win with 40.Qb7+ Kd6 41.Qd5+.

A related line, 36.Qh3 f5 36.Rh8+ Kf7 37.Qh7+ Qg7 38.Qxg7+ Kxg7 39.R1h7# ends up looking like this:

1.Qh4+ Kxe3 2. Bxg5+ Qf4

Sorry but endzone intereference with licence to cook:

15 rf2 does nt count.

Pleasant Botvinnik style Kf1?

  YouRang: Not too hard once you notice that white's threat of Rh8+/R1h7# is only being stopped by the black queen's defence of h8, and noticing that shouldn't take long.

The objective then is to deflect the queen effectively. White has two reasonable deflection attempts: 36...Qd6 and 36...Qd5. Are either (or both) of them effective?

In either case, the black queen's only flight square where she still guards h8 is at c3. So the question is, "where do we want our queen to be after <36...Qc3>?

If our queen were on d5, we don't have much to do. However, if our queen were on d6, then we can block and attack the black queen with <37.Qf6!>. Black can get in one check with <37...Qc2+ 38.Ka1>, but then it becomes clear that black can only delay mate with some spite checks.

Apr-05-11  HowDoesTheHorsieMove: I chose Qh3, since I could see it would win a rook.

I had considered Qxc5, but while that wins it was far too deep for me. Well, even the correct solution of Qd6 was too deep for me.

  morfishine: <eblunt> I realized thats the point of the puzzle: 36.Qd6 wins on the spot. 36.Qh3 maneuvers a few more turns, all ending up the same: White wins
Apr-05-11  dadoktor: I believe Qh3 which i found is also winning but i guess not so effectively
Apr-05-11  LIFE Master AJ: <chrisowen> I am not smart enough to even figure out what you said.

Translation?

  morfishine: <LIFE Master AJ> & <TheFocus> Basically, what <chrisowen> said was: Inner-tube above grass while screwdriver leaves soft-palate to avoid the drizzle; oh-well, its over-under so they squirm and say no-way but the clothesline gives us a white-flag before dawn. Got it? Its easy once you get the hang of it.
Apr-05-11  MountainMatt: I too came up with a quick 36. Qh3, with a not too painful winning sequence to follow. But Qd6 is quite beautiful...which is why I didn't see it.

Good to see you back for more torture, <ChessPieceFace>. Keep up the good work - we'll reach the promised land one day!

  TheFocus: Oh. Well, that makes sense.
Apr-05-11  picard: <AJ> I agree, you are not smart
Apr-05-11  drnooo: the botvinik quote brings up an int question: how many great masters, like he have not played blitz he may be the Lone Ranger there
Apr-05-11  drnooo: does anyone here know of any great gm, by great I mean the likes of botvinik who also shunned blitz?
Apr-05-11  drnooo: with ole chris this at least we must admit: he makes Finnegans Wake a piece of cake
and that is very hard to do
he turns inside out LaMOTTS
too saccharine to YIKES his own lemon sour
BOTH like ole Jimmy Joyce himself, impossible to swallow.

  Domdaniel: The key to 'difficult' writers is their voices. I couldn't understand William Burroughs until I heard him do a reading -- everything clicked, the Martian-mandarin junky from St Louis carny schtick fell inna place.

Same with Joyce. You just need to hear it in Dublinese.

For *chrisowenish*, a certain English accent - educated, but not a toff - is helpful, innit.

I love the crisp humor you put in your post. (May be only the first from you I've read.)

Apr-06-11  fyjx: sevenseaman: << fyjx: sevenseaman i think the key is Bg8, then zugzwang> Bg8, Ra7 refutes.

got it. Ba2. just needed to block that A rook.

Apr-06-11  fyjx: gilmoy had it. just got around to reading it. i had the right piece just missed the Ra7 move.

Yes, you had the right piece, the right idea but missed it by a whisker.

When I saw your Bg8 I knew you will not be stopped from cottoning on to Ba2. Well done.

<Gilmoy> had it at c), but one has to read it carefully in order to be able to grasp. Well done again as you are the only one to decipher it.

I think now you'll appreciate the torture I underwent. To start with Ba2 looks a very weird idea, even if it is logical.
