  Dionysius1: Hi <trnbg>. That raises an interesting question: if there is more than 1 solution, do we get extra points for finding the one most likely to relate to the level of difficulty specified? Regardless if it's the easiest/most difficult?
Nov-14-18  saturn2: < trnbg 29.Rf1 (what else?)>

29 Rc3

Nov-14-18  malt: Have 26...Re2+ 27.N:e2
(27.Kh3 Qf3 and 28...Qg4# )

27...Q:e2+ 28.Kg3 Qf3+ 29.Kh4 Qg4#

Nov-14-18  patzer2: White loses his advantage after 13. g4?! Nbd7 = (0.00 @ 30 ply, Stockfish 9).

Instead, completing development with 13. Bg5 Nbd7 14. Ne2 Qd8 15. 0-0 ⩲ (+0.57 @ 32 ply, Stockfish 9) gives White the better chances.

Nov-14-18  TheaN: Wednesday 14 November 2018

<26....?>

How typical. I saw <26....Re2+> with pandemonium, correctly seeing A and B:

A) <27.Kg1 Qe3#>

B) <27.Kh3 Qf3! with Qg4#>

C) <27.Nxe2> however, here I lost the thread thinking I could play Qf3+ and Qf1#. The Rook's covering f1 so that doesn't work. Obviously Qxe2+ is best, but I still think Black can salvage <27....Qf3+?! 28.Kg1 Qxe2> now, yeah >_> <29.Rf1 (Rc3 Bd1! 30.h4 (Qxd1 just prolongs) Qf1+ 31.Kh2 Qf2+ 32.Kh3 Bg4#) Qg4+ 30.Kf2 Qxf4+> removes defense of e5, and the key is now that Black follows up with Re8+ straight away, or repeats a Queen check and then plays Re8 and the White position is in shambles. Quite a few variations though, so just 27....Qxe2+ will do.

Nov-14-18  patzer2: The losing move appears to be 14. f4?, allowing 14...Re8+ -+ (-1.83 @ 27 ply, Stockfish 9).

Instead, 14. g5 Nh5 15. Ne2 Ne5 16. Ng3 g6 17. Be2 Qa5 18. Bd2 Re8 19. 0-0 = (-0.05 @ 32 ply) holds it level.

Nov-14-18  TheaN: <PawnSac: NO! after 27.Kh3 NOT ..Qf3 but the immediate ..Qg4# !!>

Intestering concept here (you do make it a bit more dramatic than necessary: unless Black has one second on the clock #2 or #1 don't exactly lose games, also, it's confusing now because you mean 28.Kh3 in the Nxe2 variation, 27.Kh3 <does> lead to 27....Qf3): why do so many players play 26....Re2+ 27.Nxe2 Qxe2 28.Kh3 Qf3+?!

Pretty sure this is a tunnel vision concept: in variations with the Knight on g3 only Qf3 wins, as Black has no control over g4 from d3. After taking on e2, our mind gets stuck in that thinking process, therefore playing 28....Qf3+?! 29.Kh4 Qg4# instead of 28....Qg4#.

Nov-14-18  SEVEN: White's Queen on A1 ?. This is not something you see every day.
Nov-14-18  Crowaholic: "NO! after 27.Kh3 NOT ..Qf3 but the immediate ..Qg4# !!"

This is an illegal move. You are apparently confusing

26. ..Re2+ 27. Kh3 Qf3 28. (any) Qg4#

with

26. ..Re2+ 27. Nxe2 Qxe2+ 28. Kh3 Qg4#

Nov-14-18  stacase: <Crowaholic: "NO! after 27.Kh3 NOT ..Qf3 but the immediate ..Qg4# !!" <This is an illegal move ...>>

Thanks (-: I waited to see if others noticed that something was wrong. I'm pretty much a wood pushing patzer and even worse at reading Chess notation - so instead of stepping in it....

Well thanks for confirming that I'm not nuts (-:

White had the option of not accepting the Rook sacrifice. But Black had found a way to give his opponent two choices - both bad!

Sometime ago chessgames dot com added those little hints when you post - and I think one of them says something about giving your opponent only bad choices.

Nov-14-18  ChessHigherCat: <stacase: Well thanks for confirming that I'm not nuts (-:>

Had me scared, too!

Nov-14-18  trnbg: <saturn2: < trnbg 29.Rf1 (what else?)> 29 Rc3>> On 29 Rc3 (after 26...Qf3+ 27.Kg1 Re2 28.Nxe2 Qe2), Black wins nicely with 29...Bd1!, cutting off the white queen from the defense.
Nov-14-18  Walter Glattke: Akso wins second best 26.-Qf3+ 27.Kf1 Re2 28.Nxe2 Qxe2 29.Rf1 Qg4+ 30.Kf2 Qxf4+ 31.Kg2 Qg4+ 32.Kf2 Ne4+ 33.Ke1 Re8 with mating e.g. 34.Rhg1 Ng3+ 35.Kd2 Qe2+ 36.Kc3 Re3#
Nov-14-18  ChessHigherCat: <trnbg: <saturn2: < trnbg 29.Rf1 (what else?)> 29 Rc3>> On 29 Rc3 (after 26...Qf3+ 27.Kg1 Re2 28.Nxe2 Qe2), Black wins nicely with 29...Bd1!, cutting off the white queen from the defense.>

This is more of a "So I'm not crazy" than "I told you so" question, but that's exactly what I said in my first post in this thread, but then I thought it must be wrong because <sudplatov> found a faster mate. It was really okay, right?

<CHC: Not sure about this but what about: 26...Re2+ 27. Nxe2 (Kh3 Qf3 threatening Qg4#) Qf3+ 28. Kg1 Qxe2 29. Rc3 Bd1 threatening Qf1#?

  gawain: Two Black pieces camped in the middle of White's position--and then they are joined by a third! White is helpless.
Nov-14-18  saturn2: <trnbg On 29 Rc3 (after 26...Qf3+ 27.Kg1 Re2 28.Nxe2 Qe2), Black wins nicely with 29...Bd1!>

Can you please show how? What hapoens after for example 29.. h3 Qf1+ 31. Kh2 Qxf4+ 32. Rg3

Nov-14-18  Cheapo by the Dozen: I was also of the ... Qf3+ persuasion.

  Bubo bubo: Black forces mate with 26...Re2+:

A) 27.Nxe2 Qxe2+ 28.Kg/h3 Qf3+ 29.Kh4 Qg4# or 28.Kg1 Nf3#

B) 27.Kh3 Qf3, and White cannot prevent 28...Qg4#.

After taking on e2, our mind gets stuck in that thinking process, therefore playing 28....Qf3+?! 29.Kh4 Qg4# instead of 28....Qg4#. >

It's also possible in the tree of analysis, if one looks at Qe2+ Kg3 first, then Qf3 and Qg4 follows, SO, when considering Qe2+ Kh3 it is very easy for the brain to think.. OH! it's mate by the same sequence, and miss the fact that Qg4 immediately is shorter.

I have done the same thing with other GOTD positions, where after 10 seconds of consideration i see a forced MATE IN 4, and i stop analyzing. why? because it's mate! and then realize after looking at the actual game there was a mate in 3 by a different method. But how many of us, once we see a forced mate, start looking for a shorter mate?! No. when the clock is ticking... POUNCE ON IT!

Nov-14-18  DarthStapler: Doesn't Qf3+ also work?
Nov-15-18  saturn2: <ajile>Thx for the analysis. Originally I went for h4 then I saw that black can check on g4.That is why I took h3 overlooking the mate in one.
Jan-25-19  Skewbrow: PawnSac: In the variant where I suggested the manouver Q->f3->g4 mate, the queen starts from d3. How do I move her to g4 in one move??
