Feb-24-06  Mating Net: I didn't get 38.Nh7! To me, it is a super sharp move. It combines two tactical themes. Thedeflection of the Black King, and if the King doesn't capture the beast, an intermezzo via 39.Nxf6+. Pretty cool.
Feb-24-06  JustAFish: I followed Starkidaway's line as well... Rg6 was hard to see, though.
Feb-24-06  pwrstick: Hello again all,

Would someone kindly suggest the final end game sequence? I'm having difficulty seeing why black resigned (other than being down a rook).

  tpstar: <pwrstick> After 44. g4 Black's endgame is very hard to hold, like 44 ... Nd8 45. Rd7 Nb7 (45 ... Nc6?? 46. Rd6+; 45 ... Ne6?? 46. Rd6) 46. Rff7 and the Pg7 falls. But 44 ... Rb2?? was fatal due to 45. Ra6 winning the Ne6 next move.
Feb-24-06  pwrstick: I suppose Ra6 to threaten the knight is rather devastating as it pins it to the king. And there's no way to defend its eventual capture...
Feb-24-06  VinnyRoo2002: To answer Life Master AJ's question, I found an alternative solution with 38. Ne6 Rxc8 39. Rc8 Kh7 40. Nf8+ Kg8 41. Nd7+ winning the exchange also. Not sure if this end position is superior or inferior to the one in the game though.
Feb-24-06  VinnyRoo2002: Sorry, I overlooked 39... Kf7 when white doesn't win any material. I did see the Nh7 line though.
Feb-24-06  c o r e: I soved today's puzzle on intuition alone- then spent five times as long trying to disprove it. I kept thinking to myself 'I must have missed something in this line...'

I find that I all too often underestimate my opponent's counterplay in these situations, but today's puzzle position would have had me nearly throwing the win away if controls were at 40.

Feb-26-06  LIFE Master AJ: My alternate solution involved 37.Rcc7, Rg6; 38.Ne6, which I originally thought won ... and better than the game. (But apprently not.)
Oct-13-21  Brenin: The N fork 38 Nh7 was not immediately obvious (not to me, anyway), but it works because 38 ... Rxc8 39 Nxf6+ is check, so Black must play 39 ... gxf6 and then 40 Rxc8+ wins the exchange. Of course, 38 ... Kxh7 loses to 39 Rxf8. At the end, 45 Ra6 wins the N.

  drollere: this was easy. 38. Nh7 Rxc8, 39. Nxf6+ gxf6, 40. Rxc8+ or 38. Nh7 Kxh7, 39. Rxf8 Rxf8, 40. Rxf8

  An Englishman: Good Evening: That ranks among the funniest winning moves I have ever seen. Actually laughed upon solving this one.
Oct-13-21  TheBish: White to play (38.?) "Medium/Easy"

White wins an exchange with 38. Nh7!, i.e. 38...Kxh7 39. Rxf8 or 38...Rxc8 39. Nxf6+ (zwichenzug!) gxf6 40. Rxc8 with an elementary win. An oldie but a goodie! Not sure if I've seen this particular game position before, or just one from a similar game.

Oct-13-21  stacase: Somewhat similar to yesterday's opus, only this time I got it right.

Yesterday was a real "DOH!" experience.

Oct-13-21  saturn2: 38.Nh7 and black can choose between R+N vs 2R or alternatively N vs R
Oct-13-21  mel gibson: I saw that.

  agb2002: Black threatens hxg5.

The black king protects the rook on f8. Therefore, 38.Nh7:

A) 38... Kxh7 39.Rxf8 wins the exchange.

B) 38... Rxc8 39.Nxf6+ gxf6 40.Rxc8+ wins the exchange.

C) 38... Rxf2 39.Nxf8 wins a rook for a pawn.

D) 38... Nxf2 39.Nxf6+ and Black will lose all the pieces.

  raymondhow: After winning the exchange, the 40th move appears a matter of positional taste. I went with 40.g3.

  FSR: 38.Nh7! is hilarious.
Oct-13-21  goldfarbdj: My choice was 38. Ne7+, which has the disadvantage of not actually being a legal move.

  Once: Ha ha!

This is another of those moves to file under "surely that can't work, can it?"

I'm with FSR and an Englishman. Astonishing move.

  TheaN: <38.Nh7 +-> was actually pretty apparent to me, I just spend a bit too long checking possible answers. Tl;dr, Black's always a tempo short given Nxf6 or Rxf8.

Black chooses the 'most material' endgame, but it's rather trivial because the White rooks are simply much better.

Oct-13-21  AlicesKnight: I found Nh7, and the win of the exchange comes in various options. A 'matter of technique' after that, meaning it takes a while.
