  agb2002: The material is identical.

The rook on b8 is defenseless. Therefore, 27.Nf6+ (27.Qg3 Qxd4+):

A) 27... gxf6 28.Qg3+ Kh7 29.Qxb8 Qxd4+ 30.Kh1

A.1) 30... Nd7 31.Qd8 + - [R vs n+p] and the double threat Rd1 and Re8.

A.2) 30... Kg7 31.Qg3+

A.2.a) 31... Kh7 32.Re8 Qc5 33.Ne4 wins due to the threats Nxf6+ and Nxc5.

A.2.b) 31... Kh8 32.Re8 Qc5 33.Ne4 Qb4 34.a3 wins.

A.3) 30... Qc5 31.Ne4 Qb4 32.Nxf6+ Kg7 (32... Kh8 33.Qg3 wins) 33.Nh5+ followed by 34.Qg3 wins.

B) 27... Kf8 28.Nxd7 + - [Q vs n].

  ChessHigherCat: The only tricky thing is to avoid the red herring 27. Qg3 attacking the rook on b8 and preparing the royal fork, because unfortunately black can play Qd4+ covering the vital square f6.
Mar-14-17  leRevenant: Safar so good, up to move 45.
Mar-14-17  morfishine: <27.Nf6+> followed by <28.Qg3+> snags the rook winning the exchange; Black scrambled around admirably though all for naught

*****

Mar-14-17  saturn2: <agb2002 A.1) 30... Nd7 31.Qd8 + - [R vs n+p] and the double threat Rd1 and Re8.> Black has 31..Nxb2 preventing the fork Rd1 and also the white rook cannot leave the 1st rank.
Mar-14-17  Carlos0012358: After 31.Qf2, brilliant white N play to set up the crushing 40.Rxf6.
Mar-14-17  Tiggler: The knight fork wins the exchange, but the rest need not have been so quick if black had played 29...Qxd4+
Mar-14-17  groog: The first few moves weren't too difficult, then it gets a little harder.
Mar-14-17  sid299792: A tad little indecisive for a Tuesday ,don't you think?
Mar-14-17  schachfuchs: These two white knights were really poisonous! After the exchange winning fork 27.Nf6 the remaining knight flies around like a deadly mosquito: 32.Ne4-c5-xb7-d6-e4xf6. Nice game!

  swclark25: Agree with <saturn2> and <YouRang> that 29..Qxd4+ and following is better for Black.

But, looking at the game line, why do you think that Black didn't take Knight with 34...Qxb7 ?

Mar-14-17  RandomVisitor: <swclark25>I missed that myself. But from the diagram below Ne8 would then be hanging.

Because it leaves Ne8 undefended, allowing <36.Rxe8>.

Worse, black's other knight (Nf8) has nowhere to go (36...Nd7? 37.Qg3 soon mates). So black has to guard it with the queen via <36...Qb4>

Black is practically paralyzed in this very awkward and uncomfortable position.

Mar-14-17  BOSTER: 34...Qxb7 Rxe8
This is not a good idea to exchange when you behind in material.
Mar-14-17  RandomVisitor: 19...Bg4 might have equalized: the d-pawn is now hanging and f3 does not work

  swclark25: Thanks all...I overlooked the White Rook on the e-file bearing down on the Dark Knight (whoops!). Sometimes I see something, but mostly I miss something...

Mar-14-17  BOSTER: Many years ago <CG> would never count such pos as < puzzle >.
Mar-14-17  stst: See only one meaningful move:

27.Nf6+ gxN (else Kh8, 28.NxQ)
28.Qg3+ Kh7/h6 (Ng6 not effective: 28.QxN+)
29.QxR threatening Re8 ... prevailing in both material and control.

Mar-14-17  stst: <Many years ago <CG> would never count such pos as < puzzle >.>

A little defense for CG:
1. CG is not a composer, so hardly any really NEW stuff. 2. Not many real games are really interesting - those offering sparkling combinations are especially rare - those that are "good" (hard to define) Puzzles are even rarer - and those comprising really good puzzles will be just a handful. 3. The reservoir is quite limited, so endless drawing will soon dry it out. 4. Almost only way to present "fair" to "good" puzzles is to recycle them!!

Hence we see occasionally repeated puzzles.

Do you feel better - CG / Kibitzer ?!?

  YouRang: <stst><28.Qg3+ Kh7/h6 (Ng6 not effective: 28.QxN+) >

I think you meant 28...Ng6 not effective: <29.QxR+>

Mar-14-17  BOSTER: <stst>.
Thanks for opinion, but "There's no accounting for taste".
Mar-14-17  Ariogermano: Fantastic comment youRang !

  agb2002: <saturn2: <agb2002 A.1) 30... Nd7 31.Qd8 + - [R vs n+p] and the double threat Rd1 and Re8.> Black has 31..Nxb2 preventing the fork Rd1 and also the white rook cannot leave the 1st rank.>

31... Nxb2 loses to 32.Re8 and mate soon (the white knight covers d1) but 31... Qf2 followed by Nce5 seems to build a fortress.

Instead of 31.Qd8 either 31.Qxb7 or 31.Qb3 are much stronger according to Stockfish.
