Jul-26-11  benjaminpugh: Black actually has two legal moves after Qe1+. Either Rxe1 or Rf2. Of course, Rf2 just leads to Qxf2#, but at least Black doesn't get mated by a pawn.
Jul-26-11  BOSTER: The double isolator pawns, as usual, are weak and need a good protection, but sometimes, like in this game they show irresistible power.

May nice words have been said about pawn g2, but nobody mentioned anything about g4. And I'd say this is unfair ,because only with help g4 black king was involved in mating net,and I'd say on the position pawn on g4 is hanging the outcome of the game.

And if somebody decided to give the prize only to g2 pawn, g4 would say "Shame of you, guys!" and even could leave the board.

Jul-26-11  drnooo: one small step by stalberg but one giant leap for chesskind
Jul-26-11  garrido.benjamin: very easy
queenne1 check
Jul-26-11  garrido.benjamin: 21.-RxF6 is the began of one beutifull

Jul-26-11  Ghuzultyy: I'm sure I saw it somewhere before.
Jul-26-11  ajile: lol

Took me way too long. Finally realized that it was CHECK on Qe1.

Sep-25-21  Brenin: 21 Rxf6 is an obvious start, but I'm not convinced that there is a forced win for White. Black must recapture with 21 ... gxf6, and then the obvious 22 Ne4 is answered with Rxe4 23 Qxe4 Re8, and Black is safe. Better for White is 22 Rf1 Re5 23 Nf5 Rxf5 24 Qg4+ Kh8 25 Rxf5 Be5, and again it looks although Black can survive. A puzzling puzzle.

  profK: The potential for the 49.g3 mate is just soooo cute!!!

  OhioChessFan: I would guess Black misplayed this but still a spectacular ending.
Premium Chessgames Member
  raymondhow: I got the first two moves, but then the Royal Fork threat 23.Ne4 tempted me, which doesn't work.
Sep-25-21  Dionysius1: It's a long way from 21.Rxf6 to 48.Qe1+ 1-0.

Is cg suggesting White missed something quicker? Or is it just conflating two interesting points in the game?

I must say the final mate is fun!

Sep-25-21  drollere: i had 21. Rxf6 gxf6, 22. Ne4 Qd8, 23. Nxd6 Qxd6, 24. Qg4+ Kh7, 25. Nf5 Rg8, 26. Qxg8+ Rxg8, 27. Nxd6
Sep-25-21  agb2002: White has a knight for a bishop.

White can weaken the black castle with 21.Rxf7 gxf6 22.Rf1, threatening Nf5 and Qg4+:

A) 22... Re5 23.Qf4

A.1) 23... Rxd5 24.Nxd5 Bxf4 25.Nxf6+ Kh7 (25... Kg7 allows an eventual Nf5+) 26.Nxd7 Be3+ 27.Kh1 wins decisive material.

A.2) 23... Rg5 24.Qxf6 Kh7 25.Ne4 Be7 26.Nxg5+ hxg5 27.Qf5+ Qxf5 28.Nxf5 wins a pawn with a much better ending.

A.3) 23... h5 24.Ne4

A.3.a) 24... Rxd5 25.Nxf6+ Kg7 (25... Kh6 26.Qh6#) 26.Qf3 wins.

A.3.b) 24... Rxe4 25.Qxb4 and White has recovered the material while Black's position has worsened considerably.

B) 22... Kh7 23.Nf5 Rg8 24.Qf4 Rg6 25.Ne4 Rxe4 (25... Be5 26.Ng5+ looks winning) 26.Qxe4 as in A.3.b.

C) 22... Be5 23.Nf5 is winning.

D) 22... f5 23.Nxf5 f6 24.Qh4, followed by Ne4, looks very good for White.

Sep-25-21  agb2002: For some reason, I missed 23... Re1 in my line A and Black seems to hold.
Premium Chessgames Member
  Teyss: I got the first 27 moves in 0.05 second but didn't find 48.Qe1+! Which BTW was a Tuesday puzzle in 2011.

Black did not play the best defence, the decisive mistake apparently being 36...Ke7 instead of Kg7. 37.Rc1 threatens Rc7+ and Rc6 pinning the BQ, this explains 37...Qxd5 but then Q+R initiate a K chase.

For info after 21.Rxf6 SF (15 min) gives -0.9.

Sep-25-21  GlennOliver: Endgame brilliantly fought by both players, and a fitting denouement to the struggle.

Sep-25-21  AlicesKnight: The opening part was moderately clear but not conclusive, though tricky for Black, and without silicon less easy to be specific. The final touch was delightful.
Sep-26-21  suenteus po 147: This is an occasion where, because it was a puzzle where I had to guess the next move, I knew the answer was 21.Rxf6, but I didn't know why nor how to follow it up effectively. Funny how chess puzzles can work that way. I've developed a sense of what is a correct move in a puzzle position, but the intricacies of the greater game continue to elude me.
Sep-26-21  TheBish: <agb2002: ... C) 22...Be5 23.Nf5 is winning. ...>

That's what I thought, until the engine showed me 23...Bd4+. Now what? After 24. Kh1 Re5 25. Nxd4 Qg4, Black is ahead (-3.5), so forced is 24. Nxd4 cxd4 25. Qxd4, but engine shows -0.6 for Black (slight advantage) after 25...Qe7 26. Rxf6 (other moves are worse) 26...Qe1+ 27. Rf1 Qe3+ 28. Qxe3 Rxe3. I'm thinking White should be able to draw without much trouble, but can't push for a win.

So not the best puzzle maybe? Many of these POTDs seem to not be clear wins in every line. Much like many of Tal's sacrifices!

Sep-26-21  agb2002: <TheBish: <agb2002: ... C) 22...Be5 23.Nf5 is winning. ...> That's what I thought, until the engine showed me 23...Bd4+. Now what? After 24. Kh1 Re5 25. Nxd4 Qg4, Black is ahead (-3.5)>

And the alternative 25.Qd3, to keep the knight on f5, is also losing according to DroidFish, surely because the queen should be attacking instead of defending.

A bad day at the office.
