  agb2002: <Dlegvold> 44.Be8+:

A) 44... Kxe8 45.g6 Bxg3 46.gxh7 (46.Kxg3 Rh1) wins.

B) 44... Kf8 45.g6 wins.

C) 44... Kg8 45.g6 hxg6 (45... Bxg3 46.Bf7+ Kf8 47.gxh7 wins) 46.Bxg6 Bxg3 47.h7+ Kf8 48.h8=Q(R)#.

Feb-12-19  ChessHigherCat: <SpamIAm: Figment of my i-magyar-nation! ;) lol!

Dlegvold: Nice one. 44. Be8+ and if Kxe8 45. g6 wins easily, but what about 44..Kf8 or Kg8? You should propose it as a GOTD

Feb-12-19  landshark: I made it unnecessarily complicated but I think this still wins:

42. Nf7 Rh7 43. e7 Rxh6 44. Nxh6+ Kg7 45. e8=Q.

White's activity makes it impossible for Black to exploit the marooned N on h6.

42 .... Rxf7 43. exf7+ Kxf7 44. Rc7+ Ke8 45. Rxb7 is equally disastrous for Black.

Obviously, 42.Qxg7+is simply better -

Feb-12-19  Dlegvold: Correct agb2002 and ChessHigherCat. The final moves were: 44. Be8+! Kg8 45. g6 Bxg3 46. Bf7+ Kf8 47. hg 1-0
Feb-12-19  landshark: <Diegvold> <agb2002> Another branch is 44... Kxe8 45.g6 Kd7 46.gxh7 Ra8 47. h8(Q) Rxh8 48.Bxh8 Bd8 49. Bg7 and the other h-pawn cannot be stopped
Feb-12-19  Dlegvold: Pawn promotion puzzles are cool because they involve complete disregard for material in return for promoting a pawn, often followed by rapid mate.
Feb-12-19  King Harvest: <SpamIAm: Solution is a Podzielny of Cako.>

Made me groan, and then

<SpamIAm: Figment of my i-magyar-nation!>

made me Groningen.

Feb-12-19  Dlegvold: Whoops! I mean 47. gh 1-0
Feb-12-19  Dlegvold: Yes land shark! I remember seeing that variation during the game an being pleased I had doubled h pawns!😉
Feb-12-19  Cheapo by the Dozen: Meet the new queen, just like the old one.
Feb-12-19  saturn2: I saw 42. Qxg7+ Kxg7 43. e7

43...Re4 44. exf8=Q+ Kxf8 45. Nxe4

43...Nd7 44. Rc7 Nf6 45. e8=Q+

Feb-12-19  Dlegvold: <landshark> the “best” line is 44. Be8+ Kxe8 45. g6 Ra8 46. gh Kf7 47. g8=Q Rxh8 49.Bxh8 Bd7 50. Bg7 and white is a piece up and completely winning.
Feb-12-19  SpamIAm: <King Harvest> Don't Groningen too much... push that passed e-pun!
Feb-12-19  mel gibson: Not that easy.
Stockfish 10 says mate in 16.

Feb-12-19  zb2cr: 42. Qxg7+, Kxg7. The White Queen has given up her life, but ...

43. e7 and a new White Queen will come to life.

Feb-12-19  TheaN: 12 February 2019

<42.?>

Reincarnation at play, and that at <move 42>. Almost as if it was meant to be.

<42.Qxg7+ Kxg7 43.e7 +-> is the easiest path to winning a rook and the game, because the Queen reappears on e8 :>

Feb-12-19  DrGridlock: <landshark>

42 Nf7 is also winning, but not in the line you give. After 43 e7, black has checks with his bishop and rook that complicate things for white. Better is 43 Qe3 which leads to a +3 computer eval for white.

The line I followed in the Nf7 line is Rxf7, which is quite bad for black.

Feb-12-19  lost in space: 42. Qxg7+ Kxg7 43. e7 and the pawn is queening

  whiteshark: Potz-Blitz strikes again!
Feb-12-19  Damenlaeuferbauer: Of course my old friend IM Karl-Heinz Podzielny jun., also known as "Potz-Blitz", played the ingenious queen sacrifice 42. Qxg7+!,Kxg7 43. e7! +-. Despite being a child of bottle like the immortal Latvian WC Mikhael Tal, he is an incredible quick chess player and won the German blitz chess championship 7 times and the German rapid chess championship 3 times. Furthermore he is a tremendous mail chess player. He played an really impressive strategical over-the-board Czech Benoni game with the black pieces against W. Schmidt, Trnava 1984.

  gawain: That is a very nice puzzle! I had to give it three different thinks.
Feb-13-19  patzer2: The dual threat of a Knight Fork and a Pawn promotion with 42. Qxg7+ Kxg7 43. e7 +- easily solves this week's Tuesday (42. ?)puzzle.
Feb-13-19  patzer2: The game had several twists and turns where both players missed stronger moves. Black's late game mistake which proves decisive appears to be 22...Nh5?, allowing 23. Bg4 +- (+2.29 @ 28 ply, Stockfish 10).

Instead, 22...Nh7 = (0.00 @ 30 ply, Stockfish 10) looks to hold the position level.
