  Penguincw: Thursday puzzle, entering today 3/3.
Damn, nearly got it! I got 24.Rxh7+ Kxh7 25.Rh1+. At this point, I went for 25...Kg8 26.Ne7++ 10 (double check and mate). 26.Nf6++ 10 works as well. However, black here played 25...Kg6. While I didn't consider that in my calculation, I'm not sure if I would've seen the rest of the moves OTB. 

Mar1016   diagonalley: 24.RxN+ is an absolute must! ... easy for a thursday :) 

Mar1016   dfcx: white is already up an exchange with B+P for a rook. But the material count does not matter as much here, as white hunts down the king. 24.Rxh7+ Kxh7 (Kg8?? 25.Nxf6#) 25.Rh1+ Kg6 26.f5+ (not Q+ as black plays f5) Kxf5 27.Ne3+ Kg6 28.Qxg6 Kf7 29.e6+ Kg8 30.Bh6 Rf7 31.Qg6 and mates in two. 

Mar1016   stacase: <diagonalley: 24.RxN+ is an absolute must! ... easy for a thursday :)> Pretty much my thoughts, but like Penguincw I don't know that I could have concluded the merry chase that ensued with a win. Great positions can sometimes evaporate. 

Mar1016   FlashinthePan: After 30.Bh6, Black has only 30...Rf7 and now the zwischenzug of 31.Qg6! before 31.exf7 (allowing 31...Kxf7 then 32.Qxg7 Ke6 and avoids immediate mate) is crushing. 

Mar1016   Lowie: <Shadout Mapes: Here's a nice game with a humorous ending.> Funny too, that after 20...Bf6 the bishop stays en prise for 10 moves. And when he finally does move, it is to end the game.

Mar1016   WorstPlayerEver: I can't take this game any seriously.
White plays Bc4Bb3Bc4 to finally get uh Black rook on c4 (RxB). That's just too ridiculous! 

Mar1016   morfishine: <24.Rxh7+> Yada, Yada, Yada... 

Mar1016
  Dionysius1: Ah now that is a heartlift! Talk about a mating net. I particularly like 27. Ne3+ when black can't make either of the legal captures, and 28.Qxg4. Not even a check but the threat of Qh5 is lovely/horrible. 

Mar1016   CHESSTTCAMPS: Not only does white have the material advantage of an exchange for a pawn, but the black king is very exposed. With both the bishop and Rh5 en prise, white can commit to the forcing exchange sacrifice without thinking twice. 24.Rxh7+! initiates a king hunt, pretty much forced anyway.
24... Kxh7 (Kg8 25.Nxf6#) 25.Rh1+ Kg6 (Bh6 26.Bxh6 is winning) 26.f5+! and now: A.26... Kxg5 27.Qf4#
B.26... Kxf5 27.Ne3+ Kg6 28.Qxg4! Kf7 (fxg5 29.Qh5#) 29.e6+ Kg8 30.Bh6 wins B.1 27... Kxg5 28.Qxg4#
B.2 27... Kxe5 28.Qf4#
C.26... Kf7 27.Nxf6+ d5 (e6 28.Qxe6#) 28.Nxd5 and the panoply of threats (Nxe7+, Bxe7, Qxg4) is overwhelming. 

Mar1016
  agb2002: White has a rook for a bishop and a pawn.
Black threatens 24... Bxh5 and 24... fxg5.
White can expose the black king with 24.Rxh5+ Kxh7 (24... Kg8 25.Nxf6#) 25.Rh1+: A) 25... Kg6 26.f5+
A.1) 26... Kxg5 27.Qf4#.
A.2) 26... Kxf5 27.Ne3+ Kg6 (27... Kxg5 28.Qxg4#; 27... Kxe5 28.Qd5#) 28.Qxg4 A.2.a) 28... fxg5 (or 28... f5) 29.Qh5#.
A.2.b) 28... Rh8 29.Bxf6+ Kf7 30.e6+ Kf(g)8 31.Qxg7#. A.2.c) 28... Kf7 29.e6+ Kg8 30.Bh6 and mate in three. A.2.d) 28... Bh8 29.Bxf6+ Kf7 30.e6#.
A.2.e) 28... Rg8 29.Bxf6+ Kf7 30.e6+ Kf8 31.Bxg7+ Rxg7 32.Rh8+ Rg8 33.Q(R)xg8#. A.3) 26... Kf7 27.e6+ Kg8 28.Bd2 and Black is helpless against Qxg4, Rg1, etc. B) 25... Kg8 26.Nxf6#.
C) 25... Bh5 26.Rxh5+ Kg6 27.Qd3+ f5 (27... Kxh5 28.Qh7+ Bh6 29.Qxh6#; 27... Kf7 28.Bh4 +  [N vs P]) 28.Rh4 +  [N vs P]. D) 25... Bh6 26.Bxh6 just loses a piece.

  patzer2: Today's Thursday puzzle reminded me of the Carole King song "You're so far away" with the lyric "Doesn't help to know you're just time away." Got as far as 24. Rxh7+! Kxh7 25. Rh1+ Kg6 26.f5+ Kxf5 27. Ne3+ Kg6 in my calculation, but did not see enough ahead in this King Hunt to realize that 28. Qxg4! (diagram below) forces mateinfive (Deep Fritz 15 @ 25 depth): click for larger viewHere (diagram above) after 28. Qxg4!:
If 28...fxg4?, then 29. Qh4#.
If 28... Rh8, then 29. Bh6+ Kf7 30. e6+ Kf8 31. Qxg7#. If 28...Kf7, as in the game continuation, then the mateinfive goes 29. e6+ Kg8 30. Bh6 where Black resigns in lieu of 30...Rf7 31. Qg6 Bc6 (31...d5 32. exf7+ Bxf7 33. Qxg7#) 32. Qxf7+ Kh7 33. Qxg7#. In looking for a Black improvement, the computer suggestion 18...Rxc3! looks much better than 18...Rxc4 =. After 18...Rxc3! (diagram below),
click for larger viewDeep Fritz 15 indicates play (diagram above) might go 19. Qxc3 Nxg5 20. hxg5 dxe5 21. fxe5 Qb8 22. Qe3 Qxe5 23. Rhe1 Qxe3+ 24. Rxe3 Re8 25. Ne2 Bc8 (0.83 @ 20 depth) with two pawns for the exchange and an advantage for the second player. 

Mar1016   Eduardo Leon: I haven't consulted with an engine, or even used a physical chessboad to check the following lines, so this analysis might be flawed. The main line is highlighted. <24.♖xh7+ ♔xh7 25.♖h1+ ♔g6 26.f5+! ♔xf5> 26...♔xg5 27.♕f4#, 26...♔f7 27.♘xf6+ d5 28.e6#.
<27.♘e3+ ♔g6>
27...♔xg5 28.♕xg4#, 27...♔xe5 28.♗f4#.
<28.♕xg4! fxg5>
28...♔f7 29.e6+ ♔g8 30.♗h6.
<29.♕e6+ ♖f6>
29...♗f6 30.♕f5+ ♔f7 31.e6+ ♔g7 32.♕h7#.
<30.exf6 exf6>
30...♗xf6 31.♕g8+ ♗g7 32.♖h7.
<31.♕g8 ♕e7 32.♕h7+ ♔f7 33.♘f5 ♕f8 34.♖e1> And there's no way to stop both threats 35.♘xg7 ♕xg7 36.♖e7+ and 36.♕xg7+ ♔xg7 37.♖xe8. 

Mar1016
  kevin86: The king is forced out in the open by a sacrificial rook. 

Mar1016   YetAnotherAmateur: 24. Rxh7+ is the obvious place to start.
24. ... Kxh7
25. Rh1+ Kg6 (Kg8? 26. Nxf6# or Nxe7# due to doublecheck)
26. f5+ Kxf5 (Kf7? 27. Nf4+ e6 28. Qxe6#)
27. Ne3+ Kg6 (Kxe5 28. Qd5#, Kxg5 28. Qxf4#)
Now this is where things get a bit trickier, because white can no longer succeed by simply playing checks. Most of those ideas are met with f5, which stops a lot of the lines of attack on the king. 28. Qxg4 (threatening Qh5#)
A) 28. ... Kf7
29. e6+ Kg8
30. Bh6 and now it's completely hopeless for black.
B) 28. ... Bh6
29. Qh5+ Kg7
30. Bxh6+ Kg8
31. Rg1+ and again there's little for black to do but throw in the towel. 

Mar1016   schachfuchs: The whole game was a very clear, stringent execution by Sherzer! @Eduardo In my calculations, I prefered 29.Qh5+ after a short look at 29.Qe6+ ;) @Patzer Thanks for great move 18...Rxc3! that changes things completely! 

Mar1016
  whiteshark: Got it in the second running. <27.Ne3+!> was the hardest move to find. 

Mar1016   Eduardo Leon: <schachfuchs> D'oh! I knew I was missing something. Thanks. 

Mar1016   scholes: After 27 kg6 i gave up. seemed too long for thursday 

Mar1016   stst: The inviting initiative is RxB+, else White's R is under attack and other moves loses momentum. So try 24.RxB+ KxR (if
(A) ..... Kg8 will get it into a mating net:
25.Nxf6 dbl+ Kg7
26.Rh7 Kg6
27.Qe4#)
(B)28.Rh1+ (Bi) Kg6
26.f5+ Kxf5
27.Ne3+ Kg6 (if ..... KxB, 28.QxP#)
28.Qxg4 Kf7
29.e6+ Kg8
30.Qh4 and no defense to Qh7#
(Bii)
25.......... Bh6
26.RxB+ Kg7
27.f5 fxg5
28.Re6 Rxf5
29.Qxg4 Rf8
30.Qxg5+ Kh8
(else if .... Kf7, 31.Qg6#)
31.Rh6#
see if the game proceeds in other lines... 

Mar1016   dehanne: sac, sac, sac, mate
Dragon variation in a nutshell. 

Mar1016   Cheapo by the Dozen: What I missed was that on
26 ... Kf7
27 Nxf6+
White's knight is covering g8, and hence 27 ... d5 allows 28 e6# So I didn't bother calculating out the lines after Black's other 26th move possibilities either. I like to think I've have played the correct line over the board, given the chance; at the point where I got stuck, White is down a pawn but has a raging attack. 

Mar1116   saturn2: with RxN 23..Be8 white was begging for RxNh7, so I would have fulfilled him this wish. Then instead of playing immediatly Rh1+ I went for e6, hampering the black position but offering the bishop on g5. After this there is Qf5+ or Rh1+. I dont have a computer but I think black is als lost in this way. 

Nov0916   clement41: Crushing attack.
I reckon this h4 h5, Bg5 Rc5 line was pionneered by Soltis but I may be wrong
