Jan-17-07  RonB52734: <Chesschatology> 28.Qh5 g6 29.fxg6 30.Qxe4 with a mate threat on e1 that must be answered, and it looks to me like the attack falls apart.
Jan-17-07  Eurotrash: rook sac jumped off the screen.
Jan-17-07  tjraczko: <hedgehog> After, 31.. Rf8 32 Qh7+ Kf7 33. Qg6+ Kg8 34 Nf6,......34. Rxf6, Qxe8+.
Jan-17-07  JustAFish: The nice thing about this puzzle is how vital the pawn on f5 is for the sequence to work. If it weren't there, the black king could escape the eventual mating by the queen and rook on h8 and h7.

Jan-17-07  hedgehog: <tjraczko> yes of course thanks, calculating without a board. Still it works just about. 34 Nf6+ Rxf6 35 Qxe8+.
Jan-17-07  Halldor: Got this up to Black's 30th move, there I continued: 30...♖f8 31.♕h7+ ♔f7 32.♕g6+ ♔g8 33.♘xf6+ <nice fork> ♖x♘ 34.♕x♕+ with a won position for White. I was happy with this and didn't see any forced mate. (Actually one of the first things I thought about in the puzzle was if a knight fork on f6 was maybe the key move somewhere in the solution.)
Jan-17-07  Chesschatology: <RonB5> Thanks!
Jan-17-07  CoryLetain: Rxh7 Kxh7 Rh3+ Kg1 Qh5. Must the queen move first?

  YouRang: Got it, although after 28. Rxh7+ Kxh7 29. Qh5+ Kg8 30. Rh3, I figured black would play 30...Rf8. I didn't notice that I could play 31. Nxf6+ right away, and I instead went with 31. Qh7+ Kf7 32. Qg6+ Kg8, and THEN 33. Nxf6+. Wins all the same...
Jan-17-07  NBZ: if 32. ... Re7 33. Nxf6+! (or Qh7+ Kf8 Nxf6 transposing) gxf6 34. Qh8+ and Rh7#.

<Chesschatology> After 28. Qh5 Qg8 is also possible, though as RonB52734 showed g6 is probably better.

  YouRang: <NBZ> <if 32. ... Re7> I presume you mean 32...Rfe7.

  kevin86: I answered this one correctly-actually,I saw the significance of Nxf6+ before I saw the rook and queen play. The rook and queen must be played first,of course.
Jan-17-07  chessdummy123: I got it in 20 seconds
Jan-17-07  Fisheremon: <NBZ: <Chesschatology> After 28. Qh5 Qg8 is also possible, though as RonB52734 showed g6 is probably better.> 28.Qh5 Qg8?! 29.Rh4 Bxd5 30.cxd5 Rfe7 31.Rch3 Rxe4 32.Qg6 ( )
Jan-17-07  Fisheremon: <RonB52734: <Chesschatology> 28.Qh5 g6 29.fxg6 30.Qxe4 with a mate threat on e1 that must be answered, and it looks to me like the attack falls apart.> 28.Qh5 also wins ! (a bit funny that one continues this line !): 28...g6 (28...Qg8 too passive and lost as shown in my previous message) 29.fxg6 Qxe4 30.Rhe3 Qb1+ 31.Kf2 Qxb2+ 32.Kf1 Rf8 33.Bh6 Bxd5 34.cxd5 Qb5+ 35.Rcd3 Rg8 36.g7+ ( )
Jan-17-07  Themofro: Got this one really quick, but it took me a while to find the obviuos Rh3 as i was to preoccupied on Nxf6 which would have won if not for gxf6,lol, which i initially overlooked. Nice game by white.
Jan-17-07  borisbadenoff: How about 30. ... Re7 31. NXe7 QXe7 the black actually get out of the situation. And even has a material advantage. I don't understand the meaning of 30. Ne2 it gives nothing to black.

  Ken MacGillivray: If 30... Re7 31.Nxf6+ wins.
Jan-17-07  alphee: Got it but,thinking twice,it seems that Black can escape through 28. ♖xh7+ ♔xh7 29. ♖h3+ ♔g8 30. ♕h5 ♖f8 31. ♘xf6+ ♖xf6 32.♕h8+ ♔f7 33. ♕h5+ ♔e7 but I did not explore any further...
Jan-17-07  GoHabsGo: alphee,
30.♕h5 ♖f8 31.♕h7+ ♔f7 32.♕g6+ ♔g8 33.♘xf6++
Jan-17-07  Magician of Riga: I've found that what makes a puzzle the most difficult is neither the length of the solution nor the involvment of sacrifices or multiple sacrifices. Its actually most difficult when the solution includes quiet moves that are not immediately forcing (i.e. not a check or a capture). In such case you're handing over the intiative for one or more moves and its rather unnerving as there substantially more variations to consider.
Jan-17-07  TheWhiteRider: Well said Magician...!
Jan-17-07  aazqua: This one is too easy. On a side note, Unzicker has to be the worst good player I've ever seen. That guy just plays crap all the time and gets his aspen handed to him.
Jan-18-07  alphee: <GoHabsGo:> true and the following is possible 33. ♘xf6+ ♖xf6 34. ♕h7+ ♔f7 35. ♕h5+ ♔e7 36. ♕h4 ♘e2+ 35. ♔f2 ....
Jan-24-07  aiannaccone: After 30. ... Re7 31. Nxf6+ Kf8, all I see is Nxe8. That gives black only a R&N for his Q & 2 pawns, but is there a decisive finish? I can't find one.

Better is 31. Qh7+ Kf8 32. Nxf6, threatening mate on g8. Both Qf7 and gxf6 fail, so black must move the R from e7.

32. ... Rf7 33. Qg8+ Ke7 34. Qxe8+ Kxf6 35. Qe5#

32. ... (Re6/Re5/Rxe4) 33. Qg8+ Ke7 34. Qxe8+ Kxf6 35. Qg6+ Kd7 36. Qxg7+ Kd8 and Bg5, Rh8, etc mates.
