  Jack Kerouac: Khalifman: 'You Rook Mahvelous!'
Mar-09-07  Wilsonia: There's a rook on h6! Where did that come from? I'm sure it wasn't there a minute ago. At least I'm not the only one who wants to play Qc6 at some point in the combination.
Mar-09-07  Rubenus: The first move is quite obvious, considering it is rook sac week, but I spent more than 5 minutes looking and I still didn't get how to continue. The actual combination is very nice.
Mar-09-07  zb2cr: Saw the first Rook sacrifice, missed the second. Bummer.
Mar-09-07  mkrk17: Simply too good. I missed this one. Lesson learnt.. ? If the opponents king is cramped and split open, then just a few pieces (queen and knight in this case) to deliver mate.
Mar-09-07  Marco65: <Gnappo> <mikrobi> Please help me understand: 28.Rxc7 Kxc7 29.Qxa7 Rb8 30.d6+ Rxd6 31.Nxd6 Kxd6 what now?

Also: 30...Kc8 31.Qa5 Qd8 and Black is cramped but what's the way to finish him?

Mar-09-07  realbrob: I also thought of 29.Qc6+ Kb8(only move) 30. Qxc7+ Ka8 but now I can't see a way to win by force. Anyone can help?
Mar-09-07  Themofro: Saw the first rook sac, missed the second though. Really nice mate.

  kevin86: A brilliant double rook sac-with twin captures of pawns at b7 and c7. White's threat of 32 Qc7# can be met by Rxd6-but it falls to the obvious 33 Nxd6#
Mar-09-07  JustAFish: I'm so close-minded sometimes. I saw the double rook sac theme, but couldn't make it work with Rxc7 coming first so I gave up. I also considered 28. Rxb7, but didn't follow it up with Rxc7, and, of course, couldn't make it work either. I never even considered reversing the move order so that Rxb7 comes first followed by Rxc7. Gotta' pay attention to that Lev Alburt maxim, "if all else fails, try reversing the move order."
Mar-09-07  Fisheremon: <Gnappo: <unclewalter: what happens if 28. Rxc7?> 28.Rxc7 Kxc7 29.Qxa7 Rb8 30.d6+! Kc6 31.Rd2! Nf6 32.Qa5 Kd7 33.Qxf5+ Kd8 (White has a big advantage, but the combination of the text is forcing)> 31...b6 32.Na5+ Kb5 33.Rd5+ Nc5 34.z4+ Kb4 35.Qxb8 with won endgame (as well as <Marco65: <Gnappo> <mikrobi> Please help me understand: 28.Rxc7 Kxc7 29.Qxa7 Rb8 30.d6+ Rxd6 31.Nxd6 Kxd6 what now?> 31.Rxb7+ Rxb7 32.Qxb7+ Kxb7 33.Nxd6+ <Also: 30...Kc8 31.Qa5 Qd8 and Black is cramped but what's the way to finish him?> 32.Nb6+ Nxb6 33.Qxf5+ Qd7 34.Rc2+ Kd8 35.Qg5+ Rf6 36.Qxf6+ Ke8 37.Rf2 a bit tricky but forced mate.)

<mikrobi: 28.Rxc7 Kxc7 29.Qxa7 Rb8 30.d6+! Kc6 31.Qa5! by fritz 8.> 31.Qa5?, cos' 31...b5 and Black's better (31.Qd4 winning)

Mar-09-07  Fisheremon: 26...Ne5? If played 26...Ne7 instead, how would White continue ?
Mar-09-07  orior: Man, it's really easy to miss that rook on h6.
and yeah, I should have been suspicious, it definitely looks like a tuesday puzzle without that rook there.
Mar-09-07  pggarner: <wolfking: why not 29. Na6+ ? and if 29... Kc8 then 30. Qc6>

Yeah, I was looking at 29.Na5+ (I.m sure that's what you meant) and then 30.Nc6 answering 29....Kc8 or 29...Ka8. Black has to play 30...Rxc6 and after 31.dxc6 White has mate in 2.

Mar-09-07  uuft: Yeeha! I totally found all the right moves. And in the right order, too. Well, kind of. !ahctoG q:

  fm avari viraf: A beautiful game by the World Champion Khalifman. With 2 Rooks sac. Black's fortress is in shambles & all Black's pieces watch in agony.

  YouRang: I didn't see it either. Lesson: The queen is a strong piece. It doesn't need much support to deliver mate.
Mar-09-07  Tacticstudent: got it pretty pretty fast. In fact, this is not a "difficult-finding" combination.
Mar-09-07  aazqua: This must be painfully obvious week. Maybe the whole puzzle thing is just too easy in general.

  OneArmedScissor: I understood the theme of blasting open the black king's position, but I missed the subtle move of the pawn.
Mar-09-07  Larsker: <euripides: Just in case you're wondering how Botvinnik would pay this position> Rubles?
Mar-09-07  Fezzik: Thanks Chessgames, for making difficult puzzles seem easy. This week's theme has been Rxg/b7 sacs, but the nuance this time was the relatively quiet d6.

I think I would have found the solution to today's puzzle even without knowing the theme because of the forcing nature of the attack. Still, Khalifman's gem deserves to be remembered.

Mar-09-07  ALEXIN: Very impressive but note that the black long castle is under heavy pressure. There are 4 pieces attacking and only two defending. Moreover the black queen is a little far from the struggle.
Mar-21-09  WhiteRook48: and Serper once played a tremendous sacrificial game himself
